Osteosarcoma (OS) is the most common primary malignancy of bone. It is responsible for 80-85% of the primary bone tumors affecting dogs and it is characterized by aggressive and invasive behavior, with a high metastatic potential. Several studies on cancer and related tumorigenesis, show an involvement of the mechanisms of programmed cell death and cell survival. Many signals seem to be involved in the related mechanism of autophagy and in particular, our interest is focused on the expression of a family of Bcl-2 that seems to be involved either in the control of biomolecular mechanisms like autophagy and apoptosis. In this study we investigated the expression of Bcl-2 in different cases of spontaneous canine osteosarcoma and the related preliminary results are described. We found Bcl-2 activity was increased in OS tissue compared to normal bone tissue. These results suggested that Bcl-2 activity may play an important role in the formation of OS and as a diagnostic for neoplastic activity. However, further research is needed to confirm the role of Bcl-2 activity in OS in canines.

Objective: Cognitive impairment (CI) is highly prevalent in subarachnoid hemorrhage (SAH) patients. The phosphatidylinositol 3-kinase (PI3K)/AKT pathway plays a critical role in neuronal survival in a variety of central nervous system injuries. This study aimed to determine whether electroacupuncture (EA) at and LI20 ameliorates SAH-CI in a rat model and to examine whether it modulates the PI3K/AKT pathway by administering a PI3K inhibitor (LY294002) versus dimethyl sulfoxide (DMSO) vehicle.
