... following the start of ther- apy [1-3]. These reports consider that the period of high mortality lasts about three to six months after start of ther- apy. To analyze this type of survival data, acknowledge- ment ... period after the first three months, is particularly good, but the survival estimate still underestimates the mortality rate in the later period after initiatio...

By the end of 2006, 2,350 patients had been initiated on ART at Tete ... implementation over a realistic timeframe, and attention to monitoring at all levels.

... proportion of C> ;T transitions (70%) and a hot spot of mutations at codon 81 (p.Pro81Ser) [9]. Altogether these data suggest a role of TCE or its metabolites in these mutational events. To explore ... UMD-VHL database of somatic VHL mutations in RCC tumours. In fact, this somatic mutation pattern suspected to be associated with TCE exposures is much closer to the germline mutati...

... walk. This supports the notion that PF tests, especially those that measure mobility-related activities, correlate better with the HRQoL dimensions that relate to the physical component, although ... correlations between the PF tests also showed that the functional reach test, the TUG, and the 6-min walk could be grouped; this reflects the fact that they all relate to mobility-related a...

... (3.7) together with A > 0 and B >0. Next, we prove that φ r (x)= F n (x, r) F n ( x, r − 1 ) is increasing with respect to x i (i=1,2, ,n). By the symmetry of j r (x) with respect to x i (i=1, ...
