1. Basic heel prick test: inclusion of screening, diagnosis and criteria for early confirmation of congenital infection by Toxoplasma gondii
ABSTRACT Toxoplasma gondii can cross the placental barrier, causing fetal infection with potentially severe sequelae. The aim of this study was to evaluate whether the serological screening for toxoplasmosis should be included in the basic neonatal heel prick test in order to establish criteria for the confirmation and/or exclusion of the diagnosis of congen

2. Zika virus damages the human placental barrier and presents marked fetal neurotropism
An unusually high incidence of microcephaly in newborns has recently been observed in Brazil. There is a temporal association between the increase in cases of microcephaly and the Zika virus (ZIKV) epidemic. Viral RNA has been detected in amniotic fluid samples, placental tissues and newborn and fetal brain tissues. However, much remains to be determined con

3. Desenvolvimento placentário em quatis: evolução filogenética em carnívoros? / Placental development in quati: phylogenetic evolution in carnivores?
The importance of preservation of brazilian wild species is based on knowledge of their distribution, behavior in the wild and in captivity, and the detailed description of their reproductive biology in order to perpetuate the specie. One of the main impacts of this study is the scientific details of the uterine environment versus the process of placentation

4. Placentação em roedores da família Cricetidae - Sigmodontinae / Placentation in rodents of family Cricetidae Sigmodontinae
Placenta is found only in mammals and it is result of the success of blastocyst implantation in the uterus, representing a functional organ to maternal-fetal exchanges and it is also an important endocrine organ. The Family Cricetidae and Subfamily Sigmodontinae include the rats and mice from South America. Due to the similarity of both the placenta morpholo

5. The role of HSP 60 in leucocytes cells of bovine placenta / O papel da HSP 60 nas células leucocitárias da placenta bovina
The maternal-fetal tolerance involves, besides the immune system, many peculiarities regarding the type of placenta and placentation. The bovine placenta is considered not invasive and, as consequence of a superficial implantation without endometrial invasion, it establishes itself as complex barrier that interposes between the maternal and fetal circulation

6. Parâmetros inflamatórios, imunológicos e histopatológicos da administração prolongada da Ipomoea carnea em ratos: 1. Avaliação em animais adultos 2. Estudo perinatal / Inflammatory, immunological and histopathological parameters of prolonged administration of Ipomoea carnea in rats: 1. Evaluation of adult animals 2. Perinatal study
The aim of this study was to evaluate the toxic effect of I. Carnea and its toxins on the immune system of rats, and to evaluate its effects on mothers and offspring when administered to dams during gestation or lactation. An alkaloid-rich plant extract (RAF) was added to drinking water to obtain doses equivalent to 3.0 and 15.0g/kg of dry leaves for 14 and

7. Placentation in rock cavies, Kerodon rupestris (Wied, 1820) / Placentação em mocós, Kerodon rupestris Wied, 1820
Placentation studies of fourteen rock cavy females in different gestation phases were conducted. Females were pre-anesthetized associating ketamine chloridrate (15mg/kg) and midazolan (1mg/kg). Soon afterwards, they were anesthetized by isoflurane inhalation in association with oxygen at 100% saturation. After anesthesia, the surgery allowed to exhibit fetal

8. A barreira placentária em cães (Canis familiaris, Linnaeus, 1758): fluxo sanguíneo materno-fetal / The placental barrier in dogs (Canis familiaris, Linnaeus, 1758): maternal-fetal blood flow
Este estudo define a inter-relação microvascular materno-fetal e o desenvolvimento dos hematomas placentários durante diferentes períodos gestacionais em cães SRD. Placentas de 20, 35, 45 e 55 dias da prenhez foram perfundidas e fixadas para a investigação histológica e confecção de moldes vasculares, injetados com Mercox, e submetidos a corrosão

9. Estudo Macro e Microscópico da Placenta de Termo de Capivara (Hydrochaeris hydrochaeris - Carleton, M. D. 1984) / Macroscopic and microscopic study of mature capybara placenta (Hydrochaeris hydrochaeris - CARLETON, M. D. 1984)
South and Central America are the natural habitat of the capybara, in the areas that go from Panama to Argentina, including the Andes region. These animals are herbivorous, diurnal, semi-aquatic, gregarious and docile; they live in large groups and are potentially important for the production of high quality meat, skin and oils, largely utilized in popular m

10. Targeting and crossing of the human maternofetal barrier by Listeria monocytogenes: Role of internalin interaction with trophoblast E-cadherin
Listeria monocytogenes produces severe fetoplacental infections in humans. How it targets and crosses the maternofetal barrier is unknown. We used immunohistochemistry to examine the location of L. monocytogenes in placental and amniotic tissue samples obtained from women with fetoplacental listeriosis. The results raised the possibility that L. monocytogene

11. The Trophoblastic Epithelial Barrier Is Not Infected in Full-Term Placentae of Human Immunodeficiency Virus-Seropositive Mothers Undergoing Antiretroviral Therapy
To study the mechanism of the placental barrier function, we examined 10 matched samples of term placentae, cord blood, and maternal blood obtained at delivery from human immunodeficiency virus (HIV)-infected mothers with children diagnosed as HIV negative in Sweden. All placentae were histologically normal, and immunochemistry for HIV type 1 p24 and gp120 a

12. Drug transporters in the human blood-placental barrier
Studies on the increasing number of transporters found in the placental barrier are gaining momentum, because of their tissue-specific expression, significance in physiology and disease, and the possible utilization of the emerging knowledge in pharmacology. In the placenta, both syncytiotrophoblast and fetal capillary endothelium express transporters. Fetal
