Hox genes play a major role in the morphological diversification of the anteroposterior body axis of animal embryos by switching the fates of segments between alternative developmental pathways [1]. In their role of controlling segment diversity, Hox proteins are responsible for many different morphological structures and cell types within a given segment. But it is still largely a mystery how ...

Urophora merzisp. n. reared from flower heads of Centaurea behen Linnaeus is described from Iran. It is similar to Urophora campestris, Urophora sachalinensis, Urophora stylata, Urophora tsoii and Urophora vera in wing pattern with 3 well developed crossbands and indistinct subbasal crossband, differing in aculeus tip with two pairs of diminished preapical steps and different host plants.

Paresthesia of the inferior alveolar nerve (IAN) as the result of preapical inflammation or endodontic treatment is a rare but serious occurrence. The following case report describes the diagnosis and management of paresthesia related to an endodontic periodical lesion of a mandibular third molar.

evaluation of enlarged follicles with unerupted teeth is always important because some changes may occur. one of the extremely rare conditions seen in dental follicles is multiple calcifying hyperplastic dental follicle. we report a case of multiple calcifying hyperplastic dental follicle. radiographs showed that mandibular third molars had a pericoronal radiolucent zone delineated by a well-de...

A new species of Tozzita Kramer, 1964, Tozzita bifida sp. nov., is described and illustrated. The new species can be distinguished from the other species of the genus by the following characteristics: (1) forewing with commissural brown band; (2) pygofer with dentiform process on ventral margin and apex not spatulate; (3) subgenital plates with macroseta at apex; (4) style with preapical lobe d...

anti-müllerian hormone (amh) has been observed to decrease with the development of hemorrhagic anovulatory follicles (hafs) in mares. two studies were conducted to evaluate amh concentration in mares with hafs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of amh with the development of luteinised unruptured follicles (lufs). in study 1, amh and progesterone were e...

objective: in vitro ovarian follicle culture provides a tool to investigate folliculogenesis and may be used as an assisted reproductive technology )art(. this study aims to compare survival and development rates in mouse ovarian follicles after two and three dimensional in vitro cultures. methods: preantral follicles were isolated from the ovaries of 14-day old female mice and cultured in α-m...
