- 为了比较RVEG的安全性,与红色E120 (来自动物) 和合成E124.4进行比较.
- 评估RVEG对毒性终点,基因表达和肌肉超结构的影响.
主要方法:
- 在护盾阶段的斑马鱼胚胎被暴露在RVEG,E120和E124中72小时.
- 使用了一种多学科的方法,包括评估生存率,化率,心率和基因毒性.
- 进行了行为分析和肌肉超结构和基因表达的检查 (gfap,chchd2,notch1a).
主要成果:
- RVEG和E120没有显著影响化率,心率或运动性.
- 暴露于RVEG导致骨肌组织的中度变化.
- RVEG显著改变了gfap,chchd2和notch1a基因的表达,而E124和E120显示出不同的毒性概况.
结论:
- 根据标准毒性参数,RVEG似乎比合成E124和动物衍生的E120毒性更低.
- 然而,RVEG诱导的基因表达和肌肉解剖学的变化需要进一步调查其长期安全性.
- 该研究强调,需要对天然食品染料进行超越传统毒性终点的全面安全评估.

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

01:21Redox Titration: Overview
3.5K
Redox titration is a chemical analysis technique used to determine the concentration of an unknown substance by measuring the electron transfer in a redox (reduction-oxidation) reaction. The process involves gradually adding a titrant with a known concentration of an oxidizing or reducing agent, to the analyte, the solution with an unknown concentration, until reaching the endpoint, which indicates the completion of the reaction between the two substances. Ensuring the analyte is in a single...

2.8K
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...
