Electrochemical Synthesis of d,l-Homocysteine Thiolactone Hydrochloride in a Batch Continuous Recirculation Reactor Equipped with Carbon Felt Cathode…

2007

The electrochemical reduction of D,L-homocystine hydrochloride to the corresponding cysteine was performed in a batch continuous recirculation reaction system that was equipped with a FM01-LC electrochemical reactor. Electrolyses were performed under amperostatic conditions, using carbon felt cathodes and DSA anodes divided by Nafion 324 cationic membranes. A simple reactor mathematical model was used to assess the effect of operative parameters (the initial substrate concentration, the reaction temperature, the current density, and the linear velocity of the catholyte) on the performances of the process, with the objective of determining the optimized conditions to perform the electrosynth…

Glucose oxidase as a biocatalytic enzyme-based bio-fuel cell using Nafion membrane limiting crossover

2013

A novel combination for an Enzyme-based Biofuel cell included a Nafion membrane as an ion transporter that maintained a working cell charge and inhibited membrane degradation. The prototype cell chamber used oxygen (O2) in the cathode cell and glucose in the anode. The Nafion membrane stability studied here was evidently in the region of 0% loss of conductivity as the charge was constant and increased after the addition of glucose. The prototype cell chamber used NaCl in the cathode cell and glucose oxidase (GOx) in the anodic chamber was successfully studied for membrane stability showed in this study no evidence of poisoning from membrane leakage in a controlled pH environment. There was …

Paradoxical effect of increased diastolic Ca(2+) release and decreased sinoatrial node activity in a mouse model of catecholaminergic polymorphic ven…

2012

Background— Catecholaminergic polymorphic ventricular tachycardia is characterized by stress-triggered syncope and sudden death. Patients with catecholaminergic polymorphic ventricular tachycardia manifest sinoatrial node (SAN) dysfunction, the mechanisms of which remain unexplored. Methods and Results— We investigated SAN [Ca 2+ ] i handling in mice carrying the catecholaminergic polymorphic ventricular tachycardia–linked mutation of ryanodine receptor (RyR2 R4496C ) and their wild-type (WT) littermates. In vivo telemetric recordings showed impaired SAN automaticity in RyR2 R4496C mice after isoproterenol injection, analogous to what was observed in catecholaminergic polymorphic ventricul…

Clostridium baratii bacteremia associated with Kawasaki syndrome. First case report

2007

We experienced a case of a 3-year-old boy who presented signs and symptoms of Kawasaki syndrome. Two blood culture sets were processed by the hospital microbiology laboratory using a standard blood culturing system. The anaerobic bottles gave a positive result at day 3 after inoculation. The biochemical profiles produced by the RapID ANA II System showed that the organism was Clostridium baratii with a probability of 99%. Our case highlights the importance of C. baratii as a potential human pathogen and reports the associations with manifestations, which, to our knowledge, have not been previously described concomitantly with a clostridial infection.

Molecular Classification of N-Aryloxazolidinone-5-carboxamides as Human Immunodeficiency Virus Protease Inhibitors

2015

Algorithms for classification and taxonomy are proposed in this chapter based information entropy (IE) and its production. The 38  N- aryloxazolidinone-5-carboxamides (NCAs), for human immunodeficiency virus (HIV) protease (PR) inhibition, are classified using seven characteristic chemical properties of different moieties: R 1/2 , R 3–6 on different phenyls and R 7 . Many classification algorithms are based on IE. When applying some procedures to moderate-sized sets, excessive number of results appear compatible with the data and suffer combinatorial explosion. However, after the equipartition conjecture (EC), one has a selection criterion among different variants that results from classifi…

Table of periodic properties of human immunodeficiency virus inhibitors

2010

Classification algorithms are proposed based on information entropy. The feasibility of mixing a given human immunodeficiency virus (HIV) inhibitor with dissimilar ones is studied. The 31 inhibitors are classified by their structural chemical properties. Many classification algorithms are based on information entropy. An excessive number of results appear compatible with the data and suffer combinatorial explosion. However, after the equipartition conjecture one has a selection criterion. According to this conjecture, the best configuration is that in which entropy production is most uniformly distributed. The structural elements of an inhibitor can be ranked according to their inhibitory a…

ADDITIVITY FROM MULTIPLE PRIMES IN IDENTIFYING BACKWARD WRITTEN WORDS

1988

Activational theories of memory assume that activation from several sources adds up to an intersecting node. We tested this idea in one experiment where we kept constant the number of primes presented and we manipulated the number of different primes related to the target, the number of presentations of the same prime, or the same target, presented as a prime. We used a task in which the target was always a word, which appeared written backward and had to be identified. We found a strong effect of target repetition and diminished priming in the condition in which the target was repeated. We obtained additivity (greater activation) mainly in the condition in which we presented several diffe…

Citocentrifugación como un método adicional para estudiar celomitos de equinodermos: un enfoque comparativo que combina células vivas, preparaciones …

2021

Abstract Introduction: Echinoderm coelomocytes have traditionally been investigated through a morphological approach using light microscopy, which relies on the idea of constant cell shape as a stable character. However, this can be affected by biotic or abiotic conditions. Objective: To analyze if the consistency in cell morphology offered by the cytocentrifugation method, might be used as a convenient tool to study echinoderm coelomocytes. Methods: Cells of Echinaster (Othilia) brasiliensis (Asteroidea), Holothuria (Holothuria) tubulosa (Holothuroidea), Eucidaris tribuloides, Arbacia lixula, Lytechinus variegatus, and Echinometra lucunter (Echinoidea) were spread on microscope slides by c…

A Guaranteed performance of a green data center based on the contribution of vital nodes

2016

International audience; In order to satisfy the need for the critical computing resources, many data center architectures proposed to house a huge number of network devices. These devices are used to achieve the highest performance in case of full utilization of the network. However, the peak capacity of the network is rarely reached. Consequently, many devices are set into idle state and cause a huge energy waste leading to a non-proportionality between the network load and the energy consumed. In this paper, we propose a power-aware routing algorithm that saves energy consumption with a negligible trade-off on the performance of the network. The idea is to keep active only the source and …
