DC-based tumor vaccine research has largely focused on enhancing DC maturation/costimulation and antigen presentation in order to break tolerance against self tumor-associated antigens. DC immunization can activate autoreactive T cells but rarely causes autoimmune pathologies, indicating that self tolerance at the host level is still maintained in the(More)
A 40-year-old male liver allograft recipient had neurological dysfunction and renal failure while his cyclosporin blood levels were in the therapeutic range; these features recurred on rechallenge. The hypothesis that this toxic effect might have resulted from abnormal metabolism of cyclosporin by liver cytochrome P-450 IIIA was investigated with the(More)
Near-infrared (NIR) fluorescence imaging clinical studies have been reported in the literature with six different devices that employ various doses of indocyanine green (ICG) as a non-specific contrast agent. To date, clinical applications range from (i) angiography, intraoperative assessment of vessel patency, and tumor/metastasis delineation following(More)
Although values for cardiac output in the newborn infant have been reported previously, the methods utilized have been invasive. To assess if cardiac output could be determined noninvasively in the neonate, we measured mean ascending aortic blood flow velocity (VAo) in well newborns using a portable 5MHz, range gated, pulsed Doppler velocity meter.(More)
p53-binding protein-1 (53BP1) is phosphorylated in response to DNA damage and rapidly relocalizes to presumptive sites of DNA damage along with Mre11 and the phosphorylated histone 2A variant, gamma-H2AX. 53BP1 associates with the BRCA1 tumor suppressor, and knock-down experiments with small interfering RNA have revealed a role for the protein in the(More)
Mutations in gene RASA1 have been historically associated with capillary malformation-arteriovenous malformation, but sporadic reports of lymphatic involvement have yet to be investigated in detail. To investigate the impact of RASA1 mutations in the lymphatic system, we performed investigational near-infrared fluorescence lymphatic imaging and confirmatory(More)
We studied left ventricular (LV) cardiac output as estimated by ascending aorta blood flow (QAo) longitudinally in 31 healthy infants from birth through the first year of life using noninvasive pulsed Doppler ultrasound technique. The temporal mean ascending aortic blood flow velocity (VAo) was measured with a 5-MHz pulsed Doppler velocimeter and on line(More)
OBJECTIVE Investigational, near-infrared fluorescence (NIRF) lymphatic imaging was used to assess lymphatic architecture and contractile function in participants diagnosed with Dercum's disease, a rare, poorly understood disorder characterized by painful lipomas in subcutaneous adipose tissues. METHODS After informed consent and as part of an FDA-approved(More)
Lymphedema affects up to 50% of all breast cancer survivors. Management with pneumatic compression devices (PCDs) is controversial, owing to the lack of methods to directly assess benefit. This pilot study employed an investigational, near-infrared (NIR) fluorescence imaging technique to evaluate lymphatic response to PCD therapy in normal control and(More)
Mice deficient in the enzyme adenosine deaminase (ADA) have small lymphoid organs that contain reduced numbers of peripheral lymphocytes, and they are immunodeficient. We investigated B cell deficiency in ADA-deficient mice and found that B cell development in the bone marrow was normal. However, spleens were markedly smaller, their architecture was(More)
