  In a three-year (2004-2006), field experiment, we aimed to study changes in leaf physiological traits (leaf water potential-Ψleaf, leaf water content-LWC, carbon isotope discrimination-Δ, specific leaf area-SLA, chlorophyll content as assessed by SPAD and modified SPAD-MSPAD) and elemental composition (K, Na, Ca, Mg, K/Na, Ca/Mg, total leaf salinity-TLS) of sugar beets (cv. Rizor) grown unde...

This experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (Triticum aestivum L.) and durum (Triticum turgidum L.) wheats in seedling stage. A greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. Different agronomic and physiol...

foliar analysis of natural deciduous tree species of basswood (tilia americana l.) (ba), american beech (acer grandifolia enrh) (be), and white ash (fraxinus americana l.) (wa) was carried out in 1994 in southern quebec. the diagnosis and recommendation integrated system (dris) was developed from the traditional method to find the preliminary norm and indices of n, p, k, ca, and mg for the ...

Smooth muscle cells of seminal vesicle exhibit excitatcry junction patential on nerve stimulation and can fire evoked) action potential (1). However) the type of ion channels that underlie this electrical activity have not been described. I have investigated the type and pharmacology of ion channel in freshly isolated smooth muscle cells from the guinea-pig seminal vesicle using whole-cell patc...

Introduction: To assess the salivary composition of proteins and minerals in smokers compared with non-smokers.   Materials and Methods: In this study we compared the total protein and Ca, Na, K, Mg, Pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years.   Results: Fifty-nine participants were evaluated. The mean age was 33.14±5.32 years among smo...

The interaction between eriochrome black T and Li , Na , K ,Mg and Ca ions in acetone and dimethylsulphoxide solutions has been investigated spectrophotometrically. The formation constants of the resulting 1 : 1 complexes were determined and found to decrease in the order Mg >Ca >Li >K >Na in both solvents used. There is an inverse relationship between the stabilities of the complexes...

background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...
