The ability of calcium loaded heavy sarcoplasmic reticulum vesicles to specifically respond to the addition of various agents such as caffeine, calcium ions and calmodulin antagonists to rapidly released calcium can largely be diminished by passing the vesicular suspension it 0.3 M sucrose, 0.6 M KCl, 4 mM CaCl2, pH 7.0 through a Sepharose 6B column or by centrifuging it through a sucrose gradi...
An anticoagulant has been purified from the body fluid of Ascaris suum by sequential passage through Sephadex G-50, CM-cellulose and Sephadex G-25 columns then treated with 2 M NaCl, passaged through a Sephadex G-25 column, separated from the phosphate buffer by precipitation of the latter with the CaCl2, then passaged through a Sephadex G-10 column in water. In the body fluid of the worm, the ...
Copper (Cu) is an essential micronutrient for plants. However, determination of a suitable extractant of Cu in sewage sludge-amended calcareous soils has seldom been attended. The aim of this research was evaluating several extractants to predict available Cu in 10 untreated and sewage sludge-treated calcareous soils in greenhouse under wheat cultivation. After 1 month incubation, available Cu ...
Hamadan province is one of the most important alfalfa (Medicago sativa) producing regions in Iran. However, little is known about P status in this region and no suitable extraction method has yet been introduced. This experiment was carried out to determine the available phosphorus by nine chemical extractants in some soils of the Hamadan region. The treatments consisted of 15 soils and 2 P lev...
BACKGROUND Surgical castration is widely used to sterilize male dogs, but has significant impacts on time to perform the operation, recovery of the animals as well as cost, which can limit population control programs. Previous research has shown intratesticular injection of calcium chloride dihydrate (CaCl2) in saline to be a promising alternative to surgery. However, long-term azoospermia was ...
شوری یکی از عوامل مهم محدود کننده تولید محصولات کشاورزی در دنیا است. انواعی از نمک ها باعث شور شدن خاک می گردند که اثرات متفاوتی بر صفات مورفولوژیکی و فیزیولوژیکی گیاه دارند. .aloe vera l یکی از گیاهان دارویی مهم دنیا بوده که در درمان بسیاری از بیماری ها و عوارض پوستی استفاده فراوان دارد. به منظور ارزیابی اثر تنش شوری ناشی از نمک های کلریدسدیم و کلریدکلسیم بر میزان ژل، برخی شاخص های رشد، برخی ش...
BACKGROUND Normal ionic perfusate containing butanedione monoxime (BDM), a reversible myofilament inhibitor, could be better than either a high potassium (KCl) or a low calcium (CaCl2) perfusate for long-term cardiac preservation. This hypothesis was tested in 70 isolated guinea pig hearts. METHODS AND RESULTS Three groups--time control (8 hours, 37 degrees C), cold control (22 hours, 3.8 deg...
‘Golden Delicious’ apples (Malus /domestica Borkh.) were either untreated or pressure-infiltrated after harvest with 0, 1, 2, 3 or 4% CaCl2 solutions (w/v) and stored at 0 8C for up to 6 months. The chemical composition of the fruit cortical tissue and cell walls of the 2 /4 mm layer under the epidermis was studied. Storage of untreated fruit resulted in a decrease in K, P, Mg, S and Suc conten...
INTRODUCTION This in vitro study investigated the effect of adding 10% calcium chloride (CaCl2) on push out bond strength of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA) to root canal dentin. METHODS AND MATERIALS A total of 120 root dentin slices with 2 mm thickness were prepared from sixty single-rooted human teeth. Dentinal discs were enlarged to achieve 1.3 m...
OBJECTIVE Endothelium-derived nitric oxide (EDNO) has been shown to have vascular, metabolic, and contractile effects in the heart. We evaluated these effects during intracoronary (i.c.) administration of CaCl2 in dogs. METHODS The left anterior descending coronary artery of nine anesthetized, open-chest dogs was perfused at controlled pressure (80 mm Hg) with arterial blood. Coronary blood f...
