Pharmacological characterization and expression of VIP and PACAP receptors in isolated cranial arteries of the rat

Vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase activating peptide (PACAP) are potent vasodilators in animals and humans. PACAP infusion but not VIP infusion precipitates migraine attacks in migraine patients. The vascular effects of VIP and the two varieties of PACAP (PACAP-27 and PACAP-38) were investigated versus selective antagonists in segments of rat middle cerebral arter

Measures of birth size in relation to risk of prostate cancer: the Malmo Diet and Cancer Study, Sweden

There is some evidence that perinatal factors, specifically birth weight (BW), may be related to the onset of prostate cancer (PRCA). This case-control study, nested within the Malmo Diet and Cancer Cohort Study, used archived birth record data from 308 incident PRCA cases diagnosed between 1991 and 2005, and 637 age-matched controls among 4781 men born (1923-1945) in Malmo and Lund, Sweden. We ap

Occupations that People with Late Effects of Polio Perceive Difficult to Perform

The aims of this study were to describe which occupations that people with late effects of polio perceive difficult to perform, which occupational area the occupations were related to and their level of complexity. The aims were also to describe their own perception of the importance, performance and satisfaction with these occupations. Sixty-two participants (mean age 61years) were assessed with

Socioeconomic disparities in stroke case fatality - Observations from Riks-Stroke, the Swedish stroke register

Background Low socioeconomic status (low education and income level) has been found to be associated with increased stroke mortality. However, findings from previous studies on the association between socioeconomic status and case fatality (survival) after stroke have been inconsistent. Aims The study aims to explore the association between socio-economic status and survival after stroke using Rik

Rapid shifts in Atta cephalotes fungus-garden enzyme activity after a change in fungal substrate (Attini, Formicidae)

Fungus gardens of the basidiomycete Leucocoprinus gongylophorus sustain large colonies of leaf-cutting ants by degrading the plant material collected by the ants. Recent studies have shown that enzyme activity in these gardens is primarily targeted toward starch, proteins and the pectin matrix associated with cell walls, rather than toward structural cell wall components such as cellulose and hemi

Vertical lidar sounding of atomic mercury and nitric oxide in a major Chinese city

Vertical range-resolved measurements of atmospheric pollutants were performed in a major city in southern China, employing a lidar system operating with an optical parametric oscillator transmitter. Recordings of atomic mercury (Hg) and nitric oxide (NO) absorbing in the deep-UV region were taken, yielding concentration profiles only attainable with lidar techniques. In particular, the potential i

Quantification of Osmotic Water Transport in vivo using Fluorescent Albumin.

Osmotic water transport across the peritoneal membrane is applied during peritoneal dialysis to remove the excess of water accumulated in patients with end-stage renal disease. The discovery of aquaporin water channels and the generation of transgenic animals have stressed the need for novel and accurate methods to unravel molecular mechanisms of water permeability in vivo. Here we describe the us

Sensor Array Composed of "Clicked" Individual Microcantilever Chips

A simple technique is described to functionalize a small library of microcantilever (MC) chips presenting varied headgroups. A generic azide monolayer, bound to the MC surface, can be coupled with various alkynes using efficient "click" chemistry. This method is compatible with many functional groups, and novel headgroups are introduced on the MC surface by means of alkynes synthesized via a one-s

A Review of the Combination of Experimental Measurements and Fibril-Reinforced Modeling for Investigation of Articular Cartilage and Chondrocyte Response to Loading

The function of articular cartilage depends on its structure and composition, sensitively impaired in disease (e. g. osteoarthritis, OA). Responses of chondrocytes to tissue loading are modulated by the structure. Altered cell responses as an effect of OA may regulate cartilage mechanotransduction and cell biosynthesis. To be able to evaluate cell responses and factors affecting the onset and prog

Model- based estimation of optimal temperature profile during simultaneous saccharification and fermentation of Arundo donax.

A kinetic model fitted to enzymatic hydrolysis of Arundo donax was coupled to a fermentation kinetic model derived from simultaneous saccharification and fermentation (SSF) experiments at different temperatures for the determination of optimal temperature profile (between 36-45 (°) C) using iterative dynamic programming (IDP). A sensitivity analysis of enzyme kinetic model not only facilitated mod

Characterization of different FAD-dependent glucose dehydrogenases for possible use in glucose-based biosensors and biofuel cells.

In this study, different flavin adenine dinucleotide (FAD)-dependent glucose dehydrogenases (FADGDHs) were characterized electrochemically after "wiring" them with an osmium redox polymer [Os(4,4'-dimethyl-2,2'-bipyridine)(2)(PVI)(10)Cl](+) on graphite electrodes. One tested FADGDH was that recently discovered in Glomerella cingulata (GcGDH), another was the recombinant form expressed in Pichia pa

Rim Sign in Breast Lesions on Diffusion-Weighted Magnetic Resonance Imaging: Diagnostic Accuracy and Clinical Usefulness

PurposeTo investigate the diagnostic accuracy and clinical usefulness of the rim sign in breast lesions observed in diffusion-weighted magnetic resonance imaging (DWI). Materials and MethodsThe magnetic resonance imaging (MRI) findings of 98 pathologically confirmed lesions (62 malignant and 36 benign) in 84 patients were included. Five breast radiologists were asked to independently review the br

Self-Organization of Motor-Propelled Cytoskeletal Filaments at Topographically Defined Borders

Self-organization phenomena are of critical importance in living organisms and of great interest to exploit in nanotechnology. Here we describe in vitro self-organization of molecular motor-propelled actin filaments, manifested as a tendency of the filaments to accumulate in high density close to topographically defined edges on nano- and microstructured surfaces. We hypothesized that this "edge-t

Implications of the Inability of Listeria monocytogenes EGD-e To Grow Anaerobically Due to a Deletion in the Class III NrdD Ribonucleotide Reductase for Its Use as a Model Laboratory Strain

Listeria monocytogenes is a Gram-positive facultative intracellular bacterium that causes life-threatening diseases in humans. It grows and survives in environments of low oxygen tension and under conditions of strict anaerobiosis. Oxygen-limiting conditions may be an important factor in determining its pathogenicity. L. monocytogenes serovar 1/2a strain EGD-e has been employed intensively to eluc

Subjective outcomes after treatment for velopharyngeal dysfunction.

Abstract Background: Velopharyngeal dysfunction (VPD) can have various causes and may be a significant disability for the affected patient. Treatment options include surgery and speech therapy, but the success rates are often inconsistent. Methods: In this study, self-assessment questionnaires were sent out to 222 Swedish patients with VPD. The questionnaire included questions about satisfaction w
