It is generally recognized that a dependable test of placental function is one of the most urgent needs in obstetrics. The advantages of using various placental enz,ymes as an index of placental function were found in the fact that their measurements are simple procedures. Coryn (1934) showed for the first time that serum alkaline phosphatase is elevated in late pregnancy. Serum alkaline phosph...

Present study consists 18 morphologically different marine bacterial species isolated from coastal Tamil Nadu, examined for production of bioemulsifiers. All the 18 isolate produces bioemulsifiers and exhibit emulsification index (E24) of 85-95% with hydrocarbons containing fatty acids and <75% with other hydrocarbons. Resultant emulsion found stable till day 100 without any phase separation. P...

Eighty-six percent (72 of 84) of heat-labile and heat-stable, none of 141 heat-labile, and 24% (27 of 111) heat-stable enterotoxigenic Escherichia coli isolates from Thailand aggregated in less than 1 M (NH4)2SO4, hemagglutinated human group A and bovine erythrocytes in 1% D-mannose, and possessed either colonization factor I or colonization factor II. No other colonization factors were identif...

This study investigated the adjuvant potential of W/O/W multiple emulsions and microemulsions, comparing them with traditional aluminum hydroxide and oil-in-water emulsion adjuvants against bluetongue vaccine (BTV). Local inflammatory reactions were assessed in rabbits by measuring the temperature of the animals and the skin thickness at the site of application. Antibodies titers were determine...

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

Highly active and stable MoS2/carbon hierarchical spheres with abundant active edge sites were fabricated by a simple micro-emulsion procedure where PVP was used as the carbon source, and carbon disulfide as the sulfur source and oil phase in micro-emulsion to control the morphology of MoS2. Hierarchical spheres of MoS2/carbon with a diameter of ca. 500 nm were obtained and characterized by sca...

Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oil-water interface, has been discovered a century ago, while being extensively studied in recent decades. Substituting solid particles for traditional surfactants, Pickering emulsions are more stable against coalescence and can obtain many useful properties. Besides, they are more biocompatible when solid par...

The aim of current research was to develop a water-in-oil emulsion containing grape seed extract for application in cosmeceuticals. Finally grinded dried grape seeds powder was extracted with hydro alcoholic mixture. Emulsions consisting of different concentrations of cetyl dimethicone (Abile EM90), the nonionic emulsifier, liquid paraffin as oily phase and water as aqueous phase were developed...

The objective of this study is to evaluate the emulsifier role in the synthesis of Iron Polyaniline nanocomposite by in-situ oxidative polymerization of aniline and reduction of Iron ions into Fe nanoparticles. The polymerization of aniline was carried out in the presence of FeCl as oxidizing agent. During the reaction 3 aniline monomers undergo oxidation and form polyaniline (PANI) whereas the...
