Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

Advanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Abnormal lipid droplets accumulation induced cognitive deficits in obstructive sleep apnea syndrome mice via JNK/SREBP/ACC pathway but not through PDP1/PDC pathway

Molecular Medicine, 2022
The mechanisms of chronic intermittent hypoxia (CIH)-induced cognitive deficits remain unclear. Here, our study found that about 3 months CIH treatment induced lipid droplets (LDs) accumulation in hippocampal nerve and glia cells of C57BL/6 mice, and ...

Neurological, Psychiatric, and Biochemical Aspects of Thiamine Deficiency in Children and Adults. [PDF]

, 2019
Thiamine (vitamin B1) is an essential nutrient that serves as a cofactor for a number of enzymes, mostly with mitochondrial localization. Some thiamine-dependent enzymes are involved in energy metabolism and biosynthesis of nucleic acids whereas others ...

Binding of pyruvate dehydrogenase to the core of the human pyruvate dehydrogenase complex [PDF]

FEBS Letters, 2008
In human (h) pyruvate dehydrogenase complex (PDC) the pyruvate dehydrogenase (E1) is bound to the E1‐binding domain of dihydrolipoamide acetyltransferase (E2). The C‐terminal surface of the E1β subunit was scanned for the negatively charged residues involved in binding with E2.

GSH‐Responsive Nanoparticles Enhance Hepatocellular Carcinoma Immunotherapy Through Synergistic Effects of Cuproptosis and PI3K Inhibitor Combination

Advanced Science, EarlyView.
ABSTRACT Cuproptosis, an emerging form of programmed cell death, is capable of inducing mitochondrial dysfunction. Moreover, the PI3K‐AKT‐mTOR signaling pathway contributes to tumor cell progression by reprogramming mitochondrial morphology and function.

Dynamic Imaging of LDH Inhibition in Tumors Reveals Rapid In Vivo Metabolic Rewiring and Vulnerability to Combination Therapy

Cell Reports, 2020
Summary: The reliance of many cancers on aerobic glycolysis has stimulated efforts to develop lactate dehydrogenase (LDH) inhibitors. However, despite significant efforts, LDH inhibitors (LDHi) with sufficient specificity and in vivo activity to ...

Gut Mycobiota‐Associated Tryptophan Catabolites Protect Against Metabolic Dysfunction‐Associated Steatotic Liver Disease

Advanced Science, EarlyView.
ABSTRACT Accumulating evidence suggests that the intestinal microbiota participates in the progression of metabolic dysfunction‐associated steatotic liver disease (MASLD) through microbiota‐host interaction. However, the beneficial role of commensal mycobiota in MASLD progression remains poorly understood.
