EXECUTIVE SUMMARY Aspergillus species have emerged as an important cause of life-threatening infections in immunocompromised patients. This expanding population is composed of patients with prolonged neutropenia, advanced HIV infection , and inherited immunodeficiency and patients who have undergone allogeneic hematopoietic stem cell transplantation (HSCT)(More)
BACKGROUND Invasive fungal infections (IFIs) are a major cause of morbidity and mortality among organ transplant recipients. Multicenter prospective surveillance data to determine disease burden and secular trends are lacking. METHODS The Transplant-Associated Infection Surveillance Network (TRANSNET) is a consortium of 23 US transplant centers, including(More)
192-IgG saporin is an anti-neuronal immunotoxin that combines the 192 monoclonal antibody to the p75 neurotrophin receptor found on terminals and cell bodies of neurons in the cholinergic basal forebrain with the ribosome-inactivating protein saporin. Injection of 100, 237.5 or 375 ng of 192-saporin into the medial septum produced dose-related deficits in a(More)
192-IgG-Saporin is an anti-neuronal immunotoxin that combines the 192 monoclonal antibody to the p75 neurotrophin receptor found on terminals and cell bodies of neurons in the cholinergic basal forebrain with the ribosome-inactivating protein saporin. Bilateral intraventricular injection of the 192-saporin produced a variety of dose-related behavioral,(More)
BACKGROUND The incidence and epidemiology of invasive fungal infections (IFIs), a leading cause of death among hematopoeitic stem cell transplant (HSCT) recipients, are derived mainly from single-institution retrospective studies. METHODS The Transplant Associated Infections Surveillance Network, a network of 23 US transplant centers, prospectively(More)
Rats were trained for fifteen sessions in an automated eight arm radial maze prior to treatment with 6 mg/kg trimethyltin chloride. This compound is a neurotoxicant which primarily damages the limbic system, in particular pyramidal cells in the CA3 region of the hippocampus. Following treatment the animals exhibited a marked and persistent impairment of(More)
Trimethyltin is a neurotoxic organometal which produces neuronal damage in several limbic regions including the hippocampus, amygdala and the pyriform cortex. One administration of trimethyltin (5, 6 or 7 mg/kg) twenty one days prior to passive avoidance conditioning produced an impairment of retention when animals were tested 24 hours after training. Rats(More)
(NIST) promotes the U.S. economy and public welfare by providing technical leadership for the Nation's measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of concept implementations, and technical analysis to advance the development and productive use of information technology. ITL's responsibilities include the(More)
Trimethyltin (TMT) chloride, administered to adult male Long-Evans hooded rats, produced a unique and distinctive behavioral syndrome consisting of spontaneous seizures, tail mutilation, vocalization and hyperreactivity. The LD50 for TMT was weight dependent; in large rats (e.g., 450 g), 7 mg/kg TMT produced significant weight loss and lethality, whereas in(More)
Bilateral injection of 3.5 micrograms of colchicine into two levels of the dentate gyrus produced a selective loss of dentate granule cells and persistent behavioral effects in male Fischer rats. Histological analysis confirmed that this dosage of colchicine resulted in the selective loss of most granule cells in both superior and inferior blades of the(More)
