Az OSZK Cod. Lat. 423-as kódex „poeta christianus”-a
Authors: Bolonyai Gábor
Published: November 2021

A Cod. Lat. 423 nagy valószínűséggel azon corvinák egyike, amelyek eredetileg Janus Pannonius könyvtárába tartoztak.1 A vegyes tartalmú kézirat 1v–9v lapjain egy hexameterben megírt, 473 soros tanköltemény olvasható az istenek származásáról. A mű egy másik példányát a bécsi Nationalbibliothek ÖNB Cod. 250 jelzetű kódexe őrzi. Szerzőjét „ismeretlen” vagy „keresztény költőként” tartja számon az osztrák és magyar kodikológiai szakirodalom. Az utóbbi megjelölés a bécsi Hofbibliothek 1835-ben megjelent Endlicher-féle katalógusában olvasható először,2 s innen öröklődött át a Corvina-katalógusokba, előbb Fógel József, 3 majd Csapodi Csaba,4 végül Madas Edit5 listájába is. A bécsi Nationalbibliothek legutóbbi,elektronikus katalóguscédulájának elkészítője egyszerűen ’unbekannt’-nak nevezi a költőt, ahogy az OSZK digitális Corvina-gyűjteményében is ismeretlen szerzőként tartják számon.

A tiszaeszlári vérvád és a nyíregyházi per az élclapok hasábjain
Authors: Tamás Ágnes
Published: November 2021

Az elemzés forrása, időintervalluma

A nyíregyházi per végítéletének kimondása előtt jegyezte le az egyik elemzésre kerülő bécsi vicclap, a Figaro szerzője, hogy „a magyar glóbusz uralja most az egész világtörténelmet”, utalva arra, hogy Európa-szerte nagy érdeklődést váltott ki a tiszaeszlári vérvád és az azt tárgyaló nyíregyházi per. A forrásbázis nagyobb részét képező magyarországi élclapok a per eseményeit pontosan követték, a megelőző hét történéseire reagáltak humoros-gúnyos cikkeikkel és karikatúrákkal, így ha egymás után vizsgálnánk a lapszámokat, a per és a hozzá kapcsolódó helyszínek rajzolódnának ki előttünk – egy pártpolitikától sem független görbe tükrön keresztül. Elöljáróban megállapíthatjuk, hogy az izraelita Ágai Adolf által szerkesztett, az antiszemita hangulat ellen fellépő, kormánypárti Borsszem Jankón kívül a másik két elemzett magyar ellenzéki lap – a Bolond Istókés az Üstökös – nyíltan antiszemita nézeteket hangoztatott, míg a Karl Sitter által életre hívott liberális Figaro magán a tényen gúnyolódott, hogy az eljárás a zsidók ellen egyáltalán elkezdődhetett. A bécsi élclap nem követte napról napra az eseményeket, de több számában is foglalkozott a vérváddal, majd üdvözölte a felmentő ítéletet.

A review on Cone Beam Computed Tomography in dentistry
Authors: Nimeshkumar Patel , Ekta Mistry
Published: November 2021

Introduction: Cone Beam Computed Tomography (CBCT) has transformed the manner in which radiological evaluation is performed. Methods: This article discusses the different aspects of CBCT, common dental applications of CBCT for diagnosis and treatment in different dental specialties from the current literature. Results: CBCT has been widely accepted into different dental practices. The main reasons are the decreased size, low cost, less exposure to radiation as compared to computed tomography. CBCT enables the three dimensional assessment of the region of maxilla, mandible, cranium, and associated structures. Conclusions: Dentists and dental specialists can utilize three dimensional radiography- CBCT for a comprehensive diagnosis. CBCT can also help in identifying the structures such as root canals, bifurcated canals, supernumerary teeth, impacted teeth in different planes and thus are a valuable tool for dental treatment planning.
Hunting heraldry of the Volyn and Kyiv regions in the 16th – early 17th centuries
Authors:   Taras Shevchenko national University of Kyiv, Kravchenko Nadiia
Published: November 2021

The article is devoted to the subjects and symbolism in the hunting heraldry of the Volyn and Kyiv regions in the 16th – early 17th centuries. Among the innovations of this time period is the appearance of atypical imagery in Ukrainian heraldry, namely that of wild animals and hunting horns. The author analyzes the well-known coats of arms associated with hunting, their prevalence and probable reasons for their obscurity in these areas compared to the Kingdom of Poland. In the early modern period, nobility used heraldic signs and legends to emphasize their ancient origins, land tenureship and political influence. The appearance of wild animals on Ruthenian coats of arms was symptomatic of the spread of Western heraldic tradition and hunting culture as such. There were multiple instances of symbiosis between the Ruthenian heraldic tradition and Western templates, the most striking of which is the “Korczak” coat of arms. It is believed that the mantling in the form of a dog of the Hungarian Vizsla breed, depicted sitting in a bowl is of Hungarian origin, but the image of the shield (an "escutcheon") of this coat of arms is actually Ruthenian, interpreted as three belts, logs or rivers. Less prolific than the “Korczak” coat of arms and its variations were the addendum of Western heraldic attributes to the old coats of arms, such as that of hunting horns. Most of the Western-style coats of arms known or relatively known in these areas belonged to those granted to the Grand Duchy of Lithuania nobility in 1413. Many of them were distributed mainly among the small gentry of Polish origin or Galician immigrants. Instead, in the Volyn and Kyiv regions, the gentry preferred their own historical coats of arms, created on the basis of ancient territorial symbolism. Conceivably, their commitment to ancient heraldic tradition was intended to accentuate their Ruthenian identity.
Precise Locating of the Great 1897 Shillong Plateau Earthquake Using Teleseismic and Regional Seismic Phase Data
Authors: Subedi Shiba , Hetényi György
Published: November 2021

Pinched between the Eastern Himalaya and the Indo-Burman ranges, the Shillong Plateau represents a zone of distributed deformation with numerous visible and buried active faults. In 1897, a great (magnitude 8+) earthquake occurred in the area, and although a subsurface rupture plane has been proposed geodetically, its epicenter remained uncertain. We gathered original arrival time data of seismic waves from this early-instrumental era and combined them with modern, 3D velocity models to constrain the origin time and epicenter of this event, including uncertainties. Our results show that the earthquake has taken place in the northwest part of the plateau, at the junction of the short, surface-rupturing Chedrang fault and the buried Oldham fault (26.0°N, 90.7°E). This latter fault has been proposed earlier based on geodetic data and is long enough to host a great earthquake. Rupture has most likely propagated eastward. Stress change from the 1897 earthquake may have ultimately triggered the 1930 M 7.1 Dhubri earthquake, along a fault connecting the Shillong Plateau with the Himalaya.
Profiles of semantic knowledge impairment
Authors:   , Cloud Blaine Scott , Spiers Mary Virginia
Published: November 2021

This research aims to elucidate relationships between knowledge stored in the brain and possible neuroanatomical substrates. It attempts to demonstrate that knowledge is distributed and can be divided phenomenologically and anatomically into perceptual and functional-associative components. Patients suffering from Alzheimer's Disease, Parkinson's Disease with dementia, and Ischaemic Vascular Disease served as experimental participants. Semantically impaired participants were divided into two groups according to the nature of their impairments: (1) primary breakdown of semantic structure, versus (2) primary inability to access otherwise intact semantic knowledge stores. Participants were administered a questionnaire that probed their knowledge of perceptual and functional-associative attributes of animals and tools. A 2 (group) x 2 (category) x 2 (attribute) analysis of variance demonstrated that patients with "knowledge degradation" were more impaired overall, and more impaired specifically on animal information as compared to "access" patients. It was predicted that the access patients would be impaired on associative-functional and tool information, but these predictions were not supported. The second hypothesis was that knowledge of animate objects is predicated upon perceptual information whereas knowledge of inanimate objects relies more heavily upon functional information. This hypothesis was not supported. Semantic dimensions were correlated with magnetic resonance imaging (MRI) indices. It was hypothesized that perceptual-animal knowledge would be dependent upon the integrity of posterior temporal cortex and functional-tool knowledge upon frontal lobe white matter tracts. However, semantic-neuroanatomic correlations did not reach significance. These findings support the notion that the brain's representations of knowledge are differentiated according to category membership and attribute type. Knowledge of tools and of functional attributes appears to be more impervious to loss in dementia than knowledge of animals and perceptual attributes. Degradation of knowledge leads to differential impairment working with animal knowledge whereas accessing impairment does not lead to preferential processing of either animate or tool knowledge. The relation between category and attribute level knowledge remains unclear but functional and perceptual attributes may be more closely associated with each other for tools than they are for animals. This may explain why tool knowledge was found to be more impervious to neuropathology.
El túnel de la sucursal. La velocidad de una ciudad comprimida y acelerada
Authors:   Universidad Icesi, Moreno Bejarano Laura Marcela
Published: November 2021

Este libro muestra el “Túnel de la terminal” como un espacio de compresión del mundo urbano que está afuera. Una suerte de metáfora subterránea de lo que es la vida urbana de una ciudad como Cali. Un trabajo sobre un espacio micro que devela lo que es o puede ser la ciudad. Un trabajo así hecho, cobra especial importancia en una ciudad que se quiere alegre y festiva, que se proclama cada ocho días al borde del carnaval, y que se ve sometida a revisión desde un pequeño espacio, en penumbra, un recodo que no parece que pueda dar cuenta de esa “luz de nuevo cielo” de la que habla una emblemática canción [Enrique Rodríguez Caporalli].
Seismic Imaging of Active and Ancient CO2 Pathways in the Little Grand Wash Fault
Authors: Yelton Jonathan
Published: November 2021

Understanding the migration behavior of carbon dioxide (CO2) during long-term geological storage is crucial to
the success of carbon capture and sequestration technology. I explore p-wave and s-wave seismic properties across
the Little Grand Wash fault in east-central Utah, a natural CO2 seep and analogue for a long-failed sequestration
site. Travertines dated to at least 113,000 k.y. and geochemical surveys confirm both modern and ancient CO2 leakage
along the fault. Outgassing is currently focused in damage zones where the total fluid pressure may reduce the
minimum horizontal effective stress. Regional stress changes may be responsible for decadal- to millennial-scale
changes in CO2 pathways.

I identify subsurface geologic structure in the upper few hundred meters and relate surface CO2 outgassing zones
to seismic reflection and first arrival tomography data. I tie my hammer seismic results to borehole logs, geology
from outcrops, and geochemical data. I generate velocity tomograms that cross the fault zone and construct rock physics
models. I identify high porosity and/or high fracture density zones from slow seismic velocity zones. These zones match
mapped fault locations, are fully saturated, and are conduits for upward fluid/gas migration. Anomalously high seismic
velocities at the fault are consistent with ancient CO2 flow pathways. Low CO2 flux regions show seismic velocities
consistent with shallow unsaturated host rock. Studying the behavior of CO2 in this system can give insight of potential
risks in future sequestration projects.
Potentially inappropriate medications in nursing homes of iraqi elders: Pharmacists’ assessment and intervention based on 2019 beers criteria
Authors: Naqash Hussein
Published: November 2021

The number of elderly people worldwide is growing with the increasing life expectancy of the human population; in Iraq, the number of elderly people aged ≥65 years was estimated to be 1.34 million in 2019. The use of potentially inappropriate medications (PIMs) is high among older adults, which is associated with an increased risk of adverse drug reactions. This study investigated the use of PIMs among elderly nursing home (NH) residents in Iraq based on 2019 Beers criteria and the application of the criteria and intervention by pharmacists. An interventional study was conducted from January 2019 to April 2019 at 2 NHs in Baghdad, Iraq. A total of 109 NH residents aged ≥65 years that were using ≥1 daily medicine were included. Patients discharged before completion of the assessment were excluded. Patients with PIMs were using significantly more medications (5.7±3.2) than those without PIMs (2.0 ±1.46) (p<0.0001). The total number of PIMs identified according to the 2019 Beers criteria was 163; for 140 of these (85.9%), pharmacists recommended changing the prescription, with 112 (68.7%) discontinued/changed as a result for an acceptance rate of 80% by physicians. Our results indicate that the use of PIMs for the treatment of Iraqi NH residents is associated with polypharmacy. Thus, prescriptions for elderly people in Iraq with polypharmacy or multiple concurrent diagnoses should be reviewed for PIMs by pharmacists to reduce the risk of adverse events.

Use of Instagram as a Promotion Media of the Faculty Library at Gadjah Mada University
Authors: Karunia Leila
Published: November 2021

Background of the study: Libraries use social media to promote libraries for users, one of which is Instagram. Gadjah Mada University Library (UGM) and several faculty libraries have used Instagram as a promotional media, but not all are up to date.

Purpose: The purposes of this study are to identify the way the faculty library promotes through Instagram and analyze the motivation factors and obstacles faced in promoting the library through Instagram.

Method: This study was conducted at the faculty library at UGM used a thick description with a qualitative approach. Data collection techniques used are in-depth interviews, observation and literature study. This study discusses the use of Instagram as a library promotion media from librarians and staff who manage the library's Instagram.

Findings: The results of the study show that: First, seven of the eighteen library libraries at UGM were promoted through Instagram. The way the faculty library promoting on Instagram is through posting content such as documenting events, library services, promoting events, and e-resources. Second, the motivation factor of the faculty library at UGM to use Instagram as a promotion media is to adapt to the generation of users and social media used by users. The obstacle faced by most faculty libraries in using Instagram as a library promotion media is the limitations of Human Resources (HR).

Conclusion: The use of Instagram as a promotion media of faculty libraries at UGM is still not up to date. The majority of faculty libraries haven't used Instagram to promote the library. Seven faculty libraries have used Instagram but are not the same in up to date.
Differences in information source preferences by students during pre and post PSBB covid-19 pandemic
Authors: Darmawan Mochamad , Handika Cahyo , Pratama M. Didan , Al Maulana M. Aflah
Published: November 2021

Background of Study: The increasingly rapid and massive spread of the COVID-19 virus to various countries, has made the Indonesian Government implement a Large-Scale Social Restriction (PSBB) policy in order to stop the spread of the virus. This policy makes various activities, such as services in libraries, must be closed. This of course makes library users, such as students switch to using electronic information sources. Furthermore, the Government decided to start a new era habit or called the "New Normal" by living adapting to the spread of the virus.

Purpose: This research was conducted in order to review the preferences of information sources used by students after the PSBB policy.

Method. The research method used is a quantitative approach, with a descriptive type. The target population of this research are students from Surabaya. Data collection was carried out by means of a survey using a questionnaire. Then processed using the SPSS 18.0 application

Analysis. The analysis uses theory in the literature.

Results: The results showed that most of the students chose electronic information sources as their main preference. This is indicated by the results of research showing that information retrieval machines have become a popular choice both in the pre and post PSBB periods. However, comparative figures show that there are differences in several sources of information in the two periods.

Conclusion: Since the PSBB, most students have experienced changes in their preferences for information sources.
Utization of Instagram as a Library’s Digital Marketing
Authors: Masyithah Deby Claudia
Published: November 2021

Background of the study: Instagram is one of the most popular social media today, so Instagram is very effective as a media for library promotion. Through Instagram, users who like social media can view photos of library collections or view library images. Through Instagram, librarians can easily disseminate information, offer library services, promote libraries or communicate directly with users.

Purpose: The purpose of this study will be to analyze how the use and influence of Instagram as a digital marketing library facility

Method: This research uses qualitative method. Informants from this study were UGM S-1 students and UIN Sunan Kalijaga who are still actively studying and have an Instagram account.

Findings: The results of this study are that there are still many students who do not know of the existence of a library Instagram account either at UGM or UIN Sunan Kalijaga. Students who know and follow Instagram library accounts do not always access information from their Instagram account. They prefer to come directly to the library or visit the official library website if you want to find out information about the library. This is because the content on the library's Instagram account is unattractive and does not match what is needed by students.

Conclusion: Students visit the library not because they see it from the library's Instagram account, because the content uploaded from the two Instagram accounts is dominated by photos of activities held in the library not about collections or facilities in the library.
Mathematical modeling of contact interaction of two electroelastic half-spaces (without electrode coating of surfaces) in the presence of a hard disk-like inclusion between them and pressure in the area of separation
Authors: Kirilyuk Vitaly , Levchuk Olga
Published: November 2021

Based on the use of a rigorous mathematical model that takes into account the connectivity of force and electric fields in electroelastic bodies, the contact interaction of two piezoelectric transversely isotropic half-spaces with different properties under compression (in the presence of a hard disk-shaped inclusion between them and pressure in the material separation region) was studied. The solution to the problem is obtained by representing the general solution of the static equations of the electroelasticity for a transversely isotropic body in terms of harmonic functions, followed by the construction of the boundary value problem of the electroelasticity to the consideration of the integral equation and the expansion of the desired function in a small parameter. As a special case from the constructed analytical expressions, the main parameters of the contact for two elastic transversely isotropic and isotropic half-spaces (with the inclusion between them and pressure in the separation region) are implied. Numerical results were obtained. The influence was studied of the electroelastic properties of half-spaces, the geometric dimensions of the inclusion, and loads on the parameters of the contact interaction of electroelastic bodies.
Fuzzy Clustering in Assortative and Disassortative Networks

Published: November 2021

Despite the significance of assortativity as a property of networks that paves for the emergence of new structural types, surprisingly, there has been little research done on assortativity. Assortative networks are perhaps among the most prominent examples of complex networks believed to be governed by common phenomena, thereby producing structures far from random. Further, certain vertices possess high centrality and can be regarded as significant and influential vertices that can become cluster centers that connect with high membership to many of the surrounding vertices. We propose a fuzzy clustering method to meaningfully characterize assortative, as well as disassortative, networks by adapting the Bonacichi’s power centrality to seek the high degree centrality vertices to become cluster centers. Moreover, we leverage our novel modularity function to determine the optimal number of clusters, as well as the optimal membership among clusters. However, due to the difficulty of finding real-world assortative network datasets that come with ground truths, we evaluated our method using synthetic data but possibly bearing resemblance to real-world network datasets as they were generated by the Lancichinetti–Fortunato–Radicchi benchmark. Our results show our non-hierarchical method outperforms a known hierarchical fuzzy clustering method, and also performs better than a well-known membership-based modularity function. Our method proved to perform beyond satisfactory for both assortative and disassortative networks.
Volar DRUJ Instability After Midshaft Both-Bone Forearm Fracture in a Toddler
Authors: Stocker-Downing T. Hunter , Biolzi Francesco , O'Brien Frederick P. , Shaw K. Aaron
Published: November 2021

Case:

A 2.5-year-old male child presented to the clinic for evaluation of left wrist popping. Ten months earlier, he sustained a closed left both-bone forearm fracture (BBFF) treated with reduction and casting. His clinical course was complicated by redisplacement requiring secondary manipulation and casting before osseous union. His parents reported wrist popping with active motion in the setting of a 20° apex volar malunion of the midshaft radius. He has been treated with observation and monitoring of deformity remodeling.

Conclusion:

Distal radioulnar joint instability is a potential complication of malunited BBFF, even in a pediatric population. Residual deformity, especially in the radius, should prompt clinical follow-ups after osseous union to assess functional recovery and deformity remodeling.

Thoracic spine height is cited as a crucial outcome measure in the treatment of early-onset scoliosis (EOS) because of its reported relationship to pulmonary function tests (PFTs). An 18-cm threshold has been proposed, although this single parameter might be overly simplistic for cases of different etiologies and deformity magnitude. We aimed to reevaluate pulmonary function in patients undergoing corrective surgery, assessing the role of residual scoliosis as well as spine elongation

Methods:

Patients undergoing EOS correction with a minimum of 5 years of follow-up since initial treatment were evaluated. Standard spirometry (forced vital capacity [FVC], forced expiratory volume in 1 second [FEV1]) was correlated to deformity magnitude and T1-T12 height. Patients were compared by age at first surgery (<5 or ≥5 years), final thoracic height (≤18 or >18 cm), and percentage of predicted pulmonary function (<60% or ≥60%).

Results:

Twenty-nine patients (15 congenital, 11 syndromic, and 3 idiopathic cases) were tested at a mean of 8.5 years following initial surgery. Twenty-two patients (mean initial age, 4.8 years) had growth-sparing instrumentation, and 7 patients (age, 5.1 years) had definitive fusion performed. Age at initial surgery was not associated with a difference in PFT results at the time of follow-up, and both age groups had ominously low percentages of predicted pulmonary-function volumes (50% to 55%). Only 18 of the 29 patients achieved a T1-T12 height of >18 cm. Those with a thoracic height of ≤18 cm had similar percentage-of-predicted spirometry results at the time of follow-up as those with greater thoracic height, possibly because of increased deformity correction. Only 14 of 29 patients had spirometry of ≥60% of predicted volume at the time of follow-up. These 14 had slightly smaller curves and slightly greater T1-T12 heights but significantly better spirometry results than the 15 subjects with <60% of predicted volume. For those with a T1-T12 height of ≤18 cm, the residual Cobb angle negatively correlated with spirometry results. In those with a final T1-T12 height of >18 cm, spirometry did correlate with thoracic height, especially when residual deformity was ≥60°.

Conclusions:

Regardless of thoracic height of ≤18 or >18 cm, with residual curves of >50o, pulmonary function was ominously low in fully half of the patients, raising doubt about the value of this threshold as an EOS outcome parameter.

Background and Objective: Helicobacter pylori infection of the stomach is a common disease and the resulting changes from it are numerous and deserve to be in the focus of researchers' attention. The aim of this study is to assess the expression of mutant P53 protein and Ki-67 markers in patients with gastritis secondary to Helicobacter pylori.Methods: Thirty samples with positive Helicobacter pylori gastritis were included in a retrospective study in Mosul / Iraq. The histological parameters were assessed using the Sydney system, then the expression of Ki67 and P53 expression were studied by immunohistochemical methods. The significance level was appointed at (0.05).Results: Ki67 and P53 expression were found in 83.3% of the total cases. The study results show that 92% of positive Ki67, P53 cases had chronic inflammatory cell infiltration, polymorph nuclear cells infiltration, and atrophy. Whereas 96% of positive Ki67 cases had no metaplasia, 92% of the positive P53 cases had no metaplasia. The results also showed that only 16% of the positive Ki67 cases had dysplastic changes, and 24 % of the positive cases of P53 cases were showed dysplasia. moreover, whenever P53 was negative; there is neither metaplasia nor dysplasia in the tissue, this does not apply to Ki67 negative cases.Conclusions: Ki67, P53 expressions increase with chronicity of Helicobacter pylori-positive gastritis, P53 expression is amplified when atrophy is present in these samples

Background

Cystic fibrosis (CF) is a common, life-threatening genetic disease in Caucasians but rarely reported in Chinese population. The prevalence and population-specific genetic spectrum of CF in China needs to be systematically estimated and compared with Caucasians.
Materials & Methods

We reviewed 30,951 exome-sequencing samples, including 20,909 children samples and 10,042 parent samples, from Chinese Children's Rare Disease Genetic Testing Clinical Collaboration System (CCGT). After the in-lab filtration process, 477 candidate variants of CFTR gene were left and 56 variants were manually curated as pathogenic/likely-pathogenic (P/LP). These P/LP variants were adopted to estimate CF prevalence in three methods: the carrier frequency method, the permutation-combinations method and the Bayesian framework method. Allele frequencies of the 477 CFTR variants were compared with non-Finland European (NFE) and East Asian (EAS) from gnomAD database. To investigate the haplotype structure difference of CFTR, another 2,067 whole-genome-sequencing samples from CCGT and 195 NFE from 1000 genome project were analyzed by Shapeit4 software.
Result

With the 56 manually curated P/LP variants in CFTR gene, the estimated Chinese CF prevalence is approximately 1/106,400. Only 21 (37.5%) of the 56 variants were included in Caucasian specific CF screening panels, resulting in significantly under-estimation of CF prevalence in our children cohort (1/114,659 vs. 1/1,121,017, P=9e-27) and parents’ cohort (1/96,968 vs. 1/797,207, P=1e-10). The allele frequencies of six pathogenic variants (G970D, D979A, M469V, G622D, L88X, c.1766+5G>T) were significantly higher in our cohorts compared with gnomAD-NFE population (all P-value<0.1). Haplotype analysis showed more haplotype diversity in Chinese compared to Caucasians. In addition, G970D and F508del were founder mutation of Chinese and Caucasians with two SNPs (rs213950-rs1042077) identified as related genotype in exon region.
Conclusions

Chinese population showed significantly different genetic spectrum pattern in CFTR gene compared with Caucasian population, and thus a Chinese-specific CF screening panel is needed.

BackgroundHemangiopericytoma was first named as a soft tissue tumor in 1942. It is a group of tumors composed of short spindle cells with pericyte growth. It is rare in clinical practice and accounts for 0.4 of all tumors originating in the central nervous system 0.4%, with a high degree of recurrence and the potential for metastasis outside the central nervous system.Case presentationWe report 4 patients, including 1 male and 3 females. All patients had headache, dizziness, and fatigue. The first and fourth patients showed acute exacerbation, paroxysmal limb twitching, flexion of both upper limbs, straightening of both lower limbs, unconsciousness, unresponsiveness, and upper eyeballs. Turning and closing of the teeth, 1 out of 2 patients was accompanied by a tongue bite. All 4 patients underwent imaging examinations. Considering the possibility of meningiomas and gliomas, all 4 patients underwent surgical resection and were followed up many times after the operation. The first case was followed up for 68 months and passed away due to recurrence without treatment. The second case was followed up for 50 months and relapsed at 42 months after the operation. It relapsed again 18 months after the operation and passed away with multiple metastases throughout the body; the third patient died in time The 4 patients were followed up for 32 months and 9 months respectively, and there is no recurrence at present.ConclusionsMeningeal HPC is a rare clinical tumor. 4 cases were followed up for 9-68 months, 2 cases recurred after surgery, and 1 case had multiple metastases throughout the body. It is not easy to distinguish HPC from meningioma on imaging. The diagnosis still depends on pathological examination, combined with the combined diagnosis of STAT6, CD34 and ALDHIA1 immunohistochemical markers, which can effectively improve the diagnosis and differential diagnosis of the disease. Because HPC is prone to recurrence and metastasis, Long-term follow-up and timely follow-up are still needed after operation.

Background

Impulsivity and substance use disorders (SUD) can be related to the same environmental factors. In this study, we intended to evaluate the dopaminergic function in imprisoned SUD offenders through the determination of s-COMT activity.
Methods

The study included 46 male individuals from a Portuguese penal institution. The participants were assessed through a battery of standardised instruments: Psychopathy Checklist-Revised (PCL-R), Barratt Impulsivity Scale Version 11 (BIS-11), and the European version of the Addiction Severity Index (EuropASI). s-COMT erythrocyte activity was evaluated.
Results

Overall, 73.9% (n=34) of the individuals had Antisocial Personality Disorder (ASPD) and 58.7% (n=27) presented SUDs. We evidenced, for the first time, that, in SUD individuals, s-COMT activity is correlated with the severity of drug dependence (EuropASI) (p<0.05), and with BIS-11 factors self-control (p<0.0001) and non-planning (p=0.002).
Conclusions

This study opens new perspectives regarding the pharmacological intervention on drug dependence through the interference on dopamine pathways.
Sitosterol-mediated Antioxidant Regulation to Enhance Heat Tolerance in Creeping Bentgrass
Authors: Rossi Stephanie , Huang Bingru
Published: November 2021

Heat stress symptoms in cool-season plants are characterized by loss of chlorophyll (Chl) and membrane stability, as well as oxidative damage. The objectives of this study were to determine whether foliar application of β-sitosterol, a naturally occurring plant metabolite, may promote heat tolerance by suppressing heat-induced leaf senescence as indicated by the maintenance of healthy turf quality (TQ), and Chl and membrane stability; and to determine its roles in regulating antioxidant metabolism in creeping bentgrass (Agrostis stolonifera). ‘Penncross’ plants were exposed to heat stress (35/30 °C day/night) optimal temperature conditions (nonstressed control, 22/17 °C day/night) for a duration of 28 days in environment-controlled growth chambers. Plants were foliar-treated with β-sitosterol (400 µM) or water only (untreated control) before heat stress, and at 7-day intervals through 28 days of heat stress. Plants treated with β-sitosterol had significantly greater TQ and Chl content, and significantly less electrolyte leakage (EL) than untreated controls at 21 and 28 days of heat stress. Application of β-sitosterol reduced malondialdehyde (MDA) content significantly at 21 and 28 days of heat stress, and promoted the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX) from 14 through 28 days of heat stress. β-Sitosterol effectively improved heat tolerance through suppression of leaf senescence in creeping bentgrass exposed to heat stress in association with the alleviation of membrane lipid peroxidation and activation of the enzymatic antioxidant system.

Introduction. Feldspar raw material is a natural source of silica, alumina, and alkali metal oxides. Each type of feldspar is distinguished by its applications and concentration methods. The main effective method of feldspar raw material concentration is flotation in the course of which the majority of harmful impurities are separated. However, this method is rather costly due to flotation reagents purchase, tailings ponds organization and maintenance, etc. Research relevance. Feldspar dry concertation technologies are promising in terms of resource-saving but uncommon. So, the development of a dry concertation technology for feldspar raw materials seems highly relevant. Research objective is to study the possibility of employing dry concentration technology to process feldspar raw materials at the new Kedrovoe deposit Methods of research. Laboratory equipment of JSC Uralmekhanobr was used for the research, namely centrifugal crusher DC-0.5; centrifugal deflection mill; laboratory-scale cascade classifier; dry electromagnetic separator SMS-20M ITOMAK, and tribo electrostatic separator.
