Gene expression is controlled by the binding of transcription factors (TFs) to regulatory DNA elements to direct the recruitment of cofactors and the transcriptional machinery. The logic of transcriptional regulation by TFs is complex as some TFs can positively or negatively affect one another’s abil...
A new heart position and recipient's weight do not seem to account for the development of a new RBBB delay and decrease in precordial voltage. Other factors, such as mechanical or thermal injury and change in donor-to-recipient age, may be involved. 展开 ...

Viruses initiate infection by penetrating through cell membranes to enter the cytoplasm, which is often a multistep process requiring interactions with cell-surface attachment factors and internalization receptors1,2,3,4,5. Engagement of attachment factors and internalization receptors often dictates host ...
Time Factors (LearningPreschool children learned 4 paired-associate lists, with the same stimuli in all lists, and then were tested for retention of all lists. Two variables were combined factorially: (a) stimulus and response shown in conjunetive relation (control) vs shown in mutual ...
The effect of hormones and growth factors was studied by starving near confluent cells for TSH and insulin in the presence of 0.2% serum (starvation medium) for 72 h. Because of the exceptionally long half-life of NIS (4), to analyze this protein the cells were starved for 7 days. ...
