To fully assess the role of VEGF-A in tumor angiogenesis, antibodies that can block all sources of vascular endothelial growth factor (VEGF) are desired. Selectively targeting tumor-derived VEGF overlooks the contribution of host stromal VEGF. Other strategies, such as targeting VEGF receptors directly or using receptor decoys, result in inhibiting not only(More)
Vascular endothelial growth factor (VEGF) is an essential regulator of normal and abnormal blood vessel growth. A monoclonal antibody (mAb) that targets VEGF suppresses tumor growth in murine cancer models and human patients. We investigated cellular and molecular events that mediate refractoriness of tumors to anti-angiogenic therapy. Inherent anti-VEGF(More)
Vascular endothelial growth factor (VEGF) is a principal regulator of blood vessel formation and haematopoiesis, but the mechanisms by which VEGF differentially regulates these processes have been elusive. Here we describe a regulatory loop by which VEGF controls survival of haematopoietic stem cells (HSCs). We observed a reduction in survival, colony(More)

We describe a complete hardware/software system, dubbed Universal Real-Time Navigational Assistance (URNA), which enables communication of relevant location-aware information to a blind person carrying a Bluetooth-enabled cell phone. Although URNA can be used for a number of different applications (e.g., an information kiosk at a shopping mall or public(More)
BACKGROUND Malignant peripheral nerve sheath tumor (MPNST) is biologically an aggressive tumor for which the treatment of choice is the surgery. We reviewed the clinical profile, diagnostic methods, treatment patterns, and outcome of twenty-four MPNST patients in this study. PATIENTS AND METHODS A retrospective analysis of 24 MPNST patients, treated from(More)
Inflammatory bowel disease (IBD) consists of Ulcerative colitis (UC) and Crohn’s disease (CD). These two conditions share many common features—diarrhea, bloody stools, weight loss, abdominal pain, fever and fatigue. Small intestinal bacterial overgrowth (SIBO) is frequent in patients with CD but it has not been studied in UC Indian patients. The study was(More)
BACKGROUND Atrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all-cause mortality may guide interventions.

Inflammatory myofibroblastic tumor is a biologically distinct neoplasm of intermediate grade, which can affect every possible tissue of the human body. It is a 'masquerading tumor' as the presenting complaints vary with the affected site. Occurrence of this tumor as an orbital mass is rare and is challenging for both the clinician as well as the(More)
