Drought-induced stress is the main limiting factor that affects growth and development in plants. In this study, the effect of exogenous application of salicylic acid (SA) on drought tolerance in basil was investigated. The analysis showed that application of SA under drought stress had significant effects on physiological and biochemical parameters, such as photosynthetic pigments content, total phenolics, flavonoids, flavanols and protein content and peroxidise activity, but had no significant effects on the morphological parameters, such as stem length, length and areaof leaves . In drought conditions, total phenolics and peroxidase activity reduced significantly, but all photosynthetic pigments, total flavonoids, flavanols and proteins increased significantly. Application of SA displayed some alleviating effects against drought induced stress through increase of plant growth, total flavonoids content and peroxidase activity

Nasopharyngeal carcinoma (NPC) treatment is mainly based on clinical staging. We hypothesize that better understanding of the molecular heterogeneity of NPC can aid in better treatment decisions. Therefore, the purpose of this study was to present our exploration of cancer gene copy‐number alterations (CNAs) of Epstein‐Barr virus (EBV)‐positive and EBV‐negative NPC.

O objetivo da pesquisa foi identificar e caracterizar as práticas de lazer durante a maturidade de idosas. Utilizou-se à abordagem qualitativa, com opção metodológica pela História de Vida. A população participante da pesquisa foi de 9 (nove) idosas com idade acima de 80 (oitenta) anos, participantes do grupo de convivência “Pioneiras de Rondônia". Realizaram-se entrevistas do tipo aberta; e para  registro, o recurso de gravação. Para identificar as depoentes, lhes foram atribuídos nomes indígenas. As práticas de lazer das idosas durante a maturidade eram bastante limitadas. Esta restrição, por um lado, se devia a precariedade na infraestrutura destinada ao lazer na cidade de Porto Velho que oferecia escassez em quantidade e qualidade. O  baixo poder aquisitivo e a dedicação de grande parte do tempo ao trabalho dentro e fora do lar, eram fatores  em: se aproximam.adas..ho].ida s prpouca ou nenhuma importt . dadefaotoreso; e por outro lado  que também limitavam o  lazer.

Codon usage is considered as a modulator of gene expression, due to high correlation between codon usage, tRNA abundance and the level of gene expression. Adaptability is primarily manifested at gene level therefore mtDNA gene expression analysis may indicate trends toward the development of adaptive traits for specific environmental conditions. Moreover, modified gene expression patterns may result from such adaptations. Due to their sensitivity to environmental disturbances, great functional importance and accessibility ants (Family: Formicidae Latreille, 1802) are excellent model organisms for  molecular and bioinformatics genome analysis. This in silico simulation is based on the comparison of codon usage bias and the level of gene expression of currently available mitochondrial protein-coding genes of ant species that were sampled at quarry Ribnica (Kakanj, Bosnia and Herzegovina). MILC and MELP algorithms were used forcodon usage bias analysis and mitochondrial gene expression prediction, respectively. The analysis included four mtDNA protein-coding genes from eight selected species of ants totaling in 32 protein sequences. The results of codon usage analysis indicated no statistically significant differences in codon usage bias, as well as relative frequencies of the gene expression level.  The next step should be directed to molecular ecology studies, even using whole genome measures of gene expression (RNA-seq; transcriptomics) to capture molecular response to environmental challenges.
