A method to synthesize cDNA constructs by homology based recombination cloning
(Scientific Research Publishing, 2014-01)We introduce a homology-based recombination approach for generating a cDNA construct. This method depends on amplifying several exon fragments and their fusions by the homology-based recombination. This method provides a ... -
Modulation of gastric mucosal inflammatory responses to Helicobacter pylori by ghrelin: Role of cNOS-dependent IKK-β S-nitrosylation in the regulation of COX-2 activation
(Scientific Research Publishing, 2012-04)Disturbances in nitric oxide synthase (NOS) and cyclooxygenase (COX) isozyme systems, manifested by the excessive NO and prostaglandin (PGE2) generation, are well-recognized features of gastric mucosal inflammatory responses ... -
Molecular characterization and species composition of anopheline vectors of malaria along an altitudinal gradient on the highlands of Mambilla Plateau Northeast, Nigeria
(African Journal of Biological Sciences, 2020-01-01)Diversity of species arises majorly from speciation and this has serious epidemiological implications to disease transmission. The study aimed to determine the species of anopheline vectors of malaria present in five ... -
Molecular cloning and characterization of fruit specific promoter from Cucumis sativus L.
(Scientific Research Publishing, 2012-04)The isolation and characterization of fruit specific promoters are critical for the manipulation of nutritional value and agronomic quality of fruits by genetic engineering and also opened a new era in edible vaccine ... -
Molecular docking investigation for Indonesian H274Y mutant neuraminidase type 1 with neuraminidase inhibitors
(Scientific Research Publishing, 2012-01)The aim of this study is to get insight the interaction between Indonesian H274Y mutant neuraminidase with four inhibitors. Not only to seek preferable inhibitor to be used, but also to investigate the interaction occurred, ... -
Molecular identification of endophytic fungi associated with orchids from Mount Cameroon region
(African Science Publications, 2021-04-05)The orchidaceae (orchid family) is the second largest family of flowering plants after the Asteraceae. Orchids are important in herbal medicine, the food industry, perfumery industry and as ornamentals. They rely on ... -
The molecular regulatory effect of intracerebroventricular thymulin on endotoxin-mediated NF-kB nuclear translocation and activation in vivo
(Scientific Research Publishing, 2013-01)The nuclear factor-kB (NF-kB) is one member of a ubiquitously expressed family of Rel-related transcription factors that serve as critical regulators of proinflammatory genes. The immunomodulatory potential of thymulin and ... -
Molecular surveillance of dengue virus in Bahia State, Brazil
(Scientific Research Publishing, 2012-01)Dengue is an important emerging viruses, posing a threat to one-third of the global human population. In 2002, the introduction of DENV-3 in the state of Bahia produced massive epidemic (about 35,000 cases detected) and ... -
A multi-criteria decision-making approach for comparing sample preservation and DNA extraction methods from swine feces
(Scientific Research Publishing, 2012-04)Molecular microbiological methods, such as competetive PCR, real-time PCR, denaturing gradient gel electrophoresis (DGGE) and large-scale parallel-pyrosequencing, require the extraction of sufficient quantity of high quality ... -
