概括
维生素D代谢物比率 (VMR) 是对甲状腺激素 (PTH) 水平的更好的指标,而不是传统的标记物,特别是在老年人中. 这表明VMR可能是维生素D状态的有用标志物.
科学领域:
- 内分泌学 在内分泌学.
- 代谢过程中的代谢.
- 营养科学 营养科学
背景情况:
- 评估维生素D的充足程度通常依赖于抑制副甲状腺激素 (PTH) 分泌,通常使用25-基维生素D [25(OH) D].
- 文献显示25-OH-D的切割值存在很大差异,这促使对其他维生素D代谢物进行研究.
- 非经典代谢物如24,25-二氧维生素D [24,25(OH) 2D3]及其在反映维生素D状态中的作用正在积极研究中.
研究的目的:
- 调查PTH,年龄和维生素D状态标志物之间的关系.
- 为了比较经典 (25(OH) D3) 和非经典 (24,25(OH) 2D3,VMR) 标记在反映维生素D状态方面的有效性.
- 确定VMR是否比25(OH) D3和24,25(OH) 2D3更可靠的维生素D状态指标,特别是关于与年龄相关的变化.
主要方法:
- 一项前性队列研究,涉及162名健康的高加索成年人.
- 对与年龄和维生素D代谢物的PTH水平的分析:25(OH) D3,24,25(OH) 2D3,以及维生素D代谢物比率 (VMR).
- 统计分析以评估相关性并确定VMR在预测PTH-年龄关系中的最佳值.
主要成果:
- 在不同的VMR,25(OH) D3和24,25(OH) 2D3值中观察到PTH和年龄之间的显著关系.
- 与25(OH) D3和24,25(OH) 2D3.3相比,VMR对PTH年龄相关性表现出更强的控制.
- 确定了11.7的最佳VMR值,在这个值以上和以下的PTH年龄相关性显著不同.
结论:
- PTH和维生素D状态之间的关系取决于年龄,老年人对PTH升高的敏感性增加.
- 维生素D的耐药性,而不是缺乏,可能会导致老年人PTH水平更高.
- 维生素D代谢物比率 (VMR) 显示出作为评估维生素D状态的潜在标记物具有前景,需要在更大的研究中进一步调查.

2.6K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:23Role of Skin in Vitamin D Synthesis
5.1K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

01:25Role of Vitamins in Maintaining Bone Health
3.2K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:21Skeleton and Calcium Homeostasis
4.4K
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.

00:59The Parathyroid Glands
1.9K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

01:29Bone Disorders
3.4K
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...
