An update on Drug Repurposing: Re-written saga of the drug's fate.

Biomed Pharmacother 2018 Dec 12;110:700-716. Epub 2018 Dec 12.

Pharamacological Modelling and Simulation Centre, M.S.Ramaiah University of Applied Sciences, Bangalore, Karnataka, India; Department of Pharmacy Practice, Faculty of Pharmacy, M.S.Ramaiah University of Applied Sciences, Bangalore, Karnataka, India.

Drug repurposing is an unconventional drug discovery approach to explore new therapeutic benefits of existing, shelved and the drugs in clinical trials. This approach is currently emerging to overcome the bottleneck constraints faced during traditional drug discovery in grounds of financial support, timeline and resources. In this direction, several efforts were made for the construction of stratagems based on bioinformatics and computational tools to intensify the repurposing process off-late. Read More

Networks of problems: social, psychological, and genetic influences on health.

Curr Opin Psychol 2018 Nov 30;27:88-92. Epub 2018 Nov 30.

Department of Sociology, Stanford University, United States.

An emerging idea in psychopathology conceives of disorders as networks of mutually-reinforcing symptoms that constitute the disorder rather than simply reflect it. This is similar to how social scientists already view socioeconomic status, and has affinities to how physical health problems compound in later life. Social, psychological, and physical conditions might therefore be thought of as networks of problems with 'causal bridges' that span different levels and bring low SES, mental health challenges, and physical health problems into pervasive relationships with one another.

The influence of the OPRM1 (A118G) polymorphism on behavioral and neural correlates of aggression in healthy males.

Neuropharmacology 2018 Dec 12. Epub 2018 Dec 12.

Department of Psychiatry, Psychotherapy and Psychosomatics, Faculty of Medicine, RWTH Aachen University, 52074, Aachen, Germany; JARA Institute Brain Structure Function Relationship Institute for Neuroscience and Medicine (INM 10), Forschungszentrum Jülich, 52425 Jülich, Germany.

Current models of aggression suggest that in addition to personality traits and environmental factors, biological vulnerability associated with genetics substantially impacts aggressive behavior. In a functional imaging study, we investigated the influence of the single nucleotide polymorphism of the mu 1 subtype opioid receptor gene (OPRM1), implicated in sociability, on correlates of trait and state aggression to delineate the function of these influences in aggression. A key aim was further to differentiate different aspects of aggressive reactions - namely, the reaction to provocation and the decision to punish an opponent. Read More

Underestimated ecosystem carbon turnover time and sequestration under the steady state assumption: a perspective from long-term data assimilation.

Glob Chang Biol 2018 Dec 15. Epub 2018 Dec 15.

Key Laboratory of Tropical Forest Ecology, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Mengla, China.

It is critical to accurately estimate carbon (C) turnover time as it dominates the uncertainty in ecosystem C sinks and their response to future climate change. In the absence of direct observations of ecosystem C losses, C turnover times are commonly estimated under the steady-state assumption (SSA), which has been applied across a large range of temporal and spatial scales including many at which the validity of the assumption is likely to be violated. However the errors associated with improperly applying SSA to estimate C turnover time and its covariance with climate as well as ecosystem C sequestrations have yet to be fully quantified.

Foraging Performance, Prosociality, and Kin Presence Do Not Predict Lifetime Reproductive Success in Batek Hunter-Gatherers.

Hum Nat 2018 Dec 14. Epub 2018 Dec 14.

Department of Anthropology, Dartmouth College, Hanover, NH, 03755, USA.

Identifying the determinants of reproductive success in small-scale societies is critical for understanding how natural selection has shaped human evolution and behavior. The available evidence suggests that status-accruing behaviors such as hunting and prosociality are pathways to reproductive success, but social egalitarianism may diminish this pathway. Here we introduce a mixed longitudinal/cross-sectional dataset based on 45 years of research with the Batek, a population of egalitarian rain forest hunter-gatherers in Peninsular Malaysia, and use it to test the effects of four predictors of lifetime reproductive success: (i) foraging return rate, (ii) sharing proclivity, (iii) cooperative foraging tendency, and (iv) kin presence.

A National French consensus on gene lists for the diagnosis of myopathies using next-generation sequencing.

Eur J Hum Genet 2018 Dec 14. Epub 2018 Dec 14.

CHRU Montpellier, Laboratoire de Génétique moléculaire, Montpellier, France.

Next-generation sequencing (NGS) gene-panel-based analyses constitute diagnosis strategies which are adapted to the genetic heterogeneity within the field of myopathies, including more than 200 implicated genes to date. Nonetheless, important inter-laboratory diversity of gene panels exists at national and international levels, complicating the exchange of data and the visibility of the diagnostic offers available for referring neurologists. To address this issue, we here describe the initiative of the genetic diagnosis section of the French National Network for Rare Neuromuscular Diseases (Filière Nationale des Maladies Rares Neuromusculaires, FILNEMUS), which led to set up a consensual nationwide diagnostic strategy among the nine French genetic diagnosis laboratories using NGS for myopathies.

Transcriptome 3'end organization by PCF11 links alternative polyadenylation to formation and neuronal differentiation of neuroblastoma.

Nat Commun 2018 Dec 14;9(1):5331. Epub 2018 Dec 14.

Posttranscriptional Gene Regulation, Cancer Research and Experimental Haemostasis, University Medical Centre Mainz, Mainz, 55131, Germany.

Diversification at the transcriptome 3'end is an important and evolutionarily conserved layer of gene regulation associated with differentiation and dedifferentiation processes. Here, we identify extensive transcriptome 3'end-alterations in neuroblastoma, a tumour entity with a paucity of recurrent somatic mutations and an unusually high frequency of spontaneous regression. Utilising extensive RNAi-screening we reveal the landscape and drivers of transcriptome 3'end-diversification, discovering PCF11 as critical regulator, directing alternative polyadenylation (APA) of hundreds of transcripts including a differentiation RNA-operon.

Electrical and Computer Engineering Department, UC Santa Barbara, Santa Barbara, CA, 93106-9560, USA.

Spiking neural networks, the most realistic artificial representation of biological nervous systems, are promising due to their inherent local training rules that enable low-overhead online learning, and energy-efficient information encoding. Their downside is more demanding functionality of the artificial synapses, notably including spike-timing-dependent plasticity, which makes their compact efficient hardware implementation challenging with conventional device technologies. Recent work showed that memristors are excellent candidates for artificial synapses, although reports of even simple neuromorphic systems are still very rare. Read More

Templated synthesis of cubic crystalline single networks having large open-space lattices by polymer cubosomes.

Nat Commun 2018 Dec 14;9(1):5327. Epub 2018 Dec 14.

Department of Chemistry, Seoul National University, Seoul, 08826, South Korea.

The synthesis of biophotonic crystals of insects, cubic crystalline single networks of chitin having large open-space lattices, requires the selective diffusion of monomers into only one of two non-intersecting water-channel networks embedded within the template, ordered smooth endoplasmic reticulum (OSER). Here we show that the topology of the circumferential bilayer of polymer cubosomes (PCs)-polymeric analogues to lipid cubic membranes and complex biological membranes-differentiate between two non-intersecting pore networks embedded in the cubic mesophase by sealing one network at the interface. Consequently, single networks having large lattice parameters (>240 nm) are synthesized by cross-linking of inorganic precursors within the open network of the PCs. Read More

Objective: To evaluate the patient pathways and associated health outcomes, resource use and corresponding costs attributable to managing unhealed surgical wounds in clinical practice, from initial presentation in the community in the UK.

Methods: This was a retrospective cohort analysis of the records of 707 patients in The Health Improvement Network (THIN) database whose wound failed to heal within 4 weeks of their surgery. Patients' characteristics, wound-related health outcomes and healthcare resource use were quantified, and the total National Health Service (NHS) cost of patient management was estimated at 2015/2016 prices.

Ten-year trends in traumatic brain injury: a retrospective cohort study of California emergency department and hospital revisits and readmissions.

BMJ Open 2018 Dec 14;8(12):e022297. Epub 2018 Dec 14.

Department of Neurological Surgery, University of California, San Francisco, San Francisco, California, USA.

Objective: To describe visits and visit rates of adults presenting to emergency departments (EDs) with a diagnosis of traumatic brain injury (TBI). TBI is a major cause of death and disability in the USA; yet, current literature is limited because few studies examine longer-term ED revisits and hospital readmission patterns of TBI patients across a broad spectrum of injury severity, which can help inform potential unmet healthcare needs.

Design: We performed a retrospective cohort study. Read More

Indigenous health worker support for patients with poorly controlled type 2 diabetes: study protocol for a cluster randomised controlled trial of the Mana Tū programme.

BMJ Open 2018 Dec 14;8(12):e019572. Epub 2018 Dec 14.

Te Kupenga Hauora Māori, University of Auckland, Auckland, New Zealand.

Introduction: Type 2 diabetes mellitus (T2DM) and its complications are more common among Māori and Pacific people compared with other ethnic groups in New Zealand. Comprehensive and sustained approaches that address social determinants of health are required to address this condition, including culturally specific interventions. Currently, New Zealand has no comprehensive T2DM management programme for Māori or Pacific people. Read More

Phase-dependent suppression of beta oscillations in Parkinson's disease patients.

J Neurosci 2018 Dec 14. Epub 2018 Dec 14.

MRC Brain Network Dynamics Unit, Department of Pharmacology, University of Oxford, Oxford OX1 3TH, United Kingdom

Synchronized oscillations within and between brain areas facilitate normal processing, but are often amplified in disease. A prominent example is the abnormally sustained beta-frequency (∼20Hz) oscillations recorded from the cortex and subthalamic nucleus of Parkinson's disease patients. Computational modelling suggests that the amplitude of such oscillations could be modulated by applying stimulation at a specific phase. Read More

Genetic variation at the glycosaminoglycan metabolism pathway contributes to the risk of psoriatic arthritis but not psoriasis.

Ann Rheum Dis 2018 Dec 14. Epub 2018 Dec 14.

Rheumatology Research Group, Vall d'Hebron Research Institute, Barcelona, Spain

Objective: Psoriatic arthritis (PsA) is a chronic inflammatory arthritis affecting up to 30% of patients with psoriasis (Ps). To date, most of the known risk loci for PsA are shared with Ps, and identifying disease-specific variation has proven very challenging. The objective of the present study was to identify genetic variation specific for PsA. Read More

Generation and molecular recognition of melanoma-associated antigen-specific human γδ T cells.

Sci Immunol 2018 Dec;3(30)

Sunnybrook Research Institute, Toronto, ON, Canada.

Antigen recognition by T cells bearing αβ T cell receptors (TCRs) is restricted by major histocompatibility complex (MHC). However, how antigens are recognized by T cells bearing γδ TCRs remains unclear. Although γδ T cells can recognize nonclassical MHC, it is generally thought that recognition of antigens is not MHC restricted. Read More

Development of an Electronic Data Collection System to Support a Large-Scale HIV Behavioral Intervention Trial: Protocol for an Electronic Data Collection System.

JMIR Res Protoc 2018 Dec 14;7(12):e10777. Epub 2018 Dec 14.

Department of Psychiatry and Biobehavioral Sciences, University of California, Los Angeles, Los Angeles, CA, United States.

Background: Advancing technology has increased functionality and permitted more complex study designs for behavioral interventions. Investigators need to keep pace with these technological advances for electronic data capture (EDC) systems to be appropriately executed and utilized at full capacity in research settings. Mobile technology allows EDC systems to collect near real-time data from study participants, deliver intervention directly to participants' mobile devices, monitor staff activity, and facilitate near real-time decision making during study implementation.
