FEEDBACK, LINEAGES AND SELF-ORGANIZING MORPHOGENESIS.

Feedback, Lineages and Self-Organizing Morphogenesis.

Feedback regulation of cell click here lineage progression plays an important role in tissue size homeostasis, but whether such feedback also plays an important role in tissue morphogenesis has yet to be explored.Here we use mathematical modeling to show that a particular feedback architecture in which both positive and negative diffusible signals

Predictors of maternal HIV acquisition during pregnancy and lactation in sub-Saharan Africa: A systematic review and narrative synthesis.

ObjectivesTo eliminate vertical transmission of HIV, global institutions recommend using a risk-guided approach for HIV prevention services in antenatal and postnatal settings.Identifying predictors of maternal HIV acquisition can inform the development of risk-guided approaches, but individual studies of predictors can have limited power and gener
