GPS/CSS radio sources and their relation to other AGN
Authors: Sadler E. M. 
Published: February 2016

AbstractWe are entering a new era of sensitive, large‐area and multi‐frequency radio surveys that will allow us to identify Gigahertz‐Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) radio sources over a wide range in radio luminosity and study them within the context of the overall radio‐source populations to which they belong. “Classical” GPS/CSS objects are extremely luminous radio sources with a compact double morphology, commonly thought to represent the earliest stages in the life cycle of powerful radio galaxies (e.g. O'Dea 1998). It is now becoming easier to identify GPS/CSS candidates with much lower radio luminosity – particularly in the nearby Universe. These less powerful objects, with typical 1.4 GHz radio luminosities of 1023 to 1025 W Hz–1, include peaked‐spectrum radio sources with a core‐jet morphology on parsec scales as well as high‐frequency GPS‐like peaked components embedded within lower‐frequency extended emission. In the latter case, the presence of a young GPS component may not be evident from low‐frequency data alone. Many radio galaxies in the local Universe have a compact (FR‐0) morphology, and appear to lack extended radio emission on kiloparsec scales. The relationship of these FR‐0 objects to the classical GPS/CSS radio sources remains unclear – some of them may represent short‐lived episodes of AGN activity that will not lead to an extended FR‐1 or FR‐2 radio galaxy. Future wide‐band radio surveys will shed more light on this – such surveys should ideally be coordinated to cover the full frequency range from 100 MHz to 100 GHz in order to sample all stages of GPS/CSS evolution in an unbiased way.

The Lockman Hole with LOFAR: Searching for GPS and CSS sources at low frequencies
Authors: Mahony E. K. , Morganti R. , Prandoni I. , van Bemmel I. 
Published: February 2016

AbstractThe Lockman Hole Project is a wide international collaboration aimed at exploiting the multi‐band extensive and deep information available for the Lockman Hole region, with the aim of better characterizing the physical and evolutionary properties of the various source populations detected in deep radio fields. Recent observations with the LOw‐Frequency ARray (LOFAR) extends the multi‐frequency radio information currently available for the Lockman Hole (from 350 MHz up to 15 GHz) down to 150 MHz, allowing us to explore a new radio spectral window for the faint radio source population. These LOFAR observations allow us to study the population of sources with spectral peaks at lower radio frequencies, providing insight into the evolution of GPS and CSS sources. In this general framework, I present preliminary results from 150 MHz LOFAR observations of the Lockman Hole field. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
The infrared properties of the GPS and CSS radio sources
Authors: O'Dea C.P. 
Published: February 2016

AbstractI review the results of three Spitzer studies of GHz‐Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) radio galaxies. The luminosity of the IR continuum and the high ionization lines confirm that some GPS/CSS can have central engines which are similar to those of the extended powerful radio sources. This is consistent with the hypothesis that some GPS/CSS can evolve to become the large‐scale sources. Warm H2 is common in the GPS/CSS sources consistent with feedback via jet‐ISM interaction. The GPS/CSS seem to have higher star formation rates than typical (2JY + 3CRR) radio sources. This should be confirmed with a larger sample. If compact sources interact with dense, clumpy star forming clouds and if the interaction with the dense medium sufficiently enhances the radio power, these star forming galaxies with enhanced radio emission will be selected for the current bright samples of GPS and CSS sources. This will increase the number of GPS and CSS sources which are observed to be forming stars. If radio sources have longer lives and/or star formation is more common in large radio galaxies, the need for a new population of star forming compact sources with enhanced radio emission is reduced.

AbstractWe address the impact of young radio jets on the ISM and star formation in a sample of radiatively efficient, highly obscured, radio AGN with look back times that place them near the peak of the galaxy and BH building era, z ∼ 1–3. By selecting systems with a high mid‐infrared (MIR) luminosity we aim to identify radiatively efficient (“quasar‐mode” or “radiative‐mode”) AGN in a peak fueling phase, and by selecting compact radio sources we favor young or re‐generated radio jets which are confined within the hosts. By selecting AGN which are very red through the optical‐MIR we favor highly obscured systems likely to have been recently merger‐triggered and still in the pre‐blow‐out phase of AGN feedback into the surrounding ISM. ALMA imaging at 345 GHz of 49 sources has revealed that they are accretion dominated, relative to star formation, with luminosities reaching 1014 L⊙. Extensive VLA imaging at 8–10 GHz in both A‐array and B‐array for 155 sources reveals that the majority of these powerful radio systems are compact on <2–5 kpc scales while some have resolved structures on 3–25 kpc scales, and a small number have giant radio lobes on hundreds of kpc scales. The majority of the GHz range radio SEDs are typical of optically thin synchrotron, however for the 34 sources with data at more than 2 frequencies, 40% are likely to be CSS, GPS, or HFP sources. VLBA imaging of 62 sources reveals varied morphologies, from unresolved sources to complex multicomponent 1–10 mas scale structures. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Explaining High Conjunction Fallacy Rates: The Probability Theory Plus Noise Account
Authors: Costello Fintan , Watts Paul 
Published: February 2016

AbstractThe conjunction fallacy occurs when people judge the conjunctive probability P(A ∧ B) to be greater than a constituent probability P(A), contrary to the norms of probability theory. This fallacy is a reliable, consistent and systematic part of people's probability judgements, attested in many studies over at least 40 years. For some events, these fallacies occur very frequently in people's judgements (at rates of 80% or more), while for other events, the fallacies are very rare (occurring at rates of 10% or less). This wide range of fallacy rates presents a challenge for current theories of the conjunction fallacy. We show how this wide range of observed fallacy rates can be explained by a simple model where people reason according to probability theory but are subject to random noise in the reasoning process.

Different Attentional Patterns for Regret and Disappointment: An Eye‐tracking Study
Authors: Bault Nadège , Wydoodt Pierre , Coricelli Giorgio 
Published: February 2016

AbstractThe unfavorable comparison between the obtained and expected outcomes of our choices may elicit disappointment. When the comparison is made with the outcome of alternative actions, emotions like regret can serve as a learning signal. Previous work showed that both anticipated disappointment and regret influence decisions. In addition, experienced regret is associated with higher emotional responses than disappointment. Yet it is not clear whether this amplification is due to additive effects of disappointment and regret when the outcomes of alternative actions are available, or whether it reflects the learning feature of regret signals. In this perspective, we used eye‐tracking to measure the visual pattern of information acquisition in a probabilistic lottery task. In the partial feedback condition, only the outcome of the chosen lottery was revealed, while in the complete feedback condition, participants could compare their outcome with that of the non‐chosen lottery, giving them the opportunity to experience regret. During the decision phase, visual patterns of information acquisition were consistent with the assessment of anticipated regret, in addition to a clear assessment of lotteries' expected values. During the feedback phase, subjective ratings and eye‐tracking results confirmed that participants compared their outcome with the outcome of the non‐chosen lottery in the complete feedback condition, particularly after a loss, and ignored the non‐realized outcome of the chosen option. Moreover, participants who made more visual saccades consistent with counterfactual comparisons during the feedback period anticipated regret more in their decisions. These results are consistent with the proposed adaptive function of regret. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.

AbstractPancreatic cancer patients are often resistant to chemotherapy treatment, which results in poor prognosis. The objective of this study was to delineate the mechanism by which miR‐21 induces drug resistance to 5‐fluorouracil (5‐FU) in human pancreatic cancer cells (PATU8988 and PANC‐1). We report that PATU8988 cells resistant to 5‐FU express high levels of miR‐21 in comparison to sensitive primary PATU8988 cells. Suppression of miR‐21 expression in 5‐Fu‐resistant PATU8988 cells can alleviate its 5‐FU resistance. Meanwhile, lentiviral vector‐mediated overexpression of miR‐21 not only conferred resistance to 5‐FU but also promoted proliferation, migration, and invasion of PATU8988 and PANC‐1 cells. The proresistance effects of miR‐21 were attributed to the attenuated expression of tumor suppressor genes, including PTEN and PDCD4. Overexpression of PTEN and PDCD4 antagonized miR‐21‐induced resistance to 5‐FU and migration activity. Our work demonstrates that miR‐21 can confer drug resistance to 5‐FU in pancreatic cancer cells by regulating the expression of tumor suppressor genes, as the target genes of miR‐21, PTEN and PDCD4 can rescue 5‐FU sensitivity and the phenotypic characteristics disrupted by miR‐21.

AbstractClear cell renal cell carcinoma (ccRCC) is the most prevalent adult kidney cancer. Prognostic markers are needed to guide patient management toward aggressive versus more conservative approaches, especially for small tumors ≤4 cm. miR‐194 was reported to be downregulated in several cancers and is involved in epithelial to mesenchymal transition. We evaluated miR‐194 as a prognostic marker in ccRCC. In a cohort of 234 patients with primary ccRCC, we correlated miR‐194 expression level with multiple clinicopathological features including disease‐free and overall survival, tumor size, clinical stage, and histological grade. Our results shows a stepwise decrease in miR‐194 expression from normal kidney to primary ccRCC (P = 0.0032) and a subsequent decrease from primary to metastatic lesions. Additionally, patients with higher miR‐194 expression has significantly longer disease‐free survival (P = 0.041) and overall survival (P = 0.031) compared to those with lower expression. In multivariate analysis, miR‐194‐positive tumors retain significance in disease‐free survival and overall survival, suggesting miR‐194 is an independent marker for good prognosis in ccRCC. Moreover, miR‐194 is a marker for good prognosis for patients with small renal masses (P = 0.014). These findings were validated on an independent data set from The Cancer Genome Atlas. We also compared miR‐194 expression between RCC subtypes. ccRCC had the highest levels, whereas chromophobe RCC and oncocytoma had comparable lower levels. Target prediction coupled with pathway analysis show that miR‐194 is predicted to target key molecules and pathways involved in RCC progression. miR‐194 represents a prognostic biomarker in ccRCC.

AbstractThe association between long‐term variation of postdiagnosis platelets and survival of pancreatic cancer (PC) has never been discussed by using dynamic survival analysis method. In this retrospective study, we analyzed 311 histologically confirmed PC patients identified from a mega population‐based electronic inpatients database from 2012 to 2013 in China. Counting process approach was applied to restructure the original survival data, the association between post‐diagnosis platelet count and overall survival (OS) of PC was evaluated by multiple failure‐time Cox proportional hazards model. After counting process adjustment, multiple failure‐time Cox proportional hazards model revealed that, regardless of the treatment modalities PC patients received, postdiagnosis thrombocytopenia was prominently associated with OS, compared with PC patients with normally ranged platelet count, the HRs ranged from 2.04 (95% CI: 1.14–3.67) to 10.82 (95% CI: 2.63–44.54), and this inverse association was robust based on further sensitivity analysis. On the contrary, the association between thrombocytosis and OS of PC tended to be inconclusive. Our findings suggested that postdiagnosis thrombocytopenia was associated with significantly compromised survival among PC patients from this large retrospective cohort. Underlying mechanisms behind this association should be further investigated.

AbstractMesenchymal stromal cells (MSCs) have been characterized as an important component of hematopoietic niche, which are capable of modulating the immune system through interaction with a wide range of immune cells. Marginal zone B cells, one main type of mature B lymphocytes, play a central role in eliciting antibody response against pathogens. However, how MSCs and its subpopulations regulate marginal zone B cells commitment is unknown yet. In this study, we assessed the contribution of Sca‐1+MSCs on marginal zone B cells commitment. Our results showed that Sca‐1+MSCs inhibit the commitment of marginal zone B lymphocytes. The inhibition was exerted through lowered Caspase‐3 expression. Furthermore, we found marginal zone B lymphocytes in spleen of Caspase‐3 knockout mice decreased and Caspase‐3 knockout Sca‐1+MSCs accounted for the MZB lymphocytes decrease. In conclusion, our investigation provided clues about Sca‐1+MSCs regulation on the commitment of marginal zone B cells through Caspase‐3 gene.

ObjectiveTo investigate the clinical outcomes influenced by distal extension of false lumen in acute type B aortic dissection (TBAD) patients following thoracic endovascular aortic repair (TEVAR). Methods: From April 2002 to January 2013, 264 TBAD patients treated with TEVAR were retrospectively enrolled. The IIIa group exhibited a distal false lumen above the diaphragm (n = 70), and the IIIb group exhibited a distal false lumen under the diaphragm (n = 194). The morphological characteristics and adverse events (30‐day and >30 days) were recorded and evaluated. Results: There were no significant differences between the two groups regarding the demographics, comorbidity profiles, or initial feature of computed tomography angiography. The incidence of true lumen compression and branch involvement were significantly increased in the IIIb group compared with the IIIa group (8.6% vs. 25.3%, respectively; 15.7% vs. 36.1%, respectively, both P < 0.05). The 30‐day mortality rate was 1.0% (2/194) in the IIIb group, whereas the IIIa group was zero. The incidence of early adverse events, the 5‐year cumulative freedom from adverse events, and the 5‐year cumulative freedom from all‐cause mortality rate were not significantly different between the IIIa and IIIb groups (2.9% vs. 6.7%, 81.4%, and 80.4%, and 95.7% vs. 93.8%, respectively, all P > 0.05). Log‐rank tests also indicated there was no significant difference. Conclusions: There was no significant difference between the IIIa and IIIb groups in the 5‐year morality and adverse aortic events following TEVAR. The distal extension of false lumen prior to TEVAR does not influence the long‐term morality and adverse aortic events in acute TBAD. © 2016 Wiley Periodicals, Inc.
