Abstract:
... Triclosan (TCS) is a ubiquitous antimicrobial used in daily consumer products. Previous reports have shown that TCS could induce hepatotoxicity, endocrine disruption, disturbance on immune function and impaired thyroid function. Kidney is critical in the elimination of toxins, while the effects of TCS on kidney have not yet been well-characterized. The aim of the present study was to investigate t ...

Abstract:
... Traditional Chinese fermented foods are favored by consumers due to their unique flavor, texture and nutritional values. A large number of microorganisms participate in the process of fermentation, especially lactic acid bacteria (LAB), which are present in almost all fermented foods and contribute to flavor development. The formation process of flavor is complex and involves the biochemical conve ...

Abstract:
... Background: Tortoises, with their slow and unhurried reputation, might seem unlikely candidates for critical care and emergency treatment. Although they may present some challenges in recognising whether intensive or ‘critical’ care is indicated, by addressing first principles from other species and considering tortoises' ectothermic metabolism, simple supportive and monitoring techniques can mark ...

Suppressed resting metabolic rate (RMR) has been observed during periods of low EA. Thus, it has been suggested that the ratio of RMR measured via indirect calorimetry to predictive RMR using a standard predictive equation (RMR ratio) may be a useful assessment of EA in athletes.
