We have developed a high-information-content fingerprinting (HICF) system for bacterial artificial chromosome (BAC) clones using a Type IIS restriction endonuclease, HgaI, paired with a Type II restriction endonuclease, RsaI. In the method described, unknown five-base overhangs generated with HgaI are partially or fully sequenced by modified fluorescent(More)
The effect of anoxia on roots of soybean (Glycine max [L.] Merr., variety ;Williams') was studied at various levels and the results compared to those from previously studied species. While alcohol dehydrogenase (ADH) activity is induced in a manner similar to other plant species, other aspects of the anaerobic response are unique to soybean. A variety of(More)
The structure of the human hepatic triglyceride lipase gene was determined from multiple cosmid clones. All the exons, exon-intron junctions, and 845 bp of the 5' and 254 bp of the 3' flanking DNA were sequenced. Comparison of the exon sequences to three previously published cDNA sequences revealed differences in the sequence of the codons for residues 133,(More)
Sequences of the recA genes of the highly divergent thermopholic eubacteria Thermus aquaticus (and Thermus thermophilus), Thermotoga maritima, and Aquifex pyrophilus were determined from fragments derived by polymerase chain reaction (PCR) with degenerate primers and from inverse PCR products obtained using unique primers based on the fragment sequences.(More)
Transversus abdominis plane block provides postoperative analgesia following abdominal surgery by targeting thoracolumbar nerves between the internal oblique and transversus abdominis muscles. Posterior and subcostal approaches using ultrasound guidance have been described. However there have been inconsistent results in relation to the extent of the(More)
Genomic clones containing human delta-aminolevulinate dehydratase (ALAD), the second enzyme in the heme pathway, were isolated, and the entire sequence was determined in both orientations (15,913 bp; GenBank Accession No. X64467). The gene contained two alternative noncoding exons, 1A and 1B, and 11 coding exons, 2-12. Ten Alu-repetitive elements were(More)
OBJECTIVE To investigate whether the pleth variability index (PVI), derived noninvasively from a pulse oximeter probe, would predict fluid responsiveness in patients undergoing noncardiac surgeries. DESIGN A clinical, prospective, observational study. SETTING Operating room of a tertiary care hospital. PARTICIPANTS Twenty-nine adult patients(More)
Palliative care for end-stage renal disease (ESRD) is developing in Hong Kong. This is the first local study to explore the symptom burden and quality of life (QOL) of ESRD patients on chronic dialysis and palliative care. This was a prospective cross-sectional study conducted on ESRD patients in a hospital in Hong Kong from January 2006 to April 2007. Data(More)
BACKGROUND AND OBJECTIVES Ultrasound needle visualization is a fundamental skill required for competency in ultrasound-guided regional anesthesia. The primary objective of this study using a cadaver model was to quantify the number of procedures that novices need to perform before competency, using a predefined dynamic scoring system was achieved in(More)
This study compared the cardiac output responses to haemodynamic interventions as measured by three minimally invasive monitors (Oesophageal Doppler Monitor the VigileoFlotrac and the LiDCOrapid) to the responses measured concurrently using thermodilution, in cardiac surgical patients. The study also assessed the precision and bias of these monitors in(More)
