Drug induced liver injury - FZU hosted a debate about a serious problem

Thu, 16/03/2023 - 11:42
Active substances of drugs, alone or in combination with each other, herbs and herbal supplements are metabolized by the human liver. This metabolization can be associated with irreversible damage or even death of the patient. There is no effective prevention against this problem. Additionally, there is no simple drug testing preclinical system to decipher hepatotoxicity issues undoubtfully at early stages of the drug development. Deeper understanding of drug-induced liver injury (DILI) mechanisms is the goal of an international team of experts from the Prospective European Drug-induced Liver Injury Network (PRO-EURO DILI Network), who met on March 9 and 10 at the Institute of Physics of the Academy of Sciences of the Czech Republic.

Remembering Vladimír Cháb

Tue, 07/03/2023 - 15:03
There are pieces of news that are hard to believe. This applies also to the one about the decease of Vláďa Cháb, who was known for his immeasurable vitality and sporting spirit. Unfortunately, his great scientific and sporting heart stopped on the night of March 5, 2023, at the age of 76. When I heard about a month ago that he was not in good health, I did not pay much attention to the news. I believed that there was no illness or obstacle that Vláďa’s spirit could not handle. Unfortunately, I was wrong.

Our ambition: to arrive with a laser-equipped truck and process nuclear reactor parts

Mon, 27/02/2023 - 16:45
In HiLASE Centre, a new generation of diode-pumped lasers with high average power and high repetition frequency has been developed for a long time. We talked to Jan Brajer, a leading expert from the HiLASE Centre, about colours of the laser as well as success in laser shock peening.

Constant Plane Shift Model: Structure analysis of martensitic phases in Ni50Mn27Ga22Fe1 beyond non-modulated building blocks

Mon, 20/02/2023 - 10:05
New method to obtain different martensitic phases in Ni-Mn-Ga-Fe alloy with simplified variant microstructures allows us to analyze the crystal structure of NM, 14M, and 10M martensites in greater detail. We found that the short crystallographic axes of different martensites at the same temperature have different lengths which suggests that the equilibrium NM structure building blocks cannot be used to build the crystal structures of 14M and 10M martensites. As a replacement for the NM building block model we introduce a constant plane shift model with identical shifting values of the nearest planes (110) along [ ] or [ ]. The work demonstrates that the value of plane shifting differs dramatically between martensites in agreement with ab initio calculations. The application of the constant plane shift and hard sphere models in modulated lattices for atomic-level twinning considerations will be discussed.
