Skin is in constant evolution from the embryo state, reciprocal control between epidermis and neurons different ages of life little known. Our objective was to characterize epidermal neuronal interaction juvenile or adult using a new model re-innervated epidermis. Human sensory were obtained iPS cells, their differentiation functionality validated by observation morphology, markers expression, ...

Kinetics of phosphate adsorption by Ca/Cr layered double hydroxide (LDH) in a batch reactor was investigated this study. The kinetic experiments indicated that the sorption from synthetic feed solution synthesised LDH very fast, with over 98% removal being achieved within 5 min contact. Kinetic modeling process to different models (pseudo first order, pseudo second Elovich and intraparticle dif...

Abstract The incidence of venous thromboembolism (VTE) in cancer patients may have changed the past decade, possibly due to novel therapies, improved survival, and high-resolution imaging. Danish medical registries were used identify 499 092 with a first-time diagnosis between 1997 2017, who matched 1 497 276 comparison individuals without from general population. We computed cumulative inciden...

The adsorption equilibrium isotherms of five phenolic compounds from aqueous solutions onto granular activated carbon (GAC) were studied and modeled. Phenol (Ph), 2-chlorophenol (2-CP), 4-chlorophenol (4-CP), 2,4-dichlorophenol (DCP), and 2,4,6-trichlorophenol (TCP) were chosen for the adsorption tests. To predict the adsorption isotherms and to determine the characteristic parameters for proce...

Two modified chitosan derivatives were prepared in order to compare their adsorption properties for Hg(II) removal from aqueous solutions. The one chitosan adsorbent (CS) is only cross-linked with glutaraldehyde, while the other (CSm), which is magnetic, is cross-linked with glutaraldehyde and functionalized with magnetic nanoparticles (Fe₃O₄). Many possible interactions between materials and H...

Because biosorption is a low cost and effective method for treating metal-bearing wastewaters, understanding the process kinetics is relevant for design purposes. In the present study, the performance of the aquatic moss Fontinalis antipyretica for removing cadmium and lead from simulated wastewaters has been evaluated. Five kinetic models (first-order, pseudo-first-order, Elovich, modified Rit...
