Purpose: BRAF mutations are frequently found in several glioma subtypes, including pleomorphic xanthoastrocytoma (PXA) and ganglioglioma and much less commonly in glioblastoma. We sought to determine the activity of vemurafenib, a selective inhibitor of BRAF, in patients with gliomas that harbor this mutation.

Patients And Methods: The VE-BASKET study was an open-label, nonrandomized, multicohort study for BRAF-mutant nonmelanoma cancers. Read More

Social tipping points in animal societies.

Proc Biol Sci 2018 Sep 19;285(1887). Epub 2018 Sep 19.

Santa Fe Institute, Santa Fe, NM 87501, USA.

Animal social groups are complex systems that are likely to exhibit tipping points-which are defined as drastic shifts in the dynamics of systems that arise from small changes in environmental conditions-yet this concept has not been carefully applied to these systems. Here, we summarize the concepts behind tipping points and describe instances in which they are likely to occur in animal societies. We also offer ways in which the study of social tipping points can open up new lines of inquiry in behavioural ecology and generate novel questions, methods, and approaches in animal behaviour and other fields, including community and ecosystem ecology.

High-energy brain dynamics during anesthesia-induced unconsciousness.

Netw Neurosci 2018 1;1(4):431-445. Epub 2017 Dec 1.

Department of Electrical and Systems Engineering, Washington University in St. Louis, St. Louis, MO, USA.

Characterizing anesthesia-induced alterations to brain network dynamics provides a powerful framework to understand the neural mechanisms of unconsciousness. To this end, increased attention has been directed at how anesthetic drugs alter the functional connectivity between brain regions as defined through neuroimaging. However, the effects of anesthesia on temporal dynamics at functional network scales is less well understood. Read More

Genentech, Inc., San Francisco, CA, USA.

Although programmed death-ligand 1-programmed death 1 (PD-L1-PD-1) inhibitors are broadly efficacious, improved outcomes have been observed in patients with high PD-L1 expression or high tumor mutational burden (TMB). PD-L1 testing is required for checkpoint inhibitor monotherapy in front-line non-small-cell lung cancer (NSCLC). However, obtaining adequate tumor tissue for molecular testing in patients with advanced disease can be challenging. Read More

How to Make a Mimic? Brood Parasitic Striped Cuckoo Eggs Match Host Shell Color but Not Pigment Concentrations.

J Chem Ecol 2018 Oct 6;44(10):940-946. Epub 2018 Jul 6.

Department of Animal Biology, School of Integrative Biology, University of Illinois at Urbana-Champaign, Champaign, IL, 61801, USA.

Hosts of avian brood parasites often use visual cues to reject foreign eggs, and several lineages of brood parasites have evolved mimetic eggshell coloration and patterning to circumvent host recognition. What is the mechanism of parasitic egg color mimicry at the chemical level? Mimetic egg coloration by Common Cuckoos Cuculus canorus is achieved by depositing similar concentrations of colorful pigments into their shells as their hosts. The mechanism of parasitic egg color mimicry at the chemical level in other lineages of brood parasites remains unexplored. Read More

GG protects the intestinal epithelium from radiation injury through release of lipoteichoic acid, macrophage activation and the migration of mesenchymal stem cells.

Gut 2018 Jun 22. Epub 2018 Jun 22.

Division of Gastroenterology, Washington University School of Medicine, Saint Louis, Missouri, USA.

Objective: GG (LGG), a probiotic, given by gavage is radioprotective of the mouse intestine. LGG-induced radioprotection is toll-like receptor 2 (TLR2) and cyclooxygenase-2 (COX-2)-dependent and is associated with the migration of COX-2+mesenchymal stem cells (MSCs) from the lamina propria of the villus to the lamina propria near the crypt epithelial stem cells. Our goals were to define the mechanism of LGG radioprotection including identification of the TLR2 agonist, and the mechanism of the MSC migration and to determine the safety and efficacy of this approach in models relevant to clinical radiation therapy.

Homophily, heterophily and the diversity of messages among decision-making individuals.

R Soc Open Sci 2018 Apr 11;5(4):180027. Epub 2018 Apr 11.

ENTEG, Faculty of Science and Engineering, University of Groningen, Nijenborgh 4, 9747 AG Groningen, The Netherlands.

To better understand the intriguing mechanisms behind cooperation among decision-making individuals, we study the simple yet appealing use of preplay communication or cheap talk in evolutionary games, when players are able to choose strategies based on whether an opponent sends the same message as they do. So when playing games, in addition to pure cooperation and defection, players have two new strategies in this setting: homophilic (respectively, heterophilic) cooperation which is to cooperate (respectively, defect) only with those who send the same message as they do. We reveal the intrinsic qualities of individuals playing the two strategies and show that under the replicator dynamics, homophilic cooperators engage in a battle of messages and will become dominated by whichever message is the most prevalent at the start, while populations of heterophilic cooperators exhibit a more harmonious behaviour, converging to a state of maximal diversity.

Kinship and Incest Avoidance Drive Patterns of Reproductive Skew in Cooperatively Breeding Birds.

Authors:
Christina Riehl

Am Nat 2017 12 2;190(6):774-785. Epub 2017 Nov 2.

Social animals vary in how reproduction is divided among group members, ranging from monopolization by a dominant pair (high skew) to equal sharing by cobreeders (low skew). Despite many theoretical models, the ecological and life-history factors that generate this variation are still debated. Here I analyze data from 83 species of cooperatively breeding birds, finding that kinship within the breeding group is a powerful predictor of reproductive sharing across species. Read More

Institut für Organische Chemie, Johannes Gutenberg-Universität Mainz, Duesbergweg 10-14, 55128 Mainz, Germany.

Electro-organic synthesis is a powerful technique for the sustainable preparation of compounds. However, many electrosynthetic reactions require complex equipment, are limited to a very narrow current density range, or have very long reaction times; some also involve nonselective transformations and bad scalability. The robust and selective synthesis of nonsymmetric biphenols and partially protected derivatives is established by anodic C-C cross-coupling. Read More

Neuroendocrine Modulation of IL-27 in Macrophages.

J Immunol 2017 10 23;199(7):2503-2514. Epub 2017 Aug 23.

Center for Thrombosis and Hemostasis, University Medical Center, Johannes Gutenberg University Mainz, 55131 Mainz, Germany;

Heterodimeric IL-27 (p28/EBV-induced gene 3) is an important member of the IL-6/IL-12 cytokine family. IL-27 is predominantly synthesized by mononuclear phagocytes and exerts immunoregulatory functional activities on lymphocytic and nonlymphocytic cells during infection, autoimmunity or neoplasms. There is a great body of evidence on the bidirectional interplay between the autonomic nervous system and immune responses during inflammatory disorders, but so far IL-27 has not been defined as a part of these multifaceted neuroendocrine networks.

Department of Mechanical and Materials Engineering, College of Engineering, University of Nebraska-Lincoln, Lincoln, NE, United States of America.

Despite the important role of mechanical signals in bone remodeling, relatively little is known about how fluid shear affects osteoblastic cell migration behavior. Here we demonstrated that MC3T3-E1 osteoblast migration could be activated by physiologically-relevant levels of fluid shear in a shear stress-dependent manner. Interestingly, shear-sensitive osteoblast migration behavior was prominent only during the initial period after the onset of the steady flow (for about 30 min), exhibiting shear stress-dependent migration speed, displacement, arrest coefficient, and motility coefficient.

Networks of conforming or nonconforming individuals tend to reach satisfactory decisions.

Proc Natl Acad Sci U S A 2016 11 31;113(46):12985-12990. Epub 2016 Oct 31.

Engineering and Technology Institute Groningen (ENTEG), Faculty of Mathematics and Natural Sciences, University of Groningen, 9747 AG Groningen, The Netherlands

Binary decisions of agents coupled in networks can often be classified into two types: "coordination," where an agent takes an action if enough neighbors are using that action, as in the spread of social norms, innovations, and viral epidemics, and "anticoordination," where too many neighbors taking a particular action causes an agent to take the opposite action, as in traffic congestion, crowd dispersion, and division of labor. Both of these cases can be modeled using linear-threshold-based dynamics, and a fundamental question is whether the individuals in such networks are likely to reach decisions with which they are satisfied. We show that, in the coordination case, and perhaps more surprisingly, also in the anticoordination case, the agents will indeed always tend to reach satisfactory decisions, that is, the network will almost surely reach an equilibrium state.

Division of Cardiology, Department of Medicine, Tulane University School of Medicine, Heart and Vascular Institute, 1430 Tulane Avenue, SL-48, New Orleans, LA, 70112, USA.

Background: Recent studies and meta-analysis have shown that complete revascularization (CR) compared with infarct-related artery revascularization (IRA) during percutaneous coronary intervention for ST-segment elevation myocardial infarction (STEMI) is associated with decreased mortality. However, it is unclear if CR versus IRA in STEMI during indexed hospitalization is associated with risk of contrast-induced acute kidney injury (CI-AKI).

Vemurafenib in patients with BRAF(V600E)-positive metastatic or unresectable papillary thyroid cancer refractory to radioactive iodine: a non-randomised, multicentre, open-label, phase 2 trial.

Lancet Oncol 2016 Sep 23;17(9):1272-82. Epub 2016 Jul 23.

Department of Medicine, Memorial Sloan Kettering Cancer Center, New York, NY, USA.

Background: About half of patients with papillary thyroid cancer have tumours with activating BRAF(V600E) mutations. Vemurafenib, an oncogenic BRAF kinase inhibitor approved for BRAF-positive melanoma, showed clinical benefit in three patients with BRAF(V600E)-positive papillary thyroid cancer in a phase 1 trial. We aimed to establish the activity of vemurafenib in patients with BRAF(V600E)-positive papillary thyroid cancer. Read More

Genomic analysis of 6,000-year-old cultivated grain illuminates the domestication history of barley.

Nat Genet 2016 09 18;48(9):1089-93. Epub 2016 Jul 18.

Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben, Seeland, Germany.

The cereal grass barley was domesticated about 10,000 years before the present in the Fertile Crescent and became a founder crop of Neolithic agriculture. Here we report the genome sequences of five 6,000-year-old barley grains excavated at a cave in the Judean Desert close to the Dead Sea. Comparison to whole-exome sequence data from a diversity panel of present-day barley accessions showed the close affinity of ancient samples to extant landraces from the Southern Levant and Egypt, consistent with a proposed origin of domesticated barley in the Upper Jordan Valley.

The western corn rootworm (WCR; Diabrotica virgifera virgifera LeConte) is a major pest of maize (Zea mays) that is well adapted to most crop management strategies. Breeding for tolerance is a promising alternative to combat WCR but is currently constrained by a lack of physiological understanding and phenotyping tools. We developed dynamic precision phenotyping approaches using C with positron emission tomography, root autoradiography, and radiometabolite flux analysis to understand maize tolerance to WCR Our results reveal that WCR attack induces specific patterns of lateral root growth that are associated with a shift in auxin biosynthesis from indole-3-pyruvic acid to indole-3-acetonitrile.

Development and validation of the brief esophageal dysphagia questionnaire.

Neurogastroenterol Motil 2016 Dec 5;28(12):1854-1860. Epub 2016 Jul 5.

Division of Gastroenterology & Hepatology, Northwestern University Feinberg School of Medicine, Chicago, IL, USA.

Background: Esophageal dysphagia is common in gastroenterology practice and has multiple etiologies. A complication for some patients with dysphagia is food impaction. A valid and reliable questionnaire to rapidly evaluate esophageal dysphagia and impaction symptoms can aid the gastroenterologist in gathering information to inform treatment approach and further evaluation, including endoscopy.

Evolution 2016 08 13;70(8):1760-9. Epub 2016 Jul 13.

Reproduction among members of social animal groups is often highly synchronized, but neither the selective advantages nor the proximate causes of synchrony are fully understood. Here I investigate the evolution of hatching synchrony in the Greater Ani (Crotophaga major), a communally nesting bird in which several unrelated females contribute eggs to a large, shared clutch. Hatching synchrony is variable, ranging from complete synchrony to moderate asynchrony, and is determined by the onset of incubation of the communal clutch. Read More

Examination Under Anesthesia for Posterior Wall Acetabular Fracture A Survey of the OTA Membership.

Bull Hosp Jt Dis (2013) 2016 Jun;74(2):124-9

Objectives: The purpose of this survey was to learn more about the indications, criteria, and methods surgeons use for performing examination under anesthesia (EUA) for "intermediate" sized posterior wall acetabular fractures (those involving 20% to 40% of the posterior wall) and to find what criteria are used to determine hip instability.

Methods: An 18 question survey was posted on the Ortho- paedic Trauma Association's website and was used to gather anonymous data from orthopaedic surgeons regarding their approach to the intermediate sized posterior wall fracture.

Results: Considerable variability existed among re- sponses to many of the questions asked. Read More

Enhanced lysis by bispecific oncolytic measles viruses simultaneously using HER2/neu or EpCAM as target receptors.

Mol Ther Oncolytics 2016 24;3:16003. Epub 2016 Feb 24.

Oncolytic Measles Viruses and Vaccine Vectors, Paul-Ehrlich-Institut , Langen, Germany.

To target oncolytic measles viruses (MV) to tumors, we exploit the binding specificity of designed ankyrin repeat proteins (DARPins). These DARPin-MVs have high tumor selectivity while maintaining excellent oncolytic potency. Stability, small size, and efficacy of DARPins allowed the generation of MVs simultaneously targeted to tumor marker HER2/neu and cancer stem cell (CSC) marker EpCAM. Read More
