alpha-Helical coiled coil structures, which are noncovalently associated heptad repeat peptide sequences, are ubiquitous in nature. Similar amphipathic repeat sequences have also been found in helix-containing proteins and have played a central role in de novo design of proteins. In addition, they are promising tools for the construction of nanomaterials. Small-angle X-ray scattering (SAXS) has em

Maternal diet during pregnancy has been proposed to increase the risk of autoimmune diseases.

In 2006 ESO Council authorized a Phase B study of a European AO-telescope with a 42 m segmented primary with a 5-mirror design, the E-ELT Several reports and working groups have already presented science cases for an E-ELT, specifically exploiting the new capabilities of such a large telescope. One of the alms of the design has been to find a balance in the performances between an E-ELT and the Ja

Water and energy are inextricably linked, and as a consequence both have to be addressed together. This is called the water-energy nexus. When access to either is limited, it becomes obvious that it is necessary to consider their interdependence. Population growth, climate change, urbanization, increasing living standards and food consumption will require an integrated approach where food, water a

Gene amplification is relatively common in tumors. In certain subtypes of sarcoma, it often occurs in the form of ring and/or giant rod-shaped marker (RGM) chromosomes whose mitotic stability is frequently rescued by ectopic novel centromeres (neocentromeres). Little is known about the origin and structure of these RGM chromosomes, including how they arise, their internal organization, and which s

Understanding the degree of genetic population differentiation is important in conservation genetics for inferring gene flow between populations and for identifying small and isolated threatened populations. We evaluated the genetic variation within and between three populations of the rock firefinch (Lagonosticta sanguinodorsalis), a range restricted firefinch endemic to Nigeria and Cameroon. The

Malignant melanoma (MM) patients are being treated with an increasing number of personalized medicine (PM) drugs, several of which are small molecule drugs developed to treat patients with specific disease genotypes and phenotypes. In particular, the clinical application of protein kinase inhibitors (PKI) has been highly effective for certain subsets of MM patients. Vemurafenib, a PKI targeting BR

Semiconductor nanowires are great candidates for building novel electronic devices. Considering the cost of fabricating such devices, substrate reuse and gold consumption are the main concerns. Here we report on implementation of high throughput gold electrodeposition for selective deposition of metal seed particles in arrays defined by lithography for nanowire synthesis. By use of this method, a

Traditional approaches for understanding environmental governance - such as environmental policy analysis or natural resources management - do not adequately address the gamut of human-natural system interactions within the context of the complex biogeophysical cycles and processes of the planet. This is perhaps more so in the African regional context where the complex relationships between modern

A decade ahead of their time, von Schantz et al. united sexual selection and free radical biology by identifying causal links between deep-rooted physiological processes that dictate resistance to toxic waste from oxidative metabolism (reactive oxygen species, ROS), and phenotypic traits, such as ornaments. Ten years later, these ideas have still only been tested with indirect estimates of free ra

All women in the South Sweden Health Care Region with breast cancer diagnosed aged less than 41 during the period between 1990 and 1995 were contacted in 1996 and offered germline mutation analysis of the BRCA1 and BRCA2 genes. Mutation carriers (n = 20) were compared with noncarriers (n = 201) for overall survival (OS) and risk of contralateral breast cancer (CBC). Mutation carriers were younger

Norovirus is a major cause of gastroenteritis and hospital outbreaks, leading to substantial morbidity and direct healthcare expenses as well as indirect societal costs. The aim of the study was to estimate the proportion of nosocomial norovirus infections among inpatients tested positive for norovirus in Denmark, 2002-2010, and to study the distribution of norovirus genotypes among inpatients wit

The recently described oomycete pathogen Phytophthora pisi causes root rot on pea and faba bean, while the closely related Phytophthora sojae is the causal agent of soybean root and stem rot. Differences in the pathogenicity factor repertoires that enable the two species to have distinct host specificity towards pea and soybean, were studied using tandem mass spectrometry in a global proteome stud

There exist major challenges in accelerating the spatial data infrastructure (SDI) planning process in the developing countries as well as advocating for politicians to support the development of SDI, due to the high complexity of SDI, lack of knowledge and experience, and limited insight in the benefits. To address these challenges, a methodology for SDI planning in Tanzania, based on the system

To estimate the relationship between heredity and proband's age/parity on the risk of undergoing surgery for pelvic organ prolapse and stress incontinence. Study design: Swedish population based study. Data from two national Swedish registers were used: the Hospital Discharge Register, National Board of Health and Welfare, containing information on all in-patient surgical procedures on Swedish hos

Further formulations of mometasone furoate are needed for treatment of patients with plaque psoriasis to meet individual patient preferences. This has motivated the development of Ovixan(A (R)) (Galencia, Malmoe, Sweden), a formulation of mometasone furoate with different cosmetic properties than the commonly used formulation, Elocon(A (R)) (Merck [Schering Plough], Whitehouse Station, New Jersey,

Flow coefficients nu(n) for n = 2, 3, 4, characterizing the anisotropic collective flow in Au + Au collisions at root s(NN) = 200 GeV, are measured relative to event planes Psi(n), determined at large rapidity. We report nu(n) as a function of transverse momentum and collision centrality, and study the correlations among the event planes of different order n. The nu(n) are well described by hydrod
