Insight in the osmotic behavior of degrading hydrogels is of great importance in the design of biodegradable hydrogels for biomedical applications. This study compares the degradation behavior of PEG-HEMA (hydroxyethylmethacrylated polyethylene glycol) and dex-HEMA (hydroxyethylmethacrylated dextran) hydrogels. The degradation of PEG-HEMA gels takes several months to over a year, while that of ...

Isolated giant varicocele has been reported with portal hypertension that results in abnormal communication between portal venous system and testicular vein venous system resulting in retrograde backflow of blood into the testicular venous system which leads to varicosity of the pampiniform plexuses. 65-year-old male with no past medical or surgical history presented to us with soft inguinoscro...

The aim of this study was to investigate the effect of high pressure CO(2) on the crosslinking of elastin-based polymers and the characteristics of the fabricated hydrogels. A hydrogel was fabricated by chemically crosslinking alpha-elastin with glutaraldehyde at high pressure CO(2). The effects of pressure, reaction time, and crosslinker concentration on the characteristics of the fabricated h...

In this paper, a simplified formulation for compositional reservoir simulator is presented. These types of simulators are used when inter-phase mass transfer depends on phase composition as well as pressure. The procedure for solving compositional model equations is completely described. For equilibrium calculation, property estimation Peng Robinson equation of state is used. This equation ...

Swelling of graphene oxide (GO) membranes and bulk graphite under confinement conditions is found to produce pressures up ?220 bar. pressure important take into account in many applications GO membranes, but it has not been previously reported. are typically measured only for materials. However, demonstrated that even µm thick develop 3–25 bar due the volume expansion caused by swelling water. ...

?Sir,?To-day a patient came to hospital with the following unusual appearance. There was profound swelling of the abdomen, back, chest, neck, and face, which everywhere crepitated under pressure of the fingers without pitting. History :?12 days ago, the patient, a male of 20 years, had a sudden attack of pain and swelling in the right iliac and inguinal regions accompanied with obstinate vomiti...
