TL;DR: The comparison of the two systems improves the understanding of the release mechanisms which may provide useful insights when designing medical textiles.
Abstract: Comparative Study of a Drug Release from a Textile to Skin Objective The achievement of a therapeutic dose of the hydrocortisone acetate (HCr) for coetaneous affections by using: i) a cyclodextrine derivative and ii) a hydrogel, in the systems fixing the drug on a textile material and then releases it in vitro towards the dermis under the action of a perspiration kit. Methods The formation of a temporary deposit of HCr on a cotton knitted fabric in the variants: 1) covalent grafting with monochloro triazinyl-beta-cyclodextrine (MCT-β-CD) by complexation in the hydrophobic cavity of the CD; 2) through the inclusion of Na2SO4 in ionic crosslinked chitosan-based hydrogel. Upon the release of HCr in vitro, a perspiration kit has been used. Results The two medicine release systems can release the therapeutic dose for coetaneous disorders. Conclusion The comparison of the two systems improves the understanding of the release mechanisms which may provide useful insights when designing medical textiles.

TL;DR: The clinical monitoring of the grafts and the histopathological examination demonstrated the regenerative potential of the bacterial cellulose–keratin scaffolds, under the test conditions.
Abstract: The study presents the preparation and characterization of new scaffolds based on bacterial cellulose and keratin hydrogel which were seeded with adipose stem cells. The bacterial cellulose was obtained by developing an Acetobacter xylinum culture and was visualized using SEM (scanning electron microscopy) and elementally determined through EDAX (dispersive X-ray analysis) tests. Keratin species (β–keratose and γ-keratose) was extracted by hydrolytic degradation from non-dyed human hair. SEM, EDAX and conductometric titration tests were performed for physical–chemical and morphological evaluation. Cytocompatibility tests performed in vitro confirmed the material non-toxic effect on cells. The scaffolds, with and without stem cells, were grafted on the burned wounds on the rabbit’s dorsal region and the grafts were monitored for 21 days after the application on the wounds. The clinical monitoring of the grafts and the histopathological examination demonstrated the regenerative potential of the bacterial cellulose–keratin scaffolds, under the test conditions.

TL;DR: Testing of some plant extracts such as Salvia officinalis, Thymus serpyllum, Pelargonium odoratissimum, Hedera helix, Ocimum basilicum, Levisticum officinale, Tagetes patula, Galium verum and different pesticides against an Erwinia amylovora strain isolated from quince dameged samples found a good antibacterial activity.
Abstract: The interest in management fire blight prevention and control increased considerably in last years due to pathogen spread almost throughout the country. The objective of this paper focuses on testing of some plant extracts such as Salvia officinalis, Thymus serpyllum, Pelargonium odoratissimum, Hedera helix, Ocimum basilicum, Levisticum officinale, Tagetes patula, Galium verum and different pesticides against an Erwinia amylovora strain isolated from quince dameged samples. In this study, the biological material was represented by quince shoots, harvested from pomological collection of "Vasile Adamachi" farm, which belongs to University of Agricultural Science and Veterinary Medicine Iasi. The research were performed in the Phytopathology laboratory. Following the experiment performed note that among the eight plant extracts a good antibacterial activity has Pelargonium odoratissimum, Ocimum basilicum and Salvia officinalis and of the three pesticides, Alcupral 50 PU. Contrary to expectations worst results were obtained after testing Aliette 80 WG and Hedera helix products. The results were estimated statisticaly, by performing ANOVA test.

TL;DR: Indoor concentration of fungal spores in the university laboratory and high school classroom were found to be higher as the international standards and has potential to develop adverse health effects to the occupants.
Abstract: The aim of this investigation was to monitor the densities and distribution of indoor airborne fungal spores that can cause an allergic response in three educational institutions placed in different location of Iasi City, Romania. Areas monitored were two lecture halls and one laboratory from the university campus, one classroom from a primary school and one from high school. Air samples from all location were taken using the Koch sedimentation method, which suppose that Petri dishes which contained potato-dextrose-agar (PDA) and peptone-glucose-agar (PGA) media in three different compositions (classic, with rose-bengal and with streptomycin) are exposed to room air for a 5-min period. Samples were collected from April to May 2009. A total of 333 microfungal colonies were counted on 90 plates. Identification of these showed 11 genera and 10 colonies of indeterminate spores from the indoor air samples. The identification of the fungi was made according to their microscopic properties and through references. The results showed that in all three locations were differences in the distribution of fungal genera, but Penicillium, Cladosporium and Aspergillus were the most prevalent fungal genera (43.8, 22.2 and 18.0% of the total, respectively). Indoor concentration of fungal spores in the university laboratory and high school classroom were found to be higher as the international standards and has potential to develop adverse health effects to the occupants.

TL;DR: The role of β-CD and its derivatives in the textile industry is summarized and some general physicochemical characteristics are presented, followed by its application in the areas of dyeing, finishing, and wastewater treatment.
Abstract: β-Cyclodextrin (β-CD) is an oligosaccharide composed of seven units of D-(+)-glucopyranose joined by α-1,4 bonds, which is obtained from starch. Its singular trunk conical shape organization, with a well-defined cavity, provides an adequate environment for several types of molecules to be included. Complexation changes the properties of the guest molecules and can increase their stability and bioavailability, protecting against degradation, and reducing their volatility. Thanks to its versatility, biocompatibility, and biodegradability, β-CD is widespread in many research and industrial applications. In this review, we summarize the role of β-CD and its derivatives in the textile industry. First, we present some general physicochemical characteristics, followed by its application in the areas of dyeing, finishing, and wastewater treatment. The review covers the role of β-CD as an auxiliary agent in dyeing, and as a matrix for dye adsorption until chemical modifications are applied as a finishing agent. Finally, new perspectives about its use in textiles, such as in smart materials for microbial control, are presented.
