background due to danger of spillage of cyst materials during surgery, chemoprophylaxis is routinely recommended for cyctic echinococcosis. however, for prophylactic purposes the time for starting and the duration of administration of prophylactic drug regimen is not yet clear. the aim of the present study was to evaluate the chemoprophylactic efficacy of one month administration of albendazole...
This study had two goals: 1) measure hematologic changes with high-altitude acclimatization in horses; and 2) assess the effect of 9 days at high altitude on subsequent athletic performance at low altitude. Six horses performed standardized exercise tests on a dirt track (before and during time at altitude) and treadmill (pre- and postaltitude exposure). Resting and immediate postexercise blood...
Little information exists on the potential for N fertilizer application to corn ( L.) to affect NO emissions during subsequent unfertilized crops in a rotation. To determine if N fertilizer application to corn affects NO emissions during subsequent crops in rotation, we measured NO emissions for 3 yr (2011-2013) in an Iowa, corn-soybean [ (L.) Merr.] rotation with three N fertilizer rates appli...
OBJECTIVE This study evaluated the effects of three post-brushing mouthwashes containing 0 ppm F, 225 ppm F, and 500 ppm F, respectively, on salivary fluoride retention after brushing with 1450 ppm fluoride (as NaF) toothpaste and rinsing with water immediately after brushing. METHODS In this three-phase, randomized, cross-over study, an ion-specific electrode was used to measure salivary F l...
In order to evaluate the effects of supplementary irrigation and municipal solid waste compost on growth and yield of two chickpea cultivars under dryland condition, a field experiment was arranged in Khoramabad, Iran, in 2008-2009. The experimental design was split-split plots with randomized complete blocks with three replications. Four levels of irrigation as main plot including dryland (as ...
Three-year field trials were set up on eutric brown soil in northwestern Croatia (Zagreb) with the objective to determine the effect of plant density and nitrogen rates on the formation and size of leaf area of seed sugar beet, and on the yield and seed quality in seed production without transplanting. Investigations should also reveal how much the yield and quality of sugar beet seed depend on...
Safflower (Carthamus tinctorius L:) usually grown as a source of oil can be also used as fodder either for hay or ensiling purposes, particularly in semiarid regions. In 2002-2003 a research project was carried out in Southern Italy to evaluate the production and forage quality of safflower biomass cv Centennial (high oleic), harvested at three different stage: May 14 (at complete appearance of...
Periodical organisms, such as bamboos and periodical cicadas, are very famous for their synchronous reproduction. In bamboos and other periodical plants, the synchronicity of mass-flowering and withering has been often reported indicating these species are monocarpic (semelparous) species. Therefore, synchronicity and periodicity are often suspected to be fairly tightly coupled traits in these ...
background & aim: deanaie thyme (thymus daenensis celak.), a member of the lamiaceae family. thymus in one of the most important medicinal and aromatic plants that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. recent studies have showed that thyme have strong antibacterial, antifungal, spasmolytic and antioxidant activities. experimental: ...
Flowering and vegetative growth were assessed in 19 half-sib families of Alnus rubra Bong. planted in a replicated field trial near Olympia, Washington, USA. The trial consisted of three square spacings (0.5, 1.0 and 2.0 m), two irrigation regimes (low and high), and two fertilization treatments (0 and 300 kg P ha(-1)). Male and female flowers were surveyed in all plots for all families at plan...
