In this paper, the quantitative structure-activity relationship predictive models (QSAR) are presented: prediction model for some of main components cannabis sativa, acute toxicity LD50 (n=45, r2=0.917, q2=0.902), chronic LOAEL (n=35, r2=0.911, q2=0.868), NOAEL(n=22, r2=0.964, q2=0.937), LOEL (n=26, q2=0.863) and NOEL (n=25, r2=0.867, q2=0.802), in addition to carcinogenicity mutagenicity effec...

Many details surrounding the origins of the peoples of Oceania remain to be resolved, and as a step towards this we report seven new complete mitochondrial genomes from the Q2a haplogroup, from Papua New Guinea, Fiji and Kiribati. This brings the total to eleven Q2 genomes now available. The Q haplogroup (that includes Q2) is an old and diverse lineage in Near Oceania, and is reasonably common;...

We present a new expression of the polynomial Hamiltonian of the Garnier system in two variables. 1. Main results The Garnier system in two variables is equivalent to the rational Hamiltonian system given by (see [18], cf. [3]) dq1 = ∂H1 ∂p1 dt + ∂H2 ∂p1 ds, dp1 = − ∂H1 ∂q1 dt− ∂H2 ∂q1 ds, dq2 = ∂H1 ∂p2 dt + ∂H2 ∂p2 ds, dp2 = − ∂H1 ∂q2 dt− ∂H2 ∂q2 ds, H1 = − q1(q1 − 1)(q1 − t)(q1 − s)(q2 − t) (...

BACKGROUND A graded but nonlinear relationship exists between fitness and mortality, with the greatest mortality differences occurring between the least-fit (first, Q1) and the next-least-fit (second, Q2) quintiles of fitness. The purpose of this study was to compare clinical characteristics, exercise test responses, and physical activity (PA) patterns in Q1 versus Q2 in patients with cardiovas...

JNJ-Q2 is a novel fluorinated 4-quinolone in development for treatment of acute bacterial skin and skin structure infection and community-acquired bacterial pneumonia. This quality control (QC) study was performed to establish ranges for control strains: Staphylococcus aureus ATCC 29213 (0.004 to 0.015 μg/ml), Enterococcus faecalis ATCC 29212 (0.015 to 0.06 μg/ml), Pseudomonas aeruginosa ATCC 2...
