まとめ
血清アルカリフォスファターゼ (ALP) の上昇は,特にBMIが25以上の患者で,サルコーペニアのリスクが高いと関連しています. ALPのモニタリングと身体活動の参加は,サルコペニアのリスクを減らすのに役立ちます.
科学分野:
- 生物化学

主な方法:
- 6098人の成人を対象とした全国保健栄養調査 (NHANES) のデータ (2011-2018) を利用した横断的な研究.
- 血清ALPは生化学検査で測定され,サルコペニアはBMIに調整された尾筋質量で評価された.
- 関連性を決定するために,加重ロジスティック回帰,制限された立方スプレイン,および分層分析が使用されました.
主要な成果:
- 血清ALP値の上昇は,サルコペニアと有意に正の相関関係にあった.
- 最も高いALP四分位に属する個人は,最も低い四分位に比べて,サルコペニアのリスクが1. 96倍増加しました.
- この関連性は,BMI ≥25の個体においてより強く,活発なレクリエーション活動が少ない個体において潜在的により一般的であった.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

4.8K
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.

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

02:18The Proteasome
9.0K
Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

01:24Serum Studies: Renal Function Tests
43
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.
