一般說明

右旋糖酐是分子量为≥1,000道尔顿的多糖，具有由α-连接的D-葡吡喃糖基重复单元组成线性骨架。右旋糖酐是某些细菌产生的一种胞外多糖。由肠膜明串珠菌 (Leuconostoc mesenteroides) 和短乳杆菌 (Lactobacillus brevis) 通过蔗糖合成。细菌合成右旋糖酐用于生物被膜形成，致病菌则将其作为保护性包被以便入侵宿主的吞噬细胞。肠膜明串珠菌
右旋糖酐（Mw：5000）可作为分析标准品，用于校准凝胶渗透色谱 (GPC) 的色谱柱。

應用

将右旋糖酐用作长的亲水性间隔臂提高了作用于大分子的固定化蛋白质的性能。

Dextran-functionalized magnetic fluid mediating magnetohyperthermia combined with preventive antioxidant pequi-oil supplementation: potential use against cancer.

Ana Luisa Miranda-Vilela et al.

Journal of biomedical nanotechnology, 9(7), 1261-1271 (2013-08-06)

This work aimed to test a dextran-functionalized magnetic fluid (DexMF) sample in mediating magnetohyperthermia to treat an advanced clinical Ehrlich-solid-tumor, to verify the effects of oral antioxidant administration of pequi-oil on this treatment and to investigate the potential of these

Materials characterization of the low temperature sensitive liposome (LTSL): effects of the lipid composition (lysolipid and DSPE-PEG2000) on the thermal transition and release of doxorubicin.

David Needham et al.

Faraday discussions, 161, 515-534 (2013-06-29)

This paper describes how we have used material science, physical chemistry, and some luck, to design a new thermal-sensitive liposome (the low temperature sensitive liposome (LTSL)) that responds at clinically attainable hyperthermic temperatures releasing its drug in a matter of

Enhanced delivery system of flutamide loaded chitosan-dextran sulphate nanoparticles for prostate cancer.

A Anitha et al.

Journal of biomedical nanotechnology, 9(3), 335-347 (2013-04-30)

In the current work, a sustained drug delivery system of flutamide (FLT) was developed using chitosan (CS) and dextran sulphate (DS) nanoparticles and were characterized using different techniques. The prepared nanoparticles showed a size of 80-120 nm with an entrapment

Hemostasis disorders caused by polymer coated iron oxide nanoparticles.

Lamiaa M A Ali et al.

Journal of biomedical nanotechnology, 9(7), 1272-1285 (2013-08-06)

Superparamagnetic iron oxide nanoparticles (SPIONs) are inorganic nanomaterials gaining strong clinical interest due to their increasing number of biological and medical applications. The stabilization of SPIONs in a biocompatible stable suspension (bioferrofluid) is generally achieved by an adequate polymeric coating.

Recurrent laryngeal nerve transection and anastomosis: rat laryngeal motoneuron survival and effect of the anastomosis site.

Michael J Pitman et al.

The Annals of otology, rhinology, and laryngology, 122(4), 283-287 (2013-05-24)

We investigated the quantity of recurrent laryngeal nerve motoneurons (RLNMs) that survive after transection and anastomosis of the rat recurrent laryngeal nerve (RLN), as well as the impact of the anastomosis site on RLN regeneration. Ten rats underwent right RLN
