Background: Plants are an important natural source of compounds used in cancer therapy. Pancratium maritimum contains potential anti-cancer agents such as alkaloids. In this study, we investigated the anti-proliferative effects of P. maritimum extracts on MDA-MB-231 human epithelial adenocarcinoma cell line and on normal lymphocytes in vitro. Methods: Leaves, flowers, roots, and bulbs of P. mar...

Hepatocytes were isolated from eight species of birds ranging from 13 g zebra finches to 35 kg emus. This represents a 2800-fold range of body mass (Mb). Liver mass (g) was allometrically related to species body mass by the equation: liver mass=19.6 x Mb(0.91). There was a significant allometric decline in hepatocyte respiration rate (HRR; nmol O2 mg(-1) dry mass min(-1)) with species body mass...

This study focused on the adsorption in aqueous solution of methylene blue (MB), a cationic dye used textile industry, by crushed Argan shells (used as raw materials) from southern region Morocco. These were first characterized different technical analyses: elemental analysis, biochemical IR spectroscopy, thermogravimetric scanning electron microscopy, mercury porosimetry, and zetametry. The ki...

In the heavy quark limit, the heavy baryon LQ (Q5b or c) can be regarded as composed of a heavy quark and a scalar light diquark which has good spin and flavor quantum numbers. Based on this picture we establish the Bethe-Salpeter ~BS! equation for LQ in the leading order of 1/mQ expansion. With the kernel containing both the scalar confinement and one-gluon-exchange terms we solve the BS equat...

This is the final paper in or series examining the link between the energetics and mechanics of terrestrial locomotion. In this paper the kinetic energy of the limbs and body relative to the centre of mass (EKE, tot of paper two) is combined with the potential plus kinetic energy of the centre of mass (ECM, tot of paper three) to obtain the total mechanical energy (excluding elastic energy) of ...

I discuss QCD sum rules determinations of the form factors governing the decay B ! ( )` . For some of these form factors the computed dependence on the momentum transferred does not agree with the expectation from the nearest pole dominance hypothesis. Relations are observed among the form factors, that seem to be compatible with equations recently derived by B.Stech. The measurement of a numbe...

vitamin b6 is a cofactor of various enzymes influencing numerous neurotransmitters in the brain such as norepinephrin, and serotonin . since these neurotransmitters influence mood , the aim the present work to evaluate the effect of vitamin b6 on depression and obsessive compulsive behavior when coadministred with clomipramine, fluoxetine, or venlafaxine. male mice weighing 25-30 g were used. t...
