Dose caffeinated energy drink is a consideration issue for endurance performance.

Caffeinated energy drinks are commonly taken to improve exercise performance, but there are few studies on the influence of different doses on an athlete's performance. We conducted a double-blind, randomized, counter-balanced, and crossover research study to examine the effects of low caffeinated energy drink (Low ED) or high caffeinated energy drink (High ED) supplement on the performance, haematological response, and oxidative stress in triathletes. Twelve male participants underwent three testing sessions separated by weekly intervals, consisting of sprint triathlon training (0.

An Unsymmetric Salamo-like Chemosensor for Fuorescent Recognition of Zn.

A new unsymmetric tetradentate salamo-like chemical sensor HL for fluorescent recognition of Zn has been designed and synthesized. The sensor can recognize Zn from other metal ions examined with selectivity, anti-interference, reliability and high sensitivity (LOD = 1.89 × 10 M) in ethanol/HO solution.
