Kinesins are encoded by a large gene family involved in many basic processes of plant development. However, the number of functionally identified kinesins in rice is very limited. Here, we report the functional characterization of Brittle Culm12 (BC12), a gene encoding a kinesin-4 protein. bc12 mutants display dwarfism resulting from a significant reduction(More)
Protein kinases play an important role in regulating the response to abiotic stress in plant. CIPKs are plant-specific signal transducers, and some members have been identified. However, the precise functions of novel CIPKs still remain unknown. Here we report that HbCIPK2 is a positive regulator of salt and osmotic stress tolerance. HbCIPK2 was screened(More)
Congenital quadricuspid aortic valve is a rare cardiac anomaly. More than half of the patients with this abnormality will develop aortic insufficiency in adulthood. It is vital that patients with quadricuspid aortic valve who present with progressive aortic regurgitation undergo valve replacement or repair at appropriate time. Here, we present two cases of(More)
Transforming growth factor β (TGF-β), a cytokine, and its receptors play a vital role during normal embryogenesis, cell proliferation, differentiation, apoptosis and migration. Ran-binding protein in the microtubule-organizing center (RanBPM) serves as a scaffold protein that has been shown to interact with many other proteins, such as MET, Axl/Sky, TRAF6,(More)
RASSF1A is a novel putative tumor suppressor gene located in 3p21.3 region. The most common inactivation mechanism of RASSF1A is promoter hypermethylation, which is observed in multiple solid tumors including lung cancer. In the present study, we identified the methylation status of RASSF1A in lung cancer sera using methylation-specific PCR and analyzed its(More)
BACKGROUND Temporarily pulmonary hilum clamping is available for the trauma surgeon to deal with serious pulmonary injuries, but the physiologic influence needs further evaluation. This study was to establish a temporary pulmonary hilum clamping model for thoracic damage-control surgery and determine the safety time latitude of this manipulation. METHODS(More)
A chromium-reducing strain QH-1, identified as Bacillus sp., was isolated from soil under chromium-containing slag heap in Qinghai high altitude area, China. The strain was found to resist 200 mg/L Cr(VI), and Cr(VI) negatively affects the metabolic activity of the cells, as well as the cell morphology of Bacillus sp. QH-1. The reduction efficiency of(More)
Spectrum efficient data transmission is of key interest for high capacity optical communication systems considering the limited available bandwidth. Transmission of the high speed signal with higher-order modulation formats within the Nyquist bandwidth using coherent detection brings attractive performance advantages. However, high speed Nyquist signal(More)
We propose and experimentally demonstrate a simplified coherent receiver based on heterodyne detection with only two balanced photodetectors and two analog-to-digital converters. The polarization diversity hybrid can be simplified relative to the conventional one. The detected intermediate frequency signals are first downconverted to baseband with inphase(More)
We propose and demonstrate a novel WDM-CAP-PON based on optical single-side band (OSSB) multi-level multi-band carrier-less amplitude and phase modulation (MM-CAP). To enable high-speed transmission with simplified optical network unit (ONU)-side digital signal processing, 4-level 5 sub-bands CAP-16 is used here, which is generated by the digital to(More)
