The odour of human milk: Its chemical variability and detection by newborns
2019
International audience; Human milk odour has for long elicited research interest with regard to its function in breastfeeding initiation. The present review aims to provide an overview of the behavioural effects of human milk odour in the human neonate, considering different types of response measures in a feeding or non-feeding context. Further, an overview of the current knowledge of odorant composition and factors influencing milk odour is provided by summarizing results from analytical studies using olfactometry, and addressing changes in milk odour due to storage, lactational stage, and maternal dietary intake of odorous substances. We finally highlight some issues for future research.
Environmental Enrichment During Adolescence Mitigates Cognitive Deficits and Alcohol Vulnerability due to Continuous and Intermittent Perinatal Alcoh…
2020
Perinatal alcohol exposure affects ontogenic neurodevelopment, causing physical and functional long-term abnormalities with limited treatment options. This study investigated long-term consequences of continuous and intermittent maternal alcohol drinking on behavioral readouts of cognitive function and alcohol vulnerability in the offspring. The effects of environmental enrichment (EE) during adolescence were also evaluated. Female rats underwent continuous alcohol drinking (CAD)—or intermittent alcohol drinking paradigm (IAD), along pregestation, gestation, and lactation periods—equivalent to the whole gestational period in humans. Male offspring were reared in standard conditions or EE un…
Motherhood‐induced gene expression in the mouse medial amygdala: Changes induced by pregnancy and lactation but not by pup stimuli
2021
During lactation, adult female mice display aggressive responses toward male intrud-ers, triggered by male- derived chemosensory signals. This aggressive behavior is not shown by pup- sensitized virgin females sharing pup care with dams. The genetic mechanisms underlying the switch from attraction to aggression are unknown. In this work, we investigate the differential gene expression in lactating females ex-pressing maternal aggression compared to pup- sensitized virgin females in the me-dial amygdala (Me), a key neural structure integrating chemosensory and hormonal information. The results showed 197 genes upregulated in dams, including genes encoding hormones such as prolactin, growth h…
Czy mleko modyfikowane może wydłużyć czas karmienia piersią?
2022
Karmienie naturalne jest najlepszym sposobem żywienia niemowlęcia. Położne i lekarze pediatrzy powinni dążyć do promocji karmienia naturalnego w celu wydłużania okresu karmienia piersią. W artykule autorstwa lekarza specjalisty pediatrii i gastroenterologii dziecięcej przedstawiono najważniejsze problemy związane z żywieniem niemowląt oraz choroby mogące spowodować przedwczesne zakończenie karmienia naturalnego. Podjęto próbę zdefiniowania praktycznych sytuacji klinicznych, w których czasowe zastosowanie mieszanki modyfikowanej może paradoksalnie pomóc, a nie przeszkodzić w utrzymaniu karmienia naturalnego.
