In this study, the pregnant female Sprague Dawley (SD) rats were used to evaluate the potential toxicological effect of strontium citrate, a dietary supplement, on embryo-fetal development. Strontium citrate at doses of 0 mg/kg, 680 mg/kg, 1360 mg/kg, and 2267 mg/kg was administrated orally by gavage to rats at day 6 to day 15 of pregnancy. Each group contained 20 pregnant rats. On the 20th day of gestation, rats was anesthetized and dissected by cesarean section. The appearance, internal organs, gravid uterus weight, embryo implantation number, and implantation loss rate in maternal rats of each group did not reveal any lesions. In fetuses, there were no statistical differences in the fetus weight, sex ratio, embryo resorption number, stillbirth number, and fetal visceral examination in all testing groups compared to the control group. However, in 2267 mg/kg strontium citrate group, the fetuses showed the statistical differences in the anomalies of the bones and eyes compared to the control group. These findings indicate that high-dose strontium citrate possesses an adverse effect on embryonic and fetal development in SD rats. The no observed adverse effect level (NOAEL) of strontium citrate for prenatal development toxicity in SD rats may be regarded as 1360 mg/kg/day.

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Toxic Reactions: Overview01:26

Toxic Reactions: Overview

When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
