Background: The aim of present study was to estimate the levels of some minerals ( Zn, Se , Ca , Mg , Na and K ).Also relationships between mentioned components and some sperm parameters and the infertility period were studied as well. Materials and Methods: This study was performed on human semen specimens obtained from Asthenospermic patients (101 specimens) and Normospermic males (61 specime...
todays, the world development is facing serious water quality issues. since protect of water quality and ecosystem healthy is an important aspect of ecohydrology. the present research aimed to analyze the temporal trends of water quality parameters of mashin zard river station in order to planning long term management approaches. in this research, trend of some significant factors of water qual...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
In this research the ion exchange potential of natrolite towards K+, Tl+, Cs+, Ca+2, Ni+2, Cu2+, and Co2+ in their melted salts was investigated. The effect of temperature, reaction time and zeolite to salt ratio on the exchange relation was studied. The exchange of Ca2+, Ni2+, Cu2+, and Co2+ was negligible and was equal to 2.59, 6.29, 3.14 and 5.04 percent respectively whereas the exchange of...
embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. this developmental change is accompanied with a great deal of ion channel expression and functions. mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. in the present study some properties of the k + -current...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
In this study, the mineral contents of bread with boiled grape, date, carob and mulberry fruit juices at five different concentrations were determined. The fluctuations of B and Cu contents in bread with pekmez (molasses) were determined between 4.10 to 4.49 mg/kg and 2.74 and 3.34 mg/kg respectively. Ca, Mg, K, P and S were the main macro-elements of bread samples. The highest values of Ca...
در این مطالعه پارامترهای یونی (Na+، K+، Mg+2و Ca+2) و فاکتورهای متابولیک (کلسترول، پروتئین کل و گلوکز) در سرم خون و ارتباط بین آنها در 28 عدد ماهی گاریز(Liza klunzingeri) صید شده در سواحل استان هرمزگان(خلیج فارس) بررسی گردید. نتایج نشان می دهد که میزان های Na+، K+، Mg+2و Ca+2 دارای بیشترین تا کمترین...
measurements of pb, cu, zn, as, ni, hg, and fe heavy metals and major elements and components such as ca, hco3, so4, na, k, mg and cl in soluble rain fractions were performed on rainwater collected at arak plain during the rainy seasons of 2012. concentrations of the heavy metals in the soluble fractions decreased for fe, pb, zn, ni, cu, as and hg, respectively and the major elements and compon...
Tertiary acidic to intermediate volcanic activities and the role of fault zones in Sarbisheh area have provided suitable conditions for the formation of bentonite, especially in pyroclastic deposits. Southeast Gondakan, Kalateh Pedaran, Golab, Golestan, Asfich, Hasan Kolangi, and Kangan bentonites in 1/100000 geological map of Sarbisheh were selected as the case study. Satellite image processin...
