Vitamin B12

Vitamin B12

Vitamin B12, also known as cobalamin, is a crucial nutrient that plays several important roles in the body. Here are some key points about B12:

Functions

  1. Red Blood Cell Formation: B12 is essential for the production of red blood cells, helping to prevent anemia.
  2. Nerve Health: It supports the maintenance of the myelin sheath, which protects nerves.
  3. DNA Synthesis: B12 is vital for proper DNA formation and cell division.
  4. Energy Production: It aids in the metabolism of fats and carbohydrates for energy.

Sources

  • Animal Products: Meat, fish, poultry, eggs, and dairy are primary sources.
  • Fortified Foods: Some plant-based foods and cereals are fortified with B12.
  • Supplements: Available in various forms, including tablets, sublinguals, and injections.

Deficiency

A deficiency can lead to symptoms like fatigue, weakness, nerve problems (tingling or numbness), and cognitive difficulties. Vegans and vegetarians are at higher risk since B12 is primarily found in animal products.

Recommendations

The recommended daily intake varies by age and life stage, but adults generally need about 2.4 micrograms per day. If you're concerned about your B12 levels, especially if you follow a plant-based diet, consider talking to a healthcare professional for advice on testing and supplementation.

Biochemistry plays in space exploration

  Biochemistry plays a critical role in space exploration by   helping to ensure the health and well-being of astronauts .   Space travel can have many negative effects on the human body, including: Bone and muscle loss Cardiovascular changes Weakened immune systems Hormonal imbalances Abnormal digestion and absorption Abnormal iron metabolism Ophthalmological issues   Biochemistry helps to develop strategies to counteract these effects. This includes:   Nutritional counter measures NASA's Nutritional & Biochemistry team develops and validates nutritional countermeasures to prevent or minimize the negative effects of spaceflight on the human body. For example, astronauts may need less iron during long-duration missions.   Understanding metabolic processes Understanding the impact of space travel on metabolic processes is vital for designing effective countermeasures.   Designing better equipment and technologies Understanding what happens...

Kidney function tests

  Kidney function tests  Kidney function tests are essential for assessing how well your kidneys are working.  1. Blood Tests: Serum Creatinine : Measures the level of creatinine, a waste product from muscle metabolism. Elevated levels may indicate impaired kidney function. Blood Urea Nitrogen (BUN) : Measures the amount of nitrogen in your blood from urea, another waste product. High levels can suggest kidney issues. Estimated Glomerular Filtration Rate (eGFR) : Calculated using serum creatinine, age, sex, and race. It estimates how well your kidneys are filtering blood. An eGFR below 60 may indicate kidney disease. 2. Urine Tests: Urinalysis : A dipstick test that checks for protein, blood, glucose, and other substances. Presence of protein (proteinuria) can indicate kidney damage. 24-Hour Urine Collection : Measures the total amount of waste products excreted in urine over 24 hours. This can help assess kidney function and detect kidney stones. 3. Imaging Tests: U...

Mpox

  Mpox(monkeypox) Mpox, previously known as monkeypox, is a viral illness caused by the monkeypox virus, a species of the genus  Orthopoxvirus . There are two distinct clades of the virus: clade I (with subclades Ia and Ib) and clade II (with subclades IIa and IIb). In 2022–2023 a global outbreak of mpox was caused by the clade IIb strain.  Mpox continues to be a threat today, and an upsurge of cases in the Democratic Republic of the Congo and other countries caused by clades Ia and Ib has raised concern. There are vaccines for mpox. Vaccination should be considered along with other public health interventions.  Common symptoms of mpox are a skin rash or mucosal lesions which can last 2–4 weeks accompanied by fever, headache, muscle aches, back pain, low energy and swollen lymph nodes.  Mpox can be transmitted through close contact with someone who has mpox, with contaminated materials, or with infected animals. During pregnancy, the virus may be passed to ...
