Development and Content Validity of a Questionnaire on Peripheral Intravenous Catheter Maintenance and Knowledge of Nursing Professionals Regarding Best Practices.

The aims of this study were to develop a questionnaire on peripheral intravenous catheter (PIVC) maintenance, evaluate its content validity, and assess factors influencing the level of knowledge of nursing professionals regarding best practices.The study was conducted in 3 stages: (1) development of a questionnaire on PIVC maintenance; (2) content validity assessment by experts with assessment of comprehensiveness, relevance, and clarity; and (3) application of the questionnaire to 1493 nursing professionals. Relationships between personal characteristics and knowledge levels were evaluated.

Mechanochemical Deracemization: A Sustainable Approach to Enantiopurity.

We introduce mechanochemical deracemization (MCDR) as a novel strategy for obtaining enantiopure compounds. This study demonstrates the successful transposition of six archetypical deracemization reactions from a solvent-based to a solvent-minimized ball milling environment. The scope includes a ketone, isoindolinones, imines, an ester, and an inorganic compound, all of which deracemized successfully.

Performance and quality of eggs of laying hens fed with Moringa Oleifera leaf flour.

The objective of this study was to evaluate the performance of commercial laying hens fed with different levels of Moringa oleifera leaf meal in their diet. For this purpose, 150 laying hens of the Dekalb White lineage, at 62 weeks of age, and with an initial average weight of 1.458 kg ± 8.

Abiotic Factors Modulating Metabolite Composition in Brown Algae (Phaeophyceae): Ecological Impacts and Opportunities for Bioprospecting of Bioactive Compounds.

Brown algae are vital structural elements and contributors to biodiversity in marine ecosystems. These organisms adapt to various environmental challenges by producing primary and secondary metabolites crucial for their survival, defense, and resilience. Besides their ecological role, these diverse metabolites have potential for biotechnological applications in industries including pharmaceuticals, cosmetics, and food.

Evaluation of Performance and Longevity of Ti-Cu Dry Electrodes: Degradation Analysis Using Anodic Stripping Voltammetry.

This study aimed to investigate the degradation of dry biopotential electrodes using the anodic stripping voltammetry (ASV) technique. The electrodes were based on Ti-Cu thin films deposited on different polymeric substrates (polyurethane, polylactic acid, and cellulose) by Direct Current (DC) magnetron sputtering. TiCu thin films (chemical composition of 25.
