Severe Acute Pancreatitis: Gut Barrier Failure, Systemic Inflammatory Response, Acute Lung Injury, and the Role of the Mesenteric Lymph.

Severe acute pancreatitis (AP) often leads to distant organ dysfunction with a high morbidity and mortality rate. The most common and earliest organ to fail is the lungs, but the exact pathophysiological mechanisms underlying the disease are still unclear. No successful targeted therapy exists, and treatment is limited to organ supportive care. It is believed that the gut is involved in the develo

Comparing mineral magnetic properties of sediments in two reservoirs in "strongly" and "mildly" eroded regions on the Guizhou Plateau, southwest China: A tool for inferring differences in sediment sources and soil erosion

Shibanqiao Reservoir (0.24 km(2)) and Xiaohe Reservoir (0.28 km(2)) have catchments of 6.00 km(2) and 22.69 km(2), respectively. They essentially represent "strongly eroded" (Shibanqiao) and "mildly eroded" (Xiaohe) regions in Guizhou Plateau, southwestern China. Sediment cores were retrieved from the two reservoirs and soils were also sampled from their catchments. Mineral magnetic measurements w

Motivational internalism and folk intuitions

Motivational internalism postulates a necessary connection between moral judgments and motivation. In arguing for and against internalism, metaethicists traditionally appeal to intuitions about cases, but crucial cases often yield conflicting intuitions. One way to try to make progress, possibly uncovering theoretical bias and revealing whether people have conceptions of moral judgments required f

Multivascular Doppler surveillance in high risk pregnancies

Objectives: Analysis of fetal arterial and venous Doppler predictability for adverse perinatal outcome. Methods: Blood flow in the uterine, umbilical and middle cerbral arteries, umbilical vein, ductus venosus and Galen vein were examined with in 72 h of delivery in 88 high-risk pregnancies. The managing clinicians were only informed about the results of the umbilical artery Doppler. The Doppler r

Genetic polymorphisms confer risk of atrial fibrillation in patients with heart failure: a population-based study.

AIMS: Atrial fibrillation (AF) is a frequent co-morbidity in heart failure (HF) associated with increased mortality, but little is known about the mechanisms underlying AF onset in HF patients. We evaluated the association of cardiovascular and genetic risk factors with AF in HF patients. METHODS AND RESULTS: Individuals hospitalized for HF (n = 1040; 500 with AF) were identified from a large, pop

Exposure to Perfluoroalkyl Substances and Sperm DNA Global Methylation in Arctic and European Populations

Perfluoroalkyl substances (PFASs) are widely used in a variety of industrial processes and products, and have been detected globally in humans and wildlife. PFASs are suspected to interfere with endocrine signaling and to adversely affect human reproductive health. The aim of the present study was to investigate the associations between exposure to PFASs and sperm global methylation levels in a po

BRICHOS Domains Efficiently Delay Fibrillation of Amyloid beta-Peptide

Amyloid diseases such as Alzheimer, Parkinson, and prion diseases are associated with a specific form of protein mis-folding and aggregation into oligomers and fibrils rich in beta-sheet structure. The BRICHOS domain consisting of similar to 100 residues is found in membrane proteins associated with degenerative and proliferative disease, including lung fibrosis (surfactant protein C precursor; pr

Antibiograms and Randomly Amplified Polymorphic DNA-Polymerase Chain Reactions (RAPD-PCR) as Epidemiological Markers of Gonorrhea

The development of antimicrobial resistance of Neisseria gonorrhoeae arising from wide dissemination of resistant clones is a major global health problem. In this study, a total of 235 isolates of N. gonorrhoeae isolated from patients of Bangrak Hospital were tested for their antibiotic susceptibilities to penicillin, norfloxacin, ofloxacin, ciprofloxacin, spectinomycin, and ceftriaxone. Mutation

Differences in lens optical plasticity in two gadoid fishes meeting in the Arctic.

Arctic and boreal/temperate species are likely to be evolutionary adapted to different light regimes. Currently, the boreal/temperate Atlantic cod (Gadus morhua) is coexisting with the native polar cod (Boreogadus saida) in the Arctic waters around Svalbard, Norway. Here, we studied light/dark adaptative optical plasticity of their eye lenses by exposing fish to bright light during the polar night

Self-Report Diary: A Method to Measure Use of Office Lighting

This methodological study was conducted to examine the suitability and reliability of the diary form to measure lighting use in work places. The occupants of 18 single-occupant offices were asked to report in diary form on their lighting-use-related activities and times present in their offices for one workday every two months from June 2009 through May 2010. Electronic measurement of the occupant

Genome-Wide DNA Methylation Analysis in Melanoma Reveals the Importance of CpG Methylation in MITF Regulation.

The microphthalmia-associated transcription factor (MITF) is a key regulator of melanocyte development and a lineage-specific oncogene in melanoma; a highly lethal cancer known for its unpredictable clinical course. MITF is regulated by multiple intracellular signaling pathways although the exact mechanisms that determine MITF expression and activity remain incompletely understood. In this study,

Optimized Three-Body Gravity Assists and Manifold Transfers in End-to-End Lunar Mission Design

We describe a modular optimization framework for GTO-to-moon mission design using the planar circular restricted three-body problem (PCR3BP) model. The three-body resonant gravity assists and invariant manifolds in the planar restricted three-body problem are used as basic building blocks of this mission design. The mission is optimized by appropriately timed delta-Vs, which are obtained by a shoo

Water-Based Exercise for Patients with Chronic Arm Lymphedema: A Randomized Controlled Pilot Trial.

OBJECTIVE: The aim of this study was to evaluate the feasibility and effect of a water-based exercise program on lymphedema status and shoulder range of motion among women with breast cancer-related lymphedema. DESIGN: This was a single-blinded, randomized controlled pilot trial. Twenty-nine eligible breast cancer survivors (median, 10 yrs after surgery) with arm lymphedema (median, 21% interlimb

Propionic and butyric acids, formed in the caecum of rats fed highly fermentable dietary fibre, are reflected in portal and aortic serum.

SCFA are important end products formed during colonic fermentation of dietary fibre (DF). It has been suggested that propionic and butyric acids affect metabolic parameters, low-grade systemic inflammation, insulin resistance and obesity. The aim of the present study was to investigate whether the various SCFA profiles observed after fermentation in the caecum of rats fed pectin, guar gum and fruc

Prognosis of aphasia in stroke patients early after iv thrombolysis.

OBJECTIVE: Stroke patients with aphasia have a high long-term morbidity. Intravenous rt-PA (iv) thrombolysis is given more deliberately to these patients. Early outcome data is lacking. Aim of this study was to determine early benefit from rt-PA in patients with aphasia. METHODS: Data of stroke patients treated by iv thrombolysis was scrutinized for the presence of aphasia defined as ≥1 point
