Polymeric micelle nanocarriers in cancer research

Dae Hwan Shin, Yu Tong Tam, Glen S. Kwon

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 3,   Pages 348-359 doi: 10.1007/s11705-016-1582-2

Abstract: Amphiphilic block copolymers (ABCs) assemble into a spherical nanoscopic supramolecular core/shell nanostructure termed a polymeric micelle that has been widely researched as an injectable nanocarrier for poorly water-soluble anticancer agents. The aim of this review article is to update progress in the field of drug delivery towards clinical trials, highlighting advances in polymeric micelles used for drug solubilization, reduced off-target toxicity and tumor targeting by the enhanced permeability and retention (EPR) effect. Polymeric micelles vary in stability in blood and drug release rate, and accordingly play different but key roles in drug delivery. For intravenous (IV) infusion, polymeric micelles that disassemble in blood and rapidly release poorly water-soluble anticancer agent such as paclitaxel have been used for drug solubilization, safety and the distinct possibility of toxicity reduction relative to existing solubilizing agents, e.g., Cremophor EL. Stable polymeric micelles are long-circulating in blood and reduce distribution to non-target tissue, lowering off-target toxicity. Further, they participate in the EPR effect in murine tumor models. In summary, polymeric micelles act as injectable nanocarriers for poorly water-soluble anticancer agents, achieving reduced toxicity and targeting tumors by the EPR effect.

Acid resistance of methanogenic bacteria in a two-stage anaerobic process treating high concentration

ZHOU Xuefei, REN Nanqi

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 53-56 doi: 10.1007/s11783-007-0010-8

Abstract: The acid resistance of granular sludge and methanogenic bacteria and their metabolizing activity wereApparently, these were not the advisable pH levels that common methanogenic bacteria could accept.The methanogenic bacteria of the system, viz.Methanosarcina barkeri, had some acid resistance and could still degrade methanol at pH 5.0.If the methanogenic bacteria were trained further, their acid resistance would be improved somewhat.

Abstract: The aim of this study was to investigate the uptake of two organic phosphorus compounds (phytic acidand D-glucose-6-phosphate) by freshwater bacteria.One experiment suggested that phytic acid (refractory) could displace phosphate from the biofilm surfaceexperiment showed that D-glucose-6-phosphate (labile) could be hydrolysed and utilized easily by the bacteriaThe results also suggested that bacteria might break down the C-P bonds to utilize the carbon.
