Does post-Surgical Language Reorganization occur in Tumors of the Dominant and Non-Dominant Hemisphere?
Resection of gliomas in the dominant and in the non-dominant hemisphere induces postsurgical shifts and increase in language activation, indicating that infiltrating gliomas have a widespread influence on the language network. The dominant hemisphere gained most of the language activation irrespective of tumor localization, possibly reflecting recovery of pre-surgical tumor-induced suppression of these activations.
We conclude that adenosine levels in the systemic blood increase in patients in ischemic and nonischemic chronic heart failure. Because adenosine counteracts catecholamine-, renin-angiotensin-, and cytokine-induced cellular injury, increased adenosine levels may be endogenous compensatory mechanisms for heart failure.
