Insidious pericardial journey of an orthodontic metallic retainer wire.

Ingestion of foreign bodies may be a frequent cause of painful dysphagia. We report the case of a metallic wire impacted in the oesophagus with potentially devastating consequences.

The predominant role of IgM in grouper (Epinephelus coioides) mucosal defense against ectoparasitic protozoan infection.

The skin mucosa of fish is exposed to significant challenges from infectious disease agents due to continuous exposure to the aqueous environment. Interestingly, bony fish have evolved to express a unique IgT, which is absent in terrestrials, that appears to play a predominant role in the mucosal-associated lymphoid tissue of the rainbow trout. Nevertheless, in other IgT-producing fish, it is unclear whether IgM or IgT is primarily responsible for protection against infections of cutaneous tissue.

Role of chitin synthases CHS1 and CHS2 in biosynthesis of the cyst wall of Cryptocaryon irritans.

Cryptocaryon irritans, a protozoan parasite that infects marine fish, is characterized by a complex life cycle that includes a cyst-forming reproductive phase. However, the composition of the cyst wall and mechanism of its formation remain unclear. In this study, we identified chitin as a key component of the cyst wall using calcofluor white and wheat germ agglutinin, with Fourier-transform infrared spectroscopy confirming its β-form structure.

Bioinsecticide PA1b alleviates lipopolysaccharide-induced inflammation and impairment of bovine mammary epithelial cells.

Pea Albumin 1, subunit b (PA1b) is a 37 amino acid peptide. It was extracted from pea seeds and showed significant insecticidal activity against certain insects, such as the mosquitoes Culex pipiens and Aedes aegyptii, cereal weevils (genus Sitophilus), and certain species of aphids. Considering that pea seeds are regularly consumed by humans and mammals, PA1b is assumed to be a promising bioinsecticide with no allergenicity or toxicity to hosts.

A Rare Cause of Urinary Incontinence: Vesicouterine Fistula-A Case Report.

Vesicouterine fistula is a rare complication occurring mainly after cesarean sections. We present here a particular case of vesicouterine fistula (VUF) whose only symptom was urinary incontinence. We describe the diagnostic methods used and the surgical treatment used to resolve the case.
