Abstract:Constitutively activated forms of ALK caused by genetic aberrations have been shown to cause an expanding variety of human cancers. The FDA recently approved the Pfizer drug Xalkori (crizotinib) to treat patients with non-small cell lung cancers (NSCLC) that express ALK. Numerous other… more
Abstract:Lung cancer is the main cause of cancer mortality worldwide with 80% non-small cell lung cancer (NSCLC) in type and mainly driven by three mutually exclusive oncogenes, EGFR, KRAS and ALK (collectively between 30-60% of all NSCLC cases). Oncogenic driverssuch as ROS1 and RET fusions and DEPDC1… more
Abstract:Utilizing directed energy weapons effectively in an offensive situation or determining the level of protection needed for defense requires the ability to select the proper DEW source characteristics and method of delivery based on the target, any shielding and the desired effect. This is an… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
