Twenty-one guitar students from an institution in Curitiba (Brazil) participated in the research. The re-search participants were 12 male and seven female students, most from 9 to 14 years old. In this section, we present the results and discussions of the questions about students' motiva-tion to learn guitar, their opinions about the group classes, and the class repertoire.
A execução e a composição melódicas como estratégias para facilitar o ditado melódico: dois experimentos
Authors: Lima Fernando , Caregnato Caroline
Published: February 2024

Melodic dictations are usually practiced in Ear Training classes and, associated with them, some strategies are employed by students and instructors in order to favor these types of ac-tivities. This study investigates two strategies that can be used in this context: composition and performance. The aims of this work are to investigate the influence of composition and musical performance, accomplished prior to a set of dictations, on the results of the latter; and to discuss the use of these strategies in Ear Training teaching. Two quasi-experimental studies were carried out, during the Covid-19 pandemic, involving a pre and a post-test applied on-line and formed by melodic dictations. Between them, the participants of the first experiment (N = 25) performed a compositional activity and, in the second (N = 44), they performed mu-sic. The results of these studies showed that composition and musical performance did not play a significant role on performance in melodic dictation. Explanations for this can be found in limitations of the online research instruments employed. However, we believe that the strategies investigated here can be used not as simple “formulas for success”, but as ped-agogical tools to be used in the long term for the development of perception. It is possible that future studies, carried out under better conditions, could observe the positive effects of mu-sical composition and performance.

Published: February 2024

The aging process is dynamic and progressive, leading to a decline in the domains of commu-nication and socialization. This essay aims to present the benefits of musicalization practices for older adults, focusing on cognitive and psychosocial aspects. Using music as an interven-tion tool may benefit several aspects frequently impaired during aging, including communi-cation structures, such as speech and audition, and stimulating cognition and neural plastic-ity through new learning experiences. Furthermore, singing in a choir stimulates environments for developing social support. Therefore, the choir may be recommended as a strategy to promote quality of life improvement for older adults.

Authors: Soares Leandro Taveira
Published: February 2024

This article presents a literature review about the Self-regulated Learning Microanalysis, one of the methodological approaches developed in the last decades to measure and evaluate the learning process in different contexts. I present a historical overview of the development of measure/assessment processes and tools for Self-Regulated Learning (SRL), the microanaly-sis approach in Social Cognitive Theory (Bandura, 1977a), and self-regulated learning (Cleary & Zimmerman, 2001; Kitsantas & Zimmerman, 2002), besides the recent proposals for the ap-plication of this evaluative/interventional technique in the musical field. This review seeks to support the arguments in favor of the viability of adopting microanalysis as a solid methodological approach and an effective didactic and academic tool for the development of performance pedagogy.

Micro, small and medium enterprises (MSMEs) had an important role in the Indonesian economy, with the creation of domestic products and the ability to absorb labor. In order to maintain the performance of MSMEs to exist and grow up, it was necessary to have a strategy carried out both from internal MSMEs themselves or the stakeholders. The aims of this study was to find out the strategy for developing the MSMEs cluster by using the analytic hierarchy process method. The determination of the sample used was by purposive sampling, namely members of the MSMEs home industry partner of LPB Pabanet, who were active and willing to be respondents with a total of 27 MSMEs. This study used a direct interview to respondents containing questions for clustering MSMEs, then a focus group discussion (FGD) was carried out with experts which aims to explore information used in formulating development strategies of MSME based on clusters. The results showed that based on the analysis using the fuzzy C-means method formed 3 clusters of SMEs. The strategy for the first cluster was on the production process criteria (0,391) with an alternative strategy for obtaining permits of P-IRT (0,351). In second cluster, the criteria with the highest weight was capital (0,395) with alternative strategies for making financial reports regularly (0,863). In the third cluster, the alternative strategy chosen on the marketing criteria (0,547) was to establish a partnership (0,407).

Published: February 2024

Optical microcavities are compact structures that confine resonant photons in microscale dimensions for long periods of time, greatly enhancing light–matter interactions. Plentiful and profound physical mechanisms within these microcavities or functional microcavities have been extensively explored, including mode shift/splitting/broadening, lasing and gain enhancements, surface plasmon resonance, fluorescence resonance energy transferring, optical frequency comb spectroscopy, optomechanical interaction, and exceptional point. The versatility in design and the diverse range of materials, particularly composites involving metals and 2-dimensional materials, have paved a way for innovative approaches and improved performance in biochemical sensing applications. Leveraging the advantages ranging from miniaturization, high sensitivity, rapid response, and inherent stability, optical microcavity-based biochemical sensors have emerged to address the growing and increasingly complex demands of biochemical detection. This review commences with an exploration of fundamental mechanisms and structures and then delves into typical applications in recent advancements, covering the detection of biomacromolecules, cells, solid particles, liquid ions, and gas molecules. This review also culminates with a forward-looking perspective, highlighting future development trends and crucial research directions.

Authors: Wang Haoqiang , Wang Yong , Yan Sheng , Du Xin , Gao Yuan , Liu Hong
Published: February 2024

We introduce an innovative approach to address a significant challenge in interaction recognition, specifically the capture of correlation features between different interaction body parts. These features are often overlooked by traditional graph convolution networks commonly used in interaction recognition tasks. Our solution, the Merge-and-Split Graph Convolutional Network, takes a unique perspective, treating interaction recognition as a global problem. It leverages a Merge-and-Split Graph structure to effectively capture dependencies between interaction body parts. To extract the essential interaction features, we introduce the Merge-and-Split Graph Convolution module, which seamlessly combines the Merge-and-Split Graph with Graph Convolutional Networks. This fusion enables the extraction of rich semantic information between adjacent joint points. In addition, we introduce a Short-term Dependence module designed to extract joint and motion characteristics specific to each type of interaction. Furthermore, to extract correlation features between different hierarchical sets, we present the Hierarchical Guided Attention Module. This module plays a crucial role in highlighting the relevant hierarchical sets that contain essential interaction information. The effectiveness of our proposed model is demonstrated by achieving state-of-the-art performance on 2 widely recognized datasets, namely, the NTU60 and NTU120 interaction datasets. Our model’s efficacy is rigorously validated through extensive experiments, and we have made the code available for the research community at

Authors: Martynov Vladislav , Lisyatnikov Mikhail , Lukina Anastasiya , Roshchina Svetlana
Published: February 2024

Caring for natural resources is one of the most important components of the sustainable development of the
national economy of the Russian Federation. This is facilitated by the use of low-grade wood, including fire-damaged
wood, as a structural material, which will reduce the cost of producing laminated wood structures (GWB) through the use
of cheaper raw materials. Based on a systematic analysis of sources and our own empirical research, the features of a new
technology for manufacturing laminated wood beams with a span of 6.0 m using wood damaged by fire from a forest fire
are presented. This study is aimed at reducing the material intensity of laminated timber structures through the partial use
of low-grade wood without reducing the load-bearing capacity of the beams. It was found that when replacing 36% of the
middle lamellas in the cross-section with thermally damaged wood, the reduction in the load-bearing capacity of the beam
structure relative to a beam made entirely of grade I wood was 9.7%, and when replacing 62% of the wood – 16.06%.
The use of thermally damaged wood in the manufacture of laminated wood structures will significantly reduce the use of
high-grade lumber with some changes in the technological process that do not lead to an increase in its cost. Using the
positive experience of testing beam FDCs, it is planned to further study the use of thermally damaged wood in compression-bending structures.
Daily and season transpiration intensive of Calluna vulgaris (L.) Hill in the trans-Ural south area
Authors: Kochubey Alena , Cherepanova Olga , Petrova Irina
Published: February 2024

The Trans-Ural region is the southern point of the common heather (C. vulgaris) range. Field ecophysiological
study of C. vulgaris plants transpiration intensity (IT) was carried out in connection with the problem of marginal populations adaptation to arid climate. The research was carried out in the forest-steppe of the Trans-Ural region (Kurgan
region), where an abundant population of heather grows. The dailyvariation of IT was studied taking into account a set
of recorded ecoclimate limiting factors (wind speed, illumination, dynamics of air temperature and humidity, soil temperature) during one growing season (from April to September 2016) under the canopy of a pine forest and in the adjacent
clearing. To study IT, annual apical shoots of plants 4 cm long were used in triplicate for each time period. The total
sample size on one day of measurements ranged from 30-35 shoots. The transpiration rate was determined by the rapid
weighing method, which takes into account the water lost by the shoot over a certain time period. When processing the
data, we used correlation analysis (Pearson's correlation coefficient r), which made it possible to clarify the strength and
direction of two continuous (metric) variables interaction. Differences in IT daily changes were revealed in plants growing
under the forest canopy and in the open areas. Under conditions of long-term atmospheric and soil drought, which is
common for the region, in 2016 a sharp decrease in heather water content was observed, starting from 10 a.m. throughout
the entire growing season, with the exception of April, when the moisture deficit in the soil and heather tissues was still
minimal. In May, maximum IT values in the clearing were noted at 14:00 (8.5 mg/h×10 –4) whereas under the canopy of
the tree stand, peak IT values begin at 10 a.m. (12.7 mg/h×10 –4). Daytime summer transpiration in common heather (C.
vulgaris) is even less intense than spring transpiration ((3–5 mg/h×10–4).It was revealed that meteorological factors play
a decisive role in IT in various types of forest. In open felled areas, the determining factor is PAR (0.81, p < 0.05) and, to
a lesser extent, atmospheric temperature (0.69, p < 0.05), and under the canopy - only PAR (0.96, p <0.05). A decrease
in IT and, accordingly, photosynthesis leads to a decrease in the population’s vitality and non-ripening of seeds, which is
an ecophysiological factor of the heather absence south of Kurgan city.

Published: February 2024

Optical methods and optical properties are usually used to research the structure of wood and its ring structure. However, these properties are not directly related to its mechanical and other physical characteristics. To study them, methods of x-ray densitometry, synchrotron radiation, nuclear magnetic resonance, etc., which are not very common in wood science, are used. These methods are quite labor-intensive and require expensive equipment. In this regard, there is a need to develop simple and convenient means and methods for studying the micromechanical properties of wood. The main goal of the work is to develop such an approach using nanoindentation and digital scratching of a cross section of wood and to identify its potential in the further development of dendrochronology and related disciplines. Using the NI method, radial dependences of hardness H and Young's modulus E were obtained for eleven consecutive annual pedunculate oak (Quercus robur L.) wood rings for 3 different loads Pmax = 2, 100 and 500 mN. The values of H in the range from 70 to 340 MPa and Young's modulus E in the range from 2 to 10 GPa were determined for the corresponding loads and early (EW) and late wood (LW). Using the scratch test method, profiles of the normal force Fn and the corresponding hardness HS (in the range from 53 to 225 MPa) were obtained for the period 2007-2020. According to both methods, the widths of annual rings were determined; the discrepancy between the values and the optical method was < 3 %.
About the best geoecotypes of Scots pine (Pinus sylvestris L.) for artificial reforestation
Authors: Mihaylova Mariya , Chernyshov Mikhail , Rabko Siarhei
Published: February 2024

The basis for adjusting the previously established boundaries of forest seed areas for forest-forming species are the results of studying the condition, growth intensity and productivity of their offspring in the form of forest geographical crops, which were created in the 60-70s of the XX century in different regions of the USSR. The best geoecotypes are identified by comparing the morphometric parameters achieved by the test geographical offspring by the age of “ripening”, or on the basis of multifactor analysis with their comprehensive assessment based on a set of criteria. In 2018-2021 In order to identify and select the best geoecotypes of Scots pine (Pinus sylvestris L.), moved to the Central Black Earth Region (Voronezh region), based on their potential economic suitability for sustainable forest reproduction in the European part of the Russian Federation, comprehensive studies were carried out in 59-61-year-old tree stands that are seed trees offspring of different forest-steppe and steppe geoecotypes. On 32 trial plots, promising, medium and unpromising P. sylvestris geoecotypes were determined using a unified methodology and 12 evaluation criteria. It has been reliably established that among the 18 forest-steppe ecotypes studied, only 4 are the best. To introduce them into silviculture production, it is necessary to optimize the logistics of procuring seeds of the best ecotypes, growing standard planting material from them and planting them in appropriate forest conditions. According to forecasts, the use of seeds and planting material, identified selectively the best geoecotypes of P. sylvestris during the implementation of plans for the sustainable reproduction of future forests in the European part of the Russian Federation, will provide an accumulative silvicultural and economic effect that grows over time and high economic efficiency.
Noise filtering of the forest site scanned by LiDAR based on YCbCr and L*a*b* color models
Authors: Rogachev Dmitriy , Kozlov Ivan , Klubnichkin Vladislav
Published: February 2024

Point clouds are widely used in ground-based forest scanning using LiDAR and stereo cameras. Point clouds
often suffer from noise outliers and artifacts that distort data. Hardware accuracy and quality of the initial point cloud
during ground scanning of a forest area can be improved by using scanners with higher expansion, as well as using
photogrammetry or additional sensors. To eliminate noise, software methods can be used: point filtering, smoothing,
statistical methods and reconstruction algorithms. A new approach to filtering the noise of the scanned forest area is based
on the analysis of the values of the color components in the YCbCr- and L*a*b- spaces. The properties of the YCbCrand L*a*b-color models were investigated and threshold values for classifying points as noise or object depending on
their distance to the centroids were determined. The use of a combined (YCbCr | L*a*b) filter on the point cloud reduced
the number of points to 38 963 (17.41% of the original number). When calibrating the camera and LiDAR based on the
(YCbCr | L*a*b) filter, the total average value of translation errors was 0.0247 m, rotation 6,244 degrees, reprojection
8,385 pixels. The noise-filtering method (YCbCr | L*a*b) shows high accuracy and reliability in removing noise and
maintaining the integrity of objects in the point cloud, which will allow the data obtained on unmanned machines to be
used later when performing logging operations.
Investigation of adhesive bond strength when facing furniture boards with flexible stone veneer
Authors: Ponomarenko Larisa , Kantieva Ekaterina , Kireeva Anastasiya
Published: February 2024

Stone veneer has been known for a long time. But mostly it has been used as a finishing material, which is widely
applied in decorating the outer surfaces of buildings and facilities. Stone veneer is a thin cut of natural stone - slate, which
is applied to fiberglass or textiles. The thickness of the veneer is in the range of 2-3 mm. Stone veneer is available in the
form of rolls or tiles. Due to its flexibility, it can be used to refine surfaces that have angles and small radius of curvature.
The flexibility of stone veneer is a unique property, since natural stone is not flexible. In today’s world stone veneer is
trying to find new fields of application. This material is used not only in interior and exterior designs, but also as a
decorative coating of furniture panels. In this work we have established the possibility of wood board materials facing by
stone veneer using standard technologies and the most common adhesives used in our country, such as urea-formaldehyde
resin and polyvinyl acetate dispersion.

Bridging the Gap from the Other Side: How Corpora Are Used by English Teachers in Norwegian Schools
Authors: Kavanagh Barry
Published: February 2024

Researchers have written of ‘bridging the gap’ between corpus linguistics and teaching practice. This study focuses on in-service English teacher informants from Norwegian schools, to try to address the ‘gap’ from the teaching practice ‘side’, rather than from the linguist ‘side’ engaged in spreading corpus linguistics. The study collects data on teachers’ familiarity with corpus linguistics, what corpora are used for and how, and teachers’ views on the obstacles to corpus use. The research question is How are corpora used by in-service English teachers in Norwegian schools? The research design consists of an online questionnaire and follow-up interviews. The questionnaire was answered by 210 teachers, 34 of whom answered they had done some work with corpora. The interviews were with three corpus-using teachers. The corpora they used were GloWbE, SkELL, Netspeak and COCA. Teacher-corpus interaction was for reference and for creating vocabulary and varieties of English exercises, and pupil-corpus interaction was encouraged by two of the teachers. The obstacles to the use of corpora were identified as differences between school levels, usability, and lack of teacher need. In concluding remarks, it is suggested that a starting point for corpus use among teachers may be to teach the tools and methods that seem to be already working for in-service teachers.
From Racial Difference to Racial Indifference: The Neo- Liberal Narrative and Its Colonial Legacy Through the Example of Washington Black (2018) by Esi Edugyan
Authors: Frątczak-Dąbrowska Marta
Published: February 2024

The present article centres on Washington Black—a neo-slave narrative whose eponymous hero documents his route from slavery to freedom. The novel offers insight into how the structural legacy of colonialism lives on in (neo-)liberalism, which is understood here as a currently dominant socio-economic system and a set of beliefs rooted in the colonial economy and colonial ideology. The paper investigates how harmful discursive formations once created to justify European civilizing missions and chattel slavery are still being used to belie the reality of structural violence and systemic inequity, where particular groups are being racialised and marginalised at the same time. Through the prism of the novel, the article looks at how the discourse of universal human rights, the idea of a grateful slave, and the myth of self-sufficiency may be employed as the mechanisms of social control over the Other.
Critical Thinking and English Literature in Higher Education: The Theoretical Models and the Swedish Syllabi
Authors: Cananau Iulian
Published: February 2024

Critical thinking is an ever-growing interdisciplinary field of research. This paper introduces key aspects of the vast scholarship on critical thinking in higher education to the academic community of English literary studies in Sweden. Its aim is to provide a sound framework for research-based discussions of the potential for critical thinking in literature courses. To achieve this goal, the paper first presents a synopsis of the main theoretical models of critical thinking in higher education: as cognitive-argumentative skills, as cognitive-argumentative skills and psychosocial dispositions, as resistance to oppression, and as a crucial step toward critical acting and being. These models and approaches are then used to identify the conceptions of critical thinking that inform the learning objectives in undergraduate-level English literature syllabi in Sweden. The study finds that the cognitive-argumentative-skills approach dominates the conceptualization of critical thinking in English literature syllabi, but the other three models are also present in various degrees. The article ends with a call for a systematic discussion of the curricular and teaching practices that cultivate critical thinking in English literary studies.

The Outcomes of Trabeculectomy following Anti-VEGF Treatments in Neovascular Glaucoma : A Systematic Review and Meta-Analysis
Authors: Dewi Ni Putu Ayu Pande Arista
Published: February 2024

Introduction

Neovascular glaucoma (NVG) is a secondary glaucoma that potentially causes blindness due to proliferation of fibrovascular tissue in the anterior chamber angle. Ischemia in retinal triggers a cascade of various angiogenic factors including vascular endothelial growth factor (VEGF) and interleukin-6 which lead to neovascularization. It was known that anti-VEGF inhibits the primary mediators of neovascularization and control intraocular pressure (IOP) in NVG.

Objective

To summarize outcome of anti-VEGF with trabeculectomy and applied in clinical practice.

Methods

PRISMA guideline was followed and analyzed the comparison with Revman (version 5.4). We used databases and professional websites published on eye conditions between 2013-2023 in English. All interventional and observational studies with 95% confidence interval (CI) were used. Risk of bias was measured using funnel plot. Outcomes measured were IOP, Best Corrected Visual Acquity (BCVA), neovascularization iris (NVI) recurrence before and after trabeculectomy.

Result

Six studies (199 eyes) showed a significant difference in IOP (MD=25.84, 95%CI 24.08-27.60, p< 0.00001) and NVI recurrence (RD=0.94, 95%CI 0.86-1.01, p<0.00001). While four studies (143 eyes) found there was a significant difference in BCVA (MD=0.21, 95%CI 0.06-0.37, p=0.008). The result of NVI should be interpreted with caution and not considered as definitive statement since the data was moderately heterogenic (I2=68% p=0.009).

Conclusion

It could be concluded there was a significant difference in IOP, BCVA, and NVI recurrence after given anti-VEGF with trabeculectomy. We could not conclude which anti-VEGF gave better result since there were lack of studies, low of studies quality, and heterogen data for NVI recurrence.

In cases of diabeticmacular edema (DME), loading dose is a critical phase to achieve a stable concentration ofintravitreal vascular endothelial growth factor (VEGF) in order to prevent progressivity. This studyaims to determine the demographic and clinical characteristics, waiting time, compliance, as well asthe relationship between education, domicile and clinical outcomes to compliance during loadingdose in DME patients.
MethodsIn this retrospective descriptive study, we reviewed medical records of DME patients who receivedanti-VEGF intravitreal injection between 1 January 2019 and 31 December 2020, while alsocomparing records in 2019 (pre-Covid-19) and 2020 (during Covid-19).
ResultsThere were 160 patients (207 eyeballs) in 2019 and 83 patients (114 eyeballs) in 2020 who receivedloading dose with similar profiles of sex, age, education, initial visual acuity and central macularthickness (CMT). Median waiting times in 2019 and 2020 were 19 days and 23.5 days, respectively(p=0.016). Only 25 (30.5%) and 15 (35.7%) patients were punctual in 2019 and 2020, respectively.There was no significant relationship between education and domicile with compliance (p= 0.45, p=0.51). Furthermore, there were visual acuity improvements of -0.18 logMAR and -0.0 logMAR in thepunctual and unpunctual group, respectively, as well as CMT decrease of -181 ?m and -156 ?m,respectively.
ConclusionMost patients who received loading dose were unpunctual. There was no significant relationshipbetween education and domicile with compliance. Furthermore, there were more significantimprovements in clinical outcomes among the punctual patients.

Introduction & ObjectivesTo analyze relationship between mean deviation (MD) slope with related risk factors and fovealsensitivity of Humphrey field analyzer (HFA) in open angle glaucoma.

Patient and MethodsThis study was retrospective and consecutive sampling during a year follow up period in SardjitoGeneral Hospital. A total 95 eyes from 95 patient were exemained the MD slope by HFA (SITAstandard, 24-2 program) being follow up and compared first examination with the final VF test.Relation of MD slope with risk factors and HFA parameters were correlatively analyzed.

ResultsMean Deviation slope was observed in 48/95 patients (50.52 %) and no progression was observed in47/95 patients (49.47 %). The related risk factors gender, age, spherical equivalent and IOP do notshowed significant correlation with MD slope (R= 0.02, P= 0.89), (R=0.10, p=0.47), (R=-0.27, p=0.06) and (R=-0,13, p= 0.35). Foveal sensitivity test in HFA parameter do not showed significantcorrelation with MD slope (R= 0.14, p=0.32).

ConclusionWorsening value of spherical equivalent and IOP showed negative correlation to MD slope, butstatistically do not showed significant correlation caused there are not much differences betweenprogress and non progress group.

Introduction & ObjectivesBrolucizumab is the newest anti-vascular endothelial growth factor (anti-VEGF). It showed superioranatomic outcomes and noninferiority best corrected visual acuity (BCVA) results for Wet Aged-Related Macular Degeneration (Wet-AMD) compared to other anti-VEGF. In Yogyakarta, it's beenonly used in a few patients and we want to report the effectiveness and safety of brolucizumab inWetAMD

MethodsIn this retrospective study, all wetAMD patients who underwent Brolucizuab intravitreal injectionsbetween December 2021 and January 2023 at Dr YAP Eye Hospital were studied. Patient’sdemographic data, before and after intravitreal brolucizumab injections (central macular thickness,intraocular pressure, and BCVA) were assessed.

ResultsThis study included 6 eyes of 6 patients (3 women) with a mean age of 69.5 years old. The meanfollow-up period was 27 ± 10.1 weeks after the first injection of brolucizumab. Three patients werenaïve wetAMD patients, three anti-VEGF experienced wetAMD patients. The mean BCVA at baseline(before brolucizumab injection) was 0.12 decimal (6/48) and 0.29 decimal (6/20) at the last followup.Five out of six patients' visual acuity were improved. In four out of six patient central macularthickness were reduced (mean difference 29,2 um). None of the patient's intraocular pressureincreased over 21 mmHg. None of the patients reported any signs of inflammation, vasculitis, ocularor systemic adverse effects.

ConclusionThis limited data demonstrated that brolucizumab was relatively safe and effective in stabilizingBCVA for both WetAMD patients who had previous treatment with other anti-VEGF agents andnaive. Larger sample sizes studies & future multicenter collaborative are warranted

Published: February 2024

Introduction & ObjectivesPrimary open angle glaucoma (POAG) is a chronic optic neuropathy characterized by slowlyprogressive visual function loss. Platelet activation as well as its interaction with vascularendothelium and plasma components, play an important role in the vascular pathophysiology ofPOAG. Platelet aggregation in glaucoma tends to increase. This change has negative impact on smallvessel circulation in the eye, such as branches of short ciliary arteries supplying the optic nerve. Inthis study, we will assess the correlation between platelet parameters and the severity of POAG.

MethodsThis study is an analytical observational study. Data were obtained retrospectively and prospectivelywith a cross sectional study approach conducted at Sanglah Hospital, Denpasar. The study samplewas 62 eyes selected consecutively. Data was analyzed using SPSS. Descriptive data presentednumerically or categorically, bivariate analysis using Pearson and Spearman correlation tests andmultivariate analysis using logistic regression.

ResultsResults showed that the mean age of the research subjects was 66.71 ± 9.795 years, with themajority was male (70.6%). Bivariate analysis, showed no significant correlation between plateletparameters (PLT, PDW, MPV) and the severity of POAG. Multivariate analysis found that age ? 68years, 9,850 times more likely to develop moderate to severe glaucoma, compared to patients < 68years old (OR 9,850, 95% CI, p = 0.009).

ConclusionPlatelet parameters showed no significant correlation with the severity of POAG, meanwhile olderage is more at risk of developing moderate to severe POAG.

Published: February 2024

Background: Receptor advanced glycation end products (RAGE) activation plays an essential role in diabetic retinopathy (DR) progression. This study was aimed to explore the role of anti-RAGE antibodies (RAGE antagonists) in inhibiting DR progression through their hypoglycemic and anti- inflammatory mechanism in diabetic retinopathy induced rats.

Methods: A total of 30 male Wistar rats were randomly divided into five group. The group was consisted of normal control group, DR group without treatment, DR group with anti-RAGE 1 g/kg BW, 10 g/kg BW, and 100 g/kg BW. To assess the diabetic retinopathy, fundus photographs were taken every week using a camera with 16x magnification placed in front of the rat's eyes. Blood glucose was checked by the glucose oxidase-peroxidase method. Retinal TNF-? levels and VEGF were examined using an enzyme-linked immunosorbent assay (ELISA) kit.

Results: The finding of this study showed that anti-RAGE treatment at dose of 10 and 100 g/kg BW, HbA1c levels were significantly higher (p< 0.05) compared to the normal control group but significantly lower (p< 0.05) than in the diabetes group. The mean blood vessel diameter in the DR+anti-RAGE 10 and 100 g/kg BW groups was significantly lower than in the diabetic retinopathy group (p< 0.05). The administration of anti-RAGE 10 and 100 g/kg BW showed the ability to significantly reduce VEGF levels compared to the DR group (p< 0.05).

Conclusions: This study revealed at doses of 10 and 100 g/kg BW, anti-RAGE antibodies improved diabetic retinopathy in Wistar rats through hypoglycemic effects and anti-inflammatory mechanisms.

A espatódea, é uma árvore de origem do oeste da África, muito utilizada para ornamentação, com florescimento amplo no verão e outono, com flores atrativas a abelhas, beija flores e outros insetos, porém seu néctar é considerado tóxico podendo ocasionar mortes de abelhas e outros polinizadores, quando há escassez de outras floradas, o que ocorre principalmente no final do outono e início do inverno, na região sul. Em 2019 a Assembleia Legislativa de Santa Catarina aprovou a Lei 17.694, que, “Proíbe a produção de mudas e o plantio da Spathodea campanulata”. Com o objetivo de registrar a ocorrência de espatódea no município de Santa Rosa do Sul, durante o processo de registro foi realizada a divulgação da lei para a população, com a orientação da substituição destas arvores por espécies nativas. Foi detectado a presença de 93 árvores de espatódea, com grande concentração na sede do município, e o desconhecimento da população quanto a legislação vigente.

Artista plástica que propõe argumentos subjetivos na realização / construção de suportes para as artes, no propósito ou ideia do objeto real, ou seja, uma performance onde o corpo morfoseia-se na mistura, fusão em ser e ter, versus artista e obra, no sistema de referência dos valores de materiais apropriados através da objetivação e singularidade que se manifestam em objetos destinados pela diferenciação de aspectos ou pelos hábitos. Com o objeto “original” que se constrói em algo “coisa”, a artista, com o fogo em punho, propõe o lanças chamas que executa, derrete e o transforma, no sentido da phronesis (heideggeriana). Involuntariamente ou intencional propõe esse “algo” almejada em criação.
