Usage of gloves for hair shampooing in German hairdressing salons
BACKGROUND Occupational skin disease caused by wet work is particularly common in employees in hairdressing salons. The objective of this paper was to determine the frequency of glove use for hair shampooing. METHODS Data on the usage of gloves for hair shampooing were collected by covert observations in four cross-sectional surveys of newly opened hairdressing salons located in Cologne. Meas...
متن کاملPolytetrahydrofuran cross-linked polystyrene resins for solid-phase organic synthesis.
Currently, divinylbenzene cross-linked polystyrene (DVB-PS) is the polymer of choice for use in solid-phase organic synthesis (SPOS). While much research has been directed toward the optimization of linker groups for the attachment of compounds to the polymer, the development of new polymers themselves has been relatively neglected. In an attempt to overcome the shortcomings of DVB-PS and to de...
متن کاملChemical processing and shampooing impact cortisol measured in human hair.
PURPOSE The assessment of cortisol in hair has gained popularity as a means to measure retrospective hypothalamic-pituitary-adrenal activity in a number of species; however, cortisol levels from human hair subjected to typical chemicals for cosmetic or hygienic purposes may be altered by the chemicals used. The purposed of this study was to determine if exposure of hair to chemical processing o...
متن کاملSelf-organization of keratin intermediate filaments into cross-linked networks
Keratins, the largest subgroup of intermediate filament (IF) proteins, form a network of 10-nm filaments built from type I/II heterodimers in epithelial cells. A major function of keratin IFs is to protect epithelial cells from mechanical stress. Like filamentous actin, keratin IFs must be cross-linked in vitro to achieve the high level of mechanical resilience characteristic of live cells. Ker...
متن کاملEquilibrium Swelling of Highly Cross-Linked Polymeric Resins
A modified expression for the change in chemical potential of a solvent, in a polymer network, due to isotropic swelling was obtained by substituting a non-Gaussian chain length probability distribution in Flory’s statistical analysis of rubber elasticity. The affine non-Gaussian expression for the free energy change due to elastic deformation was compared to both the traditional Flory and the ...
