The molecular diversity analysis of Auricularia auricula-judae in China by nuclear ribosomal DNA intergenic spacer

Electron. j. biotechnol; 17 (1), 2014
Background: For the crossbreeding of Auricularia auricula-judae, selecting the appropriated parents in hybridization is very important. However, the classification and diversity analysis of A. auricula-judae has been equivocal, due to the similarity of the fruiting body morphology and its susceptibility ...

Análisis de mutaciones en los genes PINK1 Y PARKIN en pacientes colombianos con enfermedad de Parkinson

NOVA publ. cient; 12 (21), 2014
La enfermedad de Parkinson es un desorden neurodegenerativo complejo, caracterizado por la pérdida progresiva de las neuronas dopaminérgicas de la sustancia nigra pars compacta. Factores tanto ambientales como genéticos se ha determinado que contribuyen a su desarrollo. Mutaciones en los genes PINK1 y...

A retrotransposição de mRNAs como fator de variabilidade genética no genoma humano e de outros primatas

Duplicação genica é uma das principais forças levando a evolução dos genomas eucarioto. O impacto de duplicações gênicas/genômicas vem sendo investigado a muito tempo em humanos e outros primatas. Um segundo mecanismo de duplicação gênica, a retrotransposição baseada em RNA maduros, vem se...

Assessment of analytical techniques for characterization of crystalline clopidogrel forms in patent applications

Braz. j. pharm. sci; 50 (2), 2014
The aim of this study was to evaluate two important aspects of patent applications of crystalline forms of drugs: (i) the physicochemical characterization of the crystalline forms; and (ii) the procedure for preparing crystals of the blockbuster drug clopidogrel. To this end, searches were conducted usin...

Thermoanalytical studies of carbamazepine: hydration/dehydration, thermal decomposition, and solid phase transitions

Braz. j. pharm. sci; 50 (4), 2014
Carbamazepine (CBZ), a widely used anticonvulsant drug, can crystallize and exhibits four polymorphic forms and one dihydrate. Anhydrous CBZ can spontaneously absorb water and convert to the hydrate form whose different crystallinity leads to lower biological activity. The present study was concerned to ...

Genetic polymorphisms and asthma: findings from a case - control study in the Madeira island population

Biol. Res; 47 (), 2014
BACKGROUND: Asthma is a complex disease influenced by multiple genetic and environmental factors. While Madeira has the highest prevalence of asthma in Portugal (14.6%), the effect of both genetic and environmental factors in this population has never been assessed. We categorized 98 asthma patients acco...

Analysis of genetic and epigenetic variation in in vitro propagated potato somatic hybrid by AFLP and MSAP marker

Electron. j. biotechnol; 16 (6), 2013
Background: Genetic and epigenetic changes (DNA methylation) were examined in the tissue-culture propagated interspecific potato somatic hybrids between dihaploid Solanum tuberosum and S. pinnatisectum. Amplified fragment length polymorphism (AFLP) and methylation-sensitive amplified polymorphism (MSAP) ...

Genetic diversity among native varieties and commercial cultivars of Solanum tuberosum ssp. tuberosum L. present in Chile

Electron. j. biotechnol; 16 (6), 2013
Background: The object of this work was to determine the genetic and allelic diversity of Solanum species present in Chile, assessing allelic distribution among native varieties and commercial cultivars of Solanum tuberosum ssp. tuberosum L., using microsatellite markers. Results: A high level of allelic...

Greenhouse evaluation on the performance of heat tolerant transgenic broccoli and genetic diversity analysis using inter simple sequence repeat (ISSR) markers

Electron. j. biotechnol; 16 (5), 2013
Background: Broccoli, Brassica oleracea subsp. italica is one of the many valuable Brassica species which is still less cultured under in vitro condition. Heat tolerant transgenic and non-transgenic broccoli cv. Green Marvel plantlets with well-developed root system obtained through in vitro culture were...
