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 smokers and...

background: this study was aimed to assess the effects of angiotensin ii (ang ii) supplementation to the in vitro maturation (ivm) and in vitro culture (ivc) media of vitrified-warmed ovine oocytes on their developmental competence and expression of na+/k+/atpase in resulting embryos. methods: the slaughterhouse-derived immature oocytes (n=1069) were randomly distributed into four experimental ...

Matricaria chamomilla is a medicinal plant that is widely cultivated in salt affected soils. This investigation was undertaken to study the effect of NaCl concentration on germination, and the physiological, biochemical and growth characteristics of chamomile. Seed germination and growth were studied at five NaCl concentration levels (0, 40, 80, 120 and 190 mM NaCl concentration). Increasing th...

Two metabolism trials were conducted to determine the effect of altering dietary Na and K on Mg availability. Three dietary treatments (normal K-normal Na, high K-normal Na and high K-high Na) were imposed upon nine crossbred wether lambs in a randomized block design. Each trial consisted of a 5-d diet adjustment, a 10-d preliminary period and a 5-d collection of feed, feces and urine. Increasi...

Resealed human red blood cell ghosts were prepared to contain a range of ADP concentrations at fixed ATP concentrations and vice versa. ATP/ADP ratios ranging from approximately 0.2 to 50 were set and maintained (for up to 45 min) in this system. ATP and ADP concentrations were controlled by the addition of either a phosphoarginine- or phosphocreatine-based regenerating system. Ouabain-sensitiv...

We previously have demonstrated that the colonic P-ATPase alpha subunit cDNA encodes an H,K-ATPase when expressed in Xenopus laevis oocytes. Besides its high level of amino acid homology (75%) with the Na,K-ATPase, the colonic H,K-ATPase also shares a common pharmacological profile with Na,K-ATPase, because both are ouabain-sensitive and Sch 28080-insensitive. These features raise the possibili...
