Několik příspěvků v tomto čísle cituje dílo A. Procy v souvislosti s problémem možné nenulové hmotnosti fotonu. Ukážeme zde, že dílo tohoto francouzského teoretického fyzika rumunského původu je mnohem rozsáhlejší. Byl skutečně významným a všestranným fyzikem., In this year we commemorate 60 years since the death of Alexandru Proca, one of the greatest physicists of the 20th century. He was a French scientist of Romanian origin. He developed the vector meson theory of nuclear forces and the relativistic quantum field equations which bear his name (Proca‘s equations) for the massive, vector spin-1 mesons., Ivo Kraus., and Obsahuje seznam literatury
Práce podává přehled práce francouzského experimentálního psychologa Alfreda Bineta (1857–1911) v oblasti studia disociačních jevů. V úvodu jsou uvedeny základní profesní a biografické údaje a dále popis jeho díla v oblasti studia hypnózy, hysterie a obecně problematiky disociačních jevů. Pozornost je věnována hlavním dílům k této problematice, která jsou popisována chronologicky a v souvislosti s Binetovým odborným vývojem i širší situací v oboru psychologie. Práce představuje méně známé dílo francouzského psychologa přelomu 19. a 20., který se proslavil především studiem teorie a měření inteligence., The article reviews works of famous experimental psychologist Alfred Binet (1857-1911) in the area of dissociative phenomena studies. Introductory part of the article provides the basic professional and biographic information and further description of Binet’s work in the area of hypnosis, hysteria and generally area of dissociative phenomenon is given. Special attention is given to the main books written on these topics. The works are described in chronological order and in relation to Binet’s professional development. The article presents less known work of famous French psychologist of turn of 19th and 20th century, famous above all with the studies of intelligence., Radek Ptáček., and Obsahuje seznam literatury
The Tiebori Department of Phototrophic Microorganisms of the Institute of Microbiology received a donation from the Operational Programme, Research and Innovation for Development, for construction and operation of a new scientific research Centre of algal biotechnologies. The implementation phase (begun January 1, 2011) aims to develop new cultivation equipment and algal biomass processing practices for the production of biofuel, animal feeding, food supplements and for the isolation of valuable substances. The project will also focus on research in the area of photosynthesis, developing new measuring devices and educating students in these areas. and Ondřej Prášil a Petra Pfeiferová.
The consequences of epileptic seizures related to postictal inhibition in early postictal period include postictal analgesia. We studied this phenomenon over 96 h following flurothyl-induced seizures in adult male Wistar rats. Nociception of control (no seizure) and seizured groups were tested using the plantar and von Frey hair tests. We determined latency of forepaw and hind paw reactions using plantar tests and the number of von Frey hairs reactions. Shortly after seizures, longer plantar test latencies were seen relative to the control group. Before the seizures the plantar test reaction times were significantly shorter in forepaws than in hind paws. The effect disappeared post-seizure and surprisingly, it also disappeared at the corresponding time in controls; it reappeared after 48 h in the seizure group and after 24 h in controls. Differences in the von Frey hairs test occurred at 5 and 60 min post-seizure, however, these differences could not be explained by limb anatomy; although, different thermal and mechanical nociception mechanisms could be significant. The unexpected reactions in controls could be related to brief social and physical interactions between the two groups. and J. Mareš, R. Rokyta.
Growth factors are powerful molecules that regulate cellular growth, proliferation, healing, and cellular differentiation. A delivery matrix that incorporates growth factors with high loading efficiencies, controls their release, and maintains bioactivity would be a powerful tool for regenerative medicine. Alginate has several unique properties that make it an excellent platform for the delivery of proteins. Mild gelling conditions can minimize the risk of protein denaturation; moreover, alginate can serve as protection from degradation until protein release. Various modifications have been proposed to tune alginate binding and release proteins, simultaneously adjusting alginate degradability, mechanical stiffness, swelling, gelation properties and cell affinity. The primary objective of this article is to review the literature related to recent advances in the application of alginate matrices in protein delivery in regenerative medicine. A special emphasis is put on the relevance of delivery of growth factors and chemokine., E. Wawrzyńska, D. Kubies., and Obsahuje bibliografii
This article examines the thoughts of Ali Abd al-Raziq, an important Egyptian scholar and author of a book called Islam and the Bases of Rule (al-Islam wa Usul al-Hukm), published in 1925. In this work, Abd al-Raziq presented fundamental arguments in support of the separation of religion and politics, which were fully supported by a very original analysis of Islam's holy text, the Quran, as well as by the historical situation of the Muslim community at the time of the Prophet Muhammad. Although the publication of this book caused a great scandal in Egypt, with its author being forced to withdraw from Egyptian public life for quite a long period of time, the arguments contained in the book represent an important contribution to the debates about the desirable degree of linkage between Islam and politics in the Muslim world., Jan Kondrys., and Obsahuje bibliografii
