BACKGROUND The aim of this study was to investigate whether a small dose of midazolam and lessening the propofol dosage could prevent cardiovascular change at tracheal intubation for induction in aged patients. METHODS Eighty patients over 65 years (ASA physical status 1, 2) scheduled for elective surgery received general anesthesia with remifentanil and(More)
BACKGROUND The microRNA (miRNA) pathway has emerged as one of the biologic pathways implicated in stem cell regulation. miRNA is a noncoding, single-stranded RNA consisting of 20-25 nucleotides that inhibits the protein production at the step of translation. The molecular effects of lidocaine and procaine on adipose stem cells were investigated by examining(More)
An 81-year-old male patient was scheduled for a laparoscopic cholecystectomy due to acute cholecystitis. About 50 minutes into the operation, the arterial blood pressure suddenly decreased and ventricular fibrillation appeared on the electrocardiography. The patient received cardiopulmonary resuscitation and recovered a normal vital sign. We suspected a(More)
BACKGROUND Unlike the right internal jugular vein (RIJV), there is a paucity of data regarding the effect of the Trendelenburg position on the left internal jugular vein (LIJV). The purpose of this study is to investigate the cross-sectional area (CSA) of the LIJV and RIJV and their response to the Trendelenburg position using two-dimensional ultrasound in(More)
BACKGROUND Inhalation anesthetics are an important factor for postoperative hepatic and renal dysfunction. In this regard, TIVA can reduce the risk of hepatic and renal dysfunction inherited to inhalation anesthetics. The present study was conducted to determine whether hepatic and renal functions differ after anesthesia with sevoflurane and propofol. (More)
BACKGROUND It was well-known that smoking affects the cardiovascular system, and remifentanil can suppress the sympathetic stimulations induced by tracheal intubation. The purpose of this study was to investigate whether there was any difference in the hemodynamic changes induced by tracheal intubation with using remifentanil between smokers and nonsmokers.(More)
BACKGROUND Survivin is thought to contribute to stem cell maintenance partly by a hypomethylation mechanism. This study attempted to elucidate the signal transduction pathway of adipocyte-derived stem cells (ASCs) by using a demethylating agent, 5-aza-2'-deoxycytidine (ADC), to analyze the survivin, MEK/ERK, c-Myc and p53 gene expression. METHODS(More)
Background: Several studies have indicated that a nerve injury enhances the expression of the voltage-gated calcium channel α2δ1 subunit (Cavα2δ1) in sensory neurons and the dorsal spinal cord. This study examined whether NMDA receptor activation is essential for Cavα2δ1-mediated tactile allodynia in Cavα2δ1 over-expressing transgenic mice and L5/6 spinal(More)
