In flies that have been living in a laboratory for many generations, however, copia proliferates.To show this, Dr Nuzhdin and his colleagues took 30 lines of laboratory-dwelling flies and counted the number of copies of copia in each.
Mr. Rainin secured the rights to sell a line of laboratory pipettes, and through design improvements, built the Pipetman into the dominant brand of pipettes used in laboratories.
We thus conclude that genetic variation found in nine lines likely arose during the course of laboratory breeding and that the founding progenitors of those lines were highly inbred (homozygous).
However, this assumption appears to be poorly justified, given the heterogeneous populations in our classrooms, which needless to say are occupied by humans that bear no resemblance to an inbred line of laboratory-based model organisms.
Several lines of experimental laboratory-based evidence support the concept that p53 is involved in the cellular response to cytotoxic agents and that loss of p53 is associated with resistance to agents such as cisplatin (Righetti et al, 1996; Buttitta et al, 1997; Reles et al, 2001; Siddik, 2003).
Patients were eligible for such regimen for MDR-TB if they failed a retreatment regimen with first line drugs (ahead of laboratory confirmation) or if they were confirmed MDR-TB, while Category 1 failures and smear positive contacts of MDR-TB patients would be tested for DST before start of MDR-TB treatment.
EMDR stimulated various lines of research including laboratory research on the mechanisms involved and on the physiological correlates of EMDR.
Additional lines of evidence, including laboratory mate choice trials, the intermediate length of the sword in X. clemenciae and artificially produced hybrids relative to the two putative close relatives of the parental species, X. maculatus and X. hellerii[ 11], further support the hypothesis of a hybrid origin of X. clemenciae.
Moreover, this "pheno-geographic" pattern at microsatellite loci was further supported in a combined analysis of laboratory lines and specimens collected directly from the wild (see Figure S1, which also incorporates earlier datasets from Tatarenkov et al. [20], [21]).
Our genetic inventory should help to clarify much of this confusion about the clonal identities and genetic relationships of laboratory lines, and thereby help to rejuvenate interest in K. marmoratus as a reliable vertebrate model for experimental research that requires or can capitalize upon "clonal" replicate specimens.
