Article Abstract

Throughout the course of evolution, organisms and cells have evolved a suite of mechanisms to manage persistent stimuli, thereby preserving cellular and organismal homeostasis. Upon detecting stress signals, cells activate a transcriptional response termed the mitochondrial unfolded protein response (UPR). This response is crucial for maintaining protein homeostasis, facilitating mitochondrial function recovery, promoting cell survival, and ultimately influencing lifespan. Striated muscles play a pivotal role in oxygen supply, movement, and metabolism. The aging of these muscles can lead to heart failure, arrhythmias, and sarcopenia, significantly impacting quality of life and lifespan. Given the intimate connection between UPR and striated muscle aging, UPR emerges as a potential therapeutic target for mitigating the effects of striated muscle aging. In this review, we delve into the role of UPR in striated muscle aging, drawing upon the extant molecular regulatory mechanisms of UPR. This exploration may enhance our understanding of the underlying mechanisms of striated muscle aging and aid in the identification of potential drug targets.

Maintenance of organismal function requires tightly regulated biomolecular communication. However, with aging, communication deteriorates, thereby disrupting effective information flow. Using information theory applied to skeletal muscle single cell RNA-seq data from young, middle-aged, and aged animals, we quantified the loss of communication efficiency over time.

Objectives: To explore the relationships between cardiac parameters and body composition indices, identifying predictors of subclinical cardiac systolic dysfunction.

Methods: Using anthropometric and serological parameters, echocardiography, and body composition analysis, this study evaluated metabolic profiles, cardiac remodeling patterns, and body composition characteristics in young adult obese patients, while quantifying the correlations between cardiac parameters and body composition indices. Subclinical left ventricular systolic dysfunction was defined as global longitudinal strain (GLS) < 18%.

Purpose: To objectively quantify, in East Asians and Caucasians, the width and distribution of the retro-orbicularis oculi and frontalis fat (ROOF) pad, subcutaneous fat, and orbicularis oculi muscle (OOM) at the superior orbital rim margin as well as 5 mm superior and inferior to this point.

Methods: Thirty adults were studied by high-resolution, surface coil MRI. In the quasi-sagittal image through the globe center, the ROOF, subcutaneous fat, and OOM thickness were measured anterior to the orbital septum, at 3 points: at the superior orbital rim, and 5 mm superior, and 5 mm inferior to the rim.

Background: Liver cirrhosis, characterized by chronic inflammation, is frequently complicated by malnutrition. Nutritional indices, such as the prognostic nutritional index (PNI) and the skeletal muscle index (SMI), calculated as the muscle area quantified via CT scans at the third lumbar vertebra level divided by the square of the patient's height in meters (cm/m), are associated with outcomes in inflammatory diseases.

Objectives: We aimed to evaluate the diagnostic efficacy of the PNI both independently and in combination with the SMI for identifying malnutrition in cirrhosis and to explore their prognostic implications.

Neutral Lipid Storage Disease with Myopathy (NLSDM) is a rare lipid metabolism disorder caused by impaired Adipose Triglyceride Lipase (ATGL) activity, leading to neutral lipid accumulation in various tissues. It typically manifests with progressive skeletal myopathy, with an onset of around 35 years. In addition, some patients develop cardiomyopathy and liver dysfunction.
