BACKGROUND: Oxygen free radicals (OFRs), platelet activating factor (PAF), cell adhesion molecules, and transmigration of polymorphonuclear leukocytes through the gut barrier are probably all essential in the development of gut barrier dysfunction following intestinal ischemia and reperfusion (I/R). Pretreatment and early treatment of I/R with the OFRs-scavenger (NAC), the PAF inhibitor lexipafant

The time tau(n) of first passage from queue length x to queue lengthn > x in a many-server queue with both the arrival process and service intensities governed by a finite Markov process is considered. The mean and the Laplace transform are computed as solutions of systems of linear equations coming out by optional stopping of a martingale obtained as a stochastic integral of the exponential Wald

It has been suggested that bone mineral density (BMD) measurements should be made at multiple sites, and that the lowest T-score should be taken for the purpose of diagnosing osteoporosis. The aim of this study was to examine the use of BMD measurements at the femoral neck and lumbar spine alone and in combination for fracture prediction. We studied 19,071 individuals (68% women) from six prospect

The glandular kallikrein family is composed of structurally related serine proteases. Studies show that the mouse family encompasses at least 14 highly conserved functional genes, but of these only the tissue kallikarein has a human ortholog. In man, the tissue kallikrein display high sequence similarity with prostate specific antigen and human glandular kallikrein 2, suggesting that they evolved

Smooth muscle is a slow and economical muscle with a large variability in contractile properties. This review describes results regarding the relation between expression of myosin isoforms and the contraction of smooth muscle. The focus of the review is on studies of the organised contractile system in the smooth muscle tissue. The role of the myosin heavy chain variants formed by alternative spli

Experimental studies have revealed that both downstream and upstream pointing V-shaped ribs result in more heat transfer enhancement than transverse straight ribs in ducts. However, based on the available experimental results, contradiction exists whether the upstream or the downstream pointing V-shaped ribs orientation is superior for better enhancement in heat transfer. Further investigations ar

Objective. Pancreatic pseudocyst is a common complication of both acute and chronic pancreatitis. The aim of the present study was to evaluate the efficacy and complications of different treatment regimens. Material and methods. All patients >= 15 years of age admitted to Lund University Hospital from 1994 to 2003 with pancreatic pseudocysts were analysed retrospectively. Pseudocysts were defined

We describe a laboratory exercise that is designed to give advanced undergraduate students in analytical chemistry a meaningful introduction to biological mass spectrometry. We ask the students to solve a mystery: given two proteins, what are they, and from which animals do they originate? This exercise involves use of two mass spectrometers available in our institution: a fairly basic matrix-assi

Objective. To compare leisure activities and associated factors in a group with recent onset RA and matched community-derived controls, to examine whether leisure activities are altered during the early years of disease and to seek predictors. Methods. One hundred and forty-seven consecutive persons with early RA were followed for 0.9-5.9 yr. One hundred and forty-four RA patients were compared cr

Specific antiarrhythmic therapy with class I and III drugs for atrial fibrillation (AF) conversion and prevention of its recurrence is frequently utilized in clinical practice. Besides being only moderate effective, the utilization of antiarrhythmic drugs may be associated with serious side effects. In the clinical setting it is difficult to directly evaluate the effects of antiarrhythmic drugs on

Ca(v)1.2 and Ca(v)1.3 L-type Ca2+ channels (LTCCs) are believed to underlie Ca2+ currents in brain, pancreatic beta cells, and the cardiovascular system. In the CNS, neuronal LTCCs control excitation-transcription coupling and neuronal plasticity. However, the pharmacotherapeutic implications of CNS LTCC modulation are difficult to study because LTCC modulators cause card iovascular (activators an

This brief overview summarizes some recent developments from our Center for Molecular Imprinting related to the topic of this symposium. After a short presentation of the principle of molecular imprinting and recognition, the use of different materials including hybrids for the formation of the host will be discussed, followed by examples given of different formats used such as small polymer beads

In this work, simple microcontact printed gold-wafers were used to make a lectin panel for investigation and discrimination of different meat juices from fresh meat of cattle, chicken, pig, cod, turkey and lamb. Seven different lectins were thus attached to gold surfaces using the streptavidin–biotin method. Lectins recognize and bind specifically to carbohydrate structures present on different pr
