Smart Magnetic Nanoaptamer: Construction, Subcellular Distribution, and Silencing HIF for Cancer Gene Therapy

ACS Biomaterials Science & Engineering, 2018
Attenuating the expression of HIF-1α (hypoxic inducible factor) by siRNA has an effect on the proliferation of hypoxia cancers. Mitochondria targeting siRNA may silence the level of HIF-1α for cancer gene therapy. A GAG-rich DNA was conjugated to GC-rich DNA for the synthesis of functional magnetic nanoaptamer (DNA-Fe3O4) to keep the innate character ...

Drum-like silencers using magnetic forces in a pressurized cavity

Journal of Sound and Vibration, 2006
A feasibility study is carried out for utilizing magnetic force to yield a low-frequency shift of the transmission loss spectrum provided by a drum-like silencer consisting of two side-branch, rectangular cavities covered by ferromagnetic membranes. The results show that the transmission loss spectrum of the drum-like silencer is mainly controlled by ...

Effects of pulsed magnetic field on neurons: Cnp signal silences a feed-forward network model

2013 6th International IEEE/EMBS Conference on Neural Engineering (NER), 2013
Several experimental results published in the literature showed that weak pulsed magnetic fields affected the response of the central nervous system. However, the specific biological mechanisms that regulate the observed behaviors are still unclear and further scientific investigation is required.

Linear Cu–OH–Cu: magnetic silence for dicopper(II) in trigonal bipyramidal coordination geometry

J. Chem. Soc., Chem. Commun., 1993
A dicopper(II)µ-hydroxo cryptate with trigonal bipyramidal copper coordination geometry and linear Cu–O(H)–Cu bridge exhibits virtual diamagnetism arising from efficient antiferromagnetic exchange between dz2 magnetic orbitals mediated via the 2pz orbital of the hydroxo bridge.

Abstract 3223: Magnetic resonance spectroscopic imaging of lactate in LDH-A silenced metastatic breast tumors

Cancer Research, 2012
Abstract Glucose and glutamine are the major carbon sources for rapidly proliferating tumors. They provide the precursors for proteins, lipids, and nucleic acids, and as well as metabolic-reducing capability (NADPH). Pyruvate is mainly derived from glucose and glutamine metabolism and can be converted to lactate by the lactate ...
