Environment (biophysical): Environment}}Dermal equivalent: The dermal equivalent is an in vitro model of the dermal layer of skin. It is constructed by seeding dermal fibroblasts into a collagen gel.Gastrointestinal physiology: Gastrointestinal physiology is a branch of human physiology addressing the physical function of the gastrointestinal (GI) system. The major processes occurring in the GI system are that of motility, secretion, regulation, digestion and circulation.Actinic elastosis: Actinic elastosis, also known as solar elastosis is an accumulation of abnormal elastin (elastic tissue) in the dermis of the skin, or in the conjunctiva of the eye, which occurs as a result of the cumulative effects of prolonged and excessive sun exposure, a process known as photoaging.Absorption (skin): Skin absorption is a route by which substances can enter the body through the skin. Along with inhalation, ingestion and injection, dermal absorption is a route of exposure for toxic substances and route of administration for medication.List of Bratz charactersBiotextile: Biotextiles are structures composed of textile fibers designed for use in specific biological environments where their performance depends on biocompatibility and biostability with cells and biological fluids. Biotextiles include implantible devices such as surgical sutures, hernia repair fabrics, arterial grafts, artificial skin and parts of artificial hearts.Tour SignalUlcerative dermatitis: Ulcerative dermatitis is a skin disorder in rodents associated with bacterial growth often initiated by self-trauma due to a possible allergic response. Although other organisms can be involved, bacteria culture frequently shows Staphylococcus aureus.Skin and skin structure infection: A skin and skin structure infection (SSSI), also referred to as skin and soft tissue infection (SSTI) or acute bacterial skin and skin structure infection (ABSSSI), is an infection of skin and associated soft tissues (such as loose connective tissue and mucous membranes). The pathogen involved is usually a bacterial species.
