These results have been extended to models of several other types of viability selection, such as sexually differential selection (Marks and Ptak 2001), frequency-dependent selection (Trotter and Spencer 2007), and spatially heterogeneous selection (Star et al. 2007a), as well as constant fertility selection (Clark and Feldman 1986).
Reconstitution of the mutant's ability to synthesize heme by adding δ-ALA yielded cultures that were sensitive in the first 2 h to 200 μ M CORM-3, but later recovered to wild-type levels of viability (Fig. 1F).
Ultrasound alone had no effect on cell viability of either type of skin cells (viability of 96±5% for both types of skin cells).
Mice lacking NFAT5 specifically in T cells had no apparent defects compared to wild-type animals in terms of viability and development and, in contrast to previous models of NFAT5 deficiency [18], [24], had normal numbers and proportions of T cells in vivo (Fig. S2).
Whether this type of journalism has commercial viability in future, alongside other forms of community-based news, will partly depend on the extent to which it is valued in communities.
Consequently, several bioelectrochemical factors, such as type of carbon source, cell viability, sensing time and scan rate have been optimized.
Eluates (24 and 48 h) from the materials were applied on the cells and the viability, type of cell death, and morphology were evaluated.
Fresh seeds were (i) dried to various moisture levels, and (ii) stored at −1 and 5 °C to determine loss (or not) of viability and thus type of seed storage behaviour (orthodox, recalcitrant or intermediate).
Thus, the lead compound R2 significantly decreased the viability of cancer cells with wild type p53, without a significant decrease of viability in normal human fibroblasts and in cancer cells with mutant p53.
After 1 h of SDS treatment, the expression of either P55 or P27 partially restored (32%and25%5% loss of viability) the wild type level of resistance to SDS in the mutant strain.
Slices were then either transferred in a 2 mM EDTA solution (pH = 10.9) in ethanol (70% v/v) and immediately frozen in liquid nitrogen, fixed in formalin, cryo-conserved, or stained with fluorescent dyes for identification of cell type and viability.
