Noninbred female white rats were fed for 30 days with diets containing 137Cs and 85Sr in indicative doses. After that the animals received some sea products to investigate their radioprotective properties. Natural sea products proved able to influence the kinetics of the radionuclides metabolism. Laminaria salad "Dalnevostochny" given in the dose 20 g per animal reduced the accumulation of radioactive Cs and Sr by 76.7 and 57.6%, respectively. Moreover, sea products stabilize functional activity of peripheral blood natural killers which are important in immunological defense of the body.

Catalytic subunit of DNA polymerase ζ (REV3), involved in translesion-replication is evolutionarily conserved from yeast and plants to higher eukaryotes. However, a large intermediate domain is inserted in REV3 of humans and mice. The domain has "DUF4683" region, which is significantly similar to human neurite extension and migration factor (NEXMIF).

Marine red alga Laurencia composita was collected from seven sampling locations in Japan, and all samples were identified based on morphological studies as well as rbcL sequencing analysis. This is the first report of the isolation of (-)-8-bromo-9-hydroxy-(E)-γ-bisabolene (1) as a natural product, and bisabolene-type and β-chamigrene-type sesquiterpenes found in L. composita collected in Japan.

Mycosporine-like amino acids are water-soluble secondary metabolites that protect photosynthetic microorganisms from ultraviolet radiation. Here, we present direct evidence for the production of these compounds in surface scums of cyanobacteria along the Baltic Sea coast. We collected 59 environmental samples from the southern coast of Finland during the summers of 2021 and 2022 and analysed them using high-resolution liquid chromatography-mass spectrometry.

Photosynthetic eukaryotic microalgae are key primary producers in the Antarctic sea ice environment. Anticipated changes in sea ice thickness and snow load due to climate change may cause substantial shifts in available light to these ice-associated organisms. This study used a laboratory-based experiment to investigate how light levels, simulating different sea ice and snow thicknesses, affect fatty acid (FA) composition in two ice associated microalgae species, the pennate diatom Nitzschia cf.

A kind of sulfur-doped carbon dots was prepared which were encapsulated with polydopamine (S-CDs@PDA) that has fluorescence response on polyethylene (PE) microplastics (MPs). Modified membranes were constructed using S-CDs@PDA for MP detection. Through heating and vacuum filtration process, yellow emission from the modified membrane appeared because of the combination between S-CDs@PDA and PE MPs.
