Protein and Peptide Inhibitors of Mineralization: A Systematic Review of In Vitro Studies

Journal of Peptide Science, Volume 32, Issue 7, July 2026.
In vitro evidence from crystallization assays demonstrates that peptides inhibit mineral nucleation and crystal growth through sequence‐dependent interactions (acidic residues and phosphorylation) with mineral surfaces. In cell cultures, these molecules reduce calcium deposition and ALP activity and modulate the expression of biomineralization‐related ...

Refractory hypercalcemia due to an ectopic mediastinal parathyroid gland in a hemodialysis patient: a case report

BMC Nephrology, 2019
Background Hypercalcemia crisis is a complex disorder rarely induced by tertiary hyperparathyroidism, which clinically presents as nonsuppressible parathyroid hyperplasia with persistent increased PTH levels and hypercalcemia. It is one of the major risk

Scientific Report on consumer health‐based guidance values for trifluoroacetic acid

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The European Commission asked EFSA to provide a scientific report according to Article 31 of Regulation (EC) No 178/2002, in conjunction with Regulation (EC) No 1107/2009, to revise consumer health‐based guidance values, i.e. acceptable daily intake (ADI) and acute reference dose (ARfD), for trifluoroacetic acid (TFA). EFSA launched a targeted

The role of anatomical and functional orientation in identification of parathyroid glands for patients with parathyroidectomy

Frontiers in Endocrinology
ObjectiveTo investigate diagnostic approaches for preoperative localization of secondary hyperparathyroidism, as well as to give surgeons with precise parathyroid gland localization and imaging so that surgery can be performed safely.MethodsThe clinical ...

An occult ectopic parathyroid adenoma in a pediatric patient: a case report and management algorithm

, 2017
Background:Hyperparathyroidism (HPT) is a rare disease in the pediatric population, and optimal management may be unclear if it is due to an occult parathyroid adenoma.

An Approach to a Patient With Primary Hyperparathyroidism and a Suspected Ectopic Parathyroid Adenoma.

, 2022
Primary hyperparathyroidism (PHPT) is characterized by hypercalcemia driven by excess parathyroid hormone (PTH) secretion. PHPT is a common endocrine condition with a prevalence of 1 to 7 cases per 1000 adults.

Video-assisted mediastinoscopy (VAM) for surgical resection of ectopic parathyroid adenoma

Journal of Cardiothoracic Surgery, 2007
Background Ectopic mediastinal parathyroid adenomas or hyperplasia account for up to 25% of primary hyperparathyroidism (HPT). Two percent of them are not accessible by standard cervical surgical approaches.

Persistent primary hyperparathyroidism: an uncommon location for an ectopic gland: Case report and review [PDF]

, 2012
Primary hyperparathyroidism (PHPT) is a common endocrine disorder that mainly affects middle-aged women. Patients are usually asymptomatic. The disease might be ascribable to hyperplasia, carcinoma, and single or multiple adenomas.

An Asymptomatic Primary Hyperparathyroidism Case Due to a Mediastinum Localized Ectopic Giant Parathyroid Adenoma

Endocrinology Research and Practice, 2019
The majority of primary hyperparathyroidism is caused by a parathyroid adenoma adjacent to the thyroid gland. Parathyroid adenomas rarely originate from an ectopic parathyroid gland and develop as a result of embryological migration defect.
