High Cholesterol Levels in the Blood: Hypercholesterolemia Niacin (Vitamin B3)

By SWA

Here is a detailed explanation:

Niacin (Vitamin B3)

  • Role in Cholesterol Management: Niacin is known for its ability to improve cholesterol levels. It works by inhibiting the synthesis of cholesterol and triglycerides in the liver, which results in lowered total cholesterol, low-density lipoprotein (LDL) cholesterol (often referred to as "bad" cholesterol), and triglycerides. Additionally, niacin can raise high-density lipoprotein (HDL) cholesterol (the "good" cholesterol).
  • Mechanism of Action: Niacin decreases the production of VLDL (very-low-density lipoprotein) by the liver, which leads to a reduction in LDL and triglycerides. It also enhances the breakdown of LDL.
  • Usage: Niacin is used in high doses (often much higher than the daily recommended dietary allowance) for its lipid-lowering effects. These doses can only be taken under medical supervision due to potential side effects, such as flushing, liver toxicity, and hyperglycemia.

Other Options:

  • Riboflavin (Vitamin B2)

    • Role: Riboflavin is essential for energy production and the metabolism of fats, drugs, and steroids. It is not directly involved in lowering cholesterol levels.

  • Pyridoxine (Vitamin B6)

    • Role: Pyridoxine is important for protein metabolism, the production of neurotransmitters, and the creation of red blood cells. It does not have a direct effect on cholesterol levels.

  • Folic Acid (Vitamin B9)

    • Role: Folic acid is crucial for DNA synthesis and repair, cell division, and growth. While it is important for heart health and reducing homocysteine levels (an amino acid associated with cardiovascular disease), it is not specifically used for lowering cholesterol.

Summary:

Niacin is the vitamin that can be used in high doses to treat hypercholesterolemia due to its direct effects on reducing LDL and triglycerides while raising HDL cholesterol. The other vitamins listed do not have a direct role in managing cholesterol levels.

Toxic Skin Condition Post-mRNA COVID-19 Vaccination

Identifying Severe Skin Conditions Post-Vaccination Following administration of the BioNTech mRNA vaccine, a small subset of individuals may develop severe and complex reactions. These reactions are often misdiagnosed or misunderstood due to their rarity and diverse presentation. This essay examines a case characterized by severe skin conditions, systemic symptoms, and complications such as hypercalcemia and crystal formation. It highlights the need for accurate diagnosis, holistic management, and increased awareness of these rare but significant vaccine-related adverse events. Initial Symptoms and Misdiagnoses Severe symptoms began shortly after the first dose of the BioNTech vaccine, initially presenting as petechiae, diagnosed by a rheumatologist. However, following the second dose, symptoms rapidly escalated, resulting in intense burning pain and thinning of the skin. The skin on the legs and thighs became paper-thin and could tear with the slightest touch, with the affected area e...

Dysferlin Protein: Key Roles, Genetic Locations

The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Is ME CFS connected to Spinal Muscular Atrophy (SMA) or Post Polio?

By SWA

Today, I understand why Spinal Muscular Atrophy (SMA) received little attention, particularly in the mid-50s. This complex and debilitating genetic illness was poorly understood, and patients' symptoms were often minimized or even dismissed. For more information, please visit the Spinal Muscular Atrophy (SMA) page on MalaCards . Even now, many neurologists lack detailed knowledge of SMA, and comprehensive examinations mentioned in research are rarely pursued. In 2008, while investigating permanent adrenal insufficiency, an MRI ordered by my endocrinologist unexpectedly revealed Chiari Malformation II. However, surgery in 2009 brought no improvement. In 2010, a DNA test showed a genetic marker in the ACTN3 gene: https://www.malacards.org/search/results?q=ACTN3%20gene%20and%20Spinal%20Muscular%20Atrophy%20(SMA) A 2015 MRI revealed ankylosing spondylitis, multiple Tarlov cysts, stenosis at L4 and L5, spinal canal narrowing, and widespread degenerative changes. Surgery on L4 and L5 ...
