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

A lysimeter method was evaluated for its suitability in gas emission studies by studying the effect of temperature on CO2 emissions (dark respiration) from cultivated peat soils. The study was carried out with organic soils from two locations in Sweden, a typical cultivated fen peat with low pH and high organic matter content (Orke) and a more uncommon fen peat with high pH and low organic matter

Objective The purpose of this study was to evaluate the effect of wet clothing removal or the addition of a vapor barrier in shivering subjects exposed to a cold environment with only limited insulation available. Methods Volunteer subjects (n = 8) wearing wet clothing were positioned on a spineboard in a climatic chamber (–18.5°C) and subjected to an initial 20 minutes of cooling followed by 3

A pulse of respiration is induced by rewetting dry soil. Here we study the microbial responses underlying this pulse of respiration when rewetting soil dried for 4-days or 1-year. In the 4-days dried soil, respiration increased to a maximum rate immediately upon rewetting after which it decreased exponentially. In the 1-year dried soil, respiration also increased immediately, but then remained hig

Laminar burning velocities of syngas/air premixed flames, varying with H-2/CO ratio (from 5/95 to 75/25) and N-2 or CO2 dilution rate (from 0% to 60%), were accurately measured using a Teflon coated Heat Flux burner and OH-PLIF based Bunsen flame method. Experiments were carried out at atmospheric pressure and room temperature, with fuel/air equivalence ratios ranging from fuel-lean to fuel-rich.

BACKGROUND: The clinical assessment of axillary lymph nodes status and tumor size is important for the management of patients with breast cancer. The first goal of this study was to determine the accuracy of axillary lymph node status in relation to the presence of metastases as revealed by histopathological examination. The second goal was to compare the tumor size as assessed by physical examina

In many materials it remains a challenge to reveal the nature of magnetic correlations, including antiferromagnetism and spin disorder. Revealing the spin structure in magnetic nanoparticles is further complicated by the large incoherent neutron scattering cross section from water adsorbed at the particle surfaces and by the broadening of diffraction peaks due to the finite crystallite size. Moreo

Adaptation is essential in maintaining stability during balance-challenging situations. We studied, ill standing subjects with eyes open and closed, adaptive responses of the anteroposterior head, shoulder, hip and knee movements: gastrocnemius and tibialis anterior EMG activity and anteroposterior body Posture when proprioceptive information from the neck or calf muscles underwent vibratory pertu

Energy policies in China, the world’s largest energy consumer, are an important factor in shaping the 41 global energy system. While scholars agree that energy security is a major driver of China’s energy 42 policies, there is insufficient understanding of what exactly constitutes China’s energy security from the 43 policy perspective. We apply recent insights from the Global Energy Assessment, pa

BACKGROUND AND PURPOSE: Distal radius fractures are most often treated nonoperatively, but sometimes they are treated surgically when deemed unstable. Based on the literature, a consensus protocol for treatment has been developed in southern Sweden to aid clinicians in their decision making. We evaluated the results of this protocol prospectively using a validated outcome instrument (DASH) in a la

The purpose of this study was to determine the incidence of aerococcal bacteraemia in the MALDI-TOF MS-era, to describe the clinical presentation and to determine the MIC values of aerococci for ten antibiotics. Aerococci in blood cultures were identified through searches in the laboratory database for the years 2012-2014. MALDI-TOF MS, sequencing of the 16S rRNA gene and a PYR test were used for

Background: Exhaled breath temperature (EBT) has been suggested as a marker of airway inflammation in asthma. Objectives: The aim of the present study was to investigate EBT in asthmatic subjects compared to healthy controls after an exercise challenge test, and in subjects with exercise-induced bronchoconstriction compared to subjects without, and to compare with body temperatures. Methods: A tot

This paper presents a novel method for the analysis of heart rate variability (HRV) during exercise stress testing enhanced with respiratory information. The instantaneous frequency and power of the low frequency (LF) and high frequency (HF) bands of the HRV are estimated by parametric decomposition of the instantaneous autocorrelation function (ACF) as a sum of damped sinusoids. The instantaneous

Dietary fibre and whole grains are recommended to prevent the development of type 2 diabetes. Low glycaemic index foods that are rich in fibre are recommended to control blood glucose levels. Gastric emptying, together with other factors, regulate the postprandial blood glucose response. A delay in the gastric emptying rate (GER) leads to a lower postprandial blood glucose concentration. However,

This study evaluated the sample sizes necessary to estimate several soil and vegetation characteristics within 10% confidence intervals with 95% probability in three terra firme tropical rainforest sites. Across all three plots, the most spatially heterogeneous variables were measurements of total standing crop root mass, ground surface litter mass, litter fall, root growth and soil respiration wh

Crohn's disease and ulcerative colitis are chronic inflammatory disorders of the gastrointestinal tract, and are collectively referred to as inflammatory bowel disease (IBD). IBD is a major cause of lifetime morbidity, has a severe impact on quality of life of patients (equivalent to that of rheumatoid arthritis, asthma, migraine, or diabetes) and constitutes a substantial economic burden to the h

Septic tanks with subsequent soil treatment systems (STS) are a common treatment technique for domestic wastewater in rural areas. Phosphorus (P) leakage from such systems may pose a risk to water quality (especially if they are located relatively close to surface waters). In this study, six STS in Sweden (11-28 years old) were examined. Samples taken from the unsaturated subsoil beneath the distr
