The homeodomain transcription factor Nanog plays an important role in embryonic stem cell (ESC) self-renewal and is essential for acquiring ground-state pluripotency during reprogramming. Understanding how Nanog is transcriptionally regulated is important for further dissecting mechanisms of ESC pluripotency and somatic cell reprogramming. Here, we report that Nanog is subjected to a negative auto

cBN cutting tools with superior mechanical properties are widely used in machining various hard materials. The microgeometry of cBN cutting tools, such as the edge radius, has great influence on the surface quality of components and tool life. For optimized tool geometry, it is crucial to understand the influence of the cBN cutting tool microgeometry on the machined surface quality. In this study,

Cambodia has been growing rapidly over the past few years, but remains one of the poorest countries in East Asia. This paper analyzes rural poverty in Cambodia to identify the factors that explain its occurrence and persistence. The reduction of rural poverty in Cambodia requires (1) improvements in agricultural productivity and (2) the establishment of other income-earning opportunities for the r

OBJECTIVES: Poor self-rated health is an estimator of quality of life and a predictor of mortality seldom studied in immigrant populations. This work aimed to study self-rated health in relation to social capital, socioeconomic status, lifestyle and comorbidity in immigrants from Iraq - one of the largest non-European immigrant group in Sweden today - and to compare it with the self-rated health o

Background: Traumatic brain injury is a common reason not only for emergency visits worldwide but also for significant morbidity and mortality. Several clinical guidelines exist but adherence is generally low. Aim: To study attitudes toward computed tomography of the head among emergency department Change to physicians throughout the article who manage patients with trauma to the head and doctors'

This study investigates the 2007-2009 Fertile Crescent drought in the border region of Syria, Iraq and Turkey from an agricultural perspective using satellite based vegetation data combined with precipitation and land cover data. We look at the trends in vegetation productivity between 2001 and 2015, as well as the different politico-economic factors affecting land management leading up to the dro

The Southern California Borderland is a region that experiences strong natural variations in bottom water oxygen and pH. We use marine sediments from Santa Monica Basin to reconstruct environmental conditions in the basin's bottom water from the Last Glacial Maximum (LGM) to present. We then compare the records to the adjacent Santa Barbara Basin and Santa Lucia Slope. High-resolution records of b

The RNA-binding protein HuR promotes tumor growth by affecting proliferation, metastasis, apoptosis, and angiogenesis. Although immune cells, especially tumor-associated macrophages, are critical components of the tumor stroma, the influence of HuR in tumors on the recruitment of immune cells remains poorly understood. In the present study, we, therefore, aimed to elucidate the impact of tumor cel

Aims/hypothesis: Sleep duration is a risk factor for incident diabetes mellitus and CHD. The primary aim of the present study was to investigate, in sex-specific analyses, the role of incident diabetes as the possible biological mechanism for the reported association between short/long sleep duration and incident CHD. Considering that diabetes is a major risk factor for CHD, we hypothesised that a

Hydration is a key aspect of the skin that influences its physical and mechanical properties. Here, we investigate the interplay between molecular and macroscopic properties of the outer skin layer - the stratum corneum (SC) and how this varies with hydration. It is shown that hydration leads to changes in the molecular arrangement of the peptides in the keratin filaments as well as dynamics of C-

Background: The preference for sweet taste is partially genetically determined. The major allele of the single nucleotide polymorphism rs12033832 in the sweet taste receptor (TAS1R2) has previously been associated with lower sugar sensitivity and higher sugar intake among overweight individuals. The aim of the present study was to examine the association between dietary intake and the TAS1R2 genot

Differential migration has been extensively reported in spring, but less so in autumn, particularly in relation to sex in monomorphic bird species. Here, we analysed the autumn passage of a monomorphic, globally threatened passerine, the Aquatic Warbler Acrocephalus paludicola throughout Western Europe, with regard to age and sex. We showed that, overall, adults migrated earlier than first-year bi

The critical role of polyamines in key processes such as cell growth, differentiation and macromolecular synthesis makes the enzymes involved in their synthesis potential targets in the treatment of certain types of cancer and parasitic diseases. Here we present a study on the inhibition of human and Leishmania donovani ODC (ornithine decarboxylase), the first committed enzyme in the polyamine bio

A hypothesis on the mechanism of "salt-scaling" of porous building materials based on theories for frost heaving in soils and observations made by Powers and Helmuth /1953/ is described. Though the text mainly deals with cement based materials, the mechanism described should be valid for any brittle, porous material. A simplified calculation of possible scalings shows that the hypothesis predicts

Purpose: Soft tissue sarcomas (STS) account for less than 1% of all malignancies and constitute a heterogeneous tumor entity in which malignant fibrous histiocytomas (MFH) represent one-third and are characterized by a lack of type-specific differentiation. A defective mismatch repair (MMR) system cause the familial cancer syndrome hereditary non-polyposis colorectal cancer (HNPCC), and since occa

The needs of parents of hospitalized children have received some attention in the health literature, but few studies have compared parents' perceptions of needs with staff's ideas about parents' needs. The aim of this study was to examine differences between the perceptions of the needs of parents of hospitalized children held by staff - nurses, doctors and allied health staff, and parents in a 15

Objecives: To examine the short-term effect of nicotine on bone healing and osseointegration. Material and methods: Sixteen female rabbits were divided into two groups. The test group was exposed to nicotine tartrate for 8 weeks and the control group was exposed to placebo. Nicotine or placebo was administered via a miniosmotic pump and plasma cotinine levels were measured weekly. The pump deliver

Post-traumatic microalbuminuria may be caused by either charge- or size-selective alterations in the glomerular filtration barrier, or both, and/or to a reduction in proximal tubular protein reabsorption (PTR). This study was performed to elucidate the pathophysiology of the increases in glomerular permeability occurring in rats exposed to laparotomy or to laparotomy and muscle trauma. In anaesthe
