Structure and physicochemical properties of rice starch modified with dodecenyl succinic anhydride and its use for microencapsulating Pediococcus acidilactici probiotic.

Polysaccharides are used as wall materials to extend the shelf life of lactic acid bacteria. Ice crystal formation during freezing leads to probiotic death. We prepared a series of dodecenyl succinic anhydride (DDSA)-modified rice starches with varying degrees of substitution and compared their functional properties.

A hierarchical approach for rigid-body dynamics model simplification of a high-speed parallel robot by considering kinematics performance.

Considering the real-time control of a high-speed parallel robot, a concise and precise dynamics model is essential for the design of the dynamics controller. However, the complete rigid-body dynamics model of parallel robots is too complex for online calculation. Therefore, a hierarchical approach for dynamics model simplification, which considers the kinematics performance, is proposed in this paper.

A high-precision digital integrator based on the Romberg algorithm.

An integrator is widely used for measurement in the field of power systems, and it is a key technology in signal processing. According to research on the digital integrator based on the traditional Newton-Cotes algorithm, the high-frequency response of the low-order Cotes formula is usually poor and the design of the transfer function introduced by the high-order Cotes formula is too complex. In this paper, we analyze the error between the composite Newton-Cotes algorithm and the ideal transfer function.

Dynamic changes in biomarkers in acute human immunodeficiency virus infections: a case report.

Background: The highest incidence of human immunodeficiency virus infection in China is among men who have sex with men. This case report aims to describe the dynamic changes in biomarkers in an acute human immunodeficiency virus infection of a Han Chinese man who has sex with men, and to illustrate the possibility of using these biomarkers for the early detection of human immunodeficiency virus infection in Chinese hospital settings.

Case Presentation: The 25-year-old Han Chinese male patient presented himself with an 8-day history of symptoms and signs of upper respiratory viral infections to a sexually transmitted infection clinic of a hospital setting in Shanghai.

Twenty-five-year changing pattern of gonococcal antimicrobial susceptibility in Shanghai: surveillance and its impact on treatment guidelines.

Background: Antimicrobial resistance of Neisseria gonorrhoeae is a serious health problem in China. Gonococcal antimicrobial susceptibility has been monitored in Shanghai since 1988. In this study, we examined the changing pattern of gonococcal antimicrobial susceptibility based on data from N.

Comparing the performance of traditional non-treponemal tests on syphilis and non-syphilis serum samples.

The goal of the present study was to determine the performance of two traditional non-treponemal tests for syphilis. Syphilis sera (n = 209) included different stages of disease, and control sera (n = 247) were from patients with tumours, leprosy, systemic lupus erythematosus, hepatitis, pregnant women and healthy individuals. Treponema pallidum ELISA, Treponema pallidum particle agglutination and rapid treponema-specific tests were used as gold standards.

Evaluation of a new chemiluminescence immunoassay for diagnosis of syphilis.

Objective: To assess the sensitivity, specificity, and feasibility of a new chemiluminescence immunoassay (CLIA) in the diagnosis of syphilis.

Methods: At first, a retrospective study was conducted, using 135 documented cases of syphilis and 30 potentially interfering samples and 80 normal sera. A prospective study was also performed by testing 2, 071 unselected samples for routine screening for syphilis.
