概括
放射性膝关节关节炎 (OA) 在大约三分之一的40岁以上的越南成年人中普遍存在. 虽然OA患者的区域骨矿物质密度 (aBMD) 较高,但他们的小腿皮层体积骨密度 (vBMD) 显著较低.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 骨的新陈代谢 骨的新陈代谢
背景情况:
- 放射性膝关节骨关节炎 (OA) 是常见的,但其与骨密度的关联需要进一步澄清.
- 以前的研究表明,OA患者的骨矿物质密度 (aBMD) 较高,但骨折风险与非OA患者相似.
- 了解OA和体积骨密度 (vBMD) 之间的关系对于评估骨健康至关重要.
研究的目的:

- 用凯尔格伦和劳伦斯等级 (等级≥2) 评估膝关节OA.
- 区域骨矿物质密度 (aBMD) 通过DXA测量部部和腰椎;部vBMD使用pQCT测量.
主要成果:
- 放射性膝关节OA的患病率约为31%,随年龄增长而增加.
- 膝关节OA患者与非OA患者相比,表现出更高的股骨部aBMD (ES = 0.04,95%CI:0.02-0.05).
- 在膝关节骨质炎患者中,皮皮层的vBMD显著降低 (ES = -8.15,95% CI:-14.52至-1.8).

Essential Minerals for Bone Health
6.1K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Water and Mineral Acquisition
35.4K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Minerals
1.1K
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Knee Joint
3.1K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Association Areas of the Cortex
9.0K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Associative Learning
1.3K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
