炎症可能会改变维生素D.
科学领域:
- 营养流行病学 营养流行病学
- 遗传流行病学遗传流行病学
- 炎症的生物标志物
背景情况:
- 布是一个重要的公共卫生问题.
- 维生素D补充剂正在探索预防跌倒,但高剂量可能会增加跌倒风险.
- 炎症可能会影响维生素D水平和运动功能,影响跌倒风险.
研究的目的:
- 用遗传流行病学方法研究维生素D,炎症和跌倒风险之间的关联.
- 探索炎症如何改变25-氧维生素D[25(OH) D]与跌倒风险之间的关系.
主要方法:
- 利用了来自307,082名参与者的英国生物库数据.
- 进行了观察和门德尔随机化 (MR) 分析.
- 研究了25~OH) D,C反应蛋白 (CRP) 和跌倒风险之间的关联,重点关注炎症患者 (CRP ≥5 mg/L).
主要成果:
- 较高的CRP水平与较高的跌倒几率有关;较高的25(OH) D与较低的跌倒几率有关.
- 在患有炎症 (CRP ≥5 mg/L) 的参与者中观察到25(OH) D和跌倒之间的U形关联,在低度 (<25 nmol/L) 和高度 (≥100 nmol/L) 时风险增加.
- 基因预测较高的25(OH) D显示,在高度炎症 (CRP>20 mg/L) 的个体中,与较高的跌倒风险存在暗示性关联.
结论:
- 炎症似乎改变了维生素D和跌倒风险之间的关系.
- 低和高的25 ((OH) D水平都与慢性炎症患者的跌倒增加有关.
- 这些发现可能解释了在试验中高剂量维生素D补充剂中观察到的跌倒风险增加,需要进一步调查.

Nature and Nurture
20.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Human Genetics
531
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Role of Vitamins in Maintaining Bone Health
3.1K
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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
56
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Cancer Prevention
6.0K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Genome-wide Association Studies-GWAS
12.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
