nowadays, new advances in the use of cell free fetal dna (cffdna) in maternal plasma of pregnant women has provided the possibility of applying cffdna in prenatal diagnosis as a non-invasive method. in contrary to the risks of invasive methods that affect both mother and fetus, applying cffdna is proven to be highly effective with lower risk. one of the applications of prenatal diagnosis is fet...

Cocaine exposure during pregnancy causes abnormality in fetal brain development, leading to cognitive dysfunction of the offspring, but the underlying cellular mechanism remains mostly unclear. In this study, we examined synaptic functions in the medial prefrontal cortex (mPFC) of postnatal rats that were exposed to cocaine in utero, using whole-cell recording from mPFC layer V pyramidal neuron...

The paper provides a uniform account of a number of locality effects, in particular, the Subject Condition, the Adjunct Condition, Richards’s (2001) tucking in effect, and the full Comp-trace paradigm, including (in addition to the basic cases) relative and extraposed clauses, the impossibility of short-subject topicalization, French que-qui alternation, and the effect of whmovement on agreemen...

Proliferative growth of the ventricular myocyte (cardiomyocyte) is primarily limited to fetal and early neonatal periods of development. In concert with the neonatal "transition" from proliferative to hypertrophic growth, ventricular remodeling of the nonmyocyte compartment is characterized by increased extracellular matrix synthesis/deposition and capillary angiogenesis. A role for locally gen...

Fetal neck is the site of important pathological changes, related to genetic, cardiovascular, lymphatic, endocrine systems. Among the main neck pathology are fetal hygroma, goiter, teratoma/sarcoma, hemangioma/lymphangioma. Posterior anomalies of the fetal neural tube, such as occipital myelomeningocele or iniencephaly may also be included in this area. Fetal hygroma is the main pathology, prob...

The loss of facilitated glucose transport of red cells occurring in the newborn pig was monitored in 11 density-separated cells from birth to a 4 wk of age. At birth there was a threefold increase in glucose permeability from the lightest cells to the most dense, suggesting that cells having progressively less glucose permeability are released into the circulation as gestation proceeds. Because...

During pregnancy in larger mammals, the maternal immune system must tolerate the fetus for months while resisting external infection. This tolerance is facilitated by immunological communication between the fetus and the mother, which is mediated by Major Histocompatibility Complex I (MHC I) proteins, by leukocytes, and by the cytokines secreted by the leukocytes. Fetal-maternal immunological c...

In the Mediterranean area, 50% of the beta thalassaemia mutations abolish or create a restriction endonuclease site in the beta globin gene. This study describes a new procedure for prenatal detection of these beta thalassaemia defects based on the direct visualisation, on an ethidium bromide stained polyacrylamide gel, of the discrete DNA fragments produced by restriction endonuclease digestio...
