BACKGROUND Overtreatment of catheter-associated bacteriuria is a quality and safety problem, despite the availability of evidence-based guidelines. Little is known about how guidelines-based knowledge is integrated into clinicians' mental models for diagnosing catheter-associated urinary tract infection (CA-UTI). The objectives of this research were to(More)
Neurocysticercosis (NCC), a helminth infection of the brain, is a major cause of seizures. The mediators responsible for seizures in NCC are unknown, and their management remains controversial. Substance P (SP) is a neuropeptide produced by neurons, endothelial cells and immunocytes. The current studies examined the hypothesis that SP mediates seizures in(More)
Myocarditis is an important cause of heart failure in adolescents and young adults and is caused, most commonly, by viral infections. Viral myocarditis is characterized by cardiac inflammation and cardiomyocyte necrosis. The molecular pathogenesis of viral myocarditis is incomplete and specific therapies are not available. Proinflammatory cytokines such as(More)
Cryptosporidiosis, caused by Cryptosporidium, causes self-limited diarrhea in normal hosts but may cause life-threatening diarrhea in immunocompromised persons. Cryptosporidium-induced manifestations, including weight-loss and intestinal physiological alterations are not noted in adult immunocompetent mice. So far, studies that have been used to test the(More)
Acid phosphatase (E.C.3.1.3.2) in a giant cell bone tumor and a spleen infiltrated with hairy cells was extracted by citrate buffer and then by 0.3 mol/L NaCl. The cationic acid phosphatase in the crude extract was isolated by CM-cellulose chromatography, and further separated by high pressure liquid chromatography. The majority of the tartrate resistant(More)
Hematoxylin and eosin staining of rabbit eyes after YAG laser anterior capsulotomy showed amorphous substances at the anterior chamber angle. The amorphous substances were identified as fibrin by immunohistochemical methods. This finding indicated that the obstruction of aqueous humor flow by fibrin could be responsible for the elevation of intraocular(More)
Cysticercosis is an infection with larval cysts of the cestode Taenia solium. Through pathways that are incompletely understood, dying parasites initiate a granulomatous reaction that, in the brain, causes seizures. Substance P (SP), a neuropeptide involved in pain-transmission, contributes to inflammation and previously was detected in granulomas(More)
BACKGROUND Many hospitals are increasing surveillance for catheter-associated urinary tract infections, which requires documentation of urinary catheter device-days. However, device-days are usually obtained by chart review or nursing reports. The aim of this study was to demonstrate that chart review can provide accurate urinary catheter data compared with(More)
Cryptosporidiosis, caused by the protozoan parasite Cryptosporidium parvum, causes self-limited diarrhea in normal hosts but can cause life-threatening diarrhea for immunosuppressed patients. There is an urgent need for new drugs to treat this chronic disease. Cryptosporidium parvum infection is associated with intestinal structural and pathophysiologic(More)
Neurocysticercosis, caused by the cestode Taenia solium, is the most common parasitic infection of the human central nervous system that leads to seizures. Taenia crassiceps cysticercosis in mice is an experimental model for Taenia solium cysticercosis. Similar to the human infection, live parasites cause little or no granulomatous inflammation. Dying(More)
