Current Insight into Human Ornithine Aminotransferase: A Review

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 8, Page 1431-1441, August 2026.
ABSTRACT Human ornithine aminotransferase (hOAT) is a mitochondrial matrix pyridoxal‐5′‐phosphate enzyme (PLP) that catalyzes the reversible transfer of the δ‐amino group of L‐ornithine (L‐Orn) to α‐ketoglutarate (α‐KG) yielding glutamate‐5‐semialdehyde (GSA) and glutamate. GSA is prone to cyclize to Δ1‐pyrroline‐5‐carboxylate.

Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

British Journal of Pharmacology, Volume 183, Issue 15, Page 4091-4110, August 2026.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...

Diagnosis of Growth Hormone Deficiency in Children: Comparative Performance of Arginine Versus Glucagon as the First Stimulation Test

Clinical Endocrinology, Volume 105, Issue 2, Page 213-219, August 2026.
ABSTRACT Objective Growth hormone deficiency (GHD) diagnosis typically requires the performance of two sequential stimulation tests. Glucagon stimulation test (GST) and arginine stimulation test (AST) are widely used. This study aimed to determine the most suitable order of tests.

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 896-907, August 2026.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.

DNA‐mimic for Specific Surface Functionalization of Zr‐MOFs for Bacterial Targeting

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
We introduce phosphotyrosine‐modified PNA as a superior, single‐step post‐synthesis surface coating for PCN‐222. The DNA mimic allows for controlled post‐functionalization with single‐stranded DNA for the attachment of protein moieties for bacterial targeting. ABSTRACT Nanosized metal–organic frameworks (MOFs) are versatile platforms used in biomedical
