Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

3.8K
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Study Designs in Epidemiology

702
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

5.5K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

5.6K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

255
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Roles of Electrolytes: Calcium and Phosphate01:27

Roles of Electrolytes: Calcium and Phosphate

961
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.
The calcium concentration in blood plasma is primarily...

Area of Science:

  • Nutrition Science
  • Public Health
  • Food Science

Background:

  • Low dietary calcium intake is prevalent globally, increasing risks for rickets, osteomalacia, and other health issues.
  • Meeting recommended calcium requirements is challenging, especially without dairy products.
  • Calcium fortification of culturally acceptable foods is a potential strategy to improve intake.

Purpose of the Study:

  • To review current calcium fortification efforts globally.
  • To identify lessons learned from existing calcium fortification programs.
  • To highlight challenges and areas for future research in calcium fortification.

Main Methods:

  • A landscape review of calcium fortification initiatives was conducted in 2019.
  • The review synthesized information on current practices, successes, and challenges.
  • Focus was placed on mandatory and voluntary fortification programs.

Main Results:

  • The United Kingdom is the only country with mandatory calcium fortification of wheat flour.
  • Voluntary fortification includes items like maize flour, rice, and water.
  • Programs often face challenges with qualified personnel, clear guidelines, regulation, monitoring, high premix costs, and reaching target populations.

Conclusions:

  • Calcium fortification can improve calcium intake, but effective implementation requires addressing systemic challenges.
  • Current evidence quality is often low, necessitating further rigorous evaluation.
  • Future research should focus on assessing the impact of calcium fortification programs, especially in diverse settings.
