Lens capsules become fibrotic after cataract extraction. A variety of extracellular matrix (ECM) components accumulate on these capsules in association with the proliferation of lens epithelial cells. To provide a better understanding of the process of capsular fibrosis, we assessed the types of proteoglycans (PG) in human lens capsules with intraocular lenses (IOL). Lens capsules containing IO...

~emistry of the crosslinking of gelatin is a complex phenomenon. the nature of which is dependent on several factors. The present manuscript represents an attempt to answer some specific basic science issues. Two "stress" conditions are commonly known in connection with gelatin capsules. The first condition is induced by exposure to formaldehyde. The second stress condition is created by exposi...

BACKGROUND AND AIMS Despite strong mechanistic data, and promising results from in vitro and animal studies, the ability of probiotic bacteria to improve blood pressure and serum lipid concentrations in humans remains uncertain. The aim of this study was to determine the effect of Lactobacillus acidophilus La5 and Bifidobacterium animalis subsp lactis Bb12, provided in either yoghurt or capsule...

Miltefosine, an effective oral treatment of visceral leishmaniasis (VL), was selected in May 2005, by the governments of India, Nepal, and Bangladesh for the elimination of VL. However, abnormally high treatment failure rates reported in patients in Bangladesh, given a miltefosine generic product ("Miltefos", Popular Pharmaceuticals Ltd.) during 2008, led the World Health Organization (WHO) to ...

We report polymer capsule-based probes for quantifying the pressure exerted by cells during capsule internalisation (Pin). Poly(methacrylic acid) (PMA) capsules with tuneable mechanical properties were fabricated through layer-by-layer assembly. The Pin was quantified by correlating the cell-induced deformation with the ex situ osmotically induced deformation of the polymer capsules. Ultimately...

The hydrophobic-amphiphilic self-assembly approach has been employed to prepare molecular micro-capsules simply by cooling down an emulsion, in a hot polar solvent medium, of a melted compound having two very well-distinguished units, both with highly non-polar and hydrophobic characteristics. The resulting micro-capsules are very stable and robust both in suspension and under dry conditions. F...

We present a novel method for remote release of an encapsulated material from polyelectrolyte capsules based on laser light illumination. Two different components were introduced in the polyelectrolyte shells of PAH/PSS capsules-either Ag nanoparticles or IR dye-to induce absorption of light. Under laser illumination the capsules containing Ag nanoparticles or IR dye were deformed or cut, thus ...
