Citrus canker, an epidemic quarantine disease caused by Xanthomonas axonopodis pv. citri, has brought a great damage in citrus production worldwide. Herein, a rice PRR （pattern recognition receptor） gene Xa21 together with GUS reporter gene and hygromycin phosphotransferase gene （HPT） was introduced into Anliucheng sweet orange （Citrus sinensis Osbeck） via Agrobacterium-mediated transformation of embryogenic callus. The transgenic calluses were screened on MT basal medium containing hygromycin （HYG） and detected by histochemical GUS staining. The transgenic plantlets were recovered through somatic embryogenesis pathway. The regenerated plantlets were accustomed to and maintained in the greenhouse. The transgene integration of recovered plantlets was identiifed by PCR and Southern blot hybridization. It showed that all the transgenic plantlets tested had undergone single copy integration, the expression of Xa21 in eight different transgenic lines detected by qRT-PCR can be divided into three grades, high for T5 and T6, middle for T4 and low for the rest. The tolerance to citrus canker disease of the three recovered transgenic lines T2, T4 and T6 was assessed by in vitro pin-puncture inoculation. The results showed that all the three transgenic lines conferred improved resistance to citrus canker bacterium infection and the T4 transgenic line displayed the highest resistance. The mechanism and feasibility of rice Xa21 in triggering innate immunity in citrus was brielfy discussed.

In this paper, using finite-time control method, we consider the disturbance analysis of a second-order system with unknown but bounded disturbance. We show that the states of the second-order system will be stabilized to a region containing the origin. The radius of this region is determined by the control parameters and can be rendered as small as desired. The rigorous stability analysis is also given. Compared with the conventional PD control law, the finite-time control law yields a better disturbance rejection performance. Numerical simulation results show the effectiveness of the method.

The human body, such as hair, serves as a prism through which historical and cultural contexts are effectively refracted. Despite its historical and cultural significance, the role of hair, however, remains curiously a marginalized subject among the renewed interests on the body in the academic fields. In this paper, the author attempts to politicize the queue from 3 perspectives： maintaining a certain prescribed hairstyle is a top-down gesture to construct national conformity; the boundary between Manchu and Han is invoked and reinvented through the battles surrounding the queue politic in late Qing and early Republic; the widespread debate between keeping the queue and cutting the queue at the turn of the 20th century epitomizes the haunting rhetoric of traditionalism and modernism pursuit of modernity in China.

Background Osteoclast-associated receptor （OSCAR） is a member of the newly identified leukocyte receptor complex,and has recently been described as a key molecule in osteoclastogenesis. In this study, we measured the levels of soluble osteoclast-associated receptor （sOSCAR） in the serum of rheumatoid arthritis （RA） patients and healthy controls to examine whether sOSCAR may play a role in the process of inflammatory *** Enzyme-linked immunosorbent assay （EliSA） was used to measure the levels of sOSCAR in the serum of 40 healthy controls and 40 RA *** The serum levels of sOSCAR were significantly lower in RA patients than in healthy controls, and were inversely associated with inflammatory *** sOSCAR is decreased in patients with RA and reduced levels of the protein are associated with increased inflammatory response.
