BACKGROUND Pancreatoduodenectomy (PD) for pancreatic cancer is very challenging to many surgeons. Information regarding the advantage of using the Da Vinci robotic system over conventional open surgery for PD is rare. Therefore, a comparison of the outcomes of PD performed using the Da Vinci robotic system with outcomes using open surgery was conducted. (More)
The mood stabilizers lithium and valproic acid (VPA) are traditionally used to treat bipolar disorder (BD), a severe mental illness arising from complex interactions between genes and environment that drive deficits in cellular plasticity and resiliency. The therapeutic potential of these drugs in other central nervous system diseases is also gaining(More)
Huperzine A, a reversible and selective acetylcholinesterase (AChE) inhibitor, has been reported to display neuroprotective properties. The present study investigated the protective effects of huperzine A in a rat model of transient focal cerebral ischemia created by middle cerebral artery occlusion (MCAO). Huperzine A (0.1 mg/kg), administrated(More)
BACKGROUND AND PURPOSE The migratory efficiency of mesenchymal stem cells (MSC) toward cerebral infarct after transplantation is limited. Valproate (VPA) and lithium enhance in vitro migration of MSC by upregulating CXC chemokine receptor 4 and matrix metalloproteinase-9, respectively. Ability of VPA and lithium to promote MSC homing and to improve(More)
Valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, is known to protect against cerebral ischemia. The effects of VPA on blood-brain barrier (BBB) disruption were investigated in rats subjected to transient middle cerebral artery occlusion (MCAO). Postischemic VPA treatment remarkably attenuated MCAO-induced BBB disruption and brain edema.(More)
BACKGROUND AND PURPOSE Enhanced angiogenesis facilitates neurovascular remodeling processes and promotes brain functional recovery after stroke. Previous studies from our laboratory demonstrated that valproate (VPA), a histone deacetylase inhibitor, protects against experimental brain ischemia. The present study investigated whether VPA could enhance(More)
Mesenchymal stem cells (MSCs) show high potential for the therapy of several human diseases; however, the effectiveness of MSC transplantation has been hampered by the relatively poor migratory capacity of these cells toward disease target sites. This study investigated whether treatment of MSCs with two mood stabilizers-valproic acid (VPA) and(More)
This study is to investigate the effects of huperzine A on memory deficits, neuronal damage and neurotrophic factors production after transient cerebral ischemia and reperfusion in mice, as well as the potential downstream signaling pathway. Bilateral common carotid occlusion (BCCAo) combined with systemic hypotension induced severe memory deficits in a(More)
Although traumatic brain injury (TBI) is recognized as one of the leading causes of death from trauma to the central nervous system (CNS), no known treatment effectively mitigates its effects. Lithium, a primary drug for the treatment of bipolar disorder, has been known to have neuroprotective effects in various neurodegenerative conditions such as stroke.(More)
Recently, optical interconnects have been proposed for ultra-high bandwidth and low latency inter/intra-chip communication in multiprocessor systems-on-chip (MPSoCs). These optical interconnects employ the microresonators (MRs) to direct/detect the optical signal. However, utilized MRs suffer from intrinsic crosstalk noise and power loss, degrading the(More)
