Synthesis and Flame Retardant Behavior of Phosphorous- and Nitrogen-Containing Copolymer and Its Application in Polypropylene.

In this study, a 4-(hydroxymethyl)-2,6,7-trioxa-1-phosphabicyclo[2.2.2]octane 1-oxide (PEPA)-functionalized acrylate monomer, PEPAA, is designed and utilized for the synthesis of macromolecular flame retardants poly(PEPAA-co-AM) with varying PEPAA/AM ratio through copolymerization with acrylamide (AM).

The genome of Aechmea fasciata provides insights into the evolution of tank epiphytic habits and ethylene-induced flowering.

Aechmea fasciata is one of the most popular bromeliads and bears a water-impounding tank with a vase-like rosette. The tank habit is a key innovation that has promoted diversity among bromeliads. To reveal the genomic basis of tank habit formation and ethylene-induced flowering, we sequenced the genome of A.

The Musa troglodytarum L. genome provides insights into the mechanism of non-climacteric behaviour and enrichment of carotenoids.

Background: Karat (Musa troglodytarum L.) is an autotriploid Fe'i banana of the Australimusa section. Karat was domesticated independently in the Pacific region, and karat fruit are characterized by a pink sap, a deep yellow-orange flesh colour, and an abundance of β-carotene.

Yttrium(iii) coordination polymer micro/nanospheres with single ligand and dual ligands.

In this work, yttrium(iii) coordination polymer (Y-CP) ball-flower-shaped microparticles with diameters ranging from 5 μm to 10 μm were synthesized using vanillin and asparagine as ligands under solvothermal conditions at 150 °C for 24 h. Then, we investigated the reaction influencing factors such as the concentration of reactants (involving vanillin, asparagine, and rare earth), reaction temperature, and reaction time. Both uniform and sphere-like nanoparticles with an average size of ∼50 nm were obtained using vanillin as a ligand at 120 °C for 12 h.

PEGylated mesoporous BiS nanostars loaded with chlorin e6 and doxorubicin for fluorescence/CT imaging-guided multimodal therapy of cancer.

Taking advantage of the mesoporous structure of bismuth sulfide nanostars (BiS NSs), a chemotherapeutic drug of doxorubicin (DOX) and a photosensitizer of chlorin e6 (Ce6) were concurrently loaded in the PEGylated BiS NSs to formulate a multifunctional nanocomplex (BPDC NSs) for tumor theranostics. BPDC NSs have excellent photothermal conversion efficiency and a capacity of yielding reactive oxygen species (ROS) upon laser irradiation, and can realize on-demand drug release by either pH-activation or thermal induction. Accumulation of the nanodrug could be monitored in real-time by infrared thermal imaging, fluorescence imaging and computed tomography (CT).

Speed tracking and synchronization of multiple motors using ring coupling control and adaptive sliding mode control.

A new control approach for speed tracking and synchronization of multiple motors is developed, by incorporating an adaptive sliding mode control (ASMC) technique into a ring coupling synchronization control structure. This control approach can stabilize speed tracking of each motor and synchronize its motion with other motors' motion so that speed tracking errors and synchronization errors converge to zero. Moreover, an adaptive law is exploited to estimate the unknown bound of uncertainty, which is obtained in the sense of Lyapunov stability theorem to minimize the control effort and attenuate chattering.

CD105 promotes hepatocarcinoma cell invasion and metastasis through VEGF.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related morbidity and mortality. Tumor neovascularization is necessarily required for tumor progression and metastasis. CD105 and vascular endothelial growth factor (VEGF) have separately been identified as important contributors to angiogenesis; however, it is unclear if these factors interact to promote the progression of HCC.

[Effect of comprehensive control project on schistosomiasis in Nanjian county].

The comprehensive control project for schistosomiasis was implemented in Nanjian County from 2004 to 2008. After the implementation of the control project, the infection rates of population and livestock decreased by 94.39% and 83.
