Complete mitochondrial genomes of Dactylogyrus crucifer and Dactylogyrus zandti reveal distinct patterns of codon usage within Dactylogyrus.

Monogeneans of the genus Dactylogyrus Diesing, 1850, the largest genus in the family Dactylogyridae, mostly parasitize the gills of cyprinoid hosts; however, only 3 Dactylogyrus' mitochondrial genomes (mitogenomes) are studied so far. The aim of this research is to extend our understanding of the mitogenomes of Dactylogyrus. We sequenced the mitogenomes of D.

Identification of a new species of von Nordmann, 1832 (Monogenoidea Gyrodactylidae) isolated from in Yarkand River, Xinjiang, China.

To investigate infection of fish in the river system of Xinjiang (China), individuals were isolated from specimens of . Morphological characterization and phylogenetic analysis based on rDNA locus revealed that the gyrodactylids belong to new species. n.

Synthesis of environmental-friendly ion-imprinted magnetic nanocomposite bentonite for selective recovery of aqueous Sc(III).

A novel reusable ion imprinted nanocomposite magnetic bentonite(IIPNMB) was prepared for selective recovery of aqueous scandium. Based on the fact that oxyphosphorus functional groups in sodium tripolyphosphate have good affinity to Sc(III) and chitosan is rich in hydroxy and amino active sites, they were chosen to build ion imprinted layers. Mesoporous IIPNMB showed good adsorption performance.

Intergenerational Religious Participation in Adolescence and Provision of Assistance to Older Mothers.

Objective: This investigation examined the association between intergenerational religious activities in adolescence and provision of assistance to older mothers up to 45 years later.

Background: Guided by perspectives of the life course and intergenerational solidarity, this research tested whether children's early religious participation with mothers predicted the amount of assistance children later provided, whether mothers' disability and widowhood served as moderators of this relationship, and whether any such moderation was mediated by emotional closeness, geographic proximity, and eldercare norms.

Method: Data derived from 220 adolescents who participated in the Longitudinal Study of Generations in 1971, and up to four follow-up surveys between 1997 and 2016, yielding 608 person-year observations.

Analysis of Chromosomal Numbers, Mitochondrial Genome, and Full-Length Transcriptome of Onychostoma brevibarba.

Onychostoma brevibarba is a new discovered species which is distributed in Xiang Jiang River of the middle Chang Jiang basin in Hunan Province, South China. In this study, the ploidy levels of O. brevibarba were confirmed by counting chromosomal numbers and analyzing karyotype.
