the structure of the sheep cervix limits the application of reproductive biotechnologies such as embryo transfer and artificial insemination. the aim of this study was to determine differences in cervical anatomy and morphology between sanjabi lambs and ewes, and the relationship between cervical anatomy and cervical penetration in ewes. four hundred and sixty eight postmortum cervices belongin...

Binder syndrome is a rare congenital malformation (maxillonasal dysplasia), which was first described in 1939 by Noyes, whereas it was Binder who defined it as a syndrome in 1962. Clinically, there is enlarged nasal angle (arhinoid face), abnormal position of the nasal bones, hypoplastic maxillary, hypoplasia/reduction of the nasal spine, absence/hypoplasia of the frontal nasal sinus (not oblig...

A black tea product was evaluated for anti-mutagenic and in vivo anticancer effects. At concentrations of 1.25 and 2.5 mg/plate, black tea exhibited anti-mutagenicity with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in the Salmonella typhimurium TA100 strain. A Kunming (KM) mouse buccal mucosa cancer model was established by injecting mice with U14 squamous cell carcinoma cells. Following injec...

OBJECTIVE To experimentally develop tracheal stenosis and malacia to test new models of tracheal stents. METHODS We resected three cartilaginous rings from the cervical trachea of dogs in group A (n = 5) and six rings in group B (n = 4) to produce malacia. The mucosa of the region with malacia then received applications of a solution of sodium hydroxide (NaOH) at 23%, and the animals were acc...

BACKGROUND The previously reported prevalence of gastric heterotopia in the cervical esophagus, also termed inlet patch (IP), varies substantially, ranging from 0.18 to 14%. Regarding cases with adenocarcinoma within IP, some experts recommend to routinely obtain biopsies from IP for histopathology. Another concern is the reported relation to Barrett's esophagus. The objectives of the study wer...
