Role of TREM-1 in the development of early brain injury after subarachnoid hemorrhage.

Triggering receptor expressed on myeloid cells-1 (TREM-1) was found to be induced in the context of subarachnoid hemorrhage (SAH) before. This study further investigates its role in the development of SAH-induced early brain injury (EBI). Firstly, rats were randomly divided into Sham and SAH groups for analysis of temporal patterns and cellular localization of TREM-1.

[Effect of polysaccharides from Polygonatum sibiricum on lipid-metabolism related mRNA and protein expression in hyperlipidemic mice].

To study the effect of polysaccharides from Polygonatum sibiricum on mRNA and protein expressions of blood lipid metabolism in hyperlipidemic mice. The mice were randomly divided into 6 groups, namely the blank control group, the hyperlipidemia model group, the simvastatin group, and low, middle and high-dose PSP groups (200, 400, 800 mg·kg⁻¹·d⁻¹). Each group of the mice was administrated intragastrically for 14 days, respectively.

[Novel liposomal drug delivery system actively targeting Cryptococcus neoformans and elimination of infection].

The purpose of this study is to develop a liposomal drug delivery system actively targeting Cryptococcus neoformans and explore its feasibility in therapy of cryptococcal infection. The specific fungi-binding peptide was screened from 12-mer random phage display library, and linked to PEG-DSPE as the functional material of liposomes. The targeting capability of peptide-modified liposomes were investigated by fungi binding assay in vitro and fluorescence imaging in vivo.

[Construction of biotin-modified polymeric micelles for pancreatic cancer targeted photodynamic therapy].

In this study, we explored the feasibility of biotin-mediated modified polymeric micelles for pancreatic cancer targeted photodynamic therapy. Poly (ethylene glycol)-distearoyl phosphatidyl ethanolamine (mPEG2000-DSPE) served as the drug-loaded material, biotin-poly(ethylene glycol)-distearoyl phosphatidyl ethanolamine (Biotin-PEG3400-DSPE) as the functional material and the polymeric micelles were prepared by a thin-film hydration method. The targeting capability of micelles was investigated by cell uptake assay in vitro and fluorescence imaging in vivo and the amounts of Biotin-PEG-DSPE were optimized accordingly.

Long-circulating liposomal daptomycin enhances protection against systemic methicillin-resistant Staphylococcus aureus infection with improved therapeutic potential.

In the face of escalating problems with pathogen control, the development of proper formulations of existing antibiotics is as important as the development of novel antibiotics. Daptomycin is a lipopeptide antibiotic with potent activity against Gram-positive bacteria. Currently, only injectable solution of daptomycin has been approved for clinical use.

[Silica-coated ethosome as a novel oral delivery system for enhanced oral bioavailability of curcumin].

The aim of this study is to investigate the feasibility of silica-coated ethosome as a novel oral delivery system for the poorly water-soluble curcumin (as a model drug). The silica-coated ethosomes loading curcumin (CU-SE) were prepared by alcohol injection method with homogenization, followed by the precipitation of silica by sol-gel process. The physical and chemical features of CU-SEs, and curcumin release were determined in vitro.

N-Benzyl-2-(2-chloro-4-methyl-phen-oxy)acetamide.

The structure determination of the title compound, C(16)H(16)ClNO(2), was performed as part of a project on the inter-actions between small organic mol-ecules and proteins. In the crystal structure, the dihedral angle between the two aromatic rings is 16.14 (12)°.

[Induction of petal-like structures from petals of Crocus sativus L. and the differentiation of style-stigma-like structures in vitro].

Firstly the petal of Crocus sativus L was cultured on the medium that supplemented with different combinations of hormones. The petal-like structures(PLS) were induced on medium, but the induction rates were different in various medium. The highest induction rate of petal-like structures was obtained on the media that was supplemented with NAA (4 mg/L) and KT (8 mg/L).
