Source of Metal Ions on Raw Cotton Fibers and their Influence on Dyeing
Authors: Fortier Chanel Angelique , Delhom Christopher , Dowd Michael K.
Published: March 2021

This work reports on two debated points related to the metal content of cotton fiber and its influence on processing. The first issue is if the metal levels of raw fibers are naturally deposited during fiber development or if the levels are influenced by weathering and harvesting conditions present after boll opening. This was tested by harvesting bolls just as they were opening and after the opened bolls were allowed to field age. The second issue relates to the importance of metal levels on fiber dyeability. Results indicate that the metal levels of newly-opened cotton were not appreciably different from those of aged cotton bolls and that the fiber metal levels after scouring and bleaching had little correlation with dye uptake. Additionally, some metal levels exceeded those previously reported and the environment appeared to have a stronger influence on fiber Ca and Mg levels than did cultivar differences.
Obraz Chin w eurazjatyckim projekcie Borisa Pilniaka: od wyobrażonego do dokumentarnego
Authors: Zhang Hui
Published: March 2021

Artykuł omawia sposób przedstawiania i opisywania Chin w dziełach Borisa Pilniaka. Autor stawia tezę, iż twórczość fikcyjna i dzienniki podróżne Pilniaka reprezentują dwa podejścia w literackiej reprezentacji Chin: wyobrażone [imaginary] i dokumentarne [documentary]. Elementem łączącym owe podejścia jest fundamentalna dla pisarza wizja eurazjatycka, którą z jednej strony można postrzegać jako dziedzictwo uniwersalistycznej postawy rosyjskiej tradycji modernistycznej, a z drugiej jako odpowiedź na kryzys tożsamości narodowej, który wyrasta z ówczesnych realiów geopolitycznych. Wyobrażenia Pilniaka na temat Chin miały charakter produktu ubocznego wyobraźni poetyckiej w dziełach napisanych przed 1922 rokiem. Tam kontynuowany był palimpsestowy proces wpisywania mitu chińskiego w rosyjskie środowisko literackie, co przekładało się na utrwalenie pojęciowej internalizacji „Chin” w kształtującej się po swojemu Rosji. Przykładem jest obraz „Kitaj-gorodu” w powieści Nagi rok, który generował różne symboliczne znaczenia Chin. Od roku 1922 wariacje narracyjnej scenerii w prozie Pilniaka odzwierciedlały wpływ ówczesnych wydarzeń na obsesyjne myśli autora dotyczące historycznego związku Rosji i Azji. Wielkie znaczenie dla Pilniaka miała jego wyprawa do Chin w 1926 roku, której rezultatem jest Kitajskij dniewnik (Dziennik chiński). Państwo chińskie staje się tam punktem odniesienia rosyjskiej autorefleksji, socjopolitycznych i ideologicznych wahań. Łącząc wyobrażenie historii z komentarzem na temat rzeczywistości, Pilniak, w różnych sposobach przedstawiania Chin, pragnął zobrazować zmieniającą się tożsamość Rosji, zarówno z jej mitologizowanej przeszłości, jak z i uwydatnionej teraźniejszości.

Czytać między przekładami. Rzecz Czarnoleska Juliana Tuwima w języku włoskim
Authors: Wanicka Marta
Published: March 2021

The aim of the article is to draw attention to the value of a translation series as an interpretation tool. Its subject is the translation series consisting of five Italian translations of Julian Tuwim’s Rzecz Czarnoleska (The Czarnolas affair). The key to the analysis is the double reference to Polish Renaissance and Romanticism by allusions to Jan Kochanowski and Cyprian Kamil Norwid. The linguistic and cultural challenges have been overcome by the translators by means of different compensation strategies singled out and commented on in the article.
„Wędrowiec-dantofil” w rodzinnej Italii. Stanisław Vincenz a włoska tradycja artystyczna
Authors: Żmidziński Jakub
Published: March 2021

The article is the first attempt at a holistic view of Stanisław Vincenz’s relationship with Italian culture. Since his youth, Vincenz would visit the Italian Peninsula travelling to Venice and, already as an emigrant after World War II, made a few visits to Naples and Tuscany. These journeys resulted in numerous comments included in his essays on Dante Alighieri, as separate overview Z perspektywy podróży (From a traveller’s perspective) and List z Neapolu. Dialog z Czesławem Miłoszem (A letter from Naples. A dialogue with Czesław Miłosz). Italian journeys, interest in Dante and Italian culture (architecture, painting, folk rituals) brought numerous Italian motifs in the tetralogy Na wysokiej połoninie (On a high mountain pasture). The key element is included in volume II, Zwada (Conflict), which describes a group of loggers cutting down trees in a primeval Carpathian forest. In this part, a young Italian dies and is buried after a Hutsul funeral ritual which is not understood by the foreigners. The analysis of the abovementioned motifs shows how important Italian culture was to Vincenz, also in a very personal sense, given the Vincenz family’s distant Venetian roots. One may even claim that for the writer, Italy was almost a family land. Personifying the European spirit, Italy was his “broader” homeland.
Maska czy gęba? Operetka Witolda Gombrowicza w kontekście komedii dell’arte
Authors: Bąkowska Nadzieja
Published: March 2021

The article is an attempt at placing Operetka (Operetta) in the context of commedia dell’arte by comparing the basic structural and ideological characteristics of Witold Gombrowicz’s drama with the key traits of the commedia dell’arte genre. The author of Ferdydurke, who coined the phrase przyprawiać (komuś) gębę (put the screws to someone’s mug), brings to the grotesque distortion any manifestations of form domination both in life and in art. Ironically, it is the elements of Operetka, related to commedia dell’arte – a thoroughly conventionalised and schematised genre, that become the tool for a sort of removal of mask or mug. Given the mask, protagonists are given “a mug”, and cannot be themselves, they can only be what is allowed by the mask they were given and so they become its prisoner, in a way. The only antidote to “the mug” is nudity that frees one from any mask that forces them to play the designated roles. The article aims to present the relationship between Operetka and the commedia dell’arte genre, with particular emphasis on analysing the Gombrowicz’s concept of form against the convention of mask and costume in the commedia dell’arte, and on the “nudity” vs. “mask” opposition that focuses the drama’s main artistic and existential issues, while it is also precisely the point where the relationship between Gombrowicz’s work and Italian commedia dell’arte is seen most clearly.
Geotechnical profiling of a surface mine waste dump using 2D Wenner–Schlumberger configuration
Authors: Supandi Supandi
Published: March 2021

Mapping the subsurface in slope stability analysis of disposal areas is difficult, especially the disposal layering materials that are assumed to be homogeneous instead of their real conditions. Moreover, the hoarding activities on high slope form layers based on the nature of the rock mechanics with large materials or boulders rolling down to the toe of the slope, while small ones are held at the top. Each layer formed, however, has certain geotechnical characteristics. The aim of this study is to determine the profiling of disposal material using a geoelectrical method known as Wenner–Schlumberger configuration with a line length of 450 m and also to find the resistivity value for mine waste materials based on an empirical number, which is a number that is obtained from the result reading compared to the actual condition in the field. The study was conducted on an in-pit dump with an estimated height of 150 m and a thickness of 50 m, and the data obtained were processed using RES2DINV software. The results showed that the subsurface cross-section has three layers consisting of bedrock with a resistivity of 50–70 Ωm, contact zone with 30–50 Ωm, and disposal material layer with 1–30 Ωm, which can be used for the slope stability analysis. This concept is very helpful for the geotechnical analysis on high mine waste dumps or sloping basement zone. This study focuses on the resistivity value for waste dump materials, which has not been clearly mentioned in the previous studies.

Our results show a remarkable improvement in the convergence of the results when compared with exact solutions.
Euxanthone inhibits traumatic spinal cord injury via anti-oxidative stress and suppression of p38 and PI3K/Akt signaling pathway in a rat model
Authors: Yao Rubin , Ren Lirong , Wang Shiyong , Zhang Ming , Yang Kaishun
Published: March 2021

Background

Owing to neurite promoting, antioxidant and anti-inflammatory effects of Euxanthone (Eux), the investigation was aimed to probe the neuroprotective efficacy of Eux against traumatic spinal cord injury (t-SCI) in rats and whether Eux can improve neuropathic function in t-SCI.

Method

Sprague-Dawley (SD) rats were randomized in – Sham, t-SCI, Eux30, and Eux60 (t-SCI + 30 and 60 mg/kg respectively). Animals with compression force-induced t-SCI were subjected to estimation of locomotor functions. Spinal cord water content and Evans blue (EB) effusion were determined for quantifying edema and intactness of the spinal cord. Oxidative stress and immunochemical markers were quantified by ELISA and western blotting.

Results

Findings revealed that Eux60 group animals had greater Basso, Beattie, and Bresnahan (BBB) and (incline plane test) IPT score indicating improved locomotor functions. There was a reduction in the spinal edema and water content after Eux treatment, together with lowering of oxidative stress markers. The expression of IL-6, IL-12, IL-1β, caspase-3, RANKL, TLR4, NF-κB, p-38, PI3K, and Akt in spinal cord tissues of t-SCI-induced rats was lowered after Eux treatment.

Conclusion

Overall, the investigation advocates that Eux attenuates t-SCI and associated inflammation, oxidative damage, and resulting apoptosis via modulation of TLR4/NF-κB/p38 and PI3K/Akt signaling cascade.
Realization of System Robustness by Clustering to Predict New Product Performance Levels
Authors: Eddy Douglas , Krishnamurty Sundar , Grosse Ian
Published: March 2021

Final test metrics that evaluate product system performance usually depend upon numerous variables, such as dimensions or other characteristics of parts and assemblies. Many product systems are expensively comprised of numerous parts. Therefore, during new product system development, the challenge becomes how to rapidly learn estimated system results from combinations of many variables at the smallest possible sample size to minimize cost and improve product quality. In this work, we introduce a fundamental Vector-Based Clustering technique to predict a cluster range of system test results for comparison to other machine learning techniques in a commercial software tool. This work expands to include two additional techniques that account for significance among many variables. All three of these techniques were tested and compared to the machine learning algorithm from a commercial tool best suited for each training set from a high dimensional open-source data set representative of manufacturing system data. These case study results show improvement in predictive accuracy over many prevalent machine learning techniques at small sample sizes. Furthermore, since a best-suited machine learning technique is selected by trial and error for each training set, the computational time is significantly improved as well.
Antihypertensive Drugs (АCE- Inhibitors/ Beta- Blockers) and Chronic Infections as Potential Triggers for the Spontaneously Development of Small Plaque Parapsoriasis ?!
Authors: Tchernev Georgi , Wollina Uwe , Stavrov Konstantin , Temelkova Ivanka
Published: March 2021

Background: There are different literature data according to which small plaque parapsoriasis (SPP) and guttate parapsoriasis could be considered as part of the various clinical forms of MF. However, there are no literature data that compare different control groups of patients (receiving/ not taking antihypertensive medication) and the two important possibilities deriving from it, namely: 1) that certain drug forms could be inducers of parapsoriasis and 2) that other drug forms could potentiate the transformation of existing parapsoriasis into T-cell lymphoma. We describe a case of possible infectious and / or drug-induced SPP by discussing an important, albeit currently hypothetical link to the drug mediated cancerogenesis. Case report: We present a 39-year-old man with a disseminated eruptive erythemo-papulo-squamous rash, localized on the skin of the trunk and extremities. According to anamnestic data, skin symptoms date back to about 1 month when the patient was hospitalized in the ENT compartment for severe throat pain. Primary empirical antibiotic therapy with clindamycin 4x 600mg/ daily i.v was performed on a regimen and partial remission was achieved. Immediately afterwards there was a resumption of symptoms and the additional occurrence of skin lesions. From the conducted tests, the presence of acute tonsillopharyngitis, focal infection of dental origin and elevated antistreptolysin titer was found. In parallel, the patient receives antihypertensive therapy (ACE inhibitor and beta blocker) on the occasion of arterial hypertension. There was a suspicion for infectious and / or drug-triggered psoriasis gutata, as the subsequent histological study showed evidence of small plaque parapsoriasis. Conclusion: Although there are a number of literature data on the relationship between antihypertensive drugs and their pro-or anticancerogenic action against various types of tumors, there is currently no data available to compare the existing risk of developing T- cell lymphoma in patients with SPP and concomitant cardiac therapy with ACE inhibitors and beta blockers. We present a patient with triple histologically verified small plaque parapsoriasis and we are discussing a completely new pathogenetic element: triggering in the framework a possible chronic infection and systemic antihypertensive therapy. The selected retrospective or prospective analysis of wider groups of patients with chronic infections / systemic antihypertensive medication as well as proven T cell lymphomas could provide clarity with respect to the shared by us observations in single patients.

Published: March 2021

Background: Atopic Dermatitis (AD) is a chronic inflammatory skin disease that causes functional disruption of the skin barrier. We previously found that ethanol Extracts of Mallotus Philippinensis Bark (EMPB) promoted migration of mesenchymal stem cells and improved wound healing probably through anti-inflammatory action. However, direct evidence of the anti-inflammatory effect of EMPB and the underlying mechanisms of this action remain unknown. In the present study, we evaluated whether EMPB has an effective action on anti-inflammation using an in vitro and in vivo model. We found that topical application of EMPB improved house dust miteinduced AD-like skin inflammation in NC/Nga mice. In addition, EMPB significantly inhibited various kinds of inflammatory mediators such as interleukin-1ß, inducible nitric oxide synthases, and nuclear factorkappa B in lipopolysaccharide-stimulated macrophage cells. Moreover, EMPB exhibited marked radical scavenging ability. Taken together, these results suggest that EMPB may be useful in the treatment of skin inflammatory diseases such as AD.

About 15 years duration of the finding, as the lesion being suspected clinically and dermatoscopically for cutaneous melanoma. The patient was initially treated with a surgical margin of 0.5 cm in all directions, with a tumor thickness of 3 mm immediately established afterwards. The subsequent surgical session 9 days later (as recommended by the AJCC) included: 1) removal of 4 sentinel lymph nodes: 3 of them located infrascapularly and one axillary apically to the left and 2) reexcision of the primary surgical wound with a safety margin of 1.5 cm in all directions. Lymph node involvement data are lacking and the patient is staged as IIA (T3a N0M0).
An Implanted Vestibular Prosthesis Improves Spatial Orientation in Animals with Severe Vestibular Damage
Authors: Karmali Faisal , Haburcakova Csilla , Gong Wangsong , Della Santina Charles C. , Merfeld Daniel M. , Lewis Richard F.
Published: March 2021

Gravity is a pervasive environmental stimulus, and accurate graviception is required for optimal spatial orientation and postural stability. The primary graviceptors are the vestibular organs, which include angular velocity (semicircular canals) and linear acceleration (otolith organs) sensors. Graviception is degraded in patients with vestibular damage, resulting in spatial misperception and imbalance. Since minimal therapy is available for these patients, substantial effort has focused on developing a vestibular prosthesis or vestibular implant (VI) that reproduces information normally provided by the canals (since reproducing otolith function is very challenging technically). Prior studies demonstrated that angular eye velocity responses could be driven by canal VI-mediated angular head velocity information, but it remains unknown whether a canal VI could improve spatial perception and posture since these behaviors require accurate estimates of angular head position in space relative to gravity. Here, we tested the hypothesis that a canal VI that transduces angular head velocity and provides this information to the brain via motion-modulated electrical stimulation of canal afferent nerves could improve the perception of angular head position relative to gravity in monkeys with severe vestibular damage. Using a subjective visual vertical task, we found that normal female monkeys accurately sensed the orientation of the head relative to gravity during dynamic tilts, that this ability was degraded following bilateral vestibular damage, and improved when the canal VI was used. These results demonstrate that a canal VI can improve graviception in vestibulopathic animals, suggesting that it could reduce the disabling perceptual and postural deficits experienced by patients with severe vestibular damage.

SIGNIFICANCE STATEMENTPatients with vestibular damage experience impaired vision, spatial perception, and balance, symptoms that could potentially respond to a vestibular implant (VI). Anatomic features facilitate semicircular canal (angular velocity) prosthetics but inhibit approaches with the otolith (linear acceleration) organs, and canal VIs that sense angular head velocity can generate compensatory eye velocity responses in vestibulopathic subjects. Can the brain use canal VI head velocity information to improve estimates of head orientation (e.g., head position relative to gravity), which is a prerequisite for accurate spatial perception and posture? Here we show that a canal VI can improve the perception of head orientation in vestibulopathic monkeys, results that are highly significant because they suggest that VIs mimicking canal function can improve spatial orientation and balance in vestibulopathic patients.
Reduced Repetition Suppression in Aging is Driven by Tau–Related Hyperactivity in Medial Temporal Lobe
Authors: Adams Jenna N. , Maass Anne , Berron David , Harrison Theresa M. , Baker Suzanne L. , Thomas Wesley P. , Stanfill Morgan , Jagust William J.
Published: March 2021

Tau deposition begins in the medial temporal lobe (MTL) in aging and Alzheimer's disease (AD), and MTL neural dysfunction is commonly observed in these groups. However, the association between tau and MTL neural activity has not been fully characterized. We investigated the effects of tau on repetition suppression, the reduction of activity for repeated stimulus presentations compared to novel stimuli. We used task-based functional MRI (fMRI) to assess MTL subregional activity in 21 young adults (YA) and 45 cognitively normal human older adults (OA; total sample: 37 females, 29 males). AD pathology was measured with position emission tomography (PET), using18F-Flortaucipir for tau and11C-Pittsburgh compound B (PiB) for amyloid-β (Aβ). The MTL was segmented into six subregions using high-resolution structural images. We compared the effects of low tau pathology, restricted to entorhinal cortex and hippocampus (Tau– OA), to high tau pathology, also occurring in temporal and limbic regions (Tau+ OA). Low levels of tau (Tau– OA vs YA) were associated with reduced repetition suppression activity specifically in anterolateral entorhinal cortex (alEC) and hippocampus, the first regions to accumulate tau. High tau pathology (Tau+ vs Tau– OA) was associated with widespread reductions in repetition suppression across MTL. Further analyses indicated that reduced repetition suppression was driven by hyperactivity to repeated stimuli, rather than decreased activity to novel stimuli. Increased activation was associated with entorhinal tau, but not Aβ. These findings reveal a link between tau deposition and neural dysfunction in MTL, in which tau-related hyperactivity prevents deactivation to repeated stimuli, leading to reduced repetition suppression.

SIGNIFICANCE STATEMENTAbnormal neural activity occurs in the medial temporal lobe (MTL) in aging and Alzheimer's disease (AD). Because tau pathology first deposits in the MTL in aging, this altered activity may be due to local tau pathology, and distinct MTL subregions may be differentially vulnerable. We demonstrate that in older adults (OAs) with low tau pathology, there are focal alterations in activity in MTL subregions that first develop tau pathology, while OAs with high tau pathology have aberrant activity throughout MTL. Tau was associated with hyperactivity to repeated stimulus presentations, leading to reduced repetition suppression, the discrimination between novel and repeated stimuli. Our data suggest that tau deposition is related to abnormal activity in MTL before the onset of cognitive decline.

An Instant Update on Viruses
Authors: Simon Uwe K.
Published: March 2021

The current COVID-19 pandemic shows how little many people know about viruses. Yet apart from COVID-19, the world has observed epidemic spread of another SARS virus, of the Ebola virus, and of the Zika virus during the last two decades. The human immunodeficiency virus (HIV) is still one of the most dangerous viruses worldwide. Some types of the human papillomavirus (HPV) are the main cause of cervical cancer. Cases of measles, also caused by a virus, increase in numbers due to lack of access to or refusal of vaccination. Furthermore, there is the widespread belief that viruses are similar to bacteria and may thus be fought off with antibiotics. Yet viruses have no metabolism. Thus, antibiotics cannot work against them, but may instead cause more harm than help, given side effects such as killing beneficial bacteria (e.g., in the intestine). Second, misuse of antibi-otics is one key factor in the evolution of antibiotic-resistant bacterial strains – a strong public health issue nowadays. This article informs readers what viruses are, how they are distinct from bacteria, how they may have evolved, and how diseases they cause may be prevented. Additionally, insights from studies concerning students’ virus-related knowledge are summarized.
An Interactive & Cooperative Activity for Exploring Animal Systematics Using Cards & String
Authors: Brown Christopher G.
Published: March 2021

Students sometimes struggle to organize complex concepts and visualize the connectedness of hierarchical groups, yet much of the biological sciences depends on ranking, ordering, or grouping of information. Diagnosing disease, converting units, and evolutionary relationships all follow stepwise ranking of groups of information. This article presents a cooperative, low-stakes, inexpensive method for novice students to organize hierarchical information. As an example, students work together placing and rearranging animal cards according to taxonomic and evolutionary relationships along a string using shared characteristics. The cards provided address Next Generation Science Standards pertaining to inheritance/variation (LS3) and unity and diversity (LS4). I provide a detailed description of the activity as well as the tools needed to perform this lesson.

Focusing on our interactions with visual art as posthuman performance, this piece explores how Jane Bennett’s “vibrant materiality” moves us into a radical relationality with art and processes of grief. Performance studies’ enduring plumb into the deep ecology of body-page-body-stage makes us particularly equipped to see what else we might know of being in semantic-somatic multimatter knowing.
Micro-Protests as Co-cultural Communicative Practice
Authors: Orbe Mark P.
Published: March 2021

In this article, I utilize phenomenologically-based creative nonfiction to present a case study of what micro-protest looks like for an African American faculty member working in a predominantly white university. Drawing from observations and informal information-gathering techniques over a 20+ year period, I present a layered account to share snippets from a larger narrative that vividly capture the nuanced ways co-cultural group members navigate predominantly white organizational spaces in the margins. Ultimately, I introduce the various ways micro-protest—as a new conceptualization of co-cultural practice—is enacted to achieve the preferred outcome of separation. I conclude with a brief discussion of how this scholarly endeavor contributes to co-cultural research and theorizing.

Academia can be a hostile environment for Black women. Our research team leveraged Black feminist research praxis to produce new knowledge countering conceptions of Black women students and faculty as people who are unintelligent, produce superfluous work, and worthy of being ignored. In order to locate spaces for healing, mentorship, and validation, we engaged in a collaborative autoethnography to co-narrate our experiences while conducting a study for, by, and about Black women. Re-purposing tools from Black feminist thought, critical autoethnography, and collaborative autoethnography enabled us to write ourselves into existence, countering damaging narratives and subverting the harm inflicted by the institution.

Abstract

Pyramid House in Palembang is one of the works of art that is still very interesting to be researched today. The problem raised in this study aims to analyze the cultural message of the Pyramid House in Palembang. The method used is a qualitative method with a case study research design. The data collection techniques include observation, interviews, and document study. The results showed that in the manufacture of the Pyramid house, the main construction of traditional buildings used wood construction and a stilt system. The foundation used the construction of piles, the walls used boards, the roof used a leaf or shingle roof. The core parts consisted of the roof of the house, the door, the window, the stairs, and the floor of the house. In general, the typical architectural form of the Pyramid House, namely, the roof was shaped like a severed pyramid. Besides, the uniqueness of the house located in its multi-storey shape (kijing) and the walls were made of wood shaped like planks. Then related to the house name Pyramid, it contained two special meanings, namely, Five and Gold. The word five means the number five, while gold means the precious metal of great value. This is also a symbol of the function of the Pyramid house.

Published: March 2021

Insulin release index (IRI) based on 72-h fasting test has been used for the definitive diagnosis of insulinoma; however, hospitalization and subsequent costs contribute to the disadvantage of IRI. Therefore, a simple and cost-effective screening procedure for the diagnosis of insulinoma for outpatients are crucially needed. Continuous glucose monitoring (CGM) has been widely used for monitoring high level of glucose in diabetic patients. The aim of the study is to determine the potential contribution or implementation of CGM in the screening of the insulinoma. We performed a single-center prospective study with the demographics and laboratory data including 28 patients with the pathological diagnosis of insulinoma and 25 patients with functional hypoglycemia as control group. The analysis showed that areas under the receiver operating characteristic (ROC) curve of coefficient of variation (CV) was 0.914. The CV cutoff point was 19% with the Youden 62.1%, the corresponding sensitivity and specificity were 82.1 and 80%, respectively. In patients with CV greater than the median, more than 60% of insulinomas were located in the head of the pancreas; most Ki-67 values were more than 2% and when compared with the group with CV smaller than the median, the average tumor size was 2.7 times larger. In conclusion, CGM can be used as a valuable tool in not only monitoring high glucose levels in diabetic patients but also identifying the etiology of insulinoma. CV greater than 19% can be highly effective for the screening of insulinoma in outpatients.
Neuritin inhibits astrogliosis to ameliorate diabetic cognitive dysfunction
Authors: Zhang Zuo , Zhou Hongli , Zhou Jiyin
Published: March 2021

Earlier, it was shown that reversing the downregulation of neuritin expression in the brain improves central neuropathy in diabetic rats. We investigated the protective mechanism of neuritin in diabetic cognitive dysfunction via astrocytes. Further, the impact of the overexpression of neuritin in the cortex and the hippocampus on diabetic cognitive dysfunction and astrogliosis in type 2 diabetic (db/db) mice was assessed. Antagonists were used to inhibit the JAK2/STAT3 signaling pathway in U-118MG, an astrocyte cell line. Immunofluorescence, Western blotting, and real-time PCR were performed. Neuritin overexpression in the hippocampus of db/db mice significantly ameliorated cognitive dysfunction, hippocampal neuronal impairment, and synaptic plasticity deterioration, and inhibited astrogliosis and the JAK2/STAT3 signaling pathway in the hippocampus. Neuritin suppressed the JAK2/STAT3 signaling pathway to inhibit lipopolysaccharide-induced gliosis in U-118MG cells. It was observed that neuritin regulates the JAK2/STAT3 signaling pathway in astrocytes to inhibit astrogliosis and improve diabetic cognitive dysfunction.

Neste traballo tratamos o valor dos Recursos Humanos Internacionais como fontepotencial de vantaxe competitiva para as organizacións. Sobre a base dun estudo realizado entre150 expatriados españois, analizamos os seus principais resultados. Comprobamos se o tempointroduce diferenzas significativas nestes resultados, e tamén se son efectivamente medidos polasorganizacións. Ademais, a partir dunha enquisa de 330 expatriados auto-iniciados suxerimos que osque abandonan voluntariamente o noso país na procura de oportunidades profesionais obteñen omesmo tipo de logros. Os datos do noso estudo confirman que as persoas que se atopan en postos noestranxeiro perciben a adquisición de habilidades internacionais e a mellora de competenciasprofesionais, que poden determinar o diferencial competitivo para as súas organizacións. Asímesmo, os que se atopan no estranxeiro na procura dunha oportunidade laboral ou dedesenvolvemento profesional obteñen idénticos resultados, o que suxire que existe unha bolsa deprofesionais altamente cualificados con talento disperso que poderían significar para as empresas amellora de posibilidades de expansión internacional, e para o país a inversión de fuga de talento que,a longo prazo, pode derivar na descapitalización. O tempo mellora os resultados nos dous casos.

OBJECTIVES:

Misdiagnosis of acute and chronic otitis media in children can result in significant consequences from either undertreatment or overtreatment. Our objective was to develop and train an artificial intelligence algorithm to accurately predict the presence of middle ear effusion in pediatric patients presenting to the operating room for myringotomy and tube placement.

METHODS:

We trained a neural network to classify images as “ normal” (no effusion) or “abnormal” (effusion present) using tympanic membrane images from children taken to the operating room with the intent of performing myringotomy and possible tube placement for recurrent acute otitis media or otitis media with effusion. Model performance was tested on held-out cases and fivefold cross-validation.

RESULTS:

The mean training time for the neural network model was 76.0 (SD ± 0.01) seconds. Our model approach achieved a mean image classification accuracy of 83.8% (95% confidence interval [CI]: 82.7–84.8). In support of this classification accuracy, the model produced an area under the receiver operating characteristic curve performance of 0.93 (95% CI: 0.91–0.94) and F1-score of 0.80 (95% CI: 0.77–0.82).

CONCLUSIONS:

Artificial intelligence–assisted diagnosis of acute or chronic otitis media in children may generate value for patients, families, and the health care system by improving point-of-care diagnostic accuracy. With a small training data set composed of intraoperative images obtained at time of tympanostomy tube insertion, our neural network was accurate in predicting the presence of a middle ear effusion in pediatric ear cases. This diagnostic accuracy performance is considerably higher than human-expert otoscopy-based diagnostic performance reported in previous studies.

First Report on Pea Seed-borne Mosaic Virus in Hungary
Authors: Almási A. , Boros R. , Salánki K. , Barna B.
Published: March 2021

One of the most important diseases of pea is caused by Pea seed-borne mosaic virus (PSbMV), which has a relatively wide host range. Since there are few varieties with resistance against the virus, and spraying insecticides is not very effective, the determination of the disease and the pathogen in the seeds is very important. Inoculum prepared from pea seeds showing typical virus symptoms caused very mild symptoms on Chenopodium amaranticolor and C. quinoa, but several chlorotic/necrotic lesions on bean (Phaseolus vulgaris) cv. Scarlet, and systemic symptoms with mosaic and curling of top leaves on bean cv. Maxidor. The detection of the virus was carried out by PCR using universal primers and virus sequence analysis. According to the phylogenetic analysis the PSbMV isolate identified in Hungary belongs to the pathotype P1 and associated with the cluster 2 isolates.
