DNA Glycosylases Involved in Base Excision Repair May Be Associated with Cancer Risk in BRCA1 and BRCA2 Mutation Carriers.

Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of synthetic lethality that exists between one of the components of the BER pathway, PARP1 (poly ADP ribose polymerase), and both BRCA1 and BRCA2. In the p

Mapping the New Molecular Landscape: Social Dimensions of Epigenetics

Epigenetics is the study of changes in gene expression caused by mechanisms other than changes in the DNA itself. The field is rapidly growing and being widely promoted, attracting attention in diverse arenas. These include those of the social sciences, where some researchers have been encouraged by the resonance between imaginaries of development within epigenetics and social theory. Yet, sustain

Pinpointing oxidative modifications in proteins-recent advances in analytical methods

Oxidation is one of the key degradation pathways in proteins and is of relevance to analyze in a wide variety of research disciplines. The types of different modifications occurring during oxidation by reactive oxygen species (ROS) are almost as many as the number of available analytical methods. Protein oxidation in biological samples has traditionally been analyzed by various protein carbonyl as

Suppressor of cytokine signaling 2 (SOCS2) associates with FLT3 and negatively regulates downstream signaling.

The suppressor of cytokine signaling 2 (SOCS2) is a member of the SOCS family of E3 ubiquitin ligases. SOCS2 is known to regulate signal transduction by cytokine receptors and receptor tyrosine kinases. The receptor tyrosine kinase FLT3 is of importance for proliferation, survival and differentiation of hematopoietic cells and is frequently mutated in acute myeloid leukemia. We observed that SOCS2

TFEB: Pathogenic role and therapeutic target in Parkinson disease.

Parkinson disease (PD) is characterized by the progressive loss of nigral dopamine neurons and the presence of accumulations containing the disease-causing protein SNCA/α-synuclein. Here we review our recent findings describing how SNCA impairs the function of the master regulator of the autophagy-lysosomal pathway (ALP), the transcription factor EB (TFEB), and that genetic or pharmacological stim

Nivolumab in Previously Untreated Melanoma without BRAF Mutation

BACKGROUND Nivolumab was associated with higher rates of objective response than chemotherapy in a phase 3 study involving patients with ipilimumab-refractory metastatic melanoma. The use of nivolumab in previously untreated patients with advanced melanoma has not been tested in a phase 3 controlled study. METHODS We randomly assigned 418 previously untreated patients who had metastatic melanoma w

Nephrogenic systemic fibrosis and gadolinium-based contrast media: updated ESUR Contrast Medium Safety Committee guidelines

To update the guidelines of the Contrast Media Safety Committee (CMSC) of the European Society of Urogenital Radiology (ESUR) on nephrogenic systemic fibrosis and gadolinium-based contrast media. Topics reviewed include the history, clinical features and prevalence of nephrogenic systemic fibrosis and the current understanding of its pathophysiology. The risk factors for NSF are discussed and prop

Gene-Lifestyle Interaction and Type 2 Diabetes: The EPIC InterAct Case-Cohort Study.

Understanding of the genetic basis of type 2 diabetes (T2D) has progressed rapidly, but the interactions between common genetic variants and lifestyle risk factors have not been systematically investigated in studies with adequate statistical power. Therefore, we aimed to quantify the combined effects of genetic and lifestyle factors on risk of T2D in order to inform strategies for prevention.

Experimentally determined vs. Monte Carlo simulated peak-to-valley ratios for a well-characterised n-type HPGe detector.

Measurements and simulations to investigate the contributing factors to the peak-to-valley (PTV) ratio have been both experimentally determined as well as Monte Carlo simulated for a well-characterised HPGe n-type detector together with a Cs-137 gamma source encapsulated in thin polystyrene. Measurements were carried out in a low-background gamma counting facility at Lund University. The results o

The undulation force; theoretical results versus experimental demonstrations.

In 1978 Wolfgang Helfrich published a paper (Helfrich W. Z Naturforsch 1978; 33a:305) where he introduced the notion of an undulation force between bilayers. This is caused by thermal excitations of the bending modes being restricted by the presence of neighboring layers. Although there is now a consensus on the qualitative picture put forward by Helfrich there is still a debate concerning the qua

How Climate Change Affects Extremes in Maize and Wheat Yield in Two Cropping Regions

Downscaled climate model projections from phase 5 of the Coupled Model Intercomparison Project (CMIP5) were used to force a dynamic vegetation agricultural model (Agro-IBIS) and simulate yield responses to historical climate and two future emissions scenarios for maize in the U.S. Midwest and wheat in southeastern Australia. In addition to mean changes in yield, the frequency of high- and low-yiel

Inhaled Corticosteroid/Long-Acting beta(2)-Agonist Combination Therapy for Asthma: Attitudes of Specialists in Europe

Background: As new combinations of inhaled corticosteroids (ICSs) and long-acting beta(2)-agonists (LABAs) become available for the treatment of asthma, it will be important to determine criteria against which they can be evaluated. The aim of this study was to assess which attributes of combination therapy physicians consider most important. Methods: Primary and secondary care asthma specialists

"Jag söker ett värdelöst guld/ ett guld som gör värdelöst/ guldet, allt guld!" : några ingångar till den litterära värdediskurens labryrint

This article examines the modern concept of literary value. Since the late 18th century, the problem of literary value has been regarded, from the point of view of the so called double discourse of value, as a presupposed opposition between material and spiritual ”economies”. Many Romanticist and Modernist authors believe that literature – and in a broader sense art and aesthetics – constitute a v

Wall of cash: The investment-cash flow sensitivity when capital becomes abundant

In the mid 2000s the oil and gas industry was hit by what might be best described as a 'wall of cash' as oil prices successively reached new record levels and access to external financing improved greatly. In this article we investigate what this sudden abundance of liquidity implied for the investment-cash flow relationship, the interpretation of which continues to generate controversy in the lit

Three very old men's experiences of mobility device use over time.

Abstract Aim: The aim of this study was to explore experiences of mobility device (MD) use among very old single-living Swedish men. Methods: A multiple case study of three men, involving quantitative and qualitative data, was used in an embedded mixed methods design and presented in three narrative stories. To capture differences and similarities in the use of MDs a cross-case analysis was conduc
