Effects of a single transient transfection of Ten-eleven translocation 1 catalytic domain on hepatocellular carcinoma.

PLoS One 2018 14;13(12):e0207139. Epub 2018 Dec 14.

College of Pharmacy, Nanchang University, Nanchang, Jiangxi, P.R. China.

Tumor suppressor genes (TSGs), including Ten-eleven translocation 1 (TET1), are hypermethylated in hepatocellular carcinoma (HCC). TET1 catalytic domain (TET1-CD) induces genome-wide DNA demethylation to activate TSGs, but so far, anticancer effects of TET1-CD are unclear. Here we showed that after HCC cells were transiently transfected with TET1-CD, the methylation levels of TSGs, namely APC, p16, RASSF1A, SOCS1 and TET1, were distinctly reduced, and their mRNA levels were significantly increased and HCC cells proliferation, migration and invasion were suppressed, but the methylation and mRNA levels of oncogenes, namely C-myc, Bmi1, EMS1, Kpna2 and c-fos, were not significantly change.

PLoS One 2018 14;13(12):e0209095. Epub 2018 Dec 14.

Division of Neonatology and Pediatric Molecular and Personalized Medicine Program, Department of Pediatrics, University of Rochester, Rochester, New York, United States of America.

Basement membrane (BM) is an essential part of the extracellular matrix (ECM) that plays a crucial role in mechanical support and signaling to epithelial cells during lung development, homeostasis and repair. Abnormal composition and remodeling of the lung ECM have been associated with developmental abnormalities observed in multiple pediatric and adult respiratory diseases. Collagen VI (COL6) is a well-studied muscle BM component, but its role in the lung and its effect on pulmonary epithelium is largely undetermined. Read More

Translating preventive chemotherapy prevalence thresholds for Schistosoma mansoni from the Kato-Katz technique into the point-of-care circulating cathodic antigen diagnostic test.

PLoS Negl Trop Dis 2018 Dec 14;12(12):e0006941. Epub 2018 Dec 14.

Swiss Tropical and Public Health Institute, Basel, Switzerland.

Background: Intervention guidelines against Schistosoma mansoni are based on the Kato-Katz technique. However, Kato-Katz thick smears show low sensitivity, especially for light-intensity infections. The point-of-care circulating cathodic antigen (POC-CCA) is a promising rapid diagnostic test detecting antigen output of living worms in urine and results are reported as trace, 1+, 2+, and 3+.

Glandular defects in the mouse uterus with sustained activation of TGF-beta signaling is associated with altered differentiation of endometrial stromal cells and formation of stromal compartment.

PLoS One 2018 14;13(12):e0209417. Epub 2018 Dec 14.

Department of Veterinary Integrative Biosciences, Texas A&M University, College Station, Texas, United States of America.

Uterine gland development, also known as adenogenesis, is a key uterine morphogenic process indispensable for normal uterine function and fertility. Our earlier studies have reported that overactivation of TGFB receptor 1 (TGFBR1) in the mouse uterus using progesterone receptor (Pgr)-Cre recombinase causes female infertility, defective decidualization, and reduced uterine gland formation, a developmental milestone of postnatal uterus. To understand mechanisms that underpin the disrupted uterine gland formation in mice with sustained activation of TGFBR1, we raised the question of whether early postnatal adenogenesis was compromised in these mice.

Ethnic background and children's television viewing trajectories: The Generation R Study.

PLoS One 2018 14;13(12):e0209375. Epub 2018 Dec 14.

Department of Public Health, Erasmus Medical Center, Rotterdam, The Netherlands.

This study, conducted in the Netherlands, evaluated the association between ethnic background and children's TV viewing time at multiple time points and its trajectory. We analyzed 4,833 children with a Dutch, Moroccan, Turkish, or Surinamese ethnic background from the Generation R Study, a population-based study in the Netherlands. Parent-reported television viewing time for children at ages 2, 3, 4, 6, and 9 years was collected by questionnaires sent from April 2004 until January 2015. Read More

Toll-like receptor chaperone HSP90B1 and the immune response to Mycobacteria.

PLoS One 2018 14;13(12):e0208940. Epub 2018 Dec 14.

University of Washington, Seattle, WA, United States of America.

Rationale: HSP90B1, also known as gp96, is a chaperone for multiple Toll-like receptors (TLRs) and is necessary for TLR-mediated inflammatory responses in murine myeloid cells. The molecule is also expressed in T-cells though its specific role is unknown. We hypothesized that human HSP90B1 regulates monocyte and T-cell responses to Mycobacterium tuberculosis (Mtb) and bacilli Calmette-Guerin (BCG) and that its variants are associated with susceptibility to TB disease.

Predictors of malaria Rapid Diagnostic Tests' utilisation among healthcare workers in Zamfara State.

PLoS One 2018 14;13(12):e0200856. Epub 2018 Dec 14.

Nigeria Field Epidemiology and Laboratory Training Programme, Abuja, Nigeria.

Introduction: Early diagnosis and prompt and effective treatment is one of the pillars of malaria control. Malaria case management guidelines recommend diagnostic testing before treatment using malaria Rapid Diagnostic Test (mRDT) or microscopy and this was adopted in Nigeria in 2010. However, despite the deployment of mRDT, the use of mRDTs by health workers varies by settings. Read More

Laparoscopic versus open appendectomy for complicated appendicitis.

Medwave 2018 Dec 11;18(8):e7370. Epub 2018 Dec 11.

Proyecto Epistemonikos, Santiago, Chile; Centro Evidencia UC, Pontificia Universidad Católica de Chile, Santiago, Chile; Departamento de Medicina Interna, Facultad de Medicina, Pontificia Universidad Católica de Chile, Santiago, Chile. Email: Address: Centro Evidencia UC, Pontificia Universidad Católica de Chile, Diagonal Paraguay 476, Santiago, Chile.

Introduction: The treatment of acute appendicitis using laparoscopy reduces the risk of wound infection, hospitalization time and return to normal activity. However, it increases the risk of intra-abdominal abscess, which is one the main complications of complicated appendicitis.

Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. Read More
