Waste production is experiencing a significant increase in correlation with the growth of the human population and industrial activities. The kind of waste that is expanding at a rapid rate is known as "e-waste," which stands for electronic waste. In the context of electronic waste, the term refers to the waste produced during the disposal of electronic devices and any other components utilized in making or operating these devices. In the same way that different types of waste occur, electronic waste pollutes the e [...]

Vitamin D, a fat-soluble secosteroid, plays a pivotal role beyond its functions in calcium and bone homeostasis. Emerging evidence suggests its involvement in glucose metabolism and insulin sensitivity, thus influencing the pathophysiology of Type 2 Diabetes Mellitus (T2DM). For the current review, a search was conducted across four major databases: PubMed, Embase, Google Scholar, and Web of Science. The aim was to identify relevant studies and clinical trials, published in English, reporting the mechanistic insigh [...]

This work focuses on designing a control unit for improving Proton Exchange Membrane Fuel Cell (PEMFC) performance powering electric vehicles when operating in variable atmospheric pressure conditions, a current situation in mountainous countries with sudden changes in road altitude. The paper studies and analyzes the PEM fuel cell behavior working with hydrogen supply from a pressurized tank and oxygen input from atmospheric air supply in journeys with continuous variation of road level due to the orography. The w [...]

Generally, in reciprocal translocations there are no gains or losses of genetic material. From the clinical point of view, its primary importance lies in the fact that it can generate errors due to incorrect chromosome segregation during meiosis in carriers. On the other hand, other mutations are less frequent in the genome, specifically in the DNA breakpoints implied in these translocations. In Latin America there are no large-scale reports about this topic. To contribute to the study of reciprocal translocations [...]

Background: Branched-chain amino acids (BCAA) are nutrients with a bitter taste, which causes low compliance in patients who need BCAA supplementation. Moreover, chronic liver disease is frequently complicated by taste impairment. The present study was designed to improve patient noncompliance regarding nutrients in liver disease. Methods: A taste questionnaire was administered to healthy controls, chronic hepatitis patients, and cirrhotic patients. Eleven different flavored powders that can be added to BCAA nutri [...]

Postoperative cognitive dysfunction (POCD) has been observed as a complication after cardiac surgery consistently. The ineffectiveness of current treatments for POCD is causing a search for non-invasive alternatives. The present review aims to consolidate the current understanding of how VR methods effectively facilitate the recovery of cognitive functioning in cardiac surgery patients. To obtain information about the effects of VR technology on cognitive functions, we investigated the PubMed, Scopus, and Web of Sc [...]

Non-celiac gluten sensitivity (NCGS) is a debatable condition that affects less than 6% of children. The absence of specific diagnostic markers and standardized diagnostic procedures make the diagnosis of NCGS challenging, covering patients with different and varied symptoms. Generally, the parents of small and younger children introduce a gluten-free diet (GFD) based on their personal experiences and expectations. Additionally, a “fad component” exists, contributing to the recent rise in the popularity of GFD. Thu [...]

High strength and good conductivity are both critical parameters for copper-based alloys for electrical and other technological applications. This study is aimed to produce copper alloys and metal matrix composites (MMCs) with enhanced physical properties. Cu-Ti-Ni ternary alloys and MMCs samples were sintered at 600 to 700°C using spark plasma sintering (SPS), with a heating rate of 100°C/minutes, uniaxial pressure of 50 MPa, and a holding time of 10 minutes. Scanning electron microscopy (FE-SEM) was used to exami [...]

Research into the uptake profile and usage of Homeopathy has hitherto tended to be buried amongst complementary medicine research. Despite high levels of uptake of homeopathy, and robust numbers of over-the-counter sales of homeopathic products the current evidence evaluating the uptake of homeopathy remains limited on several fronts. The aim of this study is to explore the basic demographic features and characteristics of users of homeopathy services. The setting is a student teaching tele-health facility based in [...]
