A qualitative study on promoting reablement among older people living at home in Norway: opportunities and constraints.

Background: Healthcare services that traditionally have been provided in long-term care institutions in Norway are increasingly being delivered at home to a growing population of older people with chronic conditions and functional limitations. Fostering reablement among older people is therefore important if they are to live safety at home for as long as possible. This study examines how healthcare professionals and managers (staff) in Norwegian municipalities promote reablement among community-dwelling older people.

Comorbidities of Chronic Complete Right Bundle Branch Block and Correlations With Coronary Angiographic Findings.

Background: This is a prospective, observational review of medical records to investigate the associated comorbidities and angiographic anatomy in patients with chronic right bundle branch block (RBBB).

Methods: The analyses of 32,345 consecutive electrocardiograms (EKGs) between October 2010 and January 2012 revealed 583 patients with RBBB. The common comorbidities associated with RBBB were hypertension (82%), diabetes (42%), coronary artery disease (CAD) (44%), valvular heart disease (aortic--16% and mitral--17%) and pulmonary disease (33%).

Left atrial volume by echocardiography in patients with false positive myocardial perfusion scans.

A stress-induced myocardial perfusion abnormality (MPS), in the absence of angiographically significant epicardial coronary artery disease, is considered a "false-positive" test result. We hypothesized that echocardiography would provide complementary prognostic and pathophysiologic data relevant to the management of patients with MPS and normal coronary angiograms. Accordingly, left atrial volume index (LAVi) was assessed by echocardiography in 38 patients with false positive MPS as defined by normal coronary angiograms and 26 patients with true negative MPS from a total of 1,356 patients stressed from July 2006-May 2008.

ST6GalNAc-I controls expression of sialyl-Tn antigen in gastrointestinal tissues.

Sialyl-Tn is a simple mucin-type carbohydrate antigen aberrantly expressed in gastrointestinal adenocarcinomas and in the precursor lesion intestinal metaplasia. Sialyl-Tn tumour expression is an independent indicator of poor prognosis. We have previously shown in vitro that ST6GalNAc-I and ST6GalNAc-II sialyltransferases can synthesize sialyl-Tn.

Seromic profiling of colorectal cancer patients with novel glycopeptide microarray.

Cancer-associated autoantibodies hold promise as sensitive biomarkers for early detection of cancer. Aberrant post-translational variants of proteins are likely to induce autoantibodies, and changes in O-linked glycosylation represent one of the most important cancer-associated post-translational modifications (PTMs). Short aberrant O-glycans on proteins may introduce novel glycopeptide epitopes that can elicit autoantibodies because of lack of tolerance.

Major ion chemistry and hydrochemical studies of groundwater of parts of Palar river basin, Tamil Nadu, India.

Groundwater is almost globally important for human consumption as well as for the support of habitat and for maintaining the quality of base flow to rivers, while its quality assessment is essential to ensure sustainable safe use of the resources for drinking, agricultural, and industrial purposes. In the current study, 50 groundwater samples were collected from parts of Palar river basin to assess water quality and investigate hydrochemical nature by analyzing the major cations (Ca, Mg, Na, K) and anions (HCO(3), Cl, F,SO(4), NO(3), PO(4),CO(3), HCO(3), and F) besides some physical and chemical parameters (pH, electrical conductivity, alkalinity, and total hardness). Also, geographic information system-based groundwater quality mapping in the form of visually communicating contour maps was developed using ArcGIS-9.

Spatial assessment of groundwater quality in Mamundiyar basin, Tamil Nadu, India.

Understanding the groundwater quality is important as it is the main factor determining its suitability for drinking, domestic, agricultural, and industrial purposes. In order to assess the groundwater quality, 30 groundwater samples have been collected in year 2008. The water samples collected in the field were analyzed for electrical conductivity, pH, total dissolved solids (TDS), major cations like calcium, magnesium, sodium, potassium, and anions like bicarbonate, carbonate, chloride, nitrate, and sulfate, in the laboratory using the standard methods given by the American Public Health Association.

Investigation of groundwater quality in hardrock terrain using Geoinformation System.

Two hundred sample sites were selected systematically and samples were taken for a baseline study to understand the geochemistry of the groundwater and to assess the overall physicochemical characteristics. Sampling was carried out using pre-cleaned polyethylene containers. The physical and chemical parameters of the analytical results of groundwater were compared with the standard guideline values recommended by the World Health Organization for drinking and public health standards.

Deciphering groundwater potential zones in hard rock terrain using geospatial technology.

Remote sensing and geographical information system (GIS) has become one of the leading tools in the field of groundwater research, which helps in assessing, monitoring, and conserving groundwater resources. This paper mainly deals with the integrated approach of remote sensing and GIS to delineate groundwater potential zones in hard rock terrain. Digitized vector maps pertaining to chosen parameters, viz.

Fluorine contamination in groundwater: a major challenge.

Fluoride in high concentration in groundwater has been reported from many parts of India. However, a systematic study is required to understand the behavior of fluoride in natural water in terms of local hydrogeological setting, climatic conditions, and agricultural practices. The present study is an attempt to assess hydrogeochemistry of groundwater in parts of Palar river basin pertaining to Kancheepuram district Tamil Nadu to understand the fluoride abundance in groundwater and to deduce the chemical parameters responsible for the dissolution activity of fluoride.

A unique set of SH3-SH3 interactions controls IB1 homodimerization.

Islet-brain 1 (IB1 or JIP-1) is a scaffold protein that interacts with components of the c-Jun N-terminal kinase (JNK) signal-transduction pathway. IB1 is expressed at high levels in neurons and in pancreatic beta-cells, where it controls expression of several insulin-secretory components and secretion. IB1 has been shown to homodimerize, but neither the molecular mechanisms nor the function of dimerization have yet been characterized.

Crystallization and preliminary crystallographic characterization of an SH3 domain from the IB1 scaffold protein.

IB1 is a mammalian scaffold protein that interacts with components of the c-Jun N-terminal kinase (JNK) signal-transduction pathway mainly via its protein-protein interaction domains. Crystallization of the key Src homology 3 (SH3) domain of IB1 has been achieved. Crystallization experiments with unmodified protein and deliberately oxidized protein have led to different crystal forms.

Oligosaccharide and sucrose complexes of amylosucrase. Structural implications for the polymerase activity.

The glucosyltransferase amylosucrase is structurally quite similar to the hydrolase alpha-amylase. How this switch in functionality is achieved is an important and fundamental question. The inactive E328Q amylosucrase variant has been co-crystallized with maltoheptaose, and the structure was determined by x-ray crystallography to 2.
