Ultrastructural localization of Ca2(+)-binding sites in the middle ear mucosa of the rat.
1990
Cations were precipitated with potassium-pyroantimonate in the middle ear mucosa of the rat and the distribution of the formed precipitates was studied by electron microscopy. The precipitate density in various cells of the different epithelia of the middle ear mucosa was determined on electron micrographs by counting the number of precipitates per unit area. Electron spectroscopic imaging was also performed to obtain information about the spatial distribution of the precipitates and their elemental composition.

Nb-90 - a potential PET nuclide: production and labeling of monoclonal antibodies
2012
Abstract Fast progressing immuno-PET gives reasons to develop new potential medium-long and long-lived radioisotopes. One of the promising candidates is 90Nb. It has a half-life of 14.6 h, which allows visualizing and quantifying processes with medium and slow kinetics, such as tumor accumulation of antibodies and antibodies fragments or polymers and other nanoparticles. 90Nb exhibits a high positron branching of 53% and an optimal energy of β + emission of E mean=0.35 MeV only. Consequently, efficient radionuclide production routes and NbV labeling techniques are required. 90Nb was produced by the 90Zr(p,n) 90Nb nuclear reaction on natural zirconium targets. No-carrier-added (n.c.a.) 90Nb …
Klinisch-experimentelle Studie zur szintigraphischen Darstellung maligner Kopf-Hals-Neoplasien mit57Cobalt-Bleomycin
1975
Tumorscanning of malignomas and their metastatic nodules in head and neck is an enrichment of diagnostic possibilities. For the examination such substances can be used, which are tumoraffine and well to mark with a radio-isotope. Therefore we have marked the cytostatic drug Bleomycine with 57Co. Scans were performed with the Anger-Camera 4 to 6 hrs after intravenous injection of 1 mCi 57Co-Bleomycine. 60 patients with different malignomas have been examined, 46 with tumor-localization in head and neck, the others in thoraxabdomen. 34 (85%) of the head and neck malignomas could be demonstrated; 21 (81%) were squamous cell carcinomas, 13 (69%) sarcomas. The possibilities of this method are sh…
Our Assessment Using Palate Postoperative Problems Score (PPOPS): Tool for the Evaluation of Results in Palatal Surgery Techniques
2018
Obstructive sleep apnoea syndrome is a chronic condition characterized by frequent episodes of collapse of upper airways during sleep. Prevalence of the disease is settled at about 3–7%. Today, palatal surgery is a reference point in OSAHS treatment and there are many different surgical techniques. The purpose of our work is to compare post-operative results of palate surgery techniques used in our practice in OSAHS patients, studying the degree of patients’ satisfaction with a recent score recommended by Rashwan et al. called PPOPS (Palate Post-Operative Problems Score). A retrospective study was performed on a sample of 40 patients subject to different palate surgery techniques for OSAS. …
