To what extent does early or excessive screen exposure affect children’s cognitive development? This is a question that is currently dividing scientists. A team led by Inserm researcher Jonathan Bernard at the Center for Research in Epidemiology and Statistics (Inserm/INRAE/Université Paris Cité/Université Sorbonne Paris Nord) studied the data of nearly 14,000 children from the French Elfe cohort for each child from the age of 2 to 5.5 years....
Emulsifiers are among the additives most widely used by the food industry, helping to improve the texture of food and extend its shelf life. Researchers from Inserm, INRAE, Université Sorbonne Paris Nord, Université Paris Cité and Cnam, as part of the Nutritional epidemiology research team (EREN-CRESS), studied the impacts on cardiovascular health of the consumption of emulsifiers.
Almost half of breast and ovarian cancers are connected to deficiencies in the biological systems that repair DNA breaks. Researchers from Institut Curie, Inserm and CEA reveal a hitherto unknown DNA repair mechanism involving a protein: PolꝊ, which is able to act during cell division.
Allergic diseases affect up to one third of the world's population, and their prevalence is on the increase. In order to develop more targeted and effective therapies, research is mobilizing to better understand the biological and cell mechanisms involved in the onset of allergies. Mast cells – a type of immune cell – is of particular interest to scientists and doctors, but there is little data about them at...
Teams from the internal medicine department of the Henri-Mondor AP-HP hospital, the Institut Necker – Enfants Malades, the Mondor Institute for Biomedical Research, the Institut Pasteur, Inserm, and the Paris-Est Créteil University studied immune memory after infection with the Omicron BA.1 variant in patients vaccinated with three doses of the messenger RNA COVID-19 vaccine.
Some HIV-1 carriers who have received an early antiretroviral treatment during several years are able to control the virus for a long term after treatment interruption. However, the mechanisms enabling this post-treatment control have not been fully elucidated. For the first time, teams of scientists from the Institut Pasteur, Inserm and the Paris Public Hospital Network (AP-HP), supported by ANRS | Emerging Infectious Diseases, have investigated and revealed how...
In a study of a cohort of 683 elderly Bordeaux residents followed up over 10 years, researchers from Inserm and Université de Bordeaux at the Bordeaux Population Health research center showed accelerated thinning of the retinal nerve fiber layer in the participants more exposed to air pollution, especially those who had a greater exposure to PM2.5 (fine particulate matter of a diameter of 2.5 microns or less). This study...
To understand the main determinants behind worldwide antibiotic resistance dynamics, scientists from the Institut Pasteur, Inserm, Université de Versailles Saint-Quentin-en-Yvelines and Université Paris-Saclay developed a statistical model based on a large-scale spatial-temporal analysis.
The summer of 2022 was the hottest ever recorded in Europe, characterized by an intense series of heatwaves that beat records of temperature, drought, and forest fires. Although Eurostat had already reported unusually high excess mortality for these dates, the fraction of mortality that could be attributed to the heat had not until now been quantified. And this is precisely what a study by scientists from Inserm and the...
In the face of childhood neurodevelopmental disorders, how can we get out of the therapeutic "dead end"? The answer could well be found in the genes of the proteasome – an intracellular mechanism that is responsible for removing defective proteins from the cell.
