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.

New species of von Nordmann, 1832 (Monogenoidea: Gyrodactylidae) from (Kessler, 1874) (Schizothoracinae) in the Kunes River (Yili River basin), China.

Yili River system hosts a diverse fauna of fishes and parasites. is a rare and endangered aboriginal cold-water fish inhabit in the Yili river system. Our research identified a new species n.

Mitochondrial phylogenomics provides conclusive evidence that the family Ancyrocephalidae is deeply paraphyletic.

Background: Unresolved taxonomic classification and paraphyly pervade the flatworm class Monogenea: the class itself may be paraphyletic and split into Polyopisthocotylea and Monopisthocotylea; there are some indications that the monopisthocotylean order Dactylogyridea may also be paraphyletic; single-gene markers and some morphological traits indicate that the family Ancyrocephalidae is paraphyletic and intertwined with the family Dactylogyridae.

Methods: To attempt to study the relationships of Ancyrocephalidae and Monopisthocotylea using a phylogenetic marker with high resolution, we sequenced mitochondrial genomes of two fish ectoparasites from the family Dactylogyridae: Dactylogyrus simplex and Dactylogyrus tuba. We conducted phylogenetic analyses using three datasets and three methods.

The complete mitochondrial genomes of Paradiplozoon yarkandense and Paradiplozoon homoion confirm that Diplozoidae evolve at an elevated rate.

Background: Diplozoidae are monogenean (Monogenea: Polyopisthocotylea) fish parasites characterised by a unique life history: two larvae permanently fuse into an X-shaped "Siamese" organism. Taxonomy and phylogeny of Diplozoidae and Polyopisthocotylea remain unresolved due to the unavailability of molecular markers with sufficiently high resolution. Mitogenomes may be a suitable candidate, but there are currently only 12 available for the Polyopisthocotylea (three for Diplozoidae).

A New Species of Paradiplozoon (Monogenea: Diplozoidae), A Gill Parasite of the Schizothorax Fish (Cyprinidae: Schizothoracinae) from the Yarkand River, Xinjiang, China.

Introduction: Monogeneans of the genus Paradiplozoon were found on the gills of specimens of five species of schizothoracid caught using fyke nets in the upper stream of the Yarkand River, Xinjiang, China in May-August 2019.

Methods: The preserved parasite were stained with boric acid magenta and hematoxylin, respectively. Morphological observations, line drawings, photomicrographs and measurements were made in Nikon ECLIPSE E200 imaging optical microscope and digitally edited.

[Association of single nucleotide polymorphism of megsin gene with IgA nephropathy].

Objective: To investigate whether the single nucleotide polymorphisms (SNPs) in the gene of megsin, a novel serine protease inhibitor, account for the pathogenicity of IgA nephropathy (IgAN).

Methods: A comprehensive megsin gene survey, including the entire coding region, part of the regulatory region, and exon-intron connection region, was performed by PCR-direct sequencing on the DNA samples of peripheral blood from 12 randomly selected IgAN patients and 12 randomly selected healthy persons. Eight SNPs with moderate or high frequencies (with the frequency > 5%) selected from the 11 SNPs found were used as candidate SNPs.

[The analysis of the factors for postoperative blood pressure recovery of aldosterone producing adenoma patients].

Objective: To investigate the factors regarding the recovery of postoperative blood pressure of aldosterone producing adenoma (APA) patients.

Methods: Sixty-eight patients with APA were recruited and their data including retinal blood vessel by Doppler sonography, urinary trace albumin, pathological changes of renal biopsy and the adrenal tissues around the adenoma were analyzed in order to determine the correlation between these data and postoperative durative hypertension.

Results: Postoperative durative hypertension occurred in 14 cases (41.
