Bioinformatics and genomic mining may shed light on evolutionary relationships among them. Therefore, the aim of this study was to assess the biodiversity and especially the strategies evolved within the Idiomarina genus, with the primary focus on the taxonomy and genomic adaptations of two novel strains affiliated with Idiomarina genus isolated from unique environment - brines of two Early Miocene salt deposits.

Chromosomal mapping of 5S rDNA in two species of the genus Acanthocephalus (Echinorhynchida).

Chromosomal mapping of 5S rDNA in two Acanthocephala species was performed for the first time using fluorescence in situ hybridization (FISH) with a 5S rDNA probe. The 5S rDNA PCR products from the genomes of both species were sequenced and aligned and an identical 141 bp long coding region was determined. The same patterns of 5S rDNA gene cluster distribution were observed, with FISH signal restricted to a single autosomal chromosome pair.

Female Phalangium opilio use fellatio to compensate sexual avoidance.

Sexual conflict arises from differences in reproductive interests between the sexes. We allowed the female harvestman Phalangium opilio to sequentially mate with two different males to examine female sexual receptivity in this species. Virgin females were more sexually receptive than non-virgins.

Altered sex differences related to food intake, hedonic preference, and FosB/deltaFosB expression within central neural circuit involved in homeostatic and hedonic food intake regulation in Shank3B mouse model of autism spectrum disorder.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder accompanied by narrow interests, difficulties in communication and social interaction, and repetitive behavior. In addition, ASD is frequently associated with eating and feeding problems. Although the symptoms of ASD are more likely to be observed in boys, the prevalence of eating disorders is more common in females.

Selective Precipitation of REE-Rich Aluminum Phosphate with Low Lithium Losses from Lithium Enriched Slag Leachate.
