Quantitative chemical changes in the human brain during growth

Chemical genetic analyses of quantitative changes in Cdk1 activity during the human cell cycle.

Cyclin-dependent kinase 1 (Cdk1) controls cell proliferation and is inhibited by promising anticancer agents, but its mode of action and the consequences of its inhibition are incompletely understood. Cdk1 promotes S- and M-phases during the cell-cycle but also suppresses endoreduplication, which is associated with polyploidy and genome instability. The complexity of Cdk1 regulation has made it...

QUANTITATIVE AND QUALITATIVE CHANGES IN SHOOT APICAL MERISTEM OF SAFFRON CROCUS DURING THE PERIOD OF GROWTH AND DEVELOPMENT

Quantitative growth and development of human brain.

Dobbing, J., and Sands, J. (1973). Archives of Disease in Childhood, 48, 757. Quantitative growth and development of human brain. One hundred and thirty-nine complete human brains ranging in age from 10 weeks' gestation to 7 postnatal years, together with 9 adult brains, have been analysed in order to describe the human brain growth spurt quantitatively. The three major regions were examined fo...

P-52: Brain-Derived Neurotrophic Factor Promotes The Development of Human Ovarian Early Follicles during Growth In Vitro

Background Cryopreservation of ovarian cortex is increasingly used to preserve fertility before cancer therapy. Recently, studies show that Brain-derived neurotrophic factor (BDNF) may be involved in oocyte maturation. Brain-derived neurotrophic factor (BDNF) is member of neurotrophin family that has anti-apoptotic effects on nervous system. Recent researches show that it also plays key role in...

Changes in chemical composition in male turkeys during growth.

In growing animals, requirements for many nutrients (and energy) are determined by the retention of these nutrients. During growth, this retention changes in an absolute way and also between nutrients and energy, resulting in changing nutrient requirements. The objective of this study was to describe the changes in chemical composition in male growing turkeys. The serial slaughter technique was...
