Interscapular brown adipose tissue (IBAT) activity is controlled by sympathetic nervous system, and factors that influence thermogenesis appear to be centrally connected to the sympathetic outflow to IBAT. Cold exposure produces a rise in BAT temperature, which is associated with an increased thyroid activity, elevated serum levels of 3,5,3’-triiodothyronine (T3), and an increased rate of T3 production. This study evaluated the effect of swimming training on 5’-triiodothyronine deiodinase (5’-D) activity in IBAT under normal environmental conditions and after short (30 min) cold exposure (TST stimulation test). 5’-D activity is lower in trained rats at basal condition, and TST increases 5’-D in IBAT of both untrained and trained rats. However, this increase is lower in trained rats. Training reduces the deiodinating activity in normal environmental conditions as well as after short cold exposure. Probably, other compensatory mechanisms of heat production are active in trained rodents.
A new myxosporean species, Trilosporoides platessae gen. et sp. n. (Multivalvulida), is described from the gallbladder of the plaice Pleuronectes platessa L. (Pleuronectidae) from Denmark. The myxospore of T. platessae is conical in side view, with a 24 µm long, pointed posterior projection. In apical view, the myxospore (diameter 9.4 µm) is round, trilobed and with three spherical polar capsules arranged peripherally, equidistant and opening peripherally through protruding tips. The polar capsules are of different sizes, one often larger than the others (diameter 3.3 µm vs. 2.5 µm). Apart from the long posterior projection, the myxospore of T. platessae differs from those of the three known species of Trilospora Noble, 1959 and from all genera within the order Multivalvulida Shulman, 1959 in the arrangement of the polar capsules. Trilosporoides platessae may temporarily be placed in the vicinity of the Trilosporidae.
Třinecké odkaliště poskytuje obraz sukcesních změn, kdy se mezi pionýrskými druhy vyskytují i vzácní a chránění živočichové a rostliny a z tohoto hlediska bude zajímavé sledovat vývoj společenstev na této lokalitě i nadále. and The settling pit in Třinec can serve as a model of succession changes, during which rare and protected animals and plants also appear among pioneer species. Therefore the further development of communities at this site is worth monitoring.
