概括
这项研究发现,虽然孩子们.
科学领域:
- 营养科学 营养科学
- 眼科医生 眼科 眼科
- 皮肤病学 皮肤病学
背景情况:
- 胡卜素,植物颜料具有抗氧化和光过特性,积聚在人体组织,如视网膜和皮肤.
- 关于儿童的胡卜素状况的研究有限,特别是影响黄斑和皮肤胡卜素水平的因素.
- 这项研究通过检查儿童的年龄,性别,种族,体重状况和饮食摄入量与胡卜素沉积的关系来解决这一差距.
研究的目的:
- 研究各种人口和饮食因素与儿童斑点和皮肤中的胡卜素水平之间的关系.
- 为了将儿童的斑点色素光学密度 (MPOD) 和皮肤胡卜素评分与现有的成人数据进行比较.
- 为了确定体重状况是否影响儿科患者的胡卜素沉积.
主要方法:
- 斑点色素光学密度 (MPOD) 用异色彩闪光学测量在375名儿童 (7-13岁) 中.
- 在一个亚样本 (N=181) 中通过反射光谱评估皮肤类胡卜素,并使用区块食物频率问卷 (N=101) 评估饮食类胡卜素摄入量.
- 统计分析包括部分相关性和逐步线性回归,控制年龄,性别,种族和BMI百分位数.
主要成果:
- 平均MPOD为0.56±0.22,平均皮肤胡卜素评分为282±94.6.6.
- 在MPOD和皮肤胡卜素之间没有发现显著的相关性 (r = 0.02,P = 0.76).
- 更高的BMI百分位与皮肤胡卜素 (stdβ = -0.42,P < 0.001) 有负相关性,但不是MPOD (stdβ = -0.04,P = 0.70). MPOD和皮肤胡卜素与各自的饮食摄入量有积极的关联 (MPOD的卢tein + Zeaxanthin,皮肤的一般胡卜素).
结论:
- 儿童的MPOD值高于成年人群中报告的值.
- 斑点和皮肤胡卜素,虽然没有直接相关,但与相关的饮食摄入量有关.
- 儿童的皮肤胡卜素水平可能会因体重增加而受到负面影响.

2.5K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

2.0K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

6.1K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
