1. The effects of ATP, inorganic phosphate and citrate on the relationship between fructose 6-phosphate concentration and initial velocity of reaction has been investigated with a partially purified preparation of rat-heart phosphofructokinase. 2. At low concentrations of ATP (<80mum) rate curves for fructose 6-phosphate approximated to Michaelis-Menten kinetics. At higher ATP concentrations ra...

Aim: To compare the efficacy of letrozole and clomiphene citrate in women having anovulatory infertility. Study design: Randomized Controlled Trial. Place duration study: 16th October 2020 to 15th September 2021 Department Obstetrics &amp; Gynecology, Shahida Islam Medical Complex Lodhran. Methods: In our study 112 patients between ages 18 40 years with anovulation were included. Patients H/O p...

Background: Urine citrate and oxalate levels are risk markers for renal stone formation. measurements prone to interferences linearity issues. This study investigates modification of sample preparation citric acid assay using the pH adjusted purified urine used analysis. Methods: samples were diluted 1:1 with diluent (Trinity Biotech Oxalate), vortexed between 6 8. Diluted transferred into puri...

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...

Derivative spectrophotometric procedures and an isocratic high performance liquid chromatographic method for the determination of butamyrate citrate (Sinecod, Safarol) in cough syrups have been developed. In the spectrophotometric method, direct measurement of the drug at its absorption maxima is impossible because of interference from different absorbing excipients. Extraction of butamyrate ci...

BACKGROUND The most appropriate lock solution for central venous access devices is still to be defined. GAVeCeLT - the Italian group for venous access devices - has developed a consensus on the evidence-based criteria for the choice and the clinical use of the most appropriate lock solution for central venous catheters (excluding dialysis catheters). METHOD After the constitution of a panel o...

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...
