Consensus HIV-1 subtype A integrase and its raltegravir-resistant variants: Design and characterization of the enzymatic properties.

Model studies of the subtype B and non-subtype B integrases are still required to compare their susceptibility to antiretroviral drugs, evaluate the significance of resistance mutations and identify the impact of natural polymorphisms on the level of enzymatic reactivity. We have therefore designed the consensus integrase of the HIV-1 subtype A strain circulating in the former Soviet Union territo

Genome-wide meta-analysis identifies five new susceptibility loci for cutaneous malignant melanoma.

Thirteen common susceptibility loci have been reproducibly associated with cutaneous malignant melanoma (CMM). We report the results of an international 2-stage meta-analysis of CMM genome-wide association studies (GWAS). This meta-analysis combines 11 GWAS (5 previously unpublished) and a further three stage 2 data sets, totaling 15,990 CMM cases and 26,409 controls. Five loci not previously asso

Targeting HMG-CoA reductase with statins in a window-of-opportunity breast cancer trial.

Lipophilic statins purportedly exert anti-tumoral effects on breast cancer by decreasing proliferation and increasing apoptosis. HMG-CoA reductase (HMGCR), the rate-limiting enzyme of the mevalonate pathway, is the target of statins. However, data on statin-induced effects on HMGCR activity in cancer are limited. Thus, this pre-operative study investigated statin-induced effects on tumor prolifera

The Role of Social Work in Cross-Professional Teamwork: Examples from an Older Peoples Team in England

There are numerous of challenges confronting social work with older people. In Sweden, this is scarcely discussed, which is interesting in light of the radical organisational change in 1992, when all eldercare became a municipal responsibility governed by the Social Service Act. At this point in time, a decisive change was also introduced in England. The legislative changes have had a major impact

Early-stage cervical cancer: Tumor delineation by magnetic resonance imaging and ultrasound - A European multicenter trial

Objective. To compare the diagnostic accuracy of ultrasound (US) and magnetic resonance imaging (MRI) in the preoperative assessment of early-stage cervical cancer using pathologic findings as the reference standard. Patients and methods. Prospective multi-center trial enrolling 209 consecutive women with early-stage cervical cancer (FIGO IA2-IIA) scheduled for surgery. The following parameters we

Functional traits as indicators of biodiversity response to land use changes across ecosystems and organisms

Rigorous and widely applicable indicators of biodiversity are needed to monitor the responses of ecosystems to global change and design effective conservation schemes. Among the potential indicators of biodiversity, those based on the functional traits of species and communities are interesting because they can be generalized to similar habitats and can be assessed by relatively rapid field assess

Cross-sectional scanning tunneling microscopy and spectroscopy of semimetallic ErAs nanostructures embedded in GaAs

The growth and atomic/electronic structure of molecular beam epitaxy-grown ErAs nanoparticles and nanorods embedded within a GaAs matrix are examined for the first time via cross-sectional scanning tunneling microscopy and spectroscopy. Cross sections enable the interrogation of the internal structure and are well suited for studying embedded nanostructures. The early stages of embedded ErAs nanos

Cerebrospinal fluid inflammatory markers in Parkinson's disease - Associations with depression, fatigue, and cognitive impairment.

Neuroinflammation may be involved in the pathophysiology of Parkinson's disease (PD) and specifically in non-motor symptoms such as depression, fatigue and cognitive impairment. The aim of this study was to measure inflammatory markers in cerebrospinal fluid (CSF) samples from PD patients and a reference group, and to investigate correlations between non-motor symptoms and inflammation. We quantif

Hypersensitivity reactions to metallic implants-diagnostic algorithm and suggested patch test series for clinical use.

Cutaneous and systemic hypersensitivity reactions to implanted metals are challenging to evaluate and treat. Although they are uncommon, they do exist, and require appropriate and complete evaluation. This review summarizes the evidence regarding evaluation tools, especially patch and lymphocyte transformation tests, for hypersensitivity reactions to implanted metal devices. Patch test evaluation

Platelets regulate P-selectin expression and leukocyte rolling in inflamed venules of the pancreas

Recent data suggest that platelets regulate inflammatory changes and tissue damage in acute pancreatitis although the role of platelets in leukocyte-endothelium interactions in the pancreatic microcirculation is not known. The aim of this study was to define the impact of platelets on leukocyte rolling and adhesion in acute pancreatitis. Acute pancreatitis was induced in C57BL/6 mice by caerulein

Cellobiose Dehydrogenase Aryl Diazoniunn Modified Single Walled Carbon Nanotubes: Enhanced Direct Electron Transfer through a Positively Charged Surface

One of the challenges in the field of biosensors and biofuel cells is to establish a highly efficient electron transfer rate between the active site of redox enzymes and electrodes to fully access the catalytic potential of the biocatalyst and achieve high current densities. We report on very efficient direct electron transfer (DET) between cellobiose dehydrogenase (CDH) from Phanerochaete sordida

Laccase detoxification mediates the nutritional alliance between leaf-cutting ants and fungus-garden symbionts

Leaf-cutting ants combine large-scale herbivory with fungus farming to sustain advanced societies. Their stratified colonies are major evolutionary achievements and serious agricultural pests, but the crucial adaptations that allowed this mutualism to become the prime herbivorous component of neotropical ecosystems has remained elusive. Here we show how coevolutionary adaptation of a specific enzy

Adolescents selling sex: Exposure to abuse, mental health, self-harm behaviour and the need for help and support-a study of a Swedish national sample

Svensson F, Fredlund C, Svedin CG, Priebe G, Wadsby M. Adolescents selling sex: Exposure to abuse, mental health, self-harm behaviour and the need for help and support-a study of a Swedish national sample. Nord J Psychiatry 2013; 67: 81-88. Background: Selling sex is not uncommon among adolescents and we need to increase our knowledge of how this affects them. Aim: The aim of this study was to inv

Individuality in bird migration: routes and timing

The exploration of animal migration has entered a new era with individual-based tracking during multiple years. Here, we investigated repeated migratory journeys of a long-distance migrating bird, the marsh harrier Circus aeruginosus, in order to analyse the variation within and between individuals with respect to routes and timing. We found that there was a stronger individual repeatability in ti
