Developing and implementing a public health co-research program for Special Olympics athletes.

Individuals with intellectual and developmental disabilities are often the subject of research while rarely being included in formulating research questions, planning studies, and making decisions related to protocols and analyses. In turn, most research regarding people with intellectual and developmental disabilities is not carried out by researchers with disabilities themselves. We developed a co-research training program where individuals with intellectual and developmental disabilities were taught about research.

Assessment of contamination based on trace element concentrations in Gomphus flavipes (Odonata: Insect) larvae of the Upper Tisza Region.

Odonata larvae are frequently used to assess the contamination of aquatic systems, because they tolerate a wide range of chemical and biological conditions in freshwater systems. In early 2000, the sediments of the Hungarian section of the River Tisza and the River Szamos were strongly enriched with heavy metals by an accidental mining spill. Earlier studies demonstrated higher contamination levels in the Szamos than in the Tisza, based on sediment analysis.

[The fibrin and plasma-protein content of human thrombi].

The protein composition of cell-free thrombus contained in abdominal aneurysms of the aorta was investigated using PAGE and immunoreactivity after solubilization. 1. The dry weight was 18--29%, with minor differences between various locations.

Variable degradation of factor VIII-related protein in lyophilised concentrates of antihaemophilic factor (AHF).

Factor VIII-related properties (coagulant = VIII : C, 'Willebrand' factor = VIII R : WF, antigen = VIII R : AG) are measured in a constant proportion in normal plasma and certain preparations of highly purified factor VIII (relative ratios: 0.5--1.5).

Effects of amidination and chemical cross-linking on human factor VIII (antihemophilic factor).

The bifunctional reagent dimethyl suberimidate, reacting with primary amino groups of proteins, was used to cross-link highly purified human factor VIII. Reaction products were reduced with beta-mercaptoethanol or treated with Rhizopus arrhizus triglyceride lipase. The proportions of the dissociated subunits and their oligomers were calculated from the relative staining intensities of individual bands following polyacrylamide electrophoresis in the presence of sodium dodecyl sulfate.

[Study of nasal function by the spirographic method].

The authors performed spirographic investigations of respiration through the mouth, through both nostrils and separately through the right and the left nostrie in 44 people with normal anatomy of the nose. They discuss the methods applied as well as the physiologic changes in the respiratory function of the nose. They point out the practical importance of their study.
