Harmonic Suppression Induced by Three-Electron Dynamics of Li in Strong Laser Fields.

We build a model to elucidate the high harmonic generation in combined EUV and midinfrared laser fields by embodying the spin-resolved three-electron dynamics. The EUV pulse ionizes an inner-shell electron, and the midinfrared laser drives the photoelectron and steers the electron-ion rescattering. Depending on the spin of the photoelectron, the residual ion including two bound electrons can be either in a single spin configuration or in a coherent superposition of different spin configurations.

Development of bacterial cellulose/chitin multi-nanofibers based smart films containing natural active microspheres and nanoparticles formed in situ.

Nanofiber-based materials have recently gained increasing attention in food packaging, drug delivery, and biomedical applications. In this study, a multi-nanofibers composite film was developed based on bacterial cellulose nanofiber (BCNF)/chitin nanofiber (CNF) hybridization. The nanofibers were responsible for the formation of well-dispersed curcumin (Cur) micro/nanoparticles in the nanocomposite films.

Outcomes of the national programme on prevention of mother-to-child transmission of hepatitis B virus in China, 2016-2017.

Background: In addition to providing free hepatitis B vaccine (HBvacc) series to all infants in China since 2005, the national programme on prevention of mother-to-child transmission (PMTCT) of hepatitis B virus (HBV) started providing free hepatitis B immunoglobulin for all new-borns born to hepatitis B surface-antigen (HBsAg) positive mothers in 2010. However, few studies have evaluated the effectiveness of the PMTCT programme. Therefore, we aimed to investigate the outcomes of the programme and identify associated factors.

Drug release and antioxidant/antibacterial activities of silymarin-zein nanoparticle/bacterial cellulose nanofiber composite films.

Bacterial cellulose (BC) is a biopolymer composed of nanofibers which has excellent film-forming ability. However, BC do not have antibacterial or antioxidant activity, thus limiting the applicability of BC for food and biomedical applications. In this study, flavonoid silymarin (SMN) and zein were assembled into spherical SMN-Zein nanoparticles that could be effectively adsorbed onto BC nanofibers.

[An analysis of antiretroviral therapy outcomes in the Medecins Sans Frontieres/Guangxi Center for Disease Control and Prevention HIV/AIDS project].

Objective: To evaluate the 3-year outcomes of the Medecins Sans Frontieres/Guangxi Center for Disease Control and Prevention comprehensive and free of charge HIV/AIDS treatment and care project.

Methods: We present a detailed retrospective analysis of treatment outcomes of 432 cases who received highly active antiretroviral therapy (HAART) from December 2003 to December 2006.

Results: Among the adult patients who received HAART, the mortality rate was 6.
