BACKGROUND Preoperative imaging is widely used and extremely helpful in hepatobiliary surgery. However, transfer of preoperative data to a intraoperative situation is very difficult. Surgeons need intraoperative anatomical information using imaging data for safe and precise operation in the field of hepatobiliary surgery. We have developed a new system for(More)
BACKGROUND In malignant hepatic neoplasm, anatomic resection could improve survival and limit complications from hepatectomy. Our purpose was to develop an intraoperative method for identifying segment and subsegment of the liver with high-sensitivity near-infrared fluorescence imaging. METHODS The subjects were 35 patients with hepatic malignant liver(More)
Minocycline has been shown previously to have beneficial effects against ischemia in rats as well as neuroprotective properties against excitotoxic damage in vitro, nigral cell loss via 6-hydroxydopamine, and to prolong the life-span of transgenic mouse models of Huntington's disease (HD) and amyotrophic lateral sclerosis (ALS). We investigated whether(More)
Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus (EBV) associated malignant tumor. Recently, cidofovir, an anti-viral drug which is an acyclic nucleoside analogue, has been reported to have an anti-tumor potential. Two patients with NPC, who had previously received multi-round therapy, were treated with cidofovir. Cidofovir was topically injected in(More)
Our past work has shown that the C-terminal fragment of amyloid precursor protein (APP) translocated to the nucleus in neurons destined for delayed excitotoxic degeneration. To test whether nuclear APP fragments also play a role in the progressive loss of dopaminergic (DA) substantia nigra compacta (SNc) neurons, we performed unilateral medial forebrain(More)
Transplantation of isolated hepatocytes has been proposed to compensate for essential functions lacking in liver failure or for genetic defects that alter a specific liver metabolic pathway. Hepatocyte utilization for these purposes would be facilitated with a reliable, reproducible, and effective method of long-term hepatocyte storage. We have recently(More)
OBJECTIVE Matrix metalloproteinase-1 (MMP-1) and interleukin-8 (IL-8) play an important role in cancer development and metastasis. There is a single nucleotide polymorphism (SNP) located in the promoter region of MMP-1 and IL-8 that regulates gene expression. MMP-1 -1607 2G/2G and IL-8 -251 A/A genotypes enhance transcriptional activity and may be(More)
Focal microglial activation and progressive dopaminergic neurodegeneration in substantia nigra compacta (SNc) have characterized Parkinson's disease (PD). We have hypothesized that the microglial response may be provoked by molecular signals from chronically stressed SNc neurons. To test whether amyloid precursor protein (APP) could serve as such a signal,(More)
Recent studies have demonstrated that the transplantation of bone marrow cells following diabetes induced by streptozotocin can support the recovery of pancreatic b-cell mass and a partial reversal of hyperglycemia. To address this issue, we examined whether the c-Met/hepatocyte growth factor (HGF) signaling pathway was involved in the recovery of b-cell(More)
