The properties of taurocholate–lecithin powder (SIF Powder) and the biorelevant media FeSSIF and FaSSIF prepared from the powder were investigated using various techniques. The powder is stable and shows no change in the physical or chemical characteristics for at least 12 months in the original container stored at 2–8 °C. FeSSIF and FaSSIF were stable with respect to hydrolysis for at least 48...

The purpose of this study was to evaluate the pharmacokinetic behavior of florfenicol spray-dried nanosuspersion after oral administration to rabbits and to compare its oral bioavailability characteristics to that of a known soluble powder. Florfenicol spray-dried nanosuspersion was produced by high pressure homogenization followed by spray drying. Plasma concentrations were determined by HPLC....

A near infrared (NIR) method able to directly quantify the active content in pharmaceutical powder blends used for manufacturing meloxicam tablets, without any sample preparation, was developed and fully validated. To develop calibration models for the assay of meloxicam in powder blends for tableting, the NIR reflectance spectra of different meloxicam powder blends prepared according to a cali...

This paper reports the beneficial effect of twice daily ingestion (a table spoonful) of dried Kigelia africana fruit powder in the management of Polycystic Ovary Syndrome (PCOS) in two patients. Both patients had the classical triad of Amenorrhoea, acne and hirsutism. The two were 25 years old and 22 years old spinsters respectively. The ultrasonography was suggestive only in the latter; unfort...

Orthopedic components, such as the acetabular cup in total hip joint replacement, can be fabricated using porous metals, such as titanium, and a number of processes, such as selective laser melting. The issue of how to effectively remove loose powder from the pores (residual powder) of such components has not been addressed in the literature. In this work, we investigated the feasibility of two...

Peel powder and juice of fresh pomegranate (Punica granatum) were utilized to prepare cookies as sources of antioxidants, along with the other common ingredients, in the present study. The components were added in different proportions during the cookie preparation and their rheological, sensory and antioxidant properties were evaluated. Chemical composition (moisture, protein, carbohydrate and...

Extracts from mango (Mangifera indica Linn.) cultivar Chok-Anan seed kernels were studied as active substances, since they are known as a good source of phenolic antioxidants with metal chelating and tyrosinase inhibitory activities. Response surface methodology (RSM) was used to investigate the effect of a combination of polysaccharides selected from gum arabic, maltodextrin and alginate on dr...

Gale (1) and Epps (2) have reported the properties of an enzyme obtained from various strains of Streptococcus faecalis which decarboxylates tyrosine and dihydroxyphenylalanine. Both of these authors reported that the enzyme preparations, whether made by washing the whole organism, by drying the cells with acetone, or by further purification procedures, were specific to the above two amino acid...

According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...
