U ovom je radu moja namjera ponuditi novo objašnjenje sebstva iz teorijskih perspektiva biologije i dinamičkih sustava. To znači da podržavam ideju da je sebstvo posljedica bioloških kontrolnih mehanizama, bilo unutarnjih procesa ili kao ishod međudjelovanja organizma i okoliša. Iz perspektive teorije dinamičkih sistema, sebstvo se može razumjeti kao svežanj uzoraka proizlazećih iz prilagodbe živućeg sustava na uvjete okoliša. U prvom dijelu rada, sebstvo se razumijeva polazeći od tri obilježja živućih sustava koji su rezultat samoorganizacije organske materije: identitet, jedinstvo i samoodržavanje. U drugom dijelu, raspravljam o jednom od najvažnijih obilježja sebstva: svjesnom djelovanju. Značenju svjesnog djelovanja pristupa se kao da se sastoji od tri dijela: sprega organizma sa svijetom, upravljanje unutarnjim i vanjskim procesima te predviđanje. Zaključno, raspravljam o problemu veze između sebstva i autonomije, pri čemu razmatram sebstvo kao posljedicu stupnjeva slobode živućeg sustava.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.

Observation of subtle or early signs of change in spaceflight induced alterations on living systems require precise methods of sampling. In-flight analysis would be preferable but constraints of time, equipment, personnel and cost dictate the necessity for prolonged storage before retrieval. Because of this, various tissues have been stored in fixatives and combinations of fixatives and observed at various time intervals. High pressure and the effect of buffer alone have also been tried.Of the various tissues embedded, muscle, cartilage and liver, liver has been the most extensively studied because it contains large numbers of organelles common to all tissues (Fig. 1).

The review article discusses the possibilities of using fractal mathematical analysis to solve scientific and applied problems of modern biology and medicine. The authors show that only such an approach, related to the section of nonlinear mechanics, allows quantifying the chaotic component of the structure and function of living systems, that is a priori important additional information and expands, in particular, the possibilities of diagnostics, differential diagnosis and prediction of the course of physiological and pathological processes. A number of examples demonstrate the specific advantages of using fractal analysis for these purposes. The conclusion can be made that the expanded use of fractal analysis methods in the research work of medical and biological specialists is promising.
