The pursuit of efficient and economical catalysts for water splitting, a critical step in hydrogen production, has gained momentum with the increasing demand for sustainable energy. Among the various electrocatalysts developed to date, cobalt oxide (CoO) has emerged as a promising candidate owing to its availability, stability, and catalytic activity. However, intrinsic limitations, including low catalytic activity and poor electrical conductivity, often hinder its effectiveness in electrocatalytic water splitting.

Microplastics (MPs), defined as plastic particles smaller than 5 mm, are increasingly recognized as environmental contaminants with potential health risks. These emerge as breakdown products of larger plastics and are omnipresent in marine, freshwater, and terrestrial ecosystems. They are primarily composed of polymers such as polyethylene, polypropylene, polystyrene, and additives that enhance their performance.

Dental caries, a persistent oral health challenge primarily linked to , extends its implications beyond dental decay, affecting over 4 billion individuals globally. Despite its historical association with childhood, dental caries often persists into adulthood with prevalence rates ranging from 60 to 90% in children and 26 to 85% in adults. Currently, there is a dearth of multiepitope vaccines (MEVs) specifically designed to combat .

Medical students, in particular, must be physically and mentally fit to perform better academically and to treat their patients holistically. Consuming a nutritious diet and maintaining good health requires an adequate understanding of nutrition and related diseases.

EC materials based on ion insertion/extraction mechanisms also present the possibility for energy storage, widening its functionality to the supercapacitor platform. The bi-functional performance of dual-band radiation control and energy storage was achieved by exploiting two earth-abundant metal oxides that could absorb two different spectral regions when electrochemically charged.

The nexus between intestinal parasites and the gut microbiome in IMBD is a dynamic and complex field of study. Several studies have evidenced the capacity of intestinal parasites to modulate the gut microbiome, inducing alterations in microbial diversity, abundance, and metabolic activity.

The synthetic materials' crystalline structure was confirmed by X-ray diffraction (XRD), and its unique marigold-like morphology was observed by field emission scanning electron microscopy (FESEM). The chemical states of the elements were investigated via X-ray photoelectron spectroscopy (XPS).

TEM and SEM images, standard tools in materials science, provide a clear view of the morphology of Cu-MoS. HRTEM analysis, a high-resolution imaging technique, confirms the lattice spacing, lattice plane, and crystal structure of Cu-MoS.

By interfering in the production of antioxidant enzymes such as glutathione peroxidase, thioredoxin reductase and methionine sulfoxide, Se plays a role in reducing the effects of oxidative stress and animal performance.
Objectives: This study aimed to investigate the effect of hydroxy-selenomethionine (OH-SeMet) in the diet of broiler breeder and old broiler breeder roosters on productive performance, reproduction and sperm quality parameters.
Introduction Telemedicine serves as a means of overcoming geographical barriers and increasing access to specialist care. This study focuses on the impact of telemedicine on the early diagnosis and treatment of patients, as well as its effect on patient satisfaction. In addition, the study examines the obstacles and facilitators that influence the implementation of telemedicine.

The weight percentage of g-CN nanoparticles influenced the electrochemical performance of the CoO-g-CN composite. In an aqueous electrolyte, the CoO-g-CN composite electrode, produced with 150 mg of g-CN nanoparticles, revealed remarkable electrochemical performance.

Chemotherapy has recently been recognized as one of such reasons. However, in-depth studies of chemotherapy-induced dormancy are lacking due to the absence of an in vitro human-relevant model tailor-made for such a scenario.

Methods: Review of hospital records was conducted for 56 healthy infants (aged below 6 month) who developed sudden onset of pulmonary arterial hypertension as diagnosed on 2D echocardiography, and were admitted at our institution.
Results: All patients received supportive care and pulmonary vasodilator therapy, whereas those admitted after Sep-tember, 2019 (n=28) received thiamine in addition, as per the institute's protocol.
Cardiospondylocarpofacial syndrome (CSCF; MIM#157800) is a rare condition caused by monoallelic variants in the MAP3K7 gene. The characteristic features of CSCF include growth retardation, facial dysmorphism, carpal-tarsal fusion, dorsal spine synostosis, deafness, inner ear malformation, cardiac septal defect and valve dysplasia. We present here a 20-week-old fetus with cardiospondylocarpofacial syndrome arising from a de novo variant c.
