The action of electrical stimulation of one of the pallial nerves on the sensitivity of the bursting RPa1 neuron of Helix pomatia to acetylcholine (ACh) was investigated. The depolarizing effect of ACh was significantly decreased by presynaptic stimulation. Stimulation leads also to an attenuation of the ACh-induced increase in membrane conductivity. The effect of stimulation on the ACh evoked ...

Abstract The smart membrane is a new type of functional membrane. performance this changed according to the variations in external physical and chemical signals. This has become an essential focus specific recognition, catalysis, selective permeation, other fields. However, problems are weak anti-pollution ability, poor response performance, inability mass production. Therefore, scholars have d...

Anion exchange membrane fuel cells (AEMFCs) are important alternatives to proton (PEMFCs). However, AEMFCs involve slow hydrogen oxidation reaction (HOR) on the anode. Catalysts improve HOR were developed by control of ruthenium nanoparticle size, alloying with iridium, and surface modification metal nanoparticles, resulting in enhanced catalytic activity optimizing binding energy bifunctionali...

The cellular functions of many eukaryotic membrane proteins, including the vasopressin-regulated water channel aquaporin-2 (AQP2), are regulated by posttranslational modifications. In this article, we discuss the experimental discoveries that have advanced our understanding of how posttranslational modifications affect AQP2 function, especially as they relate to the role of AQP2 in the kidney. ...

A simple and reproducible method for altering the acyl chain composition of Chinese hamster ovary cell phospholipids is described. By supplementation of the medium with 5% delipidized serum and 12 pg/ml of various fatty acids, extensive incorporation of the added fatty acid into membrane phospholipids was obtained. No significant changes in the phospholipid head group composition or the sterol/...

Figure 1: Experimental approach. Graft PEG to membrane surface to help reduce fouling of hydrophobic solutes [3]. Desalination can be used as a means to replenish freshwater supplies of communities with growing population needs. Reverse osmosis (RO) is a pressure-driven process that requires a semi-permeable membrane to selectively remove salts and other particulate matter from brackish water o...
