The cleavage of carbon dioxide by the tungsten alkylidyne [CF3-ONO]W[triple bond, length as m-dash]CCtBu(THF)2 (1) {where CF3-ONO = (MeC6H3[C-(CF3)2O])2N3-}, is reported. Splitting of CO2 yields the tungsten oxo ketene complex [CF3-ONO]W(O){(CH3)3CC[double bond, length as m-dash]C[double bond, length as m-dash]O} (6). The proposed pathway occurs through initial cycloaddition of W[triple bond, l...
during a period of 10 months from may to february 1995, 120 children (72 girls, 48 boys) with an age range of 4-16 years (mean age 10.87, s.d.±2.7) with chronic abdominal pain who had an abnormal endoscopy (gastroduodenal mucosal defect) and positive urease test were treated for h. pylori. patients were treated randomly with either metronidazole and amoxicillin (double therapy, group a) or metr...
The Coleman integral is a p-adic line integral. Double Coleman integrals on elliptic curves appear in Kim’s nonabelian Chabauty method, the first numerical examples of which were given by the author, Kedlaya, and Kim [3]. This paper describes the algorithms used to produce those examples, as well as techniques to compute higher iterated integrals on hyperelliptic curves, building on previous jo...
BETWEEN September 10, 1995, and September 20, 1997, a total of 208 adult patients undergoing their first or second cadaveric renal transplantation alone were randomized to receive tacrolimus!prednisone (n = 106) or tacrolimus/prednisone/mycophenolate mofetil (n = 102), without induction antilymphocyte antibody therapy. The mean recipient age was 50.8 ::!:: 13.7 years (range 19 to 84). Thirty-on...
OBJECTIVES Resistance to pyrimethamine in Plasmodium falciparum is conferred by mutations in the gene encoding dihydrofolate reductase (DHFR). It is known that DHFR double mutants have evolved independently in multiple geographic areas, whereas the triple mutant prevalent in Africa appears to have originated in south-east Asia. In this study, we investigated whether other triple mutants may hav...
