Brain Awareness Week is a series of events held around the world to increase public awareness of the brain. Top Czech scientists attracted more then 1,300 students with lectures as part of the annual Brain Awareness Week that took place in the administration building of the Czech Academy of Sciences extending from 10-13 March 2008. and Gabriela Adámková.
This paper shows that there is a quantum-physical and evolution-biological perspective for (libertarian) free will, and that the so-called scientific arguments against it are in reality metaphysical arguments and insufficient. The paper also develops the idea of a nonphysical organ of higher organisms: the Domindar (Detector of macroscopic indetermination, and restrictor)., Tento článek ukazuje, že existuje kvantově-fyzikální a evolučně-biologická perspektiva pro (libertariánskou) svobodnou vůli a že tzv. Vědecké argumenty proti ní jsou ve skutečnosti metafyzické argumenty a nedostatečné. Příspěvek také rozvíjí myšlenku nefyzického orgánu vyšších organismů: Domindara (detektor makroskopické neurčitosti a omezovače)., and Uwe Meixner
Carnosine (CARN) is an anti-glycating agent able to quench superoxide, and to neutralize 4-hydroxynonenal. Trolox-carnosine (CARN-T) was synthesized because of its resistance against degradation and to improve CARN antioxidant capacity. We evaluated the impact of trolox (TRO), CARN and its derivative CARN-T on oxidative stress (OS) in brain during rat adjuvant arthritis (AA). The experiments were done on healthy, control arthritic and arthritic animals with administration of CARN 150 mg/kg b.w., TRO 41 mg/kg b.w. and CARN-T 75 mg/kg b.w. in a daily dose during 28 days. Antioxidants did not affect the body weight on day 14, but on day 28 TRO enhanced the weight reduction. On day 14 and 28 CARN-T and TRO reduced arthritic score. IL-1beta, MCP-1 and MMP-9 were measured in plasma on day 14. MCP-1 was decreased by CARN-T and TRO. All antioxidants reduced IL-1beta and MMP-9 levels. Malondialdehyde, 4-hydroxynonenal and protein carbonyls were increased in brain. CARN, CARN-T and TRO prevented higher lipid and protein oxidation in brain. CARN and CARN-T caused no weight reduction like TRO that has an advantage in inflammatory arthritis. Moreover the antioxidants administered had a similar therapeutic effects on arthritic score, markers of inflammation in plasma and OS in brain., S. Poništ, L. Slovák, V. Kuncírová, T. Fedorova, A.

Brain Awareness Week this year featured lectures by leading Czech neuroscientists and other brain scientists. It was the Czech Republic´s 18th observance, held on March 14-18, 2016 at the Czech Academy of Sciences main building. This issue of the Academic Bulletin presents an article by Dr. Alexandr Chvátal of the Institute of Experimental Medicine fo the CAS on what is known about glial cells at present. According to the general opinion, the central nervous system (CNS), whose principal purpose is the acquisition, processing and storage of information and response to external stimuli, to mainly composed of neurons that provide all of this above-mentioned functions. In fact, many glial cells are also involved in these functions. The aim of this brief overview is to correct some misconceptions about glial cells and to summarize some new insights about their role in nervous tissue functions. Many of the results were obtained by researchers from the Institute of Experimental Medicine of the Czech Academy of Sciences. and Autorem je redakce uvedená zkratkou red
