Valorisation of Wasted Immature Tomato to Innovative Fermented Functional Foods.

In this study, the lactic fermentation of immature tomatoes as a tool for food ingredient production was evaluated as a circular economy-oriented alternative for valorising industrial tomatoes that are unsuitable for processing and which have wasted away in large quantities in the field. Two lactic acid bacteria (LAB) were assessed as starter cultures in an immature tomato pulp fermentation to produce functional food ingredients with probiotic potential. The first trial evaluated the probiotic character of (LAB97, isolated from immature tomato microbiota) and (C1090, from the INIAV collection) through in vitro gastrointestinal digestion simulation.

Objectives: To analyze the immediate effects of voiced high-frequency oscillation (VHFO) and Lax Vox technique on vocal quality and self-reported intensity of vocal and laryngeal symptoms in individuals with behavioral dysphonia.

Methods: This experimental, prospective, randomized cross-over study, investigated thirty adults (15 women and 15 men) with behavioral dysphonia (vocal complaints, altered voice on auditory-perceptual evaluation, vocal nodules or mucosal thickening, and incomplete glottic closure). The outcome variables analyzed were auditory-perceptual analysis, acoustic analysis (voice quality characteristics), and self-reported intensities of vocal and laryngeal symptoms.

High Frequency of Extended-Spectrum Beta-Lactamase-Producing Nosocomial Strains Isolated from a Teaching Hospital in Brazil.

The aim of this study was to investigate the frequency, antimicrobial sensitivity profile, and genetic characteristics of nosocomial strains of extended-spectrum β-lactamase (ESBL)-producing isolated from inpatients at a teaching hospital in Brazil.

Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) mass spectrometry was used to confirm the identity of the species and genotyping of ESBL-producing was performed by pulsed-field gel electrophoresis (PFGE).

A high mortality rate associated with multidrug-resistant Acinetobacter baumannii ST79 and ST25 carrying OXA-23 in a Brazilian intensive care unit.

The global spread of carbapenem-resistant Acinetobacter baumannii (A. baumannii) strains has restricted the therapeutic options available to treat infections due to this pathogen. Understanding the prevalence of such infections and the underlying genetic mechanisms of resistance may help in the implementation of adequate measures to control and prevent acquisition of nosocomial infections, especially in an intensive care unit setting.

Detection and analysis of different interactions between resistance mechanisms and carbapenems in clinical isolates of Klebsiella pneumoniae.

Carbapenems are considered last-line agents for the treatment of serious infections caused by Klebsiella pneumoniae, and this microorganism may exhibit resistance to β-lactam antibiotics due to different mechanisms of resistance. We evaluated 27 isolates of K. pneumoniae resistant to carbapenems recovered from inpatients at the University Hospital of Santa Maria-RS from July 2013 to August 2014.

In vitro susceptibility of Burkholderia cepacia complex isolates: Comparison of disk diffusion, Etest®, agar dilution, and broth microdilution methods.

Broth microdilution, agar dilution, Etest® and disk diffusion techniques were compared to evaluate the susceptibility profile of 82 Bcc clinical isolates against six antimicrobials as recommended by CLSI. Broth microdilution was considered the "gold standard" method. The regression analysis was applied to determine the essential (EA) and categorical (CA) agreement rates.

Objective: To establish whether the mutation in the Immp2L gene induces renal fibrosis and whether aging exacerbates renal morphology in mice.

Methods: Female mutant mice with mutation in the inner mitochondrial membrane peptidase 2-like protein at 3 and 18 months of age were used. Renal fibrosis was analyzed using classic fibrosis score, Masson's trichrome staining, and analysis of profibrotic markers using real time polymerase chain reaction (superoxide dismutase 1, metalloproteinase-9, erythropoietin, transforming growth factor beta), and immunostaining (fibroblasts and Type IV collagen).

Phylogeography of the tree Hymenaea stigonocarpa (Fabaceae: Caesalpinioideae) and the influence of quaternary climate changes in the Brazilian cerrado.

Background And Aims: Hymenaea stigonocarpa (Fabaceae: Caesalpinioideae) is an endemic tree from the Brazilian cerrado (savanna vegetation), a biome classified as a hotspot for conservation priority. This study investigates the phylogeographic structure of H. stigonocarpa, in order to understand the processes that have led to its current spatial genetic pattern.

Central H1 and H2 receptor participation in the control of water and salt intake in rats.

The aim of the present study was to evaluate the participation of brain H1 and H2 histaminergic receptors on water and salt intake induced by water deprivation (24 h), furosemide-induced sodium depletion and central angiotensinergic pharmacological stimulation in rats. Third ventricle injections of the H1 and H2 receptor antagonists, mepyramine (50, 100, 200 and 400 nmol) and cimetidine (100, 200 and 400 nmol), were unable to modify water intake induced by water deprivation and sodium depletion. Salt intake elicited by water deprivation and sodium depletion was reduced by the central administration of mepyramine, while intracerebroventricular administration of cimetidine had no effect.
