Intestinal topical lidocaine spray improves the efficacy and safety of endoscopic sigmoid polypectomy.

Background And Aims: Endoscopic polypectomy can prevent colorectal cancer. Adequate surgical field visualization is crucial to complete resection. To prevent visual field loss caused by intestinal peristalsis, we investigated the efficacy and safety of topical lidocaine spraying during the endoscopic sigmoid polypectomy (ESP).

[Placenta-derived mesenchymal stem cells with HLA-G positive expression induce Treg ].

Objective: To study placenta-derived mesenchymal stem cells with HLA-G (Human Leukocyte Antigen, HLA-G) positive expression induce Treg (regulatory T cell, Treg) in vitro.

Methods: placenta-derived mesenchymal stem cells were separated from neonatal placenta; PEGFP - N1 -HLA-G plasmid was transfected in placenta-derived mesenchymal stem cells by liposome transfection.The cells were divided into 3 groups including control group, PEGFP-N1 group and PEGFP-N1-HLA-G group, 5 complex walls in each group.

tert-Butyl 4-({[(E)-1,3-dimethyl-5-phen-oxy-pyrazol-4-yl]meth-yl}amino-oxymeth-yl)benzoate.

The title compound, C(24)H(27)N(3)O(4), also known as fenpyroximate, is a commercial acaricide. The benzene ring of the phen-oxy group is approximately perpendicular to the pyrazole ring with a dihedral angle of 84.37 (11)°.
