| [crystallization of reptile hemoglobin during its digestion in a pentastomide]. | the hemoglobin of the lizard tarentola annularis has been studied within erythrocytes being digested in the gut of a parasitic pentastomide, raillietiella sp. the hemoglobin is crystallized in the form of bundles comprised of numerous tubules (up to 2000). these tubules are simple or complex. simple tubules are 50 nm in diameter; their wall is made up of two electron-opaque rings, separated by a clear ring. complex tubules are up to 100 nm in diameter and show as many as 13 concentric walls. hig ... | 1985 | 3831386 |
| glyceraldehyde 3-phosphate dehydrogenase is an enzyme-crystallin in diurnal geckos of the genus phelsuma. | lenses from diurnal geckos, phelsuma barbouri, phelsuma madagascariensis grandis and phelsuma serraticauda contain a prominent 37 kda polypeptide (pi-crystallin) that is not present in lenses from the nocturnal geckos, gekko gekko, hemidactylus garnoti, tarentola annularis, and uroplatus henkeli. this protein was partially purified from p. serraticauda and was identified as glyceraldehyde 3-phosphate dehydrogenase (gapd). the gapds, which constitute 14-24% of the lens soluble protein in the diur ... | 1995 | 7733971 |
| expression of human tissue plasminogen activator in the trypanosomatid protozoan leishmania tarentolae. | a variety of recombinant protein expression systems have been developed for heterologous genes in both prokaryotic and eukaryotic systems such as bacteria, yeast, mammals, insects, transgenic animals and transgenic plants. also, it has been reported that leishmania tarentolae, a trypanosomatid protozoan parasite of the white-spotted wall gecko (tarentola annularis), has the capability of expressing heterologous genes. trypanosomatidae are rich in glycoproteins, which can account for more than 10 ... | 2007 | 17371294 |
| recombinant protein expression in leishmania tarentolae. | a variety of recombinant protein expression systems have been developed for heterologous genes in both prokaryotic and eukaryotic systems such as bacteria, yeast, mammals, insects, transgenic animals, and plants. recently leishmania tarentolae, a trypanosomatid protozoan parasite of the white-spotted wall gecko (tarentola annularis), has been suggested as candidate for heterologous genes expression. trypanosomatidae are rich in glycoproteins, which can account for more than 10% of total protein; ... | 2009 | 19779853 |
| fine structure of the dorsal lingual epithelium in tarentola annularis and crocodylus niloticus. | the present study examined the morphological features, histological and histochemical aspect of the tongue of two reptilian species, tarentola annularis (family: gekkonidae) and crocodylus niloticus (family: crocodylidea), with different habitats, feeding patterns and behaviours, by light and scanning electron microscope. it was observed, that the bifurcation of the tongue was more visible in tarentola annularis. conical and filamentous papillae were observed on the lingual body of tarentola ann ... | 2016 | 26503178 |
| 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 |
| armored geckos: a histological investigation of osteoderm development in tarentola (phyllodactylidae) and gekko (gekkonidae) with comments on their regeneration and inferred function. | osteoderms are bone-rich organs found in the dermis of many scleroglossan lizards sensu lato, but are only known for two genera of gekkotans (geckos): tarentola and gekko. here, we investigate their sequence of appearance, mode of development, structural diversity and ability to regenerate following tail loss. osteoderms were present in all species of tarentola sampled (tarentola annularis, t. mauritanica, t. americana, t. crombei, t. chazaliae) as well as gekko gecko, but not g. smithii. gekkot ... | 2015 | 26248595 |
| ecology of some sympatric reptilian species from egypt with special reference to helminthic parasites: ptyodactylus guttatus and tarentola annularis. | ptyodactylus guttatus and tarentola annularis are sympatric throughout most of their geographical distribution in egypt. their temporal activities, feeding habits, food items, feeding strategy are almost similar. these species have been harboured 6 species of nematodes, one species of trematodes in addition to helminthic cysts of cestodes in the liver of each specific host. | 1995 | 7665935 |
| developmental stages of the climbing gecko tarentola annularis with special reference to the claws, pad lamellae, and subdigital setae. | studying the in ovo mode of development of squamates has the advantage of allowing easy access to embryos without surgically compromising gravid females. despite the non-ophidian squamates being a very diverse lineage of reptiles, embryonic tables for individuals of this group are very few. here, i present the first in ovo embryonic table for a basal multi-scansored, pad-bearing gecko, tarentola annularis. in this gecko, only the iii and iv digits bear claws. eleven embryonic stages are describe ... | 2015 | 26055807 |
| a description of haemogregarina species naturally infecting white-spotted gecko (tarentola annularis) in qena, egypt. | the present study describes the developmental stages of haemogregarina species in the blood and tissues of naturally infecting white-spotted gecko tarentola annularis collected from qena, egypt. different parasite's forms were observed infecting the erythrocytes. the gamonts enclosed within parasitophorous vacuole and seems to have no clear effect on the host cell especially in case of immature parasite forms. but in the presence of mature gamonts the host cell nucleus displaced. the parasitaemi ... | 2014 | 25597149 |
| cell-mediated immunity in the gecko, tarentola annularis. | the gecko tarentola annularis, rejects skin allografts in a chronic manner, whereas the cutaneous response to tuberculin has the characteristics of mammalian delayed hypersensitivity reaction. moreover, inoculation of gecko's spleen lymphocytes into skin of intact or whole-body--heavily irradiated allogeneic hosts, readily elicits a severe, local reaction (normal lymphocyte transfer reaction). the data indicate that slow skin graft rejection in t. annularis cannot be ascribed to either defective ... | 1981 | 7009229 |
| ontogeny of the moorish gecko tarentola mauritanica with emphasis on morphogenesis of the skin and its derivatives. | studying reptilian embryonic development provides answers to many questions related to the development of tetrapods. reptilian skin has been recently considered in studies at the evo-devo level. the lizard epidermis has to be shed periodically. at the embryonic level, contention exists regarding the first layers to appear, whether the oberhautchen or the clear layer, and whether the shedding complex develops before hatching. geckos exhibit diverse morphologies independently evolved multiple time ... | 2020 | 32410344 |
| embryonic skull development in the gecko, tarentola annularis (squamata: gekkota: phyllodactylidae). | tarentola annularis is a climbing gecko with a wide distribution in africa north of the equator. in the present paper, we describe the development of the osteocranium of this lizard, from the first appearance of the cranial elements up to the point of hatching. this is based on a combination of histology and cleared and stained specimens. this is the first comprehensive account of gekkotan pre-hatching skull development based on a comprehensive series of embryos, rather than a few selected stage ... | 2020 | 32485010 |
