Nine selected antibiotics in the Victoria Harbour of Hong Kong and the Pearl River at Guangzhou, South China, were analyzed using high-performance liquid chromatography-electrospray ionization tandem mass spectrometry. The results showed that the concentrations of antibiotics were mainly below the limit of quantification (LOQ) in the marine water of(More)
OBJECTIVE Primary aldosteronism is the most frequent cause of secondary hypertension and is associated with more prominent left ventricular hypertrophy and increased myocardial fibrosis. However, the reversibility of cardiac fibrosis is still unclear. Our objective was to investigate myocardial fibrosis in primary aldosteronism patients and its change after(More)
Titanium (Ti) based spinal fusion cages are frequently used in the clinics for the treatment of spinal degeneration and related diseases, however, their further clinical application is generally harassed by several drawbacks such as stress shielding, non-biodegradability and additional bone grafting procedure. Our earlier work has demonstrated the efficacy(More)
A low-power ultra-compact CMOS low-noise amplifier (LNA) in a shunt-resonating current-reused topology is presented. The common-source transistors are connected with a shunt-resonating inter-stage match network such that the bias current is shared to have low power consumption and RF signal is doubly amplified to have high gain and low noise figure. The(More)
BACKGROUND AND AIM Antemortem diagnosis of hepatocellular carcinoma (HCC) with cardiac metastasis is uncommon. To clarify the clinical manifestation and survival of HCC patients with cardiac metastases, we initiated the present study. METHODS We retrospectively analyzed 48 HCC patients with metastases into cardiac cavity diagnosed antemortem. The baseline(More)
The occurrence and seasonal changes of antibiotics in the Victoria Harbour and the Pearl River were studied using high-performance liquid chromatography-electrospray ionization tandem mass spectrometry with multiple reaction monitoring (MRM). The results showed that the concentrations of antibiotics were mainly below the limit of quantification (LOQ) in the(More)
Water damage and moisture in buildings may become more prevalent due to the increasing frequency of extreme precipitation and flooding events resulting from climate change. However, the effects of moisture levels on phthalate emissions from building materials are still underreported. This study aims to evaluate the effect of moisture content (MC) on the(More)
OBJECTIVE To determine whether the etiology of renal artery stenosis changed. To investigate the clinical characteristics and current therapeutic situation of atherosclerotic renal artery stenosis (ARAS). METHODS Retrospective analysis was performed in 144 cases of renal artery stenosis diagnosed by angiography (> or = 50% luminal narrowing) from 1979 to(More)
