Background: Medicinal plants are considered new resources for producing agents that could act as alternatives to antibiotics in the treatment of antibiotic-resistant bacteria. The aim of this study was to evaluate the antibacterial activity of 28 plant extracts and oils against four Gram-negative bacterial species.Methods: Experimental, in vitro, evaluation of the activities of 28 plant extract...

Percutaneous Coronary Intervention To the Editor: We read with interest the article by Chew et al1 in the February 20, 2001, issue of Circulation, but we were disappointed that such eminent investigators could confuse associations arising from heterogeneous pooled data with hard evidence on which scientific conclusions can be drawn. In their Conclusions, they state that their meta-analysis “. ....

One plant seed extract (Psidium guajava) was screened for their bioreduction behavior for synthesis of silver nanoparticles. Psidium guajava (PG) was found to exhibit the good reducing and protecting action in terms of synthesis rate and monodispersity of the prepared silver nanoparticles. UV–visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmis...

The Emergency Medical Treatment and Labor Act (EMTALA) is a federal law established in 1986 to ensure that patients who present an emergency department receive medical care regardless of means. Violations are reported the Centers for Medicare Medicaid Services can result significant financial penalties. Cheng et al1Cheng T.W. Farber A. Forsyth A.M. Levin S.R. Haqqani M.

We examined the influences of Ca2+ and crossbridge kinetics on the maximum rate of force development during Ca2+ activation of cardiac myofibrils and on the maximum rate of relaxation. Flash photolysis of diazo-2 or nitrophenyl-EGTA was used to produce a sudden decrease or increase, respectively, in [Ca2+] within Triton-skinned trabeculae from rat and guinea pig hearts (22 degrees C). Trabecula...

The properties relevant to pharmacokinetics and pharmacodynamics of four series of synthesized s-triazine derivatives have been studied by Quantitative structure-retention relationship (QSRR) approach. The chromatographic behavior of these compounds was investigated by using reversed-phase high performance thin-layer chromatography (RP-HPTLC). Chromatographic retention (RM0) was correlated with...
