BACKGROUND Allergic contact dermatitis (ACD) is a common clinical condition in industrialized countries and often causes occupational diseases. Animal model of contact sensitivity (CS) is commonly used to study ACD in mice and can be induced by skin application of haptens. It has been previously shown that CS is mediated by CD4(+) or CD(8+) T effector cells. More recently it was found that also...

Systemic contact dermatitis (SCD), better termed systemically reactivated allergic contact dermatitis, is a type of contact hypersensitivity reaction in which ingestion or other systemic exposure to a contact allergen occurs in an already sensitized person. Although the initial sensitizing exposure is usually by topical application, re-exposure by the oral, intravenous or inhalation routes can ...

Younger granite bodies form two arches, the western and eastern (WA, EA), which extend from south northwards Meatique, ophiolitic group-island arc rocks, to large older outcrop north. This paper concerns feasibility of exploration in El-Erediya-Ria El-Garah-El-Gidami-El-Missikat Y Gr regions. Fieldwork remote sensing, together with geochemical, petrochemical, mineralogical studies, are used sho...

acanthamoeba keratitis is a vision-threatening infection caused by pathogenic species of the genus acanthamoeba. in this study, 13 acanthamoeba keratitis cases were diagnosed among 52 keratitis patients. to confirm the identity of acanthamoeba at the genus level, a pcr-based method was used, and their pathogenic potential was determined using in vitro cytotoxicity assays on human corneal epithe...
