The Indo-Chinese green peafowl Pavo muticus imperator (Galliformes: Phasianidae) is an endangered bird species. However, our present knowledge of the species composition of nematode parasites of this bird remains limited. In the present study, two nematode parasites Heterakis pedioecetes Mawson, 1956 (Ascaridomorpha: Heterakoidea) and Synhimantus (Dispharynx) nasuta (Rudolphi, 1819) (Spiruromorpha: Acuarioidea) were reported from P.

Article Synopsis
  • Research focuses on changes in oral microbial composition related to periodontal disease, comparing healthy individuals to those with severe periodontitis (SP).
  • The study uses 16S ribosomal DNA sequencing to analyze bacterial populations and reveals significant changes in abundance due to the disease and after treatment.
  • Results indicate that nonsurgical periodontal therapy can effectively alter the diversity of oral microbiota, reducing harmful bacteria and enhancing beneficial ones, which could improve treatment outcomes.

The inhibition of the autophagolysosomal pathway mediated by transcription factor EB (TFEB) inactivation in proximal tubular epithelial cells (TECs) is a key mechanism of TEC injury in diabetic kidney disease (DKD). Acetylation is a novel mechanism that regulates TFEB activity. However, there are currently no studies on whether the adjustment of the acetylation level of TFEB can reduce the damage of diabetic TECs.

Previous studies have primarily focused on the influence of temperature and precipitation on phenology. It is unclear if the easily ignored climate factors with drivers of vegetation growth can effect on vegetation phenology. In this research, we conducted an analysis of the start (SOS) and end (EOS) of the growing seasons in the northern region of China above 30°N from 1982 to 2014, focusing on two-season vegetation phenology.

Background: The family Rhabdiasidae (Nematoda: Rhabditida) is a globally distributed group of nematode parasites, with over 110 species parasitic mainly in amphibians and reptiles. However, the systematic position of the family Rhabdiasidae in the order Rhabditida remains unsolved, and the evolutionary relationships among its genera are still unclear. Moreover, the present knowledge of the mitochondrial genomes of rhabdiasids remains limited.

Transcription factor EB (TFEB), known as a major transcriptional regulator of the autophagy-lysosomal pathway, regulates target gene expression by binding to coordinated lysosomal expression and regulation (CLEAR) elements. TFEB are regulated by multiple links, such as transcriptional regulation, post-transcriptional regulation, translational-level regulation, post-translational modification (PTM), and nuclear competitive regulation. Targeted regulation of TFEB has been victoriously used as a treatment strategy in several disease models such as ischemic injury, lysosomal storage disorders (LSDs), cancer, metabolic disorders, neurodegenerative diseases, and inflammation.

Ischemia-reperfusion injury (IRI) is a common cause of acute kidney injury (AKI). The kidney is susceptible to IRI under several clinical conditions, including hypotension, sepsis, and surgical procedures, such as partial nephrectomy and kidney transplantation. Extensive research has been conducted on the mechanism and intervention strategies of renal IRI in past decades; however, the complex pathophysiology of IRI-induced AKI (IRI-AKI) is not fully understood, and there remains a lack of effective treatments for AKI.

Article Synopsis
  • Acanthocephalans of the order Polymorphida are important parasites in birds and mammals, with some species causing zoonotic diseases in humans, particularly acanthocephaliasis.
  • This study reports the complete mitochondrial genomes of two Polymorphidae species for the first time, detailing their gene composition and unique arrangements compared to other acanthocephalans.
  • Phylogenetic analyses reveal new evolutionary relationships among the families of Polymorphida, indicating that Polymorphidae is closely related to Centrorhynchidae and providing valuable genetic data for studying these parasites.

Vegetation makes an outstanding contribution to the stability of ecosystems and to a certain extent reflects the state of the terrestrial ecosystem. Drought conditions greatly affect the growth and development process of vegetation due to its remarkable stochasticity and complexity. Due to the complex coupling mechanism between vegetation and drought, the research on vegetation drought risk is still limited.

Background: The family Toxocaridae is a group of zooparasitic nematodes of veterinary, medical and economic significance. However, the evolutionary relationship of Porrocaecum and Toxocara, both genera currently classified in Toxocaridae, and the monophyly of the Toxocaridae remain under debate. Moreover, the validity of the subgenus Laymanicaecum in the genus Porrocaecum is open to question.

Background: Nematodes of the family Physalopteridae (Spirurida: Physalopteroidea) commonly parasitize the alimentary canal of all major vertebrate groups. However, many physalopterid species are not adequately described, especially regarding the detailed morphology of the cephalic end. The current genetic database for Physaloptera species is still very limited, which seriously hampers molecular-based species identification.
