We evaluated the antiproliferative effect of infusions from Pluchea sagittalis using the Allium cepa test. Infusions in three concentrations (2.5, 5, and 25 g dm-3) of leaves cultivated in three environments (in vitro, acclimatized growth chamber, and field) were used. Six onion bulbs were used for each of the eight treatments, and the mitotic index was obtained from 6000 cells per treatment. I...

The Purpose of the study was the isolation and identification of Urinary tract infection (UTI) bacteria and the evaluation of their susceptibility against antibiotics. In addition, susceptibility and chemotactic behavior of isolated strains were evaluated against medicinal herbal plant extracts. To perform the study, 200 samples were collected from the patients suffering from UTI. Then, the bac...

The Wigner-Araki-Yanase theorem shows that conservation laws limit the accuracy of measurement. Here, we generalize the argument to show that conservation laws limit the accuracy of quantum logic operations. A rigorous lower bound is obtained of the error probability of any physical realization of the controlled-NOT gate under the constraint that the computational basis is represented by a comp...

Effect of abscisic acid (ABA) and polyamines (PAs) [putrescine (Put), spermidine (Spd) and spermine (Spm)] on mitosis in root tips of A. cepa was studied. Treatment with ABA (0.1 to 100 microM) for 24 hr suppressed the mitosis, measured as mitotic index (MI), in a concentration-dependent manner with approx. 50% suppression at 10 microM of ABA. Treatment with different PAs (1 to 100 microM) had ...

Black garlic (BG) is a processed garlic product prepared by heat treatment of whole garlic bulbs (Allium sativum L.) at high temperature under high humidity for several days, resulting in black cloves with a sweet taste. BG has recently been introduced to the Korean market as a product beneficial to health. To clarify how BG changes during the 35 day aging period, the physicochemical characteri...

Antibacterial activity of A. sativum was tested against gram-positive and gram-negative bacterial isolates from Urinary Tract of Indian patients, which were confirmed for resistant against commonly used antibiotics for urinary tract infections. In present study, only five quantities (10, 20, 30, 40 and 50μg) of aqueous allicin from A. sativum cloves and leaves were used, which has antibacterial...
