V-myb avian myeloblastosis viral oncogene homolog (MYB) transcription factors play important roles in the processes of plant growth, development, and stress responses. In this study, a full-length cDNA sequence of a MYB gene, designated FvMYB1, was isolated from Arizona ash (Fraxinus velutina Torr.) for the first time. Sequence analysis showed that the deduced amino acid sequence of FvMYB1 encoded novel MYB proteins with single DNA binding domains. Based on the R3 domain amino acid sequence, the FvMYB1 was closely related to some proteins whose functions were known. The expression pattern of FvMYB1 in different organs of Arizona ash was analyzed by semiquantitative RT-PCR and real-time PCR (qRT-PCR). Results showed that this gene was widely distributed in all the tested organs and the expression level of FvMYB1 was the highest in stems and the lowest in roots. The gene expression level decreased dramatically in roots under salt treatment (300 mM, 24 h), while no obvious change was observed in stems. Subcellular localization indicated that FvMYB1 was localized in the nucleus. This study will lead to further research in resistance to abiotic stress in Arizona ash.
The aim of this case report is to discuss the recommendations for preoperative evaluation, the technical difficulties experienced in the perioperative period and the ventilation methods used to minimize pulmonary injury in a post-pneumonectomy patient undergoing coronary artery bypass grafting surgery.Bu olgu sunumunun amacı, pnömonektomi sonrası koroner arter baypas greftleme cerrahisi geçiren hastada, preoperatif değerlendirme önerilerini, perioperatif dönemde yaşanan teknik zorlukları ve pulmoner hasarı azaltmak için kullanılan ventilasyon yöntemlerini tartışmaktır.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
