Numerous studies indicate that target gene silencing by RNA interference (RNAi) could lead to insect death. This phenomenon has been considered as a potential strategy for insect pest control, and it is termed RNAi-mediated crop protection. However, there are many limitations using RNAi-based technology for pest control, with the effectiveness target gene(More)
The brown planthopper (BPH, Nilaparvata lugens) is a destructive, monophagous, piercing-sucking insect pest of rice. Previous studies indicated that jasmonic acid (JA) positively regulates rice defense against chewing insect pests but negatively regulates it against the piercing-sucking insect of BPH. We here demonstrated that overexpression of allene oxide(More)
BACKGROUND The number of Clara cells and the Clara cell 16-kDa protein (CC16) levels of the lung decrease in patients with chronic obstructive pulmonary disease (COPD). N-acetylcysteine (NAC) is a powerful antioxidant and can reduce the frequency of acute exacerbations of COPD. But the exact mechanism is unclear. The present study was designed to(More)
BACKGROUND The hygiene hypothesis has been proposed to explain the pathogenesis of asthma. Allergen exposure was shown to inhibit asthma in an animal model. But the optimal timing of allergen exposure remains unclear. This study aims to explore the time effcct of allergen exposure and the possible mechanisms. METHODS Neonate Wistar rats were randomly(More)
Based on fully understanding the impacts on industry safety made by transnational corporations, this essay will try to design new evaluation system with absorbing the essence of former industry evaluation system which will analyze in four parts: industry environment, industry competitiveness, industry dependence, industry control.
Under the influence of economic globalization, transnational investment has improved the development of China's economy. At the same time, it arouses numbers of problems, conflicts and crises. Local industry is suffering an attack which even appears industry safety problems. On the basis of references, it can be concluded that only by deeply understanding(More)
BACKGROUND AND AIMS Invasive pulmonary aspergillosis (IPA) has been reported as a severe opportunistic infection in immunocompromised patients without neutropenia or cancer. Patients with antineutrophil cytoplasmic antibody associated vasculitis (AAV) with immunosuppressive treatment are susceptible to IPA, but only few cases were reported in the(More)
OBJECTIVE To compare the values of dual-source computed tomographic angiography (DSCTA) and digital subtraction angiography (DSA) in evaluating intracranial aneurysms in patients with nontraumatic subarachnoid hemorrhages (SAH) . METHODS Totally 80 nontraumatic SAH patients were evaluated with both DSCTA and DSA. With the results of DSA as the gold(More)
