Can a CT scan detect a lung infection?
While no diagnostic imaging, including CT can identify infectious organisms, changes in the lung physiology caused by infection are readily identifiable. Respiratory viruses, bacteria, fungi, TB and parasites each may be associated with image findings characterized for the particular infection. READ MORE

Data provided by the National Library of Medicine- Pharmocologic inhibitors of the mitogen activated protein kinase cascade have the potential to interact with ionizing radiation exposure to induce cell death in carcinoma cells by multiple mechanisms.
- Inhibitors of MEK1/2 interact with UCN-01 to induce apoptosis and reduce colony formation in mammary and prostate carcinoma cells.
- Stress and radiation-induced activation of multiple intracellular signaling pathways.
- Epidermal growth factor and ionizing radiation up-regulate the DNA repair genes XRCC1 and ERCC1 in DU145 and LNCaP prostate carcinoma through MAPK signaling.
- MAPK pathways in radiation responses.
- Radiation-stimulated ERK1/2 and JNK1/2 signaling can promote cell cycle progression in human colon cancer cells.
- H-RAS V12-induced radioresistance in HCT116 colon carcinoma cells is heregulin dependent.
- Activated forms of H-RAS and K-RAS differentially regulate membrane association of PI3K, PDK-1, and AKT and the effect of therapeutic kinase inhibitors on cell survival.
- Screening for suicide among juvenile delinquents: reliability and validity evidence for the Suicide Screening Inventory (SSI).
- Human chorionic gonadotropin modulates prostate cancer cell survival after irradiation or HMG CoA reductase inhibitor treatment.

- Survival benefit for early hormone ablation in biochemically recurrent prostate cancer.
- Low-dose BBR3610 toxicity in colon cancer cells is p53-independent and enhanced by inhibition of epidermal growth factor receptor (ERBB1)-phosphatidyl inositol 3 kinase signaling.
- Transient exposure of carcinoma cells to RAS/MEK inhibitors and UCN-01 causes cell death in vitro and in vivo.
