Knock-down the expression of TaH2B-7D using virus-induced gene silencing reduces wheat drought tolerance

Biol. Res; 52 (), 2019
BACKGROUND: Drought is a major abiotic stress affecting global wheat (Triticum aestivum L.) production. Exploration of drought-tolerant genes is essential for the genetic improvement of drought tolerance in wheat. Previous studies have shown that some histone encoding genes are involved in plant drought ...

Chorioallantoic urothelial tumor avatar. A clinical tool for phenotype-based therapy

Acta cir. bras; 34 (12), 2019
Abstract In the muscle invasive bladder cancer (MIBC) standard of care treatment only patients presenting a major pathological tumor response are more likely to show the established modest 5% absolute survival benefit at 5 years after cisplatin-based neoadjuvant chemotherapy (NAC). To overcome the drawba...

Epigenética y salud: un análisis desde el pensamiento complejo

Rev. salud bosque; 9 (2), 2019
La epigenética es el estudio de los cambios de los genes y su expresión que no generan modificaciones en la secuencia de ADN. Esta implica una serie de mecanismos como la metilación de citosinas del ADN, lo cual se manifiesta en el fenotipo y genera heredabilidad, también llamada heren-cia “suave y...

La singularidad de los maxilares dentro del sistema esquelético
Singularity of the jaws within the skeletal system

En la odontología es frecuente que se describa la peculiaridad de los huesos maxilares en cuanto a la resistencia a las infecciones en comparación con otros huesos de la economía. O que se plantée un desafío cuando es necesario tomar una decisión acerca de aplicar diferentes conductas terapéuticas...

Phylogenetic MLSA and phenotypic analysis identification of three probable novel Pseudomonas species isolated on King George Island, South Shetland, Antarctica

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Antarctica harbors a great diversity of microorganisms, including bacteria, archaea, microalgae and yeasts. The Pseudomonas genus is one of the most diverse and successful bacterial groups described to date, but only eight species isolated from Antarctica have been characterized. Here, we presen...

Inversiones cromosómicas (anomalías estructurales poco frecuentes) asociadas a fenotipo normal, dudoso y patológico

Prensa méd. argent; 104 (10), 2018
Las inversiones son reordenamientos intracromosómicos originados por dos rupturas en un cromosoma seguidas de la reinserción del fragmento rotado en 180º. Dependiendo si involucra o no al centrómero pueden ser pericén tricas o paracéntricas. La incidencia es 0.09 a 0.49/1.000. Las inversiones son r...

Biomarcadores e imunobiológicos na asma

A maioria dos asmáticos é bem controlada com o uso de corticosteroides inalados e beta-agonistas de ação prolongada; contudo, uma proporção de pacientes não responde a esta terapia, e mantém controle limitado da doença. Este grupo experimenta exacerbações frequentes, e requer admissão hospita...
