BMP1 inhibitor UK383367 improves MI-induced cardiac remodeling and fibrosis in mice via ameliorating macrophage polarization and mitochondrial dysfunction.

Despite optimized guideline-directed medical therapy, patients with myocardial infarction (MI) often develop heart failure (HF) primarily because of excessive fibrosis. Bone morphogenetic protein 1 (BMP1) plays a critical role in the fibrotic process, yet its specific role in post-MI myocardial fibrosis remains unclear. In this study, we investigated the complex dynamics between BMP1 and fibrotic processes, offering critical insights for novel strategies to mitigate pathological fibrosis in cardiovascular diseases.

Distribution characteristics and source analysis of heavy metals in surface sediments of the Yellow River estuary.

Ligand Control of Geometric Selectivity in Protosilylation of Acyclic α-Substituted α,β-Unsaturated -Sulfinyl Ketimines.

The copper(I)-catalyzed silyl conjugate addition to α-substituted α,β-unsaturated --butanesulfinyl ketimines presents a facile approach for the synthesis of acyclic β,β-disubstituted enesulfinamides. By varying the ligand associated with the copper catalysts, it is feasible to selectively produce multisubstituted enesulfinamides with either ()- or ()-configuration, thereby facilitating their effective use in the stereoselective nucleophilic reactions to construct less accessible acyclic quaternary or tetrasubstituted stereocenters, encompassing both absolute configurations.

Targeted Adherence and Enhanced Degradation of Feather Keratins by a Novel Prepeptidase C-Terminal Domain-Fused Keratinase.

Keratinases are valuable enzymes for converting feather keratin waste into bioactive products but often suffer from poor substrate specificity and low catalytic efficiency. This study reported the creating of a novel keratinase with targeted adherence and specific degradation on feather keratins by fusing prepeptidase C-Terminal (PPC) domain. A PPC domain of metalloprotease E423 specifically adsorbed feather keratins by hydrogen bonds and hydrophobic interactions in a time- and temperature-dependent manner.

To explore the expression and prognostic value of UHRF1 gene in soft tissue sarcoma (STS) and its related molecular mechanism. The expression data and clinicopathological parameters of STS were downloaded from the Cancer Genome Atlas (TCGA). The expression level of UHRF1 in STS and adjacent tissues and its relationship with clinicopathological characteristics were analyzed.

Deciphering the Genetic Links between Psychological Stress, Autophagy, and Dermatological Health: Insights from Bioinformatics, Single-Cell Analysis, and Machine Learning in Psoriasis and Anxiety Disorders.

The relationship between psychological stress, altered skin immunity, and autophagy-related genes (ATGs) is currently unclear. Psoriasis is a chronic skin inflammation of unclear etiology that is characterized by persistence and recurrence. Immune dysregulation and emotional disturbances are recognized as significant risk factors.

Detecting and characterizing new endofungal bacteria in new hosts: and in .

The fungus (=) is commonly saprotrophic, exhibiting a nature of decomposing organic matter. Additionally, it serves as a crucial starter in food fermentation and can act as a pathogen causing mucormycosis in humans and animals. In this study, two distinct endofungal bacteria (EFBs), associated with individual strains of , were identified using live/dead staining, fluorescence hybridization, transmission electron microscopy, and 16S rDNA sequencing.

Rational engineering S1' substrate binding pocket to enhance substrate specificity and catalytic activity of thermal-stable keratinase for efficient keratin degradation.

This study reports the rational engineering of the S1' substrate-binding pocket of a thermally-stable keratinase from Pseudomonas aeruginosa 4-3 (4-3Ker) to improve substrate specificity to typical keratinase (K/C > 0.5) and catalytic activity without compromising thermal stability for efficient keratin degradation. Of 10 chosen mutation hotspots in the S1' substrate-binding pocket, the top three mutations M128R, A138V, and V142I showing the best catalytic activity and substrate specificity were identified.

Effect of the physical rehabilitation program based on self-care ability in patients with acute ischemic stroke: a quasi-experimental study.

Introduction: It is the most practical goal of limb rehabilitation for stroke patients to make the upper limb, trunk, and lower limb joints link together as a whole and restore the ability to self-care. However, many previous studies focused on the single joint or single muscle group movement of stroke patients and did not integrate self-care ability training into the whole process of rehabilitation, which lacks accuracy, integrity, and systematization.

Methods: A quasi-experimental study was conducted in a tertiary hospital.

Association of C-reactive protein and complement factor H gene polymorphisms with risk of lupus nephritis in Chinese population.

Background: Complement overactivation is a major driver of lupus nephritis (LN). Impaired interactions of C-reactive protein (CRP) with complement factor H (CFH) have been shown as a pathogenic mechanism that contributes to the overactivation of complement in LN. However, genetic variations of neither CRP nor CFH show consistent influences on the risk of LN.
