Cluster N activity under changed light and magnetic field conditions during the night in Sylvia warblers.

Cluster N is a cluster of forebrain regions found in night-migratory songbirds that shows high activation of activity-dependent gene expression during night-time vision. We have suggested that Cluster N may function as a specialized night-vision area in night-migratory birds and that it may be involved in processing light-mediated magnetic compass information. Here, we investigated these ideas. We

On the effect of lactic acid on blood glucose and insulin responses to cereal products: Mechanistic studies in healthy subjects and in vitro

It has been observed that bread containing lactic acid produced during the sourdough fermentation or added directly, has the ability to lower the postprandial glucose and insulin responses in humans. The main objective of the present work was to evaluate the possible mechanisms for a lowered glucose response to bread containing lactic acid, and to determine whether the same phenomenon also occurs

On the charge regulation of proteins

It is known that the overall charge of a protein can change as the molecule approaches a charged object like another protein or a cell membrane. We have formalized this mechanism using a statistical mechanical framework and show how this rather overlooked interaction increases the attraction between protein molecules. From the theory, we can identify a unique property, the protein charge capacitan

Bacteriophage lambda stabilization by auxiliary protein gpD: Timing, location, and mechanism of attachment determined by cryo-EM

We report the cryo-EM structure of bacteriophage lambda and the mechanism for stabilizing the 20-angstrom-thick capsid containing the dsDNA genome. The crystal structure of the HK97 bacteriophage capsid fits most of the T = 7 lambda particle density with only minor adjustment. A prominent surface feature at the 3-fold axes corresponds to the cementing protein gpD, which is necessary for stabilizat

Antiproliferative heparan sulfate inhibiting hyaluronan and transforming growth factor-β expression in human lung fibroblast cells

The objective of this study was to examine the effects of heparan sulfate (HS) on factors involved in the remodeling of connective tissue observed in patients with fibrotic respiratory disorders such as asthma. A suitable working model is to stimulate human fetal lung fibroblasts in vitro with structurally different forms of HS. Highly sulfated and iduronic acid (IdoUA)-rich HS specifically decrea

Cytogenetic Analysis of 101 Giant Cell Tumors of Bone: Nonrandom Patterns of Telomeric Associations and Other Structural Aberrations

Giant cell tumor of bone (GCTB) is a benign but locally aggressive tumor with metastatic potential. We performed cytogenetic analysis on 10 1 GCTB from 92 patients. Karyotypes were obtained from 95 tumors, 47 of which had clonal aberrations. The majority of the cytogenetically abnormal GCTB had multiple, up to 28 per tumor, clones. Clonal telomeric associations (tas) and other structural and numer

Radiologic evaluation of the dysphagic patient

Radiologic evaluation of patients with dysphagia relies on a meticulous and standardized technique. For assessment of function video recording is mandatory. A systematic approach for the description of function and dysfunction is necessary. The following describes such an approach focused on an easy and reproducible technique and a comprehensive description of radiologic events and morphology.

Differential expression of Dystroglycan-spliceforms with and without the mucin-like domain during Drosophila embryogenesis

Dystroglycan (DG) is a widely expressed extracellular matrix (ECM) receptor required for muscle viability, synaptogenesis, basement-membrane formation and epithelial development. As an integral component of the Dystrophin-associated glycoprotein complex, DG plays a central role in linking the ECM and the cytoskeleton. Disruption of this linkage in skeletal muscle is the underlying cause in various

Working memory training decreases hippocampal neurogenesis.

The relationship between adult hippocampal neurogenesis and cognition appears more complex than suggested by early reports. We aimed to determine if the duration and task demands of spatial memory training differentially affect hippocampal neurogenesis. Adult male rats were trained in the Morris water maze in a reference memory task for 4 days, or alternatively working memory for either 4 or 14 da

2.0 Ga granite of the lower package of the Higher Himalayan Crystallines, Maglad Khad, Sutlej valley, Himachal Pradesh

Along the Sutlej valley, the lower package of the Higher Himalayan Crystallines (HHC) exposes a small concordant to discordant intrusive grey granite-The Maglad Khad Granite, within garnet mica schist/banded gneiss of the Jeori Formation. This body is fine grained and foliated along the margins, whereas the central part is relatively undeformed. This body along with aplites and pegmatites intrudes

Identification and characterization of asporin. a novel member of the leucine-rich repeat protein family closely related to decorin and biglycan

Asporin, a novel member of the leucine-rich repeat family of proteins, was partially purified from human articular cartilage and meniscus. Cloning of human and mouse asporin cDNAs revealed that the protein is closely related to decorin and biglycan. It contains a putative propeptide, 4 amino-terminal cysteines, 10 leucine-rich repeats, and 2 C-terminal cysteines. In contrast to decorin and biglyca

White Monte Carlo for time-resolved photon migration.

A novel scheme for fully scalable White Monte Carlo (WMC) has been developed and is used as a forward solver in the evaluation of experimental time-resolved spectroscopy. Previously reported scaling problems are avoided by storing detection events individually, turning spatial and temporal binning into post-simulation activities. The approach is suitable for modeling of both interstitial and nonin

Adipose triglyceride lipase and hormone-sensitive lipase are the major enzymes in adipose tissue triacylglycerol catabolism

The mobilization of free fatty acids from adipose triacylglycerol (TG) stores requires the activities of triacylglycerol lipases. In this study, we demonstrate that adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL) are the major enzymes contributing to TG breakdown in in vitro assays and in organ cultures of murine white adipose tissue (WAT). To differentiate between ATGL- and

Aspects on reliability calibration of safety factors for timber structures

Analyses and a discussion of the consequences for lightweight structures, typical wood frame or truss structures, when a change of the statistical description of random parameters in a reliability based code format is made without considering how the code once was derived is presented. The special case when the statistical description of variable load is altered, is described with and without cons
