Encapsulated healing agents is a promising solution for extending the service life of critical infrastructure, providing long-term efficiency. This research focuses on shell properties cement-based spherical macro-capsules, aiming to achieve increased survivability during mixing mortar mixtures and efficient triggering upon crack propagation. In this framework, pan coating technique was examine...

The shell dissolution properties of gelatine, gelatine/polyethylene glycol (PEG) and hydroxypropyl methylcellulose (HPMC) capsules were studied as a function of temperature, dissolution medium, and after different storage conditions. In any dissolution medium with a pH below or equal to 5.8, HPMC capsule shells dissolved rapidly, and there was no difference in the time in which dissolution occu...

Membrane chromatography (MC) is gaining wider acceptance in downstream processing of biopharmaceuticals. MC offers the advantage of higher operational flow-rates and thus, provides an attractive alternative to traditionally employed packed bed chromatography. With increased commercial usage, in-depth understanding of different mechanisms within MC capsules is desirable in order to achieve optim...

actively expressed in circulating neutrophils are those which are either subject to rapid turnover (i.e. those of the contractile machinery and membrane receptors) or those whose rate of biosynthesis needs to be increased during inflammation. It does not appear that mature cells actively synthesize, or upregulate during ‘priming’, those components normally present in high concentrations and/or ...

Vibrio cholerae, the causative agent of cholera, has the ability to grow and survive in the aquatic free-living amoeba Acanthamoeba castellanii. The aim of the present study was to examine the ability of the clinical isolate V. cholerae O139 MO10 to grow in A. castellanii and to determine the effect of the bacterial capsule and LPS O side chain on intracellular growth. Results from co-cultivati...

It has been discovered that, in addition to bacterial cells being stained a very dark brown or black color by Fontana's procedure, bacterial capsules are differentially stained a light brown color. Fontana (Dermatol. Wochschr., 55, 1003, 1912 and Pathologica, Genova, 4, 582, 1912) described a method for staining Treponema pallidum and other spirochetes by the AgNO3NH40H method. A similar proced...
