OBJECTIVE In addition to P2Y12 receptor antagonism, ticagrelor inhibits adenosine cell uptake. Prior data show that 7-day pretreatment with ticagrelor limits infarct size. We explored the acute effects of ticagrelor and clopidogrel on infarct size and potential long-term effects on heart function. APPROACH AND RESULTS Rats underwent 30-minute ischemia per 24-hour reperfusion. (1) Ticagrelor (...

In vitro flowering and effective micropropagation protocol were studied in Swertia chirayita, an important medicinal plant using axillary bud explants. The Murashige and Skoog's medium (MS) supplemented with benzyl amino purine (BAP) 1.0 mg L(-1) and adenine sulfate 70.0 mg L(-1) was found optimum for production of multiple shoots. In the present study, incubation of flowering cultures on BAP s...

The patterns of nitrate reductase activity (NRA) in the leaves (in vivo assay) and root nodule nitrogenase activity (C(2)H(2) reduction) were investigated throughout the season in field-grown Phaseolus vulgaris plants.Maximal NRA (per g fresh weight) occurred at early stages of leaf development but total activity (per leaf) was maximal when the leaf reached full size. In mature plants, most NRA...

Pineapple can be affected by fruit collapse, a disease caused the bacterium Dickeya zeae. However, adequate fertilization increase fruit’s resistance to this illness. Therefore, impact of preharvest foliar calcium and silicon on pineapple quality collapse incidence was assessed in study. The experiment implemented split-plot design with two factors. first factor has terms inoculation (flower in...

The objectives of this experiment were to determine the effects of different application rates of an enzyme hydrolyzed animal protein biostimulant (Pepton) compared to a standard application rate of a biostimulant derived from seaweed extract (Acadian) on plant growth parameters and yield of gold cherry tomatoes (Solanum lycopersicum L.). Biostimulant treatments were applied starting at 15 days...

BACKGROUND The effect of herbivory on plant fitness varies widely. Understanding the causes of this variation is of considerable interest because of its implications for plant population dynamics and trait evolution. We experimentally defoliated the annual herb Arabidopsis thaliana in a natural population in Sweden to test the hypotheses that (a) plant fitness decreases with increasing damage, ...

this experiment was conducted for estimating the effect of row spacing and plant density on soil moisture change, wheat yield and water use efficiency in rainfed condition, using a three replicated randomized complete block design with factorial arrangement at gorgan university of agricultural sciences and natural resources farm in anbare-ololum region in 2008-2009. the treatments that used wer...
