Pigs and humans have shared influenza A viruses (IAV) since at least 1918, and many interspecies transmission events have been documented since that time. However, despite this interplay, relatively little is known regarding IAV circulating in swine around the world compared with the avian and human knowledge base. This gap in knowledge impedes our(More)
CYP2E1 knockout mice (cyp2e1-/-) were used to investigate the involvement of CYP2E1 in the development of carbon tetrachloride (CCl4)-induced hepatotoxicity. Male cyp2e1-/- and wild-type (cyp2e1+/+) mice were given a single i.p. injection of 1 ml/kg (= 1.59 g/kg) CCl4 and 24 h later liver injury was assessed by elevations of serum alanine aminotransferase(More)
We performed a prospective study of microlaparoscopic direct entry in the left upper quadrant (LUQ) to determine the efficacy of this technique and the incidence and site of anterior abdominal wall adhesions in high-risk patients. Direct insertion of the MiniPort introducer was successful with 1 attempt in 16 patients and in 2 attempts with 1 patient.(More)
A review of the studies of the caries prevalence and periodontal health of patients with cleft lip and palate (CLP) revealed that only five investigations of caries prevalence in CLP patients included children. One reported that CLP children did not have a higher caries prevalence in the permanent dentition, whereas more recent studies have reported a(More)
Serum copper and caeruloplasmin concentrations are elevated in various carcinomas, but it is not known whether the rise in serum copper is due to elevation of caeruloplasmin alone or whether it is also due to the elevation of 'free' copper. We therefore determined ultrafiltrable copper to answer this question. Serum ultrafiltrate was prepared using the(More)
OBJECTIVE To compare the surgical managements for ectopic pregnancy. METHODS In a retrospective analysis, we examined the trend of surgical procedures and the results of different management in 149 patients. RESULTS The change from laparotomy to laparoscopic treatment was significant. The success rates of salpingostomy and salpingectomy under(More)
Several studies have shown that plasma/serum copper and ceruloplasmin concentrations are increased in various carcinomas. We determined serum concentrations of ceruloplasmin and plasma copper concentration to evaluate the clinical usefulness of these tests in patients with cervical carcinomas. There was a significantly higher ceruloplasmin concentration in(More)
Hong Kong has a subtropical climate and an influenza seasonality lying approximately mid-way (March-June) between those of the Northern (November-March) and Southern (June-September) hemispheres. Respiratory syncytial virus (RSV) shares a similar seasonality to that of influenza in Hong Kong and is another important respiratory infection of childhood. Daily(More)
The enzyme-linked immunosorbent assay (ELISA) was successfully applied to detect IgE antibodies against parasitic antigens by using an additional antibody layer to attain an amplification effect. The sera of 18 Gurkha patients with clinical manifestations of acute trichinosis and 35 Chinese with other parasitic infections were tested for antibodies to(More)
Sera from 2,499 randomly selected Chinese inhabitants of Hong Kong were tested for the presence of Toxoplasma gondii antibodies using the indirect fluorescent antibody test. The over-all prevalence was 9.8%. The prevalence was significantly higher in the 10 to 19 and 30 to 39 year age group and the highest level of titres was found in the 20 to 29 group.(More)
