Introduction Cholesterol is an extremely important sterol in the tissues of animals. It is an organic molecule and a type of lipid. It is a fat-like substance, which is waxy in texture, and found in all the cells of our body, as it is essential for carrying out many functions such as synthesis of hormones, synthesis of vitamin D and also acts as an integral structural component of the membranes…

Nitrogenous bisphosphonates act on bone metabolism by binding and blocking the enzyme farnesyl diphosphate synthase (FPPS) in the HMG-CoA reductase pathway (also known as the mevalonate pathway).[38] [...]

Disruption of the HMG CoA-reductase pathway at the level of FPPS prevents the formation of two metabolites (farnesol and geranylgeraniol) that are essential for connecting some small proteins to the cell membrane. This phenomenon is known as prenylation, and is important for proper sub-cellular protein trafficking (see "lipid-anchored protein" for the principles of this phenomenon).[40]

While inhibition of protein prenylation may affect many proteins found in an osteoclast, disruption to the lipid modification of Ras, Rho, Rac proteins has been speculated to underlie the effects of bisphosphonates. These proteins can affect both osteoclastogenesis, cell survival, and cytoskeletal dynamics. [...]

Statins are another class of drugs that inhibit the HMG-CoA reductase pathway. Unlike bisphosphonates, statins do not bind to bone surfaces with high affinity, and thus are not specific for bone. Nevertheless, some studies have reported a decreased rate of fracture (an indicator of osteoporosis) and/or an increased bone mineral density in statin users. The overall efficacy of statins in the treatment of osteoporosis remains controversial.[41]

Inherited disorders of cholesterol biosynthesis are a group of inherited metabolic disorders (IEMS) that affect the body's ability to produce cholesterol and other sterols. Because cholesterol plays a key role in cellular structure, signaling, and function, these disorders can lead to a variety of clinical manifestations. This group of disorders includes: Smith-Lemly-Opitz syndrome, desterolosis, Conradi-Hünermann-Happle syndrome, mevalonate kinase deficiency, Lathosterolosis, sitosterolemia, sterol C4-methyloxidase-like (SC4MOL) deficiency, familial hypercholesterolemia FH, cerebrotendinous xanthomatosis (CTX), and others. Cholesterol metabolism in the brain: Because disorders of cholesterol metabolism are often accompanied by central nervous system (CNS) pathology, it is important to consider some unique aspects of cholesterol metabolism in the brain. Unesterified cholesterol is an essential component of the plasma membrane of all cells, but is particularly high in brain cells. It is a major component of dense myelin, a specialized form of the plasma membrane of oligodendrocytes. Although the brain accounts for only about 2% of total body weight, brain cholesterol accounts for about 23% of the sterol content in mammals. It is distributed between the myelin sheath and the plasma membrane of neurons and glial cells. These diseases often manifest as developmental, neurological, and physical abnormalities. Early diagnosis and management are essential to improve outcomes, although treatment options may be limited and often focus on symptom relief and supportive care. Genetic counseling is also an important part of managing these diseases. In addition to evaluating the patient's development, the diagnosis of such diseases also requires analysis and evaluation in combination with the patient's family genetic history, skin abnormalities, heart, and liver abnormalities. After the evaluation and analysis, it is necessary to collect clues such as the patient's clinical manifestations and specific biochemical tests for genetic testing diagnosis.

Diagnosis of HIDS

Diagnosing HIDS involves a combination of clinical evaluation, laboratory tests, and genetic analysis. Key diagnostic steps include:

Clinical Evaluation: A thorough medical history and physical examination to assess the pattern and characteristics of fever episodes, as well as other symptoms such as rash, abdominal pain, and lymphadenopathy.

Laboratory Tests:

Elevated IgD Levels: Measurement of immunoglobulin D (IgD) levels in the blood. Elevated IgD levels are a hallmark of HIDS, although they may not be elevated in all patients, particularly infants.

Urinary Mevalonic Acid: Elevated levels of mevalonic acid in the urine during fever episodes can support the diagnosis of HIDS.

Inflammatory Markers: Elevated levels of acute-phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) during attacks.

Genetic Testing: Confirmatory diagnosis through genetic testing to identify mutations in the MVK gene. This test can definitively diagnose HIDS and distinguish it from other periodic fever syndromes.

Causes and Genetic Basis of HIDS

HIDS is caused by mutations in the MVK gene, located on chromosome 12. This gene encodes the enzyme mevalonate kinase, which is essential for the production of cholesterol and other important molecules. Mutations in the MVK gene lead to reduced enzyme activity and the accumulation of mevalonic acid and other intermediates, triggering inflammatory pathways.

HIDS follows an autosomal recessive inheritance pattern, meaning that an affected individual inherits two mutated copies of the MVK gene, one from each parent. Carriers, who have one normal and one mutated copy of the gene, typically do not show symptoms but can pass the mutation to their offspring.

Terpenoids have been reported to be the major component of essential oils for ages. They are derivatives of terpenes, which contain oxygen molecules. Terpenoids are synthesized through the mevalonate pathway in plant sources, while some terpenoids can be obtained from marine organisms [40]. Due to their structural diversity, terpenoids have a simple unifying feature, referred to as the isoprene rule. All terpenes have fundamental repeating five-carbon isoprene units.

What are the properties of retinol, and what does it do for the skin?

Retinol, also known as vitamin A1, is a fat-soluble vitamin in the vitamin A family that is found in food and used as a dietary supplement. As an ingredient in skincare products, it has several properties and benefits for the skin:

1. Promotes Skin Renewal:Retinol stimulates the renewal of skin cells by encouraging the production of new, healthy cells. This process can help improve the skin's texture, making it smoother and more youthful-looking.

2.Anti-Aging:Retinol is widely known for its anti-aging properties. It can help reduce the appearance of fine lines and wrinkles, making the skin look firmer and more youthful over time.

3. Improves Skin Tone:Retinol can even out skin tone by fading dark spots, sunspots, and hyperpigmentation. It can help create a more balanced and radiant complexion.

4.Treats Acne: Retinol is effective in treating acne because it helps prevent the clogging of pores. It can also reduce inflammation and improve overall skin health.

5. Boosts Collagen Production: Retinol stimulates collagen production in the skin. Collagen is a protein that provides structural support to the skin, making it more resilient and less prone to sagging.

6. Enhances Skin Hydration:While retinol can be drying for some individuals, it also has the potential to improve skin hydration by increasing cell turnover and allowing better absorption of moisturizers.

7. Reduces the Appearance of Large Pores: Retinol can help tighten and minimize the appearance of enlarged pores, giving the skin a smoother and more refined appearance.

8. Exfoliates the Skin:Retinol has exfoliating properties that can remove dead skin cells from the surface of the skin, leaving it looking brighter and more refreshed.

It's important to note that while retinol offers many benefits, it can also be potent and may cause skin sensitivity, redness, and peeling, especially when first introduced into a skincare routine. It is recommended to start with a lower concentration of retinol and gradually increase it to allow your skin to acclimate. Additionally, it should be used in combination with sunscreen during the day, as it can make the skin more sensitive to UV radiation.

In addition, there are now other anti-aging ingredients available, such as peptides, resveratrol, EOPE, and mevalonate sulfurin. These ingredients help combat aging without causing skin sensitivity, but they tend to be more expensive.
