Is physical activity always good for the heart?

Physical activity is thought to be our greatest ally in the fight against cardiovascular disease. But there may be significant variations in its protective effects across a range of different situations, such as regularly playing a sport, carrying heavy loads at work, or going for a walk with friends. These are the findings of a new study led by Inserm researcher Jean-Philippe Empana (U970 PARCC, Inserm/Université de Paris) in collaboration with Australian researchers.

Dysentery: Shigella, bacteria with adaptation to respiration

Imagerie montrant la déplétion de l'oxygène au sein de la muqueuse intestinale par Shigella (vert), induisant une hypoxie (rouge) au sein des foyers infectieux inflammatoires (neutrophiles: marqués à l'aide du Myelotracker, bleu).

Bacillary dysentery caused by the intestinal bacteria Shigella is a major health problem in tropical regions and developing countries. Complications from this infection lead to several hundred thousand deaths a year, primarily among infants. Researchers from Inserm and the Institut Pasteur have studied the mechanisms of Shigella virulence. They found that these bacteria are not only able to consume the oxygen in colonic tissue in order to grow and create foci of infection, but can also adapt their mode of respiration so that they can continue to grow once the oxygen in these foci has been used up.

Partially hydrolysed (hypoallergenic) baby formulas do not reduce allergy risks in infants

Hypoallergenic formulas are recommended for infants who are not exclusively breastfed and who are at risk of developing allergies. While it is assumed that such formulas reduce the development of allergies later in life, it is unclear whether this claim is true. A team of INRA and INSERM researchers have shown that the consumption of partially hydrolysed (hypoallergenic) formulas was not associated with a reduced risk of developing allergies, findings that were recently published in the journal Pediatric Allergy and Immunology.
