Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.This study investigates the neuroprotective effect of vitamin D against cisplatin‐induced mitochondrial damage and oxidative stress (ROS). HO‐1 expression is increased by vitamin D, which triggers Nrf2 activation and nuclear translocation. The results demonstrate that vitamin D protects brain tissue by strengthening the antioxidant defense system ...

Calcitriol corrects bone loss induced by oophorectomy in rats
, 1986 The effects of calcitriol on histomorphometric parameters of bone structure, formation, and resorption were evaluated in 21 normal or oophorectomized rats. Twelve rats were oophorectomized; six of these received daily subcutaneous injections of 135 pmol

Redox Regulation and Oxidative Stress in Health and Disease: Mechanisms and Therapeutic Targeting
MedComm – Future Medicine, Volume 5, Issue 2, June 2026.Reactive species serve crucial roles which are tightly regulated in both physiological as well as disease states. At physiological levels, these species are integral to redox signaling, while uncontrolled redox promotes disease pathology. This review examines the dysregulation of these processes.

Circadian Clock Regulates Epidermal Endocrine System in Homeostatic Skin Pigmentation
Experimental Dermatology, Volume 35, Issue 6, June 2026.ABSTRACT The circadian clock regulates multiple physiological processes in the skin, including local hormone synthesis and pigmentation. However, how circadian regulation interacts with epidermal endocrine signalling in melanocytes remains unclear.

Production and degradation of calcitriol in renal failure rats
, 1987 We studied the metabolism of calcitriol in renal failure achieved by nephrectomy in three groups of rats. Group 1 (n = 7) had sham operation of nephrectomy. Group 2 (n = 8) had unilateral nephrectomy. Group 3 (n = 7) had 5/6 nephrectomy.
