A minimalistic all-atom approach to protein folding

Using simple sequence-based potentials, the folding properties of a designed three-helix-bundle protein, an alpha-helix and a beta-hairpin are studied. The three-helix-bundle protein is modelled using 5-6 atoms per amino acid and is found to undergo a first-order-like folding transition in which chain collapse and helix formation cannot be separated, which is in-accord with experimental data. The

Which psychological method is most effective for group treatment?

Abstract While outcome studies in pediatric obesity have received considerable attention, research on different components of effective interventions remains limited. Little is known which psychological method (i.e., behavior modification, cognitive behavior therapy and family therapy) is most useful or how the choice of program delivery (group/individual) influences the intervention outcomes. Gro

Efficacy and safety of olaparib monotherapy in germline BRCA1/2 mutation carriers with advanced ovarian cancer and three or more lines of prior therapy.

The efficacy and safety of olaparib, an oral poly(ADP-ribose) polymerase (PARP) inhibitor, was investigated in a subgroup of patients with germline BRCA1/2 mutated (gBRCA1/2m) advanced ovarian cancer who had received ≥3 prior lines of chemotherapy. Primary data from this Phase II study (Study 42, ClinicalTrials.govNCT01078662) have been reported previously.

Perturbed Insulin-like Growth Factor-1 (IGF-1) and IGF Binding Protein-3 Are Not Associated with Chronic Widespread Pain in Men: Results from the European Male Ageing Study.

OBJECTIVE: To determine whether perturbations of insulin-like growth factor-1 (IGF-1) and IGF binding protein-3 (IGFBP-3) were associated with the presence of chronic widespread pain (CWP) in men. METHODS: The European Male Ageing Study (EMAS) is an 8-center population-based study of men aged 40-79 years recruited from population registers. A questionnaire asked about the presence and duration of

Proghrelin peptides: Desacyl ghrelin is a powerful inhibitor of acylated ghrelin, likely to impair physiological effects of acyl ghrelin but not of obestatin A study of pancreatic polypeptide secretion from mouse islets.

BACKGROUND: Proghrelin, produced by the ghrelin (A-like) cells of the gastric mucosa, gives rise to cleavage products, including desacyl ghrelin, acyl ghrelin and obestatin. The products are thought to be secreted concomitantly. In an earlier study we found acyl ghrelin and obestatin, but not desacyl ghrelin, to suppress the release of hormones from isolated islets of mouse and rat pancreas. RESUL

Regulation of AMP-activated protein kinase by cAMP in adipocytes: Roles for phosphodiesterases, protein kinase B, protein kinase A, Epac and lipolysis.

AMP-activated protein kinase (AMPK) is an important regulator of cellular energy status. In adipocytes, stimuli that increase intracellular cyclic AMP (cAMP) have also been shown to increase the activity of AMPK. The precise molecular mechanisms responsible for cAMP-induced AMPK activation are not clear. Phosphodiesterase 3B (PDE3B) is a critical regulator of cAMP signaling in adipocytes. Here we

Costa Rica and Nicaragua before the International Court of Justice – Trying to work out the complicated relationship between law and the environment

Nicaragua and Costa Rica have twice turned to the International Court of Justice (ICJ) to resolve disputes related to environmental damage occurring in a transboundary context. In these two cases the Court has to consider at least two issues. The first issue concerns the territorial status of a disputed border area. The disagreement is triggered by natural variations of the San Juan River at the b

Phagocytic properties in tumor astrocytes.

In glioblastoma multiforme (GBM), the pathophysiological events preceding and promoting an uncontrolled and remarkable growth is largely unknown. Studies on gliomas and macrophage expression have shown high levels of phagocytic cells, that is, microglial cells. It has also been demonstrated that human astrocytic cells and rat glioma cells are capable of phagocytosis. The purpose of this study was

Spatial variability and temporal trends in water-use efficiency of European forests

The increasing carbon dioxide (CO2) concentration in the atmosphere in combination with climatic changes throughout the lastcentury are likely to have had a profound effect on the physiology of trees: altering the carbon andwater fluxes passing throughthe stomatal pores. However, the magnitude and spatial patterns of such changes in natural forests remain highly uncertain.Here, stable carbon isoto

Social capital, political trust and experience of cannabis smoking: A population-based study in southern Sweden.

OBJECTIVE: To investigate whether political mistrust in the Riksdag (the national parliament in Sweden) is an independent characteristic of cannabis smokers, or whether it reflects low confidence in people in general, and therefore low social capital. METHOD: The 2004 public health survey in Skåne is a cross-sectional postal questionnaire study answered by 27,757 respondents aged 18-80 with a 59%

Cultural Analyses in Urban Theory of 1990s

In the 1990s, cultural analyses have become an integrated part of urban theory, and culture is often seen as an important factor in the interpretation of both the structural changes of society and the multiplicity of life forms. But culture is not only used as a means to understand actual changes; equally often it is used as a tool to create changes. Under the headings of culture and space, cultur

The Invisible Landscapes : The Construction of New Subjectivities in the Era of the Mobile Telephone

The interventions of portable digital devices such as mobile telephones, mp3 players, PDAs and many others, have contributed to the formation of contemporary notions of space. The impact of these devices' mobility (informing the users' mobility) could even be paralleled to the shift from the effects of still photography to those of film in the 19th century. Especially important for the perspective

Long-term follow-up of patients with uveitis associated with juvenile idiopathic arthritis: a cohort study.

PURPOSE: To analyze the clinical and visual outcome of 55 consecutive patients with juvenile idiopathic arthritis (JIA)-associated uveitis examined 7 and 24 years after the onset of the eye disease. METHODS: A retrospective study. RESULTS: Fifty-five out of 350 patients with JIA developed uveitis (15.7%). Forty-six (84%) of these had oligoarthritis, 6 (11%) had polyarthritis, and 3(5%) had systemi
