Regulation factors contributing

Many factors contribute to the regulation of stroke volume. Factors discussed in this section include ... 

Dozens of neurotrophic factors regulate the survival of neurons in the central and peripheral nervous systems (Table 1—3). A veritable alphabet soup of neurotrophic factors contributes to the brain broth of chemicals that bathe and nourish nerve cells. Some are related to nerve growth factor (NGF), others to glial cell line—derived neurotrophic factor (GDNF) and still others to various other neurotrophic factors (Table 1—3). Some neurotrophic factors can trigger neurons to commit cellular suicide by making them fall on their apoptotic swords. The brain seems to choose which nerves live or die partially by whether a neurotrophic factor nourishes them... 

Firstly, mammalian sperm regulate ZP3 signal transduction by the process of ca-pacitation, such that uncapacitated sperm exhibit very low rates of spontaneous ac-rosome reaction and do not undergo ZP3-evoked secretion. Several factors contribute to signaling quiescence. 

An additional factor contributing to the proliferation of reports on pesticide contamination of groundwater is ease of pesticide analysis. Pesticides are a predefined analytical target. Federal regulations [2] require the development of defined analytical methods which make identification easier than many other materials, especially natural products. Finally, the current interest in pesticides in groundwater probably focuses efforts which may otherwise have been directed to other chemicals.
