Nos últimos anos, vegetais têm sido responsáveis por surtos de enfermidades transmitidas por alimentos (ETA) em diversas regiões do mundo por serem veículos dos mais diferentes micro-organismos patogênicos, entre eles Salmonella spp, Listeria monocytogenes e Escherichia coli produtora de toxina de ...
Background: Cellulose can be converted to ethanol by simultaneous saccharification and fermentation (SSF). The difference between the optimal temperature of cellulase and microbial fermentation, however, has been identified as the critical problem with SSF. In this study, one fungal strain (AnsX1) with h...

A prematuridade ainda é um grande desafio para a Obstetrícia, sendo
considerada a principal causa de morbidade e mortalidade neonatal, com repercussões importantes na infância.
Apesar dos avanços da medicina, ainda falhamos muitas vezes em predizer e prevenir o parto prematuro. Novos
marcadores surg...
Background: New enzymes for biotransformations can be obtained by different approaches including directed mutagenesis and in vitro evolution. These mutants have to be efficiently produced for laboratory research on bioreactions as well as for process development. In the framework of a European ERA-IB pro...

The potential of lipases (E.C.3.1.1.3.) as biocatalysts for the production of fatty acid derivatives for the food and nutraceutical industries, such as flavouring esters, fatty acid esters of antioxidants and structured lipids, is enormous, mainly due to their high regio- and stereo-selectivities, in add...
Enzymes are labile catalysts with reduced half-life time that can be however improved by immobilization and, furthermore, already inactivated catalyst can be recovered totally or partially, therefore allowing the large scale application of enzymes as process catalysts. In recent years a few studies about...
This study evaluated the effect of oral glucosamine and intramuscular injection (IM) of snail mucin on the progression of experimental osteoarthritis (OA) in dogs. Twenty adult mongrels with mean body weight (12.4±1.8 kg) were used. Experimental OA was induced surgically using the groove model. The dogs...
Studies show that some antioxidants are effective in improving male infertility. According to several antioxidant compounds that exist in sesame seed, this study was designed and carried out to the effects of sesame seed diet consumption on adult male rats testis structure and sex hormones. This experime...

Sesamin is a major lignan constituent of sesame seed and considered as a key factor in a number of beneficial effects on human health. Sesame leaves intake improve and increase epididymal spermatocytes reserve in adult male sprague dawley rat. The present study was aimed to investigate the effects of con...
OBJECTIVE: Tillandsia recurvata, also commonly known as Ball Moss, is endemic to Jamaica and some parts of the Caribbean and South America. The plant, despite being reported to be used in folk medicine, had not previously been evaluated for its anti-cancer potential. The aim of this study was to evaluate...
