Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Blood Biomarkers of Helicobacter pylori‐Infected Chronic Gastritis in Active Versus Stable Phases: A Clinical Indicator Analysis Combined With Proteomic and Metabolomic Investigations

iMetaMed, EarlyView.
Combining clinical data with serum proteomics and metabolomics, the HGB–CAPZB–acetic acid model was developed as a potential diagnostic index to distinguish the active and stable stages of Helicobacter pylori‐infected chronic gastritis, and the related mechanism was explored through multi‐omics.

Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

Journal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?
