BACKGROUND The prolonged effectiveness of antiretroviral therapy (ART) in a developing country is not well established. METHODS An observational database was established at the HIV clinic of the Almenara Hospital in Lima, Peru in 1996. All 564 initially antiretroviral-naive HIV-infected persons (mean CD4 count of 91 cells/mm3) who received combination ART(More)
BACKGROUND Although human herpesvirus 6 (HHV-6) is known to reactivate during hematopoietic stem cell transplantation (HSCT), the clinical significance of this finding is controversial. METHODS We used a quantitative PCR test for HHV-6 to assay plasma samples prospectively collected from a cohort of 110 allogeneic HSCT recipients to evaluate the clinical(More)
Medium-chain-length polyhydroxyalkanoates (MCL-PHAs), which have constituents with a typical chain length of C6-C14, are polyesters that are synthesized and accumulated in a wide variety of Gram-negative bacteria, mainly pseudomonads. These biopolyesters are promising materials for various applications because they have useful mechanical properties and are(More)
User comments are one of the common online resources that reflect users’ evaluative opinions about multimedia contents. The words used in user comments provide many clues about the users and about what they like or dislike. In this paper, we propose a novel query expansion method that utilizes user comments in order to consider user’s different preferences(More)
Varicella-zoster virus (VZV) disease occurs in 30% of allogeneic hematopoietic cell transplant recipients who had a history of VZV infection. A safe and effective prevention strategy has not been established. In a double-blind controlled trial, 77 hematopoietic cell transplant recipients at risk for VZV reactivation were randomized to acyclovir 800 mg twice(More)
We conducted a 12-year retrospective study to determine the effects that the community respiratory-virus species and the localization of respiratory-tract virus infection have on severe airflow decline, a serious and fatal complication occurring after hematopoietic cell transplantation (HCT). Of 132 HCT recipients with respiratory-tract virus infection(More)
18F-labeling of proteins and peptides is important for positron emission tomography (PET). Although there are many methods for the labeling of proteins with (18)F, most of these are characterized by complicated procedures or low yields. Here, we report a novel and simple method which includes the preparation of [18F]fluorobenzaldehyde ([18F]FBA) and(More)
PURPOSE The objective of the present study was to rank the most common liver staging systems according to prognostic accuracy in patients with unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). MATERIALS AND METHODS Survival of 172 consecutive patients with unresectable HCC treated with TACE was correlated(More)
We performed a case-control study to determine the association of BK plasma viremia with hemorrhagic cystitis (HC) in hematopoietic cell transplant (HCT) recipients. Thirty cases of HC (14 of which occurred after platelet engraftment with documented BK viruria [BK-HC]) were compared with matched controls. Weekly plasma samples were tested for BK virus DNA(More)
We describe the synthesis of 2'-[(18)F]fluoroflumazenil (FFMZ), which differs from the typically used [(18)F]fluoroethylflumazenil (FEFMZ) for benzodiazepine receptor imaging. For one-pot one-step labeling, the precursors, 2'-tosyloxyflumazenil (TFMZ) and 2'-mesyloxyflumazenil (MFMZ), were synthesized in three steps. The precursors were successfully labeled(More)
