OBJECTIVE To evaluate whether adolescents with a positive score in a screening tool for possible eating disorders (ED) have a different diet intake in comparison with those with a negative score. METHODS Cross-sectional study performed in 235 adolescents (37.9 % boys) from Zaragoza (Spain). Age,

The effect of abscisic acid (ABA) on uptake of potassium ((86)Bb(+) or (42)K(+)) by Avena sativa L. coleoptile sections was investigated. ABA lowered the potassium uptake rate within 30 min after its application and inhibition reached a maximum (ca. 75%) after 2 h. The inhibition of K(+) uptake

The purpose of this study was to determine the remediation effect of various substances (manure, clay, charcoal, zeolite and calcium oxide) on limiting the influence of high cobalt doses (0, 20, 40, 80, 160 and 320 mg/kg of soil) on the content of macroelements in grain, straw and roots of oat. The

Some physical and chemical properties of four oat (Avena sativa L.) varieties (BDMY-6, BDMY-7, Che-Chois and Y-2330) harvested from Konya in Turkey were investigated. The weight of the grain, moisture, crude protein, crude ash, crude fibre, crude energy, crude oil and water-soluble extract contents

The action of auxin in the promotion of growth has been suggested in the literature to depend on cell wall acidification. In a former investigation by the present authors the electrochemical balance in auxin-induced proton extrusion was shown to be maintained by potassium net uptake. The present

Copper based pesticides are used to protect vineyards from fungal infections. Plants like black oats (Avena strigosa Schreb) can promote chemical changes in the rhizosphere, reducing copper (Cu) bioavailability in contaminated soils. The objective of this study was to evaluate how copper additions

OBJECTIVE Animal studies report that oat (Avena sativa L) intake has favorable effects on kidney function. However, the effects of oat consumption have not been assessed in humans. The aim of this study was to examine the impact of oat intake on biomarkers of renal function in patients with chronic

The purpose of this study was to determine the effect of soil contamination with Hg on the yield and chemical composition of Avena sativa L. Mercury was incorporated into soil in amounts: 0, 50, 100 and 150 mg Hg·kg^-1of soil. Zeolite, lime and bentonite were used to alleviate the

Fly ash (FA) and bottom ash (BA) from a softwood pellet boiler were characterized and evaluated as soil amendments. In a greenhouse study, two plant species (rye grass, Lolium perenne L. and oats, Avena sativa) were grown in three different treatments (1% FA, 1% BA, non-amended control) of a silty

The particulate glucan synthetase preparation isolated from a homogenate of oat coleoptiles at 4 C lost 65% of its original activity after 1 day when the UDP-d-glucose substrate concentration was 5 x 10(-7)m to 1.0 x 10(-6)m. Storage of the particulate enzyme at -20 C or in liquid nitrogen did not

Segments of oat (Avena sativa L.) roots which had been exposed to 1 millimolar CdSO(4) in quarter-strength Hoagland No. 1 solution exhibited decreased respiratory rates, ATP levels, membrane-bound ATPase activity, and reduced K(+) fluxes. Respiration and ATP levels were decreased after a 2-hour

The possibility was investigated that diethylstilbestrol (DES) inhibits potassium absorption in oat (Avena sativa L. cv. Goodfield) roots by inhibiting mitochondrial functions in addition to inhibiting the plasma membrane ATPase. DES at 10(-6) molar stimulated the mitochondrial ATPase slightly, but

K(+) and Na(+) fluxes and ion content have been studied in roots of Atriplex nummularia Lindl. and Avena sativa L. cv Goodfield grown in 3 millimolar K(+) with or without 3 or 50 millimolar NaCl. Compartmental analysis was carried out with entire root systems under steady-state conditions.Increasing

Uptake of the lipophilic cation triphenylmethylphosphonium into mesophyll protoplasts of oat (Avena sativa L. cv. "Garry") approaches equilibrium at 3 to 4 hours. The resulting external and internal concentrations are then used with the Nernst equation to obtain a membrane potential of -62
