Heat, or cold? New insights of the functioning of temperature-sensitive ion channels may open the way for a new medicines development (31.1. 2023)
Two important mechanisms that explain exactly how information about pain or heat and cold is transmitted in the cell have been revealed in an international study by scientists from Lund University, with participation of experts from the Institute of Physiology of the CAS. Two studies were published in the journal Nature Communications.
Effect of preterm and caesarean births on breast milk quality (23.8. 2022)
Breast milk contains an ideal cocktail of nutrients and biologically active substances that are essential for the rapid growth and development of the baby. In a new study, researchers from the Institute of Physiology of the CAS have described how the quality of the primary milk - colostrum - is negatively affected by premature birth or caesarean section. They also found that complex lipids are present in breast milk, which are broken down by one of the milk enzymes, releasing anti-inflammatory substances. Thus, breast milk is an irreplaceable way of nutrition for babies even in cases of substandard births.
Czech institutions join together to fight the epidemic of obesity, diabetes and heart disease. They got a billion of EU money to do it. (30.6. 2022)
The National Institute for Metabolic and Cardiovascular Disease Research is established - the largest ever domestic project of this type, bringing together five centres of scientific, research and clinical excellence. The prestigious institutions will help patients with diseases of civilisation, which together account for many times more lives than cancer. Teams of experts from IKEM, the Institute of Physiology and the Institute of Organic Chemistry and Biochemistry of the CAS, Masaryk University in Brno and Charles University will work together to gain a deeper understanding of the causes of interconnected diseases, to develop new drugs and to increase the involvement of modern technologies in treatment.
Maternal daily rhythmic behavior supports the development of the fetal biological clock (28.6. 2022)
Before the internal biological clock of the fetus starts ticking, the rhythmic behaviour of the mother influences the function and development of this structure. The team of Alena Sumová from the Institute of Physiology of the Czech Academy of Sciences found this and published it in a new study in the journal PLOS Biology. This discovery contributes significantly to the understanding of the development of the internal clock and may find application in the treatment of premature babies.
Scientists have described the interaction of important proteins that are key to cell aging (27.4. 2022)
Stress causes a cascade of events in the body. At the cellular level, the transcription factor p53 also responds to stress, preventing normal cells from becoming cancer cells. Another transcription factor, FOXO4, also plays an important role. Under stress conditions, these proteins interact and together increase the production of the p21 protein, causing cells to enter a senescent or ageing state. The accumulation of such cells contributes to the aging of the organism.
