During the last 20 years, several regions in Central America and Mexico have seen a dramatic increase of a rapidly progressive chronic kidney disease, unexplained by diabetes and hypertension.(1-3) This regional epidemic of chronic kidney disease of unknown origin (CKDu) is also being referred to as the Mesoamerican nephropathy or MeN.(4) It has been estimated that this largely unknown epidemic ha

A combined two-cell reaction system containing Gluconobacter oxydans and Ralstonia eutropha was evaluated with regard to asymmetric ketone reduction using H(2) as the reductant. Whole cells permeabilized by EDTA/toluene were used, and synthesis was performed in a biphasic aqueous/organic reaction medium. The two-cell system was compared with a system in which G. oxydans alone was used for both ket

Background. Founded in 1995, the Swedish Rectal Cancer Registry (SRCR) is frequently used for rectal cancer research. However, the validity of the registry has not been extensively studied. This study aims to validate a large amount of registry data to assess SRCR quality. Material and methods. The study comprises 906 patients treated with major abdominal surgery registered in the SRCR between 199

Abstract in Undetermined The aim of this study was to achieve a method to perform detailed characterization and human exposure studies of nanosized and nanostructured aerosol particles. The source chosen was mild steel, active gas, arc welding fume. The setup consisted of a generation chamber, where welding can be performed, connected to an airtight stainless steel 22 m(3) exposure chamber. Instru

PURPOSE: To analyze the visual outcome after cataract surgery. SETTING: Cataract surgery clinics in 15 European countries. DESIGN: Database study. METHODS: Data were drawn from case series of cataract extractions reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery database. These data were entered into the database via the Web by surgeons or by transfer from e

Previous research has shown that the Redesigning Daily Occupations programme reduced the degree of sick leave and increased return to work rates among women on sick leave for stress-related disorders when compared with "care as usual". To further investigate the Redesigning Daily Occupations intervention, this study explored changes in the work situation from baseline to a 12-month follow-up in th

The study explored the utility of four-point preprandial glucose self-monitoring to calculate several indices of glycemic control and variability in a study adding the DPP-4 inhibitor vildagliptin to ongoing insulin therapy. This analysis utilized data from a double-blind, randomized, placebo-controlled crossover study in 29 patients with type 2 diabetes treated with vildagliptin or placebo on top

In order to systematically improve the performance of anion-exchange membranes (AEMs) for alkaline fuel cells, a series of poly(phenylene oxide)s (PPOs) was tethered with cationic alkyl side chains of different lengths and configurations. PPO was first functionalized with bromomethyl and longer bromoalkyl side chains, respectively, before introducing quaternary ammonium (QA) groups via Menshutkin

Inland waters were recently recognized to be important sources of methane (CH4 ) and carbon dioxide (CO2 ) to the atmosphere, and including inland water emissions in large scale greenhouse gas (GHG) budgets may potentially offset the estimated carbon sink in many areas. However, the lack of GHG flux measurements and well-defined inland water areas for extrapolation, make the magnitude of the poten

BACKGROUND: The method for red marrow dosimetry in radioimmunotherapy, in the absence of specific activity uptake in red marrow, is based on the activity measured in the blood or plasma. The activity concentration ratio of red marrow to blood is then assumed to be constant. The aim of the current study was to determine whether this ratio varies with time after injection. METHODS: Measurements were

Protein D (PD) is a highly conserved 42 kDa surface lipoprotein found in all Haemophilus influenzae, including nontypeable (NT) H. influenzae. PD is involved in the pathogenesis of respiratory tract infections, in the context of which it has been shown to impair ciliary function in a human nasopharyngeal tissue culture model and to augment the capacity to cause otitis media in rats. A likely mecha

The world continues to boil due to capital’s incapacity to resolve its climatic contradictions. Stratospheric Aerosol Injection (SAI), a technological process theorised to instantly reduce global temperatures, has piqued the interest of a now desperate ruling class. Given its worldwide impacts, enormous risks, and capitalist- imperialist reproductive capacities, it is crucial to engage with SAI wh

Development of a new spatially complete and daily continuous lake surface water temperature dataset for Lake Vänern, Sweden Keywords: Physical Geography, Ecosystem Analysis, Remote Sensing, Data Fusion, Reanalysis Product, Lake Surface Water Temperature, Hydrology Lake Surface Water Temperature (LSWT) is an important indicator to monitor changes due to climate change on a regional scale. Changes

Like other African countries, Kenya’ economy and food security is heavily dependent on agriculture. Climate change has led to variability in temperature and precipitation, and extreme weather events such as droughts and floods, all of which can significantly impact crop productivity and food security in the long-term. Furthermore, water scarcity poses a critical challenge for Kenya, particularly i

The carbon intensity is an important metric that provides a clear measure of the environmental impact associated with the electricity use. Carbon intensity of electricity use is differentiated into CO₂ equivalents per kilowatt-hour, which standardises the measurement by expressing the emissions of various greenhouse gases in terms of the equivalent amount of CO₂ based on their global warming poten

Denna rapport utforskar konceptet undvikna utsläpp, även kallat Scope 4-utsläpp, som en del av företags hållbarhetsrapportering- och kommunikation. Med fokus på PowerCell Group, en leverantör av vätgasdrivna bränsleceller, undersöker studien hur Scope 4-utsläpp kan integreras i hållbarhetsrapportering och vilka möjligheter och utmaningar detta innebär. Undvikna utsläpp refererar till de minskningThis thesis explores the concept of Scope 4 emissions, also known as avoided emissions, within corporate sustainability reporting. With a focus on PowerCell Group, a provider of hydrogen fuel cell solutions, this study investigates the integration of avoided emissions reporting, assessing both the potential benefits and the challenges associated with this practice. Avoided emissions refer to redu
