AI Article Synopsis

  • Major climate changes and animal movement may lead to the spread of parasites and their vectors, affecting population persistence.
  • Parasites can adapt to new hosts and environments, impacting the growth of these hosts, with one example being the air sac nematode in great tits in Slovakia.
  • In a study in southern Germany, researchers found the nematode infecting four new bird species and recommend further research due to the potential risks to their populations.

Article Abstract

Major climatic changes in conjunction with animal movement may be associated with the spread of parasites and their vectors into new populations, with potentially important consequences for population persistence. Parasites can evolve to adapt to unsuitable ecological conditions and take up refuge within new host species, with consequences for the population growth of the new host species. One parasite species that has likely been increasing its geographic range, and potentially infecting new hosts, is the recently described air sac nematode , in great tits () in Slovakia. In this study, we screened wild birds for potential air sac nematode infection in a woodland area of southern Germany. We identified four additional host species: Eurasian nuthatch, great spotted woodpecker, greenfinch and robin. As infection by this group of nematodes can be highly pathogenic, we recommend further investigation into its potential risk to these populations.

Background And Objective: This study aimed to determine the effects of in ovo formula product injection on hatching parameters, chick quality, small intestinal development and ileum histology of breeder hen eggs.

Methods: A total of 400 fertilised eggs were obtained from the Atak-S parent flock at 42 weeks of age for the experiment. The experiment was designed in two groups: a control group (C), in which no injection was performed, and the other group in which a solution containing formula products at concentrations of 1.

Introduction: (MG) infection is a primary cause of chronic respiratory disease in poultry, threatening the economic viability of China's goose-farming industry. This study investigated the pathogenicity and drug resistance of an MG strain isolated from geese and whole-genome sequenced the strain.

Material And Methods: A strain designated MG-GD01/22 was isolated from the air-sac tissues of five geese with chronic respiratory disease on a Guangdong goose farm.

Study on the Abrasive Blasting Mechanism of Solder Welded 304V Wire in Vascular Intervention.

Micromachines (Basel)

November 2024

Department of Vascular Surgery, General Surgery Clinical Center, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, 100 Haining Road, Shanghai 200080, China.

The solder burrs on the 304V wire surface can easily scratch the vascular tissue during interventional treatment, resulting in complications such as medial tears, bleeding, dissection, and rupture. Abrasive blasting is often used to remove solder burr and obtain a smooth surface for the interventional device. This study conducted an abrasive blasting experiment to explore the effects of process parameters (air pressure, lift-off height, abrasive volume, and abrasive type) on processing time, surface roughness, and mechanical properties to reveal the material removal mechanism.

The adsorption and aggregation of amphiphiles at different solvent interfaces are of great scientific and technological importance. In this study, interfacial tension measurements of surface-active compounds-ionic liquid 2-dodecyl-2,2dimethylethanolammonium bromide (12Cho.Br) and cationic surfactant cetyltrimethylammonium bromide (CTAB)-were conducted both in the absence and presence of ciprofloxacin (CIP).
