clinicopathological report of three cases of opacification in hydrophilic acrylic intraocular lenses
purpose : to report clinical and pathological features of three cases of opacification with hydrophilic acrylic intraocular lenses (iols) case reports : in this interventional case report, we introduce the surgical and laboratory information about three hydrophilic acrylic iols which calcified after implantation for these patients with cataract. these lenses were explanted and analyzed with opt...
the formulation of hydrophobic drugs for oral drug delivery is challenging due to poor solubility, poor dissolution and poor wetting of these drugs. consequently, the aim of this study was to improve the dissolution of a model poorly water soluble drug, ibuprofen. microparticles containing ibuprofen were produced by spray drying and spray chilling technology in the absence/presence of a hydroph...
Abstract Mixed micellar systems have been tried with the aim of achieving higher solubility drugs compared to single systems. Hydrophobic-hydrophilic mixed used for above purpose drug ciprofloxacin in past. In present study, a hydrophilic-hydrophilic binary system comprising pluronic copolymers F127 and L64 has studied its effect on solubilization Ciprofloxacin. The solutions two individual the...
The stochastic nature of single-molecule charge transport measurements requires collection of large data sets to capture the full complexity of a molecular system. Data analysis is then guided by certain expectations, for example, a plateau feature in the tunnelling current distance trace, and the molecular conductance extracted from suitable histogram analysis. However, differences in molecula...
The structure of water confined in nanometer-sized cavities is important because, at this scale, a large fraction of hydrogen bonds can be perturbed by interaction with the confining walls. Unusual fluidity properties can thus be expected in the narrow pores, leading to new phenomena like the enhanced fluidity reported in carbon nanotubes. Crystalline mica and amorphous silicon dioxide are hydr...
Vibrationally resonant sum-frequency generation (VR-SFG) has been used to characterize the molecular orientation of the phenyl groups at the interface between polystyrene (PS) films and surface-modified glass substrates. Both the interface structure and the film adhesion are found to vary as the substrate surface is changed from hydrophobic to hydrophilic. The improved adhesion on the hydrophil...
