BACKGROUND: Articular infection is an orthopedic challenge due to its difficult diagnosis and devastating results. Various diagnostic studies exist: culture, ESR, CRP, count of leukocytes, among others, but none is specific, they all take more than 30 minutes to complete, and require complex infrastructure. In this study, we determine the sensitivity and specificity of the leukocyte esterase for detection of an infectious process joint in Mexican population. MATERIAL AND METHODS: During November 2015 to April 2016, we obtained synovial fluid from two groups of patients: one with a diagnosis of synovial joint infection with or without implant, and the control group, without infection but with degenerative pathology of the knee...

Bioluminescence is referred to the light emission by a living organism due to a specific biochemical reaction. This interesting feature of the organisms could highly influences behavioral and ecosystem dynamics. Luminescence, mostly observed in marine species, is generally higher in deep-living genera than in benthic or shallow organisms. However, among creatures living in land, fireflies, beetles, springtails and fungi have shown some bioluminescent activities. Classically, the emission of light is catalyzed by luciferase from a substrate...

The aims of this study were to assess the linear relationships between agronomic and nutritional traits and to identify promising traits for indirect selection in early and super-early maturing maize genotypes. Two trials were run in the 2009/2010 agricultural year, each consisting of a randomized block design with three replications. One trial was run on 36 early maturing maize genotypes and the other on 22 super-early maturing genotypes. Six agronomic traits, 11 protein-nutritional traits, and four energetic-nutritional traits were measured...

REVIEW
Graham Finlayson
The concept of addiction is loaded with connotations and is often used for its political as much as its medical utility. The scientific case for 'food addiction' as a clinical phenotype currently rests on its association with generic diagnostic criteria for substance-related disorders being applied to everyday foods and eating-related problems. This has fused the concept of obesity with addiction regardless of whether it fits the definition. The hedonic, or reward, system can account for the ingestion of foods and drugs, confirming that they share neural substrates that differentiate liking and wanting...

Polydopamine is a bioinspired, versatile material that can adhere to bulk and nanoscale surfaces made of disparate materials to improve their physical and chemical properties in many applications. The typical methods to coat polydopamine on the nanoparticle substrates usually take several hours to a day. This work successfully applies a dispersion method to form a controllable, uniform coating on a nanoparticle surface within minutes. Using plasmonic Ag nanoparticles as a substrate, the coating thickness can be monitored using a spectroscopic method based on the extinction peak shifts of the Ag nanoparticles...

Early studies of the bacterial Fe-S cluster assembly system provided structural details for how the scaffold protein and the cysteine desulfurase interact. This work and additional work on the yeast and human systems elucidated a conserved mechanism for sulfur donation but did not provide any conclusive insights into the mechanism for iron delivery from the iron donor, frataxin, to the scaffold. We previously showed that oligomerization is a mechanism by which yeast frataxin (Yfh1) can promote assembly of the core machinery for Fe-S cluster synthesis both in vitro and in cells, in such a manner that the scaffold protein, Isu1, can bind to Yfh1 independent of the presence of the cysteine desulfurase, Nfs1...

The present study aimed at taking the first attempt in validating the measures generated based on the theory of reasoned action (TRA). A total of 211 university students participated in the study, 95 were included in the exploratory factor analysis and 116 were included in the confirmatory factor analysis. The TRA measurements were established with adequate psychometric properties, internal consistency and construct validity. Findings also suggested that attitude towards organ donation has both a cognitive and affective nature, while the subjective norm of the family seems to be important to students' views on organ donation...

RHO GTPases regulate cell migration, cell-cycle progression, and cell survival in response to extracellular stimuli. However, the regulatory effects of RHO GTPases in mesenchymal stromal cells (MSCs) are unclear. Herein, we show that CDC42 acts as an essential factor in regulating cell proliferation and also takes part in lipotoxic effects of palmitate in human umbilical cord Wharton's jelly derived MSCs (hWJ-MSCs). Cultured human bone marrow (hBM-MSCs), adipose tissue (hAD-MSCs), and umbilical cord Wharton's jelly (hWJ-MSCs) derived cells had varying pro-inflammatory cytokine secretion levels and cell death rates when treated by palmitate...

OBJECTIVES: The aims of our study were to determine whether the use of conventional disease-modifying antirheumatic drugs (cDMARDs) or tumor necrosis factor α (TNFα) inhibitors increase the risk of herpes zoster (HZ) in patients with ankylosing spondylitis (AS). METHODS: We searched the South Korean National Health Insurance Service - National Sample Cohort Database for relevant patient records between 2002 and 2013. We evaluated the incidence of HZ by categorizing patients into in three treatment groups: disease-modifying antirheumatic drug (DMARD) nonusers, cDMARD users and TNFα inhibitor users...

We evaluate dark matter (DM) limits from cosmic-ray antiproton observations using the recent precise AMS-02 measurements. We properly take into account cosmic-ray propagation uncertainties, fitting DM and propagation parameters at the same time and marginalizing over the latter. We find a significant indication of a DM signal for DM masses near 80 GeV, with a hadronic annihilation cross section close to the thermal value, ⟨σv⟩≈3×10^{-26}  cm^{3} s^{-1}. Intriguingly, this signal is compatible with the DM interpretation of the Galactic center gamma-ray excess...

By exploiting the similarity between Bloch's theorem for electrons in crystalline solids and the problem of Landau gauge fixing in Yang-Mills theory on a "replicated" lattice, we show that large-volume results can be reproduced by simulations performed on much smaller lattices. This approach, proposed by Zwanziger [Nucl. Phys. B412, 657 (1994)NUPBBO0550-321310.1016/0550-3213(94)90396-4], corresponds to taking the infinite-volume limit for Landau-gauge field configurations in two steps: first for the gauge transformation alone, while keeping the lattice volume finite, and second for the gauge-field configuration itself...

Magnetic fluids (e.g., paramagnetic solutions and ferrofluids) have been increasingly used for label-free separation of non-magnetic particles in microfluidic devices. Their biocompatibility, however, becomes a concern in high-throughput or large-volume applications. One way to potentially resolve this issue is re-suspending the particles that are separated in a magnetic fluid immediately into a biocompatible buffer. We demonstrate herein the proof-of-principle of the first integration of negative magnetophoresis and inertial focusing for a simultaneous separation and washing of non-magnetic particles in co-flowing ferrofluid and water streams...

Background: ETV6/RUNX1 gene fusion is the most frequently seen chromosomal abnormality in childhood acute lymphobastic leukamia (ALL). However, additional genetic changes are known to be required for the development of this type of leukaemia. Therefore, we here aimed to assess the somatic mutational profile of four ALL cases carrying the ETV6/RUNX1 fusion gene using whole-exome sequencing. Methods: DNA was isolated from bone marrow samples using a QIAmp DNA Blood Mini kit and subsequently sequenced using the Illumina MiSeq system...

RATIONALE: Coordination of a metal cation by a nitro group is rare and the interaction between them is usually weak. Examples of complexes in which such an interaction takes place are metal complexes of cyclams containing nitrophenyl or nitrobenzyl substituents. It seemed to be interesting to check if in the complexes of respective crown ether conjugates the interaction can also take place. METHODS: We synthesized the respective conjugates of aza-18-crown-6, namely fluoro-substituted N-nitrophenylaza-18C6 conjugates...

BACKGROUND: There is conflicting evidence about what factors influence outcomes after total knee replacement (TKR). The objective is to identify baseline factors that differentiate patients who achieve both, minimal clinically important difference (MCID) and a patient acceptable symptom state (PASS) in pain and function, measured by WOMAC, after TKR from those who do not attain scores above the cutoff in either of these dimensions. METHODS: One-year prospective multicentre study...

OBJECTIVE: To investigate the clinical characteristics of hypertriglyceridemic acute pancreatitis (HTGAP), and the molecular foundation contributing to the hypertriglyceridemia in this group of patients. METHODS: Clinical data from 329 patients with AP were collected and analyzed. All the patients were divided into 1) HTGAP group (n = 40), with fasting serum triglyceride ≥ 500 mg/dL; and 2) NHTGAP group (n = 289). Next, the targeted next-generation sequencing was applied in 11 HTGAP patients to detect the genetic mutation associated with hypertriglyceridemia that included apolipoprotein A-5 (APOA5), apolipoprotein C-3 (APOC3), apolipoprotein E (APOE), BLK proto-oncogene, lipoprotein lipase (LPL), apolipoprotein C-2 (APOC2), glycosylphosphatidylinositol anchored high density lipoprotein binding protein-1(GPIHBP1), and lipase maturation factor-1(LMF1)...

In Chile, high cost treatments required by selected medical conditions are financed by the State, according to Law 20.850. A bylaw under discussion by the Senate regulates clinical trials, posing complex issues that will endanger local interest in front-line research: 1. The exclusive and mandatory control bestowed to the Institute of Public Health during all stages of the trials and also the surveillance of institutions performing clinical trials, overriding their Clinical Research Review Boards; 2.The 10 year period during which any adverse event is assumed to have been caused by the medication or devise evaluated by the trial, unless the contrary is proven in a judicial process; 3...

Sex work is assumed to have a negative effect on self-esteem, nearly exclusively expressed as low self-worth, due to its social unacceptability and despite the diversity of persons, positions and roles within the sex industry. In this study, we asked a heterogeneous sample of 218 Canadian sex workers delivering services in various venues about how their work affected their sense of self. Using thematic analysis based on a three-dimensional conception of self-esteem - self-worth (viewing oneself in a favourable light), authenticity (being one's true self) and self-efficacy (competency) - we shed light on the relationship between involvement in sex work and self-esteem...
