Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Systemic silencing signal(s)

Plant Molecular Biology, 2000
Grafting experiments have revealed that transgenic plants that undergo co-suppression of homologous transgenes and endogenous genes or PTGS of exogenous transgenes produce a sequence-specific systemic silencing signal that is able to propagate from cell to cell and at long distance.

Aircraft Signal Systems

Transactions of the American Institute of Electrical Engineers, 1944
Because the selection of aircraft warning devices has not, in most signal installations, provided the pilot with dependable warnings of dangerous conditions, this paper proposes that aircraft signal devices should be designed and stalled in compliance with the pilot's requirements as expressed in three design principles.

BINAURAL SIGNAL ENHANCEMENT SYSTEM

The Journal of the Acoustical Society of America, 2008
A signal processing system, such as a hearing aid system, adapted to enhance binaural input signals is provided. The signal processing system is essentially a system with a first signal channel having a first filter and a second signal channel having a second filter for processing first and second channel inputs and producing first and second channel ...

Signalling system requirements

IET Seminar on Power Distribution for Signalling Systems, 2007
Railway signalling equipment has evolved from a purely mechanical process operated by humans to one reliant on electricity to deliver safety to passengers and trains. The signal engineer has crafted electricity distribution systems to meet the challenges of basic electrical technology which has stood the test of time but has sometimes given rise to ...

Signal enhancement system

The Journal of the Acoustical Society of America, 1979
A signal enhancement method and apparatus including a computer arranged to process underwater signals at discrete spectral intervals for facilitating spectral signature recognition of submarines. An average of the spectral intensities of broadband noise on either side of the discrete spectral interval is computed and then subtracted from the spectral ...
