Mitochondria isolated from the ascites form of L1210 mouse leukemia cells readily accumulate Ca(2+) from the suspending medium and eject H(+) during oxidation of succinate in the presence of phosphate and Mg(2+), with normal stoichiometry between Ca(2+) uptake and electron transport. Ca(2+) loads up to 1600 ng-atoms per mg of protein are attained. As is the case in mitochondria from normal tiss...

The performance of autumn and spring-planted strawberry cv. ‘Elsanta’ in peat supplemented with fresh spent mushroom substrate (SMS) Agaricus bisporus, Lentinus edodes, Pleurotus ostreatus 15% 25% was evaluated. morphological yield parameters, dry matter distribution, uptake, partitioning macro- micronutrients were studied. experiment carried out during 2020–2021 an unheated tunnel laid a rando...

A four-month study was conducted in a greenhouse with Larix laricina grown on sand and nursery soil. This culture was fertilized with anaerobically digested sludge at various rates and doses. No direct relationship could be established between the growth of seedlings and the quantities of sludge applied. Relationships were, however, established between the quantities of sludge applied and the e...

tomato  (l.ycopersicon esculentum  mill.) cv. rio grande  seedlings were nutritionally conditioned with solutions complete fertilizer n(60% no3+40% nh4)-p-k (20-20-20) , n(30%no3+70% nh4)-p-k (15-5-30) , the first two week   n(60% no3+40% nh4)-p-k (20-20-20) and later two week  n(30%no3+70% nh4)-p-k (15-5-30)  and vice versa were  applied in  completely randomized experiment with three replicat...

High exposures to fluoride (F) may occur in environments rich in F from natural or industrial sources and from misuse of F-containing dental care products, particularly by children. Both acute and chronic exposures to elevated levels of F have negative effects on several calcium-dependent processes, including kidney glomerular and tubular function. We examined the effect of chronic F ingestion ...

Con el objetivo de estudiar las características agronómicas y la acumulación nutrimentos en materia seca (MS) durante un ciclo completo planta agave, experimento establecido sur Tamaulipas se plantaron hijuelos agave tres condiciones manejo del fertilizante: a) En temporal sin fertilizante, Testigo Absoluto (TA); b) Fertigación, además precipitación, recibieron agua (N, P, K, Ca, Mg, micronutri...
