Another two-generational teratogenicity study in mice, florfenicol (40, 120, or 400 mg/kg by gavage) on days 6-15 of gestation showed signs of embryo lethality at the high dose.
G1 accumulation occurred in a dose-dependent manner in these 4 cell lines, with a slight decrease at a concentration of 40 μM MF corresponding to an increase in hypodiploid DNA content, indicating cellular lethality at this high concentration of the steroid (see below; Figure 3).
Thirteen of the alleles we have characterized here are potentially fast-acting, and we could not make a determination on six others because of either 1) weak or low penetrance defects or, 2) high lethality at the permissive temperature.
As summarized in Table 5, mibefradil (T-type) showed the highest lethal activity (36.8±5.7% lethality at 1 mM) followed by verapamil (L-type, 24.3±5.1% lethality).
Because low CSF levels of 5HIAA have been correlated with high levels of lethality at the suicide attempt [ 1], a sub-sample (MDS high) of triplets was selected, wherein all probands had suffered high medical damage.
The response surfaces showed a synergistic effect of temperature and pressure for both species, resulting in the highest cell lethality at 300 MPa and at either 45 °C or −5 °C and lowest cell lethality when the temperature was closer to room temperature.
In particular, we have shown that the lethality that IPA displays at high doses can be partially overcome if the PERK pathway is inactivated using a selective PERK inhibitor, GSK, increasing the EC50 with which IPA drives cells into apoptosis by about an order of magnitude.
Indeed, HEK293T cells with higher expression of Magmas showed better viability at higher concentrations of NaAsO2 as compared with control cells that showed enhanced lethality with the increase in the oxidative insult.
In particular, at higher concentrations they are responsible for sepsis and the septic shock syndrome associated with high lethality.
