Physiological regulation of calcium and phosphorus utilization in laying hens

Frontiers in Physiology, 2023
Commercial laying hens can produce one egg approximately every 24 h. During this process, regulatory systems that control vitamin D3 metabolism, calcium and phosphorus homeostasis, and intestinal uptake of these minerals work in concert to deliver ...

Painful and Prolonged Muscle Cramps following Insulin Injections in a Patient with Type 2 Diabetes Mellitus: Revisiting the 1992 Duke Case

Frontiers in Endocrinology, 2017
A 56-year-old middle-eastern male with a long-standing history of poorly controlled type 2 diabetes mellitus presented to us complaining of severely painful bilateral upper and lower extremity cramps occurring shortly after his rapid-acting insulin ...

Knowledge, attitudes, and practices on osteoporosis prevention and treatment strategies in the MENA region: a systematic review protocol

BMJ Open
Background Osteoporosis represents a growing public health concern in the Middle East and North Africa (MENA) region, where ageing populations and limited healthcare access contribute to high fracture rates and poor treatment adherence.

Organic phosphate but not inorganic phosphate regulates Fgf23 expression through MAPK and TGF-ꞵ signaling

iScience
Summary: One of the main regulators of phosphate homeostasis is fibroblast growth factor 23 (FGF23), secreted by osteocytes. The effects of organic versus inorganic dietary phosphate on this homeostasis are unclear.

ON THE RELATION OF TETANY TO THE PARATHYROID GLANDS AND TO CALCIUM METABOLISM

Journal of Experimental Medicine, 1909
1. Tetany occurs spontaneously in many forms and may also be produced by the destruction of the parathyroid glands. Recent researches tend to demonstrate an intimate relation between the various forms of tetany and relative or absolute insufficiency of ...

Mitochondrial calcium exchange in physiology and disease.

Physiological Reviews, 2021
The uptake of calcium into and extrusion of calcium from the mitochondrial matrix is a fundamental biological process that has critical effects on cellular metabolism, signaling, and survival.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Regulation of Calcium Metabolism

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1976
This paper reviews the regulation of calcium metabolism in man. The body's calcium economy is determined by the relationship between the intestinal absorption of calcium, the renal handling of calcium, and by the movements of calcium in and out of the skeleton. These processes are influenced by many factors, the most important of which are parathyroid

An Update on Vitamin D Metabolism

International Journal of Molecular Sciences, 2020
Vitamin D is a steroid hormone classically involved in the calcium metabolism and bone homeostasis. Recently, new and interesting aspects of vitamin D metabolism has been elucidated, namely the special role of the skin, the metabolic control of liver ...
