Mechanism and growth kinetics of hexagonal TiO nanotubes with an influence of anodizing parameters on morphology and physical properties.

Hexagonal TiO nanotubes (hTNTs) mimic a honeycomb structure, indicating their high potential as implantable materials due to their superior mechanical, chemical, and biological properties. However, the fabrication of hTNTs with a hexagonal base and six rectangular sides poses significant challenges, underscoring the importance of this research. This study developed a novel sonoelectrochemical method for synthesizing uniform hTNTs and evaluated the influence of anodizing parameters on their morphology.

Follow-up assessment of the microvascular function in patients with long COVID.

Long COVID is a complex pathophysiological condition. However, accumulating data suggests that COVID-19 is a systemic microvascular endothelial dysfunction with different clinical manifestations. In this study, a microvascular function was assessed in long COVID patients (n = 33) and healthy controls (n = 30) using flow-mediated skin fluorescence technique (FMSF), based on measurements of nicotinamide adenine dinucleotide fluorescence intensity during brachial artery occlusion (ischemic response, IR) and immediately after occlusion (hyperemic response, HR).

Electrochemical and Mechanical Properties of Hexagonal Titanium Dioxide Nanotubes Formed by Sonoelectrochemical Anodization.

This study aimed to investigate the fabrication and characterization of hexagonal titanium dioxide nanotubes (hTNTs) compared to compact TiO layers, focusing on their structural, electrochemical, corrosion, and mechanical properties. The fabrication process involved the sonoelectrochemical anodization of titanium foil in various electrolytes to obtain titanium oxide layers with different morphologies. Scanning electron microscopy revealed the formation of well-ordered hexagonal TNTs with diagonals in the range of 30-95 nm and heights in the range of 3500-4000 nm (35,000-40,000 Å).

Shedding light on the problem: Influence of the radiator power, source-sample distance, and exposure time on the performance of UV-C lamps in laboratory and real-world conditions.

Effective surface disinfection is crucial for preventing the spread of pathogens in hospitals. Standard UltraViolet-C (UV-C) lamps have been widely used for this purpose, but their disinfection efficiency under real-world conditions is not well understood. To fill this gap, the influence of the power of the ultraviolet radiator, source-sample distance, and exposure time on the performance of UV-C lamps against Escherichia coli and Staphylococcus epidermidis were experimentally determined in the laboratory and hospital.

Association between cyberchondria and the use of complementary and alternative medicine (CAM) - a cross-sectional study.

Introduction And Objective: Cyberchondria has been described relatively recently as a behaviour characterized by excessive Internet searching for medical information related to increasing levels of health anxiety. Complementary and alternative medicine (CAM) refers to a broad set of health care practices that are not part of a country's traditional or conventional medicine, and are not fully integrated into the dominant health care system The aim of this study is to evaluate the relationship between cyberchondria and the use of complementary and alternative medicine.

Material And Methods: A cross-sectional study was conducted from 25 April - 25 December 2022.
