Objective The addition of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) to endocrine therapy impressively improved the outcome patients with hormone receptor-positive metastatic breast cancer. Despite their great efficacy, not all respond treatment and many them develop acquired resistance. aim this retrospective study was assess role [18F]-FDG PET/CT in predicting PFS OS cancer treated CDK4...
Cytoplasmic male sterility (CMS) systems represent ideal mutants to study the role of mitochondria in pollen development. In sunflower, CMS PET2 also has the potential to become an alternative CMS source for commercial sunflower hybrid breeding. CMS PET2 originates from an interspecific cross of H. petiolaris and H. annuus as CMS PET1, but results in a different CMS mechanism. Southern analyses...
This study is to investigate the value of the metabolic parameters measured by sequential FDG PET/CT in predicting the overall survival of patients with esophageal squamous cell carcinoma (ESCC). A total of 160 patients who were newly diagnosed as ESCC patients and treated with chemoradiotherapy were included in this study. The FDG PET/CT was carried out prior to radiotherapy (PET1), when the c...
The LIM homeodomain transcription factor 1b (Lmx1b) is a key factor in the specification of the serotonergic neurotransmitter phenotype. Here, we explored the capacity of Lmx1b to direct differentiation of mouse embryonic stem (mES) cells into serotonergic neurons. mES cells stably expressing human Lmx1b were generated by lentiviral vector infection. Clones expressing Lmx1b at a low level showe...
استفاده از سیستم نرعقیمی ژنتیکی- سیتوپلاسمی به منظور بهره برداری از پدیده هتروزیس در محصولات زراعی تنها وقتی امکان پذیر است که لاین های اعاده کننده باروری مطلوب موجود باشند. محدودیت ارقام مناسب اعاده کننده باروری، تعداد کم لاین های موثر و سازگار و پایه محدود ژنتیکی آن ها، همواره یکی از مشکلات اساسی تولید برنج هیبرید بوده است. این مطالعه با هدف شناسایی و گزینش بوته های دارای ژن های اعاده کننده ب...
