Influence of abiotic factors on the lipid composition of <Emphasis Type="Italic">Ulva intestinalis</Emphasis> (L.) link (Chlorophyta) in small rivers of the El’ton Lake basin of the Caspian lowland

The content and composition of lipids of alga Ulva intestinalis (L.) Link, collected at ten stations located in the small rivers of an arid zone of the Caspian lowland, have been studied. The relations between the content of lipids of U. intestinalis and abiotic factors have been analyzed (mineralization level, temperature rate, saturation by oxygen, and the acidity of the environment). It is established that the level of mineralization of the water is the defining factor affecting the composition of membrane lipids.     

Respiratory and olfactory cilia molecular machines of locomotor apparatus

Physical activity of respiratory and olfactory cilia of animals and humans in the context of L.A. Blumenfeld concept, according to which protein molecules are “machines that perform chemical trans-formation” and create “a meaningful order”, has been investigated and analyzed.
