Long-term polarization of microglia upon α-synuclein overexpression in nonhuman primates

We have previously shown that persistent a-synuclein overexpression in ventral midbrain of marmoset leads to a distinctive neurodegenerative process and motor defects. The neurodegeneration was confined to caudate putamen dopaminergic fibers in animals overexpressing wild-type (wt) alpha-synuclein. However, A53T alpha-synuclein overexpression induced neurodegeneration that resulted in nigral dopam

Anthropometric characteristics and risk of lymphoid and myeloid leukemia in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Overweight and obesity have been suggested as a risk factor for leukemia. Impaired immune function associated with obesity, increased insulin-like growth factor-I activity and stimulating effects of leptin suggest a possible biological link between anthropometric measures and leukemia. However, evidence from epidemiological studies has been inconsistent. We examined the potential association betwe

Population-based estimates of common comorbidities and cardiovascular disease in ankylosing spondylitis.

OBJECTIVE:: To study the rate of common comorbidities and cardiovascular disease in ankylosing spondylitis (AS) patients compared with the general population seeking health care. METHODS:: This cohort study included 935 subjects (67% men) age ≥20 years, diagnosed with AS and the adult background population in southern Sweden. During 2004 to 2007 we recorded the occurrence of physicians' diagnostic

The breath of life - Womens' experiences of breathing adapted radiation therapy.

PURPOSE: To describe and analyze how women with breast cancer experience breathing adapted radiation therapy (BART) and to explore how women manage daily radiation therapy. METHOD: Individual interviews were conducted with 20 women treated with BART for breast cancer concerning their perception of radiation therapy. The transcribed interviews were analyzed using qualitative content analysis. RESUL

On MIMO performance enhancement with multi-sector cooperation in a measured urban environment

Capacity improvement of intrasite cooperative MIMO using all three 120 degree-sectors of a base station (BS) site is studied for the first time in a measured urban environment at 2.65GHz. The results show that the mean uplink capacity gain exceeds 40% in as much as 1/4 of the coverage area, relative to the best single-sector link with no cooperation. In addition, a simple simulation model is devel

Hard real-time guarantees in feedback-based resource reservations

Resource reservation is a technique that allows isolating applications from interfering among each other. In the most classic setting, this method requires the periodic allocation of a given budget of resource over time. However, in reality, the actual budget allocation may deviate from its ideal value. Examples of causes of this deviation are: the presence of a system tick, the usage of shared re

Melatonin heals the gut

Excess alcohol consumption and stress are suggested to be key elements in the development of gastrointestinal disorders (Konturek et al., 2011). Dysfunction of the small intestinal barrier function with increased permeability is a common clinical observation in patients with inflammatory bowel syndrome (IBS) and alcoholic liver disease (Sommansson et al., 2013b). Therapeutic administration of the

Abundance of Broad Bacterial Taxa in the Sargasso Sea Explained by Environmental Conditions but Not Water Mass

To explore the potential linkage between distribution of marine bacterioplankton groups, environmental conditions, and water mass, we investigated the factors determining the abundance of bacterial taxa across the hydrographically complex Subtropical Convergence Zone in the Sargasso Sea. Based on information from 16S rRNA gene clone libraries from various locations and two depths, abundances of th

Sensory-specific anomic aphasia following left occipital lesions: Data from free oral descriptions of concrete word meanings

The present study investigated hierarchical lexical semantic structure in oral descriptions of concrete word meanings produced by a subject (ZZ) diagnosed with anomic aphasia due to left occipital lesions. The focus of the analysis was production of a) nouns at different levels of semantic specificity (e.g., "robin"-"bird"-"animal") and b) words describing sensory or motor experiences (e.g., "blue

The outcome of 9 years of consecutive patch testing with 4,4'-diaminodiphenylmethane and 4,4'-diphenylmethane diisocyanate.

Background: Two outbreaks of allergic contact dermatitis caused by isocyanates at two companies in southern Sweden initiated a research project focusing on contact allergy to isocyanates. Within the project, there was an interest in determining how often contact allergy to the most common isocyanate, diphenylmethane-4,4'-diisocyanate (4,4'-MDI), occurred. Objectives: To determine and compare the

Global cancer surgery: delivering safe, affordable, and timely cancer surgery

Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, aff ordable, or timely surgery. This Commission on global ca

Relationships Between Commuting and Social Capital Among Men and Women in Southern Sweden.

The societal need for a mobile workforce increases time spent commuting and thus also the total workday. How this affects individual well-being and social life is, however, surprisingly little known. We investigated the relation between commuting time and mode, and social participation and general trust in other people as measures of social capital, using data from public health surveys conducted

Vigilant Keratinocytes Trigger PAMP Signaling in Response to Streptococcal M1 Protein.

The human skin exerts many functions in order to maintain its barrier integrity and protect the host from invading microorganisms. One such pathogen is Streptococcus pyogenes, which can cause a variety of superficial skin wounds that may eventually progress into invasive deep soft tissue infections. Here we show that keratinocytes recognize soluble M1 protein, a streptococcal virulence factor, as

Differential Effects of Efavirenz, Lopinavir/r, and Atazanavir/r on the Initial Viral Decay Rate in Treatment Naive HIV-1-Infected Patients

Initial viral decay rate may be useful when comparing the relative potency of antiretroviral regimens. Two hundred twenty-seven ART-naive patients were randomized to receive efavirenz (EFV) (n=74), lopinavir/ritonavir (LPV/r) (n=77), or atazanavir/ritonavir (ATV/r) (n=79) in combination with two NRTIs. The most frequently used NRTI combinations in the EFV and ATV/r groups were the nonthymidine ana

Search for Dark Matter in Events with Missing Transverse Momentum and a Higgs Boson Decaying to Two Photons in pp Collisions at root s=8 TeV with the ATLAS Detector

Results of a search for new phenomena in events with large missing transverse momentum and a Higgs boson decaying to two photons are reported. Data from proton-proton collisions at a center-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb(-1) have been collected with the ATLAS detector at the LHC. The observed data are well described by the expected standard model b

An explicit kernel-split panel-based Nyström scheme for integral equations on axially symmetric surfaces

A high-order accurate, explicit kernel-split, panel-based, Fourier–Nyström discretization scheme is developed for integral equations associated with the Helmholtz equation in axially symmetric domains. Extensive incorporation of analytic information about singular integral kernels and on-the-fly computation of nearly singular quadrature rules allow for very high achievable accuracy, also in the ev

Plasma alkylresorcinol metabolites as biomarkers for whole-grain intake and their association with prostate cancer: a Swedish nested case-control study.

Background:Observational studies have mostly found no association between self-reported whole-grain (WG) intake and prostate cancer (PCa). Plasma alkylresorcinol metabolites have been suggested as biomarkers for WG intake in free-living populations. Methods:We investigated the major dietary and lifestyle determinants of plasma alkylresorcinol metabolites in a nested case-control study (1,016 cases

Structure and Dynamics of Ribosomal Protein L12: An Ensemble Model Based on SAXS and NMR Relaxation

Ribosomal protein L12 is a two-domain protein that forms dimers mediated by its N-terminal domains. A 20-residue linker separates the N- and C-terminal domains. This linker results in a three-lobe topology with significant flexibility, known to be critical for efficient translation. Here we present an ensemble model of spatial distributions and correlation times for the domain reorientations of L1

Effects of Bile Salt Sodium Glycodeoxycholate on the Self-Assembly of PEO-PPO-PEO Triblock Copolymer P123 in Aqueous Solution.

A comprehensive experimental study on the interaction between the PEO-PPO-PEO block copolymer P123 (EO20PO68EO20) and the anionic bile salt sodium glycodeoxycholate (NaGDC) in water has been performed. The work was aimed at investigating the suitability of using P123 as bile salt sequestrant beside the fundamental aspects of PEO-PPO-PEO block copolymer-bile salt interactions. Various experimental

Spinal Cord Injury Enables Aromatic l-Amino Acid Decarboxylase Cells to Synthesize Monoamines.

Serotonin (5-HT), an important modulator of both sensory and motor functions in the mammalian spinal cord, originates mainly in the raphe nuclei of the brainstem. However, following complete transection of the spinal cord, small amounts of 5-HT remain detectable below the lesion. It has been suggested, but not proven, that this residual 5-HT is produced by intraspinal 5-HT neurons. Here, we show b
