Abstract

Background
Endovascular rescue of failed infrarenal repair (EVAR) has emerged as an attractive option to stent graft explantation. The procedure, however, is underutilized due to limited devices accessibility and the challenges associated with their implantation in this patient population. The purpose of this study was to report our outcomes and discuss our approach to rescuing previously failed infrarenal endovascular aneurysm repairs (EVAR) with fenestrated/branched endografts (f/b-EVAR).

Methods
A retrospective analysis of prospectively collected data of consecutive patients with failed EVAR rescued with f/b-EVAR at our institution from November 2013 to March 2019 was conducted. The study primary end point was technical success; defined as the implantation of the device with no type I a/b or type III endoleak or conversion to open repair. Secondary endpoints included major adverse events (MAEs), graft patency and reintervention rates.

Results
During this time, 202 patients with complex aortic aneurysms were treated with f/b-EVAR. Of these, 19 patients (Male: 17, mean age 79 ± 7 years) underwent repair for failed EVAR. The median time from failed repair to f/b-EVAR was 48 (30, 60) months. Treatment failure was attributed to stent graft migration in 9 (47.4%) patients, disease progression in 5 (26.3%), short initial neck in 3 (15.8%) and unable to be determined in 2 (10.5%). Three patients were treated urgently with surgeon modified stent graft. Technical success was achieved in 18 patients (95%), including two who had undergone emergent repair for rupture. Seventy-two targeted vessels (97.3%) were successfully incorporated. Sixteen (84.2%) patients required a thoracoabdominal repair to achieve a durable seal. Major adverse events (MAEs) occurred in 3 patients (15.7%) including paralysis and death in one (5.3%), compartment syndrome and temporary dialysis in another and laparotomy with snorkeling of one renal and bypass of the other in the third patient. Median (IQR) hospital length of stay was 3 (2, 4) days. Late reintervention, primary target vessel patency and primary assisted patency rates were 5.3%, 98.6% and 100%, respectively.

Conclusion
Implantation of f/b-EVAR in patients with failed previous EVAR is a challenging undertaking that can be performed safely with a high technical success and low reintervention rates.
Deep-learning-based motion-correction algorithm in optical resolution photoacoustic microscopy
Authors: Chen Xingxing , Qi Weizhi , Xi Lei 
Published: October 2019

Abstract
In this study, we propose a deep-learning-based method to correct motion artifacts in optical resolution photoacoustic microscopy (OR-PAM). The method is a convolutional neural network that establishes an end-to-end map from input raw data with motion artifacts to output corrected images. First, we performed simulation studies to evaluate the feasibility and effectiveness of the proposed method. Second, we employed this method to process images of rat brain vessels with multiple motion artifacts to evaluate its performance for in vivo applications. The results demonstrate that this method works well for both large blood vessels and capillary networks. In comparison with traditional methods, the proposed method in this study can be easily modified to satisfy different scenarios of motion corrections in OR-PAM by revising the training sets.

Abstract
Chitooligosaccharides (COS) from squid pen produced using amylase, lipase and pepsin were characterized. COS produced by 8% (w/w) lipase (COS-L) showed the maximum FRAP and ABTS radical scavenging activity than those prepared using other two enzymes. COS-L had the average molecular weight (MW) of 79 kDa, intrinsic viscosity of 0.41 dL/g and water solubility of 49%. DPPH, ABTS radical scavenging activities, FRAP and ORAC of COS-L were 5.68, 322.68, 5.66 and 42.20 μmol TE/g sample, respectively. Metal chelating activity was 2.58 μmol EE/g sample. For antibacterial activity, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of COS-L against the targeted bacteria were in the range of 0.31–4.91 mg/mL and 0.62–4.91 mg/mL, respectively. Sardine surimi gel added with 1% (w/w) COS-L showed the lower PV, TBARS and microbial growth during 10 days of storage at 4 °C. COS-L from squid pen could inhibit lipid oxidation and extend the shelf-life of refrigerated sardine surimi gel.

Against Aspiration: The Psychogeography of Berlin-Kreuzberg in Stephan Geene’s Umsonst
Authors: Röhrborn Anne 
Published: October 2019

Abstract
Stephan Geene’s film Umsonst premiered in the Forum program at the 2014 Berlinale. A portrait of postmillennial Berlin-Kreuzberg, the film in crucial ways takes its inspiration from the French New Wave and the Situationist International. It focuses on members of a young generation who oppose the economic determinations that frame experience in advanced capitalism. They refuse to fit in and “aspire” and instead become drifters. Employing what the Situationists called a psychogeographic approach, Umsonst probes the prevalent discourses and historical mythologies of Kreuzberg and, in so doing, furthers understanding of how the people who now inhabit it exist and interact.
Searching for a Storyteller, Remediating the Archive: Philip Scheffner’s Halfmoon Files
Authors: Landry Olivia 
Published: October 2019

Abstract
Spurred by the search for the identity of a colonial soldier captured in Germany during World War I, who left his trace in the form of a story in the sound archive in Berlin, Philip Scheffner’s documentary film The Halfmoon Files (2007) is an excavation of an obscured moment in early twentieth-century German history. By way of the figure of the storyteller, read intertextually with Walter Benjamin, this article explores Scheffner’s film as the site of the collision of history and media, where materials of the past come alive in the present through remediation, through which new media revisit the old. The article asserts that the ghost of the storyteller, which haunts this film, returns not in the form of a person but as a hypermedial experience.
Developing pedagogical practices under umbrellas of different colours

Published: October 2019

Artikli eesmärk on tutvustada õpetamise täiustamise võimalusi, milles kombineeritakse tegevõpetajate kutsetööd teadusuuringutega. Ajalooliselt on tegevusuuring, mida hakati rakendama 1940. aastatel, neist uurimisviisidest kõige vanem. Pärast seda on välja pakutud mitmeid raamistikke, mis ühendavad praktilise õpetamistegevuse akadeemiliste püüdlustega, nt arendusuuring, translatiivne uuring, tööviise arendav uuring ja praktikute teadusuuringud ning nende arvukad versioonid ja kombinatsioonid. Selle artikli teine eesmärk on uurida filosoofilisest ja teoreetilisest vaatenurgast uurimistöö teoreetiliste ja praktiliste eesmärkide seost, ühendades Aristotelese klassikalised seisukohad epistemoloogia kohta Jürgen Habermasi teadmiste ja inimlike huvide teooriaga. Metodoloogiana kasutatakse teaduskirjanduse teoreetilist ja filosoofilist analüüsi.

Published: October 2019

The aim of this article is to introduce different ways to conceptualise approaches aimed at improving practices by combining practitioners’ professional work and research. In historical terms, the oldest of these approaches is action research which was introduced in the 1940’s. Thereafter, approaches combining practical work with academic aspirations have been conceptualised in a number of ways, such as design research, translational research, developmental work research (DWR) and practitioner research, and their numerous versions and combinations. Secondly, the purpose of this paper is, from a philosophical and theoretical perspective, to examine the relationship between theoretical and practical aims of research by integrating Aristotle’s classical views on epistemology with the theory of knowledge and human interests of Jürgen Habermas. The methodological approach of this article is a theoretical and philosophical analysis of the literature.

Selle uurimuse tarbeks olen õpetaja ja teadlasena uurinud enda kui õpetaja tööd. Artiklis vastan küsimusele, kuidas kasutada pedagoogilist tegevusuuringut metoodikana, mis võimaldab saada ülevaate sellest, kuidas õpilased tajuvad didaktilisi suhteid. Kirjeldan, kuidas mul õnnestus saavutada õppekavas püstitatud eesmärke ning samal ajal koos õpilastega koguda ja analüüsida uurimisandmeid. Artiklis kasutatud andmed on kogutud narratiivses vormis ja need koosnevad 4. klassi õpilaste loodud 136 pildist ja 25 audiovisuaalsest materjalist (20 pildiraamatut, kolm iMovie videot ja kaks PowerPointi esitlust). Tehtud uuring toetas mitmel tasandil õpilaste kaasatust, mis on pedagoogilise tegevusuuringu põhieesmärk. Õpilastel oli võimalik valida rakendusi ja nii palju pilte, kui nad soovisid. Uuringus kasutatud meetodid pakkusid õpilastele võimalusi avaldada arvamust ainedidaktika ja didaktika põhiküsimuste kohta – mida, kuidas ja miks õppida? – ning võimaldasid mul kujundada oma õpetamistavasid vastavalt õpilaste soovidele. Samas ei suutnud ma selle uuringu raames välja selgitada õpilaste seisukohti nende ja minu vaheliste pedagoogiliste suhete kohta.

A teacher performing action research: capturing pupils’ perspectives of didactic relations
Authors: Niemi Reetta 
Published: October 2019

In this practitioner research, I work as a teacher-researcher and examine my own teaching. In the paper I have answered the question: How can pedagogical action research be used as a methodology in capturing pupils’ perceptions of didactic relations? In this article I describe how I was able to implement the goals set in the curriculum and at the same time collect and analyse data with my pupils. The data for this paper is narrative and it comprises 136 pictures and 25 audio-visual artefacts (20 picture books, three iMovie videos and two PowerPoint presentations) created by 4th grade students. This study supported the pupils’ agency, the core goal of pedagogical action research, on many levels. The pupils were able to choose the number of pictures and the application they wanted to use. The methods used in the study also worked in launching pupils’ perspectives of subject didactics and issues connected to the traditional classification of didactics: what to study, how to study and what purpose to study for and gave me an opportunity to develop my teaching according to the pupils’ wishes. However, in the study I failed to reveal the pupils’ perspectives of the pedagogical relationship between them and myself.

Essee on oma olemuselt terviklik kirjatöö, arvamuse või suhtumise sügavuti väljendus mingil kindlal teemal. Kõrgkoolipedagoogikas on akadeemilist ehk Inglise stiilis esseed kasutatud enamasti individuaalse hindelise kirjutamisülesandena, mis võimaldab subjektiivseid vaatenurki siduda filosoofiliste või teaduslike seisukohtadega. Siinse artikli eesmärk on käsitleda akadeemilise essee kui arutleva tekstitüübi kirjutamisega seotud metodoloogilisi probleeme kirjutamisõpetuse vaatenurgast. Artikkel tugineb tegevusuuringule, mis hõlmab Tartu Ülikooli kultuuriteaduste instituudi eesti kirjanduse eriala bakalaureuseastme kursuse "Proosateksti analüüs" viimase nelja aasta arendustööd. Eri aastakäikude kursustelt kogutud andmete kvalitatiivsest analüüsist selgub, et peamised raskused essee kirjutamisel puudutavad mitmesuguseid tekstiloomeoskusi, nt sobiva analüüsitasandi ja -meetodi valimist, tervikteksti ülesehitust, lõigu struktuuri ja sidusust, argumentide sõnastust. Samas aitasid mitmed ainedidaktilised muudatused – individuaalne konsultatsioon, essee etapiviisiline kirjutamine, nii esma- kui ka lõppvariandi tagasisidestamine – esseede kvaliteeti ja lõpphinnet oluliselt parandada. Artiklis antakse mitmeid didaktilisi soovitusi ja jagatakse veendumust, et essee kirjutamist on võimalik alati tõhusamalt õpetada.

Published: October 2019

Inimesed suhtlevad tekstide vahendusel ja nii on tekstikesksel emakeeleõpetusel oluline roll kirjaoskuse saavutamises. Kirjaoskuse kui üldpädevuse peab aga tagama kool tervikuna. Uurimuse probleemina selgitatakse, kuidas eesti keele ja kirjanduse õpetaja teksti vastuvõttu õpetab ning tekste süsteemse keeleõpetusega seob, et sedamööda leida võimalusi kirjaoskuse koostöiseks õpetamiseks aine- ja keeleõppe lõimingus. Eesmärk on õpetajate kogemuse alusel osutada eesti keele ja kirjanduse didaktika arenguvõimalustele ning kirjeldada eesti keele rolli suhtluspädevuse õpetamisel. Põhistatud uurimusest järeldub, et tekstikeskne keeleõpetus jääb kirjaoskuse arendamisel pigem kõrvale, uut kirjaoskust arendatakse tagasihoidlikult. Samas ilmneb tekstivalikute kaudu emakeeleõpetuse interdistsiplinaarsus. Et arendada kirjaoskuse koostöise õpetamise metoodikat ja tekstikeskset keeleõpetust, pakutakse artiklis ideid nii ülikooli eesti keele ainedidaktika arendamiseks kui ka kirjaoskusõpetuse lõimimiseks õpetajakoolitusse.

Artiklis antakse ülevaade raamatus käsitletavatest teemadest. Täpsemalt analüüsitakse mõningaid intrigeerivaid väiteid, nagu "mõistus ei ole loodud õppimiseks", "head teadmised takistavad õpetamist", "õpetaja peaks olema muutuste põhjustaja", mis suunavad lugejat mõtlema. Raamatu tugev külg on ka tekstikastid ja küsimused järelemõtlemiseks. Tegu on vajaliku raamatuga, kuid selleks, et saada põhjalik ülevaade õppimisest ja õpetamisest, on sellele lisaks vaja lugeda teisi raamatuid.

Published: October 2019

Introduction Colonic stent insertion has been shown to be an effective treatment for patients with acute large bowel obstruction, either as a bridge to surgery or as definitive treatment. However, little is known of the role of secondary stent insertion following primary stent failure in patients considered inappropriate or high risk for emergency surgery. Methods Fourteen patients presenting with acute large bowel obstruction who had previously been treated with colonic stent insertion were studied. All underwent attempted placement of a secondary stent. Results Technical deployment of the stent was accomplished in 12 patients (86%) but only 9 (64%) achieved clinical decompression. Successful deployment and clinical decompression of a secondary stent was associated with older age (p=0.038). Sex, pathology, site of obstruction, duration of efficacy of initial stent and cause of primary failure were unrelated to outcome. No procedure related morbidity or mortality was noted following repeated intervention. Conclusions Secondary colonic stent insertion appears an effective, safe treatment in the majority of patients presenting with acute large bowel obstruction following failure of a primary stent.

Iron toxicity is a factor causing low rice yield on tidal swamp land (TSL).Soil quality improvement by using water management, organic matter and introducing adaptable varietywere some options to increaseits productivity in the soils. Field experiment was conducted to evaluate effects of applying water management, organic matter and adaptable variety to increase its productivity on a TSL of KP Belandean, Barito Kuala District of South Kalimantan, during dry season of 2010. The research was arranged in a split-split-plot design with three replicates. The main plots were two water management, i.e: P0 = without water management (control) and P1= intermittent water management, while sub plots were three organic matter application, i.e: B0 = without organic matter application (control), B1 = straw compost 3 t/ha, B2 = manure 2 t/ha, and sub sub plots were five rice varieties, i.e. V1 = Mekongga, V2 = Inpari 1, V3 = Ciherang, V4 = Silugonggo and V5 = Margasari. The result showed that there was interaction between water management and variety tested on rice yield in TSL. The highest yield was reached by Inpari 1 variety which treatment intermitten water management, with yield i.e. 5.390 t/ ha.Silugonggo and Ciherang was not suitable to cultivate on TSL. The implication of this research was variety recomendation on a tidal swamp land, i.e. Inpari 1 variety and intermitten water management.

Published: October 2019

Pitcher plants (Nepenthes spp.) that known as “Carnivorous plants”, has a role in CO2 absorption. However, how much contribution to the CO2 absorption has not been studied. This study was aimed to provide information on CO2 absorption of some Nepenthes species particularly lowland species. This study was conducted at Research Center for Biology-Indonesian Institute of Sciences, Cibinong Science Center, Cibinong-West Java in June 2014 . A portable LCi ADC Bioscientific Ltd. Photosynthesis System was used to measure the absorption of CO2 directly. Measurement was conducted on 45 individuals of 15 species of Nepenthes with three replications for each species. The results showed that there was a variation of CO2 absorption rate on the lowland Nepenthes species, which was between 3.74 to 12.15 µmol m-2 s-1. The highest CO2 absorption was N. mirabilis (12.15 µmol m-2 s-1), followed by N. gracilis (9.71 µmol m-2s-1) and N. reinwardtiana (9.30 µmol m-2 s-1). While the lowest CO2 absorption occured in N. ampullaria (3.74 µmol m-2 s-1), N. hispida (3.75 µmol m -2 s-1) and N. bicalcarata (4.53 µmol m-2 s-1). Mature leaves of each species were recorded to have a highest CO2 absorption, transpiration and chlorophyll content than those of the young leaves.

Various studies indicated that endophytic microbes lived in the plant tissues and produced antimicrobial compounds. Sugar-apple plant (Annona squamosa L) contained alkaloids, cyanogenic glycosides, and flavonoids. The purpose of this reasearch were (1) to determine the endophytic microbes isolated from sugar-apple plant (2) to study inhibiting capabillity of endophytic isolate against Staphylococcus aureus and Candida albicans, (3) to analyze antimicrobial compounds produced by the potential endophytic isolate. Diffusion agar plate methode was used to assessed antimicrobial activity. Antimicrobial compounds were analyzed by Thin Layer Chormatography (TLC) and High Performance Liquid Chormatography (HPLC), compared with erythromycin, metronidazole and tetracycline. Twelve bacterial isolates and 24 fungus were isolated. Selected bacteria, BMC 1.1, showed the biggest clear zone on C. albicans culture on agar medium, meanwhile selected fungi, BTCK 1.1T, formed the biggest colony on S. aureus culture on agar medium. TLC and HPLC analysis showed that the Rf value of BMC 1.1 and BTCK 1.1T chloroform phase fractions was similiar to metronidazole. Metronidazole concentration in C1, C2, Ck1 and Ck2 fraction were 170.98 ppm, 18.27 ppm, 1.51 ppm and 4.14 ppm respectively.

Aquilaria malaccensis Lam. is a plant species producing fragrant woody material that contains some resin. The compounds can be used as medicine and perfume. Sesquiterpenoid, one group of compounds has been found being synthesized and subsequently extracted from callus and cell suspension culture of Aquilaria species. The aim of this research was to find a method of producing friable calli and cell suspension cultures from leaves or internodes of A. malaccensis in vitro by using suitable plant growth regulators; cell suspension that will suitably serve as material to produce sesquiterpenoid afterwards. Calli were established in almost all treatments of auxin-cytokinin on both leaves and internod explants. The treatment of 10 mg/L IBA induced the highest percentage of callus coverage from leaves with a rather compact structure. The combined treatment of 1–2 mg/L 2.4-D and 0.2–0.3 mg/L BA induced friable callus formation in more than 80% of cultures with 27–32% callus coverage percentage. The use of 2,4-D induced a better formation of cell suspension than Picloram, with maximum volume up to 7 mL. Cell suspension culture with fine and homogenous aggregate could be established in the medium supplemented with 0.5 –1 mg/L 2,4-D.
