Membranes for Artificial Kidney

Kobunshi, 1972
人工腎に用いられる膜は,その発祥から現在に至るまで一貫してセルロース膜である。この王座は当分動きそうにない。ではいまのcuprophane膜に満足しているのかといえば,決してそうではない。透過性・強度いずれの点でも不満が多い。他の膜が提供されないから, できの悪いcuprophaneでガマンしているというのが現状である。新しい膜を開発する研究も数多く行なわれている。どれも実用化に至らないのは, 個々の点ですぐれていても総合点になるとcuprophaneより卓越したものがないからである。透過性の点はともかく, ダイアライザーという特殊構造に組み入れられたときの機械的強度に難点のあることが多い。新しい膜の中で実用化に近い点まで達しているのは,いずれも天然高分子(セルロース, コラーゲン) の膜である ...

Digalactosyl-diacylglycerol-deficiency lowers the thermal stability of thylakoid membranes [PDF]

, 2010
We investigated the effects of digalactosyl-diacylglycerol (DGDG) on the organization and thermal stability of thylakoid membranes, using wild-type Arabidopsis thaliana and the DGDG-deficient mutant, dgd1. Circular-dichroism measurements reveal that DGDG-

Electrocapillary Modulated Interfacial Tension Amplifies Liquid Metal Transduction

Advanced Functional Materials, EarlyView.
This study presented an electrocapillary‐enhanced magnetohydrodynamic pumping strategy that harnesses the Lorentz force and interfacial tension modulation of liquid metal droplets to achieve amplified fluidic power. The system enabled low‐voltage, self‐oscillating fluidic transduction with enhanced pressure and flow generation, supporting compact ...

Endodontic surgery with bone graft: apicoectomy of left maxilar lateral incisor

RGO: Revista Gaúcha de Odontologia
In cases where endodontic treatment is unsuccessful, endodontic retreatment is usually the first option for clinical management. However, it is possible for periapical infection to persist. Eventually, these apical infections reach inaccessible locations,

Freestanding Artificial Synapses Based on Laterally Proton-Coupled Transistors on Chitosan Membranes

, 2015
Freestanding synaptic transistors are fabricated on solution-processed chitosan membranes. A short-term memory to long-term memory transition is observed due to proton-related electrochemical doping under repeated pulse stimulus.
