Cyclic Changes in the Cell Surface
Cytochalasin B (CB) shows a marked concentration-dependent inhibition of the incorporation of [(3)H]thymidine into Chinese hamster ovary cells. This inhibition was shown to result from an inhibition of thymidine uptake, not from an inhibition of DNA synthesis. Cells normally acquire the capacity to transport thymidine as they move from the G1 stage of the cell cycle into the S phase. If CB is a...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Cisplatin Induce Changes of Cell Surface Glycoconjugates in Germinal Epithelium of Seminiferous Tubules
Introduction: Cisplatin is a platinum-based drug widely used for the treatment of different cancers. Cell surface glycoconjugates play an important role in cell-cell interactions. The present investigation was carried out to study the toxic effects of double dose injection of cisplatin on cell surface glycoconjugates in rat as an experimental model. Methods: In this experimental study, 45 adul...
متن کاملChanges in ground surface temperature in the city of Halle and its relationship with changes in the NDVI index
Changes in ground surface temperature in the city of Halle and its relationship with changes in the NDVI index abstract The temperature of the urban environment is one of the parameters that citizens are in contact with at any moment. Studies show that the global temperature is constantly increasing due to environmental changes. One of these parameters that affect the increase in temperature;...
متن کاملTemporal changes in embryonal cell surface recognition.
Plasma membranes have been prepared from optic tectum and neural retina of chick embryos. These membranes specifically inhibit the aggregation of homotypic cells. Plasma membranes prepared from each of these regions obtained from chick embryos at 7,8, and 9 days of development show specificity for homotypic cells of the same age and cross-react weakly with homotypic cells of different ages. Thu...
