Microencapsulation has become a common technique in the production of controlled release dosage forms. Many results have been reported, concerning the use of alginate beads as controlled release drug formulations. Alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. Ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

The separation and quantitation of phosphorous oxoanions have been investigated by non-suppressed ion chromatography (IC) with conductometric detection using a modified gluconate-borate buffer as eluent. Hypophosphite being coeluted with the injection peak, its previous oxidation into phosphate is necessary. The method was applied to the determination of hypophosphite and phosphate in several p...

The present investigation was focused to formulate semi-solid capsules (SSCs) of hydrophobic drug telmisartan (TLMS) by encapsulating semi-solid matrix of its solid dispersion (SD) in HPMC capsules. The combinational approach was used to reduce the lag time in drug release and improvise its dissolution. SDs of TLMS was prepared using hot fusion method by varying the combinations of Pluronic-F68...

P���� J., C���������� M., J���� M. (2004): Biological and serological procedures to detect three nepoviruses in fruit trees. Plant Protect. Sci., 40: 121–127. Cherry leaf roll virus (CLRV), Myrobalan latent ringspot virus (MLRSV) and Strawberry latent ringspot virus (SLRSV) were transferred by budding to woody trees, hybrid Ishtara, peach cv. GF 305 and cv. Lesiberian. Three buffers with antiox...

the interaction of sodium n-dodecyl sulphate (sds) with histones in phosphate buffer ph 6.4 has been studied spectroscopically and by equilibrium dialysis. the enthalpies of interaction and the spectroscopic data suggest different structural stability for histones-sds interaction. the linear relation between enthaly and absorbtion was determined by the equation of m= , where m is the stability ...

Strains. The strains examined are all maintained in the Pasteur Culture Collection (PCC) and havenow been deposited in the American Type Culture Collection (ATCC). They are identified here by both PCC and ATCC strain numbers. Full strain histories, media employed for cultivation and the explanation of generic terminology are given by Rippka et al. (1979). An additional strain (Oscillatoria agar...

The levels of degradation of cefetamet pivoxil (CAT), cefuroxime axetil (CAE), and cefpodoxime proxetil (CPD) in 0.6 M phosphate buffer (pH 7.4) and human intestinal juice (pH 7.4) at 37 degreesC over 24 h were compared. Significant differences in the time courses of degradation and in the patterns of degradation products were observed. (i) The relative proportions of the Delta2- and Delta3-cep...

The use of fluorescent gel blends with GQDs provides new insights into formation and hydrogen peroxide detection utilizing the peroxidase-like catalytic activity graphene quantum dots. This hybrid hydrogel enhances performance properties by a low molecular weight gelator assistance phosphate buffer taking an advantage sensing application highly potential sensitivity stability.
