The Mechanism of Modulation of Cardiac Force by Temperature.
Int J Mol Sci
January 2025
PhysioLab, University of Florence, 50019 Sesto Fiorentino, Italy.
In maximally Ca-activated demembranated fibres from the mammalian skeletal muscle, the depression of the force by lowering the temperature below the physiological level (~35 °C) is explained by the reduction of force in the myosin motor. Instead, cooling is reported to not affect the force per motor in Ca-activated cardiac trabeculae from the rat ventricle. Here, the mechanism of the cardiac performance depression by cooling is reinvestigated with fast sarcomere-level mechanics.

Electronic address:
Background: Ambient temperatures and PM can trigger myocardial infarction (MI), while little is known about the complex interplay between these two factors on MI, especially morbidity.
Objectives: To investigate bidirectional effect modifications of temperature and PM on MI morbidity and mortality.
Methods: A time-stratified case-crossover study was conducted utilizing high-resolution data of temperature and PM, along with 498,077 MI cases from the citywide registry in Beijing, China from 2007 to 2021.
Eutectogel-Based Drug Delivery: An Innovative Approach for Atenolol Administration.

Hypertension affects 32% of adults worldwide, leading to a significant global consumption of cardiovascular medications. Atenolol, a β-adrenergic receptor blocker, is widely prescribed for cardiovascular diseases such as hypertension, angina pectoris, and myocardial infarction. According to the Biopharmaceutics Classification System (BCS), atenolol belongs to Class III, characterized by high solubility but low permeability.

Objectives: Due to poor treatment adherence and lifestyle-based interventions, chronic hypertension is a dominant risk factor predisposing individuals to heart failure and malignant arrhythmias. We investigated the impact of the postnatal acclimation of hairless SHR to ambient temperature that is, for them, below thermoneutrality, on the electrical coupling protein connexin-43 (Cx43) and pro-fibrotic markers in both heart ventricles of male and female hairless SHR rats compared to the wild SHR.
Methods: Some 6-month-acclimated male and female hairless SHR as well as age- and sex-matched wild SHR were included and compared with the non-hypertensive Wistar strain.
Biomimetic niosomal versus liposomal nanoparticle-based aspirin injection for treating stroke and myocardial infarction.

In this work, we are comparing biomimetic niosomal nanoparticles (BNNs) with biomimetic liposomal nanoparticles (BLNs) and studying their drug carrier properties. A-BNNs and A-BLNs are prepared by lipid hydration method and characterized using DLS for size and zeta potential analysis, surface morphology by SEM, structural details by TEM, crystallinity and phase change by XRD, thermodynamic properties by DSC, TGA and DTGA, drug carrier properties by entrapment efficiency, drug release studies by open-end tube method and its mechanistic assessment by fitting with various models such as zero order, first order, Higuchi and Korsmeyer-Peppas models. The A-BNNs had an average size of 157.
