Background and Aims: Cardiac hypertrophy is a compensatory augmentation response of the heart due to pressure overload that can lead to heart failure. Carvacrol is considered as the major compound of many plants, that possesses strong antioxidant properties. The present study aimed to evaluate effect of carvacrol on catalase activity and mRNA expression following left ventricular hypertrop...

Earlier studies (Baeckström et al., J. Biol. Chem., 266: 21537-21547, 1991) have revealed that the colon carcinoma cell line COLO 205 produces two different proteins carrying the carcinoma-associated sialyl-Le(a) carbohydrate epitope. One is the MUC1 mucin apoprotein, and the other protein is smaller and has not been characterized in detail. This paper describes a comparison of COLO 205 with th...

Droplet size is one of the most important factors that affect spray deposition and weed control through use herbicides. The aim this study was to evaluate influence droplet on Euphorbia heterophylla Urochloa ruziziensis by using glyphosate. treatments included spraying glyphosate with fine, medium, coarse, very ultra-coarse sizes determine deposition, uniformity distribution, visual control, dr...

Apigenin is a plant flavonoid which has been shown to significantly inhibit UV-induced mouse skin tumorigenesis when applied topically, and may represent an alternative sunscreen agent in humans. We have investigated the molecular mechanism(s) by which apigenin inhibits skin tumorigenesis. Initial studies examined the effects of apigenin on the cell cycle. DNA flow cytometric analysis indicated...

Phase I studies of p.o. administered nolatrexed dihydrochloride (AG337, THYMITAQ), a nonclassical thymidylate synthase inhibitor, were performed to establish the maximum tolerated dose and a recommended dose for Phase II studies. The bioavailability and pharmacokinetic and pharmacodynamic properties of oral nolatrexed were also studied. Forty-five patients were treated with oral nolatrexed ever...

The encoding of luminance contrast by ON-OFF amacrine cells was investigated by intracellular recording in the retina of the tiger salamander (Ambystoma tigrinum). Contrast flashes of positive and negative polarity were applied at the center of the receptive field while the entire retina was light adapted to a background field of 20 cd/m(2). Many amacrine cells showed remarkably high contrast g...

Three subspecies of Artemisia tridentata occupy distinct habitats in the Great Basin of North America: ssp. wyomingensis in low, arid elevations; ssp. vaseyana in high, mesic elevations; and ssp. tridentata in intermediate zones. We evaluated differences in the drought experienced and drought tolerance among the subspecies. Drought tolerance was measured by two traits: the xylem pressure (Cx) c...
