Background: Direct-to-implant (DTI) breast reconstruction offers immediate aesthetic and psychological benefits, but the role of acellular dermal matrix (ADM) remains debated. Using a multi-institutional database, this study evaluates and compares outcomes between ADM-assisted and non-ADM DTI procedures.
Methods: The American College of Surgeons National Surgical Quality Improvement Program database from 2008 to 2022 was queried to identify female patients who underwent DTI breast reconstruction for oncological purposes.
Structure-Based Virtual Screening Identifies 2-Arylthiazole-4-Carboxylic Acids as a Novel Class of Nanomolar Affinity Ligands for the CaMKIIα Hub Domain.

The Ca/calmodulin-dependent protein kinase II α (CaMKIIα) plays a crucial role in regulating neuronal signaling and higher brain functions, being involved in various brain diseases. Utilization of small molecules targeting the CaMKIIα hub domain has proved to be a promising strategy for specific CaMKIIα modulation and future therapy. Through an structure-based virtual screening campaign, we herein identified 2-arylthiazole-4-carboxylic acids as a new class of high-affinity CaMKIIα hub ligands.

The World Health Organization has identified multidrug-resistant bacteria as a serious global health threat. Gram-negative bacteria are particularly prone to antibiotic resistance, and their high rate of antibiotic resistance has been suggested to be related to the complex structure of their cell membrane. The outer membrane of Gram-negative bacteria contains lipopolysaccharides that protect the bacteria against threats such as antibiotics, while the inner membrane houses 20-30% of the bacterial cellular proteins.

The microbial aminotransferase enzyme DapC is vital for lysine biosynthesis in various Gram-positive bacteria, including . Characterization of the enzyme's conformational dynamics and identifying the key residues for ligand binding are crucial for the development of effective antimicrobials. This study employs atomistic simulations to explore and categorize the dynamics of DapC in comparison to other classes of aminotransferase.
