turfgrasses are usually important groundcover plants in many landscapes. they occupy the lowest surface of the landscape, close to pollutant particles. so, they can be an attractive option for environmental remediation. today, high concentrations of hazardous chemicals such as lead are among the most serious environmental problems. in vitro selection of turfgrass accumulator or tolerant of toxi...

BACKGROUND The study tests the hypothesis of a reduction of priming due to tree allergy in patients sensitised to both birch/hazel and grass pollen undergoing an associated preseasonal Sublingual/Injective immunotherapy. METHODS 36 out of 49 bisensitized candidates were pair-matched into 18 case-referent couples. During two years all patients were administered preseasonal grass-SIT and one pa...

A grass-fire cycle in Australian tropical savannas has been postulated as driving the regional decline of the obligate-seeding conifer Callitris intratropica and other fire-sensitive components of the regional flora and fauna, due to proliferation of flammable native grasses. We tested the hypothesis that a high-biomass invasive savanna grass drives a positive feedback process where intense fir...

Methods Four groups of patients (n=48) underwent nasal allergen provocation test for grass pollen. We included 12 patients with allergic rhinitis based on grass allergy, 12 patients with CRSwNP without grass allergy, 12 patients with CRSwNP with grass allergy, and 12 control patients. The diagnosis of grass allergy was based on skin prick test and RAST. The test was positive based on change in ...

STUDY POPULATION. Subjects were 278 children (age: 5–14 years) with seasonal grass pollen-induced allergic rhinoconjunctivitis for 2 years. Allergy was confirmed by a timothy grass-specific immunoglobulin E (IgE) level of at least class 2 and a wheal diameter of 3 mm in a skin-prick test containing 5 grass pollens included in the SLIT tablet (orchard, meadow, perennial rye, sweet vernal, and ti...

Introduction The “Grass-fed beef ” label indicates meat that is produced by feeding forages from start to finish without any grain supplementation (USDA-AMS 2007). Many healthful aspects of grass-fed beef have been identified, including lower total fat content and higher content of omega-3 fatty acids, conjugated linoleic acids (CLA), and antioxidants as compared to feedlot-finished beef (Razmi...
