The Roles of Dietary Glutamate in the Intestine.

Authors:
Daniel Tomé

Ann Nutr Metab 2018 3;73 Suppl 5:15-20. Epub 2018 Dec 3.

Glutamate (Glu), either as one of the amino acids of protein or in free form, constitutes up to 8-10% of amino acid content in the human diet, with an intake of about 10-20 g/day in adults. In the intestine, postprandial luminal Glu concentrations can be of the order of mM and result in a high intra-mucosal Glu concentration. Glu absorbed from the intestinal lumen is for a large part metabolized by enterocytes in various pathways, including the production of energy to support intestinal motility and functions. Read More

Predictive connectome subnetwork extraction with anatomical and connectivity priors.

Comput Med Imaging Graph 2018 Aug 25;71:67-78. Epub 2018 Aug 25.

Medical Image Analysis Lab, Simon Fraser University, Burnaby, BC, Canada.

We present a new method to identify anatomical subnetworks of the human connectome that are optimally predictive of targeted clinical variables, developmental outcomes or disease states. Given a training set of structural or functional brain networks, derived from diffusion MRI (dMRI) or functional MRI (fMRI) scans respectively, our sparse linear regression model extracts a weighted subnetwork. By enforcing novel backbone network and connectivity based priors along with a non-negativity constraint, the discovered subnetworks are simultaneously anatomically plausible, well connected, positively weighted and reasonably sparse.

Hyperoxia-Induced Cellular Senescence in Fetal Airway Smooth Muscle Cells.

Am J Respir Cell Mol Biol 2018 Dec 3. Epub 2018 Dec 3.

Mayo Clinic College of Medicine and Science, 12270, Department of Anesthesiology and Perioperative Medicine, Rochester, Minnesota, United States.

Supplemental O2 (hyperoxia; 30-90% O2) is a necessary intervention for premature infants, but contributes to development of neonatal and pediatric asthma, necessitating better understanding of contributory mechanisms in hyperoxia-induced changes to airway structure and function. In adults, environmental stressors promote formation of senescent cells that secrete factors (senescence-associated secretory phenotype; SASP), which can be inflammatory and have paracrine effects that enhance chronic lung diseases. Hyperoxia-induced changes in airway structure and function are mediated in part by effects on airway smooth muscle (ASM). Read More

What was the fate of human embryos following long-term cryopreservation (≥12 years) and frozen embryo transfer?

Hum Reprod 2018 Dec 4. Epub 2018 Dec 4.

Reproductive Medicine Center, The First Affiliated Hospital, Sun Yat-Sen University, 58, Zhongshan Road II, Guangzhou, China.

Study Question: Do human embryos survive long-term cryopreservation (CP) (≥12 years) and implant after frozen embryo transfer (ET)?

Summary Answer: Human embryos remain usable after long-term CP.

What Is Known Already: Several cohort studies have reported the live birth rate or neonatal outcomes of human embryos after CP for up to 5 years. Only a few case reports have described successful live births from human embryos after long-term CP up to 12 years. Read More

Assessment of oxidative damage and enzymatic antioxidant system activity on the umbilical cord blood and saliva from preterm newborns with risk factors for early-onset neonatal sepsis.

Rev Assoc Med Bras (1992) 2018 Oct;64(10):888-895

Dept. Of Neonatology - Municipal Hospital of Barueri/SP, Brasil.

Background: To determine the concentration of the Lipid Peroxidation Marker: Malondialdehyde (MDA), and Antioxidant Markers: Superoxide Dismutase (SOD), Glutathione Peroxidase (GPX), Catalase (CAL) in umbilical cord blood and in unstimulated saliva in the first 24 and 48 hours of life in the PTNB of mothers with and without risk factors for early-onset neonatal sepsis.

Methods: Cross-sectional study with the signing of informed consent by the pregnant women and application of a standard questionnaire classifying the PTNB in Group 1 or 2.

Results: Twenty-one PTNB were studied. Read More

Components of the antepartum, intrapartum, and postpartum exposome impact on distinct short-term adverse neonatal outcomes of premature infants: A prospective cohort study.

PLoS One 2018 5;13(12):e0207298. Epub 2018 Dec 5.

Department of Obstetrics, Gynecology and Reproductive Sciences, Yale University, School of Medicine, New Haven, Connecticut, United states of America.

We aimed to test the hypothesis that determinants of the perinatal clinical exposome related to the underlying etiology of premature birth (PTB) impact differently on select neonatal outcomes. We conducted a prospective longitudinal study of 377 singleton preterm neonates [gestational age (GA) at birth: 23-34 weeks] separated into three distinct contemporaneous newborn cohorts: i) spontaneous PTB in the setting of intra-amniotic infection/inflammation (yes-IAI, n = 116); ii) spontaneous PTB in the absence of IAI (no-IAI, n = 130), and iii) iatrogenic PTB for preeclampsia (iPTB-PE, n = 131). Newborns (n = 372) were followed until death or discharge. Read More

Characterisation of morphological differences in well-differentiated nasal epithelial cell cultures from preterm and term infants at birth and one-year.

PLoS One 2018 5;13(12):e0201328. Epub 2018 Dec 5.

Wellcome Wolfson Institute for Experimental Medicine, School of Medicine, Dentistry & Biomedical Sciences, The Queen's University of Belfast, Belfast, Northern Ireland, United Kingdom.

Background: Innate immune responses of airway epithelium are important defences against respiratory pathogens and allergens. Newborn infants are at greater risk of severe respiratory infections compared to older infants, while premature infants are at greater risk than full term infants. However, very little is known regarding human neonatal airway epithelium immune responses and whether age-related morphological and/or innate immune changes contribute to the development of airway disease.
