Clinical and Genetic Determinants of Progression of Type 2 Diabetes: A DIRECT Study
OBJECTIVETo identify the clinical and genetic factors that explain why the rate of diabetes progression is highly variable between idividuals following diagnosis of type 2 diabetes.RESEARCH DESIGN AND METHODSWe studied 5,250 patients with type 2 diabetes using comprehensive electronic medical records in Tayside, Scotland, from 1992 onward. We investigated the association of clinical, biochemical,
Increase of beta-Lactam-Resistant Invasive Haemophilus influenzae in Sweden, 1997 to 2010
The proportions of Haemophilus influenzae resistant to ampicillin and other beta-lactam antibiotics have been low in Sweden compared to other countries in the Western world. However, a near-doubled proportion of nasopharyngeal Swedish H. influenzae isolates with resistance to beta-lactams has been observed in the last decade. In the present study, the epidemiology and mechanisms of antimicrobial r
Food intake of individuals with and without diabetes across different countries and ethnic groups
Background/Objectives: Given the importance of nutrition therapy in diabetes management, we hypothesized that food intake differs between individuals with and without diabetes. We investigated this hypothesis in two large prospective studies including different countries and ethnic groups. Subjects/Methods: Study populations were the European Prospective Investigation into Cancer and Nutrition Stu
Sources and properties of Amazonian aerosol particles
This review provides a comprehensive account of what is known presently about Amazonian aerosol particles and concludes by formulating outlook and priorities for further research. The review is organized to follow the life cycle of Amazonian aerosol particles. It begins with a discussion of the primary and secondary sources relevant to the Amazonian particle burden, followed by a presentation of t
Type I interferon-mediated skewing of the serotonin synthesis is associated with severe disease in systemic lupus erythematosus.
Serotonin, a highly pro-inflammatory molecule released by activated platelets, is formed by tryptophan. Tryptophan is also needed in the production of kynurenine, a process mediated by the type I interferon (IFN)-regulated rate-limiting enzyme indoleamine 2,3-dioxygenase (IDO). The aim of this study was to investigate levels of serotonin in patients with the autoimmune disease systemic lupus eryth
Mendelian randomization of blood lipids for coronary heart disease
Aims To investigate the causal role of high-density lipoprotein cholesterol (HDL-C) and triglycerides in coronary heart disease (CHD) using multiple instrumental variables for Mendelian randomization. Methods and results We developed weighted allele scores based on single nucleotide polymorphisms (SNPs) with established associations with HDL-C, triglycerides, and low-density lipoprotein cholestero
Longitudinal age-and cohort trends in body mass index in Sweden - a 24-year follow-up study
Background: The aim of this longitudinal study was to analyze whether mean Body Mass Index (BMI), assessed at four occasions, changed within different age groups and birth cohorts over time, i.e., between 1980/81 and 2004/05, after adjustment for possible confounders. Methods: A sample of 2728 men and 2770 women aged 16-71 years at study start were randomly drawn from the Swedish Total Population
Dppa5 improves hematopoietic stem cell activity by reducing endoplasmic reticulum stress.
Developmental pluripotency-associated 5 (Dppa5) is an RNA binding protein highly expressed in undifferentiated pluripotent stem cells. Here, we demonstrate that Dppa5 is a regulator of hematopoietic stem cells (HSCs) that critically governs reconstitution capacity after bone marrow transplantation. Ectopic expression of Dppa5 followed by in vitro culture robustly increased HSC reconstitution level
Emissions from soy biodiesel blends: A single particle perspective
Biodiesel has recently reemerged as a common fuel. However, emissions from biodiesel combustion have been studied in much less detail than those from traditional petroleum-based diesel. In this experiment, emissions from the combustion of different fuel blends (BOO, B02, B20, B99, where the number after B indicates the percentage, by volume, of biodiesel in the fuel) in a VW TDi engine were analyz
Genetic Predictors of Weight Loss and Weight Regain After Intensive Lifestyle Modification, Metformin Treatment, or Standard Care in the Diabetes Prevention Program
OBJECTIVE-We tested genetic associations with weight loss and weight regain in the Diabetes Prevention Program, a randomized controlled trial of weight-loss inducing interventions (lifestyle and metformin) versus placebo. RESEARCH DESIGN AND METHODS-Sixteen obesity-predisposing single nucleotide polymorphisms (SNPs) were tested for association with short-term (baseline to 6 months) and long-term (
Growth Mechanism of Self-Catalyzed Group III-V Nanowires.
Group III-V nanowires offer the exciting possibility of epitaxial growth on a wide variety of substrates, most importantly silicon. To ensure compatibility with Si technology, catalyst-free growth schemes are of particular relevance, to avoid impurities from the catalysts. While this type of growth is well-documented and some aspects are described, no detailed understanding of the nucleation and t
Liver Fat Content and Hepatic Insulin Sensitivity in Overweight Patients With Type 1 Diabetes
Objectives: Patients with type 1 diabetes mellitus (T1DM) lack the portal/peripheral insulin gradient, which might diminish insulin stimulation of hepatic lipogenesis and protect against development of nonalcoholic fatty liver disease (NAFLD). We compared liver fat content and insulin sensitivity of hepatic glucose production and lipolysis between overweight T1DM patients and nondiabetic subjects.
Fruit and vegetable intake and type 2 diabetes: EPIC-InterAct prospective study and meta-analysis
Fruit and vegetable intake (FVI) may reduce the risk of type 2 diabetes (T2D), but the epidemiological evidence is inconclusive. The aim of this study is to examine the prospective association of FVI with T2D and conduct an updated meta-analysis. In the European Prospective Investigation into Cancer-InterAct (EPIC-InterAct) prospective case-cohort study nested within eight European countries, a re
Plasma Elaidic Acid Level as Biomarker of Industrial Trans Fatty Acids and Risk of Weight Change: Report from the EPIC Study.
Few epidemiological studies have examined the association between dietary trans fatty acids and weight gain, and the evidence remains inconsistent. The main objective of the study was to investigate the prospective association between biomarker of industrial trans fatty acids and change in weight within the large study European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.
Isocaloric substitution of carbohydrates with protein: the association with weight change and mortality among patients with type 2 diabetes.
The health impact of dietary replacement of carbohydrates with protein for patients with type 2 diabetes is still debated. This study aimed to investigate the association between dietary substitution of carbohydrates with (animal and plant) protein and 5-year weight change, and all-cause and cardiovascular (CVD) mortality risk in patients with type 2 diabetes.
Genetic and epigenetic catalysts in early-life programming of adult cardiometabolic disorders.
Evidence has emerged across the past few decades that the lifetime risk of developing morbidities like type 2 diabetes, obesity, and cardiovascular disease may be influenced by exposures that occur in utero and in childhood. Developmental abnormalities are known to occur at various stages in fetal growth. Epidemiological and mechanistic studies have sought to delineate developmental processes and
Organic compounds in aerosols from selected European sites - Biogenic versus anthropogenic sources
Atmospheric aerosol samples from a boreal forest (Hyytiala, April 2007), a rural site in Hungary (K-puszta, summer 2008), a polluted rural area in Italy (San Pietro Capofiume, Po Valley, April 2008), a moderately polluted rural site in Germany located on a meadow (Melpitz, May 2008), a natural park in Spain (Montseny, March 2009) and two urban background locations (Zurich, December 2008, and Barce
Digested wheat gluten inhibits binding between leptin and its receptor
Background: Leptin resistance is considered a primary risk factor for obesity. It has been hypothesized that dietary cereal grain protein could cause leptin resistance by preventing leptin from binding to its receptor. Non-degraded dietary wheat protein has been found in human serum at a mean level of 41 ng/mL. Here, we report our findings from testing whether enzymatically digested gluten from wh
Estimation of Daily Energy Expenditure in Pregnant and Non-Pregnant Women Using a Wrist-Worn Tri-Axial Accelerometer
Background: Few studies have compared the validity of objective measures of physical activity energy expenditure (PAEE) in pregnant and non-pregnant women. PAEE is commonly estimated with accelerometers attached to the hip or waist, but little is known about the validity and participant acceptability of wrist attachment. The objectives of the current study were to assess the validity of a simple s
