several scientists held the hope that the "Maltoni" work would clarify questions about MTBE's carcinogenic potential. Despite the enthusiasm of some scientists for Belpoggi's results, the most cursory examination of the paper reveals critical issues that show the data have been grossly overinterpreted. Rather than predicting a health hazard, the data indicate that rats tolerate enormous daily o...

a Drugs A and B have similar activity. a -l When the effective doses of A and B in combination are located in the area of m+n 1, m> 1, n> 1, they are called par tial antagonism. a -4 When they are located out of the square area, that is, m)1...

Exploitation of drug-drug synergism and allostery could yield superior therapies by capitalizing on the immensely diverse, but highly specific, potential associated with the biological macromolecular landscape. Here we describe a drug-drug synergy mediated by allosteric cross-talk in chromatin, whereby the binding of one drug alters the activity of the second. We found two unrelated drugs, RAPT...

CHEST, 78: 4, OCTOBER, 1980 Only eight cases diagnosed during life as a cyst of the thoracic duct have been reported.’3’59 Although Steinberg and Watson1#{176} reported some cases with a jugular lymph sac at the site of entrance of lymphatic channels into the vein, these cases were thought to be different from the other reported cases. Steinberg and Watson’#{176}concluded that a persistent embr...

Synergism was demonstrated between Sendai virus and Pasteurella pneumotropica in the respiratory tract of mice showing no evidence of previous infection with either agent. Mice aerosol challenged with P. pneumotropica invariably eliminated the viable organism from their lungs within 72 h. In contrast, intrapulmonary killing was delayed in animals previously infected with Sendai virus. Maximum s...

The prevalence of excess body mass (XBM), poor oral health (POH), and stress in a secluded population of aged (≥60 years) Hmong immigrants was surveyed. The findings were related to the prevalence of diabetes in the same population. Diabetes was associated separately with POH (OR 2.4; CL 1.3, 4.2) or with XBM (OR 2.5; CL 1.4, 4.8). The association of diabetes with the combination of XBM and POH...

Joint application of gibberellic acid and indole-3-acetic acid to excised stem sections, terminal cuttings, and decapitated plants of a green dwarf pea results in a markedly synergistic growth response to these hormones. Synergism in green tall pea stem sections is comparatively small, although growth is kinetically indistinguishable from similarly treated dwarf sections.Gibberellin-induced gro...

antimicrobial synergism with streptomycin (SM) against Escherichia coli. On the course of those experiments, a peculiar suppression of SM by a low concentration of hlTC was observed, besides the antibacterial synergism of hlTC with SM. Further, bactericidal actiyity of SM in physiological saline was reduced by addition of hlTC. Time course experiments proyed that the antagonistic effect of hlTC...

Various concepts of interaction are reconsidered in light of a sufficient-component-cause framework. Conditions and statistical tests are derived for the presence of synergism within sufficient causes. The conditions derived are sufficient but not necessary for the presence of synergism. In the context of monotonic effects, the conditions derived are closely related to effect modification on th...

Introduction: Recent epidemiological studies show that episodes due to non-albicans species of Candida (C) such as Candida tropicalis, C. glabrata, C, krusei, C. parapsilosis appear to be increasing in recurrent vulvovaginal candidiasis (RVVC). Increased use of the current antifungal drugs cause drug resistance among Candida species. In order to gain suitable antifungal therapy for this disease...
