BACKGROUND Androgen levels in the prostate may influence carcinogenesis in this organ. Inhibitors of the enzyme 5alpha-reductase block conversion of testosterone to the more active androgen dihydrotestosterone. The use of a 5alpha-reductase inhibitor, finasteride, in the chemoprevention of prostate cancer is being evaluated in a clinical trial. PURPOSE This study was conducted to determine if...

This study aims to determine the toxicity of formulated herbicide concentration non-target organisms (non-target) earthworms. The was conducted from April July 2021. design used a completely randomized (CRD) with nine (9) concentrations (K) treatments, namely: K0 = control, K1 200 ppm (0.2 ml/l water ), K2 400 (0.4 ml/ l water), K3 600 (0.6 K4 800 (0.8 K5 1000 (1.0 K6 1200 (1.2 K7 1400 (1.4 K8 ...

Although individual γ-Fe2O3 and α-Fe2O3 have been widely fabricated for gas sensors, their mixed phase of α/γ-Fe2O3 might deliver excellent sensing properties. In this study, a facile solvothermal method was used to fabricate Fe-alkoxide. After thermal treatment, it converted into γ-Fe2O3, mixed-phase with nanosheets-assembled flower-like structure. We studied the influence calcination temperat...

Three experiments were conducted to evaluate the efficacy of phosphorylated mannans (MAN) and pharmacological levels of ZnO on performance and immunity when added to nursery pig diets. Pigs (216 in each experiment), averaging 19 d of age and 6.2, 4.6, and 5.6 kg of BW in Exp. 1, 2, and 3, respectively, were blocked by BW in each experiment, and penned in groups of six. A lymphocyte blastogenesi...

acute toxicity test on common carp weighing 18 grams and length 12 cm was performed. with concentrations of 0, 2, 5, 10, 20, 40, 60, 80, 100, 200, 400, 600, 800 and 1000 ppm measured at 0, 24, 48 and 96 hours were considered for commercial diesel . processing data using spss software and statistical analysis probit analysis was performed with a confidence level of 95%. the common carp no deaths...

Green tea leaves contain antioxidant compounds that can be used as organic inhibitors in a corrosion process. Tea were extracted by maceration method using 70% ethanol solution with solid:solvent ratio of 1:8 (w/v) for 1 x 24 hours an atmospheric room. The extract was then concentrated rotary evaporator and separated solvent under vacuum conditions at 852 mbar, temperature 70oC rotation 80 rpm....

We report new interferometric observations of the CO (2 − 1) rotational transition on Titan. We find that the spectrum is best fit by a uniform profile of 52 ppm, with estimated errors of 6 ppm (40 to 200 km) and 12 ppm (200 to 300 km).
