BACKGROUND: Hepatitis E virus (HEV) is a leading cause of acute icteric hepatitis and acute liver failure in the developing world. During the last decade, there has been increasing recognition of autochthonous (locally acquired) HEV infection in developed countries. Chronic HEV infection is now recognised, and in transplant recipients this may lead to cirrhosis and organ failure. AIM: To detail current understanding of the molecular biology of HEV, diagnostic and therapeutic strategies and propose future directions for basic science and clinical research...

The B-cell lymphoma 2 (BCL2) family of proteins comprise key regulators of apoptosis and are implicated in the pathogenesis of many malignancies, including lymphomas and leukaemias. Targeting of BCL2 proteins can be directly toxic to tumour cells or render them more sensitive to chemotherapy. Inhibition of the anti-apoptotic functions of BCL2 proteins using structure-based design to produce specific inhibitors of protein-protein interactions has been achieved for BCL2, MCL1 and BCL-XL (also termed BCL2L1), providing an armamentarium of new targeted therapies called BH3-mimetics...

In the present study, surface functionalized mannan sulphate silver nanoparticles (MS-AgNPs) were prepared and assessed for their wound healing potential. 20nm sized, spherical MS-AgNPs were prepared by one pot synthesis approach wherein the sulphated polysaccharide mannan sulphate (MS) played dual role of reducing as well as capping agent. The crystalline MS-AgNPs exhibited surface plasmon resonance centered at 400nm along with -32.40mV zeta potential. These stable MS-AgNPs showed enhanced cytocompatibility, targeting potential and cellular uptake in murine macrophages, human skin fibroblasts and human keratinocytes as compared to citrate reduced silver nanoparticles (C-AgNPs)...

Primary immunodeficiencies (PIDs) form a large and heterogeneous group of mainly rare disorders that affect the immune system. T-cell deficiencies account for about one-tenth of PIDs, most of them being monogenic. Apart from genetic and clinical information, lots of other data are available for PID proteins and genes, including functions and interactions. Thus, it is possible to perform systems biology studies on the effects of PIDs on T-cell physiology and response. To achieve this, we reconstructed a T-cell network model based on literature mining and TPPIN, a previously published core T-cell network, and performed semi-quantitative dynamic network simulations on both normal and T-cell PID failure modes...

Management and prognosis of disease requires the accurate determination of specific biomarkers indicative of normal or disease-related biological processes or responses to therapy. Moreover since multiple determinations of biomarkers have demonstrated to provide more accurate information than individual determinations to assist the clinician in prognosis and diagnosis, the detection of several clinical biomarkers by using the same analytical device hold enormous potential for early detection and personalized therapy and will simplify the diagnosis providing more information in less time...

OBJECTIVE: To investigate differences in surgical approach and postoperative outcomes for patients with ulcerative colitis (UC) before and after the introduction of biologic therapy. BACKGROUND: Biologic use has dramatically increased since Food and Drug Administration approval of infliximab. Studies conflict as to the effect of these agents on surgical outcomes with some demonstrating worse surgical outcomes whereas others have found no difference. METHODS: We used an administrative, all-payer, all-age group database located in New York State...

Uveitis is a sight-threatening primary intraocular inflammation of various origins in mainly young and active patients. Due to the absence of biomarkers in most of the cases, the current treatment of noninfectious entities remains nonspecific, using corticosteroids, conventional immunosuppressors, and more recently biological agents. Identification of regulatory T cells in different models of autoimmune uveitis together with the evaluation of this important subpopulation in different entities paved the way for new therapeutic strategies, in addition to exclusive pharmaceutical approaches...

Intervertebral disc (IVD) degeneration is a significant contributor to low back pain. The IVD is a fibrocartilaginous joint that serves to transmit and dampen loads in the spine. The IVD consists of a proteoglycan-rich nucleus pulposus (NP) and a collagen-rich annulus fibrosis (AF) sandwiched by cartilaginous end-plates. Together with the adjacent vertebrae, the vertebrae-IVD structure forms a functional spine unit (FSU). These microstructures contain unique cell types as well as unique extracellular matrices...

Obstructive respiratory diseases like asthma and chronic obstructive pulmonary disease (COPD) are currently treated by inhaled anti-inflammatory and bronchodilator drugs. Despite the availability of multiple treatments, both diseases are growing public health concerns. The majority of asthma patients are well controlled on current inhaled therapies but a substantial number of patients with severe asthma are not. Asthma affects an estimated 300 million people worldwide and approximately 20 percent have a severe form of the disease...

Cardiac regenerative therapies aim to protect and repair the injured heart in patients with ischemic heart disease. By injecting stem cells or other biologicals that enhance angio- or vasculogenesis into the infarct border zone (IBZ), tissue perfusion is improved, and the myocardium can be protected from further damage. For maximum therapeutic effect, it is hypothesized that the regenerative substance is best delivered to the IBZ. This requires accurate injections and has led to the development of new injection techniques...

Purpose In addition to prospective trials for non-small-cell lung cancers (NSCLCs) that are driven by less common genomic alterations, registries provide complementary information on patient response to targeted therapies. Here, we present the results of an international registry of patients with RET-rearranged NSCLCs, providing the largest data set, to our knowledge, on outcomes of RET-directed therapy thus far. Methods A global, multicenter network of thoracic oncologists identified patients with pathologically confirmed NSCLC that harbored a RET rearrangement...

BACKGROUND: Brain metastases (BM) from colorectal cancer (CRC) are rare, but the incidence is suspected to rise as treatment of metastatic (m) CRC improves. The aim of this study was to identify possible biological and clinical characteristics at initial presentation of mCRC that could predict later risk of developing BM. Furthermore, we wished to estimate the incidence of BM in long-term surviving patients. MATERIAL AND METHODS: We conducted a retrospective study on a Danish multicenter cohort of patients with mCRC who received cetuximab and irinotecan (CetIri) as third-line treatment...

HIV-associated neurocognitive disorder (HAND) often complicates HIV infection despite combination antiretroviral therapy (ART) and may be influenced by host genomics. We performed a genome-wide association study (GWAS) of HAND in 1,050 CNS HIV Anti-Retroviral Therapy Effects Research (CHARTER) Study participants. All participants underwent standardized, comprehensive neurocognitive, and neuromedical assessments to determine if they had cognitive impairment as assessed by the Global Deficit Score (GDS), and individuals with comorbidities that could confound diagnosis of HAND were excluded...

PURPOSE: Chromosomal translocation of the Mixed Lineage Leukemia (MLL) locus generates fusion proteins that drive acute myeloid leukemia (AML) resulting in atypical histone methyltransferase activity and alterations in the epigenetic regulation of gene expression. Targeting histone regulators, such as Enhancer of Zeste Homologue 2 (EZH2), has shown promise in AML. Profiling differential protein expression following inhibition of epigenetic regulators in AML may help to identify novel targets for therapeutics...

Environmental medical syndromes comprise sick building syndrome (SBS), multiple chemical sensitivity (MCS)/idiopathic environmental intolerances (IEI), electromagnetic hypersensitivity, chronic fatigue syndrome (CFS), burnout, fibromyalgia, and the candida syndrome. There is also some overlap described in the literature. There is still no established knowledge of etiology, pathology, pathophysiology, diagnostics, therapy, prevention and prognosis. These syndromes are thought to result from a complex interaction of physical, chemical and/or (micro)biological environmental stresses, individual dispositions, psychological influencing factors, perceptual and processing processes, variants of somatization disorders, culturally or socially caused distress, or simply iatrogenic causation...

Soren K Thomsen, Anna L Gloyn
Type 2 diabetes is a global epidemic with major effects on healthcare expenditure and quality of life. Currently available treatments are inadequate for the prevention of comorbidities, yet progress towards new therapies remains slow. A major barrier is the insufficiency of traditional preclinical models for predicting drug efficacy and safety. Human genetics offers a complementary model to assess causal mechanisms for target validation. Genetic perturbations are 'experiments of nature' that provide a uniquely relevant window into the long-term effects of modulating specific targets...

As the basic unit of living organisms, each single cell has unique molecular signatures and functions. Our ability to uncover the transcriptional and epigenetic signature of single cells has been hampered by the lack of tools to explore this area of research. The advent of microfluidic single cell technology along with single cell genome-wide DNA amplification methods had greatly improved our understanding of the expression variation in single cells. Transcriptional expression profile by multiplex qPCR or genome-wide RNA sequencing has enabled us to examine genes expression in single cells in different tissues...
