A method is described for the purification of the A substance in horse saliva, and additional observations on the chemical properties of the preparation are reported. The preparation isolated was found to be highly active serologically and it appears to be polysaccharide in nature.
The authors present an epizootiological analysis of viral haemorrhagic disease of rabbits in Poland. The biological, physical and chemical properties of virus isolates used for the production and control of the vaccine 'Cunivac' (produced in Poland) are also presented. The safety and efficacy of this vaccine are demonstrated. Laboratory experiments and large-scale field observations yielded sat...
Molecular modeling frequently constructs classification models for the prediction of two-class entities, such as compound bio(in)activity, chemical property (non)existence, protein (non)interaction, and so forth. The models are evaluated using well known metrics such as accuracy or true positive rates. However, these frequently used metrics applied to retrospective and/or artificially generated...
Some of the drugs have poor absorption because a narrow window in gastrointestinal tract (GIT). To improve such GIT, gastro-retentive drug delivery techniques play an important role. Diacerein is antirheumatic used for joint pain and arthritis. The expandable tablets were prepared to attain extended therapeutic action Diacerein. Expandable formulated prolong gastric retention, enhance bioavaila...
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
This paper deals with the characterization of pellets containing andrographolide in two parts. The first part deals with characterization of the pellets to ascertain the identity and integrity of andrographolide. Part two involves characterization of the pellets containing Andrographis paniculata extract (33.3%) prepared in the paper I for their micromeritic properties like Particle size, Parti...
BACKGROUND AND THE PURPOSE OF THE STUDY The purpose of the present investigation was to characterize, optimize and evaluate microballoons of Propranolol hydrochloride and to increase its boioavailability by increasing the retention time of the drug in the gastrointestinal tract. METHODS Propranolol hydrochloride-loaded microballoons were prepared by the non-aqueous O/O emulsion solvent diffus...
