Population growth and composition of the developmental stages of the house dust mite, Dermatophagoides pteronyssinus Trouessart, were studied in the laboratory for 22 wk. The initial mite growth was a sigmoidal increase; during the remaining period of observation, large fluctuations in density were re...
moral principles. Rarely, a step higher to stage 6 is reached, governed by original abstract moral principles such as articulaton of the golden rule. Kohlberg argued that moral development is progressive, without regression to earlier stages....
Quantification of both mRNA and protein levels in brains of individuals with DS from fetal to adult stages have shown that not all trisomic genes are dysregulated or expressed at 1.5-fold (Lockstone et al., 2007; Mao et al., 2005; Mao et al., 2003). Moreover, studies of a single ...
(ART) cycles [1,2,3,4,5], which could explain for the adverse influence of progesterone rise on endometrial receptivity, subsequent embryo-endometrial asynchrony and altered gene expression during the window of implantation [6,7,8]; rather than an inferred impairment on oocyte or embryo quality...

The recent discovery of many genes that regulate brain development is revolutionizing our knowledge of neuroembryology and, moreover, our understanding of how gene defects cause human birth defects. The first 8 weeks of the development of the cerebrum can be subdivided into 23 stages, with early ...
stages, as well as mandibular and cranial covariance structure among individuals. To the best of our knowledge, no rodent study has explored either changes in the magnitude of mandibular size variation within individuals through late ontogeny, or ontogenetic dynamics of mandibular and cranial FA ...
