Matrix tablets comprising of a blend of cellulose acetate butyrate (CAB) or cellulose acetate propionate (CAP) and alpha-lactose monohydrate were prepared by direct compression to control the release of diclofenac sodium. Tablet formulations containing CAP75000 or CAB50-54 exhibited highest extents, but lowest onsets of plastic deformation and lowest release rates in buffer medium, while tablet...

In recent decades, physical techniques based on the application of magnetic fields (MF) have been developed in agricultural sector with favorable results plant germination and growth. The main objective this study is to determine effects treatment seeds following species Salvia officinalis L. Calendula Groups were exposed MF 125 mT for different times, other groups subjected pretreatment others...

Some diabetic patients--particularly those with nausea and vomiting--frequently have evidence of delayed gastric emptying while other diabetic patients may in fact exhibit accelerated gastric emptying. Whether the presence or absence of symptoms of upper gastrointestinal dysfunction correlated with objective measures of gastric emptying in insulin dependent diabetic subjects was investigated. T...

BACKGROUND (13)C-Acetate labeled meals are widely used to determine meal emptying by means of analyzing resulting (13)CO(2) exhalation dynamics. In contrast to the underlying metabolic processes, only few (13)C breath test meal emptying studies have focused on intragastric processes that may alter (13)CO(2) exhalation. This work assessed the effect of enhanced gastric secretion on the reliabili...

The study on the effect of polymer concentration in vitro drug release profile revealed that there is a change parameters (t50, t80, and MDT) with concentration. Fraction HPMC K4M, K 100 M, Ethyl Cellulose were required to be 15, 10, 7 mg respectively for designing optimized batch F7. rate Colchicine decreased proportionally an increase ethyl K100 M. Also high amount K4M leads less initial sust...

A hypothesis was tested that the in ovo injection of biological buffers may reinforce the buffering capacity of albumen, thereby withstanding the increase in albumen pH during storage and improving hatchability and chick quality in long-term stored eggs. Hatching eggs (n = 2,420) were randomly assigned to 11 treatment groups (4 replicates of 55 eggs each) and injected (d 1) with distilled water...

This paper describes the development and evaluation of a method for measuring the vapor pressure distribution and volatility-dependent mass spectrum of organic aerosol particles using a thermodenuder-particle beam mass spectrometer. The method is well suited for use with the widely used Aerodyne Aerosol Mass Spectrometer (AMS) and other quantitative aerosol mass spectrometers. The data that can...

We used soluble, C-fixing antibody/dsDNA IC to investigate immune complex (IC) handling and erythrocyte (E)-to-phagocyte transfer in chimpanzees. IC bound efficiently to chimpanzee E in vitro and showed minimal release with further in vitro incubation in the presence of serum in EDTA (less than or equal to 15% within 1 h). These IC also bound rapidly to E in vivo (70-80% binding within 1 min) a...
