A number of studies have suggested that hypertension affects the pathogenesis of inflammatory reactions in various organs. The objective of this study was to evaluate the effects of hypertension on leukocyte-endothelial interactions after transient retinal ischemia. Transient retinal ischemia was induced for 60 minutes in spontaneously hypertensive rats (SHR) and in age-matched normotensive Wis...

The protein l-isoaspartate (d-aspartate) O-methyltransferase (E.C. 2. 1.1.77) can initiate the conversion of isomerized and racemized aspartyl residues to their normal l-aspartyl forms and has therefore been hypothesized to function as a repair enzyme, responsible for helping to limit the accumulation of damaged proteins in aging organisms. In this study, the effect of a disruption in the pcm-1...

leave : provided that, if on the first occasion on which he takes leave after January 1st, 1919, he combines with other leave privilege leave to a less amount than stands to his credit, the balance of the privilege leave at his credit will lapse, and he will not be entitled to enjoy it on a subsequent occasion. The total amount of privilege leave to be enjoyed under this clause on the second oc...

The fatigue life of structural details in the double side a tanker ship was investigated, employing spectral analysis approach. stochastic environmental loads were derived by seakeeping software based on 3D diffraction theory, frequency domain, and then mapped finite element model for hull. stress response at considered extracted from accumulated damage estimated Palmgren-Miner's rule. reductio...

We develop a thermodynamic framework for modeling nonlinear ultrasonic damage sensing and prognosis in materials undergoing progressive damage. The framework is based on the internal variable approach and relies on the construction of a pseudo-elastic strain energy function that captures the energetics associated with the damage progression. The pseudo-elastic strain energy function is composed...

One of the strongest risk factors for skin cancer is direct exposure to sun. Sunlight emits ultraviolet (UV) radiation, which can damage DNA cells in our bodies. UV causes mutations DNA, and these accumulated lead cancer. Melanin a pigment present that gives its color. also helps protect against radiation sun damage. In addition protective effects skin, most damaging from filtered out by Earth’...

The available fatigue theories have been examined using simple specimens subjected to bending or tension-compression loads. Therefore, the stress fields have been generally one or two dimensional. Anti-roll bar is a component belongs to the suspension system of the vehicles. In spite of having simple circular section, due to the having several curvatures, this component experiences a three-dime...

Synthetic hormones and bioactive substances (vitamins, pigments and isoflavons) which have been used in the feed industry are accumulated in milk, meat and eggs. It is suspected that these are responsible for a number of side-effects such as carcinogenesis, liver and kidney damage, allergies in consumers. Furthermore the synthetic hormones, vitamins, pigments are less active than those extracte...

The sea urchin, Sterechinus neumayeri, has a circumpolar distribution and is an abundant species in benthic communities of the Antarctic. Reproduction occurs during austral spring, when ozone concentrations over the past 25 years have been reduced by 50% or more, potentially exposing the planktonic embryos and larvae to elevated levels of UVB. During spring of 1996, cultures of S. neumayeri emb...
