The term developmental toxicity has widely replaced the early term for the study of primarily structural congenital abnormalities, teratology, to enable inclusion of a more diverse spectrum of congenital disorders. The substances that cause developmental toxicity from embryonic stage to birth are called teratogens. The effect of the ...
An early life stage (ELS) test is a chronic toxicity test using sensitive early life stages like embryos or larvae to predict the effects of toxicants on organisms. [1] ELS tests were developed to be quicker and more cost-efficient than full life-cycle tests, taking on average 1–5 months to complete compared to 6–12 months for a life-cycle test.
By comparing a child’s development to the developmental age ranges in this tool, it allows providers to identify young children with developmental problems so that they can be referred for help. The tests address four domains of child development : personal-social (for example, waves bye-bye), fine motor and adaptive (puts block in cup ...
Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology caused by teratogens and also in pharmacology and toxicology.
The Battelle Developmental Inventory is a clinical-administered assessment that measures mastery of developmental milestones in the global domains of communication, social-emotional, adaptive, motor, and cognitive development. It is appropriate for use with children from birth to 7 years, 11 months. This assessment is published by Riverside ...
The Bayley Scales of Infant and Toddler Development (version 4 was released September 2019) is a standard series of measurements originally developed by psychologist Nancy Bayley used primarily to assess the development of infants and toddlers, ages 1–42 months. [1]
Category 1 has two subcategories for reproductive and developmental effects. Materials which cause concern for the health of breastfed children have a separate category: effects on or via Lactation. Specific target organ toxicity (STOT) [8] category distinguishes between single and repeated exposure for Target Organ Effects. All significant ...
The Gesell Developmental Schedules are a set of developmental metrics which outline the ages & stages of development in young children developed by Dr. Arnold Gesell and colleagues. [1] The original scale is generally considered not to satisfy the standards of rigor currently accepted in the field of psychometrics and is no longer used as an ...
