Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

Interdisciplinary Medicine, EarlyView.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.

Hypoxanthine-guanine phosphoribosyltransferase and inosine 5’-monophosphate dehydrogenase activities in three mammalian species: aquatic (Mirounga angustirostris), semiaquatic (Lontra longicaudis annectens) and terrestrial (Sus scrofa)

Frontiers in Physiology, 2015
Aquatic and semiaquatic mammals have the capacity of breath hold (apnea) diving. Northern elephant seals (Mirounga angustirostris) have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min ...

Gut microbiome‐derived metabolites show promise in cancer research and therapy

Interdisciplinary Medicine, EarlyView.
The metabolites produced by the gut microbiome, which are subject to regulation by multiple factors, play a pivotal role in the progression of various types of cancer. These metabolites not only function as potential biomarkers for the early detection and monitoring of tumor development, but also actively participate in cancer therapeutic processes ...

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Salvage enzymes in nucleotide biosynthesis [PDF]

, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Multimodal Imaging Investigation of the Dentato‐Thalamo‐Cortical Pathway in Friedreich's Ataxia

Movement Disorders, EarlyView.
Abstract Background Friedreich's ataxia (FRDA) is a spinocerebellar neurodegenerative disorder. The dentato‐thalamo‐cortical (DTC) pathway, an important cerebellar output involved in motor control, plays a crucial role in the neural mechanisms underlying ataxia symptoms in FRDA.

Rehabilitation and return to activity after platelet‐rich plasma injections in chronic tendinopathies: Consensus from international experts

PM&R, EarlyView.
Abstract Background The effectiveness of platelet‐rich plasma (PRP) injections in chronic tendinopathies remains debated. Although the product's characteristics play a role, the impact of postinjection recommendations remains poorly investigated. Objective To establish principles and guidelines for post‐PRP injection rehabilitation and return to ...
