Summary
Stable calcium isotopes track bone health in children. Research explores factors influencing calcium retention for optimal skeletal growth during development.
Area of Science:
- Pediatric Bone Health
- Mineral Metabolism
- Calcium Isotopes
Background:
- Skeletal mineralization begins in utero and continues through adolescence.
- Increased calcium retention is crucial for bone deposition and growth during childhood and adolescence.
- Stable calcium isotopes are vital for non-invasively studying calcium physiology in young individuals.
Purpose of the Study:
- To characterize dynamic changes in calcium physiology from infancy through adolescence.
- To define calcium absorption and utilization in healthy and chronically ill children.
- To explore factors affecting mineral retention, bone turnover, and calcium flux.
Main Methods:
- Utilizing stable calcium isotopes to non-invasively assess calcium dynamics.
- Analyzing calcium absorption and utilization patterns.
- Investigating genetic and microbiome influences on calcium metabolism.
Main Results:
- Stable calcium isotope techniques have elucidated calcium dynamics in pediatric populations.
- Research is expanding to understand variability in mineral retention.
- Emerging research focuses on genetic and gut microbiome impacts on calcium dynamics.
Conclusions:
- Advances in stable calcium isotope research enhance understanding of pediatric calcium utilization.
- This knowledge is critical for maximizing bone acquisition during critical developmental stages.
- Future research will further define determinants of calcium dynamics for improved pediatric bone health.

Elements have a set number of protons that determines their atomic number (Z). For example, all atoms with eight protons are oxygen; however, the number of neutrons can vary for atoms of the same element. The sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are called isotopes. Elements can have multiple isotopes, for example, carbon-12, carbon-13, and carbon-14.

02:31Elements: Chemical Symbols and Isotopes
126.7K
A chemical symbol is an abbreviation used to indicate an element or an atom of an element. For example, the symbol for mercury is Hg. The same symbol is used to indicate one atom of mercury (microscopic domain) or to label a container of many atoms of the element mercury (macroscopic domain).
Some symbols are derived from the common English name of the element; others are abbreviations of the name in another language — Latin, Greek or German. For example, the symbol for aluminum (common name)...

In the early 1900s, English chemist Frederick Soddy realized that an element could have atoms with different masses that were chemically indistinguishable. These different types are called isotopes — atoms of the same element that differ in mass. Isotopes differ in mass because they have different numbers of neutrons but are chemically identical because they have the same number of protons. Soddy was awarded the Nobel Prize in Chemistry in 1921 for this discovery.

4.3K
Most elements exist in nature as a mixture of isotopes. The isotopes differ in weight due to their respective number of neutrons. The molecular weight of a molecule is different depending on the specific isotope of its elements involved. As a result, the mass spectrum of the molecule exhibits peaks from the same fragment at multiple positions. The positions of these mass signals depend on the mass differences between isotopes. Furthermore, the intensity of these signals is dependent on the...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
