PARIS--Controversy has erupted over the South African government's decision to withhold the antiviral drug AZT from pregnant women infected with HIV--despite the compound's demonstrated effectiveness at preventing transmission of the virus to offspring.
The scientists found that mice that had been engineered to be genetically incapable of making TNF-alpha did not experience any reduction in taste buds, despite gaining weight, suggesting this compound may be the culprit.
Part of the antimicrobial effect can origin from redox chemistry damaging the bacterial cell wall and can be a reason for the higher efficacy of this compound, despite it is only showing a low value for singlet oxygen generation (Table 1).
An understanding of the function of microcystin remains elusive, despite decades of research on this compound.
Despite its good inhibitory potency, this compound was found to stimulate the MCF-7 and T-47D estrogen-sensitive breast cancer cell lines in vitro, thus greatly reducing its therapeutic potential.
However, despite the significant activity of this compound in preclinical models, in Phase II clinical trial, it only induced a response rate of approximately 10% in a cohort of patients with non-small-cell lung cancer (NSCLC) (Magné et al, 2002; Dancey and Freidlin, 2003).
Another incongruence regarded the high accumulation of this compound in the pulp, despite a low gene activity in the T1 stages.
In the case of resveratrol, binding to monomeric IAPP was not observed in the mass spectrum, despite the compound being present at a 20-fold molar excess over the peptide.
Despite the compound SSR primers targeting the switch points between different microsatellites, most of the sequences amplified were not microsatellites, suggesting that few tandemly arrayed microsatellites exist in the genome of S. latifolia.
Despite the compound SSR primers targeting the switching point of two different microsatellites, most of the amplified sequences were not microsatellites, suggesting that amplified sequences are not the switching points of tandemly arrayed microsatellites.
