We screened promoter region of the telomerase reverse transcriptase (TERT) for activating somatic mutations in 188 tumors from patients with clear cell renal cell carcinoma (ccRCC). Twelve tumors (6.4%) carried a mutation within the core promoter region of the gene. The mutations were less frequent in high grade tumors compared to low grade tumors [odds ratio (OR)=0.15, 95% confidence interval (CI

The clinical presentation of type 1 diabetes is preceded by a prodrome of beta cell autoimmunity. We probed the short period of subtle metabolic abnormalities, which precede the acute onset of diabetes in the spontaneously diabetic BB rat, by analyzing the serum metabolite profile detected with combined gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS

Emission trading schemes (ETS) have emerged as a popular climate policy measure and are increasingly advocated as policy instruments to support the transition to a green economy. Using complementary analytical methods, this research investigated the institutional developments and complexities of the New Zealand Emissions Trading Scheme (NZ ETS). It focuses on (1) institutional experience and admin

Well-preserved marine fossils in carbonate rocks permit detailed studies of the end-Permian extinction event in the marine realm. However, the rarity of fossils in terrestrial depositional environments makes it more challenging to attain a satisfactory degree of resolution to describe the biotic turnover on land. Here we present new sedimentological, paleontological and geochemical (X-ray fluoresc

In the Southern part of Hanoi, high ammonium (NH4 + ) concentrations in reducing groundwater have been an issue over the last 25 years. Elevated NH4 + concentrations in groundwater, in general, are an indicator of influences from anthropogenic sources, but the buried peat layers in the Red River delta formation are also hypothesized to contribute to the high NH4 + levels (up to 100 mg/l). We trace

The long-term prognosis of patients with ST-elevation myocardial infarction (STEMI) aged 45years or younger and differences according to gender have not been well characterized.

To evaluate prospectively the association between serological markers of selected infections, including HPV, and risk of developing cervical cancer (CC) and precancer, we performed a nested case-control study within the European Prospective Investigation into Cancer and Nutrition (EPIC) study that included 184 cases of invasive CC (ICC), 425 cases of cervical intraepithelial neoplasia (CIN) grade

The Bronze Age of Eurasia (around 3000-1000 BC) was a period of major cultural changes. However, there is debate about whether these changes resulted from the circulation of ideas or from human migrations, potentially also facilitating the spread of languages and certain phenotypic traits. We investigated this by using new, improved methods to sequence low-coverage genomes from 101 ancient humans

We analyzed the influence of donor killer-cell immunoglobulin-like receptor (KIR) gene haplotypes on the risk of relapse and probability of event-free survival (EFS) in children with acute lymphoblastic leukemia (ALL) who received HLA-haploidentical transplantation of ex vivo T-cell depleted peripheral blood stem cells. The KIR gene haplotype was evaluated in 85 donors and the KIR B-content score

OBJECTIVE: The concordance index (c-index) is the standard way of evaluating the performance of prognostic models in the presence of censored data. Constructing prognostic models using artificial neural networks (ANNs) is commonly done by training on error functions which are modified versions of the c-index. Our objective was to demonstrate the capability of training directly on the c-index and t

The current paper considers the asymptotic local power of second-generation panel unit root tests that are robust to the presence of cross-section dependence in the form of common factors. As a basis for our analysis, we take the PANIC approach of Bai and Ng (A PANIC Attack on Unit Roots and Cointegration, Econometrica 72, 1127–1177, 2004; Panel Unit Root Tests with Cross-Section Dependence: A Fur

MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression. There have been several reports of miRNA deregulation in prostate cancer and the biological evidence for an involvement of miRNAs in prostate tumorigenesis is increasing. In this study, we show that miR-34c is downregulated in prostate cancer (p = 0.0005) by performing qRT-PCR on 49 TURPs from prosta

Since the formulation of the mobilities paradigm, research has shown that movement is increasingly at the heart of our social identities. This paper argues that mobility, and indeed, hypermobility, constitutes to a growing extent who we are, whilst societal perspectives on mobility increasingly dictate how we need to move in time and space in order to accrue network capital. In this critical revie

Current optical space telescopes rely upon silicon charge-coupled devices (CCDs) to detect and image the incoming photons. The performance of a CCD detector depends on its ability to transfer electrons through the silicon efficiently, so that the signal from every pixel may be read out through a single amplifier. This process of electron transfer is highly susceptible to the effects of solar proto

In order to find previously unknown subgroups in biomedical data and generate testable hypotheses, visually guided exploratory analysis can be of tremendous importance. In this paper we propose a new dissimilarity measure that can be used within the Multidimensional Scaling framework to obtain a joint low-dimensional representation of both the samples and variables of a multivariate data set,

Prostaglandin D(2) (PGD(2)), released through mast cell activation, is used as a non-invasive biomarker in patients with asthma. Since PGD(2) can elicit opposing effects on airway tone via activation of the PGD(2) receptors DP(1) and DP(2) as well as the thromboxane receptor TP, the aim of this study was to characterize the receptors that are activated by PGD(2) in the guinea pig lung parenchyma.

Invasive species and bottom-water hypoxia both constitute major global threats to the diversity and integrity of marine ecosystems. These stressors may interact with unexpected consequences, as invasive species that require an initial environmental disturbance to become established can subsequently become important drivers of ecological change. There is recent evidence that improved bottom-water o

There is accumulating evidence that gestational diabetes (GDM) is a growing problem. The lack of internationally standardized diagnostic procedures prevents consistent diagnosis and the burden of GDM must be determined in country-specific studies. In southern Sweden, GDM is defined as a 2-hour capillary plasma glucose concentration of ≥10.0 mmol/L during a universal 75 g oral glucose tolerance tes
