Risk Assessment Paradigms
Chapter 3 Risk Assessment Paradigms As defined, risk assessment is the qualitative or quantitative characterization and estimation of potential adverse health effects associated with exposure of individuals or populations to…
Minimum Reactants Required for Synthesis of Skin and Peripheral Nerves; Extension to Tissues of Other Organs
It is a report of the insoluble substances that went into the reactor (i.e., the anatomically well-defined defect) and the insoluble products that were eventually synthesized in it. Reaction diagram…
An Antagonistic Relation Between Wound Contraction and Regeneration
Fig. 8.1 Wounds close partly by contraction and regeneration in the tadpole; however, they close by contraction and scar formation in the adult frog. Photos of healing of full-thickness excisional…
Experimental Methods II. The Defect Closure Rule
In this example, the large difference in magnitude between the time constants suggests that the two processes (i.e., the developmental transition in healing outcome and the healing process) occur at…

Regeneration of Skin
Fig. 5.1 Structure of the intact basement membrane in skin. Top: Electron micrograph showing the two major layers comprising the basement membrane, lamina lucida (LL) and lamina densa (LD), that…
Nonregenerative Tissues
Fig. 2.1 The epidermis is a regenerative tissue. Following controlled injury (stripping or blistering), which leaves the dermis intact (left), the epidermis recovers its structure completely at the site of…
