This report describes a new integrated rigid cystoscope which has been designed for diagnostic and therapeutic cystoscopy under local anaesthesia. The small external diameter (17.5 F) and large instrument channel permit maximum irrigant flow and operating potential whilst causing minimum discomfort to the patient. We believe this instrument to be a practical alternative to conventional cystoscopes, including the fibreoptic cystoscope.

Nanobodies or variable antigen-binding domains (VH) derived from heavy chain-only antibodies (HcAb) occurring in the Camelidae family offer certain superior physicochemical characteristics like enhanced stability, solubility, and low immunogenicity compared to conventional antibodies. Their efficient antigen-binding capabilities make them a preferred choice for next-generation small biologics. In the present work, we design an anti-SARS-CoV-2 bi-paratopic nanobody drug conjugate by screening a nanobody database.

Unlabelled: is an acid-fast, aerobic, non-motile, and biofilm-forming bacterium. The increasing prevalence of mycobacterial infections makes it necessary to find new methods to combat the resistance of bacteria to conventional antibiotics. is an emerging pathogen that is intrinsically drug resistant due to several factors, including an impermeable cell envelope, drug efflux pumps, target-modifying enzymes, and the ability to form thick, robust biofilms.

We report the reversible redox-controlled DNA condensation using a simple dicationic diphenylalanine derivative which contains a disulfide unit as linker. Despite the conventional belief that DNA condensing agents require a charge of +3 or higher, this dicationic molecule functions below its critical aggregation concentration, representing a non-canonical DNA condensing agent. The interaction with DNA of the studied compound combines electrostatic effects with hydrophobic/stacking interactions provided with the diphenylalanine moiety.

Tuberculosis (TB), a leading infectious disease caused by the pathogen , poses a significant treatment challenge due to its unique characteristics and resistance to existing drugs. The conventional treatment regimens, which are lengthy and involve multiple drugs, often result in poor patient adherence and subsequent drug resistance, particularly with multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains. This highlights the urgent need for novel anti-TB therapies and new drug targets.

Tear trough deformity (TTD) is a significant cosmetic concern, with current treatments relying primarily on invasive injectable fillers, which are costly and carry risks of complications. Despite the widespread use of hyaluronic acid (HA) in cosmetic applications, its poor dermal permeation has limited the development of effective topical fillers for TTD.This study aim to develop and evaluate a novel hyaluronic acid nanogel (nanofiller, NF) as a non-invasive topical filler for TTD.
