Rhodopseudomonas gelatinosa grows on citrate anaerobically in the light. Under aerobic conditions citrate cannot be utilized. Citrate is rapidly fermented by Rps. gelatinosa in the dark, and this fermentation is associated with limited growth (one generation). Anaerobically in the light citrate is decomposed much faster than its catabolic products can be used for the synthesis of cellular mater...

Background: Endothelial dysfunction can influence fertility rate in women with polycystic ovary syndrome (PCOS) as flow mediated dilatation (FMD) is impaired in patients with the disease. The aim of this study was to compare two methods of ovulation induction by letrozole or letrozole plus human menopausal gonadotropins (HMGs) in infertile women with PCOS who were resistant to clomiphene citrat...

The effectiveness of sodium citrate and sodium citrate/ranitidine were compared in two randomised groups of elective caesarean patients during the various phases of anaesthesia. The mean pH values (3.5, 3.3, 3.6) were lower in the citrate group compared to the citrate/ranitidine group (6.1, 6.3, 5.9). The percentage of patients with pH values less than 2.5 was 40% in the citrate group compared ...

The outcome of ovulation induction in anovulatory polycystic ovarian syndrome (PCOS) may depend, in part, on the pharmacologic compounds used, but also on individual patient characteristics, such as age, body mass index (BMI), hyperandrogenism, luteinizing hormone (LH), hyper-secretion, anti mullerian hormone (AMH) levels and possibly antral follicle count (AFC) with ovarian volume of these wom...

Carrier-mediated citrate transport has been demonstrated and characterized at 10°in mitochondria from Morris hepatomas 3924A and 16 and in normal and host liver preparations by the inhibitor-stop technique using 1,2,3-benzenetricarboxylate. We studied: (a) citrate influx in exchange for endogenous substrates; (b) citrate influx into mitochondria loaded with citrate; (c) citrate efflux from cit...

In an attempt to identify components of a ferric citrate uptake system in Pseudomonas aeruginosa, a mutant library of a siderophore-deficient strain (IA614) was constructed and screened for defects in citrate-promoted growth in an Fe-restricted medium. A mutant disrupted in gene PA3901, encoding a homologue of the outer-membrane ferric citrate receptor, FecA, of Escherichia coli (FecA(E.c.)), w...

Background: Clomiphene citrate (CC) is still holding its place as the first-line treatment for induction of ovulation in polycystic ovary syndrome (PCOS) patients.  Objective: to assess effect extended clomiphene on pregnancy outcomes resistant PCOS. Patients and methods: this study was conducted 48 PCO patients with CC resistance attended Obstetrics Gynecology Outpatient Clinic at Menoufia U...

When cells of Pseudomonas are grown on citrate as the sole carbon source they oxidize citrate and isocitrate rapidly. Fluorocitrate inhibits the oxidation of citrate. Fluorocitrate-treated cells accumulate [6-(14)C]citrate, as shown by a rapid Millipore-filtration technique. In the absence of fluorocitrate most of the [6-(14)C]-citrate is lost in the form of (14)CO(2). The isolation of a pseudo...

Vitamin B(12), reduced by titanium (III) citrate to vitamin B(12s), catalyzes the reductive dechlorination of chlorophenols. Reductive dechlorination of pentachlorophenol and of all tetrachlorophenol and trichlorophenol isomers was observed. Reaction of various chlorophenols with vitamin B(12) favored reductive dechlorination at positions adjacent to another chlorinated carbon, but chlorines or...

Polycystic ovarian syndrome (PCOS) is a disorder of androgen excess and ovarian dysfunction. Hirsutism and elevated free testosterone levels are the most consistent signs of the androgen excess. Irregular, infrequent, or absent menses and infertility are symptoms of ovulatory dysfunction. Obesity is also a feature of this syndrome and contributes to associated metabolic abnormalities. Lifestyle...
