Age-Related Reference Ranges for Fetal Foot Length
2000
AIM The aim of this study was to establish age-dependent reference ranges for fetal foot length with gestation as well as for the femur/foot length ratio, based on a mathematical growth model. METHOD In a prospective cross-sectional study of 610 pregnancies with sonographically confirmed gestational age (< 12 weeks' gestation), fetal biometry was performed in addition to measurements of fetal foot length between 12 and 42 completed weeks of gestation. Reference ranges for the fetal foot and for the femur/foot length ratio were constructed with an overall coverage of 90% of the measured data, using a previously established method of determining reference bands for growth parameters. RESULTS …
Non-immune hydrops fetalis: Two case reports
2021
BACKGROUND Fetal hydrops is a serious condition difficult to manage, often with a poor prognosis, and it is characterized by the collection of fluid in the extravascular compartments. Before 1968, the most frequent cause was the maternal-fetal Rh incompatibility. Today, 90% of the cases are non-immune hydrops fetalis. Multiple fetal anatomic and functional disorders can cause non-immune hydrops fetalis and the pathogenesis is incompletely understood. Etiology varies from viral infections to heart disease, chromosomal abnormalities, hematological and autoimmune causes. CASE SUMMARY A 38-year-old pregnant woman has neck lymphoadenomegaly, fever, cough, tonsillar plaques at 14 wk of amenorrhea…
The development of anticipation in the fetus: A longitudinal account of human fetal mouth movements in reaction to and anticipation of touch
2013
Research suggests that fetuses open or close their mouth in relation to directed movements but it is unclear whether mouth opening anticipates the touch or is a reaction to touch, as there has been no analysis so far of (1) the facial area of touch and (2) the sequential ordering of touch and mouth movements. If there is prenatal development of the anticipation of touch we would expect the frequency of fetal mouth opening immediately preceding the arriving hand at the mouth area to increase with fetal age. Fifteen healthy fetuses, eight girls and seven boys, underwent four additional 4-D scans at 24, 28, 32, and 36 weeks gestation. Changes in the frequency of touch for different facial regi…
Mechanisms of protein expression in the rat optic nerve: Modifications by alcohol exposure
2005
espanolObjetivos: Nuestros trabajos previos han demostrado que el consumo abusivo de etanol durante la gestacion induce retraso en el desarrollo y alteraciones estructurales en los ojos y en la vision (Pinazo-Duran et al., Teratology 93; Eur J Ophthalmol 97; Stromland and Pinazo-Duran, Teratology 94; Alcohol Alcoholism 02). Nos proponemos estudiar a un nivel celular y molecular si el etanol modifica la expresion de proteinas marcadoras del desarrollo glial durante los estadios pre- y postnatal de la rata, que puedan contribuir a la dismorfogenesis del nervio optico. Metodo: Para estudiar las acciones del etanol sobre el desarrollo del nervio optico de ratas sometidas a un proceso de alc…

Ontogeny of the human amygdala.
2003
Data on the fetal development of the human amygdala is reviewed with special reference to major ontogenetic events. In the fifth gestational month, the inferior portion of the amygdala reveals cell-dense columns merging with the ganglionic eminence (proliferative zone) in Nissl-stained sections. These columns contain vimentin-positive fibers and can therefore be regarded as migrational routes. In the sixth and seventh months, distinct reorganization of the cytoarchitectonics takes place. The sequential occurrence of afferens can be visualized using anti-GAP-43; moreover, outgrowing axons appear to reach the periphery of the ganglionic eminence. The latter may thus represent an intermediate …
Karyotype analysis, nucleolus organizer regions and C-banding pattern of Eisenia foetida (oligochaeta, lumbricidae)
1991
The diploid number 2n=22 and haploid number n=11 found for Eisenia foetida from Palermo, Italy, confirm earlier data for this species from other localities. Analyses of silver-stained and C-banded mitotic and meiotic chromosomes suggest that a single chromosome pair has active NORs which correspond with C-positive regions. The occurrence of nucleolus activity during spermatogenesis of E. foetida is ascertained.
Fabrication and characterization of graphene field effect transistors (GFET)
2015
Graphene is a flat monolayer of carbon atoms tightly packed into a two-dimensional (2D) honeycomb lattice. This peculiarity is responsible of extraordinary physical properties. Graphene exhibits a strong ambipolar field effect and thanks to its huge charge carrier mobility, graphene is a suitable material for high frequency Electronics. Graphene field effect transistors (GFET) for high frequency applications have recently received much attention and significant progress has been achieved in this area. GFETs have been already made by using pre-patterned metal or graphene nanoribbon (GNR) back-gates and hexagonal boron nitride as a dielectric spacer. Among the most employed techniques for the…
Uskonnollisen johtajan puheesta seuraajien tekoihin : Muhammed Fethullah Gülenin poliittisesta ajattelusta
2015
Tämän pro gradu tutkielman tarkoituksena on tarkastella turkkilaisen imaamin, Muhammed Fethullah Gülenin poliittista ideologiaa, hänen ympärilleen muodostunutta sosiaalista Gülen-liikettä eli hizmet-palveluliikettä ja näiden kahden asemaa Turkin politiikassa. Lisäksi pohditaan uskonnon ja sekulaarin taistelua, uskonnon merkitystä politiikassa ja erityisesti Turkissa. Työssä pyritään avaamaan myös Gülen-liikkeen tavoitteita ja pyrkimyksiä. Päähahmo on kuitenkin vapaaehtoisesti Yhdysvalloissa maanpaossa elävä uskonnollinen johtaja, imaami Gülen. Pääasiallisina lähteinä käytän Gülenin omia, hänen seuraajilleen tarkoitettuja tekstejä, analysoidessani niiden merkityksiä poliittisessa viitekehyks…
Aspectos inmunogenéticos del HLA-G en el aborto de primer trimestre
2012
El objetivo del presente proyecto de tesis doctoral es investigar las moléculas del HLA-G y HLA-E desde el punto de vista inmunogenético en las detenciones espontáneas del embarazo en el primer trimestre de la gestación, puesto que ambos antígenos de histocompatibilidad, según la literatura, tienen un papel fundamental en el establecimiento de la tolerancia materno-fetal y en el mantenimiento del embarazo. Realizan funciones tan importantes como la inmunosupresión de células inmunes maternas para que el feto sea capaz de escapar del ataque del sistema inmunológico materno. Para la determinación de este objetivo utilizamos muestras de cariotipo embrionario normal, donde se desconoce la causa…
