Enhanced anti-inflammatory activity of chlorogenic acid via folic acid-TPGS-modified liposomes encapsulation: characterization and evaluation on colitis mice.

Introduction: Chlorogenic acid (CGA) has been identified to possess salient anti-inflammatory, antioxidant, and anticancer attributes. However, its application is limited by its instability and low bioavailability. Liposomes have been considered effective pharmaceutical delivery vehicles due to their ability to continuously release loaded drugs, improve drug stability, and display good biocompatibility.

Biomass-assisted fabrication of rGO-AuNPs as surface-enhanced Raman scattering substrates for in-situ monitoring methylene blue degradation.

Reduced graphene oxide-gold nanoparticles nanocomposites (rGO-AuNPs) with high surface-enhanced Raman scattering (SERS) activity was created by biomass-assisted green synthesis with Lilium casa blanca petals biomass for the first time, and its application for methylene blue (MB) degradation was explored through in-situ monitoring. Lilium casa blanca petals biomass was used as a reducing agent to reduce GO and chloroauric acid successively when carrying out rGO-AuNPs in-situ synthesis while it also acted as a capping agent. The produced rGO had oxygen-containing functional groups which had an outstanding performance in enhancing the SERS effect.

The Effect of Single-Dose Ougan Juice Application on the Pharmacokinetics of Erlotinib.

The aim of our study was to investigate the effects of single-dose Ougan (Citrus reticulata cv. Suavissima) juice application on the pharmacokinetics of erlotinib in vivo. Twelve Sprague-Dawley rats were randomly divided into the Ougan juice and control groups ( = 6 each).

In vitro metabolism of phenytoin in 36 CYP2C9 variants found in the Chinese population.

Cytochrome P450 2C9 (CYP2C9) is an important member of the cytochrome P450 enzyme superfamily, with 57 CYP2C9 allelic variants being previously reported. Recently, we identified 22 novel alleles (*36 -*56 and N418T) in the Han Chinese population. This study aims to assess the catalytic activities of wild-type (CYP2C9*1) and 36 CYP2C9 allelic variants found in the Chinese population toward phenytoin (PHT) in vitro.

[Expression of lymphotactin in renal tuberculosis].

Aim: To study the expression of lymphotactin in normal kidney and renal tuberculosis and the arrangement of lymphotactin and infiltrating CD4(+) T cells and CD8(+) T cells in renal tuberculosis.

Methods: HLptn cDNA of tissues from six cases with normal kidneys and ten cases with tuberculous kidneys was amplified by RT-PCR. The RT-PCR products were separated with 2% of gel.

Identification of functional candidate genes for drought tolerance in rice.

Drought tolerance (DT) in rice is known to be controlled by many quantitative trait loci (QTLs) and involved differential expression of large numbers of genes, but linking QTLs with their underlying genes remains the most challenging issue in plant molecular biology. To shed some light on this issue, differential gene expression in response to PEG simulated drought in 3 unique genetic materials (a lowland rice, IR64 and its derived line, PD86 which has 11 introgressed DT QTLs, and a upland rice IRAT109) was investigated using a PCR-based subtractive hybridization strategy. More than 300 unique subtracted cDNA sequences, covering genes of diverse cellular activities and functions, were identified and confirmed by semi-quantitative and quantitative RT-PCR.

[Preliminary study on lymphotactin expression of monocyte-derived dendritic cells].

Aim: To induce dendritic cells (DCs) from human peripheral blood monocytes in vitro and to investigate the kinetics lymphotactin (Lptn) mRNA expression.

Methods: Monocytes were isolated from normal human peripheral blood cells by density gradient centrifugation and the plastic-adherent cells were cultured with the cytokines (rhGM-CSF, rhIL-4, rhTNF-alpha). The immature and mature DCs' surface antigens CD1a and CD83 were analyzed by flow cytometry (FCM).

[Isolation and analysis of isolation of differentially-methylated fragment CIDM7 in rice induced by cold stress].

By using restriction enzyme isoschizomers that differ in their sensitivity to methylation of their recognition sites, AFLP analysis is carried out to analyse differences of the methylation state of anonymous CCGG sequences between cold-treated(5 degrees for 2 d) and control 9311(Oryza sativa L.) leaves DNA. Demethylation or De novo methylation induced by cold stress are found in some CCGG sites.
