Câncer de mama e religião: Uma análise qualitativa em um hospital público na cidade de Belo Horizonte, Brasil.

The purpose of this work is to understand possible associations between religious involvement and coping for patients diagnosed with breast cancer. It was conducted 19 individuals in depth interviews with patients undergoing chemotherapy for breast cancer, and applied a survey questionnaire to all of them. The data analysis was made from the content analysis (CA). It was observed that the women interviewed pointed out that not only your healing, but also the possibility of passing the illness experience served to strengthen their religious convictions, and pointed out that their faith played a key role in their healing and in the fact go through process positively disease. Thus, they ended up creating a cycle in which both religious beliefs as their health are seen as strengthened.O objetivo deste trabalho é descrever e compreender possíveis associações entre o envolvimento religioso e o enfrentamento da doença para pacientes diagnosticados com câncer de mama. Foram realizadas 19 entrevistas individuais com pacientes em tratamento quimioterápico contra o câncer de mama, bem como aplicados um questionário padrão a todas as entrevistadas.  A análise das entrevistas foi feita a partir da análise do conteúdo (AC). Observou-se que as mulheres entrevistadas apontaram que não somente a sua cura, mas também a possibilidade de passar pela experiência do adoecimento serviu para fortalecer suas convicções religiosas, bem como apontaram que sua fé teve papel fundamental na sua cura e no fato de passar pelo processo da doença de forma positiva. Desta forma, elas acabaram criando um ciclo em que tanto as convicções religiosas quanto a sua saúde são vistas como fortalecidas

Sugar Versatility—Chemical and Bioprocessing of Many Phytobiomass Polysaccharides Using a Milder Hydrolytic Catalyst: Diluted Thermopressurized Phosphoric Acid

Phytobiomasses, given the qualitative and quantitative dominance of polysaccharides, are a dominant wealth available in nature. Cellulose and hemicelluloses from softwoods, hardwoods and grasses, starch from tubercles and roots, pectins from fruits and gums from some seeds may be explored as such or following acid or alkaline pretreatments as well enzymatic deconstruction, and even simple chemical derivatization toward more added-value products. A general view in the chemistry of these valuable polymers is here broached, following a sharper focus on acid pretreatments for L(h)C—ligno(hemi)cellulosic materials from sugarcane and other feedstocks. Our particular experience using a gentler proton donor but keeping very advantageous aspects for polysaccharide chemo/biotechnological processing—thermopressurized diluted phosphoric acid (oPA)—is presented with a more detailed description as a result of its validity for the hydrolytic deconstruction of hemicelluloses—heteroxylans and heteromannans, cassava starch, dahlia inulin and mixed glucans from microalgae cell walls. The opportunity of NOs—nutraceutical oligosacchrides—generation from these particular glycopolymers is also shortly commented

Acoustically Driven Stark Effect in Transition Metal Dichalcogenide Monolayers

The Stark effect is one of the most efficient mechanisms to manipulate many-body states in nanostructured systems. In mono- and few-layer transition metal dichalcogenides, it has been successfully induced by optical and electric field means. Here, we tune the optical emission energies and dissociate excitonic states in MoSe2 monolayers employing the 220 MHz in-plane piezoelectric field carried by surface acoustic waves. We transfer the monolayers to high dielectric constant piezoelectric substrates, where the neutral exciton binding energy is reduced, allowing us to efficiently quench (above 90%) and red-shift the excitonic optical emissions. A model for the acoustically induced Stark effect yields neutral exciton and trion in-plane polarizabilities of 530 and 630 × 10-5 meV/(kV/cm)2, respectively, which are considerably larger than those reported for monolayers encapsulated in hexagonal boron nitride. Large in-plane polarizabilities are an attractive ingredient to manipulate and modulate multiexciton interactions in two-dimensional semiconductor nanostructures for optoelectronic applications. © 2021 The Authors.

A Highly Pathogenic Strain of Staphylococcus sciuri Caused Fatal Exudative Epidermitis in Piglets

Staphylococcus sciuri are important human pathogens responsible for endocarditis, peritonitis, septic shock, urinary tract infection, pelvic inflammatory disease and wound infections. However, little information is known regarding the pathogenicity of S. sciuri to animals. From the pericardial fluid of a diseased piglet with exudative epidermitis (EE), we isolated a strain of Staphylococcus in pure culture. Surprisingly, this isolate was a member of S. sciuri rather than S. hyicus as identified by its biochemical traits and also by analysis of 23S ribosomal DNA using Internal Transcribed Spacer PCR. In addition, inoculation of newborn piglets with 1×10(10) CFU of the isolate by oral feeding or intra-muscular injection successfully reproduced EE in piglets, which suggested that the oral intake of the pathogen by the animals is one of the major routes of exposure. These unexpected findings prioritized S. sciuri as important zoonotic agents, which may have ramifications for human medicine

Design and development of a multichannel potentiometer for monitoring an electrode array and its application in flow analysis

A versatile potentiometer that works with electrode arrays in flow injection and/or monosegmented flow systems is described. The potentiometer is controlled by a microcomputer that allows individual, sequential multiplexed or random accesses to eight electrodes while employing only one reference electrode. The instrument was demonstrated by monitoring an array of seven flow-through ion-selective electrodes for Ag+ and for three electrodes for Cl-, Ca2+ and K+. The figures of merit of the individual and multiplexed (summed) readings of the electrode array were compared. The absolute standard deviation of the measurements made by summing the potential of two or more electrodes was maintained constant, thus improving the precision of the measurements. This result shows that an attempt to combine the signals of the electrodes to produce a more intense signal in the Hadamard strategy is feasible and accompanied by a proportional improvement in the precision of individual measurements. The preliminary tests suggest that the system can allow for 270 determinations per hour, with a linear range from 1.0 × 10-2 to 1.0 × 10-4 mol l-1 for the three di¡erent analytes. Detection limits were estimated as 3.1 × 10-5, 3.0 × 10-6 and 1.0 × 10-5 mol l-1 for Cl-, Ca2+ and K+, respectively

Correlação entre a aptidão física e os fatores de risco para doenças cardiovasculares em mulheres idosas: Correlation between physical fitness and risk factors for cardiovascular disease in elderly women

Introdução: O envelhecimento promove alterações no sistema cardiovascular que poderá comprometer a aptidão física os idosos. Objetivo: Investigar a correlação entre a aptidão física e os fatores de risco para doenças cardiovasculares em mulheres idosas. Materiais e Métodos: Foram avaliadas 22 mulheres com idades entre 60 e 80 anos participantes do Serviço de Convivência e Fortalecimento de Vínculo do Idoso (SCFVI), do Centro de Referência de AssistÊncia Social (CREAS) da cidade de Eunápolis, Bahia. Foi utilizado o teste de correlação de Pearson para correlacionar a Aptidão Física Geral (ApF) com os Fatores de Risco (FR) e o teste de correlação de Spearman para correlacionar os FR com os domínios da Aptidão Física. Resultados: a média de idade foi de 70 anos (±6), 72,2% viúvas, 59% com ensino fundamental completo e 68,1% com Hipertensão Arterial Sitêmica (HAS) diagnosticada e em tratamento. 45,4% com Índice de Massa Corporal (IMC) classificado com sobrepeso, 68,2% com Circunferência abdominal aumentada substancialmente. A ApF regular foi a classificação mais frequente e sem apresentar correlação com os Fatores de Risco Para Doenças Cardiovasculares avaliados neste estudo. Conclusão: Não foi evidenciado presença de correlação entre os FR’s e o Ínice de Aptidão Física Geral (IAFG), contudo, alguns FR’s se correlacionaram com alguns domínios do IAFG.  Palavras-chave: Doenças Cardiovasculares. Aptidão Física. Geriatria
