Physiology and Endocrine Changes Underlying Human Lactogenesis II

Physiology and endocrine changes underlying human lactogenesis II.

Lactogenesis stage II, the onset of copious milk secretion, takes place during the first 4 d postpartum in women and involves a carefully programmed set of changes in milk composition and volume. The evidence is summarized that progesterone withdrawal at parturition provides the trigger for lactogenesis in the presence of high plasma concentrations of prolactin and adequate plasma concentration...

Recognizing and treating delayed or failed lactogenesis II.

Delayed or failed achievement of lactogenesis II--the onset of copious milk volume--occurs as a result of various maternal and/or infant factors. Early recognition of these risk factors is critical for clinicians who interact with breastfeeding women so that intervention and achievement of full or partial breastfeeding can be preserved. This article describes the maternal and infant conditions ...

Biochemical Aspects of Protein Changes in Seed Physiology and Germination

Seed storage proteins are synthesized as sources of carbon, nitrogen and sulfur for the next generation of plants. Reactive oxygen species serve as second messengers for signal transduction; however, molecular targets of oxidant signaling have not been defined. Here, many researchers showes that ligand–receptor mediated signaling promotes reactive oxygen species– dependent protein carbonylation...
