The main aim of this work is to analyze the impact of the National Minimum Wage (NMW) on wealth redistribution in Spain during the 2001-2021 period. This research addresses a fundamental question: Does increasing the minimum wage effectively reduce income inequality and contribute to a more equitable wealth distribution without negatively impacting overall economic growth and employment? Using a complete statistical census provided by the Spanish Tax Administration Agency, this study examines how the increase in th [...]

Carbon capture and storage (CCS) technology mitigates greenhouse gas (GHG) emissions. However, comprehensive studies assessing the sustainability of coal-based power generation (CBPG) with CCS remain limited. This study focuses on developing comparative sustainability indicators across the entire life cycle of CBPG integrated with CCS technology. Sixty-six pathways were analyzed after establishing five sustainability indicators for each. These indicators were standardized per megawatt-hour (MWh) of energy, encompas [...]

The biochemical properties of metal complexes containing benzo hydrazide Schiff base have been reported by numerous researchers worldwide in various ways. In this work, the evaluation of biochemical roles of the metal complexes with benzo hydrazide Schiff base activity as anti-gram positive and gram-negative bacteria, as well as antifungal agents, were observed. The use of various techniques, including the induced fit docking methodology, the density functional theory method, and pharmacokinetics investigations wit [...]

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 [...]

Berberine is an alkaloid chemical found in plants, including Berberidaceae, Coptis rhizomes, and Hydrastis canadensis. Berberine has been shown to improve insulin sensitivity, promote adipocyte loss, and is associated with higher levels of skeletal muscle protein synthesis. The purpose of this study was to examine berberine’s dose-dependent effects on C2C12 myoblast proliferation and 3T3L1 adipocyte differentiation. Cells were grown out over 3 weeks, and once confluent at 90%, they were treated with berberine to ex [...]

Dietary and lifestyle choices have considerable effects on skin health, which reflects overall well-being. Nutrition is now a key component in the management and prevention of skin-related issues due to the increasing incidence of dermatological disorders and the growing demand for anti-aging remedies. This review examines the complex relationship between nutrition, diet, and skin aging, with a focus on the functions of probiotics, vitamins, minerals, essential fatty acids, and antioxidants. Evidence suggests that [...]

Excess dietary calories relative to energy expenditure lead to increased body weight, a problem now widely described as an epidemic because of its association with numerous disease states. Although free digestible sugars are to the most extent absorbed relatively easily from foods in healthy individuals, this is not the case for starches; where the physico-chemical properties control the rate and extent of enzymatic hydrolysis in the small intestine. Thus, even when the quantity of starch in a food product is known [...]

Thyroid disorders are an actual global health concern requiring diverse therapeutic strategies. Potentilla alba (P. alba), commonly known as White cinquefoil, has been used in folk medicine for its rich composition of microelements and pharmacologically essential phytocompounds. It has now also gained recognition in evidence-based medicine for its potential to treat thyroid dysfunction, particularly hypothyroidism and nodular goiter. However, the complicated composition of P. alba extracts makes it difficult to pre [...]

Climate change, biodiversity loss, and malnutrition are interconnected global challenges that increasingly threaten food security, healthy diets, and environmental sustainability. Current dietary patterns characterized by high consumption of ultra-processed foods have negative environmental impacts, including increased greenhouse gas emissions, water and land use, malnutrition, and biodiversity loss. Sustainable and healthy diets that emphasize plant-based foods, minimize food waste, and promote ecosystem conservat [...]
