A self-powered organic–inorganic p–n heterojunction deep ultraviolet (DUV) photodetector (PD) was fabricated based on the polymer poly(3,4-ethylene-dioxythiophene):polystyrene sulfonate (PEDOT:PSS), with an in situ transferred composite film PEDOT:PSS-nitrogen-doped graphene (NGr)-coated SnO2 microwire. At 0 V bias, responsivity spectra of these two PDs both had a broadband response range 200–4...

In contrast to mammals, lesioned axons in the zebrafish (ZF) optic nerve regenerate and restore vision. This correlates with the absence of the NogoA-specific N-terminal domains from the ZF nogo/rtn-4 (reticulon-4) gene that inhibits regeneration in mammals. However, mammalian nogo/rtn-4 carries a second inhibitory C-terminal domain, Nogo-66, being 70% identical with ZF-Nogo66. The present stud...

OBJECTIVE Restoration of normal glucose regulation (NGR) in people with prediabetes significantly decreases the risk of future diabetes. We sought to examine whether regression to NGR is also associated with a long-term decrease in cardiovascular disease (CVD) risk. RESEARCH DESIGN AND METHODS The Framingham (2008) score (as an estimate of the global 10-year CVD risk) and individual CVD risk ...

The blood-brain barrier (BBB) is the major clinical obstacle in the chemotherapeutic management of brain glioma. Here we synthesized a pH-sensitive dual-targeting doxorubicin (DOX) carrier to compromise tumor endothelial cells, enhance BBB transportation, and improve drug accumulation in glioma cells. The drug delivery system was constructed with polydopamine (PDA)-coated mesoporous silica nano...

In the adult mammalian central nervous system (CNS), growth of neuronal fibers is actively inhibited by myelin. The proteins myelin-associated glycoprotein (MAG), oligodendrocyte myelin glycoprotein (OMgP), and Nogo-66 have been identified as inhibitory components present in CNS myelin. All three proteins exert their inhibitory activity by binding to a neuronal receptor complex containing the N...

The Nogo-66 receptor (NgR) plays a critical role in restricting axon regeneration in the central nervous system. This inhibitory action is in part mediated by a neuronal receptor complex containing p75NTR, a multifunctional receptor also well known to trigger cell death upon binding to neurotrophins such as NGF. In the present study, we show that Pep4 and NEP1-40, which are two peptides derived...

Experiments on Alcator C-Mod have addressed several issues for the ITER 15 MA baseline scenario from 2009-2012. Rampup studies show ICRF can save significant V-s, and that an H-mode in the ramp can be utilized to save 50% more. ICRF modifications to li(1) are minimal, although the Te profile is peaked relative to ohmic in the plasma center, and alter sawtooth onset times. Rampdown studies show ...

Purpose: NGR-hTNF exploits the tumor-homing peptide asparagine-glycine-arginine (NGR) for selectively targeting TNF-a to an aminopeptidase N overexpressed on cancer endothelial cells. Preclinical synergism with cisplatin was displayed even at low doses. This study primarily aimed to explore the safety of low-dose NGR-hTNF combined with cisplatin in resistant/refractory malignancies. Secondary a...

After an acute central nervous system injury, axonal regeneration is limited as the result of a lack of neuronal intrinsic competence and the presence of extrinsic inhibitory signals. The injury fragments the myelin neuronal insulating layer, releasing extrinsic inhibitory molecules to signal through the neuronal membrane-bound Nogo receptor (NgR) complex. In this paper, we show that a neuronal...

Nogo is a novel myelin-associated inhibitor of neurite outgrowth which regulates stable neuronal connections during axonal regeneration following injury in the adult mammalian central nervous system (CNS). Because cytokines and neurotrophic factors play a key role in inflammation-related axonal regeneration, we investigated: (i) the constitutive expression of Nogo and the Nogo receptor (NgR) mR...
