We used a structural analogue of arginine vasopressin (AVP) and investigated the role of AVP in the maintenance of mean arterial pressure (AP) in anesthetized, water-deprived rats. The administration of [1(beta-mercapto-beta,beta-cyclopentamethylene propionic acid) 4-valine-8-D-arginine] vasopressin, d(CH2)5VDAVP, completely inhibited to 30-40 mma Hg rise in AP which normally accompanied the ad...

An instrument is described that provides a stable magnified image for ophthalmoscopy and a low power operating microscope combined to allow greatly improved fundal inspection and to eliminate the need to change instruments during detachment surgery.

Sealed surfaces in urban areas change the water and energy balance resulting decreased evapotranspiration infiltration, magnified stormwater runoff, sensible heat fluxes. Urban Green Infrastructures (UGI) are implemented to reverse such effects. This study examines potential of a high-resolution grid-based model show impact different degrees land cover. The area was divided into 52 cells were c...

A 32-year-old man presented with a floater in his right eye of 1-day duration. Examination revealed visual acuity 20/20 2 disc-diameter, pigmented, translucent, freely floating, oval cystic lesion the midvitreous (Fig A, inset showing magnified view). Ultrasonography highlighted nature an anechoic center and hyperechoic borders B) OCT well-defined hyperreflective structure hyporeflective lumen ...

One of the most direct routes for investigating the geometry of the Universe is provided by the numbers of strongly magnified gravitationally lensed galaxies as compared with those that are either weakly magnified or de-magnified. In the submillimetre waveband the relative abundance of strongly lensed galaxies is expected to be larger as compared with the optical or radio wavebands, both in the...

The most commonly used image magnification techniques are interpolation based: nearest neighbor, bilinear, and bicubic. The drawbacks of these traditional methods are that images magnified by the simple nearest neighbor method often appear “blocky,” while images magnified by linear and cubic interpolations usually appear “blurry.” In this work, a new technique, which improves the performance of...
