The influence of different application methods on UV protective properties of white and dyed cotton functionalized with ZnO nanoparticles (nano-ZnO) was investigated. The methods differ in application procedure, time of treatment and auxiliaries used in the treating bath. The ultraviolet protection factor (UPF) was determined for untreated and functionalized samples. The presence of nano-ZnO on fibres was investigated using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The content of Zn was determined with energy-dispersive X-ray spectroscopy (EDS) and inductively coupled plasma mass spectrometry (ICP-MS). Dynamic light scattering (DLS) was used for particle size measurements in the prepared solutions. The results show that UV protection of cotton increases with a higher content and uniform distribution of nano-ZnO on the samples and that dyeing increases the loading capacity of cotton towards nano-ZnO. One of the methods (Method IV) gave remarkable results giving cotton an excellent UV protection whether it was dyed or not.

Background: Mental health problems in university students are associated with many negative outcomes, yet there is a gap between need and timely access to help. Single-session interventions (SSIs) are designed to be scalable and accessible, delivering core evidence-based intervention components within a one-off encounter.
Objective: COMET (Common Elements Toolbox) is an online self-help SSI that includes behavioral activation, cognitive restructuring, gratitude, and self-compassion.

This study aimed to optimize the ultrasonic/microwave-assisted extraction (UAME) technique of polysaccharides (EAP-UM) by response surface methodology (RSM). The optimum conditions include: solid-liquid ratio of 1:23 g/mL, ultrasonic power of 252 W, microwave power of 417 W, and extraction time of 11 min. Under these conditions, the yield of polysaccharides reached 7.

Atrial fibrillation (AF) burden is strongly associated with an increased risk of stroke, which, in most cases, can be prevented through earlier detection of AF and the timely initiation of anticoagulation therapy. Smartphone devices can provide a simple, non-invasive, cost-effective early AF detection solution. PubMed, Embase, and Scopus databases were searched for studies comparing smartphone-based photoplethysmography (PPG) with standard electrocardiogram for AF detection.

Objective: Although artificial intelligence (AI) is increasingly being applied to ultrasound imaging in gynecology, efforts to synthesize the available evidence have been inadequate. The aim of this systematic review was to summarize and evaluate the literature on the role of AI applied to ultrasound imaging in benign gynecological disorders.
Methods: Web of Science, PubMed and Scopus databases were searched from inception until August 2024.

CT chest scans are commonly performed worldwide, either in routine clinical practice for a wide range of indications or as part of lung cancer screening programs. Many of these scans detect lung nodules, which are small, rounded opacities measuring 8-30 mm. While the concern about nodules is that they may represent early lung cancer, in screening programs, only 1% of such nodules turn out to be cancer.
