The product of the crgA gene of Streptomyces coelicolor represents a novel family of small proteins. A single orthologous gene is located close to the origin of replication of all fully sequenced actinomycete genomes and borders a conserved gene cluster implicated in cell growth and division. In S. coelicolor, CrgA is important for coordinating growth and cell division in sporogenic hyphae. In thi

BRCA1 mutation carriers have up to 80% life-time risk of developing breast cancer and 20-40% risk of developing ovarian cancer. High LH levels have been linked to increased risks of both breast and ovarian cancers in some studies and it is unknown whether gonadotropin levels are associated with BRCA1 mutation status. The aim of the study was to explore whether gonadotropin levels were associated w

1. Hormone-mediated maternal effects and developmental plasticity are important sources of phenotypic variation, with potential consequences for trait evolution. Yet our understanding of the importance of maternal hormones for offspring fitness in natural populations is very limited, particularly in non-avian species. 2. We experimentally elevated yolk testosterone by injection of a physiologica

We have investigated the pH dependence for each individual redox transition in the S-cycle of the oxygen evolving complex (OEC) of photosystem II by electron paramagnetic resonance (EPR) spectroscopy. In the experiments, OEC is advanced to the appropriate S-state at normal pH. Then, the pH is rapidly changed, and a new flash is given. The ability to advance to the next S-state in the cycle at diff

Objective To examine physical capacity (aerobic capacity, joint mobility, muscle function, and standing balance) in women with primary Sjögren's syndrome (primary SS) and to examine the correlation of aerobic capacity with fatigue, functional disability, and mental aspects (anxiety and depression). Methods Fifty-one women who fulfilled the European Community criteria for primary SS and who had an

Levels of plasma DNA concentrations in cancer patients have been shown to be higher than the plasma DNA concentrations found in healthy subjects. The value of plasma DNA levels for development of neoplastic or pulmonary disease was evaluated in a large prospective study. Plasma samples (n = 1, 184) were analyzed from 776 controls, 359 cases of cancer (lung, bladder, oral cavity, pharynx, larynx, l

An isochromosome of the long arm of chromosome 17, i(17q), is the most frequent genetic abnormality observed during the disease progression of Philadelphia chromosome-positive chronic myeloid leukemia (CML), and has been described as the sole anomaly in various other hematologic malignancies. The i(17q) hence plays a presumably important pathogenetic role both in leukemia development and progressi

Solutions of n-nonyl-beta-D-glucoside (C(9)G(1)), n-decyl-beta-D-glucoside (C(10)G(1)), n-dodecyl-beta-D-maltoside (C(12)G(2)) n-tetradecyl-beta-D-maltoside (C(14)G(2)) and C(9)G(1)/C(10)G(1) mixtures have been characterised by capillary viscometry and rheology in H2O and D2O, in order to map the influence of surfactant characteristics on micellisation over a wide concentration range. For the malt

Physical activity is regarded as an important component of a healthy lifestyle. Several social and environmental factors have systematically emerged as barriers to low leisure time physical activity (LTPA), for example, lack of money, low social support due to lack of supportive family or friends, and living in high crime rate areas. Low LTPA has been found to be strongly associated with low socio

Aims: To determine the number of patients needed to be screened (NNS) and allocated (NNA) in order to include one participant in a randomized clinical trial (RCT), and to compare the characteristics of patients accepting or declining participation in the RCT. Methods: The recruitment process of an ongoing multicenter RCT, comparing surgical and non-surgical interventions after acute anterior cruci

Excited states have been studied in Ar-35 following the O-16(Mg-24,1alpha1n)Ar-35 fusion-evaporation reaction at 60 MeV using the Ge-detector array GASP. A comparison with the mirror nucleus Cl-35 shows two remarkable features: (i) A surprisingly large energy difference for the 13/2(-) states, in which the hitherto overlooked electromagnetic spin-orbit term is shown to play a major role, and (ii)

Cat's Claw (Uncaria tomentosa) water extracts, essentially free of oxindole alkaloids, have been shown to possess a broad spectrum of biological activity including DNA repair enhancement and antiinflammatory properties. These two biological mechanisms are key molecular targets to develop treatments that protect skin exposed to ultraviolet light from the sun. Because C-Med-100, a Cat's Claw water e

Overall migration speed is likely to be a trait under selection pressure in animals migrating annually between habitats for reproduction and survival. A general expression was used for migration speed (V-migr), accounting for energy accumulation and transport, and derive how V-migr scales with body mass for three types of migratory locomotion: running, swimming and flying (powered and soaring flig

OBJECTIVES: The sensitizing properties of organic acid anhydrides (OAA) were evaluated in a rat model. METHODS: The development of specific immunoglobulin (Ig)E and Ig G in serum was investigated after immunization with 14 OAA and 3 OAA conjugates. Brown Norway rats were injected intradermally with 0.1 ml of 0.2 M OAA in liquid paraffin or 1.4 mg of rat serum albumin conjugate in saline. Serum sam

There have been contradictory reports on the shift in the T-cell cytokine expression pattern of peripheral blood mononuclear cells from patients with atopic dermatitis (AD); more specifically the interleukin (IL)-4 and interferon (IFN)-gamma profiles. The aim of this study was to shed further light on this contradiction by measuring the intracellular cytokines IL-4 and IFN-gamma by flow cytometry

The common approach for constructing factor mimicking portfolios is to go long in assets with high loadings and to short-sell those with low loadings on some background factors. As a result portfolios containing stocks with low loading on the background factor receive negative betas against the corresponding mimicking portfolio. Thus, such portfolios appear as hedges against the background risk an

Evidence for a novel route of adult hematopoietic stem cell lineage commitment through Lin(-)Sca-1(+)Kit(+)Flt3(hi) (LSKFlt3(hi)) lymphoid-primed multipotent progenitors (LMPPs) with granulocyte/monocyte (GM) and lymphoid but little or no megakaryocyte/erythroid (MkE) potential was recently challenged, as LSKFlt3(hi) cells were reported to possess MkE potential. Herein residual (1-2%) MkE potentia
