Drug-resistant bacteria can be effectively eliminated by PDT  and there are no reports of microbes becoming resistant to PDT despite numerous attempts to induce resistance by repeated cycles of semilethal
PDT and microbial regrowth .
Here, we have established that OPN has a protective role in a model of semilethal
WNV infection, especially during acute and postacute time points.
According to the liquid chlorine concentration, the affected areas can be divided into lethal circle (3000 x [10.sup.-6]), semilethal
circle (300 x [10.sup.-6] ~ 3000 x [10.sup.-6]), and injury circle (30 x [10.sup.-6] ~ 300 x [10.sup.-6]) whichwill lead to death, disability, and injury, respectively.
The [Ubx.sup.CPTI000601] line is semilethal
as a homozygote, with some flies surviving to adulthood.
Although no genetic studies have been performed, it seems likely that the green morphs carried a semilethal
Kyphomelic dysplasia: a rare form of semilethal
The most plausible reason for this deficit of variegated-seeded plants could be the semilethal
action of the b1 locus (Tammes, 1928; Shaw et al., 1931; Myers, 1936).
Information about reduced fertility, and perhaps semilethal
effects associated with hairless mutations, were discussed by Sinclair et al.
The nonlethal t haplotypes typically show a reduction in the viability of homozygous t/t embryos ranging between 10% and 90%, and are thus known as the "semilethal
" t haplotypes.
