The paper describes a case of twin pregnancy with complete hydatidiform mole (CHM). According to the data available in the literature, the concurrence of CHM with a normal placenta and a viable fetus occurs in 1 per 20,000-100,000 pregnancies, requires a differential diagnosis with partial hydatidiform mole and placental mesenchymal dysplasia, and is characterized by a high rate of complications. In this concurrence, the frequency of persistent trophoblastic disease is as high as 50%. In this case, the pregnancy ended in a spontaneous abortion at 16-17 weeks of pregnancy...

Osteosarcoma is the most common type of bone cancer, and accounts for ~3% of cancers that occurring in children. Chondromodulin‑I (ChM-I) is a 25 kDa glycoprotein that is expressed mainly in cartilage. ChM-I demonstrates anti‑angiogenic activity and has been suggested to inhibit endothelial cells from invading cartilage, and then has been shown to be an inhibitor of tumorigenesis. However, it remains unclear if ChM‑I has any direct anti‑tumorigenesis role on osteosarcoma. Therefore, the present study aimed to identify whether ChM‑I has any direct inhibit effect on human osteosarcoma cells...

INTRODUCTION: Hydatidiform moles (HM), presenting as complete (CHM) and partial (PHM) form, are rare pregnancy disorder. Diagnosis is based on clinical presentation, ultrasound imaging findings and pathological examination of products of conception. Protein p57, encoded by CKDN1C gene, is paternally imprinted and maternally expressed gene and provides quick insight in genetic basis of HM and allows distinction of CHM from all other conceptions. compare the preevacuational and pathohistological diagnosis with outcome of p57 immunostaining...

Diabetic retinopathy is a microvascular complication of type 2 diabetes and the leading cause of acquired blindness. In Taiwan, Chinese herbal medicine (CHM) is a popular adjunctive therapy. In this study, we investigated the CHM prescription patterns and their effects. We identified 23,701 subjects with type 2 diabetes in a database, and after matching for age and gender, 6,948 patients each were assigned to CHM and non-CHM groups. In the female subgroups, the cumulative retinopathy probability was lower for the CHM users than that for the CHM non-users (P < 0...

Aging is the gradual functional recession of the living tissues or organs caused by a variety of genetic and environmental factors together. Autophagy is a process of degrading cytoplasmic components mediated by lysosomes in eukaryotic cells. Kidney is a typical target organ of aging. Autophagy regulates renal aging. Decrease in autophagy can accelerate renal aging,whereas,increase in autophagy can delay renal aging. During the process of regulating renal aging,the mammalian target of rapamycin (mTOR) and its related signaling pathways including the adenosine monophosphate activated protein kinase (AMPK)/mTOR,the phosphatidylinositol 3-kinase (PI3K)/ serine-threonine kinase(Akt)/mTOR,the AMPK/silent information regulation 1 (Sirt1) and transforming growth factor β (TGF-β) play the important roles in renal aging...

Choroideremia (CHM) is an inherited retinal dystrophy characterised by progressive degeneration of photoreceptors, retinal pigment epithelium (RPE) and underlying choroid. It is caused by loss-of-function mutations in CHM, which has an X-linked inheritance, and is thus an ideal candidate for gene replacement strategies. CHM encodes REP1, which plays a key role in the prenylation of Rab GTPases. We recently showed that an induced pluripotent stem cell (iPSc)-derived RPE model for CHM is fully functional and reproduces the underlying prenylation defect...

PURPOSE: Choriocarcinoma (CC) is the most malignant gestational trophoblastic disease that often develops from complete hydatidiform moles (CHM). Neither the mechanism of CC development nor its progression is yet characterized. We have recently identified EG-VEGF as a novel key placental growth factor that controls trophoblast proliferation and invasion. EG-VEGF acts via two receptors PROKR1 and PROKR2. Here, we demonstrate that EG-VEGF receptors can be targeted for CC therapy. EXPERIMENTAL DESIGN: Three approaches were used, i) a clinical investigation comparing circulating EG-VEGF in Control (n=20) and in distinctive CHM (n=38) and CC (n=9) cohorts, ii) an in vitro study investigating EG-VEGF effects on the CC cell line JEG3, and iii) an in vivo study including the development of a novel CC mouse model, through a direct injection of JEG3-luciferase into the placenta of gravid SCID-mice...

The formalization of expert knowledge enables a broad spectrum of applications employing ontologies as underlying technology. These include eLearning, Semantic Web and expert systems. However, the manual construction of such ontologies is time-consuming and thus expensive. Moreover, experts are often unfamiliar with the syntax and semantics of formal ontology languages such as OWL and usually have no experience in developing formal ontologies. To overcome these barriers, we developed a new method and tool, called Expert2OWL that provides efficient features to support the construction of OWL ontologies using GFO (General Formal Ontology) as a top-level ontology...

Choriocarcinoma is an uncommon malignant neoplasm, which can be either gestational or nongestational in origin. Distinction of these subtypes has prognostic and therapeutic implications. Twenty-two tumors were genotyped using polymerase chain reaction amplification of 15 short tandem repeat loci and the amelogenin locus (XY determination). DNA patterns from tumor and maternal tissue, as well as villous tissue from any available prior or concurrent gestation, were compared, to determine gestational versus nongestational nature (containing vs...

The gut microbiota dysbiosis is one of the risk factors in the progression from the advanced chronic kidney disease(CKD)to uremia, characterized by the reduction of probiotics and the increase of opportunistic pathogens including urease-related microbes, endotoxin-related microbes and toxin-related microbes, which can produce uremic toxins. According to the core point of "the gut-kidney axis" theory and "the chronic kidney disease-colonic axis" concept, the gut microbiota dysbiosis aggravates renal damage by accumulating uremic toxins and inducing the systemic micro-inflammation...

The increased availability of user-friendly and accessible computational tools for biomolecular modeling would expand the reach and application of biomolecular engineering and design. For protein modeling, one key challenge is to reduce the complexities of 3D protein folds to sets of parametric equations that nonetheless capture the salient features of these structures accurately. At present, this is possible for a subset of proteins, namely repeat proteins. The α-helical coiled coil provides one such example, which represents ≈ 3 - 5% of all known protein-encoding regions of DNA...

Irritable bowel syndrome (IBS) is one of the most common functional bowel disorders (FBD), which is characterized by recurrent abdominal pain, abdominal bloating/distention associated with defecation or changed bowel habits. Currently, there is no evidence of obvious anatomic or physiologic abnormalities on the routine diagnostic examinations. There are multiple pathological factors involved in IBS responsible for its heterogeneous nature, although the exact etiology and pathology of IBS are not well known and it is disappointed to develop biomarkers for this disorder...
