Potential radiosensitive germline biomarkers in the testes of wild mice after the Fukushima accident.

We investigated potential germline-specific radiosensitive biomarkers in the testes of large Japanese field mice (Apodemus speciosus) exposed to low-dose-rate (LDR) radiation after the Fukushima accident. Fukushima wild mice testes were analysed via RNA-sequencing to identify genes differentially expressed in the breeding and non-breeding seasons when compared to controls. Results revealed significant changes during the breeding season, with Lsp1 showing a considerable upregulation, while Ptprk and Tspear exhibited significant reductions.

sp. nov., isolated from Vestrebroggerbreen, a valley glacier in Svalbard, Arctic.

A Gram-stain-negative, rod-shaped bacterial strain designated as 20VBR1 was isolated from a valley glacier (Vestrebroggerbreen) snout ice sample from Ny-Ålesund, Svalbard, Arctic. The colonies were smooth, circular and light creamish on half-strength R2A agar and grew at 10-35 °C (optimum, 20 °C), at pH 6.5-8.

Biodegradation of petroleum based and bio-based plastics: approaches to increase the rate of biodegradation.

Plastic production and consumption are on the rise due to their variety of uses. Plastics often accumulate in the environment and pose a risk due to the lack of a viable strategy for their safe disposal. Even prohibiting plastic covers does not solve the problems of plastic waste generation.

Impact of anthropogenic organic matter on bacterial community distribution in the continental shelf sediments of southeastern Arabian Sea.

The objective of this study was to understand the influence of anthropogenic organic matter on the spatial distribution microbial community in the continental shelf sediments of the Southeastern Arabian Sea (SEAS). The sediment samples were taken from the inner shelf (30 m depths) and outer shelf (100-200 m). The C:N ratio of the sediment displayed a significant variation between the inner and outer shelf and a higher terrestrial organic input in the inner shelf.

Seasonal variation of the prevalence of cymothoid isopod (Crustacea, Isopoda), parasitizing on the host fish collected from the Southwest coast of India.

Parasitological investigations on the occurrence of isopod parasites in fishes collected from off Cochin coast along Southwest India was carried out for a period of 1 year from January 2018 to December 2018. Altogether 20 species of fishes were analysed from 12 families including Scombridae, Carangidae, Clupeidae, Nemipteridae, Hemiramphidae, Belonidae, Menidae, Priacanthidae, Sphyraenidae, Stromateidae, Coryphaenidae. Infestation of was noticed only in the host fish Totally 619 specimens of were examined for the presence of isopod parasite, .
