Physiological adaptation of invasive plant Erigeron philadelphicus to different environments

open access: yes浙江大学学报. 农业与生命科学版, 2008
Erigeron philadelphicus is a new plant invader in the suburb of Shanghai. In order to understand better its physiological adaptability to different stresses, the relative membrane permeability, the concentrations of malonaldehyde (MDA), free proline ...

Experimental study of the effects of hypochlorite on polysulfone membrane properties [PDF]

open access: yes, 2006
Although chemical solutions are widely employed to clean membranes, they can also be responsible for changes in membrane properties. The two major drawbacks are then either the functional properties of the membrane gradually change, so the production can

Permeability across lipid membranes

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2016
Molecular permeation through lipid membranes is a fundamental biological process that is important for small neutral molecules and drug molecules. Precise characterization of free energy surface and diffusion coefficients along the permeation pathway is required in order to predict molecular permeability and elucidate the molecular mechanisms of ...

CORRELATION BETWEEN POLYMER PACKING AND GAS TRANSPORT PROPERTIES FOR CO2/N2 SEPARATION IN GLASSY FLUORINATED POLYIMIDE MEMBRANE [PDF]

open access: yesJournal of Engineering Science and Technology, 2016
Gas separation performance of a membrane highly hinges on its physical properties. In this study, the interplay between polymer packing of a membrane and its gas transport behaviours (permeability and selectivity) was investigated through a series of ...

細胞膜プレートを使用したサイトプローブ薬物の細胞膜透過性に関する基礎的検討 [PDF]

open access: yes, 2009
Drug efficacy depends on the amount of a preparation reaching the target tissue (grade of tissue transfer). In this experiment, we established the normal albumin concentration of a healthy adult (600 μ M) or a low-albumin state indicating marked liver ...
