Abstract: Communication in academic setting is necessary for all researchers in any field. One of the ways of this communication is through article writing. Therefore analyzing the features of articles in different disciplines is essential. Hence, the purpose of this study was to analyze the use of hedges, as one of the important elements in academic writing, in psychology discipline. To this end, 30 research articles written by American authors as Native Authors (NAs), Iranian Authors (IAs), and Turkish Authors (TAs) were selected and their discussion section were analyzed. After applying chi-square procedure for groups, it was found that significant difference existed between NAs and non-native authors. This means that IAs and TAs used more hedges in their writings. However, there was no significant difference between IAs and TAs. This can be meant that the regional norms in Iran and Turkey are the same. If non-native psychology researchers want to publish their works in international journals they should adapt their hedges to the standard norms in their discipline.

Abstract. Objective. We evaluated the efficacy of probiotics in reducing the incidence of feeding intolerance, necrotizing enterocolitis (NEC) and sepsis in full-term, bottle fed hypoxic ischemic encephalopathy (HIE)infants and verifies the viability of probiotic bacteria Lactobacilli in the stool and fecal IgA when lyophilized Lactobacillus acidophilus(L. acidophilus) was fed to those infants. Patients and Methods. A prospective, double blind, randomized, controlled clinical trial was conducted on 60 full-term newborns suffering from HIE grade II or III. They were randomized into 2 groups; the infants in the probiotic group were fed with lyophilized L. acidophilus in dose of 6 x 109 CFU divided into 2 doses/day in addition to the traditional HIE therapy until discharged while infants in the control group were given the traditional HIE therapy alone. Lactobacilli count and fecal IgA were determined at both day 7 and the end of the study. Primary outcome include NEC and sepsis. Results. A total of 60 HIE neonates were enrolled: 30 in the probiotic group and 30 in the control group. The incidence of NEC and sepsis was significantly lower in the probiotics group (16.7% vs. 33.3%, P=0.034 and 26.7% vs 73.3%, P= 0.0008, respectively). The fecal IgA concentration was significantly increased from day 7 to the end of the study in the probiotic group (6.91), but not in the control group (2.81.2, P<0.0001).Conclusion. The supplementation of lyophilized Lactobacilli acidophilus in full-term newborns with HIE grades (II,III) was beneficial, as it enhances the tolerability to enteral feeding and decreases the incidence of feeding intolerance, NEC and sepsis in our neonates.

Abstract: Objective: Determine the clinical response of post obturation pain after root canal obturation by using Obtura-II and System-B as root canal filling techniques and document the better success rate of thermoplastic technique for root canal obturation. Method: This study was a Cross-sectional comparative, clinical study.  A total of 60 patients, divided in two groups of 30 each Group-A (Obtura-II) and Group-B (System-B). These cases were treated at Operative Dentistry Department, Institute of Dentistry, Liaquat University of Medical and Health Sciences Jamshoro during the period 20th Feb.2009 to 26th Aug. 2009. Data was analyzed by using statistical package of social sciences (SPSS) Version 10. The mean difference, standard deviation, range and frequency of both quantitative and qualitative variables developed with the help of SPSS analysis. Results: A total of 60 patients required endodontic treatment were included in this study and canals were obturated by two thermoplastic techniques. Patients were equally divided into two groups by using envelop method, for group A, root canals obturated by Obtura-II and group B by System-B. The result of this study shows not much significant different in post obturation pain within 72 hours between Obtura-II technique and System-B technique. But there is little edge to System-B over Obtura-II, may be because of inflammation due to heat of warm gutta-percha in the apical tissues. Conclusion: After the comparisons of post obturation pain within 72 hours between groups and after stratification of gender, age groups and location presented in table-4. Gender and age groups were not having effect on post obturation pain. While location of the tooth was having effect on post obturation pain in the first 24 hours of the treatment.

Abstract: Objective: this study was meant to help physical therapists determine whether phenytoin phonophoresis has better effect than topical application alone on the healing process of the burn wound. Moreover, it is meant to determine whether pulsed or continuous phonophoresis is the best to achieve optimum burn wound care. Procedure: forty five adult male Sprague-Dawley rats were used in this study ranging between 10-12 weeks of age, and weighing 200-250g at the start of the experiment. One deep full thickness (third degree) burn wound was induced on the trimmed back of the neck by contact for 10s with 127oC heated metal stamp, 500mm2 in area. The rats were randomly divided into three equal groups; each group included fifteen rats. The pulsed phonophoresis group (PPG) was treated with pulsed ultrasound (I=0.8W/cm2 and F=3MHz for 5minutes) and phenytoin, the continuous phonophoresis group (CPG) was treated with continuous ultrasound (I=0.8W/cm2 and F=3MHz for 5minutes) and phenytoin, and the control group (CG) received topical phenytoin application with placebo ultrasound. RESULTS: The findings showed significant difference in favor of the continuous phenytoin phonophoresis group (CPG) over the other two groups, i.e. the pulsed phenytoin phonophoresis group (PPG) and the control group (CG). Thus, these results support the suggestion that the application of continuous phenytoin phonophoresis over the burn wound is very effective in accelerating the burn wound healing than topical application of phenytoin or pulsed phenytoin phonophoresis over the burn wound.

Abstract: Kazakhstan in system of the Eurasians integration with justification of its strategic effect by the main components – the institutional basis having special value for successful realization of integration policy. In this article the specification of Customs Union organization in the system of Eurasian integration is disclosed with substantiation of its strategic effect on basic components such as institutional basis, integrations of trade market and capital as well as labour market. Almost any state cannot develop its economy efficiently without taking into account geo-economic tendencies and geopolitical interests. At this time, national management systems are in dynamical integration area, experiencing both positive and negative influences of external challenges: from attraction to various integration processes to common crisis cataclysms, as it has been taking place lately. For many relatively young independent states, which also concern former Soviet republics, integration in the world system of management required to carry out radical changes in its institutional basis, motivational and adaptive mechanisms in various spheres of social and economic life. In this case, the specificity of integration relations organization in Eurasian community is thought to play a significant part, and first of all, in the format of Customs Union with its strategic effect substantiation which is formed by new institutional basis of integration, expansion of the competitive environment as well as goods turnover, and also resource potential, including the field of general labour- market development.

Abstract: Introduction: The prevalence of obesity is increasing worldwide. The prevalence of overweight and obesity in Egypt ranges from 74% to 86% in women and 69% to 77% in men. These data indicate a much higher prevalence of obesity among adult women, while overweight is more marked among adult men. One of the debatable issues which cause obesity is the meal frequency. Objective: The present study aimed to investigate the effect of nutritional education and increasing the meal frequency into six or more meals on weight loss and some health markers improvement. Methods: The present pre-post study was conducted on 100 females with BMI of ≥30 aged from 20- 55 years old who are attending obesity outpatient clinic in NNI in a periodof 3 months. Eating behavior was assessed using 24 hours food recall. All subjects were subjected to anthropometric, laboratory measurements in the form of (Fasting, 2 hours postprandial glucose level, Lipid profile which include serum cholesterol, triglyceride, high density lipoprotein and low density lipoprotein) and dietary education.Afterwards, they were required to have 6 meals per day. In the second visit, all subjects were subjected to anthropometric, laboratory measurements. Results: Increasing the meal frequency and nutritional education led to reduction in BMI, waist circumference, serum FBS, 2hpp, TG, and total Cholesterol, these changes were statistically significant. Despite the decrease in LDL, these changeswere not statistically significant. Conclusion: The increase in the meal frequency and nutrition educationled to reduce in Anthropometric measurements and improvement in serum glucose and lipid profile control.

Abstract: Parkinson disease (PD) is a common neurodegenerative disorder, which affects a central nervous system and it is characterized by progressive loss of muscle control. The diagnosis decision of PD is obtained by clinical observation which relies on expert human observer. Therefore, an additional classification method is desirable for most comfortable and timely detection of PD as well as faster treatment is needed. Many acoustic studies have been documented that the analysis of laryngeal, respiratory and articulatory function may be useful in the diagnosis of PD patient. Therefore, in this study, we develop and validate automated classification algorithms, which are based on Nave Bayes and K- Nearest Neighbors (KNN) using voice signal measurements to predict PD. The results show that our automated classification algorithm using Nave Bayes is outperformed KNN and it is useful as a predictive tool for PD screening with a high degree of accuracy, approximately 93.3%.

Abstract: In this study, three types of nutrition intended for infants were selected, treated with storage mites, Suidasia nesbetti were raised in the laboratory in a suitable environment, then culturing 100 mites in each sample and preserving them in different places in each selected kitchen at temperature and humidity varying relatively for a period of six months including autumn and winter. Fifteen houses having the same characteristics were chosen in terms of the region, age of the building, standard of living, the level of hygiene in the house, number of family members which on average was eight members per family home, and the level of health education. The samples were examined after opening directly to make sure of the safety and suitability for the secure feeding, and the examination was conducted periodically, every two weeks after storage to estimate the population dynamics of the mites with increasing duration for storage by one gram of each sample at the various houses and places. The study showed the highest population dynamics of the samples to be stored in Sealed box In Kitchen Cupboard, Kitchen Cupboard, Kitchen Shelf, Fridge, and finally Freezer which showed a significant decrease in population dynamics resulted in a reduction in the activity of reproduction and growth resulting from the lack of the appropriate conditions. The study found the greatest increase in the population dynamics of mites in the milk (M1), followed by (M2) and sweetened wheat powder (P) respectively, causes by the presence of specific factors leading to these differences in the chemical composition of the material, evidenced by the integration of all the environmental conditions for all samples, and the physical examination of the preserved materials a change in the color, smell, agglomeration of the powder (milk powder, sweetened wheat) resulted in a high level of humidity and the chemical reaction for the biological activities of the mites inside the selected materials.

Abstract: Mind Management is an emerging concept in psychology that has been applied to a wide range of fields. It is based on special principles aimed at raising one's self-awareness. This practical ability leads to personal growth and development because of the training and programming of the mind, especially the subconscious mind. Considering the functional importance of the subconscious mind and its vast responsibilities, Mind Management deals largely with managing and controlling the subconscious mind. The present paper adopts a novel approach to Mind Management by introducing a new concept conceived by the authors: the Mental Territory. In this context, Mind Management is the technique of managing the Mental Territory, controlling it and finally taking advantage of the mind’s remarkable abilities to control the surrounding world. As a result, a person who practices Mind Management has the ability to deal with the challenges posed by fast-paced changes. Such a person can make the best decision in every single situation through employing the special principles of Mind Management and so controlling the mind. Overall, the intention of the authors is to answer the following three important questions: (1) Why is Mind Management needed? (Why has peace of mind been lost?); (2) What is Mind Management? (A novel approach); (3) What is needed before achieving Mind Management?

Abstract: Seed dormancy in the population of Cassia fistula from Covenant University, Ota, Ogun State, Nigeria was investigated through laboratory experiments with a view to elucidate the best method that can be used to enhance maximum germination of the seeds. The treatments were mechanical scarification, aeration, hot water immersion, chemical methods and a combination of the treatments on seeds of different storage times. Percentage germination, mean germination time and germination rate were calculated at the end of the 20-day experiments. Results showed that mechanical scarification with wood sand paper, hot water immersion and concentrated sulphuric acid were the best treatments that significantly enhanced seed germination. Treatments with aeration, dilute sulphuric acid, 10% and 20% potassium permanganate and copper sulphate solutions did not significantly enhance germination in both the scarified and unscarified seeds. Dormancy in C. fistula appears to be primary exogenous type. The freshly harvested seeds germinated best with germination decreasing with storage time. Mechanical scarification in conjunction with either hot water immersion or concentrated sulphuric acid scarification are the most efficient methods for rapid and uniform germination of C. fistula seeds for use in afforestation, landscaping and pharmacological programmes in Nigeria.

Abstract: Proper diagnosis based on sound investigations is the key for a successful treatment. Meanwhile, treatment plans should be prepared accurately, and designed according to each individual case. The presented case could be an example of how far a wrong diagnosis and mismanagement can lead to a shift in the treatment plan, from a simple conservative treatment to a complicated and risky one. It describes a mismanaged facial pain, at the area of the right temporo-mandibular joint (TMJ), that eventually lead to exposing the patient to a risky operation under general anesthesia. A maxillary third molar, that was wrongly attributed to be the cause for the facial pain, was displaced upward and backward into the infra-temporal fossa (ITF) during an attempt for its extraction. An operation to retrieve the displaced tooth from the ITF was then a mandate. The operation was planned based on accurate determination of the position of the tooth, guided by interpreting a Pan-ortho-tomogram (OPG) and axial and coronal cuts of Computed Tomography (CT) scan. The intraoral approach to this risky skull base potential space was tried up to its limits. Further, an extra-oral pre-auricular incision with temporal extension was added to the intraoral one. The combined approach allowed reaching the tooth and retrieving it safely.

Abstract: Estrogen receptors (ERs) expression has been studied in salivary gland tumors, however, there are conflicting results regarding its expression in the literatures. The aim of this study was to investigate the expression of estrogen receptors protein (ERs) in pleomorphic adenoma (PA) and mucoepidermoid carcinoma (MEC) of salivary glands using immunohistochemistry. 35 cases of intraoral minor salivary glands tumors including 20 cases of MEC and 15 cases of (PA) were examined by a light microscope and immunohistochemistry for (ERs) expression. Five cases of normal salivary glands or of normal salivary gland tissues adjacent to the tumor were also used as control. A positive brownish staining of ERs was observed in ductal cells of normal salivary gland tissues. In MEC the expression of ERs was detected in tumor cells in 10 cases out of 20 (50%). The staining was either nuclear or cytoplasmic. The positive staining was strong (+++) in 4 cases (20%), moderate (++) in 4 cases (20%) and weak (+) in 2 cases (10%). Negative staining of ERs was detected in 10 cases (50%) of MEC. All cases of PA showed negative staining for ERs. This result indicated that ERs is not frequently expressed in salivary gland tumors and it may have a role in pathogenesis of MEC, but it does not play any significant role in tumorgenises of salivary gland PA.

Abstract: Background/Aim: There is no reliable laboratory test to predict the beginning or the end of Systemic Lupus Erythematosus (SLE). Soluble vascular cell adhesion molecule 1 (sVCAM1) is a new promising marker of SLE activity The aim of this work is to study sVCAM1 in SLE patients and to copmare with other traditional markers. Methods: Thirty SLE patients divided according SLE Disease Activity Index (SLEDAI) into 20 SLE patients with active disease had SLEDAI above 5 (group I) and 10 SLE patients with inactive disease had SLEDAI   less than 5 (group II) were compared versus 10 controls (group III) regarding Anti ds-DNA antibodies, Complement 3 (C3) & Complement 4 (C4) and soluble vascular cell adhesion molecule 1 (sVCAM1). All markers and disease activity index SLEDAI score, C3, C4, sVCAM1 & Anti-ds DNA levels were measured 3 times over 6 months ,at the beginning (the baseline measurement ) and 3 and 6 months after joining the study. Results: Anti ds DNA and sVCAM1 were significantly increased while serum levels of C3 & C4 were significantly decreased in group I compared to group II and III .There was significant positive correlation between SLEDAI score and   Anti ds DNA and sVCAM1 in groups I and II.  Also there was significant negative correlation between SLEDAI score and serum levels of C3 & C4 in group I but not in group II. At the end of the follow up visits, patients were classified into two subgroups according to SLEDAI score: score less than or equal 5 (inactive group) and score more than 5 (active group). At the end of the follow up visits, patients were classified into two subgroups according to SLEDAI score: score less than or equal 5 (9 patients) and score more than 5 (7 patients). The statistical analysis between the two groups showed that the serum levels of  Anti ds DNA was insignificantly lower in the inactive group while C4 levels were insignificantly higher. On the other hand, sVCAM1 was significantly lower in the inactive group while C3 levels were significantly higher. Conclusion: sVCAM1 is important laboratory parameters for assessing disease activity especially in patients with anti-dsDNA negative. Serial estimation of these serological markers helps  in predicting  lupus flare during follow up.

Abstract: Sedimentary rock samples from Late Triassic – Jurassic Formations at Wadi El Bih and Wadi Milaha in the northern part of the UAE have been analyzed using various geochemical methods in order to decipher their organic signature. Examination of the distribution of total organic carbon (TOC) at Milaha Formation (0.07wt% –2.60 wt%) with average 0.82 wt%, Ghalilah formation (0.04wt% - 0.22 wt%) with average 0.11 wt%, and Musundam Formation (0.05 wt% - 7.70wt%) with average 0.73 suggests that the petroleum potential of the Late Triassic – Jurassic Formations should be taken into consideration. The Late Triassic - Jurassic episodes permitted the accumulation of organic matter, which is typically shallow carbonate plateform as indicated by the unimodal distribution of N-alkane. It is concluded that the organic matter of the Late Triassic - Jurassic is marginally mature, as indicated by the high content of (0.01% – 0.1%) in bitumen, suggesting that the organic matter has been maturedat the beginning of catagenesis. These new results testify to the establishment of suboxic conditions that led to the accumulation and preservation of good quantities of organic matter in the northern part of UAE. However, the results of pyrolysis-gas chromatographic analyses showed that the organic matter of the Late Triassic - Jurassic Formations is rich in sulphur compounds. The presence of sulphur-rich kerogen resulted in the early generation of hydrocarbons from this unit. The results of multi-step Py-GC analyses indicated that the composition of hydrocarbons generated in these two carbonate source rocks will be different, particularly during the early stages of maturation. The Late Triassic – Jurassic sediments could generate mature oil (effective source rock) whereas the Jurassic deposites could only generate oil if subjected to high thermal maturity (relic effective source rock). Based on the obtained results, the Late Triassic – Jurassic sequence has a source organic facies in the northern part of UAE.

Abstract: Aim of the work: To compare the surgically induced astigmatism, financial cost, intraoperative difficulties and complications and postoperative complications and visual outcome of manual sutureless small-incision cataract surgery (SICS), planned extracapsular cataract extraction and phacoemulsification. Design: Prospective, randomized comparison of 60 consecutive patients with mature cataracts. Methods: Sixty consecutive patients with mature cataracts were assigned randomly to receive either MSSICS, planned extracapsular cataract extraction (ECCE) and phacoemulsification. Intervention Cataract surgery with implantation of intraocular lens. Measures: Operative time and coast, surgical complications, uncorrected and best-corrected visual acuity (BCVA), surgically induced astigmatism. Results: these surgical techniques achieved excellent surgical outcomes with low complication rates. On postoperative day 1, the groups had comparable uncorrected visual acuity (UCVA) (P _ 0.185) and the MSSICS group had least corneal edema (P _ 0.0038). At six months, 92% of the MSSICS patients had UCVA of 20/60 or better and 98% had a best-corrected visual acuity (BCVA) of20/60 or better vs 85% of patients with UCVA of 20/60or better and 98% of patients with BCVA of 20/60 or better at six months in the phaco group (P _ 0.30).Surgical time for SICS was much shorter than that for phacoemulsification (P <.0001). Conclusion: MSSICS, planned ECCE and phacoemulsification achieved excellent visual outcomes with low complication rates ECCE is significantly faster, less expensive, and less technology dependent than MSSICS and phacoemulsification but with higher surgically induced astigmatism than MSSICS and phaco.MSSICS may be the more appropriate surgical procedure for the treatment of mature cataracts in the 3rd world countries.

 Abstract: A scanning electron microscopy (SEM) study during the induction of embryogenesis from cell suspension culture of (Phoenix dectylifera L.) cv. Gundila showed that somatic embryogenesis had different developmental stages such as embryo with globular shape as the first stage of somatic embryogenesis followed by torpedo shape as the second stage and finally matured embryo as the third stage in comparison with zygotic embryo. Results from Energy dispersive x-ray microanalysis (EDX) during induction of embryogenesis showed no differences between mature somatic and zygotic embryos in C, O, N, K, Na, Cl, and Zn elements accumulation while there was difference in Al, Ca and Cu accumulation obtained for both mature somatic and zygotic embryo. So we suggest that Energy dispersive x-ray microanalysis (EDX) can be used as signal marker to distinguish between somatic embryo stages.

Abstract: Diabetes mellitus (DM) is a global epidemic disease and the alarming increase in its prevalence is one of the major challenges to modern health care. Therefore, with a rapid increase in the prevalence of DM, ocular complications have become a leading cause of loss of vision in the world. Diabetic retinopathy (DR) is the most common complication in diabetic patients. Although it has long been considered a microvascular disease and that the blood-retinal barrier (BRB) breakdown is a hallmark of this disease, DR has also recently been viewed as a neurodegenerative disease of the retina. Therefore, this study was carried out, for the first time, to throw more light on the role of ginger extract on the retinal complications in a streptozotocin (STZ)-induced rat model of DM including its effect on both caspase-3 and vascular endothelial growth factor (VEGF) expressions. Diabetes was induced via a single intraperitoneal injection of STZ (50mg/kg body weight) and ginger was administered orally (500mg/kg body weight daily). Animals were sacrificed 4th, 6th & 8th week after induction of DM. Body weight, blood glucose level, and glycated haemoglobin were measured. Retinal specimens were subjected to histological (both light and electron microscopic), histochemical, immunohistochemical and quantitative studies. It was found that caspase-3 & VEGF have played a pivotal role in the damaging effect of the DR induced by STZ and that ginger supplementation considerably mitigates these damaging effects.

Abstract Diarrhea continues to be one of the most common causes of morbidity and mortality among travelers and residents of developing countries especially infants and children. The aim of this study was to isolate E. coli from cases of diarrhea in children. A case-control study was conducted in 150 samples from children younger than fifteen years of age in Egypt (135 cases and 15 controls). Diagnosis of infection with this subclass of E. coli can be performed with conventional biochemical reactions and API 20E system. 87 bacterial isolates (E coli), 22 isolates (Klebsiella spp), 4 isolates (Serratia marcescens), Enterobacter spp (3 isolates) and 9 isolates (non lactose fermentation species) were obtained. There is significant effect between age groups and the percentage of isolated species (P > 0.05) but there is no significance for sex, fever and duration of diarrhea and isolates from each species (P < 0.05). The presence of genes encoding a heat-labile toxin (LT) and a heat-stable toxin (ST) was detected in fifty E. coli isolates by multiplex PCR. The result showed that, seventeen (34%) enterotoxigenic E. coli (ETEC) strains were found. Ten strains (20%) expressed ST, two (4%) expressed LT and five (10%) expressed LT&ST. This study supports the fact that ETEC is still a major cause of childhood diarrhea in Egypt, and that measures to prevent such infections are needed in developing countries.

Abstract: Nanotube oxide layer formation was achieved from biomedical titanium using anodization technique in 1 M H3PO4 + 0.8 wt.% NaF. The effect of anodization time and potential was studied. The nanotubes surface was characterized using SEM, and the electrochemical behavior was investigated employing open circuit potential, electrochemical impedance spectroscopy and potentiodynamic polarization measurements in Hank's solution. The results indicate that there is a minimum potential required for the formation of titanium nanotubes. The oxide nanotubes length and diameter vary with anodization potential, leading to a different electrochemical behavior in Hank's solution. The titanium oxide nanotube formed at 20 V has the lower Icorr and higher Ecorr, which indicates the best stability in Hank's solution. On the other hand, the duration of anodization process up to 2 hour doesn't have a pronounced effect on the surface morphology, but it can change the stability of titanium oxide nanotubes, which was indicated by the electrochemical parameters. This effect can be attributed to the rate of the dissolution reaction occurring at the titanium oxide nanotube surface in Hank's solution.

Abstract: Background: Functional Transcranial Doppler (fTCD) is an efficient reliable method for detecting cerebral lateralization; however very few studies were interested in its application in multiple sclerosis (MS) clinical settings. Objective: Our purpose was to investigate whether lateralization index for language is altered in multiple sclerosis patients using fTCD and its relation to adaptive cognitive functions. Methods: The study recruited 20 multiple sclerosis patients and 20 healthy control subjects matched for age, sex and handedness. Using fTCD lateralization index for language was calculated in both groups. To assess clinical disabilities due to MS, we used Multiple Sclerosis Function Composite (MSFC), Expanded Disability Status Scale (EDSS) and the Edinburgh Handedness Inventory (EHI). Results: Multiple sclerosis patients showed more bilateral activation for language tasks compared to controls (P < 0.001). Lateralization index in patients showed high significant correlation with the disease duration (P value < 0.01). Functional TCD lateralization index revealed a significant correlation with the PASAT scores (P value <0.05), however it showed no correlation Timed Waked Test TWT or the nine Hole Peg Test (9HPT). In addition there was no significant correlation of fTCD lateralization index with either the EDSS or the Edinburgh Handedness Inventory scores. Conclusion: Functional transcranial Doppler should be more entertained in investigating cognitive dysfunction in multiple sclerosis patients. It may offer a future promising tool for diagnosing and following up treatment and rehabilitation effects.

Abstract: Background: Nanotechnology is emerging as a rapidly growing field with its application in science and technology for the purpose of manufacturing new materials at the nanoscale level. Application of such field in dentistry and periodontitis in particular may have a great potential in the regeneration of tooth supporting structure as the chronic periodontitis is one of the problems affect a major part of the world population. The aim of current study: was to regenerate periodontal tissue defect using hydroxyapatite nano particles (HANP) and compare its regenerative potentiality with autogenous bone graft (ABG). Material and Methods: Chronic periodontitis was induced in twenty seven, 13–16 months old Beagle dogs. After one month of inducing chronic periodontitis, the animals were distributed randomly into equally three groups: Group I (conventional group): Treated with open flap debridement. Group II (ABG group): Treated with open flap debridement and ABG. Group III (HANP group): Treated with open flap debridement and HANP. Three dogs in each group were sacrificed with overdose of Phenobarbital sodium salt at day 1 and at 6th & 12th weeks after the surgical procedures. Then the specimens were processed for subsequent histologically by H&E and immunohistochemically by Matrix Metalloproteinase 9 (MMP-9) antibody and Collagen -1 (Col-1) antibody. Results: At day one after surgical procedure all animals showed signs of gingival inflammation, apical migration of attachment epithelium and destruction of the periodontuim. In group I, after 6 and 12 weeks, the signs of degenerative changes of periodontium became less. Nevertheless, the signs of complete periodontium regeneration were not clearly seen. While treatment with surgical conventional procedure and ABG showed successful tissue regeneration which became more advanced in animal treated with both conventional procedures and HANP. The immunohistochemical & statistical results confirmed these histological findings. As Tukey’s post hoc test for both MMP9 and CO-I intensity revealed that the difference between each two groups was statistically significant, except for the difference between group II and group III at the 6th and 12th weeks and between all groups at the day one. Conclusion: There was no notable difference between the healing effect of HANP and the ABG which considered the gold standard osseous graft material providing a promising insight into the application of nanotechnology in the periodontal diseases management.

Abstract: The present work deals with applying compo-casting technique for fabrication of magnesium matrix composite under an inert gas atmosphere. A 15 Micrometer average diameter size of -SiC particulate was used as a reinforcement material with different volume fractions. The effect of processing technique on SiC distribution within alloy matrix was investigated using light optical microscope and scanning electron microscope. Also, microstructural characterization studies conducted on the composites produced by compo-casting technique revealed a uniform distribution of SiC particulates (at the microscopic scale) and less porosity content. The mechanical properties of pure Mg and Mg-SiC composites have been evaluated. The results show a remarkable increasing in hardness value, tensile strength and 0.2% yielding strength. The increasing in overall mechanical properties revealed to SiC addition to base matrix. However, it is also evident that the strain to failure significantly decreased as the volume fraction of the particulate increased. Also, a good bonding between Mg matrix and SiC reinforcement material was observed in fracture surface SEM micrograph.

Abstract: Aim of the work: to evaluate clinical and radiological outcome after treating twenty patients having unstable intertrochanteric fracture femur by Bipolar Hemiarthroplasty. Methods: In this study; the method divided into preoperative planning, operative technique, post-operative management and follow up. Patient selection: Age: 55 years old or older, Radiological diagnosis of an unstable intertrochanteric femoral fracture. Type of the fracture According to AO classification.31-A1.3, 31-A2.1, 31-A2.2& 31-A2.3 Osteoporosis According to Singh index grade 4, 3, 2 and 1 are included in our study. So X ray to the neck of the opposite side femur was done for assessment of the bone quality of the patient. Surgical approach and positioning Lateral (modified Harding) approach was used in all patients with the patients in the lateral decubitus. The pelvis in rigidly immobilized and the limb draped separately. Functional outcomes (pain, activities, gait and range of motion) were assessed based on the Harris hip scoring system. Results: all patients were 55years old or above. Follow up period ranged from 2 weeks to 6 months. 16 patients out of 20 have completed the follow up period.: at last follow up, the Harris Hip Score ranged from 93 to 72 with a mean value about 82.5. Intra-operative Fracture (case 13): during application of the femoral stem an inta-operative fracture of the femur has been occurred which was fixed using cerclage wire. One patient has developed deep infection two weeks postoperatively. Haematemesis(case 5): in the same day after operation the patient developed haematemsis from bleeding stress ulcer. Conclusion: Hemiarthroplasty using bipolar prostheses for the unstable intertrochanteric fractures of the femur in elderly has good clinical results; early post-operative ambulation with no post-operative DVT, chest infection nor bed sores. This will have a direct effect on the general condition and the post-operative rehabilitation.

Abstract: Rheumatoid arthritis affects ~1% of the adult population; and cardiovascular disease complications are the common cause of death. Search for markers to predict occurrence or severity of cardiovascular disease in rheumatoid arthritis is very important. We intended to measure the concentrations of tumor necrosis factor-α in rheumatoid arthritis and correlate it with cardiovascular disease development. One hundred patients with rheumatoid arthritis were included and all subjected to full history taking, clinical examination, and laboratory investigations. Diagnosis of cardiac disease was done by stress electrocardiogram, Echocardiography or resting trans-thoracic echocardiography and color Doppler). Finally tumor necrosis factor-α was measured. Results: Cardiovascular disease was reported in 88% of cases; there was significant increase of Tumor necrosis factor in cases rheumatoid arthritis with cardiovascular disease when compared to those without (27.269.06 vs 13.794.98 respectively). In addition, there was significant increase of cases with high TNF in RA cases with CVD when compared to cases without CVD (79.5% vs 16.7% respectively, p < 0.001). Furthermore, 81.4% of carotid atherosclerosis cases had higher TNF alpha. In addition, 73.5% of heart failure cases, 76.7% of valvular affection, 73.3% of ischemic heart disease cases; 61.5% of pericardial effusion cases; all cases with pulmonary hypertension and 80.0% of cardiomyopathy cases had higher TNF alpha. Conclusion: TNF-α was found in a higher concentration in RA with CAD when studied collectively or when study each disease individually. Thus, there is a relation between TNF-α and development of CAD in RA patients. TNF-α thus can be used as a predictor of CAD development in RA patients or as follow up marker denoting the efficacy of therapy.

Abstract: Objective: To formulate orally disintegrating tablets (ODT) of Amoxicillin Trihydrate (AMT) suitable for pediatric use to combine the advantages of easy use, accurate dosing in a stable dosage form. Method: ODT were prepared by direct compression using Ac-Di-Sol, Sodium starch glycolate, Polyplasdone and Pharmaburst as superdisintegrants at different concentrations. Mannitol was added as diluent in all prepared ODT formulae except Pharmaburst based formula. The prepared tablets were evaluated for drug content, weight variation, hardness, friability, water absorption rate, and wetting time. In vitro/vivo disintegration time was estimated. In-vitro dissolution behavior of AMT from the prepared ODT at both salivary and gastric conditions was investigated. Finally; taste evaluation of the prepared ODTs was applied on healthy human volunteers. Result: All formulation blends showed good flow properties, uniform thickness, diameter, weight and good mechanical resistance and breaking strength. The wetting time was in the range of 90 to 43sec and absorption ratio range from 120.71 to 153.4. Polyplasdone and Pharmaburst based ODT formulae showed the shortest disintegrating time (44 and 45 sec respectively), disintegration in buccal cavity was between 22 and 60sec. Regarding dissolution results, F8 and F10 showed the highest dissolution rate (66.35% and 67.97% respectively) within 30 minutes in phosphate buffer pH 6.8. In 0.1N HCl, the percentage of drug released was more than 85% within 30 minutes from all prepared ODT formulae. Formulae 8, 9 and 10 showed the highest dissolution (AMT released reached 100% within 15 minutes). Conclusion: Depending on the previous results it can be concluded that the proposed ODT formulae of AMT are suitable and efficient substituent for the commonly marketed suspension for pediatric use.

Abstract: Background: Upper gastrointestinal bleeding associated to esophageal varices is the most dramatic complication of cirrhosis. It is recommended screening every cirrhotic for esophageal varices with endoscopy. Aim of the work:-The objective of this study was to investigate the PC/SD ratio as a predictor of the presence and absence of esophageal varices in Egyptian patients with liver cirrhosis. Patients and methods:-One hundred and twenty five cirrhotic patients were included from the Hepatology department; Al-Azhar Faculty of Medicine and Ahmed Maher Hospital during the period from June 2011 till Feb. 2012. The diagnosis of hepatic cirrhosis by physical, biochemical, and imaging examinations, and confirmed by histological examination of Tru-cut needle-isolated liver biopsy. Once the patients were included in the study, a complete medical history was taken, medical examination was performed and biochemical parameters were measured. Results: - Comparison between cases with EV and those without EV was presented in table 2; and results showed that, age was significantly increased in cases with EV [50.325.26 vs. 44.514.38]. In addition, hepatic encephalopathy and ascites were significantly increased in cases with EV [25.6%, 47.7% vs. 7.7%, 28.2% respectively]. Cases with EV had higher grades of child Pugh scoring, low platelet count [117711.5016529.65 vs. 205905.8927809.35], high Pugh score [9.292.78 vs. 6.531.87], high spleen diameter [158.0911.20 vs. 145.797.82], and low PC/SD ratio [751.71138.30 vs. 1421.21239.27]. Running ROC curve, it was found that, the test had a good diagnostic accuracy [AUC= 0.99]; the best cutoff value was 976.0 with sensitivity of 99.3% and specificity of 97.4%. Conclusion:-The PC/SD ratio is an accurate method for prediction of EV in cirrhotic patients and it can substitute it or at least can be used as a useful noninvasive method for identifying patients with esophageal varices and thereby may help reduce the number of unnecessary endoscopies

Abstract: Urinary tract infections considered as the most public Infectious diseases in the world. Escherichia coli are the most public Gram negative bacteria which causes of both community-acquired and nosocomial transmitted UTIs. Methodology: In present study, a total of one hundred and fifty of urine samples collected from children aged from one month to fourteen years old of urinary tract infection, and after the Positive cultures about fifty isolates were identified as E.coli. The mechanisms of resistance to antibiotics in E.coli isolates were evaluated by using the antibiotic susceptibility and the MIC which were determined through standard disk diffusion method and E-test strips; respectively. Results: The resulted antibiogram patterns of the isolates showed that many resistant strains possessed resistance to different group of antibiotics such as β-lactams, sulpha drugs, and quinolones. Genotypic determinations of the above resistance were done resulted in presence of TEM, SHV, CTX-M, Sul-1 and Gyr-A mediated genes. Conclusion: in this study concluded mandatory surveillance is recommended to be extended to include the community UTIs to allow gaining a better understanding of ESBL (Extended Spectrum Beta Lactamases) producing E.coli. And the Monitoring of antimicrobial resistance is necessary to avoid treatment failure in patients with urinary tract infections.

Abstract: Spread spectrum communications have increased interest due to their immunity to channel fading and low probability of intercept. One of the limitations of the traditional digital spread spectrum systems is the need for spreading code synchronization. Chaotic communication is the analogue alternative of digital spread spectrum systems beside some extra features like simple transceiver structures. Among the chaotic modulation schemes, the Differential Chaos Shift Keying (DCSK) is the most efficient one because its demodulator detects the data without the need to chaotic signal phase recovery, i.e uses noncoherent detection. In this paper, the design of a DCSK modulator and demodulator using the efficient design tool Matlab-Simulink provided from Math work Inc. is presented. The waveforms are obtained at different stages of modulator and demodulator to allow the reader to well understand the features of this modulation type. Performance curves of DCSK are given in terms of bit-error probability versus signal to noise ratio with spreading factor as a parameter. The simulation results showed that at 10-3 bit error rate, 0.5 and 1 dB gains in SNR is obtained when the spreading factor is increased from 60 to 80 and 100 respectively.

Abstract: The aim of this study was to investigate the effects of rapid palatal expansion (RPE) and facemask therapy on sagittal airway dimensions, hyoid position, and head posture in growing patients with skeletal Class III malocclusion. Fifteen cases (9 girls, 6 boys; mean age, 9.35 1.53 years) treated with RPE and facemask therapy were included in this study. Pre-treatment, post-treatment cephalometric radiographs were obtained.  Linear and angular measurements were traced. Data were analyzed statistically by means of Paired T-test. Treatment changes revealed a significant increase in nasopharyngeal and oropharyngeal airway dimensions. Significant increases also occurred in the sagittal growth of the maxilla, while a clockwise rotation and inhibition of sagittal growth were observed in the mandible. Significant change in head posture was observed while no significant positional change was noted in hyoid bone. Conclusion: Orthopedic treatment of Class III skeletal malocclusion with RPE and facemask therapy was able to produce a significant improvement in the nasopharyngeal and oropharyngeal airway dimensions and a significant change in the head posture.

Abstract: Introduction: Long-term hunger is a problem that all living species in the nature has to cope with. Hunger has a great effect on the metabolism and structure of many body systems. Several studies reported variable effect of starvation on organs; stomach, liver, thyroid and intestine. Aim of the work: to throw more light on the effect of both hunger and thirst on the gastric fundus of female albino rats by using histological, histochemical and immuno-histochemical methods. Materials and Methods Thirty adult female albino rats were subjected to experiment for 6 days. The animals were divided into 5 groups, each of 6 rats as follow: Group I: (control group) were allowed free access to water and food ad libitum. Group II: subjected to starvation for 1 day. Group III: starvation for 2 days. Group IV: starvation for 4 days. Group IV: starvation for 6 days. Animals were sacrificed by cervical dislocation. Specimens of the fundus of the stomach were excised, fixed in formol saline, processed to paraffin blocks and subjected to histological, histo-chemical and immune-histochemical studies. Results: Histologically and histochemically, congestion of some blood capillaries with extravasation of blood, shedding and desquamation of superficial epithelium were noticed after 1st day of starvation. A glandular cystic dilatation with flattening of their epithelial lining, degeneration and loss of some superficial epithelium was observed in the 2nd day of starvation. Some parietal showed vacuolated, pyknotic nuclei and distorted gland with gastric ulcer was noticed in fundic glands at 4th day of starvation. Multiple gastric ulcers with loss of gastric mucosa, destruction of muscularis mucosa and submucosa was reported on 6th day after starvation. Alcian blue stain showed strong reaction in mucus neck cells and faint reaction in the base of the gland which increased with increase hunger duration. Masson trichrome stain was expressed in collagen fibers in the lamina propria between the basal part of fundic gland which increased with more time of starvation. Immune-histochemical, all starvated group stained by caspas 3 showed positive immune reaction in the middle and basal part of the gland with increase intensity of reaction with increase hunger duration. Conclusion : Structural changes in the fundus of the stomach are in direct proportion with hunger duration.
