Background: Zymomonas mobilis, as a novel platform for bio-ethanol production, has been attracted more attention and it is very important to construct vectors for the efficient expression of foreign genes in this bacterium. Results: Three shuttle vectors ( pSUZM 1, pSUZM2 and pSUZM3 ) were first construc...
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgi...
BACKGROUND: Hepcidin, encoding by HAMP gene, is the pivotal regulator of iron metabolism, controlling the systemic absorption and transportation of irons from intracellular stores. Abnormal levels of HAMP expression alter plasma iron parameters and lead to iron metabolism disorders. Therefore,itis animpo...
O câncer de mama é a doença maligna que mais acomete as mulheres no mundo. Apesar dos inúmeros tratamentos, o óbito se deve principalmente à doença metastática que pode se desenvolver a partir do tumor primário. Esta progressão tumoral decorre da dificuldade de se estabelecer um prognóstico ma...
Em Leptospira interrogans algumas proteínas com capacidade de ligação aos componentes de matriz extracelular foram identificadas e, em sua maioria, são fatores de virulência. Phage display é considerada uma técnica poderosa na identificação de novos ligantes, inclusive de moléculas adesinas, im...
Se procesaron 59 muestras de exudado endocervical, de mujeres que asistieron a 2 clínicas de infertilidad y a consulta de regulación menstrual de Ciudad de La Habana, para evaluar el desempeño de un método de detección de Chlamydia trachomatis, basado en la reacción en cadena de la polimerasa (PCR)...
The aim of this work was the construction of a cassette, i.e., a non-replicative molecule formed by linkage of an antibiotic resistance gene and a multiple cloning site. This cassette would allow the cloning and analysis of a wide range of replicons. The aac(6')-lc amikacin gene was isolated and ligated ...
