This paper suggests a beat detection method for ballistocardiogram (BCG) from an unconstrained cardiac signal monitoring devices. A fiducial peak point of BCG is an I-J-K complex which corresponds with ventricle contraction and Electrocardiogram (ECG) QRS complex. The goal of the method is extraction of J peak without ECG synchronization. The detection method is based on a "template matching" rule evaluated using a correlation function in a local moving-window procedure. The total beat detection

Among the blood laboratory test results during CPR of OHCA patients, pH and potassium levels were observed as independent factors associated with survival to hospital discharge, and pH level was considered as an independent factor related to neurological recovery.

The rate and number of adequate CCs were significantly lower with the CO-CPR than with the ST-CPR after 2 and 6 minutes, respectively, and performer fatigue was higher with the CO-CPR than with the ST-CPR during 8 minutes of CPR.

Prevalence of CT and GN in female rape victims was introduced and it was higher than that in the general population. Even in the VIR group, it was high. CMV prevalence in the female genital tract was reported firstly.

Changes in microcirculation are believed to perform an important role after cardiac arrest. In particular, rheological changes in red blood cells (RBCs) have been observed during and after ischemic-reperfusion injury. Employing three-dimensional laser interferometric microscopy, we investigated three-dimensional shapes and deformability of RBCs during and after asphyxial cardiac arrest in rats at the individual cell level. Rat cardiac arrest was induced by asphyxia. Five rats were maintained for

The goal of this study was to determine how much the formation of tetanus antibody is influenced after a single injection of tetanus vaccine (Td) and the simultaneous injection of tetanus vaccine with tetanus immunoglobulin (TIG). All of the healthy adult volunteers were divided into two groups: group 1 (Td only) and group 2 (Td plus TIG). Two hundred thirty seven volunteers were enrolled. When the baseline antibody titer, gender and age were adjusted, the geometric mean titers (GMTs) of the tet
