Cellular quiescence is a reversible mode of cell cycle exit that allows cells and organisms to withstand unfavorable stress conditions. The factors that underlie the entry, exit, and maintenance of the quiescent state are crucial for understanding normal tissue development and function as well as pathological conditions such as chronic wound healing and cancer. In vitro models of quiescence have been used to understand the factors that contribute to quiescence under well-controlled experimental conditions. Here, we describe an in vitro model of quiescence that is based on neonatal human dermal fibroblasts...

The acquisition and early maturation of infant microbiota is not well understood despite its likely influence on later health. We investigated the contribution of the maternal microbiota to the microbiota of infant gut and nose in the context of mode of delivery and feeding. Using 16S rRNA sequencing and specific qPCR, we profiled microbiota of 42 mother-infant pairs from the GUSTO birth cohort, at body sites including maternal vagina, rectum and skin; and infant stool and nose. In our study, overlap between maternal vaginal microbiota and infant faecal microbiota was minimal, while the similarity between maternal rectal microbiota and infant microbiota was more pronounced...

OBJECTIVE: To examine changes that occur in infant and parent salivary oxytocin (OT) and salivary cortisol (SC) levels during skin-to-skin contact (SSC) and whether SSC alleviates parental stress and anxiety while also supporting mother-father-infant relationships. METHODS: This randomized crossover study was conducted in the neonatal intensive care unit (NICU) with a sample of 28 stable preterm infants and their parents. Saliva samples were collected from infants, mothers, and fathers on Days 1 and 2 (1/parent) for OT and cortisol measurement pre-SSC, during a 60-min SSC session, and a 45-min post-SSC...

The existing different modes of reproduction in monotremes, marsupials and placentals are the main source for our current understanding of the origin and evolution of the mammalian reproduction. The reproductive strategies and, in particular, the maturity states of the neonates differ remarkably between the three groups. Monotremes, for example, are the only extant mammals that lay eggs and incubate them for the last third of their embryonic development. In contrast, marsupials and placentals are viviparous and rely on intra-uterine development of the neonates via choriovitelline (mainly marsupials) and chorioallantoic (mainly placentals) placentae...

INTRODUCTION: Shunt systems are not perfect devices and can cause severe complications. Complications may originate from problems related to the valve, the patient, or the surgery and more common in neonates, infants, especially preterm by reason of the special characteristics these patients owned. We therefore have succesfully developed useful and viable surgical technique in order to provide helpful aspects to surgical issues mentioned above. TECHNIQUE: This technique includes \"reverse J\" shaped skin incision with nonintersecting the shun's hardware and distal catheter and to be reduced the wound problems to the minimum rates by opening \"bone groove\"...

Nasal continuous positive airway pressure (nCPAP) is utilized increasingly to treat pulmonary immaturity in premature neonates. Nasal injury is common with nCPAP use, with full thickness tissue loss at the columella among the most devastating complications.Columellar necrosis often imparts a full thickness injury to the overlying columellar skin, the medial crura of the lower lateral nasal cartilages, as well as the anteromedial inner nasal mucosal lining, and potentially the anterior septal cartilage. Consequently, the columella can become scarred and shortened...

The sesquiterpene nerolidol and the monoterpene limonene are potent skin-permeation enhancers that have also been shown to have antitumor, antibacterial, antifungal and antiparasitic activities. Because terpenes are membrane-active compounds, we used electron paramagnetic resonance (EPR) spectroscopy of three membrane spin labels combined with the fluorescence spectroscopy of three lipid probes to study the interactions of these terpenes with stratum corneum (SC) intercellular membranes. An experimental apparatus was developed to assess the lipid fluidity of hydrated SC membranes via the fluorescence anisotropy of extrinsic membrane probes...

INTRODUCTION: In Neonatal Intensive Care Unit (NICU), prematurely born infants undergo a range of skin breaking and painful procedures. At the same time, the spinal nociceptive system is in a sensitive developmental stage. Both neonatal repetitive painful procedures and their treatment can induce plasticity of the neonatal spinal nociceptive system, causing long-lasting alterations to pain processing and pain reactivity. METHODS: This review focuses on developmental processes related to the nociceptive network in the spinal dorsal horn and more specifically at mechanisms related to 1...

The early surgical management of omphalocele major in Africa predisposes neonates to surgical complications which are often worsened by the presence of associated anomalies. Conservative management using available escharotics results in early skin cover by secondary wound healing. This delays the need for fascial closure and avoids neonatal surgical risks thus improving survival. We present a case of omphalocele major that underwent spontaneous closure during conservative management with honey dressing without surgical intervention...
