Results are presented from data recorded in 2009 by the PHENIX experiment at the Relativistic Heavy Ion Collider for the double-longitudinal spin asymmetry, A(LL), for pi(0) and eta production in root s = 200 GeV polarized p + p collisions. Comparison of the pi(0) results with different theory expectations based on fits of other published data showed a preference for small positive values of gluon

PURPOSE: Cadmium in urine is positively associated with urinary 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) concentrations, a sensitive marker of oxidative DNA damage. We determined whether kidney concentrations of cadmium, mercury, and lead, which may generate oxidative DNA damage, were associated with urinary 8-oxodG or not. METHODS: 8-OxodG was measured in separate 24 h and overnight urine sa

Although treaty interpretation is undoubtedly an activity governed by international law, and by Articles 31-33 of the 1969 Vienna Convention on the Law of Treaties (VCLT) in particular, some commentators continue repeating the pre-Vienna adage that treaty interpretation is a matter of art and not science, the implication of which is that no understanding of a treaty provision can ever be explained

The purpose of this article is to compare within-family successions and external-party takeovers in family-owned manufacturing SMEs to determine potential differences in how they are perceived and managed. This paper focuses on two long-term aspects of family businesses – their succession and their ability to innovate – defining innovativeness as an aspect of organisational culture. Based on ten c

The majority of prospective studies on alcohol use and mortality risk indicate that non-drinkers are at increased risk of death compared to moderate drinkers. This article investigates the association between middle-aged women's alcohol use and mortality, controlling for socio-demographic and health variables. An association between alcohol use and hospital in-patient care is also analysed. Method

We report measured quantized conductance and quasi-ballistic transport in selectively regrown In0.85Ga0.15As nanowires. Very low parasitic resistances obtained by regrowth techniques allow us to probe the near-intrinsic electrical properties, and we observe several quantized conductance steps at 10 K. We extract a mean free path of 180 +/- 40 nm and an effective electron mobility of 3300 +/- 300 c

Lactic acid bacteria (LAB) are of profound importance in food production and infection medicine. LAB do not rely on heme (protoheme IX) for growth and are unable to synthesize this cofactor but are generally able to assemble a small repertoire of heme-containing proteins if heme is provided from an exogenous source. These features are in contrast to other bacteria, which synthesize their heme or d

To evaluate the feasibility of delivering experimental radiation therapy to tumors in the mouse pancreas. Imaging and treatment were performed using combined CT (computed tomography)/orthovoltage treatment with a rotating gantry.

The aim of the study was to evaluate the anatomic suitability for endovascular abdominal aneurysm repair (EVAR) according to instructions for use (IFUs) of three commercially available bifurcated stent graft devices and explore the possible benefits of low-profile delivery systems. Computed tomography scans of 241 patients with abdominal aortic aneurysm (AAA) were evaluated for suitability of Zeni

Anti-C1q has been associated with systemic lupus erythematosus (SLE) and lupus nephritis in previous studies. We studied anti-C1q specificity for SLE (vs rheumatic disease controls) and the association with SLE manifestations in an international multicenter study.

Trifluoroacetic acid is a very strong carboxylic acid. The acid has been suspected to have similar toxic effects as hydrofluoric acid on skin contact. Hydrofluoric acid is highly toxic, owing to skin penetration by fluoride ions. A spill of hydrofluoric acid on the skin may be fatal. As trifluoroacetic acid contains fluorine, patients with chemical burns caused by trifluoroacetic acid have been gi

This review will discuss methodologies and applicability of key inflammatory models of respiratory disease in proof of concept or proof of efficacy clinical studies. In close relationship with these models, induced sputum and inflammatory cell counts will be addressed for phenotype-directed drug development. Additionally, important regulatory aspects regarding noninvestigational medicinal products

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

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

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

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

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

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
