Effect of active site-inactivated factor VIIa on ischaemia/reperfusion injury in a porcine flap model.

In free flap surgery, restored blood flow following a lengthy ischaemic period may lead to necrosis as a result of ischaemia/reperfusion (IR) injury. This injury comprises both proinflammatory and prothrombotic events, where the tissue factor/factor VIIa complex probably has a key role. Active site-inactivated factor VIIa (FFR-rFVIIa) exerts an antithrombotic effect by binding to tissue factor wit

2,3-butanedione monoxime increases speed of relaxation in single muscle fibres of frog

The effects of 2,3-butanedione monoxime (BDM) on intracellular Ca2+ transient and cross-bridge function were studied in frog single fibres from the anterior tibialis muscle of Rana temporaria (sarcomere length, 2.2 m; temperature, 24 C). The fluorescent dye fluo-3 was used to monitor the intracellular free calcium concentration ([Ca2+i) during isometric contractions. BDM (15 m M) reduced the ampli

Soluble Aggregates in Aqueous Solutions of Polyion-Surfactant Ion Complex Salts and a Nonionic Surfactant.

Water-soluble aggregates based on two polyion-surfactant ion "complex salts", consisting of hexadecyltrimethylammonium (C16TA(+)) and polyacrylate (PA(-)) with either 25 or 6000 repeating units, with added nonionic surfactant octaethylene glycol monododecyl ether (C12E8) have been investigated. A previous phase study has shown that added C12E5 or C12E8 can solubilize complex salts in aqueous syste

Substrate complexation and aggregation influence the cyclodextrin glycosyltransferase (CGTase) catalyzed synthesis of alkyl glycosides.

Bacillus macerans cyclodextrin glycosyltransferase (CGTase) was used to convert dodecyl-β-maltoside (DDM) to dodecyl-β-maltooctaoside (DDMO) using α-cyclodextrin (α-CD) or starch as glycosyl donors. At 300mM α-CD, varied DDM concentration and 60°C, the reaction obeyed Michaelis-Menten kinetics with a K(m) value of 18mM and a V(max) value of 100U/mg enzyme. However, at 25mM α-CD the reaction

CRYRING@ESR: present status and future research

The former storage ring CRYRING has been shipped from the Manne Siegbahn Laboratory in Stockholm to Darmstadt as a Swedish in-kind contribution to FAIR. At its new location downstream of ESR all ion species presently accessible in ESR can be transferred to CRYRING, in which ions with rigidities between 1.44 and 0.054 Tm can be stored. The original Swedish layout has been modified by reconfiguring

Tooth wear in wild boar (Sus scrofa).

In order to study the limitations and possibilities of age estimation based on tooth wear of skeletal remains from wild boar, 315 mandibles from five different populations of wild boar from Poland, Germany and Sweden were analysed. Asymmetric tooth wear between the right and left mandibles was found to be rare and no systematic difference in tooth wear between males and females (less than 36 month

SP which are also known as stimuli-responsive soluble insoluble polymers or environmentally sensitive polymers have been used in the area of biotechnology, medicine and engineering. The present review is

Liposarcoma: a population-based epidemiologic and prognostic study of features of 43 patients, including tumor DNA content

Different conceptions exist regarding the epidemiology and prognosis of liposarcoma, and several classification systems are in use. We analyzed a population-based, 25-year series of 43 patients with liposarcoma of the extremity or trunk wall. Follow-up was complete. The annual incidence was 0.12/10(5). The thigh was the most common location. One of 6 tumors was subcutaneous. Deep-seated tumors wer

Movement of the Intermediate and Rate Determining Transition State of Barnase on the Energy Landscape with Changing Temperature

Barnase folds cooperatively via an intermediate, followed by a rate-limiting transition state. We have probed possible movements of the intermediate and transition state on the energy landscape with changing temperature, from the temperature dependence of -values. These measure interaction energies at the level of individual residues. The results suggest that single destabilizing mutations can red

Pravastatin inhibits pro-inflammatory effects of Alzheimer's peptide Abeta(1-42) in glioma cell culture in vitro.

Statins are known to exert a number of biological effects apart from reducing cholesterol synthesis. The results of recent studies indicate that patients treated with pravastatin have a lower prevalence of diagnosed Alzheimer’s disease (AD). These observations prompted us to examine the effects of pravastatin on Alzheimer’s peptide (Aβ1–42)-induced pro-inflammatory activation in the human glioma c

Distribution of alkaline sphingomyelinase activity in human beings and animals. Tissue and species differences

The alkaline sphingomyelinase (SMase) was first found in rat intestinal brush border. The important roles of this enzyme in digestion of sphingomyelin and in mucosal cell proliferation have been suggested. In the present work, the distribution of the alkaline SMase in the tissues of human beings and animals have been studied. By assaying the enzyme activity in human biopsy samples, we found that t

The influence of external nitrogen on carbon allocation to Glomus intraradices in monoxenic arbuscular mycorrhiza

The influence of external nitrogen (N) on carbon (C) allocation and processes related to phosphorus (P) metabolism were studied in monoxenic arbuscular mycorrhiza (AM) cultures of Daucus carota. Fungal hyphae of Glomus intraradices proliferated from colonized roots growing on solid medium into C-free liquid minimal medium with two different N and P levels. Furthermore, we exposed the colonized roo

The impact of physical training on length of hospital stay and physical function in patients hospitalized with community-acquired pneumonia : protocol for a randomized controlled trial

BACKGROUND: Community-acquired pneumonia (CAP) is a leading cause of hospitalization worldwide. Bed rest with low levels of physical activity is common during periods of hospitalization and leads to functional decline as well as increased risk of complications. The aim of this study is to assess the effect of supervised physical training during hospitalization with CAP compared with standard usual

Increased biventricular hemodynamic forces in precapillary pulmonary hypertension

Precapillary pulmonary hypertension (PHprecap) is a condition with elevated pulmonary vascular pressure and resistance. Patients have a poor prognosis and understanding the underlying pathophysiological mechanisms is crucial to guide and improve treatment. Ventricular hemodynamic forces (HDF) are a potential early marker of cardiac dysfunction, which may improve evaluation of treatment effect. The

Genetic variants in C-type lectin genes are associated with colorectal cancer susceptibility and clinical outcome

Inflammatory responses play a vital role at different stages of colorectal carcinogenesis. C-type lectins mediate inflammatory/immune responses and participate in immune escape of pathogens and tumors. Our study aimed to evaluate the correlation between polymorphisms in three C-type lectin genes, CD209, MBL2 and REG4, and colorectal cancer (CRC) risk and clinical outcome. We genotyped 15 potential

Feedback in Small Systems -A Stochastic Thermodynamic Perspective

Recent advances in nanotechnology and the accompanying development oftechniques that operate and manipulate systems on the micro- and nanometer scale have driven the development of stochastic thermodynamics. This isa theory that can describe small systems far from equilibrium, where the fluctuations are of the same order of magnitude as the mean values. Stochasticthermodynamics can be used to prov
