The study was undertaken to assess the dosage-mortality ratio and toxic effects of Piper guineense fruit extracts on the adults of Biomphalaria pfeifferi, the snail intermediate host of Schistosoma mansoni, which causes intestinal schistosomiasis. The result showed significant toxic effects with crude ethanol and hot water fruits extracts. The estimated lethal dose concentration by arithmetic m...

Purpose To investigate whether the subcellular distribution of endocannabinoid (eCB) system (ECS) components in growing RGC axons is consistent with the formation of eCB-enriched "hotspots" and the role of the ECS in RGC axonal growth. Methods We used immunocytochemistry and image analysis to quantify axonal expression of the ECS components diacylglycerol lipase alpha (DGLα), monoacylglycerol...

An in vitro method was developed for high frequency shoot regeneration and continuous production of Brassica napus L. in large number. The different concentrations of benzyladenine (1.5, 3.0 and 4.5 mgl and thidiazuron (0, 0.15 and 0.30 mgl) were evaluated for shoot and root regeneration using hypocotyl explants with 7, 14 and 21 days old. Shoot regeneration (SR) was affected by both benzyladen...

Yolk-sac fry of Goldfish (Carassius auratus gibelio) were exposed to various concentrations of Al and pH for 3, 7 and 10 days. In this study number of dead fish, total length of larvae, yolk sac length, swimming activity, the number of gill cover movements and the number of heart beat was measured. The lowest and highest number of gill cover movements belong to the waters containing 50 mg L-1 o...

The objective of this study was to determine how alternative on-site wastewater treatment systems (i.e. subsurface flow constructed wetlands, intermittent sand filters and intermittent peat filters) affect the viability and culturability of Salmonella choleraesuis (serotype typhimurium, ATCC 23567). Influent was a high strength septic tank effluent (BOD5 240-344 mgL(-1), TN approximately 100 mg...

This study shows that a short-term respirometric measurement based on the rate of oxygen uptake needed to oxidize glucose is a reliable and fast method to assess biocide efficacy against P. fluorescens cells. Respiratory activity using oxygen consumption rate, the determination of viable and nonviable cells using Live/Dead BacLight kit and colony formation units (CFU), were compared as indicato...

C-type lectin receptors (CLRs) on antigen-presenting cells (APCs) facilitate uptake of carbohydrate antigens for antigen presentation, modulating the immune response in infection, homeostasis, autoimmunity, allergy, and cancer. In this review, we focus on the role of the macrophage galactose type C-type lectin (MGL) in the immune response against self-antigens, pathogens, and tumor associated a...

Adult-onset Still's disease (AOSD) is a multisystem inflammatory disease of unknown etiology. It is characterized by arthritis, hectic fever, transient rash and visceral lesions such as pleuropericarditis, lymphadenopathy and hepato splenomegaly. Although kidney involvement may appear in some cases of AOSD, minimal glomerular lesion (MGL) has not been described. We describe a female patient, wh...

an investigation was made to study the residual activity and air-borne effect of lambdacyhalothrin (icon 10 wp) at 30, 40 and 50 a.i. mg/rn2 against an.stephensi in hut scale trials on different surfaces in mamasani, and rudan, south of iran. bio-assay contact mortality test with icon at 30 a.i. mgl/m2 on plaster, cement and wood surfaces decreased from 100% to 51.4%, 53% and 63.8% after 84, 80...
