Morphology and phylogeny of Henneguya oviperda infecting oocytes of Esox lucius, with description of parasite-induced histopathology.

Henneguya oviperda (Cohn, 1895) (Myxozoa: Myxobolidae) is a parasite infecting oocytes of the northern pike Esox lucius Linnaeus, 1758 (Actinopterygii: Esocidae). Infected oocytes are surrounded by all oocyte layers, some of them thinner and less visible than intact oocytes. A mature plasmodium of H.

Influence of skin-to-skin contact and rooming-in on early mother-infant interaction: a randomized controlled trial.

The objective of this research was to study influence of birth routines on mother-infant interaction at Day 4. The present research is part of a longitudinal study where mother-infant pairs were randomized by infant location and apparel. We intended to assess mother-infant interaction from videos filmed at Day 4.

Early contact versus separation: effects on mother-infant interaction one year later.

Background: A tradition of separation of the mother and baby after birth still persists in many parts of the world, including some parts of Russia, and often is combined with swaddling of the baby. The aim of this study was to evaluate and compare possible long-term effects on mother-infant interaction of practices used in the delivery and maternity wards, including practices relating to mother-infant closeness versus separation.

Methods: A total of 176 mother-infant pairs were randomized into four experimental groups: Group I infants were placed skin-to-skin with their mothers after birth, and had rooming-in while in the maternity ward.

Novel mechanism of human fetal growth regulation: a potential role of lanugo, vernix caseosa and a second tactile system of unmyelinated low-threshold C-afferents.

Novel hypothesis of human fetal growth regulation in amniotic fluid environment integrates lanugo, vernix caseosa and a second tactile system of unmyelinated low-threshold C-afferents - all three forming a unique natural instrument powerfully speeding fetal growth during mid-gestation and lowering its tempo at the end of gestation. Repeated oscillations of lanugo hairs encased by vernix caseosa during fetal movements in amniotic fluid activate highly sensitive mechanoreceptors connected to unmyelinated C-afferents, which prime function is to conduct originated impulses from all fetal skin dermatoms via spinal cord and to activate vagal sensory zone, hypothalamus and insular cortex, for concomitant promotion of the anti-stress effect through oxytocin release, and stimulation of fetal growth by the incretin effect of gastrointestinal hormones.

Maternal axillar and breast temperature after giving birth: effects of delivery ward practices and relation to infant temperature.

Background: Little is known about the development and control of skin temperature in human mothers after birth. The purpose of this study was to explore the effects of delivery ward practices and early suckling on maternal axillar and breast temperatures during the first 2 hours postpartum and to relate them to the infant's foot and axillar temperatures.

Methods: Three groups of 176 mother-infant pairs were randomized as follows--group I: infants lying prone in skin-to-skin contact on their mother's chest, named the "skin-to-skin group" (n = 44), group II: infants who were dressed and lying prone on their mother's chest, named the "mother's arms group" (n = 44), and group III: infants who were dressed and kept in the nursery, named the "nursery group" (n = 88).
