In this paper the recent population changes of the Wild Boar in different European countries is analysed through the study of hunting statistics. A simultaneous increase in numbers is observed throughout the whole area during the period 1965–1975. From 1975 onwards the population stabilizes itself apart from in peripheral areas like Finland. Potentially favourable factors which play a part in this process are discussed and certain reproductive and dispersive characteristics which favour its invasive behaviour are discussed. 相似文献

A correlation of the localization of functionally important regions with places having low and high values on twelve profiles built on a basis of amino acid sequences was analysed using a broad set of proteins. The profiles of hydrophilicity, resemblance to the sequences of human proteins, flexibility, mutability and others were considered. The resemblance profile was plotted by the program fixing short similar fragments in the testing protein and 92 human ones. The active centres were shown to be located in the primary structure regions having relatively low values on the resemblance profiles. Similar effect was observed in the mutability and alpha-helicity profiles. The potential functionally important sites of the human leukocyte interferon and interleukin-2 isolated on the basis of the analysis of this profiles were in accord with the available literary data. 相似文献

Summary. Hepatitis B core antigen is one of the most promising protein carriers of foreign epitopes of various human and animal pathogens.
Chimeric HBcAg particles can be used as effective artificial immunogenes. Unfortunately, not all chimeric proteins are able
to be particulated. The dependence of correct or incorrect folding of chimeric proteins on physical and chemical properties
of inserts was studied with the help of ProAnalyst, SALIX and QSARPro computer programs. We have found that insertion of amino
acids with high hydrophobicity, large volume, and high β-strand index prevent self-assembling chimeric proteins. These factors are most important for the C-termini of inserts. Recommendations
for obtaining correct folding of chimeric HBcAg particles have been given.
