RATIONALE: Epithelioid trophoblastic tumor (ETT) is a very rare form of gestational trophoblastic disease (GTD) which arises from neoplastic proliferation of intermediate trophoblasts. Metastatic ETT of the lung is extremely rare in postmenopausal women. PATIENT CONCERNS: Here we describe a 50-year-old woman with a metastatic ETT of the lung showing increasing tracer uptake at PET/CT. DIAGNOSIS: Hematoxylin-eosin staining showed a tumor composed of nests of epithelioid cells with necrotic debris and peritumoral hyaline-like material...

Treatment of gestational trophoblastic diseases (GTD) involves surgery, radiotherapy and chemotherapy. Although, these therapeutic approaches are highly successful, drug resistance and toxicity remain a concern for high risk patients. This Chemoresistance has also been observed in the presence of cancer stem cells that are thought to be responsible for cases of cancer recurrence. In this study, we report the presence of previously unknown populations of trophoblastic stem-like cells (SLCs) that are resistant to the chemotherapeutic drug doxorubicin...

Hydatidiform Mole (HM) is the most common form of Gestational Trophoblastic Disease (GTD), defined by hyper-proliferation of trophoblastic cells. HM is typified as abnormal proliferation of extraembryonic trophoblastic (placental) tissues and failure of embryonic tissues development and is the only GTD with Mendelian inheritance, which can reoccur in different pregnancies. Moles are categorized into Complete Hydatidiform Moles (CHM) or Partial Hydatidiform Moles (PHM) and a rare familial trait, which forms a CHM and despite having androgenetic pattern, shows normal biparental inheritance, conceived from one sperm and egg...

Gestational trophoblastic disease (GTD) encompasses a range of trophoblast-derived disorders. The most common type of GTD is hydatidiform mole (HM). Some of HMs can further develop into malignant gestational trophoblastic neoplasia (GTN). Aberrant expression of microRNA (miRNA) is widely reported to be involved in the initiation and progression of cancers. MiRNA expression profile also has been proved to be the useful signature for diagnosis, staging, prognosis, and response to chemotherapy. Till now, the profile of miRNA in the progression of GTD has not been determined...

OBJECTIVES: Given the rarity of gestational trophoblastic disease (GTD), specialized regional and national centers for GTD have been established. These centers serve at least 3 purposes: to improve care for women with GTD, to enhance research though collaboration, and to educate other clinicians. This study was undertaken to understand the potential GTD knowledge gap by examining both patient and physician inquiries received at a specialized GTD center. METHODS: All electronic consults received by specialists at our center between March 2016 and March 2017 were analyzed...

Clostridium difficile infection is the leading cause of hospital-acquired diarrhea and is mediated by the actions of two toxins, TcdA and TcdB. The toxins perturb host cell function through a multistep process of receptor binding, endocytosis, low pH-induced pore formation, and the translocation and delivery of an N-terminal glucosyltransferase domain that inactivates host GTPases. Infection studies with isogenic strains having defined toxin deletions have established TcdB as an important target for therapeutic development...

Gestational trophoblastic diseases (GTD) correspond to several entities which all have a common pattern: hypersecretion of human chorionic gondotrophin by trophoblastic hyperplasia. Between 2010 and 2012, there were 4 maternal deaths due to GTD (choriocarcinoma). The ratio of maternal death caused by GTD was 0,16/100,000 living births which was similar to the rate from the 2007-2009 period. These deaths represented 1.6% from the whole maternal mortality and 3.3% of the direct maternal mortality. These four deaths occurred after delivery and the diagnosis of GTD was made between 60 and 180 days in the postpartum period...

Background: The hydatidiform mole (HM) is a precancerous placenta considered as a gestational trophoblastic disease (GTD). It may convert to more invasive forms of gestational trophoblastic neoplasia (GTN), endangering women’s health by more severe complications. Most GTN cases originate from HM, which is associated with uterine bleeding, preeclampsia and thyroid problems. Its etiology has not been adequately explored, but some risk factors have been reported. The aim of the present study was to assess any relationships between molar pregnancy and factors including mothers’ and husbands’ occupations...

Molar pregnancy is one of the components of a broader spectrum of diseases known as Gestational Trophoblastic Disease (GTD), presenting with amenorrhoea and irregular bleeding which may be rarely associated with passage of vesicles per vagina. However, it can rarely be associated with hyperthyroidism, which may be associated with clinical features of hyperthyroidism. The following is a report of a 20-year-old woman who presented with amenorrhea followed by irregular bleeding per vagina, thyromegaly and abnormal levels of thyroid hormones...

Network modeling in electromagnetics is an effective technique in treating scattering problems by canonical and complex structures. Geometries constituted of angular regions (wedges) together with planar layers can now be approached with the Generalized Wiener-Hopf Technique supported by network representation in spectral domain. Even if the network representations in spectral planes are of great importance by themselves, the aim of this paper is to present a theoretical base and a general procedure for the formulation of complex scattering problems using network representation for the Generalized Wiener Hopf Technique starting basically from the wave equation...

Quantification of cell-free DNA (cfDNA) in circulating blood derived from a transplanted organ is a powerful approach to monitoring post-transplant injury. Genome transplant dynamics (GTD) quantifies donor-derived cfDNA (dd-cfDNA) by taking advantage of single-nucleotide polymorphisms (SNPs) distributed across the genome to discriminate donor and recipient DNA molecules. In its current implementation, GTD requires genotyping of both the transplant recipient and donor. However, in practice, donor genotype information is often unavailable...

Class V myosin (myosin-5) is a molecular motor that functions as an organelle transporter. The activation of myosin-5's motor function has long been known to be associated with a transition from the folded conformation in the off-state to the extended conformation in the on-state, but only recently have we begun to understand the underlying mechanism. The globular tail domain (GTD) of myosin-5 has been identified as the inhibitory domain and has recently been shown to function as a dimer in regulating the motor function...

Gestational trophoblastic diseases (GTDs) are a group of diseases characterized by abnormal cellular proliferation of atypical trophoblasts. A hydatidiform mole is an abnormal pregnancy caused by genetic fertilization disorders, and it can be classified as a complete hydatidiform mole (CHM) or a partial hydatidiform mole. The aim of this study was to establish cell lines from CHMs and to characterize the cells for future studies concerning GTD. HMol1-2C, HMol1-3B, HMol1-8 and HMol3-1B were established from primary cultures of CHM explants following the introduction of different combinations of genes including human telomerase reverse transcriptase (hTERT), a mutant form of CDK (CDK4R24C), cyclin D1, p53C234, MYC and HRAS...
