F (t)=E0 (0) ??For any single epitope, the probability of it fusing with the target cell it is bound to before it is disabled by a bound antibody is equal to f (?). The probability of this fusion being prevented by an antibody is pb 1{f (?) ??The probability pb of disabling a gp41 trimer in the pre-hairpin intermediate may depend on both A, the mAb concentration and on N, the number of gp41 trime

S did not count as first-line failures. The decision to switch to a second-line bPI-containing regimen for first-line failure was based on clinical criteria in both groups (new/ recurrent WHO 4 event (per-protocol); or single or multiple WHO 3 events at clinician discretion), or confirmed CD4,100 cells/ mm3 on ART (,50 cells/mm3 before July 2006) for LCM. Switching was discouraged before 48 weeks

Hments between virus and cell and disabling these is sufficient to prevent infection. enhanced susceptibility to MPER neutralizing antibodies could be a result of prolonged exposure of the intermediate state during viral entry [25]. Although numerous studies have determined rate constants for the binding of 4E10 and 2F5 to peptide epitopes in solution and peptides conjugated to liposomes [2,4,10,1

TementInformed written consent was obtained from each participant and the trial was approved by ethics committees in Uganda, Zimbabwe and the UK. DART was a randomised controlled trial comparing routine Laboratory (CD4 and toxicity) plus Clinical Monitoring (LCM) with CDM in 3316 symptomatic (WHO stage 2/3/4) HIV?infected ART-naive adults initiating combination ART with in Uganda/Zimbabwe CD4,200

At screening, weeks 4 and 12, then 12-weekly. All results from LCM participants were returned to clinicians, whereas for CDM participants CD4 counts were measured but never returned. For all participants, if clinically indicated, diagnostic and other tests could be requested (excluding CD4/total lymphocytes in CDM) and concomitant medications prescribed. VLs were not performed in real-time, but we

Sutezolid (formerly PNU100480, Pfizer) and AZD5847 (AstraZeneca) are new oxazolidinones in phase 2 development for TB [50]. Sutezolid is largely metabolized by flavin monooxygenases to sulfoxide and sulfone derivatives [51]. The sulfoxide metabolite is present in plasma at five to seven times the

Rt' algorithm, and 93 (81?6 ) with the `Xpert/LF-LAM' algorithm (Table 2). For a cohort of 10 000 HIV patients in Uganda, the `Smear/LF-LAM' algorithm was estimated to lead to 3191 DALY's-averted (782?446) and 271 (67?70) TB deaths averted compared with the `Smear' algorihm. By contrast, `Xpert' implementation was estimated to avert 4757 DALY's (1471?0964) compared with the `Smear' algorithm. LF-
