Syncope and Cardiac Tamponade: Multimodality Imaging of Primary Cardiac Lymphoma.

Primary cardiac lymphoma (PCL) is among the rarest heart neoplasms. Its estimated incidence is about 1%-2% among primary cardiac tumor and 0.5% of extranodal lymphoma.

pKC modulates integrin expression that contributes to fibrotic changes in irradiated thyroid tissue.

Aim: We hypothesized that radiation-induced fibrosis was, in part, a result of altered signal transduction that directly modulates integrin expression and may indirectly affect the extracellular matrix (ECM). Major focus was given on protein kinase C (pKC).

Materials And Methods: Rat FRTL-5 and primary thyroid cells were exposed to proton radiation (5 and 10 Gy).

The effect of genetic background and dose on non-targeted effects of radiation.

Purpose: This work investigates the hypothesis that genetic background plays a significant role in the signalling mechanisms underlying induction and perpetuation of genomic instability following radiation exposure.

Materials And Methods: Bone marrow from two strains of mice (CBA and C57) were exposed to a range of X-ray doses (0, 0.01, 0.
