MCC1019, a selective inhibitor of the Polo-box domain of Polo-like kinase 1 as novel, potent anticancer candidate

2019

Polo-like kinase (PLK1) has been identified as a potential target for cancer treatment. Although a number of small molecules have been investigated as PLK1 inhibitors, many of which showed limited selectivity. PLK1 harbors a regulatory domain, the Polo box domain (PBD), which has a key regulatory function for kinase activity and substrate recognition. We report on 3-bromomethyl-benzofuran-2-carboxylic acid ethyl ester (designated: MCC1019) as selective PLK1 inhibitor targeting PLK1 PBD. Cytotoxicity and fluorescence polarization-based screening were applied to a library of 1162 drug-like compounds to identify potential inhibitors of PLK1 PBD. The activity of compound MC1019 against the PLK1…

La tecnica del "triplo stretch" per l'estrazione rapida del feto nel cesareo d'emergenza.

2008

A modified Pfannenstiel access to the abdominal cavity for fast access to the fetus in emergency caesarean section is here described. It is easy to perform, easy to teach and to learn, and very effective; It allows the surgeon to deliver the fetus in less than 45 seconds starting from the beginning of skin incision.

743 Lysosomal Storage Disorders in Non-Immunological Hydrops Fetalis - More Common than Assumed?

2012

Background Although non immunological hydrops fetalis (NIHF) is a very rare disorder, the disturbance accounts for a disproportionate share (3%) of overall mortality in the perinatal period. Lysosomal storage disorders (LSD) are only exceptionally considered to be the cause of NIHF. The reported incidence is about 1%. On the other hand, in about 18% of all cases, NIHF is classified as idiopathic. Patients and methods We report four cases of transient NIHF due to LSD and reviewed the literature for LSD associated with NIHF. Results At present, 12 different LSD are described to be associated with NIHF. The majority of reported patients already had a family history of NIHF, which had not been …

Greenberg dysplasia: first reported case with additional non-skeletal malformations and without consanguinity

2001

In 1988 Greenberg et al. reported an association of fetal hydrops with irregular calcification and moth-eaten skeletal dysplasia. Here, we report on the first case of this disorder accompanied by additional malformations (omphalocele, intestinal malrotation, disturbed fingernails and toes, hypolobated lungs) in a German couple without consanguinity (karyotype 46,XY). Sonograpically, the fetus was characterised by tetraphokomelia, severe generalised hydrops, pulmonal hypoplasia and hepato-splenomegaly. Greenberg dysplasia should be considered in differential diagnosis in cases with severe fetal hydrops and phokomelia on antenatal sonography.

Acid ceramidase deficiency: Farber lipogranulomatosis, spinal muscular atrophy associated with progressive myoclonic epilepsy and peripheral osteolys…

2020

Abstract An inherited deficiency of the lysosomal enzyme ceramidase leads to accumulation of the sphingolipid ceramide in several organs such as skin, liver, brain and other tissues, resulting in a broad spectrum of clinical manifestations. The most common form, called Farber lipogranulomatosis, is characterized by subcutaneous skin nodules and a progressive hoarseness, in many cases also the central nervous system is affected. A lethal hydrops fetalis represents the most severe form. A ceramidase deficiency was also found in a few patients in whom neurological symptoms such as spinal muscular atrophy and myoclonus epilepsy dominated the clinical picture, in other adult patients peripheral …

Formation of Epidermal and Dermal Merkel Cells During Human Fetal Skin Development

1986

The origin of Merkel cells is still a matter of debate, specifically the question of whether they are derived from epithelial cells of the epidermis or from immigrated neural crest cells. As an argument for the latter hypothesis the occurrence of dermal, nerve-associated Merkel cells in human fetal skin has often been mentioned. Therefore, we analyzed the distribution of Merkel cells in epidermis and dermis of plantar skin of human embryos and fetuses, ranging in gestational age between 7 and 17 weeks. Merkel cells were identified by immunocytochemistry on frozen sections using antibodies against simple epithelium-type cytokeratins and by electron microscopy. In the 17-week-old fetus, 17% o…

Early patterns of electrical activity in the developing cerebral cortex of humans and rodents.

2006

International audience; During prenatal and early postnatal development, the cerebral cortex exhibits synchronized oscillatory network activity that is believed to be essential for the generation of neuronal cortical circuits. The nature and functional role of these early activity patterns are of central interest in neuroscience. Much of the research is performed in rodents and in vitro, but how closely do these model systems relate to the human fetal brain? In this review, we compare observations in humans with in vivo and in vitro rodent data, focusing on particular oscillatory activity patterns that share many common features: delta brushes, spindle bursts and spindle-like oscillations. …

Prenatal attachment in pregnant women subjected to fetal echocardiography

Olfaction in the fetal and premature infant: functional status and clinical implications.

2004

This article considers olfaction as a functioning source of information for the fetus and the neonate, born on term or prematurely. It aims to present how odors are involved in the sensory continuity between the prenatal and postnatal environments and how they influence the earliest adaptive responses of newborns in the realms of self-regulation, emotional balance, feeding, and social interactions.Finally, it evaluates odors as sensory means to ameliorate the physiologic and behavioral responses of preterm infants to the adverse impacts of separation from mother, nonoral feeding, or iatrogenic distress.

Prenatal attachment in women subjected to fetal echocardiography

2012

ackground The experience of fetal echocardiography (as advanced level screening, usually done between 19th and 23rd week of gestation) is a complex psychological condition for mothers. It can influences the relationship they structure with themselves and their future children. Sometimes this examination can result in a diagnosis of fetal congenital heart disease. This event could be critical for the psychological representation of the child, made by mother, pushing her to an emotional blockage or hyper involvement (Righetti, Di Bernardo, Maggino, 2008) . In continuity with specific studies on this topic (ibidem), this research study investigates the configuration of prenatal attachment bond…
