Class III Semaphorins (SEMA3) comprise a family of chemokines that have been implicated as negative regulators of axonal guidance, angiogenesis and tumor progression. It has been demonstrated previously that one SEMA3, SEMA3F, may have therapeutic potential in the treatment of cancer. When transfected with SEMA3F, the highly metastatic human melanoma cell line A375SM was found to exhibit a high...

Land cover, vegetation green leaf area index (LAI) and the fraction of incident photosynthetically active radiation absorbed by vegetation (FPAR) govern the exchange of energy, momentum and mass (water and carbon dioxide, for example) between the Earth’s surface and the atmosphere. These variables are operationally derived from measurements of the Multiangle Imaging SpectroRadiometer (MISR) abo...

متن کاملBoston medicine, before and after.
The Boston health care war had really stepped up at the end of winter. The hospitals were competing furiously for us to be their patients. Their ads boasted: “Individual Care/Global Impact,” “Human First,” “Exceptional Care Without Exception,” “World-Class Care Where You Live,” and “Everything Possible.” They told us we should choose them because they were big, because they were small, because ...
متن کاملInstrumental Variables Regression with Measurement Errors and Multicollinearity in Instruments
In this paper we obtain a consistent estimator when there exist some measurement errors and multicollinearity in the instrumental variables in a two stage least square estimation of parameters. We investigate the asymptotic distribution of the proposed estimator and discuss its properties using some theoretical proofs and a simulation study. A real numerical application is also provided for mor...
