Actividad de fosfolipasas y proteasas en aislamientos de especies de Candida colonizadoras y causantes de vulvovaginitis en mujeres gestantes

Biomédica (Bogotá); 43 (Supl. 1), 2023
Introducción. Las proteasas y las fosfolipasas son factores de virulencia de Candida spp. que cumplen un papel importante en la invasión de los tejidos. Entre los factores relacionados con el huésped, se encuentran algunos asociados con las características ambientales y otros con la colonización. Ob...

Cushing disease due to a somatic USP8 mutation in a patient with evolving pituitary hormone deficiencies due to a germline GH1 splicing variant

SUMMARY We present the unique case of an adult Brazilian woman with severe short stature due to growth hormone deficiency with a heterozygous G to T substitution in the donor splice site of intron 3 of the growth hormone 1 (GH1) gene (c.291+1G>T). In this autosomal dominant form of growth hormone defi...

Production of extracellular alkaline protease by new halotolerant alkaliphilic Bacillus sp. NPST-AK15 isolated from hyper saline soda lakes

Electron. j. biotechnol; 18 (3), 2015
Background Alkaline proteases are among the most important classes of industrial hydrolytic enzymes. The industrial demand for alkaline proteases with favorable properties continues to enhance the search for new enzymes. The present study focused on isolation of new alkaline producing alkaliphilic bacter...

Purification and characterization of an aspartic protease from the Rhizopus oryzae protease extract, Peptidase R

Electron. j. biotechnol; 17 (2), 2014
Background Aspartic proteases are a subfamily of endopeptidases that are useful in a variety of applications, especially in the food processing industry. Here we describe a novel aspartic protease that was purified from Peptidase R, a commercial protease preparation derived from Rhizopus oryzae. Results ...

Effect of laundry detergent formulation on the performance of alkaline phytoproteases

Electron. j. biotechnol; 16 (3), 2013
Background: Proteases constitute the largest product segment in the global industrial enzymes market; they are used in food, pharmaceutical, leather, textile, wood and detergent industries. Alkaline proteases improve the cleaning efficiency of detergents and represent one of the most successful applicati...

A participação das metaloproteinases da matriz nos processos fisiopatológicos da cavidade bucal
The participation of matrix metalloproteinases in the physiopathological processes of the oral cavity

Rev. odontol. UNESP; 35 (4), 2006
Metaloproteinases da Matriz (MMPs) são um importante grupo de enzimas proteolíticas zinco-dependentes responsáveis pela degradação de matriz extracelular e membranas basais. As enzimas são secretadas em uma forma latente e se tornam ativadas no ambiente pericelular, sendo relacionadas a processos f...

Vaginose bacteriana
Bacterial vaginosis

Femina; 32 (8), 2004
A vaginose bacteriana VB é caracterizada pela substituição da flora vaginal, na qual há predomínio de lactobacilos, por complexa e abundante flora de bactérias anaeróbicas.Leucorréia abundante e fétida é o sintoma típico dessa infecção.Tais bactérias seriam capazes de produzir enzimas, prot...
