TL;DR: It is concluded that the cloacal gland may be considered as an external indicator of testicular function of the birds and used as a simple and effective tool to predict the fertilizing ability of an individual male in view of the very small semen ejaculate that is very difficult to collect and evaluate for fertility.

TL;DR: Investigation of the ability of aflatoxin B1 to induce endogenous oxidative damages and the possible ameliorating effects of dietary melatonin (MEL) found long‐term rather than short‐term administration of MEL was more effective in rendering protection against AFB1‐induced toxicity.
Abstract: In the present study, the ability of aflatoxin B1 (AFB1) to induce endogenous oxidative damages and the possible ameliorating effects of dietary melatonin (MEL) were investigated. Newly hatched broiler chicks (n = 240) were fed aflatoxin-contaminated diets (0.5 or 1 mg kg−1 diet) with or without MEL (40 mg kg−1 bw) supplementation in diet for 40 days. AFB1 resulted in a significant increase in lipid peroxidation (LPO) in the liver and erythrocytes accompanied with suppression of superoxide dismutase (SOD) and catalase (CAT) enzyme activities of erythrocytes. It also caused a significant reduction in levels of serum proteins and marked elevation in activities of serum transaminases. AFB1 treatment also decreased both humoral and cell-mediated immune responses in growing chicks. Simultaneous administration of MEL with AFB1 resulted in an obvious improvement in all the tested parameters. Long-term rather than short-term administration of MEL was more effective in rendering protection against AFB1-induced toxicity. © 2009 Wiley Periodicals, Inc. Environ Toxicol 26: 153–160, 2011.

TL;DR: The present article gives an overview of the currently available assays of nitrite and nitrate in biological fluids based on the Griess reaction, the most frequently used analytical approach to quantitate the major metabolites of NO, i.e. nitriteand nitrate, in a variety of biological fluids, notably blood and urine.

TL;DR: A review of using Griess Reaction method to determine nitric oxide production in biological systems finds it to be a waste of time and money to use this method.
