OBJECTIVE/HYPOTHESIS Loss of auditory function after cochlear implant (CI) electrode insertion occurs in two stages in the laboratory rat. An immediate loss is followed by a progressive loss over 7 days. Similar stages of acute and progressive neuronal loss occur after trauma in the central nervous system where hypothermia has been shown to have a(More)
The frequent occurrence of natural disasters and accidents urge a strong demand on a novel localization system for search and rescue. This paper presents a scheme of wireless phone-based detection and localization system. The system can induce the mobile phones to transmit radio frequency signals to outside receiver without victims' activation. Moreover,(More)

Objective Establishing a fingerprint method to identify the characteristic chemicals in the roots of Gentiana macrophylla and evaluate their quality. Methods RP-HPLC was developed for fingerprint analysis and determination of four ingredients in G. macrophylla roots from different sources. LC-ESI-TOF-MS was employed to identify the chromatographic peaks of(More)
To investigate the effect of dexamethasone on the expression levels of P-selectin protein in multiple organs of rats with severe acute pancreatitis (SAP). Rats were randomly divided into sham-operated, model control, and dexamethasone-treated groups. At 3, 6, and 12 h after operation, the expression levels of P-selectin protein in one-third of the rats in(More)
The blend of poly(lactic acid) (PLA) and poly(butylene succinate) (PBS) were prepared and extruded with various compositions and their molded properties were examined. Thermogravimetric analysis showed that thermal stability of the blends was higher than that of pure PLA and the weight loss of PLA/PBS (40/60 wt%) was lower than neat polymers. Differential(More)
OBJECTIVE To investigate angiographical characteristics of carotid, vertebral, subclavian, and renal arteries in the type 2 diabetic patients with lower extremities peripheral arterial disease (LEPAD). METHODS There were 104 type 2 diabetic patients with LEPAD recruited in this study, who received digital subtract arteriography (DSA). Ankle-brachial index(More)
This paper describes the pitch detection techniques and voiced/unvoiced decision using normalized cross correlation function (NCCF) method and circular average magnitude difference function (CAMDF) method involving the preprocessing and the post processing. Major innovations include: The pitch period candidates selection based on NCCF and CAMDF, the simple(More)
Until now, no study has focused exclusively on low-flow retrobulbar intraconal venous malformations (RIVMs) which may require treatment due to cosmetic defect, pain, and visual dysfunction. The treatment for RIVMs which surround the optic nerve remains challenging. This case series aimed to evaluate the technical feasibility, effectiveness, and safety of(More)
OBJECTIVE To evaluate the Digital Subtract Arteriography (DSA) characteristics of lower limb arterial diseases in patients with diabetic feet and to explore the correlation between DSA and Ankle-brachial index (ABI). METHODS Fifty-two patients with diabetic feet were recruited in this study. ABI and DSA of bilateral lower extremities were examined to(More)
Before 131I-HAb18F(ab')2 administration, 24 cases of mid-term or advanced hepatocellular carcinoma(HCC) were given Lugol's Liquid to block the thyroid gland, and submitted to hepatic colloid imaging. The cases were randomly divided into 3 groups. Then 131I-HAb18F(ab')2 was injected into the target hepatic artery with doses of 0.5, 0.75, 1.0 mCi/kg,(More)
