Arousal from hibernation and reactivation of Eptesicus fuscus gammaherpesvirus (EfHV) in big brown bats.

Transbound Emerg Dis 2018 Dec 16. Epub 2018 Dec 16.

Department of Microbiology, Western College of Veterinary Microbiology, University of Saskatchewan, Saskatoon, Saskatchewan, Canada.

Many viruses that cause serious and often fatal disease in humans have spilled over from bats. Recent evidence suggests that stress may enhance virus shedding by bats increasing the possibility of transmission to other species. To understand the reasons for spillover it is therefore important to determine the molecular pathways that link stress to virus reactivation and shedding in bats. Read More

Adaptation of Rabensburg virus (RBGV) to vertebrate hosts by experimental evolution.

Virology 2018 Dec 13;528:30-36. Epub 2018 Dec 13.

The Arbovirus Laboratory, Wadsworth Center, New York State Department of Health, Slingerlands, NY, USA; Department of Biomedical Sciences, State University of New York at Albany School of Public Health, Albany, NY, USA.

Rabensburg virus (RBGV; Flaviviridae, Flavivirus) has been classified as both a novel flavivirus and a unique lineage of West Nile virus (WNV). RBGV and WNV share approximately 76% sequence homology, yet RBGV does not replicate to high viral titers within vertebrate cell lines at physiological temperatures and has not been naturally isolated from a vertebrate host. These unique genetic and biological characteristics make RBGV a viable tool to identify the genetic determinants of flavivirus infectivity and fitness in vertebrate hosts. Read More

When humans behave like monkeys: Feedback delays and extensive practice increase the efficiency of speeded decisions.

Cognition 2018 Dec 13;184:11-18. Epub 2018 Dec 13.

School of Psychology, University of Newcastle, Australia.

The study of non-human primates has been foundational in understanding the neural origins of human decision processes, yet the approach rests on the assumption that one can validly extrapolate from the animal to the human. In the context of decision making, this requires constancy across species in physiological and cognitive processes. The former cannot be experimentally validated and therefore remains assumed, and recent findings have called into question the latter: non-human primates become increasingly urgent as the time spent making a decision increases, but humans do not; from a normative perspective, monkeys are making closer-to-optimal decisions than humans.

Center for Neural Science, New York University, New York, NY 10003, USA; Shanghai Research Center for Brain Science and Brain-Inspired Intelligence, Shanghai 201210, China. Electronic address:

Computational modeling of brain mechanisms of cognition has largely focused on the cortex, but recent experiments have shown that higher-order nuclei of the thalamus participate in major cognitive functions and are implicated in psychiatric disorders. Here, we show that a pulvino-cortical circuit model, composed of the pulvinar and two cortical areas, captures several physiological and behavioral observations related to the macaque pulvinar. Effective connections between the two cortical areas are gated by the pulvinar, allowing the pulvinar to shift the operation regime of these areas during attentional processing and working memory and resolve conflict in decision making.

Emergence of omega-3 fatty acids in biomedical research.

Prostaglandins Leukot Essent Fatty Acids 2019 Jan 3;140:47-50. Epub 2018 Dec 3.

Laboratory of Molecular Signaling, National Institute of Alcohol Abuse and Alcoholism, National Institutes of Health, 5625 Fishers Lane, Room 3N07, Bethesda, MD 20892-9410, United States.

Shortly after the discovery that linoleic acid was an essential fatty acid in 1930, α-linolenic acid also was reported to prevent the fatty acid deficiency syndrome in animals. However, several prominent laboratories could not confirm the findings with α-linolenic acid, and as a result there was a loss of interest in omega-3 fatty acids in lipid research. Even the findings that a prostaglandin can be synthesized from eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is necessary for optimum retinal function generated only limited interest in omega-3 fatty acids.

Immune cells in the retina and choroid: Two different tissue environments that require different defenses and surveillance.

Prog Retin Eye Res 2018 Dec 12. Epub 2018 Dec 12.

Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia.

In the eye immune defenses must take place in a plethora of differing microenvironments ranging from the corneal and conjunctival epithelia facing the external environment to the pigmented connective tissue of the uveal tract containing smooth muscle, blood vessels and peripheral nerves to the innermost and highly protected neural retina. The extravascular environment of the neural retina, like the brain parenchyma, is stringently controlled to maintain conditions required for neural transmission. The unique physiological nature of the neural retina can be attributed to the blood retinal barriers (BRB) of the retinal vasculature and the retinal pigment epithelium, which both tightly regulate the transport of small molecules and restrict passage of cells and macromolecules from the circulation into the retina in a similar fashion to the blood brain barrier (BBB).

Our knowledge on the bioavailability and actions of insulin-like growth factor-1 (IGF-1) has markedly expanded in recent years as novel mechanisms were discovered on IGF binding proteins (IGFBPs) and their ability to release IGF-1. The new discoveries allowed a better understanding of the endogenous physiological actions of IGF-1 and also its applicability in therapeutics. The focus of the present review is to summarize novel findings on the neuronal, neuroendocrine and neuroplastic actions of IGF-1 in the adult brain. Read More

Receptor- and store-operated mechanisms of calcium entry during the nanosecond electric pulse-induced cellular response.

Biochim Biophys Acta Biomembr 2018 Dec 12. Epub 2018 Dec 12.

Air Force Research Laboratory, 711th Human Performance Wing, Airman Systems Directorate, Bioeffects Division, Radio Frequency Bioeffects Branch, 4141 Petroleum Road, JBSA Fort Sam Houston, TX 78234, USA.

Nanosecond electric pulses have been shown to open nanopores in the cell plasma membrane by fluorescent imaging of calcium uptake and fluorescent dyes, including propidium (Pr) iodide and YO-PRO-1 (YP). Recently, we demonstrated that nsEPs also induce the phosphoinositide intracellular signaling cascade by phosphatidylinositol‑4,5‑bisphosphate (PIP) depletion resulting in physiological responses similar to those observed following stimulation of G-coupled receptors. In this paper, we explore the role of receptor- and store-operated calcium entry (ROCE/SOCE) mechanisms in the observed response of cells to nsEP. Read More

Adipose Tissue Dendritic Cells in Steady-State.

Immunology 2018 Dec 15. Epub 2018 Dec 15.

William Harvey Research Institute, Barts and the London, Queen Mary University of London, London, UK.

Healthy white adipose tissue (WAT) participates in regulating systemic metabolism, whilst dysfunctional WAT plays a prominent role in the development of obesity-associated comorbidities. Tissue resident immune cells are important for maintaining WAT homeostasis, including conventional dendritic cells (cDCs) which are critical in the initiation and regulation of adaptive immune responses. Due to phenotypic overlap with other myeloid cells, the distinct contribution of WAT cDCs has been poorly understood. Read More

Alternative transcript imbalance underlying breast cancer susceptibility in a family carrying PALB2 c.3201+5G>T.

Breast Cancer Res Treat 2018 Dec 14. Epub 2018 Dec 14.

Oncogenetics Group, Vall d'Hebron Institute of Oncology, VHIO, 08035, Barcelona, Spain.

Purpose: Disruption of splicing motifs by genetic variants can affect the correct generation of mature mRNA molecules leading to aberrant transcripts. In some cases, variants may alter the physiological transcription profile composed of several transcripts, and an accurate in vitro evaluation is crucial to establish their pathogenicity. In this study, we have characterized a novel PALB2 variant c. Read More

Existence and features of the myodural bridge in Gallus domesticus: indication of its important physiological function.

Anat Sci Int 2018 Dec 14. Epub 2018 Dec 14.

Department of Anatomy, College of Basic Medicine, Dalian Medical University, Dalian, China.

The myodural bridge (MDB) is a dense connective tissue that connects muscles with the cervical spinal dura mater via the posterior atlanto-occipital and atlato-axial interspaces. To date, the physiological function of the MDB has not been fully elucidated. Recent studies have identified the presence of the MDB in mammals, but very little information is available on the existence of the MDB in avifauna. Read More

Effectiveness of cognitive-behavioural therapy: a protocol for an overview of systematic reviews and meta-analyses.

BMJ Open 2018 Dec 14;8(12):e025761. Epub 2018 Dec 14.

Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences, University of Oxford, Oxford, UK.

Introduction: Cognitive-behavioural therapy (CBT) is a psychological therapy that has been used to improve patient well-being across multiple mental and physical health problems. Its effectiveness has been examined in thousands of randomised control trials that have been synthesised into hundreds of systematic reviews. The aim of this overview is to map, synthesise and assess the reliability of evidence generated from these systematic reviews of the effectiveness of CBT across all health conditions, patient groups and settings.
