Aging and Insulin Resistance: Just Say iNOS [PDF]

Diabetes, 2013
The ubiquitous presence of insulin resistance cannot be understated. First brought to light by Himsworth and Kerr (1) in 1939, insulin resistance, defined as a subnormal response to a given dose of insulin, was ushered into prime time by Gerald Reaven (2), where it has remained at center stage.

Off equilibrium fluctuations in a polymer glass [PDF]

, 2005
The fluctuation-dissipation relation (FDR) is measured on the dielectric properties a polymer glass (polycarbonate). It is observed that the fluctuation dissipation theorem is strongly violated for a quench from above to below the glass transition ...

Chemical, Mechanical and Tribological Effects of Artificially Aging up to 6 Weeks on Virgin and Crosslinked UHMWPE Evaluated for a TKR Design

Bioengineering
Patients undergo total knee arthroplasty (TKA) at younger ages with the expectation that the devices will perform well over two to three decades. During this time, the ultra-high molecular weight polyethylene (UHMWPE) bearing material properties of the ...

Effect of Creep Aging Process on Microstructures and Properties of the Retrogressed Al-Zn-Mg-Cu Alloy

Metals, 2016
The creep aging behaviors of retrogressed Al-Zn-Mg-Cu alloy were studied by uniaxial tensile creep tests at 140 °C. The effects of creep aging time and applied stress on microstructures and properties of the studied alloy were investigated by using ...

Longevity Genes: From Primitive Organisms to Humans [PDF]

, 2002
A variety of lines of evidence indicate that aging and longevity are subject to genetic regulation, but until fairly recently the identity of these genes was unknown. This has changed dramatically over the last ten years.

Aging process of electrical contacts in granular matter

, 2003
The electrical resistance decay of a metallic granular packing has been measured as a function of time. This measurement gives information about the size of the conducting cluster formed by the well connected grains. Several regimes have been encountered.
