The karyotypes of three additional species of Edentata are described. The differences in karyotype between Tolypeutes matacus (2n = 38), and other species of armadillo is remarkable. Three species of Euphractini were compared through G- and C-banding patterns. Chaetophractus villosus appears to be much closer to Zaedyus pichiy than suggested by taxonomy. On(More)
An accidental mating between a male eland and a female kudu produced an animal with primarily eland phenotypic characteristics. Despite pronounced male behaviour the animal was azoospermic. Histological examination of the testis showed complete lack of germ cells. Chromosome studies with analysis of Giemsa bands showed that the parental karyotypes differed(More)
PURPOSE The aim of this study was to verify possible associations between oral health-related quality of life (QoL) and the position of the lower third molar among patients undergoing lower third molar surgery during the first postoperative week. MATERIALS AND METHODS We performed an interventional prospective study of 86 patients for whom the(More)
The purpose of this study was to determine some ultrasonographic standards of temporomandibular joints with normally positioned discs. Nineteen patients from 18 to 45 years old (average age: 27.4 years; 16 females and 3 males), with history of orofacial pain, but without clinical or radiological signs of disc displacement, underwent ultrasonography (US) and(More)
Collagenous fibroma is an uncommon benign soft tissue lesion that has a wide anatomic distribution. We describe a case of a collagenous fibroma that appeared in the left soft and hard palate of a 37-year-old woman as a 5.0-cm solitary, firm nodule. Microscopically, it was composed of stellate or spindle-shaped cells embedded in hypovascular fibrous stroma.(More)
Our long-term objective is to devise reliable methods to generate biological replacement teeth exhibiting the physical properties and functions of naturally formed human teeth. Previously, we demonstrated the successful use of tissue engineering approaches to generate small, bioengineered tooth crowns from harvested pig and rat postnatal dental stem cells(More)
There is no conclusive evidence from clinical trial studies regarding preemptive analgesic interventions. Clinical trials are necessary to evaluate the efficacy of preemptive analgesic interventions already demonstrated in animal studies. Thus, it is necessary to evaluate the analgesic effect of preoperative administration of ibuprofen alone or(More)
Synaptonemal complexes were analysed by electron microscopy in 2 bucks heterozygous for the 5/15 Robertsonian translocation. The cis configuration (free homo-logous 5 and 15 chromosomes on the same side of the 5/15 translocated chromosome) was found in all 50 cells examined. This feature is considered a prerequisite for the development of balanced gametes.(More)
