Concise Review: Hematopoietic Stem Cell Aging and the Prospects for Rejuvenation.

Because of the continuous increases in lifetime expectancy, the incidence of age-related diseases will, unless counteracted, represent an increasing problem at both the individual and socioeconomic levels. Studies on the processes of blood cell formation have revealed several shortcomings as a consequence of chronological age. They include a reduced ability to mount adaptive immune responses and a

International Organization of Physical Therapy in Mental Health consensus on physical activity within multidisciplinary rehabilitation programmes for minimising cardio-metabolic risk in patients with schizophrenia

Purpose: The excess cardiovascular morbidity associated with schizophrenia is attributed to an interplay between behavioural (physical inactivity, unhealthy diet, substance abuse), genetic and illness related factors, as well as the effects of antipsychotic treatment. Patients have limited access to physical healthcare with less opportunity for cardiovascular risk prevention and treatment programm

Germ tube formation changes surface hydrophobicity of Candida cells

Hydrophobic interaction is generally considered to play an important role in the adherence of microorganisms to eukaryotic cells and also to certain inert surfaces. Using a microbe adhesion assay to hydrocarbons (n-hexadecane), 68 strains of Candida albicans and 30 non-albicans strains were studied. Influence of source of isolate, age of the culture, and percentage of germ tube formation on adhesi

Memory Behavior of the Planar Hall Effect in Ferromagnetic (Ga, Mn)As/GaAs Superlattices

The planar Hall effect (PHE) has been studied in short period (Ga, Mn)As/GaAs superlattices displaying a ferromagnetic interlayer coupling between the magnetic layers. Complex dependence of the PHE on applied magnetic field is explained by taking into account the magnetocrystalline anisotropy of the (Ga, Mn)As layers, which results from biaxial compressive strain in the layers epitaxially grown on

Comparison of echocardiographic and cardiac magnetic resonance imaging for assessing right ventricular function in adults with repaired tetralogy of fallot

Adults with repaired tetralogy of Fallot and significant chronic pulmonary regurgitation are at risk for progressive right ventricular (RV) dilatation and dysfunction. The assessment of RV function is important in the management in these patients. There is still a lack of an adequate geometric model to quantify RV function by echocardiography. The myocardial performance index (MPI) is a nonvolumet

Vanishing magnetic interactions in ferromagnetic thin films

We have used element-specific hysteresis measurements, based on the x-ray magnetic circular dichroism technique, to investigate magnetic trilayer structures composed of Fe and Ni layers. Within a critical regime we have discovered a class of structures in which the exchange interaction, the mechanism responsible for the macroscopic magnetism, can become vanishingly small. The experimental observat

Efficacy and safety of oral alitretinoin (9-cis retinoic acid) in patients with severe chronic hand eczema refractory to topical corticosteroids: results of a randomized, double-blind, placebo-controlled, multicentre trial

Background Patients with severe chronic hand eczema (CHE) refractory to topical corticosteroids currently have limited treatment options suited for chronic use, and few controlled clinical studies have investigated new therapies in this setting. Objectives To assess the efficacy and safety of oral alitretinoin (9-cis retinoic acid) taken at 10 mg or 30 mg once daily for up to 24 weeks, compared wi

Density-dependent reproductive output in relation to a drastically varying food supply: getting the density measure right

When a limiting resource (e.g. food) varies drastically between years, and population density is measured in the conventional way as individuals per area, demographic processes such as productivity and survival may erroneously be considered density-independent. We tested the hypothesis that if the variation in a limiting resource is not taken into account in the density measure, this may lead to e

Drosophila RhoGEF2 associates with microtubule plus ends in an EB1-dependent manner

Members of the Rho/Rac/Cdc42 superfamily of GTPases [1,2] and their upstream activators, guanine nucleotide exchange factors (GEFs) [3], have emerged as key regulators of actin and microtubule dynamics. In their GTP bound form, these proteins interact with downstream effector molecules that alter actin and microtubule behavior. During Drosophila embryogenesis, a Galpha subunit (Concertina) and a R

Review of Cognitive Behavioral Therapy with Children: A Guide for the Community Practitioner

Cognitive behavioral therapy with children: A guide for the community practitioner by K. Manassis (see record 2009-01291-000). This book is a clearly written and concise guide for therapists who may have had some exposure to a manualized CBT program for children, but have had little formal training or supervision in CBT. While there is a heavy focus on anxiety and depression, the book is really ab

Identification of protein tyrosine phosphatases associating with the PDGF receptor

Protein tyrosine phosphatase (PTP) in-gel assays were used to explore association of PTPs with the platelet-derived growth factor beta-receptor (PDGFbetaR). Five PTP activity bands of approximately 120, approximately 70, approximately 60, approximately 53, and approximately 45 kDa could be detected in PDGFbetaR immunoprecipitates and were identified by immunodepletion experiments as PTP-PEST, SHP-

Sex-specific developmental plasticity in response to yolk corticosterone in an oviparous lizard

Corticosterone exposure during prenatal development as a result of maternal upregulation of circulating hormone levels has been shown to have effects on offspring development in mammals. Corticosterone has also been documented in egg yolk in oviparous vertebrates, but the extent to which this influences phenotypic development is less studied. We show that maternal corticosterone is transferred to

Interactions between gemini surfactants, 12-s-12, and beta-cyclodextrin as investigated by NMR diffusometry and electric conductometry

The interaction between beta-cyclodextrin (CD) and gemini surfactant of the type alkyl-alpha,omega-bis(dodecyldimethyl-ammonium bromide) with different spacer lengths of 2, 8, and 10 carbons has been investigated by means of electric conductivity (EC) and proton self-diffusion NMR at 298 K. The formation of a 2: 1 (CD: gemini) complex in a two-step mechanism is observed with the first association

Energy and Mass Exchange and the Productivity of Main Siberian Ecosystems (from Eddy Covariance Measurements). 1. Heat Balance Structure over the Vegetation Season

Direct measurements of heat balance (latent heat and sensible heat fluxes) by the eddy covariance method, undertaken in 1998-2000 and 2002-2004, are used to obtain information on the daily, seasonal, and annual dynamics of energy and mass exchange between the atmosphere and the typical ecosystems of Siberia (middle taiga pine forest, raised bog, and true four grass steppe with data for typical tun

Polyelectrolytes confined to spherical cavities

The effects of confining a polyelectrolyte solution containing a polyion and its counterions in spherical cavities of different sizes have been investigated by Monte Carlo simulations using a simple model system. Polyions of three different linear charge densities and counterions of three different valences have been examined. Structure, energy, and free energy properties of all systems have been

The long-term course of depressive disorders in the Lundby Study.

Background. The Lundby Study is a longitudinal cohort study on a geographically defined population consisting of 3563 subjects. Information about episodes of different disorders was collected during field investigations in 1947, 1957, 1972 and in 1997. Interviews were carried out about current health and past episodes since the last investigation; for all subjects information was also collected fr

Dietary fibre in food and protection against colorectal cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC): an observational study

Background Dietary fibre is thought to protect against colorectal cancer but this view has been challenged by recent prospective and intervention studies that showed no protective effect. Methods We prospectively examined the association between dietary fibre intake and incidence of colorectal cancer in 519 978 individuals aged 25-70 years taking part in the EPIC study, recruited from ten European

A Novel Approach of Retrofitting a Combined Cycle With Post Combustion CO2 Capture

Most state-of-the-art natural gas-fired combined cycle (NGCC) plants are triple-pressure reheat cycles with efficiencies close to 60%. However, with carbon capture and storage, the efficiency will be penalized by almost 10% units. To limit the energy consumption for a carbon capture NGCC plant, exhaust gas recirculation (EGR) is necessary. Utilizing EGR increases the CO2 content in the gas turbine

Palaeoclimate perturbations before the Sheinwoodian glaciation: A trigger for extinctiond during the 'Ireviken Event'

Telychian to Sheinwoodian conodonts (Pterospathodus eopennatus ssp. n. 1 Zone through the Ozarkodina sagitta rhenana Superzone) were studied in detail for their oxygen isotope composition. The Upper Kockelella ranuliformis and Ozarkodina sagitta rhenana Zones represent the peak interval of the Sheinwoodian positive δ18Oapatite excursion reflecting the coolest conditions with marine sea–water tempe

Common variants in LSP1, 2q35 and 8q24 and breast cancer risk for BRCA1 and BRCA2 mutation carriers

Genome-wide association studies of breast cancer have identified multiple single nucleotide polymorphisms (SNPs) that are associated with increased breast cancer risks in the general population. In a previous study, we demonstrated that the minor alleles at three of these SNPs, in FGFR2, TNRC9 and MAP3K1, also confer increased risks of breast cancer for BRCA1 or BRCA2 mutation carriers. Three addi
