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 [...]

Food-system by-products (FSBP), including agricultural by-products, agro-industrial co-products, and food-processing residues, represent an underused source of nutrients and plant secondary compounds with significant potential in ruminant feeding systems. This review synthesized 96 peer-reviewed studies published between 2000 and 2025 on phytochemically rich FSBP in ruminant diets, focusing on composition, rumen fermentation, animal health and performance, product quality, and environmental outcomes. Across the stu [...]

Dietary factors influence chronic inflammation and immune regulation, potentially affecting the onset and activity of rheumatic disease. Red meat, a major source of protein, heme iron, and saturated fat, has been linked to metabolic and inflammatory disorders, yet its role in rheumatic diseases remains unclear. To comprehensively evaluate the relationship between red-meat consumption and major rheumatic diseases—including rheumatoid arthritis (RA), gout, systemic lupus erythematosus (SLE), and other inflammatory or [...]

Selenium (Se) is a key micronutrient integrated into selenoproteins such as glutathione peroxidases (GPx), which are responsible for crucial antioxidant and anti-inflammatory mechanisms. Oxidative stress contributes to the immunopathogenesis and chronic joint damage of rheumatoid arthritis (RA), supporting interest in selenium supplementation as an adjunct therapeutic strategy. This review was based on a structured literature search of major biomedical databases and evaluated six controlled clinical trials involvin [...]

This study was conducted to process frozen yoghurt (FY) from camel milk (CM) flavored with either 5% or 8% banana (B) or dates (D). The mix of FY consists of stirred yoghurt, sugar, Gum Arabic, and banana (Musa lutea) or dates (Phoenix dactylifera). The mix was divided into 4 portions and then each mix was sub-derived into an ice-cream machine and then packed into plastic cups that were stored at -18°C for 5 weeks. The chemical composition and sensory evaluation were conducted weekly. The chemical composition of FY [...]

Enteropathogenic strains of Escherichia coli, like the serotype O157:H7, can cause significant health issues if consumed. Milk and dairy products can serve as a reservoir for the bacteria. Dissemination of multidrug-resistant E. coli through dairy products can become a potential health hazard if consumed. The present study investigates the occurrence of multidrug-resistant E. coli O157:H7 in raw milk obtained from farms and markets around Dhaka, Bangladesh. A Total of 50 milk samples were collected in this study fr [...]

Recommendations for vitamin D supplementation are essential for the prevention and therapy of vitamin D deficiency. However, reliable data remain lacking for children, as most intake recommendations are based on individual studies. This work aimed to obtain reliable data that allow health authorities to re-evaluate recommendations for oral vitamin D uptake in children. We conducted a systematic literature search in MEDLINE/PubMed on vitamin D supplementation in children. All randomized controlled trials (RCTs) publ [...]

Heavy metals are integral parts of our environment, originating initially from the universe and used in the industry, which may contribute to pollution. This book chapter aims to address the impact of heavy metals on the ecosystem and human health. Among the 32 heavy metals, eight belong to the group of essential ones: cobalt, copper, iron, manganese, molybdenum, nickel, selenium, and zinc. They were necessary in physiological amounts for the evolution of flora and fauna, including humans on earth, and are still ne [...]
