Platinum is a metallic element, which may react with our cellular component through its involvement in cancer chemotherapy medications. Cisplatin is one of the most useful antineoplastic drugs against human ovarian carcinoma, which has the central element of platinum in its structure. The nature of chemical interaction between platinum and cellular macromolecules is yet to be understood. We exa...

Transition towards spatio-temporal chaos in one-dimensional interfacial patterns often involves two degrees of freedom: drift and out-of-phase oscillations of cells, respectively associated to parity breaking and vacillating-breathing secondary bifurcations. In this paper, the interaction between these two modes is investigated in the case of a single domain propagating along a circular array o...

A histological and electronmicroscopic study of bronchial carcinoids indicated that these tumours are argyrophilic in keeping with their occurrence in tissue of embryologically foregut origin. Normal bronchi contain cells that resemble, in their electronmicroscopic content, intestinal Kultschitzky-type cells. Characteristic of the carcinoid cell is the presence of intracellular neurosecretory g...

Numerous studies support the idea that the myofibroblast is a key cell responsible for the tissue contraction in Dupuytren's disease. In vitro models have been developed to study the underlying cellular basis of myofibroblast differentiation and contraction. Studies suggest that the growth factor TGF-beta 1 combined with mechanical stress can promote the differentiation of fibroblasts into myof...

Bamboo, as a natural hierarchical cellular material, exhibits remarkable mechanical properties including excellent flexibility and fracture toughness. As far as bamboo as a functionally graded bio-composite is concerned, the interactions of different constituents (bamboo fibers; parenchyma cells; and vessels.) alongside their corresponding interfacial areas with a developed crack should be of h...

Genetic algorithm(GA) is widely fit to various kinds of problem but to fit a GA in any problem, it is important to design a good chromosome structure. It is also important to create a good fitness function which can be applicable to designed chromosome. The purpose of this article is to identify the parameter related to a cellular network and also identify how these parameters can be used to cr...

Acknowledgements First of all, Mom and Dad, for being here all these years. My advisor, Prof. Patrizia Mentrasti, for having introduced me to cellular automata and for all these years of giving directions and tolerating my intemperances. Prof. Tommaso Toffoli, for having shared his expertise with me, and for being the person he is. Prof. Tullio Ceccherini-Silberstein, for suggesting a radical i...

A large number of studies have demonstrated the existence of metabolic covalent modifications in different molecular structures, which are able to store biochemical information that is not encoded by DNA. Some of these covalent mark patterns can be transmitted across generations (epigenetic changes). Recently, the emergence of Hopfield-like attractor dynamics has been observed in self-organized...

background there is currently great concern about the possible adverse effect of microwave radiation from cell phones. in addition, noise is one of the physical pollutants of modern societies. objectives the present study aimed to examine the separate and simultaneous effects of cell phone microwaves, noise, and their effects on sperm parameters and total antioxidant capacity in adult male rats...
