Traumatic brain injury (TBI) is a leading cause of sustained impairment in military and civilian populations. However, mild (and some moderate) TBI can be difficult to diagnose because the injuries are often not detectable on conventional MRI or CT. Injured brain tissues in TBI patients generate abnormal low-frequency magnetic activity (ALFMA, peaked at 1-4(More)
PURPOSE Despite advances in the treatment of chronic lymphocytic leukemia (CLL), the disease remains incurable with standard therapies and relapse is inevitable. A growing body of evidence indicates that alterations in the adhesion properties of neoplastic cells play a pivotal role in the development and progression of CLL. EXPERIMENTAL DESIGN The(More)
The Werner and Bloom syndromes are caused by loss-of-function mutations in WRN and BLM, respectively, which encode the RecQ family DNA helicases WRN and BLM, respectively. Persons with Werner syndrome displays premature aging of the skin, vasculature, reproductive system, and bone, and those with Bloom syndrome display more limited features of aging,(More)
PURPOSE To provide the wound care practitioner with information about how chronic wound healing differs in the older adult population. TARGET AUDIENCE This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. OBJECTIVES After participating in this educational activity, the participant should be(More)
OBJECTIVE The approach to acute cognitive dysfunction varies among physicians, including intensivists. Physicians may differ in their labeling of cognitive abnormalities in critically ill patients. We aimed to survey: (a) what Canadian intensive care unit (ICU) physicians identify as "delirium"; (b) choices of non-pharmacological and pharmacological(More)
Human arylamine N-acetyltransferases (NAT) bioactivate arylamine and heterocyclic amine carcinogens present in red meat and tobacco products. As a result, factors that regulate expression of NATs have the potential to modulate cancer risk in individuals exposed to these classes of carcinogens. Because epidemiologic studies have implicated well-done meat(More)
To show the efficacy of an allogenic bone graft in elective foot surgery, the authors report on 39 consecutive procedures in which allograft was implanted in 26 patients during a 30-month period. These procedures were performed for a variety of conditions, including arthrodesis, segmental lengthening, and treatment of nonunion. Allograft material consisted(More)
With more than 5.5 million fractures and 1 million bone repair surgeries annually, bone graft plays a significant role in aiding fracture repair. In the United States alone, surgeons perform an estimated 500,000 to 600,000 bone grafting procedures annually. With the advent of possibilities from bone substitutes, growth factors, and stem cell research, the(More)
Chronic lymphocytic leukemia (CLL) is predominantly a disease of accumulation rather than rapid proliferation. To date, no cell lines exist, as CLL cells undergo rapid apoptosis when cultured in vitro, suggesting that a favorable in vivo microenvironment is required. To identify survival signals we cultured primary CLL peripheral blood mononuclear cells(More)
