Abstract: The purpose of this study is to determine the correlation between parathyroid hormone (PTH) and body mass index (BMI) on the overall stability index (OSI) in Saudi males with vitamin D deficiency. Method: A total of 669 adult Saudi males with mean age of 19.9 years suffering from vitamin D deficiency were participated in this study. The subjects were divided according to their PTH status into two groups; group 1 (n=619) having a normal PTH values; and group 2 (n=50) suffering from hyperparathyroidism. Participants were also categorized based on their BMI into; underweight (BMI<17.9), normal (BMI=18-24.9), overweight (BMI 25-29.9), and obese (BMI>30). The OSI protocol was used to compare vitamin D deficiency subjects’ that having normal PTH values with those suffering from hyperparathyroidism for different BMI categories. The Biodex Balance System was used to measure the OSI values. Results: No significant differences were observed between normal and high PTH groups in age, weight, height, BMI, OSI, vitamin D, calcium, phosphorus, and alkaline phosphatase. A significant positive correlation between OSI and PTH (r=0.135, P=0.011) was perceived. The results also revealed that the BMI had a significant positive association with OSI (r=0.521, P<0.001). In addition, BMI had positive correlation with PTH (r=0.109, P=0.042). The highest average OSI value was observed in the subjects having both obesity and hyperparathyroidism. Conclusion: The PTH and BMI have a positive correlation with OSI, which means that hyperparathyroidism and obesity synergistically increase the risk of falling in Saudi males with vitamin D deficiency.

Abstract: Dental anomalies can occur either in the size, shape, number or composition of the teeth. They are caused by disturbance during any stage of teeth development, but the exact etiology is unknown. They are more frequent in children with clefts especially supernumerary teeth and the double teeth. The aim: of this report is to document a case that represents geminated primary upper incisor with the presence of supernumerary tooth in primary dentition. Methods: A four years, six months old male presented in dental clinic in Batterjee Medical College of Science and Technology in Jeddah, Saudi Arabia.. His Chief complain was pain and pus in his anterior teeth. Two bitewing radiographs were taken which revealed a double tooth (geminate) with one root and one radicular pulp (pulp chamber) with supernumerary tooth apical to the double tooth. The double tooth was extracted (tooth number # 61), along with the supernumerary tooth (#62). Conclusion: Although the case of geminated tooth was associated with supernumerary tooth, no other anomalies like clefts was reported.

Abstract: The ethanolic extract of the aerial parts of Markhamiazanzibarica (Bignoniaceae) was tested for its cytotoxic activity against human cervical adenocarcinoma cell line (HeLa). It showed a potent effect with an IC50 of 9.68 g/ml compared to Doxorubicin (7.28 g/ml). The fractions obtained from the successive partitioning of the total extract, were tested against the same cell line; the results revealed that n-hexane extract was the most potent 9.23 μg/ml, followed by ethyl acetate, butanol and chloroform fractions with IC50 of 21.2, 22.4 and 49.6 g/ml, respectively. Column chromatography led to the isolation of oleanolic acid (1), ursolic acid (2) and luteolin (3). The structures of the isolated compounds were elucidated using spectroscopic techniques.

Abstract: Objectives: This study was conducted to evaluate current performance of community pharmacists and provided services in community pharmacies in Jeddah to praise the necessary changes in order to meet international standards. Method: A questionnaire composed of six sections (total of forty-eight questions) centered on the pharmacist and the pharmacy itself was randomly distributed to 99 pharmacies in Jeddah that was divided into four regions (North, South, East, and Middle-West). Results: Ninety-five out of ninety-nine pharmacists have a bachelor degree; all of them were non-Saudi males. The average number of pharmacists in each pharmacy during working hours was 1-2(86%) of pharmacies. Seventy-one percent were aware of the ADR reporting program. Twenty-nine percent dispense prescribed medication without a prescription; 57% deals with trade names. Eighty-seven percent of pharmacists claimed that they provide patient counseling; seventy-eight percent deal with medication errors. Fifty tow percent don't communicate with doctors. Only 37% of pharmacies have a website while 8% of them provide online services and delivery. Twenty-five percent of pharmacists provide educational programs for chronic disease. Sixty for percent of pharmacists claimed to have enough training and supervision from their administrations and only 6% showed no interest in getting more information on current pharmacy practice and new drugs. Conclusion: After evaluating the pharmacists working in community pharmacies and the services provided, this study has proved that many important services were lacking and that development in necessary in order to meet the international standards of pharmacy practice.

Abstract: In this thesis a series of novel 4-substituted quinazoline derivatives was rationally designed, synthesized and biologically evaluated for their anticancer activity. The sixteen synthesized compounds IVa-f, Va-d, VIa-d and VIIa, b were evaluated for their antitumor activity against MCF7 and HEPG2 cell lines at National Cancer Institute (NCI, Egypt). Eight of these compounds IVc, IVf, Vc, VIa-d, VIIb were selected due to their promising activity against the cell lines to be tested in vitro against VEGFR2 inhibition in KINEXUS cooperation, Canada. Compound VIa show marked inhibitory activity against VEGFR2 (52%). The obtained results were clarified using molecular modeling study using grid-based ligand docking with energetics glide program. The design depends on exploration of the previous revealed SAR studies, identification of the key interactions with the binding site and bioisosteric modifications of the reference compound 6.

Abstract: ABO and rhesus (Rh) blood group antigens are the most frequently studied genetic markers in a large group of people. The knowledge of the distribution of ABO and Rh blood groups is essential for effective management of blood banks inventory, be it a facility of smaller local transfusion service or a regional or national transfusion service. Apart from the importance in blood transfusion practice, the ABO and Rh blood groups are useful in population genetic studies, researching population migration patterns as well as resolving certain medico-legal issues, particularly of disputed parentage. The present study was done to assess the prevalence of blood groups in different categories in Jeddah province and to compare our results with other studies conducted in KSA and elsewhere in the world and its multipurpose future utilities for the health planners. In our study, Determined the ABO group and Rh blood group for 800 Saudi population. The participants for this study were the blood donors coming to King Abdul Aziz hospital (KAAH) blood bank, in the period of November, December 2015, and January2016. They were from different ages and from numerous and diverse national and cultural backgrounds, who either donate blood regularly or to cover hospital needs. The overall distribution of blood group in our sample study was 53%, 24%, 18%, 6% for groups O, A, B, and AB respectively. While the prevalence of Rh (D-antigen) blood typing was 91% Rh positive and the remaining 9% was Rh negative.

Abstract: Background: The differentiation of benign from malignant follicular thyroid neoplasms remains difficult and some controversial results have been reported for the immunohistochemical markers of malignancy proposed so far. Nodular tumors exhibiting a predominantly follicular architecture are the most common presenting and confusing pattern of thyroid neoplasms. They can be benign as follicular adenoma (FA) or malignant as papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC). Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Material and methods: This study was carried out on 176 thyroid specimens received as paraffin blocks (84 FA, 50 PTC and 42 FTC) using three markers HBME-1, CITED-1 and FN-1. Results: All three markers combined were positive in 23 malignant cases with no combined positivity in the benign cases. CITED-1 was positively expressed in 65 malignant thyroid lesions (50 PTC and 15 FTC). HBME-1 was positive in 58 malignant cases (46 PTC and 12 FTC). FN-1 was positive in 52 malignant cases (46 PTC and 6 FTC). At least for 2 positive markers, regardless of which two, the sensitivity for the detection of malignancy was 58.7% with 100% specificity while single marker immunoreactivity increased sensitivity but markedly reduced specificity. CITED-1, HBME-1 and FN-1 expression was statistically significant in PTC cases than their expression in FTC. Conclusions: A panel of HBME-1, CITED-1 and FN-1 can be a useful tool for differentiation between benign and malignant follicular thyroid neoplasms and probable distinguishing of PTC from FTC.

Abstract: Gamma ray, a mutagen used in crop and ornamental plant breeding, is expected to induce novel mutations. Therefore, this study aimed to investigate the effect of different doses of gamma-ray (Caesium-137) irradiation on the germination rate, plant height, and appropriate dose for causing boom in two varieties of local rice, namely, MRQ74 and MR269. Dry MRQ74 and MR269 seeds were irradiated at 0, 100, 200, 300, 400, 500, 600, and 700 Gy. Hydroponic germination under controlled conditions followed. The germination rate and the height of the plantlets were investigated as morphological responses. Consequently, compared with the control samples, the plantlets that were given low doses (0 and 100 Gy) showed an increase in height, whereas those given doses ranging from 200 to 500 Gy showed a reduction in germination rate and height. At doses exceeding 500 Gy, physiological damage on the seedling height became severe and none of the varieties survived. Doses between 340 and 360 Gy caused a 40% reduction in seedling height in MR269 and MRQ74. Doses between 351 and 365 Gy caused a LD50 dose in MR269 and MRQ74, respectively.

Abstract: Background: Nephrotoxicity induced by several synthetic drugs represents a major problem of modern population. Licorice Glycyrrhiza glabra L.is one of the most widely used herbal drugs around the world, being present in most pharmacopoeias of eastern and western countries. It exhibits many biological activities and possibly even has protective effects against chronic diseases. Aim: The present study was conducted to determine the protective effect of licorice extract against gentamicin-induced nephrotoxicity in male rats. Material and Methods: Forty male rats were divided into four groups as follow; (1): control group, (2): gentamicin (GM) group; rats injected intraperitioneally (i.p.) with GM at a dose of 100 mg /kg body weight (b.w.) for five consecutive days to induced nephrotoxicity, (3): licorice extract group; rats administered licorice extract daily at a dose of 150 mg/ kg b. w. via gavage, and (4) GM group pretreated with licorice extract; rats were orally received licorice extract at the same dose and route in group (3) up to seven days followed by injected i.p. with GM as in group (2). Separated serum samples were used for determination of kidney functions and ionic sodium (Na+) and potassium (K+). One kidney was used for estimation of lipid peroxides (MDA) and reduced glutathione (GSH), while the other kidney was examined histopathological. Results: GM injection induced marked nephrotoxicity as evidenced by significant elevation in serum levels of creatinine, urea, uric acid and K+, with significant reduction in serum levels of Na+. Antioxidant status in kidney tissues showed that, in GM there was significant increase in MDA with significant depletion in GSH activity as compared with control group. Pretreatment with licorice extract protected the rats from GM- induced nephrotoxicity as evidenced by significant improvement of these investigated parameters, with restore antioxidant status. Histological examination of renal tissues showed marked glomerular, vacuolations of the wall of blood vessels associated with necrobiotic changes in renal tubules in GM injected group, meanwhile there were amelioration in rats group received licorice extract pre-GM injection. Conclusion: Licorice extract exert potential antioxidant activity and offer nephroprotective effect against GM- induced nephrotoxicity in male rats.

Abstract: This paper investigates the impact of the following parameters on the structural behavior of horizontally curved bridge decks: 1- the analytical modeling methods; 2- the radius of curvature; 3- the number of internal cross girders and 4- the thickness of the deck slab. The results of the different analytical modeling technique are compared to experimental results by conducting a load test on a curved bridge deck physical model at the structural lab of the American University in Cairo. The remaining parameters of this study are investigated using a typical curved concrete slab-girder bridge deck which is commonly used in real projects. The impact of these parameters on the structural behavior of the deck is addressed by the change in straining actions and the deflection of the main girders of the bridges.
