Congenital pulmonary airway malformations (CPAMs) are a heterogeneous group of hamartomatous cystic and noncystic lung lesions that result from early airway maldevelopment. Usually they are distinguished according to Stocker's classification in type 0, 1, 2, 3 and 4. We present the case of a 2 weeks old baby who was admitted to hospital with RDS symptoms and left pleural effusion: X rays and CT were suggestive for a pulmonary cystic lesion with pleural complications.

Objectives. To retrospectively compare the results of the MRIA (magnetic resonance index of activity) with a modified MRIA (mMRIA), which was calculated excluding from MRIA formula the data of relative contrast enhancement (RCE). Materials and Methods.

To characterize the cellular and molecular effects of these hadrons, we performed dose-response and time-course experiments by exposing different cell lines (PC3, Ca301D, MCF7) to increasing doses of protons and examining them with FACS, RT-PCR, and electron spin resonance (ESR). Irradiation with a dose of 10 Gy of a 26,7 Mev proton beam altered cell structures such as membranes, caused DNA double strand breaks, and significantly increased intracellular levels of hydroxyl ions, are active oxygen species (ROS).

Bradykinin, a mediator known for its proinflammatory action, is able to induce cytokine production and contractility in fibroblast cultures.
Objectives: In this study the ability of bradykinin to drive fibroblast into a myofibroblast phenotype at the cellular and molecular level was evaluated.
