Phosphate acts directly on the calcium-sensing receptor to stimulate parathyroid hormone secretion

open access: yesNature Communications, 2019
Elevated inorganic phosphate levels promote excessive parathyroid hormone secretion, which contributes to the aetiology of secondary hyperparathyroidism.

The role of the PTHrP/Ihh feedback loop in the unusual growth plate location in mammalian metatarsals and pisiforms

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Longitudinal skeletal growth takes place in the cartilaginous growth plates. While growth plates are found at either end of conventional long bones, they occur at a variety of locations in the mammalian skeleton. For example, the metacarpals and metatarsals (MT) in the hands and feet form only a single growth plate at one end, and ...

A head start: The relationship of placental factors to craniofacial and brain development

open access: yesDevelopmental Dynamics, EarlyView.
Abstract In recent years, the importance of placental function for fetal neurodevelopment has become increasingly studied. This field, known as neuroplacentology, has greatly expanded possible etiologies of neurodevelopmental disorders by exploring the influence of placental function on brain development.

A practical self-made device in parathyroid autotransplantation for patients with secondary hyperparathyroidism

open access: yesJournal of International Medical Research, 2019
Objective Secondary hyperparathyroidism (sHPT) is one of the most serious complications in patients on long-term hemodialysis. These patients may suffer from metabolic bone diseases, severe atherosclerosis, and undesirable cardiovascular events ...

Vitamin D and calcium metabolism in horses in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Veterinary Science at Institute of Veterinary, Animal and Biomedical Sciences (IVABS), Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2016
The physiology of vitamin D in horses has not been studied in great depth. Few studies on vitamin D metabolites (25OHD2, 25OHD3, and 1,25(OH)2D) and their relationship to other serum analytes exist. In addition, some studies suggest that equine vitamin D

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

A case report: Giant cystic parathyroid adenoma presenting with parathyroid crisis after Vitamin D replacement [PDF]

open access: yes, 2012
Background: Parathyroid adenoma with cystic degeneration is a rare cause of primary hyperparathyroidism. The clinical and biochemical presentation may mimic parathyroid carcinoma.

Preoperative Vitamin D Supplementation to Reduce Hypocalcemia Following Total Thyroidectomy: Systematic Review and Meta‐Analysis of Randomized Clinical Trials

open access: yesHead &Neck, EarlyView.
ABSTRACT Objective This study aims to determine whether preoperative supplementation of vitamin D reduces the incidence of hypocalcemia following total thyroidectomy. Methods Conducted in conformity with the PRISMA statement, a systematic review and meta‐analysis of randomized clinical trials (RCT) was performed assessing postoperative hypocalcemia and

The potential role of environmentally associated DNA methylation in childhood acute lymphoblastic leukaemia subtypes

open access: yesInternational Journal of Cancer, EarlyView.
What's New? The rarity of acute lymphoblastic leukaemia and lack of available environmental data have made the role of environmental factors in genetic subtypes challenging to investigate. Here, the authors performed a CpG‐level analysis to investigate DNA methylation as an intermediate mechanism between environmental risk exposures and acute ...

Impaired Insulin sensitivity and Insulin secretion in Haemodialysis patients with and without Secondary Hyperparathyroidism [PDF]

open access: yes, 2004
The aim of our study was to investigate insulin sensitivity and beta cell function in hemodialysis (HD) patients without diabetes. We hypothesized that parathyroid gland function was a determinant of insulin sensitivity and/or beta cell function.
