Background: The proposed role of Vitamin D Receptor (VDR) in various cancers underscores the importance of vitamin D compounds as a novel therapeutic agent in the prevention of occurrence and progression of cancer. Vitamin D Receptor (VDR) expression in gallbladder cancer (GBC) has not been widely analyzed yet. In the present study, an attempt has been made to study VDR expression and the role of vitamin D supplementation during palliative chemotherapy in advanced GBC.
Methods: Expression of VDR was analyzed in benign cholecystectomy specimens (n=11), and GBC specimens (n=32). Thirty patients with advanced GBC were subjected to palliative chemotherapy. Out of them, 19 patients were supplemented with Vitamin D and 11 patients were not. Effect of vitamin D supplementation on the change in vitamin D scores and improvement in quality of life (QOL) were assessed by EORTC QLQ c30 version 3.0. and the difference in outcome between the two groups were studied.
Results: Mean intensity, staining and immunoreactivity scores signifying VDR expression were decreased in the studied population of GBC when compared to benign disease. In palliative setting, vitamin D supplementation significantly improved the quality of life. However, the effect on disease- specific survival, although present, was not statistically significant.
Conclusion: VDR expression downregulation is associated with increasing malignant process. Vitamin D may act as sensitizers for tumor cell death besides downplaying potential harmful effects of palliative chemotherapy thus reducing the associated morbidity. This study assumes importance as the first clinical study reporting VDR expression in GBC tissue and the possible role of vitamin D supplementation in patients with advanced disease.

Introduction: Zellweger spectrum disorder (ZSD) refers to a group of autosomal recessive genetic disorders that affect multiple organ systems and are predominantly caused by pathogenic variants in PEX genes. ZSD present a wide clinical spectrum, ranging from the most severe form, Zellweger syndrome, to the mildest form, Heimler syndrome.

Forty-eight multiparous Holstein cows were used in a randomized complete block design and assigned to one of 4 treatments in a 2x2 factorial arrangement of treatments to determine the effects of supplemental palmitic acid (C16:0) and chromium (Cr) on production responses of early-lactation cows. During the fresh period (FR; 1-24 d in milk), cows were fed one of 4 treatments: (1) a diet containing no supplemental C16:0 or Cr (CON); (2) diet supplemented with an 85% C16:0-enriched supplement (PA); (3) diet supplemented with Cr-propionate (CR); and (4) diet supplemented with a C16:0-enriched supplement and Cr-propionate (PACR). The C16:0-enriched supplement was added at 1.
