In-silico study of molecular adaptations in halophilic Cas9.

This study explores the structural adaptations of the CRISPR-Cas9 system in halophilic bacteria, focusing on Cas9 protein of halophilic bacterium Salicibibacter cibi. Protein sequences were analysed using different tools such as ExPASy ProtParam for different physicochemical properties, PONDR web server for disordered regions, and InterPro server and WebLogo for domains. Protein structures were generated using the AlphaFold database, and the quality of the modelled structure was checked through PROCHECK.

Hemangioma of the Mitral Valve and Aortomitral Curtain in an Adolescent.

A hemangioma of the mitral valve and aortomitral curtain was incidentally discovered in an adolescent. The lesion was surgically excised, and the mitral valve was reconstructed with complete preservation of valvular function. Pertinent principles of multimodality imaging-based diagnosis and nuances of operative management of this rare, vascular tumor are discussed.

Targeted NIR Fluorescent Mechanically Interlocked Molecules-Peptide Bioconjugate for Live Cancer Cells Submitochondrial Stimulated Emission Depletion Super-Resolution Microscopy.

Herein, a water-soluble, ultrabright, near-infrared (NIR) fluorescent, mechanically interlocked molecules (MIMs)-peptide bioconjugate is designed with dual targeting capabilities. Cancer cell surface overexpressed αβ integrin targeting two RGDS tetrapeptide residues is tethered at the macrocycle of MIMs-peptide bioconjugate via Cu(I)-catalyzed click chemistry on the Wang resin, and mitochondria targeting lipophilic cationic TPP functionality is conjugated at the axle dye. Living carcinoma cell selective active targeting, subsequently cell penetration, mitochondrial imaging, including the ultrastructure of cristae, and real-time tracking of malignant mitochondria by MIMs-peptide bioconjugate (RGDS)-Mito-MIMs-TPP are established by stimulated emission depletion (STED) super-resolved fluorescence microscopy.
