Misbehavior by rats, in the form of unnecessary and species-typical pawing, nosing, carrying, chewing, and retrieving a rolling ball bearing, was produced by pairing the ball bearing with food (Pavlovian procedure, Experiments 1 and 2) or by requiring contact with the ball bearing for food (operant procedure, Experiments 4 and 5). Misbehavior occurred both(More)
Specific IgG subclasses were investigated in two villages (Okoumbi and Ndjokaye) in southeast Gabon with different Loa loa transmission intensities of approximately 9,000 and 1,300 infective larvae (L3) per person per year, respectively. IgG subclasses were measured by an enzyme-linked immunosorbent assay (ELISA) using extracts of L. loa L3, microfilariae(More)
AIM The purpose of this randomized split-mouth clinical trial was to determine the active tactile sensibility between single-tooth implants and opposing natural teeth and to compare it with the tactile sensibility of pairs of natural teeth on the contralateral side in the same mouth (intraindividual comparison). MATERIAL AND METHODS The hypothesis was(More)
Adipokines, such as nicotinamide phosphoribosyltransferase (NAMPT), are molecules, which are produced in adipose tissue. Recent studies suggest that NAMPT might also be produced in the tooth-supporting tissues, that is, periodontium, which also includes the gingiva. The aim of this study was to examine if and under what conditions NAMPT is produced in(More)
UNLABELLED Extraction, periodontitis, or trauma can cause a reduction on the alveolar ridge. This could result in an insufficient alveolar bone width and height. Different techniques of vertical bone augmentation are described in literature. However, nowadays there is not enough evidence against lateral augmentation procedures to verify if these techniques(More)
Squamous odontogenic tumors (SOTs) are benign, locally infiltrative neoplasms that localize to the periodontium. In total, <50 cases have been reported since the first description of SOTs in 1975. Although the exact etiology of SOTs is unknown, the tumors are considered to derive from the epithelial cell rests of Malassez. SOTs are characterized by(More)
A method for the generation of a panoramic image from skeletal scintiscans of the jaws with the aid of a cylindrical projection of emission CT scans ist presented. Based on this "panoramic tomoscintigraphy" the jaw regions, arranged in the order of the arch segments, are evaluated numerically and the quantitative results are presented in a clearly organized(More)
