B2 knockout embryos subjected to salt stress in utero show suppressed renin expression and an abnormal kidney phenotype and develop early postnatal hypertension. Consistently, although basal bradykinin formation is defective tissue kallikrein-null mice have normal blood pressure however suffer from cardiovascular abnormalities. However suggesting a function of kinin signaling during development. [Pg.675]

Development of MMP null mice carrying specific MMP deletions has provided an opportunity to explore the role of MMPs in normal development as well as in such diverse conditions and diseases as skeletal dysplasias, coronary artery and heart disease, arthritis, cancer, and brain disorders. [Pg.748]

The expression of all three PPAR isotypes peaks in the rat central nervous system between days 13.5-18.5 of gestation, and while expression of both PPARa and PPARy decline post-natally, expression of PPARS remains high (except for the retina, where all three isoforms are expressed in the adult rodent). An important role for PPARS in CNS development is underscored by the occurrence of defective myelination in the PPARS-null mouse. [Pg.944]

Epidermal Maturation and Wound Healing. All three PPAR isotypes are expressed during epidermal maturation each isotype has a specific pattern of expression in regard to development and the various layers of the epidermis. An important role for PPARS in the development and/or maintenance of normal skin health is indicated by the presence of defective wound healing in the PPARS-null mouse. [Pg.944]

Several equations have been developed to represent the dependence of activity coefficients on liquid composition. Only those of most use in the design of separation processes will be given. For a detailed discussion of the equations for activity coefficients and their relative merits the reader is referred to the book by Reid et al. (1987), Walas (1984) and Null (1970). [Pg.342]

The data obtained with SERMs are more mixed. Tamoxifen attenuated atheroma development in apoE-null mice, an effect that correlated with changes in the lipoprotein profile and with elevated levels of transforming growth factor-/ (Reckless et al. 1997). The accumulation of cholesterol in atherosclerotic lesions (Bjarnason et al. 1997) in the aorta was limited by... [Pg.229]

In the statistical theory of fluid mixing presented in Chapter 3, well macromixed corresponds to the condition that the scalar means () are independent of position, and well micromixed corresponds to the condition that the scalar variances are null. An equivalent definition can be developed from the residence time distribution discussed below. [Pg.26]

Figure 5.24. A four-environment mixing model can be developed for reactors with three feed streams. In environment 1, the two components of the mixture-fraction vector are null = 0.

Null and Johnson (N4) compared their experimental data with the available models and found a maximum deviation of 377 % with the model developed by Hayworth and Treybal (H5) and 94% with their own model. [Pg.340]
