mTOR Inhibition Alleviates L-DOPA-Induced Dyskinesia in Parkinsonian Rats

The development of dyskinesia upon chronic L-DOPA treatment is a major complication for the management of the motor symptoms in Parkinson's disease (PD) patients. Efforts are made to understand the underlying mechanisms and identify targets for the pharmacological alleviation of dyskinesia without affecting the therapeutic effect of L-DOPA. Previous studies have shown that the mTOR pathway is hype

Representing part-whole relations in conceptual space

In this paper, we propose a cognitive semantic approach to represent part–whole relations. We base our proposal on the theory of conceptual spaces, focusing on prototypical structures in part–whole relations. Prototypical structures are not accounted for in traditional mereological formalisms. In our account, parts and wholes are represented in distinct conceptual spaces; parts are joined to form

Search for photonic signatures of gauge-mediated supersymmetry in 8 TeV pp collisions with the ATLAS detector

A search is presented for photonic signatures motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded by the ATLAS detector at the LHC, and explores models dominated by both strong and electroweak production of supersymmetric partner states. Four experimental signatures incorporating a

Difficulties and pitfalls in the laboratory diagnosis of bleeding disorders

. von Willebrand disease (VWD) is the most common inherited bleeding disorder, but variable severity and several classification types mean that diagnosis is often not straightforward. In many countries, the assays are not readily available and/or are not well standardized. The latest methods and the basis of VWD are discussed here, together with information from the international quality assessmen

Having to focus on doing rather than being-Nurse assistants' experience of palliative care in municipal residential care settings.

BACKGROUND: Palliative care should be provided, irrespective of setting to all patients facing a life-threatening illness and to their families. The situation and needs of older people differ from those of younger people since they often have several co-existing diseases and health complaints. This implies an extensive need for care and for longer periods of palliative care. The main providers of

Genetic variation in alcohol dehydrogenase (ADH1A, ADH1B, ADH1C, ADH7) and aldehyde dehydrogenase (ALDH2), alcohol consumption and gastric cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort

Studies that have examined the association between alcohol consumption and gastric cancer (GC) risk have been inconsistent. We conducted an investigation of 29 genetic variants in alcohol metabolism loci (alcohol dehydrogenase, ADH1 gene cluster: ADH1A, ADH1B and ADH1C; ADH7 and aldehyde dehydrogenase, ALDH2), alcohol intake and GC risk. We analyzed data from a nested case-control study (364 cases

Cisplatin-induced duplex dissociation of complementary and destabilized short GG-containing duplex RNAs.

The ability of the anticancer active drug cisplatin to exert biological activity through interference with nucleic acid function is well documented. Since kinetics play a key role in determining product distributions in these systems, methods for accurate documentation of reactivity serve the purpose to identify preferential metal binding sites. In the present study, the aim has been to further ex

Scaffolding bracing of composite bridges during construction

Relatively little bracing of steel girders can significantly reduce possible risk of buckling failures, before the composite action between steel and concrete occurs. This paper intended both experimentally and numerically, to study the torsional bracing performance of a typical type of scaffoldings commonly used in bridge construction. Minor improvements in the structure of the scaffoldings as we

Population-based data from the Swedish Colon Cancer Registry

Background Evaluating the external validity of clinical trials requires knowledge not only of the study population but also of a relevant reference population. The main aim of this study was to present data from a large, contemporary, population-based cohort of patients with colonic cancer. Methods Data on patients diagnosed between 2007 and 2011 were extracted from the Swedish Colon Cancer Regist

Beating Signals in 2D Spectroscopy: Electronic or Nuclear Coherences? Application to a Quantum Dot Model System

In 2D electronic spectroscopy, oscillatory signals have recently received increased attention. The key issue is the origin of such beating-whether it is vibrational or electronic. In analogy to the distinction between rephasing and nonrephasing contributions to 2D spectra, we separate signal components with positive and negative coherence beating frequency via a third Fourier transformation and co

Efficacy of RG1-VLP Vaccination against Infections with Genital and Cutaneous Human Papillomaviruses

Licensed human papillomavirus (HPV) vaccines, based on virus-like particles (VLPs) self-assembled from major capsid protein L1, afford type-restricted protection against HPV types 16/18/6/11 (or 16/18 for the bivalent vaccine), which cause 70% of cervical cancers (CxCas) and 90% of genital warts. However, they do not protect against less prevalent high-risk (HR) types causing 30% of CxCa, or cutan

Skin pigmentation provides evidence of convergent melanism in extinct marine reptiles.

Throughout the animal kingdom, adaptive colouration serves critical functions ranging from inconspicuous camouflage to ostentatious sexual display, and can provide important information about the environment and biology of a particular organism. The most ubiquitous and abundant pigment, melanin, also has a diverse range of non-visual roles, including thermoregulation in ectotherms. However, little

CO and O overlayers on Pd nanocrystals supported on TiO2(110)

We have prepared a model catalytic system by depositing Pd onto a TiO2(110) surface held at similar to 720 K. Scanning tunneling microscopy (STM) reveals well-defined Pd nanocrystals consisting of (111) top facets with {111} and {100} side facets. The Pd nanocrystals go down to about 10 nm in width and 1.3 nm in height. Top facets can be imaged with atomic resolution, indicating the absence of TiO

Glucagon-Like Peptide 1 Stimulates Insulin Secretion via Inhibiting RhoA/ROCK Signaling and Disassembling Glucotoxicity-Induced Stress Fibers

Chronic hyperglycemia leads to pancreatic beta-cell dysfunction characterized by diminished glucose-stimulated insulin secretion (GSIS), but the precise cellular processes involved are largely unknown. Here we show that pancreatic beta-cells chronically exposed to a high glucose level displayed substantially increased amounts of stress fibers compared with beta-cells cultured at a low glucose leve

AN INTERNAL RADIATION DOSIMETRY COMPUTER PROGRAM, IDAC 2.0, FOR ESTIMATION OF PATIENT DOSES FROM RADIOPHARMACEUTICALS.

The internal dosimetry computer program internal dose assessment by computer (IDAC) for calculations of absorbed doses to organs and tissues as well as effective doses to patients from examinations with radiopharmaceuticals has been developed. The new version, IDAC2.0, incorporates the International Commission on Radiation Protection (ICRP)/ICRU computational adult male and female voxel phantoms a
