α- and β-Cyclodextrins cavity inclusion constants (Ki) were determined for a series of benzaldehydes and acetophenones by using two different methods: Benesi–Hildebrand (BH) UV/vis spectroscopic method and electrochemical current (EC) method, determined by cyclic voltammetry. The values determined in the group of benzaldehydes varied from 322 ± 27 to 5688 ± 317 mol−1 dm3 for UV/vis method, and 342 ± 19 to 7386 ± 142 mol−1 dm3 for EC method. The values determined in the group of acetophenones varied from 2201 ± ...

The gametogenic and endocrine functions of the gonads are both under the integrative control of the central nervous system. The primary regulatory component in this system is the hypothalamic peptide luteinizing hormone-releasing hormone (LHRH), a decapeptide produced by neurons located in the hypothalamic-preoptic region. After synthesis, LHRH is transported to nerve terminals located in the median eminence, where it is released in close proximity to portal capillaries. The decapeptide is then transported ...

The adoption of intelligent systems with Artificial Neural Networks (ANNs) embedded in hardware for real-time applications currently faces a growing demand in fields like the Internet of Things (IoT) and Machine to Machine (M2M). However, the application of ANNs in this type of system poses a significant challenge due to the high computational power required to process its basic operations. This paper aims to show an implementation strategy of a Multilayer Perceptron (MLP) type neural network, in a ...

The ECHO model was developed to expand access to medical care for populations with HCV infection in underserved areas. We aimed to compare HCV treatment outcomes in community-based clinics with the Austral University Hospital (AUH) and to assess improvement in physician knowledge and skills. In October 2015, we established an HCV ECHO clinic at the AUH in Buenos Aires. To evaluate the impact of this programme, we conducted a prospective cohort study comparing treatment for HCV infection at the AUH ...

Computed tomography does not accurately determine which coronary lesions lead to myocardial ischemia and consequently further tests are required to evaluate ischemia induction. The aim of this study was to compare diagnostic accuracy between dual-energy computed tomography and magnetic resonance imaging in the assessment of myocardial perfusion and viability in patients suspected of coronary artery disease.A prospective study was performed in 56 consecutive patients (39 men [69.6%]; mean age [standard ...

The present experiments were designed to determine the effects of different activators of protein kinase C on the secretion of LHRH from median eminence nerve terminals incubated in vitro. The release of prostaglandin E2 (PGE2), a metabolite of arachidonic acid intimately involved in the secretion of LHRH, was also evaluated. Synthetic diacylglycerol [1,2-didecanoylglycerol (DiC10)] significantly enhanced PGE2 release in a concentration-dependent manner. Blockade of phospholipase A2 (PLA2) activity ...

Introduction Systemic sclerosis (SSc) is a rare complex disease characterized by vascular damage, autoimmunity, and extensive skin and internal organs fibrosis. Galectin-3 (Gal-3) is encoded by gene LGALS3 (Lectin, Galactoside-Binding, Soluble, 3; 14q22.3) and it has been reported to play a central role in self-tolerance, inflammation, and fibrosis.Objective To investigate associations among LGALS3 single nucleotide polymorphisms (SNPs) and serum levels Gal-3 and SSc susceptibility and their clinical ...

When the Fundão dam collapsed in Brazil, 50 million m3 of iron ore tailings were released into the Doce river, resulting in the world's largest mining disaster. The contaminated mud was transported 668 km downstream of the Doce river and reached the Atlantic Ocean 17 days after the collapse. Seven months later, there was evidence that the tailings had reached the largest and richest coral reef formation in the South Atlantic Ocean. This study provides the first description of species composition, ...

TGF-β involvement in Chagas disease cardiomyopathy has been clearly demonstrated. The TGF-β signaling pathway is activated in the cardiac tissue of chronic phase patients and is associated with an increase in extracellular matrix protein expression. The aim of this study was to investigate the effect of GW788388, a selective inhibitor of TβR1/ALK5, on cardiac function in an experimental model of chronic Chagas' heart disease. To this end, C57BL/6 mice were infected with Trypanosoma cruzi (102 parasites ...

The hydrogenation reactivity of some classes of organic substrates (α,β-unsaturated ketones, benzaldehydes and acetophenones) was investigated using an electrocatalytic method (undivided cell, nickel sacrificial anode and water/methanol solvent). During the process a nickel deposit is produced on the cathode surface, at the same time that hydrogen is generated by water reduction. Nickel deposit morphologies (catalyst surface) were investigated, taking into account different cathode matrix materials ( ...

Phosphorus loading plays an important role in the occurrence of cyanobacterial blooms and understanding how this nutrient affects the physiology of cyanobacteria is imperative to manage these phenomena. Microcystis aeruginosa and Raphidiopsis raciborskii are cyanobacterial species that form potentially toxic blooms in freshwater ecosystems worldwide. Blooms comprise numerous strains with high trait variability, which can contribute to the widespread distribution of these species. Here, we explored ...

Abstract Preparative electrocatalytic hydrogenation (ECH) of some organic compounds were performed: cyclohexene, 2-cyclohexen-1-one, benzaldehyde, acetophenone, styrene, 1,3-cyclohexadiene, trans – trans -2,4-hexadien-1-ol, citral, linalool and geraniol. H 2 O/MeOH (1:1), NH 4 OAc or NH 4 Cl (0.2 M) were used as solvent and supporting electrolyte. A sacrificial anode of nickel allowed the use of an undivided cell, with a cell voltage varying between 2.3 and 1.3 V, depending on the supporting electrolyte. ...
