The USF Health team's work was supported in part by a Zika Research Initiative grant from the Florida Department of Health. provides eligible reporters with free access to embargoed and breaking news releases. It’s finally starting to heat up again after winter in the northern hemisphere. "If we can better understand Zika virus vertical transmission and successfully block infection in maternal (decidual) cells early in the pregnancy, the virus will not pass through the placenta to reach the fetus and it is less likely to cause severe abnormalities," said Guzeloglu-Kayisli, the paper's lead author. Anne DeLotto DeLotto Baier A great textbook for those who want all the wonderful nitty-gritty details is Plant Physiology by Taiz and Zeiger. Biology Prefixes and Suffixes: -Osis Definiton. However, Dr. Ozlem Guzeloglu-Kayisli said, these particular trophoblasts resist Zika virus attachment and replication. Definition and Examples, What Is Coevolution? A subtype of fetally-derived placental cells known as syncytiotrophoblasts, in direct contact with maternal blood, are assumed to be the site where the Zika virus enters the placenta, leading to potential fetal infection. Watson and Cricks Discovery of the Double Helix . In this study guide, learn more about the ebola virus and the Ebola Virus Disease (EVD), its pathophysiology, causes, signs and symptoms, nursing care management, and interventions. The University of South Florida is a high-impact global research university dedicated to student success. The researchers showed, for the first time, that specialized cells lining the uterus (maternal decidual cells) act as reservoirs for trimester-dependent transmission of the virus through the placenta - accounting for both the fetus's greater susceptibility to first-trimester Zika infection and for the more serious congenital defects observed in early versus late pregnancy. The virus that causes glandular fever is known as Epstein-Barr virus. The Discovery of Hepatitis C The discovery of HCV was a major milestone in 20th-century medicine, and the 2020 Nobel awardees represent three critical periods of research on this important virus. The widespread global alarm caused by the spread of mosquito-borne Zika virus throughout the Americas in 2015-2016 dissipated after the virus all but disappeared in 2017. Neutrophils (also known as neutrocytes or heterophils) are the most abundant type of granulocytes and make up 40% to 70% of all white blood cells in humans. EurekAlert! is a service of the American Association for the Advancement of Science. A virus replicates in order to shed from its host—through mucus, snot, phlegm, and even our breath—as soon as possible, in great quantities, so that it can keep spreading. However, Zika poses the most concern for pregnant women, because up to one in 10 newborns of affected mothers suffer Zika-associated birth defects, including smaller than normal head size (microcephaly) that can lead to developmental disabilities and other health problems. Glandular fever mainly affects young adults. DNA Replication . Flu (influenza) Influenza (the flu) is caused by a virus… Physiology of the kidney. Zika virus (ZIKV) ZIKV is a single-stranded RNA virus of Flavivirus genus from Flaviviridae family. Hiatal hernia. The findings appeared Dec. 1, 2020 in the Journal of Immunology. Coronavirus (COVID-19) Resources. Can You Speak Biology? The proliferation of viral particles released from the maternal cells are then transmitted through branch-like vascular projections (villi) on the placenta's surface layer where they can infect fetal trophoblast cells otherwise resistant to Zika virus. To learn more about how Zika gets through the placental wall, the USF Health team began by investigating the cellular and molecular mediators of Zika virus replication. How to use in utero in a sentence. However, the pathogenic mechanisms of ZIKV-induced neurological complications in adults and congenital malformations remain unknown. Hirschsprung disease. - Demonstrated that tizoxanide, the active metabolite of FDA-approved antiparasitic drug nitazoxanide, effectively impeded Zika virus infection in both maternal decidual cells and fetal trophoblast cells. These resources will introduce you to basic biology principles so you can move on to more complex topics. - Found that the efficiency of viral replication was significantly greater in first-trimester decidual cells than in those from term pregnancies. The finding warrants further testing of tizoxanide to block perinatal transmission of Zika virus and thereby protect the fetus from harmful outcomes, the researchers conclude. Herpes simplex virus infections. Zoonotic diseases. Hypertension (high blood pressure) is a disease of vascular regulation resulting from malfunction of arterial pressure control mechanisms (central nervous system, rennin-angiotensinaldosterone system, extracellular fluid volume.) What Is a Cladogram? Viruses can cause persistent infections in which they go dormant and can be reactivated at a later time. ... Zika virus infection. The IARS is committed to supporting our members who are addressing this illness on the front lines in any way we can. Glandular fever is the common term used to describe an acute viral infection called infectious mononucleosis. Gavin Publishers are combination of Open Access Journals and International Conferences. 813-598-0643, Copyright © 2021 by the American Association for the Advancement of Science (AAAS), University of Pennsylvania School of Medicine, University of South Florida Health (USF Health) Morsani College of Medicine. New research findings correlate with clinical observations of more fetal abnormalities and other Zika-related health problems in late versus early pregnancy, IMAGE: Ozlem Guzeloglu-Kayisli, PhD, associate professor of obstetrics and gynecology at the USF Health Morsani College of Medicine, was the paper's lead author and a co-principal investigator of the Zika study.... They form an essential part of the innate immune system, with their functions varying in different animals.. Barrow et al. Our hijacked cells serve as virus factories, reading the virus’s RNA and making long viral proteins to compromise the immune system. Pituitary adenoma. What Are the 8 Main Levels of Biological Taxonomy? While most Zika-infected adults show no symptoms, the virus can cause minor flu-like symptoms, and in rare cases has been associated with Guillain-Barre syndrome. Zika Virus; National Institutes of Health. Do Hand Sanitizers Work Better Than Soap and Water? Disclaimer: AAAS and EurekAlert! EurekAlert! How Does the Prefix (Arthr-) Relate to a Joint? All our journals are Double Blind Peer Reviewed Journals. Zika has also been linked to pregnancy complications, including preterm birth, preeclampsia and miscarriage. They are formed from stem cells in the bone marrow and differentiated into subpopulations of neutrophil-killers and neutrophil-cagers. "Moreover, trimester-dependent responses of decidual cells to Zika virus help to explain why pregnant women are susceptible to Zika infection and why the subsequent effects are more detrimental in the first trimester than in late pregnancy," the study authors wrote. ... Physiology and abnormalities of the pupil. Once the virus is inside our cells, it releases its RNA. The study was led by co-principal investigators Ozlem Guzeloglu-Kayisli, PhD, a USF Health associate professor of obstetrics and gynecology, and Charles J. Lockwood, MD, USF Health senior vice president, dean of the Morsani College of Medicine, and a professor of obstetrics and gynecology specializing in maternal-fetal medicine. The virus assembles new copies of itself and spreads to more parts of the body and—by way of saliva, sweat, and other bodily fluids—to other humans. We are currently handling more than 200 Journals and organizing 100 Conferences all over the world. DNA and RNA Structure . Herpes virus infections. Disclaimers.

Yet, resurgence remains possible in areas where the Aedes aegypti mosquito is prevalent, and there is no treatment or vaccine available for Zika virus infection.

BIOLOGY AND SOCIETYThe Global Threat of Zika Virus . Plant Hormones Effect Spring! Among their key findings, the researchers: - Identified a more than 10,000-fold higher expression of the Zika virus attachment-entry receptor in the maternal decidual cells than in the fetal trophoblasts. Over the past 10 years, no other public university in the country has risen faster in U.S. News and World Report's national university rankings than USF. Moreover, timing appears important. The key to understanding biology is a solid foundation in its most basic concepts. In utero definition is - in the uterus : before birth. There is no cure, specific treatment or vaccine for Zika virus... Related Information. Zika virus is a mosquito-borne virus.
