The present immunohistochemical investigation reveals that difucosylated carbohydrate antigens (DFCA) are extensively expressed in rectal and rectosigmoid carcinomas while normal mucosa and hyperplastic polyps are mainly negative. The adenomas showed intermediate staining patterns where adenomas with villous structures and moderate-severe dysplasia resembled of carcinomas. CEA was more extensively

Let A be a real symmetric n x n-matrix with eigenvalues, lambda(1),..., lambda(n) ordered after decreasing absolute value, and b an n x 1-vector. We present an algorithm finding approximate solutions to min x*(Ax+b) and maxx*(Ax+b) over x is an element of {-1,1}(n), with an absolute error of at most (c(1) vertical bar lambda(1)vertical bar +vertical bar lambda([c2 log n])vertical bar)2n + O(alpha

Glycosphingolipids and sphingomyelin (SM) are important components of the apical brush border and the Golgi and enclocytic vesicles of the gut epithelium. In particular, glucosylceramide is abundant in the microvilli. Synthesis and degradation of mucosal sphingolipids and targeting of sphingolipids to distinct cell compartments during cell differentiation are thus important features of intestinal

OBJECTIVE: To explore a possible temporal association between changes in antidepressant sales and suicide rates in different age groups. METHODS: A time series analysis using a two-slope model to compare suicide rates in Sweden before and after introduction of the selective serotonin reuptake inhibitors, SSRIs. RESULTS: Antidepressant sales increased between 1977-1979 and 1995-1997 in men from 4.2

Numerous lineages of avian malaria parasites of the genus Plasmodium have been deposited in GenBank. However, only seven morphospecies have been linked to these lineages. This study linked two molecular sequences with morphospecies of malaria parasites. Two species of Plasmodium (mitochondrial cytochrome b gene lineages P-GRW2 and P-GRW4) were isolated from naturally infected adult great reed warb

Objective. Although anti-double-stranded DNA (anti-dsDNA) antibodies are important in lupus nephritis, the question regarding which glomerular structures (a-actinin, nucleosomes, or others) are recognized by nephritogenic anti-dsDNA antibodies is still controversial. In this study, we determined which glomerular structures are recognized by monoclonal and in vivo-bound nephritogenic antibodies. Me

A full understanding of the properties of substellar objects is one of the major challenges facing astrophysics. Since their discovery in 1995, hundreds of brown dwarfs and extrasolar planets have been discovered. While these discoveries have enabled important comparisons with theory, observational progress has been much more rapid than the theoretical understanding of cool atmospheres. The reliab

Total plasma homocysteine (tHcy) concentration is elevated in elderly patients with mental illness compared to control subjects. There are many different determinants of plasma tHcy concentration, including the presence of vascular disease. The presence of vascular disease may contribute to cognitive impairment. Clarification of the role of vascular risk factors in mental illness is important beca

Recombinant adeno-associated viral (rAAV) vector-induced neuropeptide Y (NPY) overexpression in the hippocampus exerts powerful antiepileptic and antiepileptogenic effects in rats. Such gene therapy approach could be a valuable alternative for developing new antiepileptic treatment strategies. Future clinical progress, however, requires more detailed evaluation of possible side effects of this tre

In the present work, we show a new approach for decompaction of DNA-cationic surfactant complexes, e.g., lipoplexes, by using beta-cyclodextrin (beta-CD). The DNA decompaction was achieved by dissolving the surfactant aggregates in the complex by making use of the high affinity between the beta-CD and the free surfactant in solution. The results from fluorescence microscopy and adiabatic compressi

Mice with allergically inflamed airways are widely used as animal models of asthma, but their relevance for human asthma is not understood. We, therefore, examined the time course of changes in respiratory input impedance during induced bronchoconstriction in BALB/c mice sensitized and challenged with ovalbumin. Our results indicate that bronchoconstriction in mice is accompanied by complete closu

A 'simulation' theory of cognitive function can be based on three assumptions about brain function. First, behaviour can be simulated by activating motor structures, as during an overt action but suppressing its execution. Second, perception can be simulated by internal activation of sensory cortex, as during normal perception of external stimuli. Third, both overt and covert actions can elicit pe

Ethanol (C2H5OH) adsorption, decomposition and oxidation is studied on Ir(111) using high-energy resolution, fast XPS and temperature-programmed desorption. During heating of an adsorbed ethanol layer a part of the C2H5OHad desorbs molecularly, and another part remains on the surface and decomposes around 200 K; these two decomposition pathways are identified, as via acetyl (H3C-,C=O) and via COad

Introduction. Assessment of male sexual dysfunction has been the focus of substantial scientific effort. Less research has focused on the development of instruments for the measurement of sexual functioning in aging men. Aim. The aims of this study were: (i) to characterize the psychometric properties of a new brief, reliable, and valid measure of male sexual functioning for use in a large populat

During forward flight, a bird's body generates drag that tends to decelerate its speed. By flapping its wings, or by converting potential energy into work if gliding, the bird produces both lift and thrust to balance the pull of gravity and drag. In flight mechanics, a dimensionless number, the body drag coefficient (C-D,C-par), describes the magnitude of the drag caused by the body. The drag coef

Glucagon, secreted by the a-cells of the pancreatic islets, is the most important glucose-increasing hormone of the body. The precise regulation of glucagon release remains incompletely defined but has been proposed to involve release of inhibitory factors from neighbouring P-cells (paracrine control). However, the observation that glucose can regulate glucagon secretion under conditions when insu

The hormonal system for induction of term and preterm labour is not fully understood. Therefore, we investigated myometrial gene expressions for neurohypophyseal hormones and their receptors, prostaglandin F2 and ovarian steroid receptors in women delivered by Caesarean section. Myometrial tissue for real time PCR was collected from 39 women delivered at term before and after the onset of labour a

Photofragmentation laser-induced fluorescence (PF-LIF) is for the first time demonstrated to be a practical diagnostic tool for detection of hydrogen peroxide. Point measurements as well as two-dimensional (2D) measurements in free-flows, with nitrogen as bath gas, are reported. The present application of the PF-LIF technique involves one laser, emitting radiation of 266 nm wavelength, to dissocia
