A facile and sensitive colorimetric detection method for sildenafil citrate (SLDC) has been developed by using polyvinyl alcohol-citrate-stabilized silver nanoparticles (PVA-Cit-AgNPs). The sensitivity selectivity of were investigated in detail. PVA-Cit-AgNPs could be induced to aggregate immediately the presence SLDC, especially after addition 0.1 M HCl solution. SLD detected response AgNPs th...

In Lactococcus lactis subsp. lactis biovar diacetylactis, citrate transport is facilitated by the plasmid-encoded citrate permease (CitP). In this work, we analysed regulation of citrate utilization by pH, nutrient limitation and the presence of citrate at four different levels: (i) plasmid copy number, (ii) citP transcription, (iii) citP mRNA processing and (iv) citrate utilization capacity. C...

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 ...

The size, size distribution and magnetic properties of magnetite nanoparticles (NPs) prepared by co-precipitation without citrate, in the presence citrate adsorbed post-synthesis were studied X-ray Diffraction (XRD), Dynamic Light Scattering (DLS), Electron Paramagnetic Resonance (EPR) magnetization measurements. aim this investigation was to clarify effect ions on NPs. primary NPs, as determin...

Six selective media, namely xylose lysine desoxycholate agar (XLD), desoxycholate citrate agar (DCA), desoxycholate citrate lactose saccharose agar (DCLS), Salmonella Shigella agar (SS), bismuth sulphiteagar (BS) and brilliant green agar (BG), were compared for recovering Salmonella from pure cultures using the pour plate method. BS agar was superior to alt-the other agars in supporting growth ...

Citrate is the preferred anticoagulant for blood collection, as EDTA damages platelets and heparin modifies their function (1). Citrate allows the rapid generation of plateletrich plasma (PRP), with a high yield of platelets; however, this method has certain disadvantages. In particular, the PRP preparation has a limited stability (no longer than 2 h) and contains plasma proteins, including enz...

Potassium citrate is prescribed to decrease stone recurrence in patients with calcium nephrolithiasis. Citrate binds intestinal and urine calcium and increases urine pH. Citrate, metabolized to bicarbonate, should decrease calcium excretion by reducing bone resorption and increasing renal calcium reabsorption. However, citrate binding to intestinal calcium may increase absorption and renal excr...

There are rising public health concerns about the links between consumption of sugar-sweetened beverages and weight gain, obesity, and other metabolic problems. Sodium citrate (Na-citrate) is used as an additive in colas and various commercial drinks worldwide. Although potassium citrate (K-citrate) has been prescribed and well accepted by urologists for treating urinary stone disease (urolithi...

It has been known for about seventy years that bone, in all vertebrates, contains uniquely high citrate levels. However, the role of citrate, its source, its regulation, and its implication in normal bone formation and in bone disorders have remained largely unknown. For the past thirty-five years, the relationship of citrate in bone has been a neglected area of attention and research. It has r...
