The paper presents the dynamic characteristics of a continuous tank bioreactor for microbiological process, with a developed predator-prey food chain. The presence of the predator microorganism considerably influences the position and stability character of steady-states. There appears to exist a wide range of unstable steady-states and high-amplitude oscillations of state variables. Without automatic control, the system can operate only in unsteady conditions. From technological point of view, this circumstance is unfavorable. It was shown that oscillations can be removed by employing automatic control with continuous P or PI controllers. Moreover, the use of a controller with integrating element causes removal of the predator from the bioreactor. The paper discusses an application of this phenomenon for practical purposes.

Structure and dynamics of an undecamer DNA duplex containing a single α-anomeric deoxyadenosine residue placed in opposition to a thymidine unit have been studied using simulation of molecular dynamics in aqueous solution. Despite several noticeable deviations from the B-DNA duplex structure caused by the anomerisation, such as: West type puckering of the α-anomeric sugar, disrupted base stacking pattern and unstable duplex bending, the formation of a non-classical α-dA-T pair was observed. A novel way of visual presentation of trajectory data allowing high throughput screening of the conformational parameters is presented.

Aktyna jest uniwersalnym białkiem o strukturze dobrze zachowanej w toku ewolucji. W komórkach aktyna istnieje w równowadze pomiędzy formą monomeryczną i filamentową. Pomimo zachowanej w toku ewolucji struktury, aktyna pełni zdumiewająco wiele różnorodnych funkcji. Jest to możliwe dzięki zdolności aktyny do oddziaływania z wieloma białkami, wśród których znajdują się motory miozynowe oraz białka regulujące dynamiczną polimeryzację i depolimeryzację aktyny. Nadrzędnymi regulatorami filamentów aktynowych są tropomiozyny, rodzina superhelikalnych białek, które polimeryzują wzdłuż filamentowej aktyny, dzięki czemu stabilizują filamenty zapobiegając ich depolimeryzacji oraz kontrolują dostęp i aktywność białek wiążących aktynę. Tropomiozyny działają jako "stróże" filamentu, którzy kontrolują oddziaływania aktyny, co prowadzi do segregacji białek wiążących aktynę do swoistych przedziałów komórkowych gdzie białka te realizują określone funkcje komórkowe. W artykule zostały omówione zależne od tropomiozyny mechanizmy regulacji oddziaływań aktyny z niektórymi miozynami oraz z Arp2/3 i kofiliną - białkami, które inicjują rozgałęzianie, polimeryzację i depolimeryzację filamentów aktynowych.

Actin is a universal protein highly conserved in evolution. In cells, actin exists in equilibrium between a monomeric and filamentous form. In spite of a conservative structure, actin plays amazingly versatile functions. This is possible due to its interactions with numerous actin-binding proteins, among them with myosin motors and proteins regulating dynamic polymerization and depolymeriation of actin. Tropomyosins, superhelical proteins, which polymerize along the filament and stabilize actin by preventing its depolymerization, are superior actin filament regulators. Tropomyosins control the access and activity of various actin-binding proteins. Tropomyosins act thus as actin “gate-keepers” which control actin interactions leading to the segregation of actin-binding proteins into specific cell compartments where they perform specific cellular functions. This article discusses tropomyosin-dependent mechanisms of regulation of actin interactions with some myosins as well as Arp2/3 and cofilin - the proteins, which initiate branching, polymerization and depolymerization of actin filaments.
