Hence, it is concluded that the functional BDNF (Val66Met) and SERT (5'-HTTLPR) gene polymorphisms may not be associated with depression. Replication studies on these polymorphisms with large sample size are needed.Melittin (Mel), a natural detergent, is a major component of bee venom. Mel exhibits favorable clinical effects on the treatment of rheumatoid osteoarthritis, myositis, lumbar muscle strain, and peripheral neurological disorders. Interleukin-1β (IL-1β) contributes to the progression of osteoarthritis and is one of the key proinflammatory cytokines. However, the effect of Mel on IL-1β-induced osteoarthritis has not been reported. We examined the effects of Mel on the expressions of inducible NO synthase (iNOS), nuclear transcription factor κB (NF-κB), and I kappa B (I-κB) in the knee joint cells of C518 rats induced by IL-1β. Western blot and qPCR results showed that Mel at 0.1µg/mL or higher significantly inhibited iNOS expression. Similarly, 1µg/mL of Mel prevented IL-β-induced I-κB degradation in the cytoplasm and NF-κB migration from cytoplasm to nucleus. Mel exerts an inhibitory effect on IL-β-induced NF-κB activation by inhibiting both I-κB degradation and NF-κB migration and can potentially be developed as a new anti-osteoarthritis drug. Further research is needed to clarify the detailed mechanism.Extra-Intestinal Escherichia coli (ExPEC) are important cause of Urinary Tract Infections (UTIs) and systemic infections. The purpose of this study was to investigate numerous ExPEC bacterial isolates for phenotypic virulence characteristics including hemolytic activity and resistance pattern and to observe their association with genetic traits via Polymerase Chain Reaction (PCR). A total of 367 ExPEC isolates were collected from patients admitted in Khyber Teaching Hospital (KTH) Peshawar, Pakistan. Standard techniques were used for identification of isolates, determination of hemolytic potential and antimicrobial susceptibility testing. PCR was used for screening of virulence genes using specific primers. A total of 367 ExPEC isolates were characterized, among which 62.7, 24.3, 7.1 and 6% were isolated from urine, pus, sputum and wound specimens, respectively. Majority of the isolates (82.8%) were hemolysin positive. Multi drug resistance pattern was shown by 41% of the isolates and harbored at least one virulence gene (71.7%), of which sat was the most prevalent (64.3%). IκB inhibitor The highest resistance was found to cefotaxime (99.2%), ampicillin (97.5%) and aztreonem (89.6%). 15 different virulence genes combinations were observed in the current study. A total of 16 virotypes (15 of positive virulence genes and one of no virulence gene) were observed in the current study. The current investigation showed a high prevalence of sat and hlyA genes among ExPEC isolate, suggesting a role of these genes in the pathogenesis of ExPEC.Skin-whitening effect is closely linked with the melanogenesis inhibitory activity and free radical scavenging capacity. The purpose of the present study was to evaluate the skin-whitening effect of cumin (Cuminum cyminum L.) extract. The whitening activity was evaluated by cell-free mushroom tyrosinase assay, free radical scavenging assay, cell viability assay, cellular tyrosinase assay and melanin content assay using B16F10 murine melanoma cells. The results showed that cumin extract exhibited concentration-dependent inhibitory effect on both monophenolase and diphenolase activities of mushroom tyrosinase (IC50 values of 1.027mg/mL and 0.977mg/mL, respectively). Kinetic study on diphenolase showed that the cumin extract was a reversible mixed-type inhibitor, and the inhibition constant (KI) was determined to be 0.62mg/mL. In addition, cumin extract significantly suppressed melanin production and cellular tyrosinase activity of B16F10 melanoma cells in a concentration and time dependent manner without cytotoxicity. Moreover, cumin extract exerted strong scavenging capacity on DPPH, hydroxyl and superoxide anion radicals. Taken together, these results strongly suggest that cumin is a potential skin-whitening agent for the cosmetic industry.Present work investigates the effects of hydro-methanolic roots extract (HyMREt) of Rauwolfia serpentina in type 1 diabetic mice. Mice were divided into normal, diabetic, negative and positive controls (I-IV) and three test (HyMREt doses) groups (V-VII - 50, 100, &150mg/kg). Allocated treatment of each group was given orally for 14 days in overnight fasted state. Percent change in fasting blood glucose (FBG), body weights, body tissue weights, hepatic glycogen, total lipids, glycosylated hemoglobin (HbA1c), complete blood profile and antioxidant enzymes including catalase (CAT) and superoxide dismutase (SOD) were estimated. HyMREt doses produced meaningful (p less then 0.0001) reduction (-39 to -53%) in FBG. Hemoglobin (Hb) levels were raised, HbA1c were considerably decreased (4.5-3.77%) and glycosylation (HbA1c to Hb) ratio was expressively (p less then 0.0001) improved in test groups. Dose-wise improvement (p less then 0.05) in total glycogen and decrement (p less then 0.05) in lipids were observed in livers of test groups. HyMREt significantly decreased (p less then 0.05) percent inhibition of SOD and CAT. HyMREt doses progressively (p less then 0.05) improved RBC and other hematological parameters while decrement was only noticed in leucocyte counts. Administration of test doses of HyMREt were significantly reduced the glycosylation, oxidative stress and anemia caused by alloxan intoxication in mice.This study was designed to scrutinize the clinical effectiveness of intrathecal injection of medicine along with constant lumbar cistern drainage on intracranial infection subsequent to intracranial tumor operation. Sixty two patients with intracranial infection after intracranial tumor surgery were selected as the objects of study divided into combined treatment group (n=31) and the control group (n=31) according to the time of admission. Patients in the combined treatment group were treated with intrathecal injection of medicine combined with group's continuous lumbar cistern drainage while patients in the control group were just treated with intravenous antibiotic therapy followed by comparison in the clinical efficacy, infection control, the level of inflammatory factor like crp, IL-4 and incidence of complication in the two groups were compared respectively. The total effectiveness rate was 96.77% in the combined treatment group and 80.65% in the control group indicating statistical significant difference (p less then 0.
