Direct bird-to-human transmission, with the production of severe respiratory disease and human mortality, is unique to the Hong Kong-origin H5N1 highly pathogenic avian influenza (HPAI) virus, which was originally isolated from a disease outbreak in chickens. The pathobiology of the A/chicken/Hong Kong/220/97 (H5N1) (HK/220) HPAI virus was investigated in(More)
Objective. The objectives of this paper were to determine the rate of misclassification of smoking and nonsmoking status by self-reports and saliva cotinine of pregnant women participating in a smoking cessation trial, determine the relationship of the number of cigarettes smoked per day and saliva cotinine, and examine whether misclassification was due to(More)
Since the 1997 H5N1 influenza virus outbreak in humans and poultry in Hong Kong, the emergence of closely related viruses in poultry has raised concerns that additional zoonotic transmissions of influenza viruses from poultry to humans may occur. In May 2001, an avian H5N1 influenza A virus was isolated from duck meat that had been imported to South Korea(More)
The H5N1 type A influenza viruses that emerged in Hong Kong in 1997 are a unique lineage of type A influenza viruses with the capacity to transmit directly from chickens to humans and produce significant disease and mortality in both of these hosts. The objective of this study was to ascertain the susceptibility of emus (Dramaius novaehollandiae), domestic(More)
This investigation assessed the ability of the zoonotic A/chicken/Hong Kong/220/97 (chicken/Hong Kong) (H5N1) highly pathogenic avian influenza virus to infect and cause disease in zebra finches (Taeniopygia guttata), house finches (Carpodacus mexicanus), house sparrows (Passer domesticus), European starlings (Sternus vulgaris), and budgerigars(More)
BACKGROUND With the use of optical coherence tomography (OCT), alterations of the reflectance characteristics of everolimus-eluting bioresorbable vascular scaffold (BVS) struts have been reported in humans. In the absence of histology, the interpretation of the appearances of the struts by OCT remains speculative. We therefore report OCT findings with(More)
This study examined the experiences of 360 women receiving bilateral breast augmentation with Dow Corning's Silastic MSI (textured) or Silastic II (smooth) gel-filled mammary implants. Before surgery, the women completed a quantitative assessment of their surgical expectations and concerns. At 6, 12, and 24 months postoperatively, they rated their(More)
Case reports have raised questions about an increased risk of connective tissue diseases (CTDs) among women with breast implants. From the reviews of more than 2,600 manuscripts, abstracts, and dissertations, this meta-analysis included 13 epidemiology studies that provided a relative risk (RR) estimate for the possible association between breast implants(More)
An evaluation of refrigeration (7°C) to prevent falsely high plasma or serum zinc concentrations owing to elapsed time between blood collection and centrifugation was performed. At room temperature (23°C), both plasma and serum zinc concentrations increased significantly, if blood samples were stored uncentrifuged. Plasma zinc concentrations increased 6.3%(More)
This investigation detailed the clinical disease, gross and histologic lesions, and distribution of viral antigen in juvenile laughing gulls (Larus atricilla) intranasally inoculated with either the A/tern/South Africa/61 (H5N3) (tern/SA) influenza virus or the A/chicken/Hong Kong/220/97 (H5N1) (chicken/HK) influenza virus, which are both highly pathogenic(More)
