– Phononless plasmon assisted transport through a long disordered array of finite length quantum wires is investigated analytically. Generically strong electron plasmon interaction in quantum wires results in a qualitative change of the temperature dependence of thermally activated resistance in comparison to phonon assisted transport. At high temperatures, the thermally activated resistance is...

Contracting skeletal muscles acutely increases glucose transport in both healthy individuals and in people with Type 2 diabetes, and regular physical exercise is a cornerstone in the treatment of the disease. Glucose transport in skeletal muscle is dependent on the translocation of GLUT4 glucose transporters to the cell surface. It has long been believed that there are two major signaling mecha...

Retrograde axonal transport requires an intricate interaction between the dynein motor and its cargo. What mediates this interaction is largely unknown. Using forward genetics and a novel in vivo imaging approach, we identified JNK-interacting protein 3 (Jip3) as a direct mediator of dynein-based retrograde transport of activated (phosphorylated) c-Jun N-terminal Kinase (JNK) and lysosomes. Zeb...

V H(+)-ATPase has an important role in a variety of key physiological processes. This enzyme is reversibly activated/partly inactivated by the addition/exhaustion of extracellular glucose. The current model of its regulation assumes the reversible disassembly/reassembly of ∼60-70% of the V1 and V0 membrane complexes, which are responsible for ATP hydrolysis and H(+) conductance, respectively. T...

The endothelial vacuolar and vesicular transports in traumatic human brain oedema have been reviewed and compared with experimental brain oedema in order to establish their role in both oedema formation and oedema resolution. Normal or "non-activated" and "activated" capillaries are found. The activated capillaries showed predominantly an enhanced abluminally orientated vesicular transport by m...

The two stable isotopes of hydrogen, protium (1H) and deuterium (2H) differ in their physicochemical nature. Deuterium-depleted water (DDW) significantly inhibited the growth rate of different tumor cell lines in culture media and xenotransplanted MDA-MB-231, MCF-7 human breast adenocarcinomas and PC-3 human prostate tumors in vivo. The apoptosis-triggering effect of DDW was demonstrat...

We report on a theoretical study of spin-dependent electron transport through single-helical molecules connected by two nonmagnetic electrodes, and explain the experiment of significant spin-selective phenomenon observed in α-helical protein and the contradictory results between the protein and single-stranded DNA. Our results reveal that the α-helical protein is an efficient spin filter and th...

Polycrystalline thin films of Bi 2 Te 3 , a well-known topological insulator (TI), grown by RF sputtering shows metallic-like transport for wide range temperatures, T = 50 K to 225 K. For > K, the sample activated transport.. The behavior at low temperatures can be understood within model overlapping surface states TI nanocrystallites in film, suggesting that polycrystalline nature may also ...

Apseudohomogeneous model of the nitrifying activated sludge process was developed to investigate the effects ofmass-transport resistance and heterotrophic/nitrifier competition on the apparent relationship between dissolved oxygen (DO) concentration and nitrification . The kinetics of both heterotrophic carbon oxidation and autotrophic ammonia oxidation within activated sludge flocs were descri...
