Predictive value for mortality of left ventricular wall thickness in dilated cardiomyopathy.

Aims: The purpose of this study was to explore the predictive value of wall thickness measured by cardiac magnetic resonance (CMR) for all-cause mortality in dilated cardiomyopathy (DCM) patients.

Methods And Results: DCM patients who underwent CMR and completed the regular follow-up were included in this study. The left ventricular end-diastolic diameter (LVDd), left ventricular end-diastolic volume (LVEDV), left ventricular posterior wall thickness (PWT), interventricular septum thickness (IVST), left ventricular ejection fraction, and left ventricular mass (LVM) were measured by CMR.

Investigation of Tactile Perception Evoked by Ridged Texture Using ERP and Non-linear Methods.

The triangular ridged surface can improve the grip reliability of products, but the sharp edge of triangular ridge induces sharp and uncomfortable feeling. To study the effect of edge shape (sharp, round, and flat shape) of triangular ridges on brain activity during touching, electroencephalograph (EEG) signals during tactile perception were evaluated using event-related potentials (ERP) and non-linear analysis methods. The results showed that the early component of P100 and P200, and the late component of P300 were successfully induced during perceiving the ridged texture.

From finger friction to brain activation: Tactile perception of the roughness of gratings.

The formation of tactile perception is related to skin receptors and the cerebral cortex. In order to systematically study the tactile perception from finger friction to the brain response, a 32-channel Brain Products system and two tri-axial force sensors were used to obtain electroencephalograph (EEG) and friction signals during fingers exploring grating surfaces. A finite element finger model was established to analyze the stress changes of the skin receptors during tactile perception.

Imaging features of soft tissue epithelioid angiosarcoma in the lower extremity: A case report.

Epithelioid angiosarcomas are extremely rare malignant tumors formed from endothelial cells. The majority of studies reporting these tumors have been concerned with the clinical and pathological aspects, with limited reporting of radiological diagnosis. The aim of the present study was to provide a reference to improve understanding of diagnosis, treatment choice and prognosis assessment of epithelioid angiosarcoma.
