The endovascular treatment of patients with tiny, wide-necked aneurysms is technically challenging, due to the small volume for microcatheterization and coil stabilization inside the aneurysm sac. We performed a retrospective study to evaluate the feasibility, effectiveness, and safety of stent-assisted embolization for patients with ruptured, tiny,(More)
OBJECTIVE Blood blister-like aneurysms (BBAs) are unique due to their high risk of recurrent bleeding associated with their fragile neck. The best treatment for BBAs is still controversial. This paper sought to evaluate the safety and efficacy of stent-assisted coiling and subsequent overlapping stents (SAC+OS) in the treatment of BBAs. METHODS Fifteen(More)
Dengue virus (DENV) is a mosquito-borne virus that has four serotypes. Collection of serum from patients is time- and labor- consuming, and presents a high injury risk for infants and children. The genomic and serological diagnosis of imported dengue fever from a urine sample was used as a non-invasive diagnostic method in this study. A serum sample was(More)
Angiocentric glioma (AG) was recognized as a distinct clinicopathological tumor in 2007, but it is rarely reported. We report a patient with AG who presented with dizziness, and whose MRI images revealed a circumscribed lesion with heterogeneous contrast enhancement and evidence of previous bleeding. Thirty-three patients with AG have been reported to date.(More)
Silibinin mostly has been used as hepatoprotectants, but it has other interesting activities, e.g. anti-cancer, cardial protective and brain-protective activities. A previous study demonstrated that silibinin protected amyloid β (Aβ)-induced mouse cognitive disorder by behavioural pharmacological observation. This study assessed the effect of silibinin on(More)
Endovascular treatment of ruptured tiny intracranial aneurysms (RTIA) is technically challenging. We retrospectively collected and analyzed the clinical data of 51 patients with RTIA who underwent attempted endovascular treatment at our institution between November 2000 and April 2009. Forty-nine patients were successfully treated by coiling alone (29(More)
In this study, the effects of cadmium containing QDs (such as CdSe/ZnS and CdSe QDs) and bulk CdCl2 in pregnant mice, their fetuses, and the pregnancy outcomes were investigated. It was shown that although the QDs and bulk CdCl2 were effectively blocked by the placental barrier, the damage on the placenta caused by CdSe QDs still led to fetus malformation,(More)
The aim of this study is to evaluate the performance of a motion capture system and discuss the application potential of the proposed system in in vivo bone-segment deformation measurements. In this study, the effects of the calibration procedure, camera distance and marker size on the accuracy and precision of the motion capture system have been(More)
This paper deals with distributed detection using a tandem network with conditionally dependent observations. Our approach utilizes a recently proposed hierarchical conditional independence model where a hidden variable is introduced and induces conditional independence among sensor observations. If the hidden variable is discrete, optimal local decision(More)
OBJECTIVE To investigate the effect of ultrasound in the treatment of osteoarthritis of the knee. METHODS   Eighty-seven out- and in-patients with osteoarthritis of the knee (15 men and 72 women) underwent ultrasonic therapy from February to October 2010. The patients were randomly assigned to an ultrasound group (Group A) and a placebo group (Group B).(More)
