In addition, APAF-1, caspase-3 and -9, and the pro-apoptosis Bcl-2 family member Bim are present in higher concentrations in developing neonatal brain in comparison to adult brain tissue [ 82, 83].
Although most organisms require O2 for survival, as this is the primary substrate for energy production in the cell, physiological O2 concentrations in developing embryos are generally lower (2 9% O2) than in ambient air (21% O2) [ 27].
Constitutive OsASNase expression suggested the accumulation of ammonium; therefore, free ammonium concentration was measured in developing spikelets (Fig. 4a).
The absence of linear growth and concentration of population in developing urban areas means that more accurate statistics on this conversion in the coming years will be greater than the estimated figures.
The thiamine concentration in eggs developing into healthy fry in the study exceeded 1.0 nmol/g, and that in eggs developing into M74-affected fry was below 0.5 nmol/g.
Due to the high levels of taurine concentration in the developing brain, this transmitter has been proposed to act as an endogenous GlyR agonist in the developing cortex (Flint et al., 1998; Yoshida et al., 2004).
Testosterone exerts these influences at times when the testes are active, as evidenced by higher concentrations of testosterone in developing male than in developing female animals.
The risk assessment of selected organochlorine contaminants in breast milk undertaken by the WHO in 1998 showed that DDT concentrations were higher in developing countries and that hexa-chlorobenzene levels were higher in industrialized countries (WHO 1998b).
Pressman, E., Peet, M. M. & Pharr, D. M. The effect of heat stress on tomato pollen characteristics is associated with changes in carbohydrate concentration in the developing anthers.
