Exposure of the N2-fixing cyanobacterium Anabaena BT2 to ultraviolet-B radiation (2.5 W m−2) for 30 min resulted in complete loss of nitrogenase activity but 100% cell killing occurred only after a 90-min exposure. Inactivation of nitrogenase activity was not specific to Anabaena BT2; other species also showed a similar effect. The time required for 100%(More)
Sturge-Weber syndrome is a heterogeneous neurocutaneous syndrome with facial and leptomeningeal angiomas, glaucoma, seizures, stroke-like episodes, and mental retardation. The authors critically evaluated the clinical manifestations, outcome, and natural history in 30 patients with Sturge-Weber syndrome followed up from January 1985 to May 2010. Of the(More)
 Purpose: The Bcl-2 family of proteins regulates a late step in the apoptosis pathway. Bcl-2 protein is believed to be involved in imparting resistance to programmed cell death or apoptosis induced by chemotherapeutic agents and radiation. The anti-apoptotic function of the Bcl-2 protein appears to be modulated by its ability to heterodimerize with other(More)
Sturge-Weber syndrome (SWS) is a rare, sporadic neurocutaneous syndrome characterized by a classical triad of facial port wine nevus, ipsilateral leptomeningeal angiomatosis (LAM) and glaucoma. The incidence of SWS is 1/50,000 live births, although it is more often underreported. The incidence of SWS without facial nevus is not known, although very few(More)
