This review focuses on how research, using chick as a model system, has contributed to our knowledge regarding the development of cranial placodes. This review highlights when and how molecular signaling events regulate early specification of placodal progenitor cells, as well as the development of individual placodes including morphological movements. In addition, we briefly describe various t...
Ancient DNA (aDNA) research involves invasive and destructive sampling procedures that are often incompatible with anthropological, anatomical, and bioarcheological analyses requiring intact skeletal remains. The osseous labyrinth inside the petrous bone has been shown to yield higher amounts of endogenous DNA than any other skeletal element; however, accessing this labyrinth in cases of a comp...
Linear and depressed skull fractures are frequent mechanisms of head injury and are often associated with traumatic brain injury. Accurate knowledge and understanding of the fracture of cranial bone can provide insight into the prevention of skull fracture injuries and associated lesions of soft neural tissue and help aid the design of energy absorbing head protection systems. Cranial bone is a...
PURPOSE Dental crowding occurring in the anterior part of the mandible in the early mixed dentition has been a subject of increasing concern for child patients, their parents, and the pediatric dentist. The aim of this study was to evaluate indicators of crowding found at the primary dentition, which may lead to the future manifestation of crowding at the anterior part of the mandibular arch in...
Using morphological, histological, and TEM analyses of the cranium, we provide a detailed description of bone and suture growth in zebrafish. Based on expression patterns and localization, we identified osteoblasts at different degrees of maturation. Our data confirm that, unlike in humans, zebrafish cranial sutures maintain lifelong patency to sustain skull growth. The cranial vault develops i...
—Phylogenetic relationships both within and between the scincomorph families Gerrhosauridae and Cordylidae are in need of re-examination. Currently the basal gerrhosaurid is unknown, although Angolosaurus skoogi previously was proposed as the sister taxon to mainland African gerrhosaurids. Many details of the cranial osteology of A. skoogi are also unknown because of the rarity in museum collec...
background rodents play a major role in economic losses and public health problems. these animals are considered as natural reservoir hosts of zoonotic cutaneous leishmaniasis (zcl), one of the major health concerns in iran. conclusions the spatial and temporal monitoring of wild rodents will help to predict the potential zoonotic rodent-borne diseases. objectives this research was aimed to stu...
