Protein inhibitor of NOS1 plays a central role in the regulation of NOS1 activity in human dilated hearts [PDF]
, 2016 An essential factor for the production of nitric oxide by nitric oxide synthase 1 (NOS1), major modulator of cardiac function, is the cofactor tetrahydrobiopterin (BH4).

iMetaOmics, EarlyView.Our study employed an integrated lipidomics and metabolomics approach to elucidate Helicobacter pylori‐driven metabolic perturbations along the gut–brain axis. H. pylori infection was established in gastric epithelial (AGS) cells, and the resulting conditioned media (secretome) was collected and exposed to neuronal (IMR‐32) cells.

Skin Hyperpigmentation: An Under‐Recognized Dermatological Clue to Vitamin B12 Deficiency
Clinical Case Reports, Volume 14, Issue 5, May 2026.Hyperpigmentation over the dorsal aspect of both hands, prominently involving the knuckles. ABSTRACT Cutaneous hyperpigmentation, an overlooked manifestation, can be an early sign of vitamin B12 deficiency. This case highlights symmetric pigmentation on the dorsum of hands and palms in a long‐term vegetarian.

A Novel Multimodal LC–MS/MS Panel for the Comprehensive Diagnosis of Neurometabolic Disorders in CSF
Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.ABSTRACT Metabolic testing of cerebrospinal fluid (CSF) is essential for early diagnosis of neurometabolic disorders. However, the large number of differential diagnoses, the phenotypic variance within a clinical picture, and the disease rarity complicate targeted metabolic diagnostics.

Hippo Pathway Drives Durable Non‐Cell‐Autonomous Ferroptosis Resistance in Lung Cancer
Cancer Science, Volume 117, Issue 3, Page 683-694, March 2026.YAP/TAZ, key effectors in lung cancer progression, paradoxically sensitize tumor cells to ferroptosis. This study reveals that YAP/TAZ‐low cells confer non‐cell‐autonomous, GCH1‐mediated durable ferroptosis resistance to neighboring YAP/TAZ‐high cells via a soluble factor, highlighting a Hippo pathway‐linked mechanism of tumor adaptation and survival ...
