Elevated concentrations of arsenic in drinking water are common worldwide, however, little is known about the presence of other potentially toxic elements. We analyzed 31 different elements in drinking water collected in San Antonio de los Cobres and five surrounding Andean villages in Argentina, and in urine of the inhabitants, using ICP-MS. Besides confirmation of elevated arsenic concentrations

Background: Despite considerable racial and geographical differences in human phenotypes and in the incidence of diseases that may be associated with sex steroid action, there are few data concerning variation in sex steroid levels among populations. We designed an international study to determine the degree to which geography and race influence sex steroid levels in older men. Methods: Using mass

BACKGROUND: Breast milk provides infants with complete nutrition for immune development and protection against childhood diseases and associated mortality. Early initiation of breastfeeding (EIBF) aids in providing colostrum to newborns, providing protection against infection, and improving newborn and infant survival. Although Simiyu reported the lowest prevalence of EIBF in Tanzania, no study ha

Petrochemical producers both rely upon and generate some of the most problematic substances in the current age of socioecological crisis: fossil fuels and plastics. With mounting calls to cap fossil fuel extraction as well as plastics production, the industry appears to be caught between a rock and a hard place. Nonetheless, betting on continuously increasing global plastic demand, petrochemical p

Limited knowledge of African inequality trajectories hampers our understanding of the drivers of heterogenous inequality outcomes in Africa today, and leads to major omission in debates about global inequality. In recent years, African economic history has advanced towards the reconstruction of full income distributions of African economies using 'social tables'. In this paper, we take stock of th

Hand-arm vibration injury is a well-known occupational disorder that affects many workers globally. The diagnosis is based mainly on quantitative psychophysical tests and medical history. Typical manifestations of hand-arm vibration injury entail episodes of finger blanching, Raynaud's phenomenon (RP) and sensorineural symptoms from affected nerve fibres and mechanoreceptors in the skin. Differenc

Batrachochytrium dendrobatidis (Bd) is a fungal pathogen that has decimated amphibian populations worldwide for several decades. We examined the changes in gene expression in response to Bd infection in two populations of the common toad, Bufo bufo, in a laboratory experiment. We collected B. bufo eggs in southern and northern Sweden, and infected the laboratory-raised metamorphs with two strains

The onset of the Holocene was associated with a global temperature increase, which led to a rise in sea levels and isolation of the last surviving population of woolly mammoths on Wrangel Island. Understanding what happened with the population's genetic diversity at the time of the isolation and during the ensuing 6000 years can help clarify the effects of bottlenecks and subsequent limited popula

BACKGROUND: Acute kidney injury (AKI) following cardiac surgery is a well-described phenomenon, usually associated with hemodynamic changes ultimately leading to ischemic injury to the kidneys. In this study, we assessed the occurrence of AKI in a cohort of patients undergoing elective cardiac surgery at a single center.METHODS: Patients undergoing elective cardiac surgery (coronary artery bypass

High-frequency in situ measurements at Gosan (Jeju Island, Korea) during November 2007 to December 2008 have been combined with interspecies correlation analysis to estimate national emissions of halogenated compounds (HCs) in East Asia, including the chlorofluorocarbons (CFCs), halons, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6),

Enzymes, as efficient and environmentally friendly catalysts, have gainedsignificant scientific and industrial attention for their mild operating conditions,high substrate selectivity and reusability when immobilized. Among them, lipasesdominate the global industrial enzyme market, catalyzing various reactions with afocus on substrate specificity and selectivity. This thesis investigates theoptimi

Complex metabolic diseases due to overnutrition such as obesity, type 2 diabetes, and fatty liver disease are a major burden on the healthcare system worldwide. Current research primarily focuses on disease endpoints and trying to understand underlying mechanisms at relatively late stages of the diseases, when irreversible damage is already done. However, complex interactions between physiological

BACKGROUND Advanced Therapy Medicinal Products (ATMPs) for human use have advanced globally with the rapid adoption of Chimeric Antigen Receptor T-cell (CAR-T) therapies in haemato-oncology. CAR-T cell therapy and ATMPs have unique, significant acute and chronic toxicities, and appropriate patient care is crucial. Significant challenges, including the need for nurse education and training, accompa

Road traffic accidents cause nearly 1.3 million deaths and around 50 million injuries each year globally. Most organisations generate travel and transport, and influence thereby traffic safety. In Sweden, 47 percent of fatal accidents in road traffic are work-related, and 36 percent are linked to a procured transport service. Effective approaches to managing traffic safety in organisations have no

This article explores the paradox of corporations using social and environmental justice concerns to market products that are themselves made in conditions of environmental and social injustice, most often in the Global South. The effects of the fashion industry on people is two-pronged: 1) the unsafe and exploitative conditions under which many garment workers operate, and 2) the severe and harmf

Large-scale science research facilities, such as those for investigation into the smallest components of physical matter, often consist of buildings with quite extraordinary features as regards shape and scale. These architectures are semiotically interesting in several ways: they have extraordinary outer forms that reflect the their inner activities; they require forms of mediation and planning t

The interplay between spin-orbit coupling and structural inversion symmetry breaking in solids has generated much interest due to the nontrivial spin and magnetic textures which can result. Such studies are typically focused on systems where large atomic number elements lead to strong spin-orbit coupling, in turn rendering electronic correlations weak. In contrast, here we investigate the temperat
