Extracts of mistletoe (Viscum album var. coloratum) have been used for several decades as an anticancer immunomodulating agent in clinical fields. However, the mechanism by which the plant extracts kill tumor cells has remained elusive. We investigated the direct effects of beta-galactoside- and N-acetyl-d-galactosamine-specific mistletoe lectin II in(More)
The promoter of the mouse inducible nitric oxide synthase (iNOS) has a putative octamer motif (ATGCAAAA) which exists 24 bp upstream from the TATA box and is mismatched at a single residue from the consensus octamer motif. To examine whether this site is involved in iNOS expression, we constructed various deletions and site-directed mutants of the iNOS(More)
Three cases of basal cell carcinoma (BCC) with extensive invasion are described. The first two patients had meningeal and cerebral involvement with exposure of their dural meninges following full thickness skull erosion. The third patient had bilateral orbital and optic nerve involvement resulting in complete blindness. All three patients subsequently died(More)
BACKGROUND The variable-stiffness colonoscope incorporates different degrees of stiffness of the insertion tube, which can be adjusted during the examination. Whether its use can lead to reduced procedure-related pain and sedative use is unknown. OBJECTIVE Our purpose was to compare the use of 3 types of colonoscope with different shaft stiffnesses in(More)
BACKGROUND A prospective randomized trial was conducted to compare the safety, effectiveness, and patient acceptance of patient-controlled sedation and intravenous sedation for colonoscopy in a group of elderly patients undergoing outpatient colonoscopy. METHODS One hundred patients over 65 years of age were recruited and randomized to patient-controlled(More)
A study of the incidence of skin cancer over a 14-year period in the North Humberside area of the U.K. indicates a steady rise in the numbers of the four most common types of skin cancer. A steep increase in the incidence of squamous cell carcinoma of the skin compared with that of internal squamous cell carcinoma was also detected. Our findings emphasize(More)
Fourteen cases of pyoderma gangrenosum were seen over a period of 24 years at the Hull Royal Infirmary Dermatology Department. Several associated conditions were found. Seven cases were associated with rheumatoid arthritis of which five were sero-positive, including one with Felty's syndrome. One case was associated with both ulcerative colitis and(More)
BACKGROUND A prospective randomized controlled trial was performed to test the hypotheses that music decreases the dose of sedative medication required for colonoscopy and that the combination of music and patient-controlled sedation improves patient acceptance of colonoscopy. METHODS One hundred sixty-five patients scheduled to undergo elective(More)
BACKGROUND AND PURPOSE Two-port laparoscopic cholecystectomy has been reported to be safe and feasible with a higher patient satisfaction score. However, it was technically difficult even in expert hands because of the small operating field. We have modified the operating telescope to achieve a wide field of view. PATIENTS AND METHODS Since September(More)
