BACKGROUND Whole brain radiation therapy (WBRT) reduces local recurrence in patients after surgical resection of brain metastases without improving overall survival. Involved field radiation therapy (IFRT) has been used at our center to avoid delayed neurotoxicity associated with WBRT in well-selected patients with surgically resected single brain(More)
The anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) monoclonal antibody ipilimumab has been shown to improve survival in patients with metastatic non-CNS melanoma. The purpose of this study was to investigate the efficacy of CTLA-4 inhibitors in the treatment of metastatic melanoma with limited brain metastases treated with stereotactic(More)
Previously we have shown that our routine portal imaging (PI) of the craniofacial region in pediatric brain tumor patients contributed an additional 2%-3% of the prescribed dose and up to 200 cGy to the planning target volume (PTV) and nearby organs at risk (OARs). The purpose of this study is to quantify the reduction in dose to PTV and OARs from portal(More)
Alzheimer's disease (AD) is the most common cause of dementia affecting the elderly. Treatment for effective cure of this complex neurodegenerative disease does not yet exist. In AD, otherwise soluble, monomeric form of amyloid beta (Abeta) peptide converts into toxic, fibrillar form rich in beta-sheet content. Several immunological approaches that prevent(More)
Brain metastases in malignant melanoma carries a poor prognosis with minimal response to any therapy. The purpose of this pilot analysis was to find the effectiveness of vemurafenib, an oral BRAF inhibitor, and radiation therapy in V600 mutated melanoma with brain metastases. BRAF mutation status of the melanoma patients was determined by real-time PCR(More)
Inhibition of Acetylcholinesterase (AChE) is still considered as the main therapeutic strategy against Alzheimer's disease (AD). Many plant derived phytochemicals have shown AChE inhibitory activity in addition to the currently approved drugs for AD. In the present study, methanolic extracts of 20 plants used in Indian Ayurvedic system of medicine for(More)
