Aorto-Left Ventricular Tunnel Successfully Repaired Immediately After Birth.

We describe the unusual case of a patient with an antenatal aorto-left ventricular tunnel (ALVT) diagnosis and severe left ventricular (LV) dysfunction who underwent successful repair immediately after birth. To the best of our knowledge, no such case has been reported in the English literature. Our case demonstrated that neonates at the worst end of the ALVT spectrum can survive and achieve normalization of LV function through a timely and multidisciplinary approach.

Artificially reared mice exhibit anxiety-like behavior in adulthood.

It is important to establish experimental animal techniques that are applicable to the newborn and infant phases for nutrition and pharmacological studies. Breeding technology using the artificial suckling method without breast milk is very effective for the study of newborn nutrition. Using this method, we separated newborn mice from dams within 48 h of birth and provided them with artificial milk.
