DMS is rare (0.22%) and almost exclusively found in females in routine echocardiography. The prevalence of DMS increases with aging to 2.5% in patients >90 years of age, and DMS is often associated with aortic valve stenosis.

A variety of precursor minifoci were noted to be selectively bound to bile ducts and ductules in rat liver, which may be of physiologic significance in excretion of carcinogens during initiation.

We present a case of a rare combination of ventricular septal defect and atrial septal aneurysm (ASA) with a patent foramen ovale (PFO) in a 57-year-old female. She was referred to our hospital for the treatment of irregular palpitation and exertional shortness of breath. Two-dimensional transesophageal echocardiography (2D-TEE) with color Doppler imaging demonstrated an ASA with two lines of shunt flows. Three-dimensional transesophageal echocardiography (3D-TEE) could clearly visualize the morphology of the PFO in the surgeon's view and demonstrated a crescent-shaped opening of the PFO. 3D-TEE appears to be a more accurate modality than 2D-TEE for the assessment of PFO.

Social Medical Corporation Kojinkai has established multiple hospitals in the eastern region of Hokkaido Prefecture. Each facility is using our wide area network and the electronic medical record system. Clinical laboratory technologists of various levels of experience have also been performing carotid ultrasonography at each facility. Carotid ultrasonography has been reported using the unified report system and criteria of our facilities. We discuss here whether differences exist between each of our facilities in the results of carotid ultrasonography. We performed photographic surveillance to determine the inter-rater agreement of clinical laboratory technologists. Weighted kappa values between clinical laboratory technologists were good. As a result, the quality control of test results for carotid ultrasonography was considered to be maintained, and was enabled using the unified report by seeing the same pictures in real time and allowing discussion between facilities. The wide area network with unified reporting was useful for quality control of carotid ultrasonography.Keywords: quality control; wide area network; unified report; carotid ultrasonography (Received December 25, 2013

Integrins have become a target for novel therapeutic strategies against malignant gliomas. Cilengitide, a synthetic Arg-Gly-Asp (RGD)-motif peptide, interferes with ligand binding to avb3 and avb5 integrins and is currently investigated in clinical trials. Integrins may also be involved in the activation of transforming growth factor (TGF)-b, a mediator of invasiveness and immune escape of glioma cells. Using flow cytometry, we demonstrate that the target integrins of cilengitide are expressed not only in glioblastoma blood vessels, but also by tumor cells. After exposure of glioma cells to cilengitide, we noticed reduced phosphorylation of Smad2 in most glioma cell lines, including stem-like glioma cells. Phophorylation of Smad2, but not cilengitide-induced detachment, is rescued by addition of recombinant TGF-b. Administration of cilengitide to glioma cells results in reduced TGF-b-mediated reporter gene activity. Furthermore, exposure to cilengitide leads to decreased TGF-b 1 and TGF-b 2 mRNA and protein expression. These effects are mimicked by blocking av, b3 or b5 antibodies or by silencing of integrins av, b3, b5 or b8 using RNA interference. Treatment of mice bearing experimental LN-308 glioma xenografts with cilengitide results in reduced pSmad2 levels. Taken together, cilengitide may exert anti-invasive and immune stimulatory activity in human glioblastoma patients by its anti-TGF-b properties.
