    Objective: The purpose of the present study was to evaluate the possible association between the serum levels of undercarboxylated osteocalcin (ucOC) and osteoprotegerin (OPG) in patients with knee osteoarthritis (OA). Methods: Twenty patients (10 men and 10 women) diagnosed to have knee OA, and twenty healthy subjects of matching age, sex, and BMI as a control group, were enrolled in this study. Serum levels of ucOC and OPG, were assayed using the corresponding human ELISA kits. Results: Patients with knee OA, showed a statistically significant elevation in serum levels of ucOC (P<0.001), and a statistically significant reduction in that of OPG (P<0.0001), as compared to the control group. Also, there is significant negative correlation (r=-0.554, p= 0.0113) between the serum levels of ucOC and OPG in knee OA patients. Conclusion: there is possible association between the serum levels of ucOC and OPG in patients with knee OA

    Objective: The aim of the present study was to evaluate the effect of prophylactic inhibition of inducible nitric oxide synthase (iNOS) by aminoguanidine (AG) on serum levels of some adipocytokines in pristane-induced arthritis in rats.Methods: Forty white Albino rats were divided randomly into four groups; each group was composed of ten rats (five male and five female). Group I (AP) has received AG (100 mg/kg/day) i. p. for seven days, and then at day 8, has received single 150 µl pristane dose sc. at the base of rat's tail. Group II (PC) has only received single 150 µl pristane sc. at the base of rat's tail, at day 8 from the start of the experiment. Group III (AC) has only received AG (100 mg/kg/day)i. p. for seven days. Group VI (VC) has only received normal saline via i. p. injection for seven days. At the end of the experiment time, rats were sacrificed, and serum samples were obtained and used for the measurement of iNOS, rheumatoid factor (RF), c-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interleukine-6 (IL-6), leptin and adiponectin levels, using the corresponding rat ELISA kits.Results: Administration of pristane for the induction of RA has resulted in significant increase in all of the measured parameters in PC group as compared to VC and AC groups, except for iNOS where the increase was significant as compared to AC group only. Serum levels of RF, CRP and IL-6 in AP group have showed to be significantly elevated as compared to VC and AC groups. Administration of AG has resulted in different levels of reduction in all of the measured parameters in AP group as compared to PC group. The reduction was statistically significant with regard to CRP and leptin.Conclusion: prophylactic administration of the selective iNOS inhibitor AG, has resulted in a reduction in serum levels of the measured adipocytokines which may reflect a reduction in the severity of PIA.Â

    The aim of this cross sectional study was (1) to identify and compare the approaches which are used to care for carious primary molars between pediatric dentists (PDs) and general dental practitioners (GDPs) in Saudi Arabia and (2) to evaluate the knowledge level of the most appropriate treatment decisions for both groups with regard to caries in primary molars and its relation with demographic variables. A random sample of 600 GDPs and all registered PDs (n = 100) in the Saudi dental society in 2016 were emailed a two part questionnaire; the first part included questions about demographic data and the second part investigated knowledge of the participants of the most appropriate treatment decision in four hypothetical case scenarios in which the severity of caries in a single primary first molar differed. Data were analyzed using chi square and ordinal logistic regression statistical tests. The significance was set at 0.05. The average knowledge score was 1.28 for GDPs and 1.80 for PDs. There were significant differences between both groups on their choice of the most appropriate treatment option in three out of four scenarios. Two factors significantly improved the participants? knowledge; age and qualification (P<0.050.05). PDs were more interventionists, ready to perform pulpotomy and extraction in the absence of equally appropriate treatment options. GDPs and PDs in Saudi Arabia had different treatment approaches of different carious conditions affecting primary molars. PDs had moderate but significantly better knowledge of the most appropriate treatment option than GDPs

Media containing sucrose /yeast extract or glucose/ yeast extract were the most effective for lipid production from fungal, during  two weeks  incubation period, the highest biomass of dry weight was (19.6 , 18.8) g / L , (25.8 , 30.5) g /L  and  lipid yield (1, 0.97 )g/L, (0.65, 0.65) g/ L for two isolates Aspergillus terreus and Aspergillus fumigatus  respectively then followed maltose/ yeast extract then  starch / yeast extract .Analysis of fatty acid produced by two fungal isolates  using Gas Chromatography  showed the existence of a wide range of fatty acids, these fatty acids were together saturated and unsaturated. The results revealed that the unevenness in the fatty acids composition mainly depends on the type of carbon and nitrogen sources. The existence of saturated and mono saturated fatty acids in A.fumigatus, A. terreus prove that they are  good candidate for biodiesel production.
