Automated seizure diagnosis system based on feature extraction and channel selection using EEG signals.

Seizure is an abnormal electrical activity of the brain. Neurologists can diagnose the seizure using several methods such as neurological examination, blood tests, computerized tomography (CT), magnetic resonance imaging (MRI) and electroencephalogram (EEG). Medical data, such as the EEG signal, usually includes a number of features and attributes that do not contains important information.

Prepubertal IGF-1 and Possible Relation with Physical Features of Growth and Type 1 Diabetes Mellitus.

Background: T1DM is considered as the most common chronic metabolic autoimmune disorder in childhood and adolescence as well as in the early adulthood. It appears frequently during 12- 13 years of age with distinctive features like immune-mediated chronic damage of pancreatic β-cells, leading eventually to partial, or mostly, absolute insulin deficiency. Insulin-like growth factor 1 (IGF-1) is a polypeptide consisting of 70 amino acids with insulin-like chemical structure.

Comparison of central venous oxygen saturation and mixed venous oxygen saturation during liver transplantation.

Central venous catheterisation is commonly performed during major surgery and intensive care, and it would be useful if central venous oxygen saturation could function as a surrogate for mixed venous oxygen saturation. We studied 50 patients undergoing living related liver transplantation. Blood samples were taken simultaneously from central venous and pulmonary artery catheters at nine time points during the pre-anhepatic, anhepatic, and postanhepatic phases.

Osmoregulation of taurine transporter function and expression in retinal pigment epithelial, ganglion, and müller cells.

Purpose: To determine whether taurine transporter (TauT) activity and expression are regulated by hyperosmolarity in RPE, ganglion, and Müller cells.

Methods: Uptake of taurine was measured in ARPE-19 cells cultured in DMEM-F12 medium without or with the addition of 50 mM NaCl or 100 mM mannitol. The kinetics of the transport were analyzed.

Analysis of sigma receptor (sigmaR1) expression in retinal ganglion cells cultured under hyperglycemic conditions and in diabetic mice.

The type 1 sigma receptor (sigmaR1) is a nonopiate and nonphencyclidine binding site that has numerous pharmacological and physiological functions. In some studies, agonists for sigmaR1 have been shown to afford neuroprotection against overstimulation of the NMDA receptor. sigmaR1 expression has been demonstrated recently in retinal ganglion cells (RGC).
