Between June 1989 and May 1991, 29,020 subjects were tested for anti-human immunodeficiency virus (HIV) antibodies; 1079 were seropositive. A big discrepancy existed between the high seroprevalence in the group 0-3 yr of age, 11.22%, and that of 0.43% in the adult population. Moreover, only a small percentage of the pediatric cases (4%) resulted from(More)
A novel lateral flow card (TS-Card pork) test was developed for the serological detection of Trichinella infected pigs. Based on extensive studies performed in Romania during 1999-2000 this test proved to be highly specific sensitive, rapid (3-12 minutes) and easy to use (no need for laboratory facilities). It can be used both for the detection of(More)
Physicists at CERN have recently experimentally discovered particles traveling faster than light: the neutrinos! The OPERA experiment, which sent sprays of neutrinos from CERN laboratory in Geneva, Switzerland, to INFN Gran Sasso Laboratory, Italy, found that neutrinos traveled underground 730 km faster than light could do. Dr. Antonio Ereditato of(More)
From 1998 to 2000, 5,267 horse sera were collected from several Trichinella regions in Romania. Sera were initially screened in laboratories in Romania, Serbia and Italy with an ELISA and a Western blot (Wb) using an excretory/secretory (ES) antigen and several conjugates (protein A, protein G, and sheep or goat anti-horse). Differences in serology results(More)
OBJECTIVE To evaluate the effectiveness at different points in time, of recombinant human platelet-derived growth factor-BB (rhPDGF-BB) coated onto a beta-tricalcium phosphate (β-TCP) carrier compared to β-TCP alone, or to recombinant human growth/differentiation factor-5 (rhGDF-5) adsorbed onto a β-TCP scaffold in intraosseous periodontal defects.

We present in this paper a fast method for the reconstruction of the dental 3D structure using the images obtained from Cone Beam Computed Tomography (CBCT). A high-quality visualization of the dental tissues, including 3D reconstruction, is essential for the accurate diagnosis and treatment in dentistry. The segmentation for the dental CBCT images presents(More)
