Cerebral Infarction: Epidemiology, Classification, Mechanisms, Diagnosis, and Management

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Within minutes after ischemia onset, deprivation of oxygen and glucose leads to rapid ATP depletion, resulting in failure of Na+/K+‐ATPase activity and membrane depolarization. This ionic imbalance promotes uncontrolled synaptic release of glutamate and excessive activation of postsynaptic NMDA and AMPA receptors.

Nanoceria Nanozyme Attenuates CoCl2‐Induced Oxidative Stress and Mitochondrial Dysfunction in H9c2 Cardiomyoblasts

open access: yesNano Select, Volume 7, Issue 4, April 2026.
This study shows that nanoceria protect H9c2 cardiomyoblasts from CoCl2‐induced chemical stress. Nanoceria reduces reactive oxygen species, preserves mitochondrial function, and regulates genes involved in antioxidant defense, intrinsic apoptosis, and inflammation. These findings highlight nanoceria's potential as a redox‐active nanozyme for protecting

Toxic mechanisms of amyloid oligomers and therapeutic strategies

open access: yesProtein Science, Volume 35, Issue 4, April 2026.
Abstract Amyloid oligomers are increasingly recognized as the major toxic contributors across protein‐misfolding disorders. In this review, we cover mechanistic evidence showing how these transient and structurally heterogeneous oligomers disrupt cellular homeostasis by: (i) permeabilizing lipid membranes and forming ion‐conducting pores; (ii ...

Comparative Genomics Provide Insights Into Karyotype Evolution in Vespertilionid Bats (Vespertilionidae, Chiroptera)

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Studies elucidating the molecular basis and evolutionary consequences of karyotypic changes in mammals remain scarce. Here, we investigate chromosomal evolution by focusing on two contrasting lineages within the family Vespertilionidae (Chiroptera): the karyotypically variable tribe Pipistrellini and the highly conserved genus Myotis ...

Role of Succinate Dehydrogenase in Age‐Related Th17 Inflammation

open access: yesAging Cell, Volume 25, Issue 4, April 2026.
Age‐induced mitoSTAT3‐dependent upregulation of mitochondrial complex II; succinate dehydrogenase (SDH), in CD4+ T cells promotes an imbalance in the levels of metabolites succinate and fumarate, characterized by lower succinate and higher fumarate. Changes in the metabolites alter mitochondrial structure and function and promote HIF1α to induce the ...

Autophagy‐Independent Function of ATG‐18 Is Essential for Gonadal Longevity in Caenorhabditis elegans

open access: yesAging Cell, Volume 25, Issue 4, April 2026.
Neuronal and intestinal ATG‐18 promote longevity conferred by germline removal in C. elegans via non‐autophagic functions. In the intestine, ATG‐18 regulates lifespan through its interaction with the gluconeogenic enzyme PCK‐2. ABSTRACT Autophagy, a highly conserved cellular degradation process, plays essential roles in various physiological processes ...

The Preservation of Muscle Mitochondrial Machinery During Hypometabolic Hibernation in Scandinavian Brown Bears (Ursus arctos)

open access: yesActa Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Unlike humans, brown bears (Ursus arctos) uniquely preserve skeletal muscle mass and function during months of hibernation despite prolonged fasting and inactivity. We investigated how mitochondrial energetics respond in skeletal muscle to support this remarkable resilience.
