Divergent Atrial Transcriptomic Signatures in Diabetic and Nondiabetic Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Diabetes alters the atrial transcriptome in atrial fibrillation, characterized by enhanced mitochondrial ATP synthesis, suppressed immune and inflammatory pathways, and distinct miRNA expression profiles, suggesting metabolic and epigenetic remodeling of the atrial substrate.

SIRT Family: Biological Functions and Therapeutic Targets

MedComm, Volume 7, Issue 8, August 2026.
SIRT1–SIRT7 networks from transgenic mice to human‑relevant therapeutic targets. SIRT1–SIRT7 form an isoform‑, organ‑, and disease‑specific regulatory network. Transgenic Sirt1–7 mouse models define central regulatory SIRTs (SIRT1, SIRT3, SIRT6), context‑dependent modifiers (SIRT2, SIRT4, SIRT5, SIRT7), and their key mechanisms and target organs. These

Characterizing Metabolic and Compositional Heterogeneity of Calf Muscle Using CEST MRI at 3 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
This study used 3 T CEST MRI to characterize metabolic and compositional heterogeneity in eight healthy calf muscles, focusing on amide, PCr, rNOE, and MT contrasts. Distinct signatures emerged between deep stabilizer and superficial powerhouse muscles. Significant correlations with age, fat content, BMI, and strength (e.g., rNOE vs. strength) revealed

Mitoquinone Prevents Cardiac Dysfunction by Normalizing Mitochondrial ROS and Calcium Handling in Acute Myocardial Infarction

Acta Physiologica, Volume 242, Issue 8, August 2026.
ABSTRACT Acute myocardial infarction (MI) is the leading cause of heart failure (HF). However, the role of mitochondrial ROS (ROSm) in early MI dysfunction remains unclear. This study aimed to evaluate the impact of MitoQ on cardiac function in cases of heart HF following MI.

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, Volume 183, Issue 15, Page 4321-4343, August 2026.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.

Unveiling Gut Homeostasis Disruption in Sepsis: Towards an Integrated Mechanistic and Translational Roadmap

Cell Proliferation, Volume 59, Issue 8, August 2026.
Elucidating the contribution of gut‐organ axes will provide new insights for developing combined therapeutic strategies against sepsis‐associated multiple organ dysfunction. ABSTRACT Sepsis, a life‐threatening clinical syndrome precipitated by a maladaptive host response to infection, is associated with substantial morbidity and high mortality rates ...

Phosphate and acidosis cause fibre type‐specific changes to cellular and molecular contractile mechanics at 37°C in skeletal muscle from older adults

Experimental Physiology, Volume 111, Issue 8, Page 3753-3771, 1 August 2026.
Abstract Intracellular accumulation of hydrogen ions (H+) and inorganic phosphate (Pi) has temperature‐dependent effects on single‐fibre contractile function between 10°C and 30°C. In vivo, human skeletal muscle temperatures range between 35‐39°C, and although contractile function is highly dependent on temperature, the effects of fatigue‐inducing [H+]
