Both total hip arthroplasty (THA) and total knee arthroplasty (TKA) are deemed to be highly successful and cost-effective procedures for relieving pain and improving function. However, some studies have reported better pain relief and functional improvement after THA (Int J Technol Assess Health Care. 1997 Fall;13[4]:575-88, and J Arthroplasty. 1995 Dec;10[6]:742-7). It is certainly possible th...

In vitro evaluation of antioxidant activities of Ganoderma applanatum showed significant inhibition of lipid peroxidation, and potent hydroxyl radical scavenging activity when compared with standard drug catechin. IC50 values of crude, boiled and ethanolic extracts of G. applanatum were 604.8, 624 and 267 microg/ml, respectively in case of hydroxyl radical scavenging activity, and 441, 520.5 an...

A very rapid and drastic microsome-dependent in vitro inactivation of the hydrocortisone-induced ornithine decarboxylase in rat liver was reported recently (M. F. Zuretti and E. Gravela, Biochim. Biophys. Acta. 742: 269-277, 1983). Present results show that ornithine decarboxylase from preneoplastic nodules and hepatomas, which have been induced in rats by N-2-fluorenylacetamide, is much more s...

To assess the current uptake of hepatitis B vaccine and attitudes towards immunization among accident and emergency practitioners in the UK, a postal survey was carried out. Questionnaires were sent to 742 members of the British Association for Accident and Emergency Medicine (BAEM). Four hundred and six (55%) replies were received. Of 351 respondents in career-grade posts 309 (88%) had receive...

We prove that both minimum and maximum traveling salesman problems on complete graphs with edge-distances 1 and 2 (denoted by min TSP12 and max TSP12, respectively) are approximable within 3/4. Based upon this result, we improve the standard approximation ratio known for maximum traveling salesman with distances 1 and 2 from 3/4 to 7/8. Finally, we prove that, for any 2 > 0, it is NP-hard to ap...
