Abstract: A system and method are provided for in-line processes of blending butane into gasoline streams, and for blending butane into a gasoline stream at any point along a petroleum pipeline. The invention additionally provides a method for measuring the vapor pressure and vapor to liquid ratio of the gasoline, both upstream and downstream of the blending operation, as well as the sulfur content of the butane entering the blending operation. The blending operation can be controlled to ensure that the blended gasoline meets EPA requirements for vapor pressure and sulfur content of gasoline. The invention further provides a method for accessing and monitoring the operation off-site.

Abstract: Methods and kits for diagnosing and treating cerebrovascular events, and for defining the time and anatomical location of an event, are provided based on the detection and quantification of bound or total and unbound NR2 peptides in biological fluids. The methods are optionally performed in conjunction with neurological scoring and neuroimaging, and are directed to risk assessment, prognosis, diagnosis and treatment of TIA and stroke on an emergency basis in the emergency room.

Abstract: A methods, kits and compositions for diagnosing a central nervous system disorder, particularly transient ischemic attack or stroke, comprising measuring the level of NR2A and/or NR2B NMDA receptor or fragment thereof, in a biological sample from a human subject, and optionally measuring other biomarkers such as homocysteine and glutamate. The method is particularly useful for identifying individuals that are at risk for stroke, and for diagnosing stroke in an emergency room setting.
