This study aimed to reveal the evolution and characteristics of the COVID-19 pandemic in high-altitude areas of Perú. An observational, descriptive, retrospective and longitudinal study based on information from the Peruvian Ministry of Health, COVID-19 Situational Room, warning from the National Epidemiology Center, Prevention and Disease Control, and the Panamerican Health Organization (PAHO) was conducted to analyze the occurrence of the COVID-19 pandemic in Perú from the beginning of the pandemic until March 7, [...]

There has been a steady expansion in islet isolation and transplantation activity worldwide. In addition to preparing human islets for transplantation, we have been providing human islets to basic researchers. The aim of this study was to review the activity of distribution of human islets to basic researchers in North America, Europe, and Asia, and to investigate if there are any differences in utilization rate of islets among three continents. We reviewed our islet isolation batch files, donor records, and docume [...]

In this study, by producing bifunctional material, hydrolysis, and supercapacitor applications were investigated. The carbon nanotube-supported Pt catalyst was prepared using the sodium borohydride (NaBH4) reduction. Surface characterization of the synthesized Pt/CNT catalyst was performed using scanning electron microscopy-energy dıstrıbutıon X-ray spectrometer (SEM-EDX), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Hydrolysis experiments were performed after deciding on the appropriate ato [...]

The COVID-19 pandemic has led to unprecedented challenges globally, impacting various aspects of daily life, including education. This study examines the effects of the pandemic on stress levels and substance use among Italian medical students. Two independent surveys were conducted: 388 medical students were interviewed before the epidemic, and 222 medical students a year after the COVID-19 epidemic began. Results revealed significant changes in stress levels, with a reduction in mild stress and an increase in sev [...]

Human skeletal muscle exhibits remarkable plasticity, being responsive to chemical, mechanical, metabolic, and inflammatory stress. When the homeostatic disturbance is below a threshold of significant damage, the muscle responds by modifying metabolic activity, cell size/shape, and structure, thereby normalizing cellular function. If the disturbance causes significant damage, skeletal muscle, along with a precisely choreographed response from the immune system, can regenerate. Very few pathological conditions inhib [...]

The World Health Organization attracted more attention to the positive effects of physical activity (PA) and the adverse effects of stress on the health of older people and, therefore, attracted a more significant number of practitioners. To verify the impact of PA on stress in older people. Observational and analytical research, composed of 690 older people of both genders residing in Brazil, present in street races (as participants or observers), who volunteered to respond to the research protocol consisting of s [...]

Graft rejection, early allograft dysfunction (EAD), and poor diagnostic accuracy are some of the challenges that still need to be addressed, even though liver transplantation (LT) has the potential to help patients with end-stage liver disease (ESLD) significantly. Traditional procedures, such as liver biopsies and liver function tests (LFTs), often fail to identify abnormalities early and with accuracy. Genomic RNA sequencing (RNA-Seq) has recently emerged as a powerful approach for identifying molecular markers o [...]

This research aims at one of the most important economic and environmental problems - the elimination of the consequences in case of emergency spills while cleaning petroleum products. The objectives of the study include the development and production of new biological products and biosorbents based on carbon-oxidizing microorganisms, testing the developed technologies for environmental risk management to eliminate the consequences of emergency petroleum product spills, creating an algorithm for conducting prelimin [...]

The paper presents an overview of recent studies assessing technology-aided strategies aimed at helping people with intellectual and multiple disabilities reach relevant rehabilitation goals. The 16 studies included in the paper addressed four specific rehabilitation goals, that is, (a) performance of functional activities, (b) access to leisure and communication and performance of functional activities, (c) increase of adaptive responses and decrease of problem behavior or inadequate posture, and (d) increase of a [...]

Generally, automobile vehicles discharge specific contaminants into the surrounding environment during operation, which might affect human and reproductive health. Additionally, a more extended period of sitting while driving is linked with the manifestation of heat in the pelvic region, which might also impact the driver’s semen quality. The data on motor traffic pollution, sitting posture duration while driving, and their impact on reproduction was collected by searching various websites. The data on the effects [...]
