BACKGROUND After the recent cloning of light-sensitive ion channels and their expression in mammalian cells, a new field, optogenetics, emerged in neuroscience, allowing for precise perturbations of neural circuits by light. However, functionality of optogenetic tools has not been fully explored outside neuroscience, and a nonviral, nonembryogenesis-based(More)
BACKGROUND AND OBJECTIVES Intrahepatic biliary cystadenoma and biliary cystadenocarcinoma are extremely rare neoplasms of the liver. They share similar radiological characteristics, and the clinicopathological features are poorly defined. We aim to provide an algorithm for preoperative differentiation of the two diseases. METHODS Patients who underwent(More)
BACKGROUND Biological pacemakers (BPM) implanted in canine left bundle branch function competitively with electronic pacemakers (EPM). We hypothesized that BPM engineered with the use of mE324A mutant murine HCN2 (mHCN2) genes would improve function over mHCN2 and that BPM/EPM tandems confer advantage over either approach alone. METHODS AND RESULTS In(More)
BACKGROUND Many studies have already reported encouraging results in the prophylactic therapy of migraine by acupuncture, but there seems to be a lack of high quality randomized controlled trials from China. We design and perform a randomized controlled clinical trial to evaluate the efficacy of acupuncture compared with flunarizine in the prophylactic(More)
BACKGROUND Stroke is one of the leading causes of death and disability in China. Current treatments for stroke are limited and achieve no optimal effect. Acupuncture is widely used in the treatment of stroke and in improving the quality of life for patients in China. In most previous clinical studies, the effects of acupuncture have been diverse, and few(More)
A novel molecularly imprinted polymer (MIP) based on hydrophobic CdSe quantum dots (QDs) was synthesized using a one-pot room-temperature reverse microemulsion polymerization, and this polymer was applied as a molecular recognition element to construct a ractopamine (RAC) optosensor. Here, hydrophobic CdSe QDs were first introduced to the hydrophilic(More)
This work prepared a novel ionic liquid stabilized molecularly imprinted optosensing material based on quantum dots (QDs) and graphene oxide (GO) composites using a one-step polymerization for highly selective and sensitive specific recognition of vitamin E (VE). Here, GO was first introduced to the molecularly imprinted polymer (MIP) because of its(More)
A novel dual-function material was synthesized by anchoring a molecularly imprinted polymer (MIP) layer on CdTe/ZnS quantum dots (QDs) using a sol-gel with surface imprinting. The material exhibited highly selective and sensitive determination of ractopamine (RAC) through spectrofluorometry and solid-phase extraction (SPE) coupled with high performance(More)
A novel optosensing system based on quantum dots (QDs)-labeled on the surface of a molecularly imprinted polymer (MIP) was developed for turn-off fluorescence sensing of dicyandiamide (DCD). The QDs were modified with silica to covalently adhere to the MIP surface, which resulted in a higher fluorescence quantum yield than MIP-coated QDs. Under optimal(More)
The similarities and differences of eight vegetable oils produced in China were investigated in terms of their fatty acid, sterol, and tocopherol compositions and subsequent data processing by hierarchical clustering analysis and principal component analysis. The lipid profiles, acquired by analytical techniques tailored to each lipid class, revealed great(More)
