Cocktail II

چکیده
Cocktail II (a further development of Cocktail) is an interactive tool for deriving programs from specifications. Instead of verifying a program after it was constructed, Cocktail II aids the goal oriented derivation of a program. First, the user provides a preand postcondition. Then, the gap between these conditions is filled by manually inserting statements, constructing the program step by step. The tool then computes the sub specifications of the new gaps, which can be manually refined further. Finally, when a precondition of a gap implies its postcondition, the gap can be closed. Cocktail II also provides support for constructing the required proof. The program is complete when all gaps are closed.

II . Passive Protection of ICR Mice with G Protein - specific MAbs Mortality
Immunization of mice and hamsters with a cocktail of mouse MAbs specific for rabies virus nucleocapsid protein and glycoprotein protected animals not only when challenged with a lethal dose of rabies virus after immunization, but also in postexposure situations. Hamsters treated with the MAb cocktail 3 h after virus inoculation were completely protected from lethal rabies virus infection, and 8...

متن کاملEvaluation of lentinan effects on cytochrome P450 activity in rats by a cocktail method
Objective(s): In this study, a cocktail of probe drugs was used to assess whether lentinan could influence the activities of rat enzymes CYP3A4, CYP2D6, CYP1A2, CYP2C19, and CYP2C9 in vivo. Materials and Methods: Fourteen days after intraperitoneal injection of lentinan, rats were given an oral dose of a cocktail solution containing phenacetin, tolbutamide, omeprazole, metoprolol, and midazolam...
متن کاملFormation of therapeutic phage cocktail and endolysin to highly multi-drug resistant Acinetobacter baumannii: in vitro and in vivo study
Objective(s): Phage therapy is a potential alternative treatment for infections caused by Acinetobacter baumannii, a significant nosocomial pathogen, which has evolved resistance to almost all conventional antimicrobial drugs in poor hygiene and conflicts areas such as Iraq. Materials and Methods: Bacteriophages were isolated to highly resistant isolates of A. baumannii to form therapeutic phag...
متن کاملSimultaneous Screening of Activities of Five Cytochrome P450 and Four Uridine 5'-Diphospho-glucuronosyltransferase Enzymes in Human Liver Microsomes Using Cocktail Incubation and Liquid Chromatography-Tandem Mass Spectrometry.
Cytochrome P450 (P450) and uridine 5'-diphospho-glucuronosyltransferase (UGT) are major metabolizing enzymes in the biotransformation of most drugs. Altered P450 and UGT activities are a potential cause of adverse drug-drug interaction. A method for the simultaneous evaluation of the activities of five P450s (CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A) and four UGTs (UGT1A1, UGT1A4, UGT1A9, and...
