OBJECTIVES Tadalafil, an oral phosphodiesterase type-5 inhibitor, induces pulmonary vasorelaxation by inhibiting the breakdown of cyclic guanosine monophosphate whereas simvastatin, an oral 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase inhibitor, has been shown to reverse pulmonary hypertension (PH) and attenuate vascular remodeling in animal models of(More)
Nobiletin, a bioactive polymethoxylated flavone isolated from citrus fruits, has been proven to prevent cancer and inflammation. Dietary flavonoids have been shown to reduce the risk of cardiovascular diseases (CVDs), and platelet activation plays a crucial role in CVDs. This study investigated the effect of nobiletin on platelet activation in vitro and in(More)
In this paper, we propose a new alternative blind SR to estimate motion, blurring, and higher resolution (HR) image alternatively and iteratively in case the three are all unknown. The related ternary optimization is first divided into two alternate and iterative optimizations, in which the unitary one is about motion estimation and the dualistic one is(More)
OBJECTIVE To explore the effect of low molecular weight heparin (LMWH) on the changes of pulmonary surfactant associated protein A (SPA) of rats in acute pulmonary embolism. METHODS Male SD rats were injected with medical gelfoam microspheres via jugular vein to induce PE model. Rats were randomized into three groups: control group (n = 8), embolism for 2(More)
OBJECTIVE To study the changes of pulmonary surfactant associated protein A (SPA) of lung tissue in acute pulmonary embolism (PE). METHODS Male SD rats were injected with medical gelfoam microspheres via jugular vein to induce the PE model. Thirty-two rats were randomized into four groups: a control group (n = 8) and three groups of embolism for 24 h (n =(More)
Heme oxygease-1 (HO-1) is the rate-limiting enzyme in heme catabolism. Induction of HO-1 has been shown to have vasodilatory, anti-inflammatory, and proapoptotic effects. More recently, experimental studies suggested the potential of simvastatin as a novel therapy for pulmonary hypertension (PH); however, the underlying mechanism remains to be investigated.(More)
BACKGROUND Psychological distress has been widely studied in many cardiovascular and pulmonary diseases, but the condition in acute pulmonary embolism (APE) is unknown. The purpose of this study was to investigate levels of depression and anxiety and their influencing factors in APE patients. METHODS Sixty consecutive patients with APE were subjected to(More)
Document image binarization is the basis of Optical Character Recognition (OCR). For B.Gatos' adaptive binarization method exists the shortcomings, we propose an improved adaptive document image binarization method which consists of four steps. The first step is dedicated to a denoising procedure using a low-pass Wiener filter based on local statistics. In(More)
Crosslinked starch phosphates (CSP) with different contents of phosphate groups were used to adsorb Zn(II) from aqueous solution. Effects of adsorption time, initial concentration of Zn(II) ion, and temperature on the adsorption of Zn(II) by CSP were studied, and the equilibrium, thermodynamics and kinetics of the adsorption process were further(More)
Manchurian ash (Fraxinus mandshurica Rupr.) is a valuable hardwood species in Northeast China. In cultures of F. mandshurica, somatic embryos were produced mainly on browned explants. Therefore, we studied the mechanism of explant browning and its relationship with somatic embryogenesis (SE). We used explants derived from F. mandshurica immature zygotic(More)
