PROBLEM: Question: Does maraviroc concentrate in the cervicovaginal fluid and vaginal tissue of HIV-negative women?
Answer: Higher maraviroc exposure in the female genital tract provides a pharmacologic basis for further evaluation of chemokine receptor 5 antagonists in HIV infection prophylaxis. This is the first study to report antiretroviral VT concentrations, CVF protein binding, and CVF terminal elimination.

SOLUTION: yes

PROBLEM: Question: Is fractional urinary excretion of IgG the most powerful predictor of renoprotection by ACE inhibitors in IgA nephropathy?
Answer: Renoprotection by ACEi is a multifactorial phenomenon: the best predictor of renoprotection is FEIgG, a marker of disruption of glomerular barrier to proteins; renoprotection depends not only on ability to reduce proteinuria, but probably also on antiinflammatory and antifibrotic activity.

SOLUTION: yes

PROBLEM: Question: Are leg muscle reflexes mediated by cutaneous A-beta fibres normal during gait in reflex sympathetic dystrophy?
Answer: In the acute phase of RSD of the lower extremity there is no evidence for abnormal A-beta fibre-mediated reflexes or for defective regulation of such reflexes. This finding has implications for both the theory on RSD pathophysiology and RSD models, which are based on abnormal functioning of A-beta fibres.

SOLUTION:
yes
