Abstract: Background: Osteoporosis is a progressive disease that has physical and psychosocial consequences,it is the most common bone disease in humans, it occurs accompanying menopause and induces bone loss. Therefore, the objective of this study was to assess associations between exercise training, vitamin K supplementation and vitamin D supplementation either alone or in combinations on the prevention of osteoporosis in ovariectomized rats, and to find the best combination that gives the highest treatment of osteoporosis. Methods: eighty ovariectomized rats with an average weight of 150 g were used in this study. They were equally divided into eight groups. Group I Sedentary control ovariectomized group (n=40). This group was further subdivided into 4 subgroups I a, I b, I c and I d. Group II Exercise group (n=40): This group was further subdivided into 4 subgroups II a, II b, II c and II d. Blood samples were taken from all groups. We investigated the circulating concentrations of Osteocalcin (Oc), Bone specific alkaline phosphatase (BSAP), Undercarboxylated osteocalcin (UnOc) and Serum Tartrate resistant acid phosphatase iso-enzyme 5b (TRAP5b). Results: Exercise trainings in overiectomized adult rats induced significant increase in Oc and significant decrease in UnOc and TRAP5b. Vit K alone produce significant decrease in UnOc and TRAP5b while Vit K with exercise produced significant increase in BSAP and significant decrease in UnOc and TRAP5b. Vit D alone produced significant decrease in TRAP5b while Vit D with exercise produced significant increase in Oc and BSAP with significant decrease in UnOc and TRAP5b. Combind Vit K with Vit D without exercise produced significant increase in BSAP and significant decrease in UnOc and TRAP5b while combined Vit K, Vit D with exercise produced significant increase in Oc and BSAP and significant decrease in UnOc and TRAP5b.Conclusions: Exercise has a great role in the treatment of osteoporosis that is mainly due to increased bone formation together with mild decrease in bone resorption so that the combination of exercise training with vitamin K and /or D supplementation was beneficial in the treatment of osteoporosis as they augment the effect of each other through combining increased bone formation with decreased bone resorption.

Abstra­ct: This work aims to study the effect of using soil conditioner (shale 10 Ton ⁄Fed), soil mulching (Rice straw) and plant foliar antitranspiration (kaolin 6℅) on water conservation for soil and plant. A pot experiment was conducted during 2012 and 2013 summer seasons by using calcareous soil from Noubaria region. Soil moisture content was adjusted at field capacity during the experiment. The treatments used  were control, kaolin(K), Rice straw(RS), shale(S) as a single treatments and, kaolin with Rice straw(K+RS), kaolin  with  shale(K+S) ,shale with Rice straw(S+RS) as a double treatments ,finally, kaolin  with Rice straw and shale (K+RS +S)as a triple treatment .Corn as indicator  plant was harvested after 90 days from planting. Soil evaporation, soil moisture retention  and plant transpiration was controlled   by using Rice straw ,shale and kaolin ,respectively as a commercial and economical  materials. Results showed that shale treatment (S) led to a significant increase in W.H.C℅, F.C℅, W.P℅ and A.W ℅ than kaolin (K), Rice straw (RS) and control treatments. Also, shale and Rice straw (S+RS) treatment showed a pronounced increase in all soil moisture constant studied than the other applied treatments (K+RS) and (K+S). Highest values for W.H.C℅, F.C℅, W.P ℅ and A.W ℅ were obtained by using (K+RS+S) treatment. Also, shale treatment was decrease water consumptive use (W.C.U) values from 7.18 L/pot for control treatment to 7.05 L/pot. Consequently, shale (S) increased water use efficiency (W.U.E) values more than kaolin (K) and Rice straw (RS) treatment from 1.22gm/L for control to 1.42gm/L due to high soil moisture retention of shale. Also data for (S+RS) treatment was more effective in increasing (W.U.E) values than (K+RS) and (K+S) treatments. Concerning the (K+RS+S) treatment a higher increase was obtained in W.U.E value and higher decrease in W.C.U was observed than all other experimental treatments used in this study. Whereas, the relative increase percentage of W.U.E over control for (K+RS+S) reached to 36.07℅. These results showed an important use of kaolin, shale and Rice straw as a commercial and economical materials in controlling water for soil and plant.

Abstract: In recent years, development in next to skin compression active sportswear fabrics has been progressing to perform high functions and achieve comfort. The main purpose of this study was to produce adequate fabric to be used in compression sport fabrics. Woven technique was applied to produce fabrics under study using different constructions (regular hopsack 2/2, twill 1/3, satin 4 and double weave) with warp sets of 80,100 and 120 ends/cm and weft sets of 75,100 and 125 picks/cm. Two textile materials were also employed; Lycra covered with polyester of 50 and 70 denier for warp yarns and textured polyester of 60 detex for weft yarns. Different parameters were studied including fabric structure, warp and weft set and yarn count and their influence on the performance of the end-use fabrics were also studied. On the other hand physical properties including; air permeability, water permeability tensile strength and elongation, abrasion resistance, thickness and weight, were evaluated according to the final product needs. The results demonstrated that some properties such as air and water vapor permeability,   abrasion resistance, thickness and weight are influenced by both material type and structure parameters.

Abstract: Modern agricultural practices are mostly directed toward high application of commercial fertilizers to achieve high yield. It is widely recognized that application of fertilizer (especially nitrogen) can cause ground water pollution by nitrate leaching through the soil profile. A new approach to farming is often referred to as sustainable agriculture and it seeks to introduce friendlier agricultural practices to the environment and maintains the long term ecological balance of the soil ecosystem. Hence investigations were carried out to develop nutrient management for strawberry cultivar Sweet Charley subjected to various treatment combinations of organic and inorganic fertilizers. Traits such as plant growth characteristics (leaves/plant and plant spread), yield characteristics (flower buds, fruits per plant and fruit yield tons/ha) and quality characteristics (juice content, total sugar content, vitamin C and specific gravity) were observed. The runners of strawberry cv. Sweet Charley were planted in the first week of November with a spacing of (30x60cm).The investigations was laid out in a randomized block design with five treatment combinations replicated thrice. The data regarding the different growth parameters observed at 30, 45, 60, 90, 105, 120 days after planting, yield parameters at 45, 60, 90, 120, 135, 150 days after planting and their quality parameters clearly indicate that the application of integrated sources of nutrients significantly affect the vegetative, reproductive and yield characteristics of the strawberry plant. However the manure fertilizer combination under treatment T4 (75% Organic Fertilizers + 25% inorganic Fertilizers) was found to be the best treatment with regard to integrated and combined application of nutrient resources for strawberry cultivation in India.

Abstract: Background: The purpose of this study is to determine the prevalence and risk factors of corneal graft rejection in patients undergoing corneal transplant in Imam Hussain (AS) hospital over the years 2009-2013. Materials and Methods: Patient inclusion criteria were: 1) corneal transplant in Imam Hussain (AS), Tehran, 2) received transplants during 2009-2013, 3) two-year track record in the patient's record. Patient exclusion criteria were: 1) incomplete record, 2) lack of patient follow-up, 3) using systemic immunosuppressive drugs. Information extracted from the records was used for statistical analysis. Results: In this study, a total of 215 cases of corneal transplantation were evaluated in 215 patients; mean age of patients was 49 years. The patients were followed for 24 months. Regraft (P<0.01) and anterior synechiae (P=0.009) are a risk factor for graft rejection. No significant relationship was found between irritating sutures (P=0.067); corneal vascularization (P=0.111); uncontrolled intraocular pressure (P=0.120); recurrent herpetic keratitis (P=0.134); transplantation accompanied to cataract surgery (P=0.186) and recipient age (P=0.283) and an increased likelihood of rejection. Conclusion: This study shows that regraft and anterior synechiae may increase the likelihood of graft rejection. There is no significant relationship between irritating sutures, corneal vascularization, uncontrolled intraocular pressure, recurrent herpetic keratitis, transplantation accompanied to cataract surgery and recipient age and increased likelihood of graft rejection.

Abstract: Maize (Zea mays), yellow variety was processed into ogi. Two methods of processing were used to process the Ogi paste, Sieving and unsieving methods. The sieved ogi and the unsieved ogi were shared into four each. One part was fortified with soybean paste alone, 2nd part was fortified with soybean and spices (ginger and clove), the 3rd part was fortified with spices alone while the 4th part was left plain (unfortified). The ogi mixtures were dried and milled to powder. The proximate composition and mineral contents of the ogi samples were determined. The ogi samples were also evaluated organoleptionally. There was no significant difference p<0.05 in the moisture content of all the ogi samples fortified with soybean paste and spices. Crude protein ranged from 9.22% in the sieved plain Ogi to 14.56% in the unsieved soy ogi + spices. The fat contents of all the ogi samples were significantly different at p<0.05. Unsieved soy ogi sample contained the highest fibre (8.26%), fat 9.07%, but the least carbohyderate (58.17%). Unsieved soy ogi + spices also recorded the highest value for sodium (61.08 mg/100g), calcium (90.28mg/100g) and magnesium (152.32mg/100g). There was no significant difference p<0.05 in the iron (Fe) contents of all the spiced ogi samples. Sieved plain ogi recorded the least value for sodium (34.24mg/100g). All the ogi samples compared favourably well in terms of sensory quality. Fortification of plain Ogi from maize with soybean and spices improved the nutrient composition of Ogi. Nutrients are better retained in the unsieved soy ogi samples.

Abstract: Background: different structures of health care and treatment have different types of activity and different impact on their performance. Objectives: identification and comparison of organizational culture prevailing in city health-care center with public hospitals in the city of Amol. Methods: This cross-sectional comparative study was carried out in health care center and public hospitals of the city of Amol in 2012. 300 subjects from the hospitals and 95 persons from health-care center were completed Denison standard questionnaires as self-report. Exclusion criteria were nontechnical support personnel of services, transportation, logistics and physical protection. Data collected were analyzed using Spearman's, Kendal's, Kruskal Wallis's, Mann-Whitney's and chi-square tests (p<0.05). Results: In health-care center, the highest average was related to Mission culture = 2.99, SD = 0.53) and in hospitals, it was found for Involvement = 3.25, SD = 0.51) and Adaptability was found the lowest average in the both systems. The health-care center tends towards stability- external focus and hospital tends towards internal focus, although the tendency was towards greater stability, but no significant differences were found. Conclusion: the treatment system has higher components of organizational culture than health care system. But in the both system it seems that Adaptability culture requires more attention of administrators.

Abstract: Background: Pituitary tumors are usually soft creamy and succable. Fibrous adenomas are tough and firm and more difficult to remove. Their incidence among pituitary tumors is 5% -13.5%. Fibrous adenomas contain more abundant collagen and reticulin. MRI can predict firm and fibrous adenomas in that, the tumor is isointense in T2-WI and homogeneously enhancing in T1WI. The problem of such a tumor is how to excise it safely with preservation of neurovascular structures and normal pituitary function. Material and methods: Among 45 cases of pituitary adenoma operated upon over 3 years (2011-2013), 10cases found firm and fibrous. Six cases had been operated upon by microscopic transsphenoidal approach and 4 cases operated by endoscopic transsphenoidal approach. Five cases in whom we failed to achieve proper resection and decompression; they had been reoperated in a second surgical setting either by microscopic transsphenoidal or transcranial pterional approach. A third surgical transcranial setting done for one patient aiming at achieving proper decompression and preserving visual function. Results: Partial tumor resection achieved in 7 patients and subtotal resection achieved in 3 patients. Complications included major vascular injury in one patient, temporary diabetes insipidus in two patients, and CSF rhinorrhea in one patient that ceased with lumbar drainage without patching. Conclusions: Preoperative prediction of firm and fibrous pituitary adenoma is of great value for the surgeon to plan the surgical strategy. MRI is the modality of choice in that way. The endoscopic transsphenoidal approach is safe, minimally invasive, and efficient surgical technique for partial tumor resection. Extended endonasal endoscopic approach offers a potentially viable treatment option. Microscopic transsphenoidal surgery is properly effective but may require multi-staged operation. Long sized and small calibered ultrasonic aspirator applicable to the transsphenoidal approach must be used to optimize the surgical technique. Transcranial approach should be reserved for eccentric tumors and for cases that failed to be properly managed by the transsphenoidal route.

Abstract: Helicobacter pylori (H. pylori) is one of the most common chronic bacterial infections in developing countries. H. pylori infection has been established firmly with the development of gastric neoplasia, including gastric adenocarcinoma and gastric mucosaassociated lymphoid tissue lymphomas. The aim of this study was to investigate the seroprevalence of Helicobacter pylori infection in symptomatic patients and to determine the relationship between H. pylori and ABO/Rhesus blood groups, age, gender, socio-economic status and smoking in Tripoli, Libya, using three different commercial serological test methods. One hundred patients from Alhanan Specialized Medical Clinic in Tripoli were included in the study. A total of 100 samples were collected from these patients undergo serologic testing for the presence of anti–H pylori antibodies in serum or whole blood. Results revealed that by using (ABON test method) antibodies were seen in 36% of the patients and 29% by using ADVANCE QUALTY test method and 35% in (Helicobacter pylori IgG Enzyme immunoassay test method) which was nearly similar to the result obtained by ABON test. We found that the seroprevalence of H. pylori infection was not significantly associated with ABO blood groups, age, sex, occupation, socioeconomic condition and smoking (P- value > 0.05).

Abstract: Responses of Chrysichthys furcatus to glyphoste formulation and Garcinia kola seeds extracts was investigated using organization for Economic Cooperation and Development #203 and #407 recommended toxicity bioassay. The fish were divided into five groups and exposed to different treatments of glyphosate formulation and Garcinia kola seed extract, with control serving as a reference. The fish were divided into five groups of five juveniles per test concentration in three replicates. Group A was given de-chlorinated water. Group B was treated with 0.16mg/L glyphosate formulation only while other groups were exposed to the same concentration as in group A, but with different concentrations of Garcinia kola extract. Group C, D and E received 150, 250, and 350mg/L of extract of Garcinia kola seeds respectively. There was no significant different (p > 0.05) between fish treated with glyphosate formulation alone and other treatments except dissolve oxygen which was highly significantly (p < 0.01) between fish treated with glyphosate formulation alone and other treatments and the control. All the blood parameters were significantly (p < 0.05) affected by glyphosate formulation when compared with the control. The changes observed in glyphosate formulation alone were reversible when G. kola seeds extract were added, and was dose dependent. The plant’s extract has shown to be a good remedy to pollutants, and formulations of the seed extract into tablets or capsules could serve as antidote to ameliorate the effects of pollutants. This finding can reduce the risk of biomagnifications of poisons along the food chain.

Abstract: Magnetic water is considered one of several physical factors affects plant growth and development. Magnetic water fields are known to induce biochemical changes and could be used as a stimulator for growth related reactions. The seeds of broad bean (Vicia faba, L. cv. Giza 3) were irrigated with water passed through magnetic device (Magnetic Funnel - MAGNETIC TECHNOLOGIES DUBAI, UAE, LLC. FATENT No. 1826921). Two pot experiments were conducted during season 2010-2011 at greenhouse to study the impact of magnetized water on growth, some chemical constituents and yield productivity of broad bean plants. Magnetic water increased leaf area than that the tap water (control). The stimulatory impact of magnetic water may be ascribed to the increasing of plant growth (plant height, leaf area, leaves, stems, roots fresh and dry weights) and yield production, which increase absorption and assimilation of nutrients. It appears that irrigation with magnetic water may be considered a promising technique to improving the growth and water content of broad bean plant. Magnetic water treatment could be used to enhance growth, chemical constituents (chlorophyll a and b, carotenoids, total available carbohydrates, protein, total amino acids, proline contents, total indole, total phenol, GA3, kinetin, RNA, DNA,) and inorganic minerals (K+, Na+, Ca+2 and P+3) contents in all parts of broad bean plant under greenhouse condition. Results indicated that, irrigation with magnetic water induced positive significant effect on all studied parameters.

Abstract: Backgrounds and aim of the work: Diabetic neuropathy is the most common complication of diabetes mellitus (DM). Diabetic peripheral neuropathy involves the presence of symptoms or signs of peripheral nerve dysfunction in people with diabetes. The aim of this study was to assess the level of oxidative stress markers in patients with type 2 diabetes with peripheral neuropathy in compared to healthy subjects. Subjects & methods: The study was performed on 100 outpatients with type 2 diabetes matched with Age, BMI and Gender with 25 healthy subjects was selected from the outpatient’s clinics of National Institute for Diabetes and Endocrinology. All groups were subjected to estimation of Fasting blood glucose, Glycosylated haemoglobin (HbA1c) and lipid profile in addition to ox-LDL, LPO and TAOS (TAC). Results: Fasting blood glucose and HbA1c showed significant increase in the diabetic patients groups compared to control group (P˂0.05). Serum total cholesterol, Triacylglycerol and LDL-c were significantly higher in diabetic patients groups as compared to control group (P˂0.05) while HDL-c level showed significant increase in the control group when compared to diabetic patients groups. The level of ox-LDL and LPO represented significant increase (P˂0.0001) in the diabetic groups comparison to control group, while the level of TAOS (TAC) represented significant elevation (P˂0.0001) in the control group in comparison to the diabetic groups.

Abstract: Human beings for a long time receive influence by the color of environment and were sensitive to it, but use it in various fields. In addition to color communication and messaging is a significant and important role in various communities as a symbol of emotional, cultural, ethnic or national has been used. Human beings were physically or psychologically affected by the colors. It is obvious that the human impact of color and indirectly psychological aspects of norms, reaction, reactions and behaviors of individuals. For example, in Colgate toothpaste hologram and metallic color makes the customer have more than Procter & Gamble (singh, 2006). Nineteenth century, extensive theoretical developments in the field of color, but the results of the discoveries of the twentieth century have been a period. Despite the wide spread use of color was after World War II, but people understand that access to color, style alters our understanding of the reactions were many miles away (Karkya, 1996). With all the colors and the details of our lives are so closely, that is to say the colors are like steps that people with physical and mental phenomena of the universe in relation to other components. This article is based on the following assumptions seem that the role and function of the dynamics and increased efficiency in the color of lead and seeks to answer the question of whether there is at least one of the art information and artistic concepts that managers can increase the working efficiency of the organization or not?

Abstract: Age specific variations in mating, fecundity and reproductive performance occur in many organisms. Drosophila melanogaster represents a good model system for age-related studies and testing direct fitness benefits gained when females mate with specific male phenotypes. However, how male age related changes in male accessory glands and fitness traits are affected by rearing temperatures, has not been examined. Here we examined age-related mating of D. melanogaster in three age classes reared at three different temperatures. In all the rearing temperatures, young males with larger accessory glands containing a small number of large cells produced greater quantity of Acps than old males. Furthermore, young males transferred a greater quantity of Acps and sperms to mated females and as a result females that mated with young males produced significantly greater number of eggs and sperms than female mated with old males. This result was found to be similar in all the three temperatures in D. melanogaster. Together our data indicate that male age related changes in the accessory gland and sperm traits are independent of rearing temperatures.

Abstract: This paper aims at studying the effect of the previous knowledge about the studied courses in the success of the student in Faculty of Sciences and Humanities (Thadiq) -Shaqraa University-KSA. The Logistic Regression (LR) was used to analyze the data. The important result was, there is significant relationship between the success of the student in the studied courses and the previous knowledge about these courses. Nearly 95% of the success of the students returned to the previous knowledge about the studied courses. In consequence of the above mentioned results, there are two discussions: The first is to conduct similar studies to other courses in the other faculties, and the second is to take the advantages of this study in the planning and improvement of success proportion.
