The main goals of SI are usually to improve learning and student performance as well as increasing retention. The achievement of these goals are evaluated based on linking SI attendance with retention and student results (student performance is here often seen as a proxy for learning). However, the objectives with introducing an SI-program at a higher education institute is often so much more than

BACKGROUND: In mitral valve dysfunction, noninvasive measurement of transmitral blood flow is an important clinical examination. Flow imaging of the mitral valve, however, is challenging, since it moves in and out of the image plane during the cardiac cycle.PURPOSE: To more accurately measure mitral flow, a slice-following MRI phase contrast sequence is proposed. This study aimed to implement such

Objective: Odontoblasts are thought to be involved in innate immunity but their precise role in this process is not fully understood. Here, we assess effects of lipopolysaccharide (LPS) and lipoteichoic acid (LTA), produced by Gram-negative and Gram-positive bacteria, respectively, on matrix metalloproteinase-8 (MMP-8), interleukin-6 (IL-6) and cathelin-related antimicrobial peptide (CRAMP) expres

Background: Pituitary adenylate cyclase-activating polypeptide (PACAP) occurs as either a 27- or 38-amino acid neuropeptide and belongs to the vasoactive intestinal polypeptide/glucagon/secretin family of peptides. PACAP and vasoactive intestinal polypeptide have a 68% homology of their amino acid sequences and share three B-type G-protein coupled receptors: VPAC1, VPAC2 and PAC1 receptors. Method

The effects of mercury added as Hg(2+) and selenium as selenite to cultures of the sulfate reducing bacterium Desulfovibrio desulfuricans were investigated under controlled laboratory conditions. There was no significant difference in the growth curves in comparison to control except in the 0.5 μM Hg-6.3 μM Se combined system in which Hg methylation was significantly reduced. A significant decreas

Mutations within the amyloid-β (Aβ) domain of the amyloid precursor protein (APP) typically generate hemorrhagic strokes and vascular amyloid angiopathy. In contrast, the Arctic mutation (APP E693G) results in Alzheimer's disease. Little is known about the pathologic mechanisms that result from the Arctic mutation, although increased formation of Aβ protofibrils in vitro and intraneuronal Aβ aggre

The aim of this study was to test the usefulness of polyurethane foam (PUF) passive air samplers as stationary, and, for the first time, as personal samplers for one week’s sampling period of polycyclic aromatic hydrocarbons (PAHs) in occupational air. Routine monitoring of workplace exposure is commonly performed with active sampling. However, active samplers can sometimes be unsuitable; e.g., it

Malignant melanoma is among the most aggressive skin cancers and it has among the highest metastatic potentials. Although surgery to remove the primary tumor is the gold standard treatment, once melanoma progresses and metastasizes to the lymph nodes and distal organs, i.e., metastatic melanoma (MM), the usual outcome is decreased survival. To improve survival rates and life span, advanced treatme

Cellulose is the most abundant polymer and a very important renewable resource. Since cellulose cannot be shaped by melting, a major route for its use for novel materials, new chemical compounds and renewable energy must go via the solution state. Investigations during several decades have led to the identification of several solvents of notably different character. The mechanisms of dissolution i

This paper evaluates whether a net-zero energy building (NZEB) can be attained by implementing on-site renewable electricity production when renovating to Passive House level. The assessment is based on the Swedish single-family housing stock constructed between 1961 and 1980, using two case study houses and three locations. Specific conditions of the houses, such as the type of heat generation an

It is important that climate models can accurately simulate the terrestrial carbon cycle in the Arctic due to the large and potentially labile carbon stocks found in permafrost-affected environments, which can lead to a positive climate feedback, along with the possibility of future carbon sinks from northward expansion of vegetation under climate warming. Here we evaluate the simulation of tundra

BACKGROUND: Previous results from Scandinavian cohorts have shown that obesity accentuates the effects of common genetic susceptibility variants on increased triglycerides (TG). Whether such interactions are present in the US population and further selective for particular TG-rich lipoprotein subfractions is unknown. METHODS: We examined these questions using body mass index (BMI) and waist circum

A modelling methodology was developed that simulates the resulting pH and alkalinity in the mixing zone when acidic water is discharged into a river. The input to the model are the: pH, alkalinity, flow, and temperature of both the river water and the acidic discharge. Two different scenarios were simulated: (1) a change of pH in the acidic discharge, assuming constant flow; and (2) a change in th
