| an osteological and histological investigation of cranial joints in geckos. | cranial kinesis is a widespread feature of gekkotan lizards. previous studies of kinesis in lizards often described the relevant, mobile joints as synovial, thus characterized by the presence of a synovial cavity lined with articular cartilage. to date however, detailed investigations of cranial joint histology are lacking. we examined eight cranial joints (quadrate-articular, quadrate-pterygoid, quadrate-otooccipital, quadrate-squamosal, epipterygoid-prootic, epipterygoid-pterygoid, basisphenoi ... | 2011 | 21254447 |
| differentiation of sex chromosomes and karyotypic evolution in the eye-lid geckos (squamata: gekkota: eublepharidae), a group with different modes of sex determination. | the eyelid geckos (family eublepharidae) include both species with temperature-dependent sex determination and species where genotypic sex determination (gsd) was suggested based on the observation of equal sex ratios at several incubation temperatures. in this study, we present data on karyotypes and chromosomal characteristics in 12 species (aeluroscalabotes felinus, coleonyx brevis, coleonyx elegans, coleonyx variegatus, eublepharis angramainyu, eublepharis macularius, goniurosaurus araneus, ... | 2010 | 20811940 |
| systemic mastocytosis in an african fat-tail gecko (hemitheconyx caudicinctus). | a 3-year-old african fat-tail gecko (hemitheconyx caudicinctus) suddenly became lethargic and died 2 days later. necropsy examination revealed a submandibular mass and discolouration of the liver, kidneys and skeletal muscles of the tail. microscopical evaluation revealed neoplastic mast cells in the skin, liver, kidneys, skeletal muscles, bones, spleen, uterus, ovaries and lungs. exfoliative cytological, histopathological and ultrastructural features were consistent with systemic mastocytosis. ... | 2014 | 24813156 |
| mitochondrial genomes of two african geckos of genus hemitheconyx (squamata: eublepharidae). | mitochondrial genomes of two eyelid geckos (hemitheconyx caudicinctus and hemitheconyx taylori) were sequenced. although these genomes conserve a typical vertebrate gene organization, trna(gln) gene of the former appears to have been pseudogenized. a very extensive rna editing may restore its function in the rna level or a functional trna(gln) encoded in the nuclear chromosome may be imported into mitochondria. | 2012 | 22708855 |
