Oralidad: fundamento de la didáctica y la evaluación del lenguaje
Authors: Uribe-Hincapié Richard Alonso , Montoya-Marín Juan Eliseo , García-Castro Juan Fernando
Published: April 2020

La oralidad es la primera forma simbólica de relación con el mundo. Esto es así no solo por la disposición antropológica de las relaciones humanas (interhumanas y humanas con otras formas de vida), sino porque constituye, tal vez, la única prótesis establecida como dispositivo racional y razonable que provee al mismo tiempo una estructura múltiple, tanto para la hominización como para la humanización. Esta condición particular del lenguaje humano articulado, del cual puede decirse que está cercano a la perfección, dados los minúsculos cambios a los que se ha visto sometido desde su aparición hasta hoy, actúa, entonces, como culmen y medida de lo que puede considerarse cultural, simbólico, representativo, identificatorio y, por supuesto, humano. Paradójicamente, en el escenario escolar, la oralidad se comprende como una manifestación de lo humano que carece de representatividad, potencia académica y carácter identificador social y cultural, lo que la confina a una condición secundaria y dependiente de la escritura, y a una abolición educativa y pedagógica que le impide ser objeto de estudio e investigación de maestros y estudiantes. En el marco de esta problemática se propone la oralidad como fundamento para pensar la didáctica y la evaluación del lenguaje y como cimiento para la formación y la transformación de los sujetos y la sociedad.
Satisfação profissional de enfermeiros que atuam no bloco cirúrgico de um hospital de excelência
Authors: Gouveia Lúcia Helena De Almeida , Ribeiro Vivian Finotti , Carvalho Rachel De
Published: April 2020

Objetivos: Analisar e comparar o índice de satisfação profissional (ISP) de enfermeiros do bloco cirúrgico (BC). Método: Estudo de campo, comparativo e quantitativo que utilizou o ISP na avaliação da autonomia, interação, remuneração, normas organizacionais, status profissional e requisitos do trabalho de enfermeiros atuantes do BC de um hospital privado de São Paulo. Resultados: Dos 49 enfermeiros da amostra, 39 atuavam em centro cirúrgico (CC) e sala de recuperação pós-anestésica (SRPA) e 10 no centro de material e esterilização (CME). A interação foi o componente de maior importância, e o status profissional, o de menor, no entanto status profissional obteve o maior nível de satisfação, e requisitos do trabalho, o menor. O ISP foi 11,04 (baixo nível), considerando possível variação entre 0,9 e 37,1. Houve diferença significante para interação, com maior satisfação dos enfermeiros do CC/SRPA em comparação com os do CME. Conclusão: A satisfação profissional de enfermeiros do BC avaliada pelo ISP foi baixa. Conhecer os fatores que influenciam nesse índice é importante, pois a satisfação interfere diretamente na qualidade da assistência, previne doenças ocupacionais, além de ser indicador de resultados no processo de trabalho.

Problem Animals
Authors: Peterson Anna ,   Center for Environmental Philosophy, The University of North Texas
Published: April 2020

Nonhuman animals play various roles in environmental ethics, often as charismatic symbols of wilderness or active participants in the natural dramas we seek to preserve. Sometimes, however, nonhuman animals do not fit into—and may even threaten—the “nature” that we value. There are two especially problematic animals: white-tailed deer and feral cats. Together, these creatures shine light on a number of important issues in environmental ethics, including the tensions between animal welfare and environmentalism, the ways human interests and categories pervade even ecocentric perspectives, and the complex place of science in environmental ethics and advocacy. Thinking through the issues raised by debates about deer and cats can contribute to a more adequate treatment of nonhuman animals in environmental thought and advocacy.
Existence Value, Preference Satisfaction, and the Ethics of Species Extinction
Authors: Stabell Espen Dyrnes ,   Center for Environmental Philosophy, The University of North Texas
Published: April 2020

Existence value refers to the value humans ascribe to the existence of something, regard­less of whether it is or will be of any particular use to them. This existence value based on preference satisfaction should be taken into account in evaluating activities that come with a risk of species extinction. There are two main objections. The first is that on the preference satisfaction interpretation, the concept lacks moral importance because satisfying people’s preferences may involve no good or well-being for them. However, existence value can be based on a restricted version of the preference satisfaction theory, which is not vulnerable to the skeptical arguments about the link between preference satisfaction and well-being. The second objection is that even if preference satisfaction can be linked to well-being, understanding existence value in terms of individual preference satisfaction is incoherent, because existence value reflects disinterested preferences that involve no benefits to the individual. However, the fact that existence value may involve disinterested preferences does not threaten the coherence of the concept, but suggests that it does not fit smoothly into the “utilitarian” or “welfarist” framework it is commonly considered within. A pluralistic normative approach based on prima facie duties can be an alternative to standard utilitarian-style approaches for considering existence value in concrete cases involving a risk of species extinction, such as through deep sea mining.
“The Great Burden” of Religion
Authors: Bancalari Stefano ,   DePaul University
Published: April 2020

This article aims to reread Jonas’s famous lecture on “Heidegger and Theology” linking it with a still unpublished lecture course on Being and Time Jonas held in 1967 at the New School for Social Research. From the reading of Heidegger’s masterwork, Jonas takes the idea of the “burdensome” character of the existence, which he interprets in terms of a “polarity” between man and his “other” (other men, God, world). Such a polarity is for Jonas the very essence of “religion” (as religamen) and of responsibility. From this vantage point, “Heidegger and Theology,” with its sharp criticism of the theological appropriation of Heidegger’s post-turn philosophy, appears to be a strong defense of the burden of “polarity,” as developed in Being and Time, against its removal by the thought of Being: a Being which is nothing but a mirror image of Dasein. Partially reconsidering his views on Heidegger’s Gnosticism, Jonas turns (the earlier) Heidegger against (the later) Heidegger himself.

LA POESÍA DE JUAN MALPARTIDA COMO CONSTRUCCIÓN DE SENTIDO
Authors: ABRIL PALACIOS Juan Carlos
Published: April 2020

Resumen: La obra poética de Juan Malpartida no se ajusta al canon español de las últimas décadas. La perspectiva que otorga su obra poética reunida se vincula a la modernidad de la que habla Octavio Paz, las corrientes europeas de vanguardia, y no al realismo, tan característico de España. Su poesía busca la construcción del sentido a través de una semiosfera —en términos lotmanianos— que indaga en la arqueología del sable, tal y como quería Foucault. Se ponen en otra dirección semántica los símbolos, en su mayoría bisémicos, y las palabras, motivadas por la influencia de otras tradiciones. De este modo se articula la interdisciplinariedad de otras artes,su transversalidad, la lectura mitocrítica de la cotidianidad, la relación gestáltica entre teoría y práctica, la función cognitiva de la escritura, o la reflexión metapoética. Resumen: La perspectiva de la obra poética de un autor como Juan Malpartida no se ajusta al canon español de las últimas décadas.

Mentoria formal como estratégia de ação para a formação de competências criativas
Authors: Pereira Marcela Rebecca , Mendonça José Ricardo Costa de , Santos Júnior Luiz Sebastião dos
Published: April 2020

Este ensaio teórico tem o objetivo de apresentar o processo de mentoria formal, dentro da lógica das funções de mentoria, como uma alternativa estratégica interessante para a formação de classes criativas em oposição à visão tradicional de captação de recursos humanos criativos. O que se percebe é que parte dos estudiosos tem se concentrado na atração de pessoas criativas e num certo determinismo histórico-geográfico que imana valores culturais os quais por sua vez geram, respectivamente, pessoas criativas, classes criativas e, consequentemente, contextos criativos que, a partir daí, se retroalimentariam. Essa lógica é claramente suportada pela abordagem estratégica baseada em recursos, dentro de uma perspectiva cultural, onde pessoas, sua cultura e sua criatividade são elementos valiosos, raros e de difícil imitação. Resultados de pesquisas têm comprovado a validade da mentoria como um mecanismo crítico para o desenvolvimento de talentos em grandes empresas, especialmente no setor público. Como nem sempre é possível, pelo menos em um instante inicial, atrair recursos valiosos em quantidade significante, verifica-se que a formação de tais recursos humanos possa significar uma vantagem competitiva interessante às cidades que têm a pretensão de se destacar competitivamente por tal capacidade de inovação, criatividade e geração de novas perspectivas econômicas, sociais, políticas e, sobretudo, culturais.

Authors: Riaz Talha , Tande Aaron J. , Steed Lisa L. , Demos Harry A. , Salgado Cassandra D. , Osmon Douglas R. , Marculescu Camelia E.
Published: April 2020

Abstract. Background: Fungal prosthetic joint infections (PJIs) are rare and often associated with poor outcome; however, risk factors are not well described.Methods: This was a retrospective case control study among all patients with PJIs from 2006-2016 at two major academic centers. Each fungal PJI case was matched 1:1 with a bacterial PJI control by joint (hip, knee, shoulder) and year of diagnosis. We compared demographics, comorbidities, and clinical characteristics between cases and controls using chi square/Fisher's exact or Wilcoxon rank sum test. Independent risk factors were identified with multivariable logistic regression.Results: Forty-one fungal PJIs occurred over the study and 61% were due to Candida albicans. The hip was involved in 51.2% of cases, followed by the knee (46.3%). Compared to bacterial PJI, fungal PJI cases were more likely to have received antibiotics within the previous 3 months (70.7% vs 34%, P=.001), wound drainage lasting >5 days (48% vs 9%, P=.0002), had a lower median CRP (2.95 mg/dl vs 5.99, P=.013) and synovial fluid white blood cell count (13,953 cells/mm3 vs 33,198, P=.007), and a higher proportion of prior two-stage exchanges (82.9% vs 53.6%, P=.008). After controlling for center, prolonged wound drainage (OR, 7.3; 95% CI, 2.02-26.95) and recent antibiotics (OR, 3.4; 95% CI, 1.2-9.3) were significantly associated with fungal PJI.Conclusion: In our study, Candida albicans was the most common species in fungal PJIs and prolonged wound drainage and recent antibiotics were independent risk factors. These clinical characteristics may help providers anticipate fungal PJI and adjust management strategies.
System for assessment of personal and professional suitability of IT staff in government organizations
Authors: Noss Igor' Nikolaevich , Kovaleva Mariya Evgen'evna
Published: April 2020

The subject of this article is the development of psychological model for assessing personal and professional suitability of IT staff in government organizations applicable in human resource management. Firstly, the author highlights personality and professional traits, builds a mathematical model that allows correlating the manifestation of these traits (grouped into modules-predicators) with professional aptitude of IT personnel. Secondly, the author builds a formal-mathematical model on the bases of multiple linear regression equation for assessing the manifestation of personality and professional qualities using the psychodiagnostic methods at the stage of job placement of IT professionals. The scientific novelty consists in the analysis of literature that demonstrated insufficient research dedicated to professionally important qualities of IT personnel, as well as rare application of psychological modeling as the means for job placement and assessment of employees in all spheres. The main conclusion lies in determination of veracity of psychodiagnostic means for assessment of personal and professional suitability of IT personnel. The acquired model can be valuable in future research of professional aptitude, as well as implemented in human resource management.
Play-based test for assessing the level of social intelligence among preschoolers and elementary schoolers
Authors: Chesnokova Olga Borisovna , Subbotsky Eugene , Martirosova Yuliya Viktorovna
Published: April 2020

  The need in social intelligence emerges when there is clash of interests and a work-around solution is required for successful interaction. Obstacles towards achieving the goal motivates a person to look for unconventional solutions to a communication problem. Matrix of a new social intelligence test among preschoolers and elementary schoolers is proposed. The advantage of this test over the traditionally used picture-based surveys is that it does not require a developed symbolic function. As a prototype of the simulated communication situation, the author used a situation of uncertainty in achieving the goal, clash of interests of the characters, and more than one scenario of finding a work-around solution for reaching a desirable result. These requirements were met by the attempt to rob the armored truck by a criminal who was able to eavesdrop on the conversation between the driver and the dispatcher to determine which of the simultaneously traveling trucks carried the money. The driver had to report to the dispatcher in a way that would be understood by the dispatcher, but not the criminal. Unlike the earlier methods of assessment of social intelligence, the proposed play-based is built upon realistic simulation that can be understood by children aged 6-12. This simulation allows for careful assessment of social intelligence of children involved into a captivating game of finding optimal behavioral strategy in a situation where they have to communication with a partner, while encrypting the information for other people, but without outright lying.  
Spirituality in modern education: necessity or excess?
Authors: Gryaznova Elena Vladimirovna , Goncharuk Aleksey , Fedorenko Irina Evgen'evna , Treushnikov Aleksei Il'ich
Published: April 2020

This article examines the points of view of modern scholars, pedagogues and theologians upon the problem of the loss of spirituality in the current system of education in Russia. The authors analyze the two extreme opinions. The first one consists in the need for reviving the spiritual component in education. The loss of spirituality in this sphere led to dropping of value orientations, national unity and cultural identity of the modern generation of Russians. The second opinion reflects the views of scholars that in the information society an individual can combine the qualities of intellectual ruler of life and spirituality. In this case, the loss of spirituality is considered a natural human improvement process. As a result of the analysis of both points of view on the role of spirituality within the modern education system, the authors believe that the solution should be found in harmonization of secular and religious education in the conditions of development of information society. This problem could be solved with introduction of theology as a scientific specialty, which would allow preparing theologians of new generation. The next stage in studying this problematic would consist in the examination of experience of implementation of theological education in different Russian universities, namely Kozma Minin Nizhny Novgorod State Pedagogical University, since it features Bachelor’s and Master’s programs of Orthodox theology.
On some aspects of practical work with night dreaming
Authors: Bogachev Aleksei Mikhailovich
Published: April 2020

In modern practical psychology, the work with imagination as a whole, and night dreaming in particular, is of considerable importance. Various approaches offer different interpretation of the essence of night dreaming state, and thus, diverse techniques of working with a client. However, the demand for the universal synthetic approach within the framework of psychological aid (consulting psychology, correctional psychology, and (or) nonmedical psychotherapy) is highly relevant in both, theoretical and applied aspect. The author attempt to answer such request based on the experience acquired in the process of rendering practical psychological aid. The object of this study is psychical reality of the recipients of psychological services. The subject is the state of consciousness during sleep of the recipients of psychological services. The main conclusion consists in proving the efficiency of the synthetic approach towards work with night dreaming developed and tested by the author of the article. The scientific and applied novelty of this approach lies in the ability to overcome a range of difficulties faced by the practitioners in the area of depth psychology.

Authors: Jafarin Sara , Mohammadnejad Pooya
Published: April 2020

The use of edible coatings is a suitable method to reduce oil uptake in fried foods. In this research, the effects of propolis gum on the physicochemical properties of fried potato strip were evaluated.

The propolis coating was performed at three concentrations 1%, 1.5%, 2% w/v. Potato strips were dipped in the coating solutions followed by air drying. Viscosity of coating was measured in two shear rate 0.048 and 62.11 1/s. The treatments were fried in canola oil and analyzed for fat uptake and moisture retention.

One-way analysis of variance (ANOVA) was used and mean comparison was performed by Duncan’s new multiple range test.

The results showed that by increasing in shear rate, viscosity of coating was decreased. By increasing in propolis concentration, the coating pick up, moisture content, frying yield, were increased while oil uptake were decreased.

According to the results, 2% concentration propolis gum reduced oil absorption in fried potato strips. Due to their facility to use, propolis gum suggested for coating and usage in industrial potato fries production.

Authors: Ofori E. O. , Alhassan B. A. Bin , Akakpo K. , Imbeah E. G. , Asante-Asamani A. , Maison P. , Rahman G. A.
Published: April 2020

Introduction: Renal oncocytomas are benign tumours arising from the intercalated cells of the collecting ducts and account for 3% to 7% of primary renal tumours. It was first described by Zippel in 1942. Oncocytomas are mostly asymptomatic and often discovered incidentally. They are often diagnosed postoperatively due to clinical and radiographic challenges in differentiating them from renal cell carcinoma.

Presentation of Case: The present study reports two cases of renal oncocytoma in a 61‑year‑old man who was asymptomatic and a 73‑year‑old woman who was symptomatic. Relevant clinical and imaging data on the two patients were reviewed. Both patients underwent nephrectomy via flank incisions.

Discussion: The typical morphologic features of oncocytoma were observed on histological examination of the excised kidney speci­mens. The postoperative course of each patient was uneventful and they were discharged 14 and 6-days post‑surgery, respec­tively. In addition, the present study reviews the literature regarding the clinical, radiological and pathological characteristics of renal oncocytoma.

Conclusion: Renal oncocytoma though is benign and has an excellent prognosis, the preoperative diagnostic challenges invariable warranted radical nephrectomy.
Optimization of Some Nutritional Conditions and α- Ketoglutaric Acid Concentration as PGA Precursor for Maximizing PGA Production from Bacillus sp. 42 and Bacillus sonorensis 44
Authors: Ahmed Rania F.
Published: April 2020

Poly gamma glutamic acid is a biodegradable, water soluble and non-toxic edible biopolymer, PGA has nylon back bone similar structure and expressed as bio-nylon. Various bacterial strains produced PGA on of them Bacillus sp. such as B. subtilis, B. lichanformans and B. sonorensis. Polymer yield was affected with medium composition as nitrogen and carbon sources. The current experimental was carried out using shake flask technique for PGA production during 72 of fermentation. The highest biomass was achieved at glycerol media and glucose media for PGA yield and productivity being 2.31, 9.65 gl-1 and 0.134 gl-1h-1, respectively of B. sonorensis 44. Of nitrogen source, organic source (yeast extract) was higher PGA yield  and productivity than inorganic sources (NH4NO3) which reduced PGA yield about 28.7 and 36.02% of Bacillus sp. 42 and B. sonorensis 44, respectively. Production media supple-  mented with 0.5 and 0.75 gl-1 α-keto-glutaric acid increased PGA yield about 1.24fold for both Bacillus strains. Osmotic pressure of 2.55 MPa (3% NaCl) enhanced PGA yield about  1.18 and 1.24fold of Bacillus sp. 42 and B. sonorensis 44, respectively. Furthermore, the highest PGA was received using medium containing glucose and yeast extract (as C and N2 sources). α-keto-glutaric acid and osmotic potential has an induction effect for polymer accumulation.
Estimation of Fuel Burnup Rate for Core Conversion for the Nigeria Research Reactor-1 (NIRR-1) Fueled With 19.75% Enriched UO2 USING VENTURE PC Code
Authors: Rabba J. A. , Onimisi M. Y. , Samson D. O.
Published: April 2020

A standardized burnup analysis using VENTURE-PC computer codes system has been performed for the core conversion study of Nigeria Research Reactor-1. The result obtained from this analysis showed that the mass of Uranium decreases with increase in the number of days of reactor operation while the quantity of Plutonium continues to build up linearly. The buildup of the fissile isotope in the Low Enriched Uranium (LEU) core is very much greater than in the Highly Enriched Uranium (HEU) core. The quantity of Uranium-235 consumed and the amount of Plutonium-239 produce in the core of the reactor were 13.95 g and 0.766745 g respectively for the period of 11 years of reactor operation which is in good agreement with other literatures. This results obtained showed that uranium dioxide (UO2) fuel is a potential material for future Low Enriched Uranium (LEU) core conversion of Nigeria Research Reactor.
Quality assurance of VMAT on flattened and flattening filter‐free accelerators using a high spatial resolution detector
Authors: Matar F. S. , Wilkinson D. , Davis J. , Biasi G. , Causer T. , Fuduli I. , Brace O. , Stansook N. , Carolan M. , Rosenfeld A. B. , Petasecca Marco
Published: April 2020

Purpose

This study investigated the use of high spatial resolution solid‐state detectors (DUO and Octa) combined with an inclinometer for machine‐based quality assurance (QA) of Volumetric Modulated Arc Therapy (VMAT) with flattened and flattening filter‐free beams.

Method

The proposed system was inserted in the accessory tray of the gantry head of a Varian 21iX Clinac and a Truebeam linear accelerator. Mutual dependence of the dose rate (DR) and gantry speed (GS) was assessed using the standard Varian customer acceptance plan (CAP). The multi‐leaf collimator (MLC) leaf speed was evaluated under static gantry conditions in directions parallel and orthogonal to gravity as well as under dynamic gantry conditions. Measurements were compared to machine log files.

Results

DR and GS as a function of gantry angle were reconstructed using the DUO/inclinometer and in agreement to within 1% with the machine log files in the sectors of constant DR and GS. The MLC leaf speeds agreed with the nominal speeds and those extracted from the machine log files to within 0.03 cm s−1. The effect of gravity on the leaf motion was only observed when the leaves traveled faster than the nominal maximum velocity stated by the vendor. Under dynamic gantry conditions, MLC leaf speeds ranging between 0.33 and 1.42 cm s−1 were evaluated. Comparing the average MLC leaf speeds with the machine log files found differences between 0.9% and 5.7%, with the largest discrepancy occurring under conditions of fastest leaf velocity, lowest DR and lowest detector signal.

Conclusions

The investigation on the use of solid‐state detectors in combination with an inclinometer has demonstrated the capability to provide efficient and independent verification of DR, GS, and MLC leaf speed during dynamic VMAT delivery. Good agreement with machine log files suggests the detector/inclinometer system is a useful tool for machine‐specific VMAT QA.
Does potentially mineralizable nitrogen predict maize yield in newly cropped soil?
Authors: Gebremedhin Maheteme , Sarr Sait , Coyne Mark , Freytag Ann , Sistani Karamat R.
Published: April 2020

Fallow soils converted to crop use have unpredictable soil organic nitrogen (SON) availability during the growing season, which incentivizes over‐applying fertilizer N by way of compensation. Potentially mineralizable nitrogen (PMN) is a soil health indicator, and its increase is a management strategy to meet crop N demands. How well does PMN predict yield in transition, periods from fallow to crop, especially when conservation practices are imposed simultaneously? In a short‐term study, conducted in Madison County, Kentucky (37.85 N, 84.29 W) from 2015 to 2017, we tested the hypothesis that implementing conservation practices (use of cover crops and manure) during the transition period would mitigate adverse effects on N availability by increasing PMN and significantly benefit maize (Zea mays L.) grain yield. Six treatments were used: (a) an unamended control; (b) cover crops; (c) horse manure; (d) cover crops and horse manure; (e) chemical fertilizer; and (f) cover crops and chemical fertilizer. Soils were sampled after cover crop termination, before manure or fertilizer application in spring, and at fall harvest each year and analyzed for PMN. The seasonal PMN and maize grain yield were influenced by cover crops and manure (p < .05). Maize grain yield had a positive response to cover crops but not manure. The correlation between PMN and grain yield, though positive, was very weak (R2 = .03). We conclude that conservation practices, particularly cover crops, in the transition period can benefit PMN and crop yield, but PMN is not a good predictor of yield during transition stages.

The Soil Management Assessment Framework (SMAF) may provide insight into how conservation practices affect soil quality (SQ) regionally. Therefore, we aimed to quantify SQ in a long‐term (15‐yr) crop rotation and bio‐covers experiment under no‐tillage using SMAF. Main effects were cropping rotations of soybean [Glycine max (L.) Merr.], corn (Zea mays L.), and cotton (Gossypium hirsutum L.). Split‐block bio‐cover treatments consisted of winter wheat (Triticum aestivum L.), Austrian winter pea (Pisum sativum L. sativum var. arvense), hairy vetch (Vicia villosa Roth), poultry litter, and fallow (control). Seven SQ indicators—soil pH, total organic carbon (TOC), bulk density (BD), soil extractable P and K, electrical conductivity (EC), and sodium adsorption ration (SAR)—were scored using SMAF algorithms, and investigated individually and as an overall soil quality index (SQI). Simple linear regressions were performed between SQI and crop yields. Differences (p < .05) in SQI within rotations varied when analyzed across and by depth. Overall, cotton–corn and/or continuous corn had greater SQI than soybean‐based rotations. Poultry litter had the greatest TOC, pH, K, and BD scores at the 0‐ to 15‐cm soil depth, and the lowest SQI. Reductions in SQI within bio‐covers were linked to P scores. A positive relationship was found between SQI and cotton yield at the 15‐ to 30‐cm soil depth (R2 = .48; p < .05). Investigating SMAF scores individually and separately per depth addresses the effects of long‐term conservation practices on SQ. Overall, SMAF can be used to develop best management practices and nutrient management strategies.

Separation of linear and branched isomers is of great commercial significance but still one of the energy‐intensive and challenging processes in petrochemical industry. Here, we for the first time report a tailor‐made metal–organic framework, ZU‐36‐Co (also termed GeFSIX‐3‐Co, GeFSIX = GeF62−, 3 = pyrazine), for the separation of both C4 linear/branched olefins (n−/iso‐C4H8) and paraffin isomers (n−/iso‐C4H10). With the pore size ranged between 3.82–5.25 Å, ZU‐36‐Co traps a large amount of n‐C4H8 (2.35 mmol/g) and n‐C4H10 (2.20 mmol/g) with iso‐C4H8 and iso‐C4H10 excluded. The molecular exclusion effect illustrates the significance of tailor‐made pore window size for gas separation. To our knowledge, ZU‐36‐Co exhibits the highest n−/iso‐C4H8 uptake ratio (13.8) and superior n−/iso‐C4H10 separation performance compared with the state‐of‐the‐art materials and sets a benchmark for the separation of linear and branched C4 isomers. This excellent molecular exclusion effect of ZU‐36‐Co was further confirmed by mixed gas breakthrough tests.

Outcome of Helicobacter pylori (H. pylori) infection in a specific individual is unpredictable and results from interaction of multiple variables, including host genetic factors. This study aimed to investigate if NOD2 mutations increased the risk of H. pylori infection and if it has any relationship with bacterial genotype or gastric histopathological modifications. This prospective study involved 86 patients (54 females; mean age, 48.7 ± 13.6 years) with positive 13C‐urea breath test (UBT) and a sex and age‐matched control group of 266 individuals, 64 of them with negative UBT. The three main NOD2 mutations (L1007fsinsC, R702W, and G908R) were obtained for all patients and controls. Fifty‐one infected patients were submitted to endoscopy with gastric biopsies. H. pylori was isolated, and genotypes were determined by PCR. Histopathological features were graded according to the updated Sydney system. Overall, NOD2 mutations were found in 14 patients (16.3%) and in 31 controls (11.7%) (OR = 1.40, 95% CI = 0.78‐2.50; P = .264). Genotype frequencies for L1007fsinsC (1.2% vs 0.8%), R702W (11.6% vs 7.6%) and G908R (5.8% vs 3.4%) were not statistically different between the two groups. A significant positive association was observed between NOD2 polymorphisms and peptic ulcer but only in univariate analysis. There were no other correlations with clinical variables, gastric histological patterns and H. pylori genotypes. NOD2 mutations are not associated with increased prevalence of H. pylori infection or more severe gastric histopathological modifications induced by this bacterium. However, such host polymorphisms could influence clinical manifestations.

Objective

Observational studies point to an inverse correlation between low‐density lipoprotein (LDL) cholesterol levels and risk of intracerebral hemorrhage (ICH), but it remains unclear whether this association is causal. We tested the hypothesis that genetically elevated LDL is associated with reduced risk of ICH.

Methods

We constructed one polygenic risk score (PRS) per lipid trait (total cholesterol, LDL, high‐density lipoprotein [HDL], and triglycerides) using independent genomewide significant single nucleotide polymorphisms (SNPs) for each trait. We used data from 316,428 individuals enrolled in the UK Biobank to estimate the effect of each PRS on its corresponding trait, and data from 1,286 ICH cases and 1,261 matched controls to estimate the effect of each PRS on ICH risk. We used these estimates to conduct Mendelian Randomization (MR) analyses.

Results

We identified 410, 339, 393, and 317 lipid‐related SNPs for total cholesterol, LDL, HDL, and triglycerides, respectively. All four PRSs were strongly associated with their corresponding trait (all p < 1.00 × 10‐100). While one SD increase in the PRSs for total cholesterol (odds ratio [OR] = 0.92; 95% confidence interval [CI] = 0.85–0.99; p = 0.03) and LDL cholesterol (OR = 0.88; 95% CI = 0.81–0.95; p = 0.002) were inversely associated with ICH risk, no significant associations were found for HDL and triglycerides (both p > 0.05). MR analyses indicated that 1mmol/L (38.67mg/dL) increase of genetically instrumented total and LDL cholesterol were associated with 23% (OR = 0.77; 95% CI = 0.65–0.98; p = 0.03) and 41% lower risks of ICH (OR = 0.59; 95% CI = 0.42–0.82; p = 0.002), respectively.

Interpretation

Genetically elevated LDL levels were associated with lower risk of ICH, providing support for a potential causal role of LDL cholesterol in ICH. ANN NEUROL 2020 ANN NEUROL 2020;88:56–66
Chemoselective N−H insertion catalyzed by a de novo carbene transferase
Authors: Stenner Richard , Anderson John Leslie Ross
Published: April 2020

The ability to perform organic reactions with chemoselectivity is of critical importance in synthesis. Recently, we reported that a de novo carbene transferase, a tetra‐α‐helical c‐type heme‐containing protein, C45, is proficient at N−H insertion reactions, proceeding via the intermolecular transfer of a metallocarbenoid intermediate into the N−H σ‐bond to form a new N−C σ‐bond. Here we demonstrate that C45 can also catalyse N−H insertion reactions chemoselectively, even when the substrate contains an unprotected hydroxyl group.

Published: April 2020

The development of digital pathology and progression of state‐of‐the‐art algorithms for computer vision have led to increasing interest in the use of artificial intelligence (AI), especially deep learning (DL)‐based AI, in tumor pathology. The DL‐based algorithms have been developed to conduct all kinds of work involved in tumor pathology, including tumor diagnosis, subtyping, grading, staging, and prognostic prediction, as well as the identification of pathological features, biomarkers and genetic changes. The applications of AI in pathology not only contribute to improve diagnostic accuracy and objectivity but also reduce the workload of pathologists and subsequently enable them to spend additional time on high‐level decision‐making tasks. In addition, AI is useful for pathologists to meet the requirements of precision oncology. However, there are still some challenges relating to the implementation of AI, including the issues of algorithm validation and interpretability, computing systems, the unbelieving attitude of pathologists, clinicians and patients, as well as regulators and reimbursements. Herein, we present an overview on how AI‐based approaches could be integrated into the workflow of pathologists and discuss the challenges and perspectives of the implementation of AI in tumor pathology.

Introduction

Necrotizing periodontitis (NP) is an atypical and painful form of periodontal disease, it is described by a promptly progress of ulceration and destruction of periodontal tissues; the NP is commonly linked to HIV‐positive patients. The aim of this report is to present a rare case of severe necrotizing ulcerative periodontitis treated non‐surgically.

Case Presentation

A 28‐year‐old dark skin female patient was referred to a dentistry college with the main complaint of spontaneous gingival bleeding and enlargement, oral pain during deglutition and dental hypersensitivity. Clinical and radiographic examination revealed generalized severe periodontal destruction, extensive bleeding, increased biofilm presence and spontaneous suppuration. Medical exams were requested, red and white blood cells were evaluated and among those exams an enzyme‐linked immunosorbent assay for HIV‐1 antibodies, the result reveled reagent to HIV‐1. The diagnosis of NP was assigned based on periodontal parameters such as necrosis and ulceration of the coronal portion of interdental papillae and gingival margin. Treatment established was scaling and root planning plus antibiotics. At 3 months of treatment the clinical and periodontal condition were stable.

Conclusion

This case report highlights a severe and generalized form of NP, where periodontal non‐surgical associated with antimicrobials resulted in elimination of the gingival enlargement, necrosis and ulceration of the coronal portion of interdental papillae and significant improvement of periodontal parameters.
The Merit to Phenotypic Modification Treatment for Dental Implants: Two Case Reports
Authors: Rosen Paul S.
Published: April 2020

Introduction

The American Academy of Periodontology convened a Best Evidence Consensus workgroup in August 2019 in Chicago, IL to address whether the conversion of a thin to a thick tissue phenotype through various phenotype modification therapy (PhMT) can positively influence peri‐implant health.

Case Series

PhMT was applied to two dental implant cases using subepithelial connective tissue grafting to increase peri‐implant keratinized tissue. These cases demonstrated that when PhMT was used in either a reactive or proactive manner, the keratinized tissue improvement can support long‐term peri‐implant health.

Conclusion

PhMT can prevent further gingival recession and provide a more stable environment conducive to maintaining peri‐implant health.
