Previously, we have shown that flies under-expressing the two mitochondrial peroxiredoxins (Prxs), dPrx3 and dPrx5, display increases in tissue-specific apoptosis and dramatically shortened life span, associated with a redox crisis, manifested as changes in GSH:GSSG and accumulation of protein mixed disulfides. To identify specific pathways responsible for the observed biological effects, we performed a transcriptome analysis. Functional clustering revealed a prominent group enriched for immunity-related genes, including a considerable number of NF-kB-dependent antimicrobial peptides (AMP) that are up-regulated in the Prx double mutant...

Anterior tibial tubercle (ATT) osteotomy facilitates exposure in knee arthroplasty. However, it is not without complications. We have introduced some technical modifications that reduce the surgical aggression by designing a short osteotomy that does not invade the intramedullary canal, and synthesizing it with three cerclage wires with a particular layout that increases the solidity of the system. A retrospective review was performed on the surgical revision of total knee replacement cases intervened in our center that required an ATT osteotomy from February 2014 to February 2015, and who had a minimum clinical follow-up of 12 months...

The drug yielding potential of turmeric (Curcuma longa L.) is largely due to the presence of phyto-constituent 'curcumin.' Curcumin has been found to possess a myriad of therapeutic activities ranging from anti-inflammatory to neuroprotective. Lack of requisite high curcumin containing genotypes and variation in the curcumin content of turmeric at different agro climatic regions are the major stumbling blocks in commercial production of turmeric. Curcumin content of turmeric is greatly influenced by environmental factors...

Commercial inactive dry-yeast based (IDYB) products have been shown to impact positively in different ways on the winemaking process, including sensory enhancement. Despite their relevance little information about physicochemical characteristics of individual IDYB products is available. This study aimed to physicochemically characterize a group of ten commercial IDYB products. Organic, protein and carbohydrate contents by spectrophotometric methods, protein diffusion on cellulose membranes and electrophoretic protein profiles were assessed...

Studies have shown that triggering receptor expressed on myeloid cells-1 (TREM-1) is the mediator and activator of neutrophils and monocytes after stimulation with lipopolysaccharide (LPS), heat-inactivated Gram (-) bacteria, Gram (+) bacteria or fungi. Different studies have measured the expression of TREM-1 in patients with bacterial infections and critical states. The purpose of this study was to evaluate the expression of TREM-1 in circulating maternal leukocytes in premature rupture of the membranes (PRM)...

A polyphasic taxonomic study was carried out on strain EBR-8-1(T) isolated from a biofilm reactor in Korea. The cells of the strain were Gram-stain negative, non-spore-forming, non-motile, and short rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of this strain with Betaproteobacteria, which showed high pairwise sequence similarities with Pusillimonas noertemannii BN9(T) (99.1 %), Pusillimonas soli MJ07(T) (97.3 %), Pusillimonas ginsengisoli DCY25(T) (97.2 %), and Pusillimonas harenae B201(T) (96...

Glucose enters the brain extracellular space from arterial blood and its proper delivery is essential for metabolic activity of brain cells. By using enzyme-based biosensors coupled with high-speed amperometry in freely moving rats, we previously showed that glucose levels in the nucleus accumbens (NAc) display high variability, increasing rapidly following exposure to various arousing stimuli. In this study, the same technology was used to assess NAc glucose fluctuations induced by intravenous heroin. Heroin passively injected at a low dose optimal for maintaining self-administration behavior (100 μg/kg) induces a rapid but moderate glucose rise (~150-200 μM or ~15-25% over resting baseline)...

Here, we have developed an organic photocathode for water reduction to H2 , delivering more than 1 mA cm(-2) at 0 V versus RHE and above 3 mA cm(-2) at -0.5 V versus RHE with moderate stability under neutral pH conditions. The initial competitive reduction of water to H2 and ZnO to metallic Zn is responsible for the dynamic behaviour of both photocurrent and Faradaic efficiency of the device, which reaches 100 % Faradaic efficiency after 90 min operation. In any case, outstanding stable H2 flow of approximately 2 μmol h(-1) is measured over 1 h at 0 V versus RHE and at neutral pH, after equilibrium between the Zn(2+) /Zn(0) concentration in the AZO film is reached...

Host specific adaptations in parasites can lead to the divergence of conspecific populations. However, this divergence can be difficult to measure because morphological changes may not be expressed or because obvious changes may simply reflect phenotypic plasticity. Combining both genetic and phenotypic information can enable a better understanding of the divergence process and help identify the underlying selective forces, particularly in closely-related species groups. Here, we link genetic and morphometric data to understand divergence patterns within the Ornithodoros (Carios) capensis complex, a group of soft ticks (Argasidae) exploiting colonial seabirds across the globe...

The current understanding of the genetic diversity of the phytopathogenic fungus Ustilago maydis is limited. To determine the genetic diversity and structure of U. maydis, 48 fungal isolates were analyzed using mitochondrial simple sequence repeats (SSRs). Tumours (corn smut or 'huitlacoche') were collected from different Mexican states with diverse environmental conditions. Using bioinformatic tools, five microsatellites were identified within intergenic regions of the U. maydis mitochondrial genome. SSRMUM4 was the most polymorphic marker...

Wine is an acidic beverage whose pH (2.9-3.8) is critically important to its organoleptic properties. During degustation, wine interacts with less than 1 mL of mouth saliva whose pH is near 7.0. This is buffered predominantly by the carbonate/bicarbonate pair (pKa 6.1). Not much data is available on whether the buffering capacity of saliva may alter the pH of wine and thus its sensorial properties. In this study both in vitro and in vivo approaches were conducted to measure pH in mixtures of representative red and white wines with human saliva...

Traumatic childhood events can have a significant impact on overall child functioning. Early identification and intervention could offer significant benefits for children's mental health and educational trajectories, but how to effectively identify young children is a challenge. In this paper, we describe screening for exposure to traumatic events and associated symptoms of posttraumatic stress, and examine differences by child gender and grade level. A total of 402 elementary school children in grades 1-5 participated across four elementary schools...

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic, immune disorder mediated largely by food antigens. It shares nonspecific symptoms with gastroesophageal reflux disease (GERD). EoE is rarely reported in Mexico, perhaps due to the racial characteristics of the population or because of insufficient diagnostic suspicion. AIMS: Our aim was to describe a Mexican cohort with EoE and evaluate the usefulness of the clinical history and endoscopy in the EoE diagnosis, in comparison with GERD patients...
