A periplasmic protein modulates the proteolysis of peptidoglycan hydrolases to maintain cell wall homeostasis in .

Bacterial cell wall assembly and remodeling require activities of peptidoglycan (PG) hydrolases as well as PG synthases. In particular, the activity of DD-endopeptidases, which cleave the 4-3 peptide crosslinks in PG, is essential for PG expansion in gram-negative bacteria. Maintaining optimal levels of DD-endopeptidases is critical for expanding PG without compromising its integrity.

N-Cadherin promotes cardiac regeneration by potentiating pro-mitotic β-Catenin signaling in cardiomyocytes.

Adult human hearts exhibit limited regenerative capacity. Post-injury cardiomyocyte (CM) loss can lead to myocardial dysfunction and failure. Although neonatal mammalian hearts can regenerate, the underlying molecular mechanisms remain elusive.

Strong Hydrophobic Interaction of High Molecular Weight Chitosan in Aqueous Solution.

Chitosan is a versatile bioactive polysaccharide in various industries, such as pharmaceuticals and environmental applications, owing to its abundance, biodegradability, biocompatibility, and antibacterial properties. To effectively harness its potential for various purposes, it is crucial to understand the mechanisms of its interaction in water. This study investigates the interactions between high molecular weight (HMW, >150 kDa) chitosan and four different functionalized self-assembled monolayers (SAMs) at three different pHs (3.

Efficacy of latissimus dorsi and teres major tendon transfer in anterosuperior irreparable rotator cuff tears and posterosuperior irreparable rotator cuff tears.

Background: There are various options of tendon transfer according to the different types of irreparable rotator cuff tears (IRCTs). However, there were no clear treatment options for the IRCTs involving the anterior, superior and posterior rotator cuff tears (global IRCTs). Latissimus dorsi and teres major (LDTM) could be transferred anteriorly or posteriorly in global IRCTs.

Examining the Relationship of Cannabis use Patterns, Mental Health, and Sociodemographic Factors: A Focus on Cannabis Vaping, Smoking and Dual-Use.

Background: Cannabis vaping, and co-use with cannabis smoking, can exacerbate the risks of developing respiratory diseases and cannabis dependence. This study aims to examine the mental health profiles and sociodemographic correlates of adults who vape cannabis and engage in dual cannabis use (vaping/ smoking), compared to those who smoke cannabis.

Methods: The most recent, cross-sectional wave of the Population Assessment of Tobacco and Health Study (Wave 6) was used in this study.
