AIM Laparoscopic surgery, especially laparoscopic rectal surgery, for colorectal cancer has been developed considerably. However, due to relatively complicated anatomy and high requirements for surgery techniques, laparoscopic right colectomy develops relatively slowly. This study was designed to compare the outcomes of laparoscopic right hemicolectomy(More)
Microbial pathogens have been selected for the capacity to evade or manipulate host responses in order to survive after infection. Chlamydia, an obligate intracellular pathogen and the causative agent for many human diseases, can escape T lymphocyte immune recognition by degrading host transcription factors required for major histocompatibility complex(More)
Epidemiological and experimental studies have suggested that high dietary intake of fats is associated with cognitive decline and a significantly increased risk of dementia. Since oxidative stress and inflammation have been speculated to be critical mechanisms underlying neurodegenerative diseases, we hypothesized that a high fat (HF) diet might induce(More)
A possible way to improve the economic efficacy of acetone-butanol-ethanol fermentation is to increase the butanol ratio by eliminating the production of other by-products, such as acetone. The acetoacetate decarboxylase gene (adc) in the hyperbutanol-producing industrial strain Clostridium acetobutylicum EA 2018 was disrupted using TargeTron technology.(More)
1 Endothelin-1 (ET-1), an endothelium-derived vasoactive peptide, participates in the regulation of endothelial function through mechanisms that are not fully elucidated. This study examined the impact of ET-1 on oxidative stress, apoptosis and cell proliferation in human umbilical vein endothelial cells (HUVEC). HUVECs were challenged for 24 h with ET-1(More)
Cellular hypertrophy is regulated by coordinated pro- and antigrowth machineries. Foxo transcription factors initiate an atrophy-related gene program to counter hypertrophic growth. This study was designed to evaluate the role of Akt, the forkhead transcription factor Foxo3a, and atrophy genes muscle-specific RING finger (MuRF)-1 and atrogin-1 in cardiac(More)
Insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) can stimulate apoptosis and inhibit cell proliferation directly and independently of binding IGFs or indirectly by forming complexes with IGF-I and IGF-II that prevent them from activating the IGF-I receptor to stimulate cell survival and proliferation. To date, IGF-independent actions only have(More)
Obesity is associated with oxidative stress and mitochondrial and myocardial dysfunction, although interaction among which remains elusive. This study was designed to evaluate the impact of the free radical scavenger metallothionein on high-fat diet-induced myocardial, intracellular Ca(2+), and mitochondrial dysfunction. FVB and metallothionein transgenic(More)
BACKGROUND Minimal access techniques have gained wide acceptance in surgical practice, but the role of laparoscopic pancreaticoduodenectomy is still controversial. Laparoscopic pancreaticoduodenectomy has seldom been described. In this report, we assessed the feasibility and safety of laparoscopic pancreaticoduodenectomy for ductal adenocarcinoma of the(More)
Head-mounted display (HM) units are used in various industries, but they have been tried only recently in surgery. In this study, we evaluated whether a commercially available HMD would improve or impede a laparoscopic task—in this case, suturing. Six participants performed a total of 120 laparoscopic suture knots in an experimental model. The Olympus(More)
