Remarks on the morphology of the human temporomandibular joint in the fetal period.

Skeletons of human fetuses of different ages allow the study of the considerable transformations of the mandibular joint and the mandible in this relative short stage of life. The condyle is anchored in the mandible by a conical process. The tip of this cone extends to the anLage of the 2nd milk molar.

MR imaging of Her-2/neu protein using magnetic nanoparticles.

The aim of this study was to assess whether Her-2/neu expressing tumour cells can be detected in vitro as well as in animal tumour models with magnetic resonance imaging at 1.5 T. Magnetic nanoparticles (with relaxivities R 1, R 2 of 3.

Detection of bis(sulfosuccinimidyl) suberate binding in electrophoresis: determination of membrane sidedness of proteins.

The applicability of the membrane-impermeant protein cross-linker bis(sulfosuccinimidyl) suberate (BS(3)) to the determination of membrane sidedness of proteins was tested in 3T3-L1 cells and in erythrocytes. Binding of BS(3) to proteins was apparent in electrophoresis. In three proteins of 3T3-L1 cells, protein kinase-Cepsilon, protein kinase-Czeta, and glyceraldehyde-3-phosphate dehydrogenase, BS(3) action was detectable in SDS-PAGE with immunoblotting.

The cochleogram of the guinea pig.

The cochleogram is an important tool to relate properties of the cochlea (e.g. hair cell loss, damaged hair cells) to their position in the cochlear turns, to calculate the average hair cell density, and to measure the length of the whole cochlea.

Flow cytometry as a diagnostic tool for hereditary spherocytosis.

Flow cytometric analysis of eosin-5'-maleimide-labeled red blood cells has been proposed as a new method of identifying hereditary spherocytosis (HS). The aim of the present study was to analyze sensitivity and specificity of this method. Red blood cells from patients with HS (n = 58) revealed significantly lower mean channel fluorescence values than red blood cells from normal subjects (n = 110), unaffected HS family members (n = 8), and patients with other anemias (n = 44).

Treatment of chondral defects by hydro jet. Results of a preliminary scanning electron microscopic evaluation.

Introduction: Arthroscopic methods in treatment of chondral defects aim to get smooth cartilage surfaces. Mechanical and thermal methods are used. Often the clinical results are poor or moderate.

Influence of image-capturing parameters on digital X-ray radiogrammetry.

The purpose of this study was to evaluate the importance of different image-capturing conditions, which might influence the characteristics of radiographs and, consequently, impact calculations of bone mineral density (BMD) and Metacarpal Index (MCI) using digital X-ray radiogrammetry (DXR). Radiographs of the left hand of deceased males were acquired three times using systematically varied parameters: 4-8 miliamp seconds (mA); 40-52 kV; film-focus distance (FFD); 90-130 cm; film sensitivity, 200/400; and different image modalities (conventional vs original digital radiographs as well as digital printouts). Furthermore, the interradiograph reproducibility using both conventional equipment and printouts vs originals of digital images and the intraradiograph reproducibility (either conventional or digital printouts) were evaluated.

Frequency-specific cochlear damage in guinea pig after exposure to different types of realistic industrial noise.

For the causal evaluation of occupational hearing damage it is important to identify definitely the noise source. Here we tested, whether recordings of distortion product otoacoustic emissions (DPOAEs) in awake guinea pigs can distinguish the effects of different industrial noises. Six groups of 12 animals each were investigated before and over four months after a single 2 h exposure to specific, played-back industrial noise as well as before and for 2 months after impulse noise exposure.

[Problems in the development of a comprehensive three-dimensional databank of the human skull for the preoperative preparation of an exact implant for the treatment of bone defects].

Various human skulls were scanned with a laser scanner. Impressive Landmarks of the skull were determined and tested to be comparable stored in a uniform coordinate system for subsequent 3-d reconstruction. The Rhinion, the Nasion, the Spina nasalis anterior, the Prosthion, and the Opisthokranion were found to be very qualified for the adjustment in the median plane.
