The complete sequence (14,751 bp) of the mitochondrial DNA (mtDNA) of the opisthobranch gastropod Placida sp. was determined using long PCR and genome-walking techniques. The genome contains 13 protein-coding genes (PCG), 2 ribosomal RNA (rRNA), 22 transfer RNA (tRNA) genes that are typical of metazoan mtDNA, and 2 lengthy noncoding regions with a total length of 1441 bp. All the tRNA genes have general secondary structures without reduced T or D stems. The mitochondrial gene arrangement of Placida sp. is almost identical to that of sea slugs, whereas the tRNA gene arrangement is different from other animals outside Sacoglossa in the Euthyneura. A phylogenetic analysis based on the mitochondrial genome of Euthyneura indicated that Placida sp. and Placida dendritica are closely related to Elysia chlorotica as a sister taxon, which strongly supports their close phylogenetic affinity.

Atherosclerotic cardiovascular and cerebrovascular diseases are the number one killer of human health. In view of the important role of mitochondria in the formation and evolution of atherosclerosis, our manuscript aims to comprehensively elaborate the relationship between mitochondria and the formation and evolution of atherosclerosis from the aspects of mitochondrial dynamics, mitochondria-organelle interaction (communication), mitochondria and cell death, mitochondria and vascular smooth muscle cell phenotypic switch, etc., which is combined with genome, transcriptome and proteome, in order to provide new ideas for the pathogenesis of atherosclerosis and the diagnosis and treatment of related diseases.

Testicular ageing is accompanied by a series of morphological changes, while the features of mitochondrial dysfunction remain largely unknown. Herein, we observed a range of age-related modifications in testicular morphology and spermatogenic cells, and conducted single-cell RNA sequencing on young and old testes in Drosophila. Pseudotime trajectory revealed significant changes in germline subpopulations during ageing.

Background: Acanthocephalans (thorny headed worms) of the genus Pseudoacanthocephalus mainly parasitize amphibians and reptiles across the globe. Some species of the genus Pseudoacanthocephalus also can accidentally infect human and cause human acanthocephaliasis. Current knowledge of the species composition of the genus Pseudoacanthocephalus from amphibians and reptiles in China is incomplete.

Background: The risk of mosquito-borne disease transmission is increasing in temperate climates with the colonization and proliferation of the Asian tiger mosquito vector Aedes albopictus and the rapid mass transport of passengers returning from tropical regions where viruses are endemic. The prevention of major Aedes-borne viruses heavily relies on the use of insecticides for vector control, mainly pyrethroids. In Europe, only deltamethrin is authorized.
