On a method of determination of chlorophyll in cells of algae collected on a membrane filter. [Translation from: Trudy Instituta Biologii Vnutrennykh Vodnany 11(14), 198-202, 1966.] [PDF]
, 1966 The original method, proposed by Yentsch (1957), of determination of chlorophyll directly in the cells, attracts attention by its simplicity. In order to measure the content of chlorophyll by this method, a determined volume of suspension of algae is ...

Influence of dietary carrot and paprika on egg physical characteristics and yolk color [PDF]
Food and Feed Research, 2018 For many consumers egg yolk color is a very important characteristic of egg quality. Since hens are not able to synthesize coloring pigments, the intensity of the yolk color depends directly on the content and profile of pigmenting carotenoids present in

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota
Advanced Science, EarlyView.This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Advanced Science, EarlyView.This study elucidates the mechanism by which heat stress regulates skin pigmentation: heat stress upregulates CX3CL1 through the MYC‐WDR5‐H3K4me3 axis, thereby activating the CX3CL1/CX3CR1‐JNK signaling pathway and ultimately promoting melanogenesis. These findings provide novel potential therapeutic targets for pigmentary skin disorders.
