Cleansing and care of the diaper area require special consideration to maintain barrier function of the skin in this area and repair the barrier when it is compromised. Diaper dermatitis occurs commonly; understanding and modification of predisposing factors are imperative for caregivers. In this paper, we review important factors in diaper area care, including skin pH, the local microbiome, ir...

objective(s):protective effects of diuretics, particularly of hydrochlorothiazide (hct), for the development of seizure attacksepilepsy have been described in vivo. however, itsthe mechanism of action of hct is unknownneeds to be elucidated. materials and methods: extracellular field potentials were recorded from the ca1- and ca3-subfields of the hippocampus of rats. epileptiform discharges wer...

cerebral palsy (cp) is the most common motor disability in children, usually occurring during fetal development; before, during, or shortly after birth, or during infancy. cp takes place in about 2.1 per 1,000 live births .there is no exact reason but birth injury or inflammation of the central nervous system, infections and hypoxia are related risk factors of this disease. often, symptoms incl...

The epidermal barrier varies over the body surface to accommodate regional environmental stresses. Regional skin barrier variation is produced by site-dependent epidermal differentiation from common keratinocyte precursors and often manifests as site-specific skin disease or irritation. There is strong evidence for body-site-dependent dermal programming of epidermal differentiation in which the...

BACKGROUND In implant dentistry, bone substitute materials and barrier membranes are used in different treatments including guided bone regeneration (GBR), socket preservation, alveolar ridge augmentation, maxillary sinus elevation, and filling bony defects around the inserted dental implant. One of the most important factors in prognosis of treatments using these materials is the growth of new...

the paper presents the results of an investigation on the acoustic performance of vertical profile parallel barriers with quadratic residue diffuser tops and faces. a 2d boundary element method (bem) is used to predict the barrier insertion loss. the results of rigid and with absorptive coverage are also calculated for comparisons. using qrd on the top surface and faces of all vertical profile ...

For terrestrial creatures, the water-impermeable barrier function of the skin is essential to maintain life in the face of environmental dryness. Stratum corneum, which plays a crucial role in the barrier function, is composed of two components, i.e., protein-rich nonviable cells and intercellular lipid domains. When the barrier function is damaged by a surfactant, organic solvent or tape strip...

The blood-prostate barrier could be the major factor that preventing delivery of drugs to prostate tissue and leads to the failure of treatment. Studies indicate that ultrasonic sonoporation can break the blood-prostate barrier and increase the concentration of drugs, but the mechanism is still unclear. Tight junctions exist widely in the endothelial and epithelial cells of mammalians, and form...

   Graphene oxide nanosheet (GONS) can be a suitable membrane for gas separation with high permeability and selectivity. Separation of N2/CO2 using functionalized GONS was investigated by molecular dynamics simulations. The simulated systems were comprised of two types of GONS with a pore in their center, N2 and CO2 molecules. The selectivity and ...
