Hypoallergenic surgical tapes are generally considered hypoallergic in nature as their commercial trademarks suggest. However, we report a case of a patient, after receiving therapeutic laparoscopy, developing symptoms and signs suggestive of not allergic but irritant contact dermatitis in the recovery room after an uneventful general anesthetic course. Hypoallergenic Micropore Surgical Tape (3...

Contact between human neutrophils and aggregated immunoglobulin G bound to micropore filters has been studied as a model of the pathogenesis of tissue damage in immune complex disease. Contact with this surface, as well as with plain filters and polystyrene petri dishes, induced neutrophils to elaborate superoxide anion and hydrogen peroxide and to generate chemiluminescence, which has been att...

Equipping wastes with interesting properties in response to the circular economy could release environmental burdens by reducing resource exploitation and material manufacturing. In this study, we demonstrated that waste regenerated activated carbon (RAC) become micro-/mesopore-dominant through a simple surfactant/gel modification. This was achieved associating precursors, such as commercially ...

We have used a mouse monoclonal antibody (31D8) to determine whether differences in neutrophil (PMN) subpopulations might help explain decreased PMN chemotaxis in neonates compared with that of adults. 31D8 has been shown to bind heterogeneously to adult PMNs. Approximately 80% of the PMNs that strongly bind 31D8 (31D8 "bright") are the same cells that depolarize and migrate chemotactically whe...

The regulation of expression of the intestinal low density lipoprotein (LDL) receptor by luminal (apical) sterol flux was investigated in the human intestinal cell line CaCo-2. Cells were cultured on semipermeable micropore filters, which separated an upper and lower well. To the apical media were added solutions containing either taurocholate micelles alone or micelles containing sterols. Beca...

In this work, the formation of transient microporosity during polymer-to-ceramic conversion in polymer-derived ceramics was studied using a commercially available poly(vinyl)silazane precursor which modified with divinylbenzene (DVB) as linker molecule crosslinking. After pyrolysis treatments between 400 and 700 °C, resulting materials not only showed distinct changes elemental composition stru...
