Early and accurate detection of oncological disease is critical to the treatment and, ultimately, survival of patients suffering from cancer. In an effort to determine the accuracy of an integrated PET/CT scanner with more traditional diagnostic imaging methods for whole-body, malignant tumors, researchers in Essen, Germany, compared the imaging results of the integrated FDG-PET/CT with CT images alone, PET images alone, and CT and PET images viewed side-by-side.
The scientists theorized that the new technologically superior, dual-modality PET/CT would yield more accurate readings of tumor staging than previously used image capture methods. The German team presented their findings at the Society of Nuclear Medicine’s 51st Annual Meeting.
The study included 260 patients with a variety of oncological diseases. The patients underwent whole-body imaging, and the results of the four image sets--CT alone, PET alone, CT and PET viewed side by side, and integrated PET/CT--were evaluated by different reader teams according to the TNM (Tumor-Node-Metastasis) staging system. Histopathology and follow-up clinical assessment of the patients served as the baseline standard of reference.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
