Selection of asymmetric cell fates can involve both intrinsic and extrinsic factors. Previously we have identified the bag-of-marbles (bam) gene as an intrinsic factor for cystoblast fate in Drosophila germline cells and shown that it requires active product from the benign gonial cell neoplasm (bgcn) gene. Here we present the cloning and characterization of bgcn. The predicted Bgcn protein is ...

Larval and pupal testes of Drosophila melanogaster were fixed with a methanol/acetone fixation procedure that results in good preservation of cell morphology; fixed cells viewed by phase-contrast optics exhibit most of the structural details that can be seen in live material. Fixed testis preparations were treated with anti-tubulin antibodies and Hoechst 33258 to selectively stain microtubules ...

OBJECTIVE The purpose was to compare angular and linear measurements generated in digital cephalometric radiographs and cephalograms synthesized from three-dimensional images. METHODS Twenty-six individuals (12 men and 14 women) with mean age of 26.3 years were selected. Digital cephalometric radiographs and CBCTs were taken on the same day. The images were imported and analyzed on Dolphin Im...

A study of the craniofacial complex in four 47, XXX Finnish females, or females with an extra X chromosome, was carried out using cephalometric analysis comprising linear and angular measurements. The lengths of the anterior and posterior cranial bases, the calvarium, mandibular ramus and posterior and upper anterior face heights were found to be significantly shorter than in female controls, w...

AIM In this teleradiographic study, the authors investigate the correlations between facial kind, breathing pattern and cephalic posture. METHODS The research was conducted on a 94 schoolchildren sample. For each patient teleradiographic analysis in-L-L projection and rhinomanometric examination were performed. On the basis of clinical evidences, rhinomanometric results and nasopharyngeal space...

Pycnodysostosis is a rare genetic disorder and was first described in 1962 by Maroteaux and Lamy. The incidence of this anomaly is estimated to be 1.7 per 1 million births. The principal characteristics of this disorder are short stature, prominent eyes with blue sclera, beaked nose, cranial dysplasia, exposed fontanelles and cranial sutures, clavicular dysplasia, total/partial dysplasia of the...

Background. Gender identification by using skeletal is an important tool in forensic, medico-legal, bioarkeology, and anthropology. Traditional morphological methods depended on the anthropologist subjectivity that caused a significant difference among observer. This study aims to develop discriminant function for gender prediction Surabaya-Indonesia population age ranges 15-25-year-olds panora...

Introduction: Modification of overjet and posterior crossbite (PC) can affect the maximum bite force (MBF), in turn affecting the shape of the gonial angle (GA). Aims: To analyze MBF in PC and the correlation between MBF and GA in adults. Method: The evaluation was performed in 160 individuals, i.e., 88 men and 72 women (aged 18 to 39 years), divided into two groups: without PC, comprising 130 ...
