Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

Advanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore

IGFBP5 Restores Endometrial Receptivity and Rescues Implantation Failure in Polycystic Ovary Syndrome

Advanced Science, EarlyView.
Impaired endometrial receptivity contributes to the poor pregnancy outcomes in women with PCOS. The authors found that decreased endometrial IL‐22 levels and disrupted STAT3‐IGFBP5 signaling pathway contributed to impaired endometrial receptivity. Supplementation with IL‐22 or IGFBP5 exerts a protective effect on implantation failure in PCOS‐like mice,

Clinical applications of genetic analysis and liquid chromatography tandem-mass spectrometry in rare types of congenital adrenal hyperplasia

BMC Endocrine Disorders, 2021
Background Our study aims to summarize the clinical characteristics of rare types of congenital adrenal hyperplasia (CAH) other than 21-hydroxylase deficiency (21-OHD), and to explore the clinical applications of genetic analysis and liquid ...

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

Advanced Science, EarlyView.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...

A Neonate Presenting with Severe Dehydration - A Case of Congenital Adrenal Hyperplasia with Salt Losing Crisis

Journal of Nepal Medical Association
Congenital adrenal hyperplasia (CAH) is a rare autosomal recessive disorder caused by mutations in genes involved in cortisol biosynthesis in the adrenal gland. Depending on the enzymatic defect, the symptoms, signs, and laboratory findings differ.

Sentience in cephalopod molluscs: an updated assessment

Biological Reviews, EarlyView.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Congenital Adrenal Hyperplasia Presenting as Life Threatening Hyponatremic Dehydration: A Tale of Missed Diagnosis [PDF]

Journal of Clinical and Diagnostic Research
Congenital Adrenal Hyperplasia (CAH) is a group of autosomal recessive disorders that occur due to defects in steroid synthesis. It is characterised by a deficiency of adrenocortical hormones and an excess of steroid precursors.

Profiles of 21-Carbon Steroids in 21-hydroxylase Deficiency [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2015
Context: Marked elevations of 17-hydroxyprogesterone (17OHP) are characteristic of classic 21-hydroxylase deficiency (21OHD). Testing of 17OHP provides the basis for 21OHD diagnosis, although it suffers from several pitfalls.
