Objective: To develop novel fetal reference ranges for the characterization of the normal appearance of the Sylvian fissures (SF) along gestation and to apply them to fetuses with cortical abnormalities affecting the SF.
Methods: In this cross-sectional study, we used three-dimensional sonographic multiplanar reformatting (3D-MPR) to examine the fetal SF. Normal development was assessed in the second and third trimesters.
Objective: To describe fetal, clinical, radiological, morphological features of TUBB3 related syndrome.
Methods: We report two families each of two generations harboring a novel and a previously described heterozygous TUBB3 pathogenic variants. We compared these patients with other published TUBB3-related cases.
Background: Dandy-Walker malformation features agenesis/hypoplasia of the cerebellar vermis, cystic dilatation of the fourth ventricle and enlargement of posterior fossa. Although Dandy-Walker malformation is relatively common and several genes were linked to the syndrome, the genetic cause in the majority of cases is unknown.
Objective: To identify the mutated gene responsible for Dandy-Walker malformation, kidney disease and bone marrow failure in four patients from two unrelated families.

Preeclampsia (PET) is a hypertensive disorder that affects 2% to 8% of pregnant women. Recent observations support the hypothesis that upregulation of placental anti-angiogenic factors are responsible for the clinical manifestations of the disease. Neuropilin-1 (NP-1) is a transmembrane protein that acts as a coreceptor for vascular endothelial growth factor and as a regulatory protein in the immune system.

Objectives: To examine the feasibility of imaging the fetal cochlea in the early second trimester.
Methods: This study included 42 healthy fetuses of low-risk pregnancies between 14 and 16 weeks. The coronal head sections via sagittal and lateral acoustic windows were used for cochlear visualization.
Background: The presence of antibodies to thyroglobulin (Tg) is associated with fetal loss even in the absence of thyroid dysfunction. The aim of this study was to examine whether active immunization with Tg could elicit anti-Tg autoantibodies and reproductive failure without interfering with thyroid function.
Methods: BALB/c mice that were immunized with human Tg in complete Freund's adjuvant (CFA) or injected with only CFA were studied for the development of antibodies to Tg, T4, dsDNA, ssDNA and cardiolipin.
Neurodegenerative diseases including Alzheimer's disease are characterized by a progressive and selective neuronal loss via an apoptosis mechanism, and there is a growing body of evidence which supports a central role of mitochondria in this apoptotic cell death. Release of cytochrome c from the mitochondria to the cytosol is considered a critical step in apoptosis. Here we report that aluminum maltolate induces cytochrome c translocation into the cytosol as early as 3 hours in aged but not in young rabbit hippocampus.
