BACKGROUND N-butylidenephthalide (BP) exhibits antitumor effect in a variety of cancer cell lines. The objective of this study was to obtain additional insights into the mechanisms involved in BP induced cell death in human prostate cancer cells. METHODS/PRINCIPAL FINDINGS Two human prostate cancer cell lines, PC-3 and LNCaP, were treated with BP, and(More)
BACKGROUND The efficacy and feasibility of bilateral subthalamic deep brain stimulation (STN-DBS) for Parkinson's disease (PD) under general anesthesia (GA) has not been evaluated. OBJECTIVE We compared the outcome of patients under GA with those who were operated on under local anesthesia (LA). MATERIAL AND METHODS Thirty-three patients were assigned(More)
The natural compound n-butylidenephthalide (BP), which is isolated from the chloroform extract of Angelica sinensis, has been investigated for its antitumoral effects on glioblastoma multiform (GBM) brain tumors both in vitro and in vivo. To determine the mechanism of BP-induced growth arrest and apoptosis, we examined BP-induced changes in gene expression(More)
Episodic cessation of airflow during sleep in patients with sleep apnea syndrome results in intermittent hypoxia (IH). Our aim was to investigate the effects of IH on cerebellar granule cells and to identify the mechanism of IH-induced cell death. Cerebellar granule cells were freshly prepared from neonatal Sprague-Dawley rats. IH was created by culturing(More)
BACKGROUND Colorectal cancer (CRC), which has become especially prevalent in developed countries, is currently the third highest cause of cancer mortality in Taiwan. Mutation of the adenomatous polyposis coli (APC) gene, a tumour suppressor, is thought to be an early event in colorectal tumourigenesis. To date, however, no large-scale screening for APC gene(More)
Tanshinone IIA (Tan-IIA), one of the major lipophilic components isolated from the root of Salviae Miltiorrhizae, has been found to exhibit anticancer activity in various cancer cells. We have demonstrated that Tan-IIA induces apoptosis in several human cancer cells through caspase- and mitochondria-dependent pathways. Here we explored the anticancer effect(More)
BACKGROUND Angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphisms have been associated with acute coronary syndrome (ACS); however, several controversial results have also been found in different studied populations. This hospital-based, emergency room, case-control study in Taiwan retrospectively investigated 111 ACS patients, and(More)
Human adipose-derived stem cells (huADSC) were generated from fat tissue of a 65-year-old male donor. Flow cytometry and reverse transcription polymerase chain reaction (RT-PCR) analyses indicated that the huADSC express neural cell proteins (MAP2, GFAP, nestin and β-III tubulin), neurotrophic growth factors (BDNF and GDNF), and the chemotactic factor CXCR4(More)
Sleep apnea syndrome, characterized by intermittent hypoxia (IH), is linked with increased oxidative stress. This study investigates the mechanisms underlying IH and the effects of IH-induced oxidative stress on cerebellar astrocytes. Rat primary cerebellar astrocytes were kept in an incubator with an oscillating O2 concentration between 20% and 5% every 30(More)
Few rejuvenation and antiaging markers are used to evaluate food supplements. We measured three markers in peripheral blood to evaluate the antiaging effects of a food supplement containing placental extract. Samples were evaluated for CD34(+) cells, insulin-like growth factor 1 (IGF1), and telomerase activity, which are all markers related to aging. To(More)
