Abstract: Aim of the work: The objective of study is to determine the effect of the low level laser therapy on nerves regeneration after a compression injury of rat sciatic nerve. Study design: The injury of the sciatic nerve was induced by using portable deadweight device with a load of 5000g applied over a length of 5 mm for 10 minutes was used in this study on the crushing of the sciatic nerve of rats. This device is characterized as being a faster, easier and more reliable crushing process, in relation to the load used. The animals were divided into three groups, the animals in group III received LLLT daily for 28 consecutive days we used A Semi-conductor Diode AlGaInP Laser, formed a control console and a handheld probe. The diameter of the probe is 18 mm and it was used to deliver the LLLT. Functional nerve assessment was done using the foot step forms and sciatic nerve was dissected for histological examination to evaluate the regeneration of the sciatic nerve. Results: Found that significant differences of the times factor (F= 4765.53, P= 0.001), groups factor (F= 2222.54, P=0.0001), Also we found a significant differences of the interaction between times and groups factors (F=742.63, P=0.001) when sphericity assumed, Pillai's trace showing a significant differences for the time factor, group factor and the interaction between time and group factors. The histological assessment improve that the most axons of the Group III sections showed regeneration and a uniform arrangement. Conclusion: The Low level laser therapy is a useful way for treating the injuries of the nerves and when we use the LLLT at the early stage of the injury of the nerve it will helps in the minimizing of the loss of nerve functions.

Abstract: Background: The Testis is the main genital male organ that possesses both exocrine and endocrine gland roles. Melatonin is the code hormone of the pineal gland which is essentially produced during period of darkness and it is recognized to reach almost all bodily cells and organs regulating their function, especially the reproductive organs. Aims: This work was designed to study the effect of increasing periods of continuous darkness on testicular tissues. Methods: Eight groups of adult Wister albino rats were kept in complete 24 hours darkness intended for 4 successive periods. Groups II, III, IV and V were put in continuous darkness for two, four, six and eight weeks successively. Group Iᵅ, Group Iᵇ, Group I ͨ, and Group Iᵈ were the control groups for groups II, III, IV and V consecutively. After the last day of the dark period for each group, the rats were killed under effect of anesthesia. The right testis was taken, weighed and processed for morphometric as well as anatomical and histological study. Result: The results showed no important structural effect on short and medium periods of darkness, while on long periods; there were significant effects which were proportionate to the time length of darkness. Conclusion: The continuous darkness affects the testicular tissues of rats; hence, the reproduction status, depending on the length of exposure.

Abstract: The aim of the current study was to investigate the efficiency of recombinant bovine somatotropin hormone (rbST) and/or gonadotropin releasing hormone (GnRH) for induction of puberty in prepubertial buffalo heifers. Twenty eight buffalo heifers, aged 23.3±0.1 months and weighted 370.0±1.6 kg, were randomly allotted into rbST-GnRH treated (G1, n=10); GnRH alone-treated (G2, n=10) and control (G3 n=8). Both follicular populations and largest follicle diameter were detected by transrectal ultrasonography on Days -3 and 0 whereas Day 0 was the Day of GnRH injection. Also, serum IGF-1 and plasma glucose levels were assayed on Day 0.There was an increase (P<0.01) in the serum IGF-1 and plasma glucose levels in G1 on Day 0. Also in G1 heifers, there was a significant increase in the largest follicle diameter on Day 0 (13.6±0.8 m) compared to Day-3 (8.41±1.1 mm). The follicular populations in terms of small and large-sized classes were higher (P<0.05) in G1 compared to G2 and G3 as well. Both puberty induction and conception rates were higher (P<0.05) in G1 compared with other groups.In conclusion, the highest rate of puberty initiation in prepubertial buffalo-heifers is achieved when rbST is injected 3 days prior to GnRH.

Abstract: Background: Obesity in preschool period is a public health problem caused when the intake of calories and food exceeds the expenditures and lack of exercise. The most significant health consequences of obesity in preschool period are cardiovascular diseases, diabetes and musculoskeletal disorders that affect child quality of life. Pediatric nurses provide weight related health information to the mothers and school nurses using research evidence in designing health promotion program for families. Therefore, the aim of this study was to evaluate the effect of an educational program on mothers' knowledge and their nutritional habits about obesity among their preschool children. A quasi-experimental design was used in carrying out the study. The study was conducted at six nursery schools (3 private & 3 governmental) at Mansoura City. The study subjects included a convenience sample of 120 obese child and their mothers recruited over 6 month period. Data were collected by using three tools, child assessment sheet for the preschool child, interview questionnaire for mothers' knowledge and their nutritional habits about obesity and mothers' checklists for measuring preschool child's weight and height to calculate BMI. The study results revealed that there were statistically significant differences between the studied children anthropometric measurements before & post 3 months of the program implementation as well as there were statistically significant relations between the studied mothers' total knowledge and their total habits post 3 months of the program implementation. The study concluded that there was a positive effect of the educational program in improving mothers' knowledge & nutritional habits regarding their preschool children obesity. The study recommended regular and continuous health educational programs are essential for improving the mothers' knowledge and habits regarding preschool obesity.

Abstract: Background: treatment for patients with hormone refractory prostate cancer (HRPC) after failure of docetaxel-based chemotherapy remains controversial. The aim of this study was to assess the efficacy and tolerance of metronomic cyclophosphamide plus prednisolone in those patients. Patients and Methods: From June 2012 to December 2015, 29 patients with HRPC who failed on docetaxel-based chemotherapy received metronomic cyclophosphamide-prednisolone regimen. Twenty-nine patients received 50 mg oral cyclophosphamide and 10 mg rednisolone daily until disease progression. Results: Nine patients (31.03%) had stable disease with<50% reduction of PSA level, 8 (27.58%) patients had ≥50%, while 12 (41.37%) patients showed progressive disease. The median overall survival was 11 months (5.5-21 months) and the median progression free survival was 4 months (3-5.5 months). Treatment was well tolerated. Conclusion: low dose metronomic cyclophosphamide prednisolone was well tolerated with modest activity in HRPC who failed on docetaxel-based chemotherapy.

Abstract: In Nigeria and other developing countries, crop production and distribution could have been improved upon, if more attention is paid to the area of separation in the roles played by men women. This study, on gender basis, critically examined the technical efficiency and the determinants of technical efficiency among crop farmers in Oyo State, Nigeria. A structured questionnaire was used to collect data from 120 randomly selected respondents. The data were subjected to descriptive statistics and stochastic frontier production analysis. The results reveal that the mean ages for male and female farmers were 49.4 and 43.2 years respectively. Men (92.9%) are more educated than women (78.6%) respondents. The mean farming experience for men was 28 years while that of women was 16 years. On the average, male respondents were more visited by the extension agents than their female counterparts. The mean farm sizes for male and female respondents were 4 and 2 hectares respectively. The use of modern implement is not common in the study area. The results further reveal that there was a return to scale of -0.567 for male and -0.260 for female respondents. This shows that both categories of farmers are experiencing decreasing negative returns to scale. The determinants of technical efficiency among the male respondents were farmers age, educational level, access to extension services, access to credit and farmers association membership while that of female respondents were farmers age, educational level, access to credit and farmers association membership. The results again reveal that men crop farmers are more technically efficient than their women counterparts with mean technical efficient indices of 0.89 and 0.75 respectively. It was recommended that the crop farmers should re-organize the use of their variable and fixed resources in order to produce in the region where profit is maximized.

Abstract: Hyperprolactinemia is a common endocrinal alteration in chronic renal failure, Several investigators examined the serum concentration of prolactin in patients with chronic renal failure and found it to be elevated. The aim of the study: is to evaluate the relation between adequacy of dialysis and levels of serum Prolactin in long term hemodialysis patients, in order to clarify if adequate dialysis adds a benefit in lowering Prolactin levels. Method: Thirty Patients with chronic renal failure (males aged 35 to 70) who participated in this study were maintained on hemodialysis 3 times/week, 4 hours each session. Dialyser membranes were 1.4 m2 low flux Baxter. Duration of dialysis was more than 5 years for all patients Results: Our study revealed a statistically significant negative correlation between serum prolactin level and URR, i.e. the better the dialysis adequacy the less the serum prolactin level. Conclusion: As increasing dialysis adequacy would improve hyperparathyroidism, erythropoietin sensitivity and clearance of uremic toxins, this could all contribute to improved prolactin profile.

Abstract: Prevalence of Helicobacter pylori antibodies among patients that attended University of Port Harcourt Medical Center (UPMC) and Braithwaite Memorial Specialist Hospital (BMSH), Port Harcourt was investigated. The study determined the prevalence of H. pylori specific antibodies in blood samples of patients that attended both medical facilities (UPMC and BMSH). The study population consisted of 100 patients in the ratio of 0.5 from each hospital. Helicobacter pylori rapid test kit (ANTI-HP Rapid) was used to qualitatively detect antibodies to H. pylori in serum of subjects that were investigated and questionnaires containing information about the age, sex and other demographic details were also obtained from patients and recorded. The results obtained gave 22 (44.0%) for UPMC and 22(44.0%) for BMSH, indicating that there was no significant difference (p<0.05) among patients with the infection in both hospitals. This shows that the infection is predominant in the area irrespective of location. Similarly, the infection was not predominant with any sex since the ratio of male to female gave 42.9: 44.8 %. However, there was a significant difference (p>0.05) in the infection in relation to age and marital status, as a low prevalent rate was observed in children (23.0%) than in adults (57.4%) and there was a slight increase in the infection among married couples (56.5%) than in unmarried class (40.3%). The prevalence of H. pylori infection in the study centers calls for routine screening of blood for health education to enlighten the populace on the risk factors associated with the infection.

Abstract: The aim of this paper is to emphasize the use of genetic engineering to improve the oil quality in oilseed crops. Genetic engineering is a powerful tool to enhance the nutritive values of oilseed crops. Naturally the nutrition decreases due to constant growing of the different crops on the same land. The need is to adopt modern techniques that are less time consuming and give the best results. Different genetic engineering techniques like hairpin mediated transformation, gene silencing, Agrobacterium mediated transformation, somatic hybridization are very helpful in transforming the genetic makeup according to our own need. Plant oils are considered beneficial when the level of Erucic acid and Glucosinolates is low. This becomes possible through adopting the modern techniques of genetic engineering. Major oilseed crops like cotton, canola, soybean, sunflower need few genetic modifications to enhance their oil quality. The main concern is to introduce such genes which can add to its value. Through the help of biotechnology, we are able to decrease the gossypol level in cotton seeds and not in the leaves which is the remarkable work of biotechnology. Tph1, tph2 and o1 genes are introduced in sunflower to enhance Tocopherol level, which is useful to maintain oil stability. Such as LPAT gene introduction in soybean helps to enhance oil contents. Increase in soybean biodiesel production is also achieved by genetic engineering. Gene silencing also plays a major role to enhance stability of oils by minimizing linolenic acid level.

Abstract: This study evaluated the antimicrobial activities of crude ethanolic and aqueous extracts of Aloe vera using standard techniques. Results obtained revealed reasonable antimicrobial activities on the tested organisms to varying zones of inhibition. The activities however were found to be concentration dependent while no apparent statistical disparity was observed with the different extracting solvents (tvalue = 0.88, p>0.05). The minimum inhibitory dilution of both extracts range from 25-100mg/ml. It can thus be inferred that the tested Aloe vera has good antimicrobial properties.

Abstract: The critique of research studies is an essential process that helps us in the synthesis of knowledge to use it in conducting new research or to use in practice. In the current paper, author critiques a qualitative research entitled “Relatives’ involvement in nursing care: A qualitative study describing critical care nurses” (Engstrom, Uusitalo, & Engstrom, 2011) for educational purposes. There are many benefits of research critique includes but not limited to broaden understanding of studies carried by scholars, summarize knowledge for using in practice, provide a knowledge base to conduct a new study and to determine the strengths and limitations of a qualitative research study. The following critique will be guided through criteria which are presented at the end of the article.

Abstract: Aquatic plants are considered nuisances when excessive growth interferes with desired water uses, including human health. The establishment of Aswan High Dam in the southern part of the River Nile in Egypt has many side effects. The aquatic macrophyte vegetation is growing so rapidly and densely that it represents an acute problem. The problems created by the hydrophytes are many such as, constituting a health hazard by providing mosquitoes larvae with an ideal breeding place, causing oxygen depletion, interfering with navigation, obstructing drainage and flow of water in irrigation canals, decreasing phytoplankton production, polluting water supplies, increasing sedimentation by trapping silt particles and causing loss of water through evapotranspiration and decrease the hydraulic efficiency of open channels infested by aquatic weeds. There are four main methods used to control aquatic weeds, in addition integrated weed control: manual methods; mechanical method; physical method; biological method and Integrated weed control. The objective of this paper is to present the Egyptian Experience that was gained through researches in order to be implemented in the field of control aquatic weed by using biological method (grass carp).

Abstract: Background: Contrast-induced acute kidney injury (CI-AKI) is a complex syndrome of acute renal failure occurring after the administration of iodinated contrast media. Patients with diabetes mellitus often require coronary angiography and coronary intervention and are at risk of CI-AKI. The small changes in serum creatinine (SCr) may be associated with poor outcomes and severe AKI so the performance of urinary L-FABP which is a 14-kDa protein expressed in proximal tubular epithelial cells as an early detection marker of CI-AKI has shown promise in various clinical settings. We tested the hypothesis whether L-FABP could represent an early biomarker of CIN in diabetic patients with normal serum creatinine undergoing cardiac catheterization in comparison with non-diabetic patients. Objective: The aim of this study is to prospectively assess specificity and sensitivity of L-FABP as a renal biomarker for quick detection of contrast induced nephropathy in diabetic and non-diabetic patients scheduled for coronary angiography. Methods: The present study was conducted on 84 patients admitted to Al-Taiseir international hospital with coronary artery disease and subjected to coronary angiography in cardiac catheterization unit. Patients classified into two groups diabetic and non-diabetic and then sub classified according to the RIFLE criteria on a day-to-day basis according to their worst creatinine and/or lowest urine output. Risk factors were evaluated for CIN, including: Patients with diabetes mellitus, hypertensions, dyslipidemia and ischemic heart disease. The L-FABP was studied for early prediction of acute kidney injury before and after coronary angiography. Results: After coronary angiography mean serum creatinine was increased (p value < 0.006). The mean creatinine clearance was reduced in our patients after usage of contrast (p value < 0.000). Mean L-FABP significantly increased 4 hours after coronary angiography and the sensitivity of L-FABP to CIN is 86% while specificity is 93% (with an AUC-ROC of 0.95) without significant difference in diabetic and non-diabetic groups. Conclusion: This study showed the importance of urinary L-FABP levels in quick detection of AKI associated with contrast administration earlier than serum creatinine after coronary angiography with similar prevalence of CIN in diabetic and non-diabetic patients. The sensitivity of L-FABP to CIN is 86% and specificity is 93%.
