Strain NL19T is a Gram negative aerobic bacterium that was isolated from sludge of a deactivated uranium mine in Portugal. 16S rRNA gene sequence analysis revealed that strain NL19T is a member of the genus Pedobacter and closely related to the strains Pedobacter himalayensis MTCC 6384T, Pedobacter cryoconitis DSM 14825T, Pedobacter westerhofensis DSM 19036T and P. hartonius DSM 19033T. It has a DNA G+C content of 40.8 mol%, which agreed with the genus description. The main fatty acids include C16:1 9c, C14:1 9c, C4:0, Iso-C17:0, Iso-C17:0 3-OH, C16:0, Anteiso-C15:0 and Iso-C15:0 3-OH...

Four bacterial strains, LFT 1.7T, LT2C 2.5, LT4C 2.8 and TM 4.6, were isolated from Great scallop (Pecten maximus) larvae and tank seawater in a Norwegian hatchery and characterized by a polyphasic approach including phenotypic, chemotaxonomic and genomic traits. All of them were Gram-negative and motile rods, oxidase and catalase positive and required sea salts for growth. Major fatty acids present were Summed Feature 3 (C16:1ω7c/C16:1 ω6c), Summed Feature 8 (C18:1ω7c or C18:1 ω6c), C16:0, C14:0, Summed Feature 2 (C14:0 3OH/C16:1 iso I), C12:0 3OH and C12:0...

: We assessed non-liver-related non-AIDS-related (NLR-NAR) events and mortality in a cohort of HIV/HCV-coinfected patients treated with interferon and ribavirin between 2000 and 2008. The censoring date was May 31, 2014. Cox regression analysis was performed to assess the adjusted hazard rate (HR) of overall death in responders and non-responders. Fine and Gray regression analysis was conducted to determine the adjusted sub-hazard rate (sHR) of NLR deaths and NLR-NAR events considering death as the competing risk...

Enzymes that modify and remodel chromatin act in broadly conserved macromolecular complexes. One key modification is the dynamic acetylation of histones and other chromatin proteins by opposing activities of acetyltransferase and deacetylase complexes. Among acetyltransferases, the NuA4 complex containing Tip60 or its Saccharomyces cerevisiae ortholog, Esa1, is of particular significance because of its roles in crucial genomic processes including DNA damage repair and transcription. The catalytic subunit Esa1 is essential, as are five non-catalytic NuA4 subunits...

RAS genes are mutated in 20% of human tumors, but these mutations are very rare in breast cancer. Here we used a mouse model to generate tumors upon activation of a mutagenic T2Onc2 transposon via expression of a transposase driven by the keratin K5 promoter in a p53+/- background. These animals mainly developed mammary tumors, most of which had transposon insertions in one of two RASGAP genes, neurofibromin1 (NF1) and RAS p21 protein activator (Rasa1). Immunohistochemical analysis of a collection of human breast tumors confirmed that low expression of RASA1 is frequent in basal (triple-negative) and ER-negative tumors...

BACKGROUND CONTEXT: Disc degeneration is associated with the progressive loss of the proteoglycan content of the intervertebral disc (IVD), decreased matrix synthesis, higher concentrations of proteolytic enzymes and increased levels of pro-inflammatory cytokines. In previous studies, we have shown that C-C chemokine ligand (CCL)2, CCL3, and CCL5 are highly expressed by cultured nucleus pulposus (NP) and annulus fibrosus (AF) cells that have been treated by interleukin (IL)-1. The major function for these chemokines is to recruit immune cells into the disc...

Neospora caninum is a parasite of the Apicomplexa phylum responsible for abortion and losses of fertility in cattle. As part of its intracellular cycle, the first interaction of the parasite with the target cell is performed with the surface proteins known as the SRS superfamily (Surface Antigen Glycoprotein - Related Sequences). SAG related or SRS proteins have been a target of intense research due to its immunodominant pattern, exhibiting potential as diagnostic and/or vaccine candidates. The aim of this study was the cloning, expression and characterization of the gene NcSRS67 of N...

The deficit of cholinergic activity is one of the main findings in Alzheimer's disease (AD), and is related to the synthesis of acetylcholine, and the hydrolysing enzymes, acetylcholinesterase and butyrylcholinesterase (BuChE). Together with the Apolipoprotein E-ε4 allele (ApoE-ε4), the BuChE-K variant has been proposed to increase AD risk in certain populations. In addition, this polymorphism has been associated with a lower capacity to attenuate β-amyloid aggregation. In the present study we explored the interaction of the BuChE-K variant with its activity in CSF, conventional AD biomarkers and ApoE genotype...

The distinction between healthcare-associated MRSA (HA-MRSA) and community-associated MRSA (CA-MRSA) infections has become increasingly blurred. We assessed the molecular characterization and antimicrobial resistance profile for MRSA isolates from blood. Most of all (81.9%) isolates are related to known HA-MRSA and CA-MRSA epidemic lineages, such as, USA300, USA400, USA600, USA800 and USA1100. This is the first multicenter study in Rio de Janeiro.

Microglia fulfill important immunological functions in the brain by responding to pathological stresses and modulating their activities according to pro- or anti-inflammatory stimuli. Recent evidence indicates that changes in metabolism accompany the switch in microglia activation state, favoring glycolysis over oxidative phosphorylation when cells exhibit a pro-inflammatory phenotype. Carbon monoxide (CO), a byproduct of heme breakdown by heme oxygenase, exerts anti-inflammatory action and affects mitochondrial function in cells and tissues...

Mastoparans, a class of peptides found in wasp venom, have significant effects following a sting as well as useful applications in clinical practice. Among these is their potential use in the control of micro-organisms that cause infectious diseases with a significant impact on society. Thus, the present study describes the isolation and identification of a mastoparan peptide from the venom of the social wasp Pseudopolybia vespiceps and evaluated its antimicrobial profile against bacteria (Staphylococcus aureus and Mycobacterium abscessus subsp...

BACKGROUND: Vaccination coverage is the usual metrics to evaluate the immunization programs performance. For the 10-valent pneumococcal conjugate (PCV10) vaccine, measuring the delay of vaccination is also important, particularly as younger children are at increased risk of disease. Routinely collected administrative data was used to assess the timeliness of PCV10 vaccination, and the factors associated with delay to receive the first and second doses, and the completion of the PCV10 3+1 schedule...

OBJECTIVE: Breast cancer is the most common type of cancer in women. This population-based cohort study aimed to examine the association between breast cancer in female schizophrenia patients and its association with the use of antipsychotics drugs. METHODS: All study subjects were selected from the Taiwan Insurance Claims Data (1998-2008). We compared the risk for breast cancer between female schizophrenia patients receiving antipsychotics (n=29,641) with female patients without any serious mental illnesses nor receiving antipsychotic drugs (n=59,282)...

INTRODUCTION: Muscle mass maybe a determining factor in the variability of spirometry results in individuals of the same sex and age who have similar anthropometric characteristics. The aim of this study was to determine the association between spirometric results from healthy individuals and their muscle mass assessed by dual energy X-ray absorptiometry (DEXA). METHODS: A sample of 161 women and 144 men, all healthy non-smokers, was studied. Ages ranged from18 to77years...

This short communication presents the proof-of-concept of a novel dielectrophoretic lab-on-chip for identifying/separating circulating tumor cells for purposes of liquid biopsy. The device consists of a polydimethylsiloxane layer, containing a microchannel, bonded on a glass substrate that holds two sets of planar interdigitated transducer electrodes. The lab-on-chip is operated at a frequency that enables dielectrophoretic force to sort cells, based on type, along the lateral direction. The operating frequency ensures attraction force toward the electrodes on cancer cells and repulsion force toward the center of the microchannel on other cells...

A new analytical method for the quantification of olive oil and palm oil in blends with other vegetable edible oils (canola, safflower, corn, peanut, seeds, grapeseed, linseed, sesame and soybean) using normal phase liquid chromatography, and applying chemometric tools was developed. The procedure for obtaining of chromatographic fingerprint from the methyl-transesterified fraction from each blend is described. The multivariate quantification methods used were Partial Least Square-Regression (PLS-R) and Support Vector Regression (SVR)...
