Colonisation with resistant Klebsiella pneumoniae in a Cambodian neonatal unit is driven by person-to-person transmission, transmissibility varies by sequence type, and antibiotic consumption generally increases the risk of acquisition.

Age-specific transcriptional responses to Flt3-ITD and cooperating Flt3/Runx1 mutations cause hematopoietic stem cell depletion and myeloid progenitor expansion during adult, but not fetal/neonatal, stages of development.

Combined optogenetics and electrophysiology in vivo identified the cellular substrate of hippocampal drive that initiates the oscillatory entrainment of prefrontal cortex in neonatal mice.

Pet1 neurons actively maintain cardiorespiratory tone and dynamic range in mouse neonates and critically support the recovery response to apneas, informing brain findings in the sudden infant death syndrome.

Neonatal mouse heart regeneration relies on the presence of mononuclear diploid cardiomyocytes, which unites this process with embryonic heart growth and adult heart regeneration.

A single neonatal inflammatory event induces long-term impairments in two forms of adult respiratory motor plasticity, an important aspect of the control of breathing for compensation after injury or disease.

Neonatal hyperoxia abrogates the circadian protection from influenza infection in recovered adults.

Hormonal concentrations found in over 7-day-old neonates favor CC17 GBS invasiveness in a process linked to intestinal M cells maturation and mediated by the CC17 GBS surface protein Srr2.

Measuring individual differences in noxious-evoked baseline sensitivity in neonates can substantially reduce sample sizes required in neonatal analgesic trials.

Volatile anesthetics impair hepatic tricarboxylic acid cycle function in adult and neonatal mice, with citrate accumulation driving a neonate-specific inhibition of beta-oxidation and ketosis through their increased relative sensitivity to malonyl-CoA.
