Paroxetine, a selective serotonin reuptake inhibitor, is widely used in the clinical treatment of depression. While several antidepressants show promise as geroprotectors, the role of paroxetine in aging remains unclear. In this study, we evaluated the lifespan extension effect of paroxetine in Caenorhabditis elegans (C.

ESC Heart Fail
December 2024
Department of Rehabilitation Medicine, China-Japan Friendship Hospital, Beijing, China.
Aims: Biomarkers are pivotal in the management of heart failure (HF); however, their lack of cardiac specificity could limit clinical utility. This study aimed to investigate the transcoronary changes and intracardiac production of these biomarkers.
Methods: Transcoronary gradients for B-type natriuretic peptide (BNP) and five novel biomarkers-galectin-3 (Gal-3), soluble suppression of tumourigenicity 2 (sST2), tissue inhibitor of metalloproteinase 1 (TIMP-1), growth differentiation factor 15 (GDF-15) and myeloperoxidase (MPO)-were determined using femoral artery (FA) and coronary sinus (CS) samples from 30 HF patients and 10 non-HF controls.
The Role of Snake Venom Proteins in Inducing Inflammation Post-Envenomation: An Overview on Mechanistic Insights and Treatment Strategies.
Toxins (Basel)
December 2024
School of Biotechnology, Amrita Vishwa Vidyapeetham, Kollam 690 525, Kerala, India.
The intricate combination of organic and inorganic compounds found in snake venom includes proteins, peptides, lipids, carbohydrates, nucleotides, and metal ions. These components work together to immobilise and consume prey through processes such as paralysis and hypotension. Proteins, both enzymatic and non-enzymatic, form the primary components of the venom.

Membranes (Basel)
November 2024
Department of Biochemistry, University of Illinois Urbana, Champaign, IL 61801, USA.
Protein-lipid interactions demonstrate important regulatory roles in the function of membrane proteins. Nevertheless, due to the semi-liquid nature and heterogeneity of biological membranes, and dissecting the details of such interactions at high resolutions continues to pose a major challenge to experimental biophysical techniques. Computational techniques such as molecular dynamics (MD) offer an alternative approach with both temporally and spatially high resolutions.
