Objective: Patients with chronic kidney disease suffer from immune dysfunction, increasing susceptibility to infections. The aim of the study was to investigate air contamination with respiratory viruses in a dialysis unit at a quaternary hospital using molecular detection techniques and to analyze airflow dynamics through computational fluid dynamics (CFD) simulations for a comprehensive assessment of air transmission risks.
Methods: We conducted dialysis unit air sampling using AerosolSense™ samplers.
Neuronal Imaging at 8-Bit Depth to Combine High Spatial and High Temporal Resolution With Acquisition Rates Up To 40 kHz.

A challenge in neuroimaging is acquiring frame sequences at high temporal resolution from the largest possible number of pixels. Measuring 1%-10% fluorescence changes normally requires 12-bit or higher bit depth, constraining the frame size allowing imaging in the kHz range. We resolved Ca or membrane potential signals from cell populations or single neurons in brain slices by acquiring fluorescence at 8-bit depth and by binning pixels offline, achieving unprecedented frame sizes at kHz rates.

Light induced release of cisplatin from Pt(IV) prodrugs is a promising tool for precise spatiotemporal control over the antiproliferative activity of Pt-based chemotherapeutic drugs. A combination of light-controlled chemotherapy (PACT) and photodynamic therapy (PDT) in one molecule has the potential to overcome crucial drawbacks of both Pt-based chemotherapy and PDT via a synergetic effect. Herein we report green-light-activated Pt(IV) prodrug GreenPt with BODIPY-based photosentitizer in the axial position with an incredible high light response and singlet oxygen generation ability.

The emergence of multidrug-resistant microbial strains poses a significant challenge to global public health. In response, researchers have been exploring innovative antimicrobial agents with enhanced efficacy and novel mechanisms of action. One promising approach involves the synthesis of hybrid molecules combining azetidinone and azole moieties, capitalizing on the respective antimicrobial properties of both structural elements.

Background: Curcumin is a polyphenolic compound derived from the food spice turmeric that has received interest from the medical and scientific world for its role in the management of several conditions. Clinical studies, in humans, have shown that ingested Curcumin is safe even at high doses (12 g/day), but it has poor bioavailability primarily due to poor absorption and rapid metabolism and elimination. Several strategies have been implemented to improve the bioavailability of Curcumin, for example, the combination of piperine in a complex with Curcumin, or the usage of formulations with phospholipid or liposomal complexes.
