Laser-Induced Metal-Organic Framework-Derived Flexible Electrodes for Electrochemical Sensing.

The successful development of a metal-organic framework (MOF)-derived Co/CoO/C core-shell composite integrated into laser-induced graphitic (LIG) carbon electrodes for electrochemical sensing is reported. The sensors are fabricated via a direct laser scribing technique using a UV laser (355 nm wavelength) to induce the photothermolysis of rationally selected ZIF-67 into the LIG matrix. Electrochemical characterization reveals that the incorporation of the laser-scribed ZIF-67-derived composite on the electrode surface reduces the impedance more than 100 times compared with bare LIG sensors.

Frontiers in Pulmonary Hypertension: A Comprehensive Insight of Etiological Advances.

Pulmonary hypertension (PH) is a severe, progressive disorder characterized by elevated pulmonary arterial pressure, leading to right ventricular failure and increased mortality. Despite advancements in management, the median survival for PH patients remains 5-7 years, with an inhospital mortality rate of approximately 6%. The core pathological feature of PH is pulmonary vascular remodeling (PVR), a multifactorial process involving endothelial dysfunction, inflammation, and aberrant immune responses.

Immunomodulatory Roles of Mesenchymal Stem Cell-derived Extracellular Vesicles: A Promising Therapeutic Approach for Autoimmune Diseases.

Autoimmune diseases pose a significant challenge due to their complex pathogenesis and rising prevalence. Traditional therapies are often limited by systemic side effects, immunosuppression, and lack of long-term efficacy. Mesenchymal stem cells (MSCs) have demonstrated immunomodulatory properties, primarily through the secretion of extracellular vesicles (EVs), which are now recognized as potent mediators of immune regulation.

Antibiofilm and Antiquorum Sensing Potential of Pheretima posthum.

Antibiotic resistance is a world wide problem mainly in developing countries. In this work, coelomic fluid (PCF) and paste (PBP) of Pheretima posthuma was assessed for its potential as antibiofilm and anti-quorum sensing (QS) agent against pathogenic bacterial biofilms. PCF and PBP were extracted and biofilm formation time kinetics was examined using crystal violet staining method by utilizing four bacterial isolates in bispecies biofilm (06 combinations; MH5-MH10) and multi species biofilms (05 combinations; MH11-MH15).

Hybrid polysaccharide film infused with polyoxometalates for inkless printing and solar ultraviolet sensing.

Inkless paper made from photochromic materials has garnered significant interest owing to its potential to reduce both ink and paper pollution during production. In this research, we synthesized a dual-material film (EC-PVP/PGMEA/PMoA) and conducted a detailed investigation of its photochromic response to visible light and its microstructural properties. Initially, the film appeared as a translucent yellow, but upon exposure to visible light, it shifted to blue with a maximum absorption peak of 2.
