TLDR
Overall observations suggest that excessive dietary calcium enhances the generation of free-radicals resulting in structural and functional disruption of male reproduction.Abstract:
Calcium is essential for functioning of different systems including male reproduction. However, it has also been reported as chemo-castrative agent. The study has been undertaken to elucidate the effect of excessive dietary calcium on male reproductive system in animals with possible action. Adult male healthy rats fed CaCl2 at different doses (0.5, 1.0 and 1.5 g%) in diet for 13 and 26 days to investigate reproductive parameters as well as the markers of oxidative stress. Significant alteration was found (P < 0.05) in testicular and accessory sex organs weight, epididymal sperm count, testicular steroidogenic enzyme (Δ5 3β-HSD and 17β-HSD) activities, serum testosterone, LH, FSH, LPO, activities of antioxidant enzymes, testicular histoarchitecture along with adrenal Δ5 3β-HSD activity with corticosterone level in dose- and time-dependent manner. Overall observations suggest that excessive dietary calcium enhances the generation of free-radicals resulting in structural and functional disruption of male reproduction.read more

The Laboratory Rat: Relating Its Age With Human's
TL;DR: The overall findings indicate that rats grow rapidly during their childhood and become sexually mature at about the sixth week, but attain social maturity 5-6 months later, which must be taken into consideration while analyzing the results or selecting the dose of any research in rats when age is a crucial factor.

Health Impacts of Yoga and Pranayama: A State-of-the-Art Review
TL;DR: Yoga is reported to reduce stress and anxiety, improves autonomic functions by triggering neurohormonal mechanisms by the suppression of sympathetic activity, and even, now-a-days, several reports suggested yoga is beneficial for physical health of cancer patients.

Environmental and occupational exposure of metals and their role in male reproductive functions.
TL;DR: This review summarizes the effects of more than 20 metals that, research has indicated, may influence male reproductive health and suggests a need for further research in those chemicals that are reactive and capable of covalent interactions in biological systems.
A Scientific Review of Age Determination for a Laboratory Rat: How Old is it in Comparison with Human Age?
TL;DR: It is shown that rat-human age correlations differ markedly at different stages of life and development, from the weaning to aged phase of life, and metaphorically illustrates the correlation of their different age periods.

Involvement of the Superoxide Anion Radical in the Autoxidation of Pyrogallol and a Convenient Assay for Superoxide Dismutase
TL;DR: The autoxidation of pyrogallol was investigated in the presence of EDTA in the pH range 7.9–10.6, indicating an almost total dependence on the participation of the superoxide anion radical, O2·−, in the reaction.
