On the basis of the new finding that the protein synthesis inhibitor cycloheximide (1, 4-[2-(3, 5-dimethyl-2-oxocyclohexyl)-2-hydroxyethyl]-2,6-piperidinedione) is able to competitively inhibit hFKBP12 (K(i) = 3.4 microM) and homologous enzymes, a series of derivatives has been synthesized. The effect of the compounds on the activity of hFKBP12 and their(More)
OBJECTIVE Tissue-engineered blood vessels (TEBVs) represent an innovative approach for overcoming reconstructive problems associated with extended vascular diseases by providing small-calibre vascular grafts. This study aimed to evaluate a novel biomaterial of bacterially synthesised cellulose (BC) as a potential scaffold for TEBV. METHODS Highly(More)
The O2 cost of breathing in fishes was studied in the tench (Tinca tinca). In fish lightly anaesthetised with urethane the respiratory water flowing out of the gills was measured by means of a chamber enclosing the gill slits. From the respiratory water flow and from the polarographically determined difference in O2 tension between inspired and expired(More)
We compared the objective and subjective evaluations of the results after correction of the earposition by the method of Converse with the results by the method of Reichert and Mustarde. The mean values obtained by the method of Converse correspond to the mean normal values. The patients are very satisfied with their results. A comparison of the results of(More)
The loss of the auricle is a dramatic event in terms of aesthetics of the face. Secondary reconstruction of the ear is difficult and complicated. Therefore, a replantation of the amputated part should be tried. Proper securing and transport of the amputate is essential, in addition to the patient being sent to a specialized clinic. An anatomically correct(More)
Peracetic acid Wofasteril) is increasingly made use of as a disinfecting fluid. Because of its high effectiveness it has found widespread use in medical practice. The action of Wofasteril on the oral mucosa during long-term action is studied by aid of an "oral tank". After a test period of 11 months peracetic acid only caused a slight ballooning of the(More)
Acetobacter xylinum produces highly crystalline cellulose extracellularly using glucose as a carbon source. The polymer formed is free of other biogenic compounds, separable in a simple way and characterized by its high water-absorption capacity. Stepwise solvent exchange from water to unpolar solvents leads to a drastic decrease of the water content of the(More)
Rabbits were exposed repeatedly to formalin irritation using a new oral tank which allows a chronical contact with the oral mucosa. In long-term experiments (11 months) a preneoplastic unrest of the epithelium with dyskeratosis could be produced. This new model of "oral tank" can be used for soluble and insoluble test substances for analyzing pathogenetic(More)
In follow-up examinations of young patients we often noticed upward displacement of the left shoulder in cases where left-sided posterolateral thoracotomy had been carried out. Finding little discussion of this side-effect in the literature, we undertook the present study. The shoulder girdle of 69 patients who had undergone surgery for coarctation of the(More)
Using a method of vascular pedicle ligation without skin incision, some minor differences were found between the progress of neovascularization in microvascular free skin-fat flaps and island flaps, both with and without 1-hr ischemia in rats. Viable flap areas were established following vascular pedicle ligation (both vessels or only artery or vein), on(More)
