The purpose of this article is to describe the process of civilizing Islamic values in educational activities in the formal education environment. In theory, formal education institutions are considered effective in cultivating Islamic values for character building for learning citizens. Professional practitioner activities combine constellations of values, goals, sanctions, knowledge and methods that are consistently manifested in the form of certain moral ideas. The operational forms as are expressed in everyday actions with a specified level of system and target. The study was carried out through observation and interviews with purposive participants and also snowballing method. All available information is analyzed qualitatively. The results of this study state that the civilizing of character values in formal education institutions becomes effective because psychologically students will be more obedient, fearful, and reluctant to teachers than parents or the general public. The main key is consistent in the application of rules, evaluation, reward and punishment in applying religious character, moderate, intelligent, independent and nationality which is a benchmark for the successful planting of Islamic values to shape the nation's character. Key words: Civilization, Education, Islamic Values, Character of the Nation.

An approach to develop a continuing professional development workshop for nurses to differentiate, delirium, dementia and depression among older adults
Authors: Elansari Hala , Johnson Jessie , Kelly Daniel Robert 
Published: April 2020

Delirium, dementia, and depression challenge nurses in acute care settings. They negatively impact older adult's health, well-being, and quality of life. Misdiagnosis of delirium, dementia, and depression is associated with higher mortality rate, functional decline, increased length of stay, higher admission and institutionalization rates, and higher health care expenditures. Nurses in acute care settings have a lack of knowledge about delirium, dementia, and depression. This lack of knowledge could have implication as necessary referrals to physicians is needed in order to ensure initiating of appropriate treatment. Continuing professional development is necessary to keep nurses abreast of the rapid changes in knowledge and technology needed to provide safe and high quality services. Providing an opportunity to participate in continuing professional development on this particular subject would go a long way to facilitate knowledge translation. As a result nurses will be equipped with the adequate knowledge and skills to meet the overall goal of providing quality care for older adults in different care settings.

Published: April 2020

LIN28A is a conserved RNA‐binding protein that inhibits the biogenesis of let‐7 microRNAs, thus promoting cancer progression. However, mechanisms underlying the activation of the LIN28A‐let‐7 signaling pathway remain poorly understood. Here, we show that LIN28A is SUMOylated in vivo and in vitro at K15, which is increased by hypoxia but reduced by chemotherapy drugs such as Cisplatin and Paclitaxel. SUMOylation of LIN28A aggravates its inhibition of let‐7 maturation, resulting in a stark reduction in let‐7, which promotes cancer cell proliferation, migration, invasion, and tumor growth in vivo. Mechanistically, SUMOylation of LIN28A increases its binding affinity with the precursor let‐7 (pre‐let‐7), which subsequently enhances LIN28A‐mediated recruitment of terminal uridylyltransferase TUT4 and simultaneously blocks DICER processing of pre‐let‐7, thereby reducing mature let‐7 production. These effects are abolished in SUMOylation‐deficient mutant LIN28A‐K15R. In summary, these findings shed light on a novel mechanism by which SUMOylation could regulate the LIN28A‐let‐7 pathway in response to cellular stress in cancer cells.

AbstractObjectiveTo quantify peripheral nerve lesions in symptomatic and asymptomatic hereditary transthyretin amyloidosis with polyneuropathy (ATTRv‐PNP) by analyzing the magnetization transfer ratio (MTR) of the sciatic nerve, and to test its potential as a novel biomarker for macromolecular changes.MethodsTwenty‐five patients with symptomatic ATTRv‐PNP, 30 asymptomatic carriers of the mutant transthyretin gene (mutTTR), and 20 age‐/sex‐matched healthy controls prospectively underwent magnetization transfer contrast imaging at 3 Tesla. Two axial three‐dimensional gradient echo sequences with and without an off‐resonance saturation rapid frequency pulse were conducted at the right distal thigh. Sciatic nerve regions of interest were manually drawn on 10 consecutive axial slices in the images without off‐resonance saturation, and then transferred to the corresponding slices that were generated by the sequence with the off‐resonance saturation pulse. Subsequently, the MTR and cross‐sectional area (CSA) of the sciatic nerve were evaluated. Detailed neurologic and electrophysiologic examinations were conducted in all ATTRv‐PNP patients and mutTTR‐carriers.ResultsSciatic nerve MTR and CSA reliably differentiated between ATTRv‐PNP, mutTTR‐carriers, and controls. MTR was lower in ATTRv‐PNP (26.4 ± 0.7; P < 0.0001) and in mutTTR‐carriers (32.6 ± 0.8; P = 0.0005) versus controls (39.4 ± 2.1), and was also lower in ATTRv‐PNP versus mutTTR‐carriers (P = 0.0009). MTR correlated negatively with the NIS‐LL and positively with CMAPs and SNAPs. CSA was higher in ATTRv‐PNP (34.3 ± 1.7 mm3) versus mutTTR‐carriers (26.0 ± 1.1 mm3; P = 0.0005) and versus controls (20.4 ± 1.2 mm3; P < 0.0001). CSA was also higher in mutTTR‐carriers versus controls.InterpretationMTR is a novel imaging marker that can quantify macromolecular changes in ATTRv‐PNP and differentiate between symptomatic ATTRv‐PNP and asymptomatic mutTTR‐carriers and correlates with electrophysiology.
The Dichotomy of Gold‐catalyzed Interplay between Cyanamides and Ynamides: Controllable Switch from [2+2+2] to [4+2] Cycloaddition

Published: April 2020

AbstractThe gold‐catalyzed interplay between cyanamides and ynamides demonstrates condition‐dependent mechanistic dichotomy. [2+2+2] Cycloaddition proceeds under kinetically controlled conditions to give 2,4,6‐triaminopyrimidines (19 examples, up to 99%). Under thermodynamically controlled conditions, the reactivity switches from [2+2+2]‐ to [4+2] cycloaddition; the latter [4+2] reaction accomplishes 1,3‐diaminoisoquinolines (19 examples, up to 97%). The advantages of both methods include regioselectivity, mild reaction conditions (even for the thermodynamically controlled [4+2] reaction) and the possibility of introducing a variety of dialkyl, diaryl, and heterocyclic amino substituents into the target pyrimidine and isoquinoline cores. The reactions were conducted on gram scales and the versatility of the obtained products was demonstrated by post‐functionalizations.magnified image
Who Wins and Who Loses? Trader Returns and Risk Premiums in Agricultural Futures Markets
Authors: Moran Nicole M. , Irwin Scott H. , Garcia Philip 
Published: April 2020

AbstractThe rise of commodity index traders (CITs) in the early 2000s provides a natural experiment to identify whether passive holding of long agricultural futures positions earns a positive risk premium. We use nearly a decade of daily nonpublic position data for all large traders to compute trading profits in twelve agricultural futures markets. Despite increasing price trends in a majority of markets, CITs were the biggest losers during the sample period, experiencing losses in nine out of twelve markets and an aggregate loss of $6.9 billion. This is just the opposite of the prediction of the theory of normal backwardation.

Published: April 2020

AbstractCover crops (CC) are versatile and have multifunctional benefits in crop rotations. An understanding of the effect of tillage systems on cover crop (CC) residue decomposition and nitrogen (N) release is essential in cash crop production planning. We investigated the decomposition rate and N release from cereal rye (Secale cerealeL.) and hairy vetch (Vicia villosaRoth.) CC residue in no‐tillage (NT) and reduced‐tillage (RT) systems under corn (Zea maysL.)–soybean [Glycine max(L.) Merr.] rotations. Litterbags were placed in the soil in RT and on soil surface in NT after CC termination in April and collected weekly for 10 wk to measure residue and N retained. Tillage systems did not affect the decomposition rate constant (k) and accumulated N release for both CC. Hairy vetch residue decomposed faster (k = 0.3494) than cereal rye (k = 0.1955) and released a greater amount of N in the soil (hairy vetch vs. cereal rye = 60 vs. 28 kg ha−1), attributable to greater N concentration and narrow C/N ratio compared to cereal rye in 2017 and 2018. Hairy vetch rapidly released N in the soil within 2 wk of termination. Both cover crops had greater decomposition rate constant and accelerated mass loss in 2018 than in 2017, possibly due higher spring temperatures in 2018 than 2017. Hairy vetch CC after terminating greatly enhance N availability in the soil, therefore, alternate management practices like planting green for grain crop following hairy vetch CC might be needed to capture released N.

AbstractAimSurvival outcomes in elderly patients with pathological stages (pStages) II and III gastric cancer remain inadequately elucidated. We retrospectively analyzed outcomes of elderly and nonelderly patients who underwent curative gastrectomy for this cancer and considered clinical results of the Estimation of Physiologic Ability and Surgical Stress (E‐PASS) scoring system for prediction.MethodsAmong 1041 patients who underwent gastrectomy for pStages II and III gastric cancer between 2008 and 2013 consecutively, 898 patients were enrolled. Of these, 158 patients (17.6%) were elderly and 740 patients (82.4%) were nonelderly.ResultsDisease‐specific survival (DSS) in the elderly group with pStage III cancer was significantly worse than that in the same stage nonelderly group (P = .001), while there was no difference in DSS for pStage II cancer between the groups (P = .45). Overall survival (OS) was significantly worse in elderly patients for both pStages II and III. Elderly patients with pStage II cancer had larger survival gaps between OS and DSS compared with those with pStage III cancer. OS for elderly patients with comprehensive risk score (CRS) > 0.159 was significantly worse than that for elderly patients with CRS ≤ 0.159 in pStage II cancer.ConclusionsCompared with nonelderly patients, different characteristics were observed in the survival outcomes of elderly patients between pStages II and III gastric cancer. The survival gap between OS and DSS of elderly patients was larger in pStage II cancer than in pStage III cancer. The E‐PASS scoring system could be a relatively useful predictor in elderly patients.
Low relationship quality predicts scratch contagion during tense situations in orangutans (Pongo pygmaeus)

Published: April 2020

AbstractPrimates show various forms of behavioral contagion that are stronger between kin and friends. As a result, behavioral contagion is thought to promote group coordination, social cohesion, and possibly state matching. Aside from contagious yawning, little is known about the contagious effect of other behaviors. Scratching is commonly observed during arousal and as such may play a role within group dynamics. While the Bornean orangutan (Pongo pygmaeus) is commonly considered the least social great ape, orangutans do engage in social interactions. Therefore, their social organization makes them a suitable case for studying the social function of behavioral contagion. Through behavioral observations of captive orangutans, we recorded all yawn and scratch events together with the corresponding behavior of all bystander group‐members. As yawning was rarely observed, no conclusions could be drawn regarding this behavior. Scratching was contagious and occurred within 90 s after the triggering scratch. Specifically, orangutans showed increased scratch contagion when they had seen a weakly bonded individual scratch during tense contexts. When the orangutan had not seen the triggering scratch, the contagiousness of scratching was not affected by context or relationship quality. Our results indicate that behavioral contagion is not simply higher between individuals with stronger social relationships, but that the contagiousness of behaviors may vary based on the context and on social factors. We discuss these findings in light of an adaptive function that may reduce aggression.
meta‐Selective C−H Arylation of Fluoroarenes and Simple Arenes

Published: April 2020

AbstractFluorine is known to promote ortho‐C−H metalation. Based upon this reactivity, we employed an activated norbornene that traps the ortho‐palladation intermediate and is then relayed to the meta position, leading to meta‐selective C−H arylation of fluoroarenes. Deuterium experiment suggests that this meta‐arylation is initiated by ortho C−H activation and the catalytic cycle is terminated by C‐2 protonation. A dual‐ligand system is crucial for the observed high reactivity and site selectivity. Applying this approach to simple benzene or other arenes also affords arylation products with good yield and site selectivity.

Published: April 2020

AbstractWe report herein an unprecedented highly efficient Guerbet‐type reaction at room temperature (catalytic TON up to >6000). This β‐alkylation of secondary methyl carbinols with primary alcohols has significant advantage of delivering higher‐order secondary alcohols in an economical, redox‐neutral fashion. In addition, the first enantioselective Guerbet reaction has also been achieved using a commercially available chiral ruthenium complex to deliver secondary alcohols with moderate yield and up to 92 % ee. In both reactions, the use of a traceless ketone promoter proved to be beneficial for the catalytic efficiency.
