Naphthalene is a nasal carcinogen, inducing respiratory adenomas in male and olfactory neuroblastomas in female rats, respectively. The reasons for the site and sex-specific tumorigenic response are unknown. Naphthalene is bioactivated to electrophilic metabolites; cytotoxicity followed by regenerative cell proliferation is likely involved in the(More)
The provision of physiotherapy services to guest nations by the host nation, Zimbabwe, at the sixth All Africa Games is examined. There was a high rate of pre-existing injury. Ice, the Cryocuff, and ultrasound were the most frequently used tools, and should be made available to physiotherapists at all multisport events. It is recommended that collection of(More)
The target site for inhaled vapor-induced injury often differs in mouth-breathing humans compared with nose-breathing rats, thus complicating the use of rat inhalation toxicity data for assessment of human risk. We sought to examine sensitivity of respiratory/transitional nasal (RTM) and tracheobronchial (TBM) mucosa to two electrophilic irritant vapors:(More)

BACKGROUND An estimated $8.1 billion (in 2004 dollars) is spent annually on total health care costs for the treatment of breast cancer in the United States. Breast cancer has traditionally been treated with intravenous (IV) cancer therapies that entail not only the drug acquisition cost, but additional costs of personnel time, supplies, and equipment used(More)
OBJECTIVES To describe the epidemiology of carbon monoxide (CO) poisoning in a defined population, identifying those at greatest risk from acute poisoning resulting in admission to hospital or death. METHODS A retrospective study with routinely collected information, set in the former West Midlands Regional Health Authority; population of 5.2 million. The(More)
Earlier studies reported a decline in September mortality in New York City and Budapest during years when Yom Kippur was in the interval September 28 through October 3, and fewer deaths among Californians with Jewish surnames during the week preceding Passover than during the week after Passover. These studies suggest that some Jews are able to postpone(More)
A designer looking at a drawing sometimes notices things not originally intended. Conversely, not all implications of a design action are considered before each depiction action is taken. This paper describes an approach to understanding and reproducing this behaviour based on a situated interaction with an external representation.
