Myofascial Pain.

Semin Neurol 2018 Dec 6;38(6):640-643. Epub 2018 Dec 6.

Department of Neurology, Boston University School of Medicine, Boston, Massachusetts.

Myofascial pain syndromes arise from acute and chronic musculoskeletal pain and often have a referred neuropathic component. It affects more than three quarters of the world's population and is one of the most important and overlooked causes of disability. The origins of pain are thought to reside anywhere between the motor end plate and the fibrous outer covering of the muscle, with involvement of microvasculature and neurotransmitters at the cellular level.

Potential Role of microRNA-183 as a Tumor Suppressor in Hepatocellular Carcinoma.

Cell Physiol Biochem 2018 Dec 6;51(5):2065-2072. Epub 2018 Dec 6.

Department of General Surgery of East District, The Second Hospital of Hebei Medical University, Shijiazhuang,

Background/aims: Disseminated tumors, known as metastases, are responsible for ninety-percent of mortality due to cancer. Epithelial to mesenchymal transition, a phenomenon required for morphological conversion of non-motile discoid shaped epithelial cells to highly motile spindle-shaped mesenchymal cells, is thought to be a pre-requisite for metastatic progression. Metastasis-associated 1 (MTA1) protein is a prime inducer of EMT and metastatic progression in all solid tumors including hepatocellular carcinoma (HCC). Read More

Hot spots for GPCR signaling: lessons from single-molecule microscopy.

Curr Opin Cell Biol 2018 Dec 3;57:57-63. Epub 2018 Dec 3.

Institute of Pharmacology and Bio-Imaging Center, University of Würzburg, Germany.

G protein-coupled receptors (GPCRs) are among the best-studied membrane receptors, mainly due to their central role in human physiology, involvement in disease and relevance as drug targets. Although biochemical and pharmacological studies have characterized the main steps in GPCR signaling, how GPCRs produce highly specific responses in our cells remains insufficiently understood. New developments in single-molecule microscopy have made it possible to study the protein-protein interactions at the basis of GPCR signaling in previously inconceivable detail. Read More

Longer schooling but not better off? A quasi-experimental study of the effect of compulsory schooling on biomarkers in France.

Soc Sci Med 2018 Nov 23;220:379-386. Epub 2018 Nov 23.

Department of Social and Behavioral Sciences, Harvard T H Chan School of Public Health, 677 Huntington Ave, Boston, MA, 02115, USA; CUNY Graduate School of Public Health and Health Policy, 205 East 42nd Street, New York, NY, 10017, USA.

Less schooling is associated with increased biological risks for chronic disease, but whether increasing years of schooling through policy interventions reduces these risks remains unclear. We examine the effect of a major education reform introduced in 1959 that raised the minimum school leaving age from 14 to 16 years in France, offering a unique natural experiment. We assess the causal impact of increased schooling duration on 16 biomarkers of cardiovascular, metabolic, organ and immune function in a large cohort of men and women born around 1953. Read More

Pulmonary impairment following respiratory viral infections is associated with high mortality in allogeneic hematopoietic cell transplant recipients.

Biol Blood Marrow Transplant 2018 Dec 3. Epub 2018 Dec 3.

Infectious Diseases, Infection Control and Employee Health, The University of Texas MD Anderson Cancer Center, Houston, Texas.

Introduction: Pulmonary impairment predicts increased mortality in many settings, and respiratory viral infection (RVI) causes considerable morbidity and mortality in allogeneic hematopoietic cell transplant recipients (allo-HCT). We hypothesized that pulmonary impairment following respiratory viral infection, defined as a decline of forced expiratory volume in 1 second values by ≥10%, may identify allo-HCT recipients at high risk for mortality.

Methods: We studied all allo-HCT recipients at our institution who had RVI with respiratory syncytial virus, parainfluenza virus, or influenza from 2004-2013 and had pre-RVI and post-RVI pulmonary function tests. Read More

Polyethylene glycol-decorated doxorubicin/carboxymethyl chitosan/gold nanocomplex for reducing drug efflux in cancer cells and extending circulation in blood stream.

Int J Biol Macromol 2018 Dec 3. Epub 2018 Dec 3.

College of Pharmacy, Gachon University, Incheon 21936, Republic of Korea. Electronic address:

Polyethylene glycol (PEG)-decorated doxorubicin (Dox)/carboxymethyl chitosan (CMC)/gold nanoparticles (AuNPs) have been developed for cancer therapy. CMC was used as a reducing and stabilizing agent for the fabrication of AuNPs and Dox was loaded onto AuNPs as a chemotherapeutic agent. Dox-loaded CMC-stabilized AuNPs (Dox/CMC-AuNPs) with a mean diameter of 104. Read More

Geodorum densiflorum rhizome lectin inhibits Ehrlich ascites carcinoma cell growth by inducing apoptosis through the regulation of BAX, p53 and NF-κB genes expression.

Int J Biol Macromol 2018 Dec 4. Epub 2018 Dec 4.

Department of Biochemistry and Molecular Biology, Faculty of Science, University of Rajshahi, Rajshahi 6205, Bangladesh. Electronic address:

A lectin with a molecular mass of 12 ± 1 kDa was isolated for the first time from Geodorum densiflorum (Lam.) rhizome (GDL). The lectin exhibited hemagglutination activity both in mice and human erythrocytes which was inhibited by 4-nitrophenyl-β-D-glucopyranoside among the tested 26 sugars. Read More

Study of the selenizing Codonopsis pilosula polysaccharides protects RAW264.7 cells from hydrogen peroxide-induced injury.

Int J Biol Macromol 2018 Dec 3. Epub 2018 Dec 3.

Key Laboratory of Traditional Chinese Veterinary Medicine and Animal Health in Fujian Province, Fujian Agriculture and Forestry University, Fuzhou 350002, PR China. Electronic address:

Codonopsis pilosula polysaccharides (CPPS) has been shown to possess a variety of biological activities. In previous study, CPPS was successfully modified to obtain its best selenizing Codonopsis pilosula polysaccharides (sCPPS). The purpose of this study was to investigate the protective effect of the selenizing derivative of CPPS (sCPPS) from HO-induced oxidative damage in RAW264. Read More
