Full textAbstract:
The interleukin (IL) 17 family of cytokines has emerged to be critical for host defense as well as the pathogenesis of autoimmune and autoinflammatory disorders, and serves to link adaptive and innate responses. Recent studies have identified a new subset of T cells that selectively produce IL-17 (Th17 cells; Bettelli, E., T. Korn, and V.K. Kuchroo. 2007. Curr. Opin. Immunol. 19:652–657; Kolls, J.K., and A. Linden. 2004. Immunity. 21:467–476), but the regulation of IL-17 production by innate immune cells is less well understood. We report that in vitro stimulation with IL-23 induced IL-17 production by recombination activating gene (Rag) 2−/− splenocytes but not Rag2−/− common γ chain−/− splenocytes. We found that a major source of IL-17 was CD4+CD3−NK1.1−CD11b−Gr1−CD11c−B220− cells, a phenotype that corresponds to lymphoid tissue inducer–like cells (LTi-like cells), which constitutively expressed the IL-23 receptor, aryl hydrocarbon receptor, and CCR6. In vivo challenge with the yeast cell wall product zymosan rapidly induced IL-17 production in these cells. Genetic deletion of signal transducer and activator of transcription 3 reduced but did not abrogate IL-17 production in LTi-like cells. Thus, it appears that splenic LTi-like cells are a rapid source of IL-17 and IL-22, which might contribute to dynamic organization of secondary lymphoid organ structure or host defense.

Full textAbstract:
The aim of this study was to determine pepsin hydrolysis conditions to produce digested oat bran proteins with higher radical scavenging activities and separate and identify peptides. Isolated proteins were then digested with different concentrations of pepsin and incubation times. Hydrolysates produced with 1 : 30 enzyme substrate (E/S) ratio and 2 h possessed the highest peroxyl radical scavenging activity, 608 ± 17 µM TE/g (compared to 456–474 µM TE/g for other digests), and was therefore subsequently fractionated into eight fractions (F1–F8) by high performance liquid chromatography (HPLC). F1 and F2 had little activity because of their low protein contents. Activities of F3–F8 were 447–874 µM TE/g, 20–36%, and 10–14% in the peroxyl, superoxide anion, and hydroxyl radical tests, respectively. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to identify a total of fifty peptides that may have contributed to the activity of F3, a fraction that better scavenged radicals.

ABSTRACT We present a multiwavelength analysis of two highly magnified strong gravitationally lensed galaxies, CLASS B0712+472 and CLASS B1608+656, at redshifts 1.34 and 1.394, respectively, using new VLBI (very long baseline interferometry) and archival Hubble Space Telescope observations. We reconstruct the positions of the radio and optical emissions with their uncertainties using Monte Carlo sampling. We find that in CLASS B0712+472 the optical and radio emissions are co-spatial within 2 ± 5 mas (17 ± 42 pc at redshift of 1.34). But, in CLASS B1608+656, we reconstruct an optical–radio offset of 25 ± 16 mas (214 ± 137 pc at redshift of 1.394), among the smallest offsets measured for an AGN (active galactic nucleus) at such high redshift. The spectral features indicate that CLASS B1608+656 is a post-merger galaxy, which, in combination with the optical–VLBI offset reported here, makes CLASS B1608+656 a promising candidate for a high- z offset–AGN. Furthermore, the milliarcsecond angular resolution of the VLBI observations combined with the precise lens models allow us to spatially locate the radio emission at 0.05 mas precision (0.4 pc) in CLASS B0712+472, and 0.009 mas precision (0.08 pc) in CLASS B1608+656. The search for optical–radio offsets in high redshift galaxies will be eased by the upcoming synoptic all-sky surveys, including Extremely Large Telescope and Square Kilometre Array, which are expected to find ∼105 strongly lensed galaxies, opening an era of large strong lensing samples observed at high angular resolution.

Aim. The results presented, of subanalysis of the catheter ablation (CA) registry in atrial fibrillation (AF) with the patients properties, specifics of CA and treatment results, in Russia comparing to European countries.Material and methods. During 2012 to 2015, totally 3742 patients included to the registry, of those 477 in Russia. In 467 Russian patients (males 56,5%; mean age 58,5 y. o.) CA AF was done. During one year 392 patients were followed up. Minimum requirements to follow-up: routine ECG registration and non less than one contact after 12 months passed.Results. In Russian patients there were more common obesity (46,1% and 29,2%, p<0,001), hypertension heart disease (40,2% and 22,8%, p<0,0001), coronary heart disease (31,7% and 16,2%, p<0,0001), chronic heart failure (67,3% and 13,0%, p<0,0001). In Russia the patients more commonly underwent primary CA (83,5% in Russia and 77,6% in European countries, p<0,05), more rare in Russia the cryoballoon ablation was done (3% and 18%, p<0,05). Generally adverse events were reported more rare in Russia (10,5% and 16,6%, p=0,0007), including cardiovascular adverse events (2,6% and 5,2%, p<0,05). Tachiarrhythmias recurs were diagnosed more rare in Russia, including by the subsutaneous ECG monitors (17% and 1,6% in other countries, р<0,001). Within the year of follow-up, full absence of tachiarrhythmias recurs in Russia was found in 65,8% of patients, in other countries — in 74,7% (р=0,0003).Conclusion. In real clinical setting, high efficacy of CA AF was shown, resistant to antiarrhythmic therapy. In most of Russian patients there were cardiovascular comorbidities. There was lower rate of reported adverse events in Russian centers of interventional treatments.

Aim. To study capabilities of quantitative elastographic study to assess the elasticity of the uterine cervix in women with a fetal chromosomal abnormality in the first trimester of pregnancy.Methods. 230 pregnant women of high-risk group at 11-13.6 weeks of pregnancy (parietal-coccygeal length 45-84 mm) were included in this study. The first group consisted of 213 women without fetal pathology. The second group included 17 women, in whose fetuses different chromosomal abnormalities were detected. In ultrasound examination of pregnant women in the I trimester of pregnancy, in addition to standard methods of examination, quantitative cervical elastography was performed.Results. According to results of quantitative elastography in 14 (82.35%) out of 17 pregnant women (second group) one or another degree of the cervical tissue softening was found, and 3 (17.64%) pregnant women with fetal chromosomal pathology had stiff cervix (all 3 cases with Down syndrome). In the control group in 10 (4.7%) of 213 pregnant women relatively soft cervix was identified, and in 203 (95.3%) women cervical density was higher than the myometrial density. A statistically significant difference between the indices of SWE-Ratio in groups was revealed. Quantitative elastography, as a diagnostic test predicting the risk of miscarriage due to chromosomal abnormalities, has a high sensitivity (84.38%) and even higher specificity (95.26%) of negative predictive value 97.57%.Conclusion. Quantitative elastography reveals a significant decrease in the cervical elasticity (softening) in pregnant women with fetal chromosomal abnormality in the I trimester of pregnancy, which allows us to recommend this method of ultrasound examination as an additional marker for early diagnosis of miscarriage due to fetal chromosomal abnormality.

AbstractWe consider the following second order evolution equation modelling a nonlinear oscillator with damping$$\ddot{u} (t) + \gamma \dot u(t) + Au\left( t \right) = f\left( t \right),\,\,\,\,\,\,\,\,\,\,\,\,\,\left( {{\rm{SEE}}} \right)$$where A is a maximal monotone and α-inverse strongly monotone operator in a real Hilbert space H. With suitable assumptions on γ and f(t) we show that A−1(0) ≠ ∅, if and only if (SEE) has a bounded solution and in this case we provide approximation results for elements of A−1(0) by proving weak and strong convergence theorems for solutions to (SEE) showing that the limit belongs to A−1(0). As a discrete version of (SEE), we consider the following second order difference equation$${u_{n + 1}} - {u_n} - {\alpha _n}\left( {{u_n} - {u_{n - 1}}} \right) + {\lambda _n}A{u_{n + 1}\ni} f\left( t \right),$$where A is assumed to be only maximal monotone (possibly multivalued). By using the results in [Djafari Rouhani B., Khatibzadeh H., On the proximal point algorithm, J. Optim. Theory Appl., 2008, 137, 411–417], we prove ergodic, weak and strong convergence theorems for the sequence un, and show that the limit is the asymptotic center of un and belongs to A−1(0). This again shows that A−1(0) ≠ ∅ if and only if un is bounded. Also these results solve an open problem raised in [Alvarez F., Attouch H., An inertial proximal method for maximal monotone operators via dicretization of a nonlinear oscillator with damping, Set Valued Anal., 2001, 9, 3–11], namely the study of the convergence results for the inexact inertial proximal algorithm. Our paper is motivated by the previous results in [Djafari Rouhani B., Asymptotic behaviour of quasi-autonomous dissipative systems in Hilbert spaces, J. Math. Anal. Appl., 1990, 147, 465–476; Djafari Rouhani B., Asymptotic behaviour of almost nonexpansive sequences in a Hilbert space, J. Math. Anal. Appl., 1990, 151, 226–235; Djafari Rouhani B., Khatibzadeh H., Asymptotic behavior of bounded solutions to some second order evolution systems, Rocky Mountain J. Math., 2010, 40, 1289–1311; Djafari Rouhani B., Khatibzadeh H., A strong convergence theorem for solutions to a nonhomogeneous second order evolution equation, J. Math. Anal. Appl., 2010, 363, 648–654; Djafari Rouhani B., Khatibzadeh H., Asymptotic behavior of bounded solutions to a class of second order nonhomogeneous evolution equations, Nonlinear Anal., 2009, 70, 4369–4376; Djafari Rouhani B., Khatibzadeh H., On the proximal point algorithm, J. Optim. Theory Appl., 2008, 137, 411–417] and significantly improves upon the results of [Attouch H., Maingé P. E., Asymptotic behavior of second-order dissipative evolution equations combining potential with non-potential effects, ESAIM Control Optim. Calc. Var., 2011, 17(3), 836–857], and [Alvarez F., Attouch H., An inertial proximal method for maximal monotone operators via dicretization of a nonlinear oscillator with damping, Set Valued Anal., 2001, 9, 3–11].

Abstract Aims Transvenous lead extraction for cardiac implantable electronic devices (CIED) is of growing importance. Nevertheless, the optimal anaesthetic approach, general anaesthesia vs. deep sedation (DS), remains unresolved. We describe our tertiary centre experience of the feasibility and safety of DS. Methods and results Extraction procedures were performed in the electrophysiology (EP) laboratory by two experienced electrophysiologists. We used intravenous Fentanyl, Midazolam, and Propofol for DS. A stepwise approach with locking stylets, dilator sheaths, and mechanical sheaths via subclavian, femoral, or internal jugular venous access was utilized. Patient characteristics and procedural data were collected. Logistic regression models were used to identify parameters associated with sedation-related complications. Extraction of 476 leads (dwelling time/patient 88 ± 49 months, 30% ICD leads) was performed in 220 patients (64 ± 17 years, 80% male). Deep sedation was initiated with bolus administration of Fentanyl, Midazolam, and Propofol; mean doses 0.34 ± 0.12 μg/kg, 24.3 ± 6.8 μg/kg, and 0.26 ± 0.13 mg/kg, respectively. Deep sedation was maintained with continuous Propofol infusion (initial dose 3.7 ± 1.1 mg/kg/h; subsequently increased to 4.7 ± 1.2 mg/kg/h with 3.9 ± 2.6 adjustments) and boluses of Midazolam and Fentanyl as indicated. Sedation-related episodes of hypotension, requiring vasopressors, and hypoxia, requiring additional airway management, occurred in 25 (11.4%) and 5 (2.3%) patients, respectively. These were managed without adverse consequences. Five patients (2.3%) experienced major intraprocedural complications; there were no procedure-related deaths. All of our logistic regression models indicated intraprocedural support was associated with administration higher Fentanyl doses. Conclusion Transvenous lead extraction under DS in the EP laboratory is a safe procedure with high success rates when performed by experienced staff.

ObjectivesOsteoarthritis (OA) is a complex disease, but its genetic aetiology remains poorly characterised. To identify novel susceptibility loci for OA, we carried out a genome-wide association study (GWAS) in individuals from the largest UK-based OA collections to date.MethodsWe carried out a discovery GWAS in 5414 OA individuals with knee and/or hip total joint replacement (TJR) and 9939 population-based controls. We followed-up prioritised variants in OA subjects from the interim release of the UK Biobank resource (up to 12 658 cases and 50 898 controls) and our lead finding in operated OA subjects from the full release of UK Biobank (17 894 cases and 89 470 controls). We investigated its functional implications in methylation, gene expression and proteomics data in primary chondrocytes from 12 pairs of intact and degraded cartilage samples from patients undergoing TJR.ResultsWe detect a genome-wide significant association at rs10116772 with TJR (P=3.7×10−8; for allele A: OR (95% CI) 0.97 (0.96 to 0.98)), an intronic variant in GLIS3, which is expressed in cartilage. Variants in strong correlation with rs10116772 have been associated with elevated plasma glucose levels and diabetes.ConclusionsWe identify a novel susceptibility locus for OA that has been previously implicated in diabetes and glycaemic traits.

Background:Methotrexate (MTX) is the most common first-line disease-modified anti-rheumatic drugs in psoriatic arthritis (PsA), despite the controversies.Objectives:In this study, we aimed to determine the rate of withdrawal rate of MTX in PsA and reasons for discontinuing.Objectives:In this study, we aimed to determine the rate of withdrawal rate of MTX in PsA and reasons for discontinuing.Methods:A large prospective international multicenter PsA registry was used for this study. Data were collected either at enrolment, based on history, or prospectively if there was a follow up. We analyzed the frequency of MTX usage, discontinuation and the reason for discontinuation. The time on MTX was compared according to the reason of discontinuation (inefficacy vs side effects) using Kaplan-Meier and Cox regression analyses to identify risk factors for discontinuation.Results:At the time of analyses, 1670 patients had been recruited to the registry and 1359 PsA patients had used MTX during the course of the disease (81.3%). Within these, 942 (69.3%) were still on MTX at the time of analysis, and 417 (30.7%) patients have discontinued (Table). The most common reasons for withdrawal were side effects (219/417, 52.5%) and ineffectiveness (88/417, 21.1%). Other reasons included pregnancy, remission, self-decision (11.9% for all). For 60 patients (14.3%), the reason could not be identified. In patients who were still on MTX, the median duration of MTX therapy was 31 months (IQR=59) compared to 17 months (IQR=43) in the withdrawal group. The most common side effects were gastrointestinal symptoms (47%) and abnormal liver function tests (25%). There was a significant difference in survival plots (Log-rank p=0.026) with discontinuing due to side effects occurring earlier than inefficacy (Figure 1). In cox regression model, longer disease duration was found as an independent predictor of MTX discontinuation due to all reasons [Hazard Ratio (HR)=1.01, 95% Confidence interval (CI)=1.0-1.02; p=0.003].Conclusion:MTX is frequently used on PsA treatment, despite the controversies in the literature. One third of patients with PsA discontinue MTX, most commonly due to side effects or inefficacy. Patients discontinue MTX earlier in case of having side effects. Longer disease duration is linked to MTX discontinuation.Table.Demographics and disease characteristics of study groupsAll patientsn=1359Still on MTXn=942Withdrawal MTX any reasonn=417pAge, mean (SD)46.4 (13.4)46.1 (13.4)47.7 (14.0)0.038Male gender, n (%)523 (38.5)360 (38.2)163 (39.1)0.761Ever smoking, n (%)569/1258 (46.2)390/861 (45.3)179/397 (45.1)0.966Psoriasis duration (years), mean (SD)14.2 (11.7)14.0 (11.2)16.4 (12.7)0.003Polyarthritis, n (%)657/1343 (48.9)471/931 (50.6)186/412 (45.1)0.066Axial disease, n (%)388/1343 (28.9)267/931 (28.7)121/412 (29.4)0.797Nail involvement (ever), n (%)644 (47.8)435 (46.6)209 (50.5)0.191Swollen Joint Count, mean (SD)1.5 (2.6)1.4 (2.6)2.0 (3.2)<0.001Tender Joint Count, mean (SD)3.0 (4.4)3.5 (5.0)4.2 (5.4)<0.001HAQ, mean (SD)0.6 (0.6)0.7 (0.7)0.8 (0.7)0.035BASDAI,mean (SD)37 (22)39 (23)46 (25)0.001Disclosure of Interests:Dilek Solmaz: None declared, Umut Kalyoncu Consultant of: Abbvie, Amgen, Janssen, Lilly, Novartis, UCB, Ilaria Tinazzi: None declared, Ozun Bayindir: None declared, Ediz Dalkiliç: None declared, Atalay Dogru: None declared, Cem Özişler: None declared, Gezmiş Kimyon: None declared, Gozde Yildirim Cetin Speakers bureau: AbbVie, Novartis, Pfizer, Roche, UCB, MSD, Ahmet Omma: None declared, Emine Figen Tarhan: None declared, Levent Kiliç: None declared, Servet Akar: None declared, Sema Yilmaz: None declared, Meryem Can: None declared, Sule Yavuz: None declared, Orhan Küçükşahin: None declared, Sibel Bakirci: None declared, Sibel Aydin: None declared

Full textAbstract:
The origin of the term “culture wars” is controversial. It was in the United States, however, that the expression became popularized, through the publication of Culture Wars, by James Davison Hunter, in 1991. It was a description of the clash between two antagonistic world views, a conservative one, often associated with political right, and a progressive one, predominantly related to the left, but not only. Cultural war brings with it social and moral problems that concern, for example, sexuality, behavior, race, religiosity, etc., but which may also involve political and economic issues. From the point of view of language, it is asked: in view of these cultural clashes in society, would there be a rhetoric that is peculiar to it? Would it be possible to think of some regularities, even though this war has peculiar traits among countries and historical periods? To think about these issues, this work is based on the pronouncements made in the Chamber of Deputies of Brazil, during the vote on the admissibility of the impeachment of Dilma Rousseff, on April 17, 2016. With the help of concepts in Rhetoric and Discourse Analysis, the objective of the book is also to evaluate in which sense the arguments in the process of dismissing the former president contributed or not to the integrity of Parliament, considered the par excellence public space for deliberation of democratic societies.

Full textAbstract:
The aging population worldwide is growing very fast: 8.5% are aged 65 and over. This is expected to jump up to 17% by 2050, in Africa 4.5%, by 2030. The authors argue that the majority of elderly people depend on services provided by their families and religious institutions. Although the African culture encourages family members to respect and care for their elderly persons, this has not been the case due to economic challenges facing families. Many elderly men and women live in poverty. Women suffer more because of cultural beliefs and responsibilities to care for HIV AIDS orphaned grandchildren. The beliefs that associate elderly women with witchcraft lead to abuse and killing of innocent people. The authors highlight the challenges for religious institutions to give shelter and provide medical services. They struggle with limited funds to provide what elderly people need to protect their dignity. Elderly people need a lot of love and good care, and the lack of trained elderly care takers becomes a challenge.

Enantiomerically-enriched alkoxy stannanes such as 3 are versatile intermediates for synthesis. John R. Falck of UT Southwestern found (Angew. Chem. Int. Ed. 2008, 47, 6586) that the simple combination of Bu3 SnH and Et2Zn generated a reagent that added to aldehydes such as 1 under catalysis by the MIB amino alcohol introduced by Nugent (Chem. Commun. 1999, 1369) to give the adduct 3 in high ee. Gonzalo Blay and José R. Pedro of the Universitat de València showed (Chem. Commun. 2008, 4840) that it was possible to modulate the reactivity of the acidic 4, allowing catalyzed formation of the high ee adduct 5 to dominate. Xiaoming Feng of Sichuan University developed (J. Am. Chem. Soc. 2008, 130, 15770) a Ni catalyst for the intermolecular ene reaction of 6 with 7 to give 8 in high ee. Enantioselective allylation is a key transformation in current organic synthesis. Yoshito Kishi of Harvard University optimized (Organic Lett. 2008, 10, 3073) enantioselective Cr-mediated allylation, with a ligand that can be easily recovered and recycled. Michael J. Krische of UT Austin devised (J. Am. Chem. Soc. 2008, 130, 14891) a ligand-catalyst combination for effecting the enantioselective allylation of alcohols such as 12 . Brian M. Stoltz of Caltech developed (Angew. Chem. Int. Ed. 2008, 47, 6873) a protocol for the enantioselective allylation of the enol ether 15, leading to the construction of oxygenated quaternary centers. Adducts such as 11 and 17 are of interest, inter alia , as direct precursors, by elimination, of the corresponding alkynes. Simon Blakey of Emory University designed (Angew. Chem. Int. Ed. 2008, 47, 6825) a Ru catalyst that mediated enantioselective intramolecular C-H amination, converting the simple alcohol derivative 18 into the versatile secondary amine 19 in high ee. We established (J. Org. Chem. 2008, 73, 9334) a procedure, based on diazo transfer followed by Rh-mediated intermolecular N-H insertion, for aminating menthyl esters and separating the product diastereomers. The menthyl group, easily removed (TFA) from 21, served as a useful reporter of ee, by 1H NMR of the upfield methyl doublets. Wolfgang Kroutil of the University of Graz found (Adv. Synth. Cat. 2008, 350, 2761) that ω-transaminases could effect the reductive amination of methyl ketones such as 22 in high ee.

Disorazole C1 3, isolated from fermentation of the myxobacterium Sorangium cellulosum, shows antifungal and anticancer activity. Amir H. Hoveyda of Boston College applied (J. Am. Chem. Soc. 2014, 136, 16136) recent advances in alkene metathesis from his group to enable the efficient assembly of 2 and so of 3. The ester 1 was assembled from the alcohol 11 and the acid 18. The preparation of 11 began with the enantioselective addition of 5 to 4 to give 6 and then 7, as described by Kalesse (Angew. Chem. Int. Ed. 2010, 49, 1619). Leighton allylation led to 8, that was then coupled with 9 to give 10 with high Z selectivity. Iodination of 10 followed by deprotection then completed the assembly of 11. The starting material for the acid 18 was the allylic alcohol 13. As reported by Cramer (Angew. Chem. Int. Ed. 2008, 47, 6483), exposure of the racemic alcohol 12 to vinyl acetate in the presence of Amano lipase PS converted one enantiomer to the acetate, leaving 13. Methylation of the secondary alcohol followed by acid-mediated removal of the t-butyl ester led to the acid 14, that was converted to the corresponding acyl fluoride and coupled with serine Me ester 15 to give 16. After cyclization to the oxazole 17, cross metathesis with five equivalents of 4-bromo-1-butene gave the homoallylic bromide, that was readily eliminated with DBU to give, after saponification, the acid 18. The cross metathesis of the coupled ester 1, a polyene, with 9 proceeded with remarkable selectivity to give 2, again as the Z geometric isomer. On exposure to the Heck catalyst Pd [(o-tolyl)3P]2, 2 dimerized efficiently. The deprotection was not straightforward, but conditions (H2SiF6, CH3OH, 4°C, 72 h) were found that delivered 3 in 68% yield.

In the context of peptidyl ketone synthesis, Troels Skrydstrup of the University of Aarhus developed (J. Org. Chem. 2008, 73, 1088) the elegant SmI2-mediated conjugate addition of acyl oxazolidinones such as 1 to acceptors such as 2. Sadagopan Raghavan of the Indian Institute of Chemical Technology, Hyderabad reported (Tetrahedron Lett. 2008, 49, 1601) that the addition of a Pummerer intermediate, generated by exposure of 4 to TFAA, to the terminal alkene 5 and SnCl4 led to efficient C-C bond formation, to give the sulfide 6 as a single (unassigned) diastereomer. Pd-catalyzed carbonylation of aryl halides and triflates is a well-established process. Stephen L. Buchwald of MIT has now (J. Am. Chem. Soc. 2008, 130, 2754) extended this transformation to much less expensive tosylates and mesylates such as 7. β-Amino acids have often been prepared from α-amino acids by Arndt-Eistert homologation. Geoffrey W. Coates of Cornell University has devised (Angew. Chem. Int. Ed. 2008, 47, 3979) a more practical alternative, the direct Co-catalyzed carbonylation of an oxazoline 9 to the 2-oxazine-6-one 10. Eiji Shirakawa and Tamio Hayashi of Kyoto University also used (Chem. Lett . 2008, 37, 654) a Co catalyst to promote the coupling of aryl and alkenyl Grignard reagents with enol trifl ates such as 11. Alois Fürstner of the Max-Planck-Institut, Mülheim optimized (Chem. Commun. 2008, 2873) promoters for the Pd-catalyzed Stille-Migata coupling of iodo alkenes such as 14 with alkenyl stannanes such as 15 to give 16. It is particularly noteworthy that their system is fluoride free. The stereocontrolled construction of trisubstituted alkenes continues to be challenging. We described (J. Org. Chem. 2008, 73, 1605) the facile preparation of the diioide 18 from the inexpensive 2-butyn-1,4-diol 17 . Sequential coupling of 18 with an aryl Grignard followed by CH3 Li delivered 19. Brian S. J. Blagg of the University of Kansas established (Tetrahedron Lett . 2008, 49, 141) that Still-Genari homologation of 20 with 21 gave (E)- 22 with high geometric control. Biao Jiang of the Shangahi Institute of Organic Chemistry reported (Organic Lett. 2008, 10, 593) a convenient alternative protocol to give ( Z )-α- bromo unsaturated esters.

Susumu Saito of Nagoya University developed (Angew. Chem. Int. Ed. 2011, 50, 3006) Fe-catalyzed conditions, compatible with alkenes, for converting an alcohol 1 to the amine 2. Corey R. J. Stephenson of Boston University took advantage (Nature Chem. 2011, 3, 140) of photoredox catalysis to convert an alcohol 3 to the iodide 4. Jing-Mei Huang of the South China University of Technology condensed (J. Org. Chem. 2011, 76, 3511) the halide 5 with benzaldehyde and aqueous ammonia to give the imine 6. Young Hoon Jung of Sungkyunkwan University used (Tetrahedron Lett. 2011, 52, 1901) chlorosulfonyl isocyanate to convert a benzylic (or allylic) ether 7 into the urethane 8. David Crich of Centre de Recherche de Gif coupled (Org. Lett. 2011, 13, 2256) the isocyanate 9 with the acid 10 to give the amide 11. Tobias Ritter of Harvard University effected (J. Am. Chem. Soc. 2011, 133, 1760) α-hydroxylation of the acidic ketone 12 by exposure to O2 in the presence of a Pd catalyst. Gowravaram Sabitha of the Indian Institute of Chemical Technology, Hyderabad, activated (Org. Lett. 2011, 13, 382) Pd(OH)2 by exposure to H2 , then used the activated catalyst to isomerize the allylic alcohol 14 to the aldehyde 15 . Richard C. Hartley of the University of Glasgow combined (Tetrahedron Lett. 2011, 52, 3020) commercial Nysted reagent and Cp2 TiCl2 to methyl-enate the ester 16. The enol ether 17 is a versatile intermediate, giving, inter alia, the methyl ketone by hydrolysis, or the α-hydroxy ketone on exposure to peracid. The activation of alkynes continues to be an area of vigorous investigation. Lukas Hintermann of the Technische Universitä t München devised (J. Am. Chem. Soc. 2011, 133, 8138) a Ru catalyst for the hydration of 18 to the aldehyde 19. Issa Yavari of Tarbiat Modares University effected (Tetrahedron Lett. 2011, 52, 668) oxidation of 20 to the N-sulfonyl amidine 22. Craig A. Merlic of UCLA coupled (Org. Lett. 2011, 13, 2778) 24 with the vinyl boronate derived from 23 to give the silyl enol ether 25. Li-Biao Han of AIST Tsukuba prepared (Chem. Commun. 2011, 47, 2333) 28 by adding 27 to 26.

Catal. 2011, 353, 2511) and László Poppe of the Budapest University of Technology and Economics discussed (Adv. Synth. Catal. 2011, 353, 2481) continuous flow reactors for biotransformations. Gases are readily handled in a flow apparatus. S. Chandrasekhar of the Indian Institute of Chemical Technology, Hyderabad demonstrated (Tetrahedron Lett. 2011, 52, 3865) partial deuteration of 1 to 2, using D2O as the deuterium source. Peter H. Seeberger of the Max Planck Institute, Potsdam oxidized (Org. Lett. 2011, 13, 5008) 3 to 4 with singlet oxygen. Dong-Pyo Kim of Chungnam National University and Robert H. Grubbs of Caltech effected (Org. Lett. 2011, 13, 2398) ethenolysis of 5 to give 6 and 7. Takashi Takahashi of the Tokyo Institute of Technology showed (Chem. Commun. 2011, 47, 12661) that even phosgene could be handled in a flow system, using it to activate 8 for condensation with benzylamine to give 9. In the liquid phase, Stephen L. Buchwald of MIT prepared (Angew. Chem. Int. Ed. 2011, 50, 8900) 11 by the fluorination of 10. Jesús Alcázar of Janssen Pharmaceutical, Toledo, showed (Tetrahedron Lett. 2011, 52, 6058) that a nitrile 12 could be reduced in a flow system to the aldehyde 13. Mark York of CSIRO prepared (Tetrahedron Lett. 2011, 52, 6267) the furan 16 by condensation of 14 with 15. Floris P.J.T. Rutjes of Radboud University Nijmegen used (Org. Process Res. Dev. 2011, 15, 783) the careful controls of a flow reactor to optimize the exothermic combination of 17 with 18 to give 19. Professor Buchwald demonstrated (Angew. Chem. Int. Ed. 2011, 50, 10665) a flow protocol for the lithiation of 20 with in situ borylation and Pd-catalyzed coupling with 21 to give 22.

Full textAbstract:
A total of 65 Przeworsk culture features were discovered in the Żelazna Nowa cemetery. This number included a rectangular groove feature, urned cremations (6), alleged/damaged urned cremations (14), unurned cremations (14), alleged/fully or partly damaged unurned cremations (27), pits containing no bone material (4), undtermined cremations (2), pits containing no archeological material (1). All of the explored burials are cremations. However, a more detailed analysis encounters problems due to the state of preservation of the graves. Features 3, 19A and 19B, 30, 33, 37, 39 have been confidently identified as urned cremations. In many other features fragments of ceramic vessels were found, which may be remains of damaged urns: 18, 21, 23, 25, 31, 35, 44, 46, 47, 48, 49, 56, 57, and 58. Certain unurned cremations are 4, 6, 7, 8, 11–13, 15–17, 22, 24, 32, and 34. The interpretation of the remaining features is uncertain. Among the features uncovered in the cemetery were pits containing no bones: 5, 60, 61, 62, as well as pits containing no archaeological material at all: 55. The majority of unurned cremations contained pyre debris, while no such remains were observed in the following damaged unurned cremations: 15, 40–42, 45, 61, 62. There were a few cases of double burials identified. Three unurned cremations (6, 13, 15) and one urned cremation (39) contained bones of Infans I and an undetermined individual, while feature 19 contained two urns with individual burials: Infans II and an undetermined individual. Urned cremations, and one alleged unurned cremation (56), are distinguished by a higher standard of furnishing and a considerably larger amount of bone remains. This can be given two interpretations: a higher status of those buried there, or different rituals used for urned and unurned cremations. In two graves the urn was covered with an upturned vessel (features 33 and 37). In one case, an apotropaic behaviour characteristic of the Przeworsk culture was recorded, involving driving sharp objects into the pit’s bottom: in grave 41 these were two spearheads.

La investigación se ocupa de la película interactiva de diseño interactivo Arthur 2.0 y Pericles Silveira. Examina, a partir de las pruebas de usabilidad, 6 momentos de interacción entre el interactor y el diseño interactivo de la película. Estos momentos se llaman Momentos Interactores (MI) y para comprobar si la interfaz película lleva a cabo de manera eficiente las tareas para las que fue diseñado: para hacer el plano de la película, en estos tiempos, ser lo más neutral posible y que las decisiones y las decisiones de la película provienen de los deseos del interactor y no la interfaz. La recolección de datos enfoca el uso de una combinación de métodos y técnicas - es decir, la observación y cuestionarios en un entorno con el público objetivo: los jóvenes de 12 a 17 años y adultos de 18 a 27 años y también con los espectadores de 28 a 37 años; 38-47 años y 48-68 años. En un sistema de interacción, ¿quién tiene el control? ¿Es el interactor? ¿El diseñador? ¿O el sistema? ¿Qué es un buen diseño interactivo y lo que es un mal diseño de interacción? Son algunas de las consideraciones que el trabajo es a partir de ese estudio.http://dx.doi.org/10.4995/ANIAV.2017.5758
