Social capital and change in psychological health over time.

The positive association between social capital and general health outcomes has been extensively researched over the past decade; however, studies investigating social capital and psychological health show less consistent results. Despite this, policy-makers worldwide still employ elements of social capital to promote and improve psychological health. This United Kingdom study investigates the ass

Enhanced Activity of Transforming Growth Factor beta 1 (TGF-beta 1) Bound to Cartilage Oligomeric Matrix Protein

Cartilage oligomeric matrix protein (COMP) is an important non-collagenous cartilage protein that is essential for the structural integrity of the cartilage extracellular matrix. The repeated modular structure of COMP allows it to "bridge" and assemble multiple cartilage extracellular matrix components such as collagens, matrilins, and proteoglycans. With its modular structure, COMP also has the p

Glutamate dehydrogenase, insulin secretion and Type 2 Diabetes. A new means to protect the pancreatic β-cell?

In this issue of Journal of Endocrinology, Dr Han and colleagues report a protective effect of the glutamate dehydrogenase-activator BCH under diabetes-like conditions that impair β-cell function in both a pancreatic β-cell line and in db/db mice. Based on these observations, the authors suggest that BCH could serve as novel treatment modality in Type 2 Diabetes. The present commentary discusses t

How scientists may ‘benefit from the mess’: A resource dependence perspective on individual organizing in contemporary science

There is general consensus in the study of science, and especially research policy studies, that a wave of profound change has struck academic science in the past decades. Central parts of this change are increased competition, growing demands of relevance and excellence, and managerialism reforms in institutions and policy systems. The underpinning thesis of this article is that, if seen from the

On max-min fair flow optimization in wireless mesh networks

The paper is devoted to modeling wireless mesh networks (WMN) through mixed-integer programming (MIP) formulations that allow to precisely characterize the link data rate capacity and transmission scheduling using the notion of time slots. Such MIP models are formulated for several cases of the modulation and coding schemes (MCS) assignment. We present a general way of solving the max–min fairness

Left ventricular AV-plane displacement is preserved with lifelong endurance training and is the main determinant of maximal cardiac output.

Age-related decline in cardiac function can be prevented or postponed by lifelong endurance training. However, effects of normal ageing as well as of lifelong endurance exercise on longitudinal and radial contribution to stroke volume are unknown. The aim of this study was to determine resting longitudinal and radial pumping in elderly athletes, sedentary elderly and young sedentary subjects. Furt

From circulating biomarkers to genomics and imaging in the prediction of cardiovascular events in the general population.

Abstract Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. In the last decades numerous markers have been considered and investigated for the prediction of CV events, but only a few of them resulted in improved global risk assessment beyond traditional risk factors when incorporated into coronary evaluation scores. Recent genetic studies have pointed out a few bu

Concerns About Falling in Parkinson's Disease: Associations with Disabilities and Personal and Environmental Factors.

Fear of falling can be conceptualized in different ways, e.g., as concerns about falling or low fall-related self-efficacy. It is common in people with Parkinson's disease (PD), and there is growing knowledge about its contributing factors. However, previous multivariate studies have mainly focused on fear of falling in relation to PD-related disabilities, and less is known about the associations

Reduced content of chloroatranol and atranol in oak moss absolute significantly reduces the elicitation potential of this fragrance material

BackgroundOak moss absolute, an extract from the lichen Evernia prunastri, is a valued perfume ingredient but contains extreme allergens. ObjectivesTo compare the elicitation properties of two preparations of oak moss absolute: classic oak moss', the historically used preparation, and new oak moss', with reduced contents of the major allergens atranol and chloroatranol. Patients/materials/methodsT

FIB Plan and Side View Cross-Sectional TEM Sample Preparation of Nanostructures.

Focused ion beam is a powerful method for cross-sectional transmission electron microscope sample preparation due to being site specific and not limited to certain materials. It has, however, been difficult to apply to many nanostructured materials as they are prone to damage due to extending from the surface. Here we show methods for focused ion beam sample preparation for transmission electron m

Expression of functional toll like receptor 4 in estrogen receptor/progesterone receptor-negative breast cancer.

Toll-like receptors (TLRs) are a family of pattern recognition receptors that are expressed on cells of the innate immune system. The ligands can be pathogen derived (pathogen associated molecular patterns; PAMPs) or endogenous (damage associated molecular patters; DAMPs) that when bound induces activation of nuclear factor kappa B (NF-κB) and transcription of pro-inflammatory genes. TLRs have als

Measurement of the parity-violating asymmetry parameter ab and the helicity amplitudes for the decay Lambda(0)(b) -> J/psi Lambda(0) with the ATLAS detector

A measurement of the parity-violating decay asymmetry parameter, ab, and the helicity amplitudes for the decay.Lambda(0)(b) -> J/psi(mu(+) mu(-)) Lambda(0)(p pi(-)) is reported. The analysis is based on 1400 Lambda(0)(b)and (Lambda) over bar (0)(b) baryons selected in 4.6 fb(-1) of proton-proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. By co

In vitro TRPV1 activity of piperine derived amides

A series of natural and synthetic piperine amides were evaluated for activity on the human TRPV1 expressed in HEK293 cells. The agonistic effect of piperine amides was mainly dependent on the length of the carbon chain. Structural changes of double bonds and stereochemistry in the aliphatic chain of these compounds did not change their potency or efficacy, indicating that increased rigidity or pla

Common breast cancer susceptibility alleles are associated with tumour subtypes in BRCA1 and BRCA2 mutation carriers: results from the Consortium of Investigators of Modifiers of BRCA1/2

Introduction: Previous studies have demonstrated that common breast cancer susceptibility alleles are differentially associated with breast cancer risk for BRCA1 and/or BRCA2 mutation carriers. It is currently unknown how these alleles are associated with different breast cancer subtypes in BRCA1 and BRCA2 mutation carriers defined by estrogen (ER) or progesterone receptor (PR) status of the tumou

Improved quantification of small hearts for gated myocardial perfusion imaging

In patients with a small heart, defined as an end-systolic volume (ESV) of a parts per thousand currency sign20 mL calculated using the Quantitative Gated SPECT (QGS) program, underestimation of ESV and overestimation of ejection fraction (EF) using gated myocardial perfusion imaging are considered errors caused by inappropriate delineation of the left ventricle (LV). The aim of this study was to

Mapping of quick clay using geoelectrical imaging and CPTU-resistivity

Quick clay has a major impact on landslide risk and it is therefore of considerable interest to map its presence and extent. In Sweden, quick clay has been involved in most landslides in soft clay with serious consequences. The predominant method for detection of quick clay in Sweden has been to take undisturbed samples and to perform fall-cone tests on the clay in its undisturbed and remoulded st

MicroRNA-135b regulates ERα, AR and HIF1AN and affects breast and prostate cancer cell growth.

MicroRNAs (miRNAs) regulate a wide range of cellular signaling pathways and biological processes in both physiological and pathological states such as cancer. We have previously identified miR-135b as a direct regulator of androgen receptor (AR) protein level in prostate cancer (PCa). We wanted to further explore the relationship of miR-135b to hormonal receptors, particularly estrogen receptor α

Light-dependent magnetic compass orientation in amphibians and insects: candidate receptors and candidate molecular mechanisms

Magnetic compass orientation by amphibians, and some insects, is mediated by a light-dependent magnetoreception mechanism. Cryptochrome photopigments, best known for their role in circadian rhythms, are proposed to mediate such responses. In this paper, we explore light-dependent properties of magnetic sensing at three levels: (i) behavioural (wavelength-dependent effects of light on magnetic comp

Desulfation followed by sulfation: Metabolism of benzylglucosinolate in Athalia rosae (Hymenoptera: Tenthredinidae)

The sawfly species Athalia rosae (L.) (Hymenoptera: Tenthredinidae) is phytophagous on plants of the family Brassicaceae and thus needs to cope with the plant defence, the glucosinolate-myrosinase system. The larvae sequester glucosinolates in their haemolymph. We investigated how these compounds are metabolized by this specialist. When larvae were fed with ([ 14C]-labelled) benzylglucosinolate, o
