O fenol como agente neurolítico no tratamento da espasticidade focal e multifocal

Acta fisiátrica; 26 (1), 2019
A síndrome piramidal ocorre nas lesões do sistema nervoso central que afetam as vias corticoespinhais e são definidas pela tríade de fraqueza muscular, aumento dos reflexos miotáticos e espasticidade, que é definida pelo aumento involuntário da resistência ao movimento passivo cuja intensidade va...

Pesquisa de opinião sobre eficácia, custos e cicatrização de procedimentos de resurfacing para rugas estáticas faciais

Foi realizada uma pesquisa de opinião entre especialistas em “resurfacing” cutâneo com a finalidade de compararem-se custos e benefícios entre as técnicas de laser de CO2 totalmente ablativo, lasers fracionados ablativos, lasers fracionados não ablativos, radiofrequência fracionada ablativa, mi...

Key microbial populations involved in anaerobic degradation of phenol and p-cresol using different inocula

Background: Anaerobic digestion is an alternative bioprocess used to treat effluents containing toxic compounds such as phenol and p-cresol. Selection of an adequate sludge as inoculum containing an adapted microbial consortium is a relevant factor to improve the removal of these pollutants. The objectiv...

Antioxidant activity of ethyl acetate and methanolic extracts of two marine algae, Nannochloropsis oculata and Gracilaria gracilis - an in vitro assay

ABSTRACT The aim of this study was to evaluate the antioxidant activity of ethyl acetate and methanolic extracts of two marine algae, Nannochloropsis oculata and Gracilaria gracilis. The extracts were assayed for total phenol and flavonoid content, DPPH free radical scavenging capacity, nitric oxide acti...

Phenol degradation and genotypic analysis of dioxygenase genes in bacteria isolated from sediments

Braz. j. microbiol; 48 (2), 2017
Abstract The aerobic degradation of aromatic compounds by bacteria is performed by dioxygenases. To show some characteristic patterns of the dioxygenase genotype and its degradation specificities, twenty-nine gram-negative bacterial cultures were obtained from sediment contaminated with phenolic compound...

Proteomic analysis of latex from Jatropha curcas L. stems and comparison of two classic proteomic sample isolation methods: the phenol extraction and the TCA/acetone extraction

Background: Jatropha curcas is a wide-spreading latex-rich biodiesel plant with high oil content in seeds that have always been under intense studies. However, studies are lacking on the latex component that is considered rich in proteins with potentially important physiological functions and secondary m...

In vitro antioxidant activity and qualitative phytochemical analysis of two Vismia (Hypericaceae) species collected in Los Andes, Venezuela

Rev. biol. trop; 64 (4), 2016
Abstract:Vismia genus is distributed mainly in tropical and subtropical regions of Central, South America and some areas of Africa. According to previous investigations, antioxidant potential of Vismia species might be related to anthrones, anthraquinones, flavonoids and phenol derivatives biosynthesized...

Comparative evaluation of Ziehl Neelsen staining and knowledge, attitudes and practices of laboratory personnel in relation to Ziehl Nielsen

West Indian med. j; 63 (1), 2014
OBJECTIVE: To describe laboratory personnel's attitude and practices toward phenol exposure during Ziehl Neelsen (ZN) acid fast staining method and to evaluate the feasibility of an alternate modified Kinyoun cold (MKC) stain. METHOD: A total of 187 sputum samples were collected from suspected tuberculos...

Estudo dos mecanismos de ação da hidroquinona e fenol sobre o recrutamento leucocitário em respostas inflamatórias

Hidroquinona (HQ) é um dos metabólitos do benzeno responsáveis pelos efeitos tóxicos da exposição ao solvente, além de ser componente da dieta, medicamentos, cigarro e poluente do meio ambiente. Considerando a imunotoxicidade desta substância, o grupo de pesquisa do laboratório investiga o papel...
