the effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male wistar rats were investigated. daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations by 1...

A 22 years old lady was admitted because of progressive dyspnea, severe abdominal protrusion and lower extremity edema. She had undergone ovarian hyperstimulation for primary infertility by Clomiphen and Human chorionic gonadotropin for 3 months. Abdominopelvic ultrasonography revealed bilateral enlarged multi cystic ovaries and massive ascites. Transesophageal echocardiography revealed a large...

BACKGROUND AND AIMS Aluminium (Al) stimulates the efflux of citrate from apices of rice bean (Vigna umbellata) roots. This response is delayed at least 3 h when roots are exposed to 50 microm Al, indicating that some inducible processes leading to citrate efflux are involved. The physiological bases responsible for the delayed response were examined here. METHODS The effects of several antago...

Background: One of the most common causes of infertility in women is ovulatory dysfunction (PCOS) and the choice of treatment is clomiphene citrate. One of the mechanism of dichotomy between the rate of ovulation and pregnancy is anti estrogenic effects of clomiphene citrate on endometrium. According to its long half life, the anti estrogenic effects probably exacerbate in consecutive cycles. W...

Previous work (Birnberg, Jayroe, Hanson 1982 Plant Physiol 70: 511-516) demonstrated that corn mitochondria (Zea mays L.) can accumulate citrate by a malate- and phosphate-independent proton symporter. This uptake and symport of other ions were investigated. Passive swelling experiments indicated that corn mitochondria can accumulate several other anions by proton symport, but only isocitrate i...

Several strains of non-citrate-metabolizing Pediococcus halophilus have previously been isolated from soy sauce mash or moromi. The factors controlling the metabolism of citrate in soy pediococci were studied. All the soy pediococcal strains tested which failed to decompose citrate did not possess citrate lyase [citrate (pro-3S)-lyase; EC 4.1.3.6] activity. In P. halophilus, citrate lyase was a...

Mammalian cells accumulate iron from ferric citrate or ferric nitrilotriacetate through the activity of a transferrin-independent iron transport system [Sturrock, Alexander, Lamb, Craven and Kaplan (1990) J. Biol. Chem. 265, 3139-3145]. The uptake system might recognize and transport ferric-anion complexes, or cells may reduce ferric iron at the surface and then transport ferrous iron. To disti...

for evaluation of citric acid and citrate effects on bovine epididymal protoplasmic droplets, fifty bovine testes were collected in the october 2007 till june 2008 from urmia slaughterhouse and transported to the laboratory in a cool container filled with 5 °c ice pack. caudal epididymis was incised and sperm cells were put into petri dishes containing hams f10 media with 10% fetal calf serum (...
