Lagged response of tropical tropospheric temperature to solar ultraviolet variations on intraseasonal time scales
Authors: Hood L. L. 
Published: April 2016

AbstractCorrelative and regression analyses of daily ERA‐Interim reanalysis data for three separate solar maximum periods confirm the existence of a temperature response to short‐term (mainly ∼27 day) solar ultraviolet variations at tropical latitudes in both the lower stratosphere and troposphere. The response, which occurs at a phase lag of 6–10 days after the solar forcing peak, consists of a warming in the lower stratosphere, consistent with relative downwelling and a slowing of the mean meridional (Brewer‐Dobson) circulation, and a cooling in the troposphere. The midtropospheric cooling response is most significant in the tropical Pacific, especially under positive El Niño–Southern Oscillation conditions and may be related to a reduction in the number of Madden‐Julian oscillation events that propagate eastward into the central Pacific following peaks in short‐term solar forcing.
Expeditious and Convenient Synthesis of Polycyclic Difluoroboron Complexes of 2‐Oxoindoline‐3‐carboxamides by Tandem Reaction
Authors: Mo Shanyan , Xu Chuangchuang , Xu Jiaxi 
Published: April 2016

AbstractN‐Aryl‐2‐cyanodiazoacetamides produce polycyclic difluoroboron 2‐oxoindoline‐3‐carboxamide complexes (up to pentacyclic conjugative and fused systems) directly and expeditiously in the presence of boron trifluoride etherate. The boron trifluoride serves as both a catalyst and reactant in the tandem reaction. The tandem reaction includes the carbene aromatic CH insertion, hydrolysis of the cyano group into an amide group, and boronation of the two amide carbonyl groups. The synthetic method features the advantages of wide substrate scope and excellent chemoselectivity.magnified image

Published: April 2016

CaseA 57‐year‐old woman was transferred to our emergency department by ambulance with cardiopulmonary arrest caused by massive genital bleeding. Cardiopulmonary resuscitation, including massive transfusion, was carried out and the return of spontaneous circulation was achieved. A giant uterine tumor was considered the source of the bleeding. Although hysterectomy was necessary to achieve definitive hemostasis, the patient was unable to tolerate the operation because of hemodynamic instability, acidosis, and coagulopathy. Therefore, we undertook vaginal gauze packing and uterine artery embolization to attain temporary hemostasis, which resulted in hemodynamic stabilization. Abdominal hysterectomy for definitive hemostasis was carried out 10 h after the embolization.OutcomeThe patient made a good post‐surgical recovery without any complications.ConclusionIn treating hemorrhagic shock due to uterine leiomyoma, damage‐control resuscitation may be useful as a bridge prior to definitive hemostasis through hysterectomy.
Upregulation of inflammatory gene transcripts in periosteum of chronic migraineurs: Implications for extracranial origin of headache

Published: April 2016

ObjectiveChronic migraine (CM) is often associated with chronic tenderness of pericranial muscles. A distinct increase in muscle tenderness prior to onset of occipital headache that eventually progresses into a full‐blown migraine attack is common. This experience raises the possibility that some CM attacks originate outside the cranium. The objective of this study was to determine whether there are extracranial pathophysiologies in these headaches.MethodsWe biopsied and measured the expression of gene transcripts (mRNA) encoding proteins that play roles in immune and inflammatory responses in affected (ie, where the head hurts) calvarial periosteum of (1) patients whose CMs are associated with muscle tenderness and (2) patients with no history of headache.ResultsExpression of proinflammatory genes (eg, CCL8, TLR2) in the calvarial periosteum significantly increased in CM patients attesting to muscle tenderness, whereas expression of genes that suppress inflammation and immune cell differentiation (eg, IL10RA, CSF1R) decreased.InterpretationBecause the upregulated genes were linked to activation of white blood cells, production of cytokines, and inhibition of NF‐κB, and the downregulated genes were linked to prevention of macrophage activation and cell lysis, we suggest that the molecular environment surrounding periosteal pain fibers is inflamed and in turn activates trigeminovascular nociceptors that reach the affected periosteum through suture branches of intracranial meningeal nociceptors and/or somatic branches of the occipital nerve. This study provides the first set of evidence for localized extracranial pathophysiology in CM. Ann Neurol 2016;79:1000–1013
Recent advances in low‐toxic lead‐free metal halide perovskite materials for solar cell application

Published: April 2016

AbstractOrganic–inorganic hybrid metal halide perovskite materials have attracted exponentially increased attention for photovoltaic applications in the past few years, while the toxic lead component remains a big concern. Herein, we present the recent progress in researching lead‐free perovskite light absorbers for solar cell application, and the challenges in this field are also discussed, which may shed light on further investigation of low‐toxic, lead‐free and efficient perovskite solar cells for sustainable solar energy utilization. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.
Enhancing Well‐being of Homeless Individuals by Building Group Memberships
Authors: Johnstone Melissa , Jetten Jolanda , Dingle Genevieve A. , Parsell Cameron , Walter Zoe C. 
Published: April 2016

AbstractThere is growing recognition that social isolation and a lack of connectedness with social groups is one of the reasons why the subjective well‐being of homeless individuals is generally worse than the rest of the population. Past research amongst a range of populations suggests that the ability of an individual to take on new group memberships and/or their ability to maintain their memberships in meaningful groups is an important predictor of well‐being. In a mixed method study (N = 119), we examined the extent to which experiences at homeless accommodation form building blocks for the formation of multiple group memberships and to what extent this predicts positive well‐being. Qualitative analysis reveals the importance of feeling connected to the homeless service and supported by homeless accommodation staff. Linking these data to quantitative data from a second wave, we found that these experiences predicted well‐being. These findings provide further support for a strength‐based approach to homelessness, by providing insights into the ways that experiences at homeless accommodation can contribute to the development of multiple group memberships (i.e. social capital), and enhance the well‐being of those experiencing, and exiting, homelessness.

UV‐Enhanced Gas‐Solid Chlorination of Polyvinyl Chloride for Cleaner Production of Chlorinated Polyvinyl Chloride
Authors: Mao Ding , Yang Qianli , Zhang Xiong , Cheng Yi 
Published: April 2016

AbstractA vibrated‐bed reactor with an online UV‐Vis measuring system was established in order to reveal the dynamic process of UV‐enhanced chlorination of polyvinyl chloride (PVC). Influences of temperature, radiation time, and interval time of intermittent initiation on chlorination process as well as the overlapping enhanced effect of adjacent UV radiations were analyzed. By properly controlling the intermittent UV radiation, one can obtain a considerable steady reaction rate during the chlorination process to avoid the temperature runaway due to over‐accelerated reaction. Solid‐state nuclear magnetic resonance identified the microstructure change of chlorinated PVC particles. The whiteness value after thermal aging was determined to uncover the relationship between thermal stability and double‐bond content, where the results accorded with the related theory on polymer dehydrochlorination.
