Authors: Hutor Liubov , Sodomora Pavlo
Published: May 2022

Celem przeprowadzonych badań było wdrożenie japońskich doświadczeń w szkoleniu komunikacyjnym za pomocą cyfrowych opowieści (digital storytelling, DST) we Lwowskim Narodowym Uniwersytecie Medycznym im. Danyła Halickiego w warunkach kwarantanny COVID-19 i uczenia się na odległość. W artykule omówiono skuteczność treningu i techniki ewaluacji opartej na DST w rozwoju umiejętności komunikacyjnych. W badaniu wzięło udział 76 studentów pierwszego (N = 38) i drugiego roku medycyny (N = 38). Ocena umiejętności DST dokonywana była według 10 kryteriów (8 strukturalnych, 2 stylistycznych) i przebiegała w trzech etapach: wstępnym, rozwojowym i końcowym. Uzyskane dane zostały przetworzone i przeanalizowane statystycznie. Wyniki badań analizowano za pomocą (I) różnic między grupami i (II) różnic między etapami. Wskazują one na istotną poprawę umiejętności DST w obu grupach eksperymentalnych na trzech etapach badawczych (p < 0,01). Szybka dynamika rozwoju umiejętności DST wiąże się przede wszystkim z lepszą poprawą umiejętności DST według kryteriów strukturalnych w porównaniu z kryteriami stylistycznymi u wszystkich uczestników (p < 0,01). Zjawisko to wskazuje na konieczność dalszej analizy i zwrócenia większej uwagi na rozwój umiejętności leksykalnych i gramatycznych studentów medycyny. Badani potwierdzili skuteczność metody DST w treningu komunikacyjnym i możliwość jej zastosowania w wyższej edukacji medycznej jako narzędzia rozwoju umiejętności komunikacyjnych.
Escritura científica en la Universidad : recomendaciones para los ingenieros de cómo citar y referenciar con el manual de estilo IEEE
Authors:   Universidad Libre, Arce Narváez Gloria Cristina
Published: May 2022

Esta serie da cuenta de la compilación y traducción de los manuales de citación APA de la Asociación Americana de Psicología (séptima edición de 2019); IEEE del Instituto de Ingenieros Eléctricos y Electrónicos, así como de la Norma Icontec NTC 1486. Este manual opera como instrumento de consulta para profesores, estudiantes y demás integrantes de la comunidad académica y científica en particular, convirtiéndose en un apoyo valioso para la presentación de trabajos académicos, artículos científicos, monografías, ensayos, tesis de maestrías y doctorados, entre otros. La era discursiva marcada por voces polifónicos que transitan en distintas enunciaciones y campos de conocimiento presenta hoy enormes dificultades bajo los parámetros de arbitraje exigidos por la comunidad científica nacional e internacional. En este sentido, es recurrente la frustración que sienten los autores de artículos científicos e investigadores después del rechazo de sus productos, y tras el veredicto por parte de pares académicos en los que se señalan problemas de citación, inadecuada presentación de referencias bibliográficas, márgenes sin las medidas correctas, tipos de letra diferentes, notas aclaratorias y demás dificultades que entorpecen el proceso de publicación y aceptación de sus trabajos. Adicional a esto, en el contexto global caracterizado por el desarrollo tecnológico y científico, la facilidad de acceso a la información posibilita la interacción con todo tipo de discursos donde se hace necesario reconocer la voz del otro y otorgarle su legitimidad mediante una correcta citación para que, dicho sea de paso, se evidencie en la escritura académica y científica el respeto y el reconocimiento a los derechos de autor. Teniendo en cuenta las anteriores consideraciones, este manual es de suma importancia puesto que sistematiza y compila de manera organizada tres tipos de normatividad ampliamente utilizadas por la comunidad científica y académica en el contexto nacional e internacional.

: To examine the clinical efficacy of laser peripheral iridotomy (LPI) in subjects with primary angle closure (PAC).

134 patients with angle closure glaucoma were included in this retrospective study which was carried out at the glaucoma clinic, department of ophthalmology at DR B.R Ambedkar medical college and hospital over a period of 2 years.

A total of 134 patients, 268 eyes were participated in this study. All were treated with LPI. The 268 eyes with Successful opening of angle more than 2 for at least 24 weeks. Follow-up ranged from 4 to 24 weeks. Gonioscopy was performed in each visit to confirm the angle status and patency of iridotomy. Success is defined as opening of more than 2 angles ITC for at least 24 weeks, with no need for further medication or laser treatment.

The percentage of open angle at 4 weeks was more 2 angles in 72 eyes(26.9%), ITC>3 angles in 56eyes, (20.9%) and ITC>4 angles in 140 eyes are (52.2%), at 12weeks more 2 angles 48 eyes (17.9%), ITC> 3angles in ,60 eyes (20.9%) ITC>4 angles in 160 eyes (59.7%) and 24 weeks was more 2 angles eyes 28 (10.4%), ITC> 3,60 eyes (22.4%) ITC>4 angle in180 (67.2%).

The success rate at 24 weeks ITC more than2 angle was 10.4%, ITC>3angles 22.4% and ITC> 4angles in 67.2% respectively.

In all cases, IOP was measured within 1 hour and IOP elevation of greater than 8 mm Hg was observed in eyes (15.7%). Mild-to-moderate anterior chamber reaction is seen in 128 eyes, hyphema in 12 eyes, ghost images seen in 4 eyes, 4cases of macular edema, cataract progression seen in 32 eyes, and iridotomy in 52 eyes were noted.

Post laser procedure combination of steroid and antibiotic medication was prescribed for 5 days and IOP pressure more 8 mmHg seen in 42 eyes(15.7%), antiglaucoma medications started and oral T. Diamox 250mg 2 tablets were prescribed followed up after 5 days to reassurance.

LPI is an effective treatment option for all patients with in Primary Angle Closure suspect to prevent the acute angle closure glaucoma. LPI is a effective, compliance free, repeatable, most PACS eyes don’t receive further treatment and safe therapeutic modality having only minor, transient, self-limiting or easily controlled side effects with no sequelae. Progression to PACG is uncommon in PACS and PAC. Despite our methodology, the inherent limitations of studies should be considered, and conclusion drawn from our pooled results should be interpreted with caution. Future large-volume, well-designed with extensive follow-up are awaited to confirm and update the findings of this analysis.

Published: May 2022

Wooden foreign bodies (WFBs) in and around the orbit are known to go undetected partially or in toto by conventional modalities like computed tomography (CT) and magnetic resonance imaging (MRI) and have serious long term complications such as infection, abscess or fistula formation, orbital cellulitis and intracranial migration. A keen inspection of the wound site before, during and after primary removal are crucial in preventing development of vision-threatening and potentially fatal complications due to retained vegetative elements. With a case report, we aim to highlight the importance of radiological investigation and a high degree of suspicion in cases of injuries with WFBs.
VMD Based Image Quality Enhancement Using Multi Technology Fusion
Authors: Satapathy Lalit Mohan , Das Pranati
Published: May 2022

Despite the success of various enhancement techniques used in many bio-medical applications, edge-preservation-based image enhancement remains a limiting factor for image quality and thus the usefulness of these techniques. In this paper, a new enhancement technique combining the variational mode decomposition (VMD) with the Sobel gradient and equalization technique is proposed. The proposed algorithm first decomposes the image into various sub-modes based on their frequency. The low-frequency components are equalized using the conventional equalization technique, whereas the high-frequency components use a traditional filter. Finally, the edge of the original image is added to the processed image for quality assurance. The proposed algorithm has two advantages over the existing approaches by enhancing only the low-frequency components to extract the hidden artefacts and specifically de-noising the high-frequency component. This process not only enhances the contrast, but also preserves the brightness of the image. A comprehensive study was conducted on the experimental results of benchmark test images using different performance measure matrices to quantify the effectiveness of the approach. In terms of both subjective and objective evaluation, the reconstructed image is found to be more accurate and visually pleasing. It also outperforms the state-of-the-art image-fusion methods, especially in terms of PSNR, RMSE, mutual information, and structural similarity.

Published: May 2022

People are known to change their behavior and decisions to conform to others i.e., to be accepted by peers. Peers play a significant role in adolescent growth. This study shows the findings of the research of which the point was to gain insight into students’ – future school and preschool teachers’ – self-assessment of their own relationships with peers i.e. to determine the areas and differences in susceptibility to peer pressure and in relationships with peers. The research was conducted on students of the Faculty of Educational Sciences Pula, Croatia and the Faculty of Education in Jagodina, Serbia (N=411).
The results we obtained show that the area of greatest susceptibility to peer pressure on the observed sample of students supports the interpersonal theory. Variability in self-assessment of certain areas of responsiveness to peer pressure and relationships with peers according to place of study of the observed groups of students at the latent and the manifested level were also found. It can be concluded that the observed cities have different degrees of social and also psychological relations.
The value of these results is that they enable insight into students’ various areas of susceptibility to peer pressure and differences with respect to different environments or places of study, which opens space for improvements.

Published: May 2022

Over the past 20 years, the strategic goal for Ukraine is to implement European standards into the practice of managerial activity, which should ensure sustainable socio-economic development of the state and improve the level and quality of life. The activities of state structures show that only the active creation of regulations, the content of which provides for the implementation of a number of reforms, does not lead to the expected results, because as a critical analysis of their content proves, such documents do not contain clear guidelines for implementation of reforms. This leads to negative consequences, which are manifested in the rapid deterioration of the quality of life, reduces the quality of educational, medical, administrative and other services.
One of the most important spheres that ensure sustainable socio-economic development of any country is education. We tried to answer a number of questions: is the implementation of educational reforms in Ukraine successful in the context of the government’s European integration policy; what are the advantages and disadvantages of implementing European standards into the practice of functioning of the educational sphere of Ukraine; which, in the opinion of the participants of the educational process, should be priority ways to improve the quality of education of the provision of educational services.
Thanks to the conducted sociological research, we assessed the existing challenges and threats that slow down the implementation of relevant reforms and outlined promising ways to ensure quality and effective reforming of the educational sphere of Ukraine.

A scientific understanding of building a rational system of long-term training for footballers in Ukraine, as well as ways of its practical implementation, should rely on foreign experience in this field to be effective. The article aims to theoretically and methodologically justify foreign experience in building a rational system of long-term training for footballers. Each country demonstrates its options for solving this particular problem. The countries occupying leading positions in European football have well-established organizational and management systems for training and selection of athletes in the process of long-term improvement. In general, all of the above-mentioned countries use similar systems with their own specifics stemming from national traditions, economic and logistical conditions. Differences in the training of footballers from different countries are due to the different role and degree of participation of governmental, non-governmental and private structures.

Published: May 2022

Background: The most common problem in forensic personal identification, particularly in paternity tests, is the availability of information originating from a mother or a father that can be used as a comparison in the forensic DNA examination process. The use of sibling analysis in paternity tests is still not widely known. Materials and methods: The respondents of this study were 25 families of the Madurese population with 6, 9, and 10 sibling pairs categorized as female-female, male-male, and male-female siblings. The kinship relationship was analyzed by using 13 STR CODIS loci technique (TPOX, D3S1358, FGA, D5S818, CSFIPO, D7S820, D8S1179, THOI, vWA, D13S317, D16S539, D18S51, D21S11), and Amelogenin (Amel) x: 106bp,y: 112bp). Results: The results of DNA contents and purity examination of the extracted DNA sample showed that the average value of DNA contents was 675±5.35 ng/μL with a purity range of 1.05-1.86. The findings proved that the male-male siblings of the Madurese population had the highest allele sharing percentage at the loci of D13S317, D16S539, and D21S11. The highest allele sharing percentage for female-female siblings was at the loci of TPOX and D21S11. Meanwhile, the male-female siblings had the highest allele sharing percentage at the loci of TPOX, D5S818, vWA, D7S820, THO1, vWA, and D13S317. Conclusion: The main STR loci recommended in the male-female siblings of Madurese population identification are TPOX, D13S317, and D21S11.

Published: May 2022

Environmental pollution by microplastics (MPs) has become a global problem, but little is known about MPs in soils. This is because MP extraction methods from soils have not yet been standardized. In this study, we tried to establish a simple and economical method to extract soil MPs using the buoyancy of canola oil and the density separation process using sodium chloride (NaCl). First, the ability and suitability of seven different oils to extract MP from soil were investigated and canola oil was selected. Then, the spiking and recovery test was performed with canola oil and NaCl solution for low-density polyethylene (LDPE), polypropylene (PP), and polyvinylchloride (PVC) as follows: 1) soil and MP mixtures were prepared, 2) 5 g L-1 NaCl and canola oil were added and shaken thoroughly, 3) the oil phase containing MPs were separated after sedimentation, 4) the extracted MPs were rinsed with 99.5% ethanol, and 5) the organic adherents to the extracted MPs were digested with hydrogen peroxide. After drying and incineration, the substantial recovery rates were calculated. In the spiking and recovery test for MP particles (<1 mm) from five typical Japanese agricultural soils, the recoveries of LDPE, PP, and PVC were 95.2-98.3%, 95.2.7-98.7%, and 76.0-80.5%, respectively, higher than those obtained by the density separation using saturated NaCl solution. In conclusion, the method is effective for extracting MPs, especially LDPE and PP, from soils and is less sensitive to soil type, texture, and physicochemical properties.

Published: May 2022

Background:Human papillomavirus is one of the most important sexually transmitted viruses that causes cervical cancer. In women undergoing cervical screening, it is important to be aware of ways to minimize anxiety.The present systematic review was conducted to determine the reproductive health needs of women with HPV.Methods:In this systematic review, articles without time constraints were searched in PubMed,Scopus,Web of Science, Google Scholar and Iranian Magiran,SID and Iranmedex. Keywords used: HPV, Information, Want, Need, Know, etc. and their Persian equivalents in the title and abstract of the articles.Papers after identification independently by two researchers Contradictions were evaluated and discussed with the third author.Results: At first 1056articles were retrieved which after removing,13articles published between2004-2021were entered.The studies were mostly qualitative(N=9),quantitative(N=3), and one was unclear.Most qualitative studies collected data using individual interviews(N=7), two qualitative studies,narratives of HPV patients from a website of patient experiences and questions. The quality evaluation showed that good=8, Average=2, and one was of poor.Conclusion:Surveys showed that the majority of women had unanswered questions about their HPV test results. The information that women thought was helpful in interpreting their test results included having a high-risk type of HPV, the risk of short-term and long-term cancer, and cancer survival statistics for the virus. Women also needed information about sexual transmission, how HPV tested positive in a long-term relationship, and the potential consequences for their partners and the risk of re-infection. Younger women had questions about whether HPV could affect fertility.
Plant Functional Type Specific Response to Nitrogen Addition under Different Rainfall Regimes
Authors: Mishra Swati , Singh Hema
Published: May 2022

Grassland productivity is one of the critical characteristics which is co-constrained by nitrogen and water availability. Therefore, an understanding of how grasslands species respond to atmospheric nitrogen (N) deposition and rainfall variability needs to be systematically and quantitatively evaluated on temporal scales. In this study, we performed an experiment to evaluate the responses of aboveground and belowground biomass of grassland community and aboveground biomass of grasses, forbs and legumes at a tropical location for two years (2017–2019) using rainout shelters to simulate three rainfall conditions with three N levels. The study indicates that a higher water and nitrogen input significantly increases the aboveground and belowground biomass of the tropical grassland community in the first year but in the second year in N2 (20g N m− 2/yr− 1) plots under all the rainfall conditions, both above and belowground biomass decreased. Interestingly, rainfall had a significant effect on grasses and forbs but not on legumes while nitrogen treatment had a significant effect on all three plant functional groups. On a temporal scale, we found the significant effect of years on belowground biomass of grassland community, grasses and forbs only. Only grasses exhibited the significant interactive effect of rainfall and nitrogen. Observed plant functional type-dependent plant response to changes in rainfall regime and N input indicates that future changes in productivity of tropical grassland due to anthropogenic changes will be strongly dependent on the direction of changes in species composition.

Published: May 2022

The wireless communication channel is the critical parameter that affects the throughput in the LTEA network. The user equipment measures the quality of the wireless channel as the channel quality indicator (CQI) value and transmits it to eNodeB. The eNodeB uses the CQI value to select the adaptive modulation and coding method to achieve the highest throughput. This study analyzes the LTE-A network based on actual field measurements. Measurements were taken at 80 different locations in Samsun (Turkey) city center using TEMS Investigation software. RSRP, RSRQ, SINR, CQI, and throughput values were recorded for each measurement in a stationary position while downloading 500 MB of data. Then, the averages of these recorded data were calculated, and detailed analyses were performed. At the end of the study, the effects of RSRP, RSRQ, SINR, and CQI on the throughput value in the LTE-A network were examined, and a novel mathematical model was proposed that gives the relationship between them with 88.85% accuracy. It has also been observed that the accuracy of the proposed model can be increased by 4% with GRNN. In the last stage of the study, a new CQI mapping method based on real-field measurements for the LTE-A system was developed.
Design and Development of Underwater ROV for Dam Inspection
Authors: Elangovan Muniyandy , Yuvan Siddarth B , Uduupa Govindram R , Babu Mohan M
Published: May 2022

India is a developing country that relies heavily on agriculture. A large number of dams have been built to store water and use it when it is required for agriculture. Physical inspection is currently performed outside of the dam, but it is not done efficiently inside the dam due to a lack of technology to reach the bottom of the dam and the wall inside the water. Keeping those criteria in mind, this project has created a vehicle (robot) that can dive into the dam water and take video and possibly photographs to verify the consistency of the wall's condition. This system includes a camera for capturing damage and estimating the need for wall reinforcement. It helps to identify the weaker or damaged part of the dam wall. Outside the Dam, a monitoring system is installed to collect data from the ROV and determine if additional action is required for additional inspections. Since there isn't enough light in the deeper parts of the dam, lighting is needed. It is recommended to have a small pump to get the water so that the consistency of the water can be checked at any time. This vehicle can assist the community in maintaining high-quality water in a dam for human consumption while reducing the risk of human injury during an inspection.

Published: May 2022

Background: The asymmetry of paravertebral muscle (PVM) degeneration in degenerative lumbar scoliosis (DLS) patients has been extensively studied by imaging and histological examination and has not yet been verified by surface electromyography (sEMG) techniques.Objective:To study the relationship between the surface electromyography (sEMG) and degenerative characteristics of paravertebral muscles (PVMs) in patients with degenerative lumbar scoliosis (DLS).Method:In twenty DLS patients and fifteen healthy subjects, sEMG activity of the PVMs at the level of the upper end vertebra (UEV), apical vertebra (AV) and lower end vertebra (LEV) was measured during static standing and dynamic standing forward flexion and backward extension tasks. Action segmentation was achieved according to inertial measurement unit (IMU) data.The sEMG characteristics of the PVMs on the convex and concave sides were compared, and the relationship of these data with the Cobb angle and lumbar lordotic angle (LL) was analyzed.Results:In the DLS group, there was no difference in sEMG activity between the convex and concave sides at the UEV or AV level， but in the motion and return phases of the standing forward flexion task (P=0.000, P=0.015) and the maintenance and return phases of the standing backward extension task (P=0.001, P=0.01), there was a significant difference in sEMG activity between the convex and concave sides at the LEV level.Asymmetrical sEMG activity at the LEV level was negatively correlated with the Cobb angle (F=93.791，P <0.001) and LL angle (F=65.564，P <0.001).Conclusion:In the DLS group, asymmetrical sEMG activity of the PVMs appeared at the LEV level, with the concave side being more active than the convex side. This sEMG characteristics were consistent with their imaging and histological degenerative features and correlated with bone structural parameters.

Objectives To evaluate the specific imaging features of ovarian sclerosing stromal tumor (SST), improve its accuracy and specificity of imaging diagnosing, and prevent overestimation of malignancy and reduce unnecessary surgical procedures.Methods Eight patients with magnetic resonance imaging (MRI) and six with computed tomography (CT) images were analyzed in this retrospectively observational study. All cases were confirmed by postoperative pathological examination as ovarian SST. Imaging and pathological features were analyzed.Results All the 14 masses were showed cystic and solid components with outer surface of tumors contained a capsular and complete smooth rim. Eight tumors of MRI showed “lake-island” sign on T2 weighted imaging (T2WI). Two of the 6 CT cases found a flaky calcification. One case showed as a multiloculated cystic mass with irregularly thickened septae and tumor wall. The solid components in other 13 masses are comb- or wheel-like enhanced. After injection of contrast agent, the solid components in 8 cases (57.1%) appeared as early enhancement, while the other 6 cases (42.9%) appeared as progressive enhanced, and the cystic components of all cases had no enhancement in the whole course. Vascular flow signals or/and marked enhancement of blood vessels were found in 12 lesions (85.7%). Pathologic examination demonstrated pseudolobule patterns, round to spindle cells, collagenous areas, edematous hypocellular areas and prominent vasculatures.Conclusions The results demonstrated that MRI with “lake-island” signs on T2WI and MRI/CT dynamic enhencement could play a critical role in making appropriate diagnosis preoperatively.

Published: May 2022

BackgroundhTERT promotor mutation represents a common and early event in hepatocarcinogenesis. Its linkage with the morphologic status of the underlying liver tissue is not really understood. We analysed the connection between the histopathological changes of tumour bearing liver tissue and the occurrence of hTERT promotor mutation in hepatocellular carcinoma, correlated with clinical data. MethodsThe study cohort comprised 160 histologically confirmed hepatocellular carcinomas (HCC) in liver cirrhosis and non-cirrhosis which were investigated for hTERT promotor mutation. Frequency of hTERT promotor mutation in HCC in cirrhosis and non-cirrhosis was evaluated and correlated with potential clinical and histopathological drivers. Especially, tumour bearing non-cirrhotic liver tissue was examined regarding inflammation, modified histological activity index (mHAI), fibrosis and steatosis and its correlation with the frequency of hTERT promotor mutation in HCC. Overall survival analysis via multivariate Cox regression analysis was performed. Furthermore, hTERT antibody immunohistochemistry and molecular hTERT promotor mutation analysis of both HCC and background liver tissue were compared.ResultshTERT promotor mutation was especially related to HCC in cirrhosis compared to non-cirrhotic liver tissue (p < 0.001) and independently from cirrhosis to HCC in patients ≥ 60 (p = 0.005). Furthermore, hTERT promotor mutation was associated with liver cirrhosis caused by alcohol toxicity and hepatitis C virus infection (HCV). In non-cirrhotic liver tissue the frequency of hTERT promotor mutated HCC increased with the degree of inflammation and fibrosis. Nevertheless, 25% of hTERT promotor mutated HCC developed in normal liver tissue without HCC risk factors. Multivariate Cox regression analysis did not show an influence of hTERT promotor mutation in HCC on overall survival of 3, 5 and 16 years. Immunohistochemical analysis with the hTERT antibodies LS-B95 and 2D8 hTERT promotor mutated HCC and wildtype HCC showed a mildly stronger immunoreaction compared to the tumour bearing liver tissue (LS-B95: p < 0.01, 2D8: p < 0.01).Conclusions Our study reveals a connection between pathological changes of tumour bearing liver tissue and hTERT promotor mutation in most HCC, even in non-cirrhotic liver tissue. Immunohistochemical hTERT antibodies do not discriminate between hTERT promotor mutated and wildtype HCC.

Phytase as a feed additive has been shown to promote broiler performance and bone mineralization. This study evaluated the effects of microbial phytase (produced by L. plantarum A1-E and C. tropicalis TKd-3) on growth performance, metabolic energy, ileal histomorphology, and meat and bone mineralization in broilers. One hundred forty one-day-old broiler chicks were distributed into four treatments, five replicates, and seven chicks in each replicate. The experiment consisted of (FA) basal diet without phytase (negative control); (FB) basal diet with L. plantarum A1-E phytase (500 FTU/kg of feed); (FC) basal diet with C. tropicalis TKd-3 phytase (500 FTU/kg of feed); and (FD) basal diet with commercial phytase (500 FTU/kg of feed, positive control). Results revealed that FB and FC treatments improved the broiler performance index (P < 0.05), and FC treatment tended to increase metabolic energy (P > 0.05). Ileal histomorphology showed that FB treatment increased villus height, villi height to crypt depth ratio, and villus surface area (P < 0.05). Breast meat mineral content of broiler revealed the highest mineral content in FB treatment, mainly of the minerals P, Mg, and Fe (P < 0.05). Moreover, the FC treatment resulted in the highest mineral content in thigh meat, particularly for the minerals Ca, P, Mg, Zn, and Fe (P < 0.05). Tibia bone mineralization showed that FB treatment had the most significant effect (P < 0.05) on the mineral content of P, Mg, and Fe. Conclusively, microbial phytase (L. plantarum A1-E and C. tropicalis TKd-3) increased performance index, whereas L. plantarum A1-E phytase improved villus surface area, increasing the ileum mineral absorption, breast meat mineral content, and tibia mineral deposits.

BackgroundPatients with Gout frequently use Complementary and Alternative Medicines (CAM therapies), which include Ayurveda medications and treatment procedures, and hence it is essential to determine their safety and efficacy/effectiveness.ObjectivesA systematic review of the published clinical data in view of the safety and efficacy/effectiveness of Ayurvedic treatment protocols in Gout viz-a-viz Vatarakta.MethodsWe searched the PubMed, Cochrane Library (Cochrane Central Register of Controlled Trials: Issue 6 of 12, June 2018), Google Scholar, AYUSH Research Portal (Govt. of India), DHARA, Ancient Science of Life, Shodhganga@INFLIBNET, Online clinical trial registers, and grey literature available from Government Ayurveda College, Trivandrum (Manual search) IPGT & RA, Gujrat Ayurveda University. We excluded abstract-only publications. We could not do a meta-analysis due to the unavailability of relevant studies. Study eligibility criteria: Cases diagnosed as Gout by laboratory findings and/or clinical symptoms, who underwent Ayurvedic treatment/Cases clinically diagnosed as Vatarakta, who underwent Ayurvedic treatment. Participants and interventions and controls: We included participants of either sex satisfying the inclusion criteria who underwent Ayurvedic treatment either Randomized controlled trials (RCTs), Quasi-Experimental Trials, Single group clinical trials, Comparative Clinical Trials (CCTs), and Pragmatic trials.ResultsA total of 398 potentially relevant studies were found, and 21studies met the inclusion criteria, among which ten studies were pre-post studies, seven studies were included among Randomized Comparative Clinical Trials, and four were among Comparative clinical trials.Conclusions and implications of key findingsEven though Ayurveda physicians are pragmatically treating/rehabilitating Vatarakta/Gout cases and reported satisfactory results in terms of both safety and efficacy/effectiveness, this review is unable to produce strong valid evidence to prove the efficacy/effectiveness and safety of Ayurveda over Non-Ayurveda interventions or Placebo due to lack of quality and unavailability of published works. So the authors propose well-organized and methodologically sound quality research works in this regard.Systematic review registration number- PROSPERO (CRD42019131198)
Diurnal, monthly, and seasonal variations of indoor radon concentrations concerning meteorological parameters

Published: May 2022

Indoor radon concentrations and meteorological parameters were measured in an office of the teaching staff at the Institute of Nuclear Sciences, Ege University. Data were collected hourly over 25 months (762 days). Raw data, diurnal, monthly, and seasonal variation of parameters were investigated separately. The results show that the average indoor radon concentration (18 Bq m− 3) is relatively lower than national and international reference values. Indoor radon concentrations showed an increasing and decreasing trend throughout the day. Radon concentrations are slightly higher in the morning (downtime and early hours of the day) and then reduced in the afternoon. This can be related to the daily routine usage of the office, which is affected by ventilation of the room, air temperature variations, etc.

Background Hypocalcemia is a common complication after total parathyroidectomy(t-ptx) in patients with secondary hyperparathyroidism(SHPT), which endangers the lives of patients, but the amount of intravenous calcium supplementation is very different in each patient.Therefore,We aimed to elop a predictive model of intravenous calcium supplementation needs in patients with SHPT after t-ptx.Methods Data for 550 SHPT patients treated in the Department of Hepatobiliary Surgery of the Northern Theater General Hospital were collected from January 2015 - December 2021, with patient biochemical indices being retrospectively evaluated.Results Sex (t=-1.988, p=0.049), serum ferriti (SF) (t=2.155, p=0.033), alkaline phosphatase (AKP) (t=4.501, p=0.000), free thyroxine (FT4) (t=-3.128, p=0.002) were identified as risk factors associated with the need for postoperative intravenous calcium supplementation. The developed predictve model (intravenous calcium supplementation =1235.561-158.547*gender + 0.141*SF + 0.442*AKP - 494.055*FT4; male: 0, female: 1) was effective and passed the F test (F = 22.034, P = 0.000).Conclusions The developed model can be used to reliably predict the amount of intravenous calcium supplementation required by SHPT patients following t-ptx, providing a clinical basis for an evidence-based calcium supplementation scheme.

The spread of COVID-19 misinformation on social media has become a major challenge for citizens, with negative real-life consequences. Prior research has focused on detection and/or analysis of COVID-19 misinformation. However, finer-grained classification of misinformation claims has been largely overlooked. The novel contribution of this paper is in introducing a fine-grained annotated misinformation dataset which distinguishes between statements that assert, comment or question on false COVID-19 claims. This new dataset not only enables social behaviour analysis but also enables us to address both an evidence-based and non-evidence-based misinformation classification. Lastly, through a ‘leave claim out’ validation, we demonstrate that classifier performance on unseen COVID-19 misinformation claims is significantly different, as compared to performance on topics present in the training data.
Redox evolution during arc magma differentiation revealed by mineral/melt Fe3+ and Fe2+ partitioning
Authors: Huang Fangfang , Wang Jintuan , Xiong Xiaolin
Published: May 2022

The oxidizing capacity of volcanic gases relies on both the redox state of the mantle and the redox evolution of mantle-derived magmas. Arc magmas transfer abundant volatiles from the mantle and undergo extensive differentiation before degassing. But how the magmatic redox state evolves during differentiation remains enigmatic. The redox evolution of a magma depends on the mineral/melt partition coefficients of Fe3+ and Fe2+ (DFe3+ and DFe2+). However, no systematic DFe3+ and DFe2+ are reported due to the difficulties in analyzing Fe3+ of silicate minerals. Here, we conducted hydrous experiments at 900−1100 °C and 1−2 GPa and determined systematically DFe3+ and DFe2+ using a novel method. With the obtained partition coefficients, we investigated the redox evolution by performing fractional crystallization modelling. The almost invariable redox state during arc magma differentiation implies an oxidizing mantle predated the Great Oxidation Event if it was triggered by the increasing oxidizing capacity of volcanic gases.
Hepatic urea, creatinine and uric acid metabolism in dairy cows with divergent milk urea concentrations

Published: May 2022

Milk urea concentration is an indicator for dietary nitrogen (N)-supply and urinary N-excretion. Dairy cows with high (HMU) compared to low milk urea (LMU) concentration have greater plasma urea, creatinine and uric acid concentrations, but if the liver metabolism accounts for these differences is unknown. Eighteen HMU and 18 LMU cows were fed a diet with a low (LP) or normal (NP) crude protein concentration. An N balance study was performed and a 13C-urea bolus was administered to measure urea pool size. Liver samples were analyzed by 2D-gel-based proteomics and RT-qPCR. Although HMU cows had a greater urea pool, plasma urea, uric acid, and hippuric acid concentrations, these differences were not associated with altered expressions of genes related to urea cycling or N-metabolism. Instead, HMU cows had higher oxidative stress levels. Conclusively, other factors than hepatic urea metabolism account for milk urea concentrations. Despite higher plasma urea concentrations and argininosuccinate synthase 1 protein expression on the LP diet, urea cycle mRNA expressions were not affected, indicating that its activity is not controlled at transcriptional level. Feeding the LP diet resulted in increased expressions of enzymes catabolizing fatty acids, which is presumably due to diminished microbial growth and insufficient energy supply.
