Oxygen transfer in the capillary fringe (CF) is of primary importance for a wide variety of biogeochemical processes occurring in shallow groundwater systems. In case of a fluctuating groundwater table two distinct mechanisms of oxygen transfer within the capillary zone can be identified: vertical predominantly diffusive mass flux of oxygen, and mass transfer between entrapped gas and groundwat...
Cross-linked nanoassemblies (CNAs) with a degradable core were prepared for sustained release of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), a potent inhibitor of heat shock protein 90 (HSP90). The particle size of CNAs ranged between 100 and 250 nm, which changed depending on the cross-linking yields and drug entrapment method. CNAs with a 1% cross-linking yield entrapped 17-AAG in aque...
A wide variety of enhanced and modified sol-gel bulk and thin film processes for the development of sensors and biosensors have been witnessed in the last two decades. The porous silica glass material prepared by the sol-gel process is a promising host matrix for the encapsulation of various biomolecules viz. proteins, antibodies, enzymes. The entrapped biomolecules have shown to retain their f...
The chronic cardiotoxicity of doxorubicin as a free drug or entrapped in positive and negative liposomes was morphologically evaluated in mice treated seven times i.v. at a dose of 4 mg/kg. Liposomes were composed of phosphatidylcholine, cholesterol, and stearylamine (positive charge) or phosphatidylserine (negative charge). Administration of free doxorubicin caused a pattern of cardiac damage ...
Introduction. In artificial hip joints, the roughening of the femoral head has been associated to higher wear rates of the polymeric cup, eventually leading to osteolysis and implant failure. The increase of the femoral head roughness is strongly influenced by the presence of abrasive particulate entrapped between the articulating surfaces (Bauer et al., 1994 and Raimondi et al., 2000). This da...
