Using a dual-tree complex wavelet transform for denoising an optical coherence tomography angiography blood vessel image
Authors: Liu Huazong , Lin Shenghao , Ye Chong , Yu Dan , Qin Jia , An Lin
Published: September 2020

High image quality is of great importance for precise diagnosis and therapeutics of eye disease in clinic. A human retina OCT angiography (OCTA) image can be extracted from multiple OCT B-scans to visualize the distribution of blood vessels. However, OCTA suffer from the degeneration of image quality due to inherent Gaussian noise of the OCT system while the blood vessel’s signal is extracted. The degeneration of the noise in OCTA image will be more conducive to the evaluation of abnormal and normal blood vessels in the human eye. To precisely assist diagnosis and therapeutics in clinic by reducing the Gaussian noise in the OCTA image, an OCTA image denoising method is proposed based on the dual-tree complex wavelet transform and bilateral shrinking Bayes frame. Initially, OCTA images are extracted from the raw data based on the optical microangiography algorithm. Then, the image is decomposed into the wavelet domain using the dual-tree complex wavelet transform. The signal and noise among different wavelet scale layers are separated on the basis of the Bayesian posterior probability. Finally, the inverse wavelet transform is employed to reconstruct the denoised image. Through the noise reduction process of the algorithm, the PSNR and CNR of the OCTA image are increased by 49.15% and 47.91%, respectively. According to the results, the wavelet transform can effectively separate the blood flow signal and noise in processing the OCTA signal, which will provide an effective image processing method for the clinical evaluation requiring high-quality OCTA images.
Expression of p11 and Heteromeric TASK Channels in Rat Carotid Body Glomus Cells and Nerve Growth Factor–differentiated PC12 Cells

Published: September 2020

TWIK-related acid-sensitive K+ (TASK) homomeric channels, TASK1 and TASK3, are present in PC12 cells. The channels do not heteromerize due plausibly to a lack of p11 protein. Single-channel recording reveals that most of the rat carotid body (CB) glomus cells express heteromeric TASK1-TASK3 channels, but the presence of p11 in glomus cells has not yet been verified. TASK1, but not TASK3, binds to p11, which has a retention signal for the endoplasmic reticulum. We hypothesized that p11 could facilitate heteromeric TASK1-TASK3 formation in glomus cells. We investigated this hypothesis in isolated immunocytochemically identified rat CB glomus cells. The findings were that glomus cells expressed p11-like immunoreactive (IR) material, and TASK1- and TASK3-like IR material mainly coincided in the cytoplasm. The proximity ligation assay showed that TASK1 and TASK3 heteromerized. In separate experiments, supporting evidence for the major role of p11 for channel heteromerization was provided in PC12 cells stimulated by nerve growth factor. p11 production took place there via multiple signaling pathways comprising mitogen-activated protein kinase and phospholipase C, and heteromeric TASK1-TASK3 channels were formed. We conclude that p11 is expressed and TASK1 and TASK3 heteromerize in rat CB glomus cells.
Interviewing the musical sample
Authors: Groten Sean
Published: September 2020

Digital technologies and Musical Instrument Digital Interface-sampled instruments have emerged as one of the most significant technological shifts in musical consciousness in western society. Digital music has introduced new epistemologies of music as it raises questions of authorship and creativity, while also challenging the ontological presumptions about what it means to be a musician. Through interviewing the sample by applying various posthuman heuristics, I explore my own relationship to digital music samples and sampling technology as a composer and musician. I engage in a phenomenological inquiry that surveys the various ways the sample affects my ecological milieu of music-making, and more broadly, I explore how a musician is at all times enacting an intra/actional relationship as negotiated between themselves and their instrument.
Accountabilities of posthuman research
Authors: Thompson Terrie Lynn , Adams Catherine
Published: September 2020

What constitutes ‘good’ posthuman research? This article offers three dynamics to help assess the value of posthuman-inspired inquiry. We propose that a good posthuman research account should show evidence that the researcher: (1) attended to their own more-than-humanness and made explicit how they interviewed and attuned to the nonhuman things of their inquiry; (2) reassembled resemblings of the posthuman world by inventively weaving and fusing human and nonhuman storylines; and (3) offered analytic insights into the liveliness of posthuman research work as the performativity of difference.
Regional screen ecosystems at the peripheries: Production and talent development in Tromsø and Aarhus
Authors: Chow Pei-Sze , Sand Stine Agnete
Published: September 2020

This article addresses the regionalization of screen culture in Norway and Denmark, focusing on how regional screen entities in Tromsø and Aarhus are working to professionalize production and talent development at the peripheries of both countries. We outline their distinctive characteristics and circumstances as regional hubs and delineate the key actors that constitute the respective screen ecosystems. We focus on the interplay between regional film policy, production and talent development in relation to regional development, geography, creativity, innovation and the economy of culture. Based on an examination of policies, strategy documents and interviews conducted with practitioners in Aarhus and Tromsø over the period 2014–19, we explore the diverse strategies these regional production hubs employ to develop and – more challengingly – retain talents in the region, arguing that despite the increased attention given to ‘diversity’ in film policy, structural and cultural obstacles hamper sustainable growth.

Authors: Colkesen Ismail , Ertekin Omer Habib
Published: September 2020

In this study, the performances of random forest (RF), rotation forest (RoF), and canonical correlation forest (CCF) algorithms were compared and analyzed for classification of hyperspectral imagery. For
this purpose, the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) Indian Pine (IP), the Reflective Optics System Imaging Spectrometer University of Pavia, and the AVIRIS Kennedy Space Center (KSC) data
sets were used as main data sources. In addition to the confusion matrix–derived accuracy measures (overall accuracy, kappa coefficient, F-scores), the performances of the algorithms were analyzed in detail considering three diversity measures (Q statistics, correlations, and interrater
agreements) and a kappa-error diagram. Results showed that the highest classification accuracies (87% for IP, 94% for PU, and 93% for KSC data sets) were achieved with the use of CCF algorithm, and improvements in classification accuracy were statistically significant compared to RF and RoF.
Based on the diversity measures and the kappa-error diagram, individual learners in the CCF ensemble were found to be more diverse and accurate.

Published: September 2020

O fenômeno da alta concentração de terras, em grande parte, pode ser explicado pela história agrária de um país. A posse e uso da terra no Brasil e na Bahia revela o antagonismo suscitado pela subordinação, expropriação e exploração entre uma classe social dominante representada pelos proprietários de terra e os camponeses, o que incita a realização de uma análise contextualizada sobre a atual estrutura fundiária brasileira. Neste contexto, este trabalho faz uma análise da atual estrutura fundiária da Bahia, por meio da aplicação do índice de Gini (IG) para a terra e da técnica de agrupamento espacial (clusters), para os anos censitários de 2006 e 2017 dos 417 municípios baianos. Conforme os resultados obtidos através do cálculo do IG e da classificação utilizada, identificou-se significativa concentração fundiária na Bahia entre 2006 e 2017, muito embora tenha apresentado moderada redução nessa concentração. De acordo com a análise espacial, há formação de agrupamentos com alta concentração, especialmente em municípios da Região Geográfica Intermediária de Barreiras e a formação de clusters de municípios com baixos valores do IG nas Regiões Geográficas Intermediárias de Guanambi e Vitória da Conquista. As análises revelam que há relação entre concentração fundiária e condições socioeconômicas das regiões.

The lack of mastery of mufradāt is one of the factors of the difficulty in mastering language skills, and Madrasah in particular does not have material specifically devoted to mufradāt. Mufradāt is taught along with language skills. This is intended to help students focus on the mahārah which must be mastered. This article aims to increase the understanding and mastery of mufradāt in Madrasah Aliyah in grade 11 of MAN 2 Padang Religious Program. The problem that arises in this school is the lack of mastery of mufradāt  in students which makes it difficult for them to understand teaching materials. Based on that, this research is limited to three important points; the technique of using film media in learning  mufradāt,, the levels of students' mastery of  mufradāt  before the action, and the level of mastery of students in mufradāt  after the action. The study used classroom action research method which is carried out in two cycles. The results of the study show that the steps in using film media have several points, giving a list of mufradāt, watching the film, reading the text hiwār from the film, giving difficult vocabulary and test. In the first cycle the value of students previously 66% to decreased to 58.37%, while in the second cycle increased to 86.46%.

Isso vem do fato de sermos um país de língua portuguesa, perdido num oceano de língua espanhola. Para piorar, nosso tamanho territorial não nos permite viajar com facilidade para outros países, para aprender sua cultura, e sentir a necessidade de aprender, afinal, outras línguas.

A New Direct Tension Test Method for Soils and Soft Rocks
Authors: Li Yanrong , Guan Fanfan , Su He , Aydin Adnan , Beroya-Eitner Mary Antonette , Zachert Hauke
Published: September 2020

Tensile strength plays a crucial role in many engineering activities involving soils and soft rocks. Currently, several methods for tensile strength determination exist, the most common of which include the direct tension method, Brazilian test, ring test, axial fracturing test, bending test, and hydraulic fracturing test. However, outstanding problems associated with these methods, e.g., undesirable eccentric forces and damage of specimen ends, significantly affect obtained tensile strength values. To overcome these problems, we propose an alternative direct tension test method together with the newly developed apparatus. The proposed method uses an annular specimen that is tension-loaded on the inner hole. The method was evaluated through a series of tests on undisturbed soil and remolded gypsum-sand mixture specimens. For validation, comparison of results between the proposed method and the International Society for Rock Mechanics (ISRM)-suggested method was performed. Based on the results of the experimental program, the proposed method is considered more capable of and more suitable for determining the tensile strength of soils and soft rocks than the ISRM-suggested method.
Developmental Phase Transitions in Spatial Organization of Spontaneous Activity in Postnatal Barrel Cortex Layer 4

Published: September 2020

Spatially-organized spontaneous activity is a characteristic feature of developing mammalian sensory systems. However, the transitions of spontaneous-activity spatial organization during development and related mechanisms remain largely unknown. We reported previously that layer 4 (L4) glutamatergic neurons in the mouse barrel cortex exhibit spontaneous activity with a patchwork-type pattern at postnatal day (P)5, which is during barrel formation. In the current work, we revealed that spontaneous activity in mouse barrel-cortex L4 glutamatergic neurons exhibits at least three phases during the first two weeks of postnatal development. Phase I activity has a patchwork-type pattern and is observed not only at P5, but also P1, before barrel formation. Phase II is found at P9, by which time barrel formation is completed, and exhibits broadly synchronized activity across barrel borders. Phase III emerges around P11 when L4-neuron activity is desynchronized. The Phase I activity, but not Phase II or III activity, is blocked by thalamic inhibition, demonstrating that the Phase I to II transition is associated with loss of thalamic dependency. Dominant-negative (DN)-Rac1 expression in L4 neurons hampers the Phase II to III transition. It also suppresses developmental increases in spine density and excitatory synapses of L4 neurons in the second postnatal week, suggesting that Rac1-mediated synapse maturation could underlie the Phase II to III transition. Our findings revealed the presence of distinct mechanisms for Phase I to II and Phase II to III transition. They also highlighted the role of a small GTPase in the developmental desynchronization of cortical spontaneous activity.

SIGNIFICANCE STATEMENTDeveloping neocortex exhibits spatially-organized spontaneous activity, which plays a critical role in cortical circuit development. The features of spontaneous-activity spatial organization and the mechanisms underlying its changes during development remain largely unknown. In the present study, using two-photonin vivoimaging, we revealed three phases (Phases I, II, and III) of spontaneous activity in barrel-cortex layer 4 (L4) glutamatergic neurons during the first two postnatal weeks. We also demonstrated the presence of distinct mechanisms underlying phase transitions. Phase I to II shift arose from the switch in the L4-neuron driving source, and Phase II to III transition relied on L4-neuron Rac1 activity. These results provide new insights into the principles of developmental transitions of neocortical spontaneous-activity spatial patterns.

Published: September 2020

Seed priming may improve germination performance of rice under drought. The present study was conducted to investigate the dynamics of seed biochemical changes during priming and post-priming germination under drought and to correlate those biochemical properties with the germination
performance of primed seeds. The priming treatments were non-priming as control, hydro-priming and osmo-priming at -0.3, -1.0 and -2.2 MPa. All seeds were germinated under different levels of drought stress: 0 MPa as control, -0.2, -0.4, -0.6 and -0.8 MPa. The germination performance of hydro-
and osmo-primed seeds at -0.3 and -1.0 MPa under severe stress (-0.8 MPa) was better compared with control and osmo-primed seeds at -2.2 MPa. Hydro-priming and osmopriming at -0.3 MPa significantly improved germination performance while germinated seeds of -1.0 MPa osmoprimed seeds recorded
the highest root and total seedling length. Proline accumulation was significantly higher in seeds that were hydro-primed or osmo-primed at -0.3 or -1.0 MPa as compared with non-primed control seeds and seeds osmo-primed at -2.2 MPa. In addition, proline was significantly correlated with the
starch and glucose content and α-amylase activity. Higher α-amylase activity would accelerate the process of starch hydrolysis into soluble sugar for embryo growth and development resulting in enhanced germination processes.

The pituitary gland functions as a prominent regulator of diverse physiologic processes by secreting multiple hormones. Circular RNAs (circRNAs) are an emerging novel type of endogenous noncoding RNA that have recently been recognized as powerful regulators participating in various biological processes. However, the physiological roles and molecular mechanisms of circRNAs in pituitary remain largely unclear. Herein, we concentrated on expounding the biological function and molecular mechanism of circRNA in rat pituitary. In this study, we identified a novel circRNA in pituitary tissue, circAkap17b, which was pituitary- and stage-specific. Then, we designed circAkap17b siRNA and constructed an overexpression plasmid to evaluate the effect of loss- and gain-of-circAkap17b function on FSH secretion. Interestingly, silencing circAkakp17b significantly inhibited FSH expression and secretion, while overexpression of circAkap17b enhanced FSH expression and secretion. Furthermore, dual luciferase reporter and RNA immunoprecipitation (RIP) assays confirmed that circAkap17b could serve as miR-7 sponge to regulate target genes. Additionally, miR-7b suppressed FSH expression and secretion by directly targeting Fshb through the dual luciferase reporter and RT-qPCR analysis. Additionally, rescue experiments showed that circAkap17b could regulate FSH secretion in pituitary cells through a circAkap17b-miR-7-Fshb axis. Collectively, we demonstrated that circAkap17b could act as a molecular sponge of miR-7 to upregulate expression of the target gene Fshb and facilitate FSH secretion. These findings provide evidence for a novel regulatory role of circRNAs in pituitary.
NETosis contributes to the pathogenesis of diabetes and its complications

Published: September 2020

NETosis, a novel form of neutrophil-related cell death, acts as a major regulator of diabetes and diabetes-associated complications. In this review, we show that the extrusion of neutrophil extracellular traps, termed NETs, plays an important role in the pathogenesis of type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), and diabetes-induced complications. In T1DM, β-cell death induces the sequestration of neutrophils in the pancreas and seems to be correlated with increased NETosis. In T2DM patients, products of NETs release are significantly elevated. Increased levels of dsDNA are correlated with the presence of cardiovascular disease and diabetic kidney disease, further supporting the role of NETosis in the pathogenesis of other diabetes-induced complications such as impaired wound healing and diabetic retinopathy. NETosis is induced by high glucose through incompletely understood mechanisms, but it also appears to be elevated in patients with diabetes who have tightly controlled glucose levels. We hypothesize that hyperglycemia worsens the already elevated baseline of NETosis in diabetic patients to further increase its detrimental effects.
Animal models of human pregnancy and placentation: alternatives to the mouse
Authors: Carter Anthony M
Published: September 2020

The mouse is often criticized as a model for pregnancy research as gestation is short, with much of organ development completed postnatally. There are also differences in the structure and physiology of the placenta between mouse and human. This review considers eight alternative models that recently have been proposed and two established ones that seem underutilized. A promising newcomer among rodents is the spiny mouse, which has a longer gestation than the mouse with organogenesis complete at birth. The guinea pig is also recommended both because it has well-developed neonates and because there is a wealth of information on pregnancy and placentation in the literature. Several smaller primates are considered. The mouse lemur has its advocates yet is less suited as a model for human pregnancy as its young are altricial, placentation very different from that of humans, and husbandry requirements not fully assessed. In contrast, the common marmoset, a New World monkey, has well-developed neonates and is kept at many primate centres. Marmoset placenta has some features that closely resemble human placentation, such as the interhaemal barrier, although it is uncertain if invasion of the uterine arteries occurs in this species. In conclusion, pregnancy research would benefit greatly from increased use of alternative models such as the spiny mouse and common marmoset.

The Cellulose synthase-like (Csl) F family has been considered as one of the most crucial genes regulating β-glucan synthesis. It is a cereal cell wall component, holding advantages for human nutrition, but disadvantages in animal nutrition, malting and brewing industries. Based on a genome-wide search method, present study identified barley CslF gene family members by considering the importance of (1,3;1,4)-β-D-glucan and newly completed barley genome. A sum of Eighteen CslF genes were recognized in the barley genome.  Then, phylogenetic analyses classified them into 3 groups, that shared conserved motif compositions. A new motif, D,D,WQxxD was also found, which was responsible for the cellulose synthase. Furthermore, using RNA-seq data,  the HvCslFs expression profiles were systematically examined in different tissues and tissue-specific candidates were found. Lastly, interaction network analysis identified 11 CslF genes involved in the interaction network. All together, prsent task provides valuable evidence about the genomic organization and evolutionary relationship of the CslF gene family in barley, and facilitate the functional surveys of CslF genes in barley and beyond.

Globodera rostochiensis (Cyst nematode-DDH1) is a major pathogen of potato, this type of nematode was recently reported in Egypt in 2017 as a serious plant pathogen especially in Alexandria and El-Behera governorates. This study aimed to identify this species (G. rostochiensis) on the molecular level in addition to examine the plant-cyst nematode interaction. The results of ITS-PCR showed two bands with molecular sizes 238 bp and 370 bp. The small band is identified as internal band for the large one. The sequence analysis was conducted on 238 bp amplicon and the results obtained confirm that the obtained DNA sequence belong cyst nematodes (G. rostochiensis) with similarity 77%. The constructed phylogenetic tree based on the DNA nucleotide sequence showed close relationship with a Japanese G. rostochiensis (AB207271). The functional transcriptome of the infected and non-infected potato plants was analyzed using Differential Display- PCR technique and about 57 up regulated and 22 down regulated genes. Seven genes (2 downregulated and 5 upregulated) were chosen at random and sequenced. The nucleotide sequences observed that the two down regulated genes were; Chitinase domain containing protein 1 and N-like putative resistance protein. Whereas, the five up regulated genes were; Glucan endo 1,3 beta glucosidase A precursor, STS 14 protein gene, Phytoalexin deficient 4-1 protein gene, PEN1 gene and Linoleate 13S lipoxigenase 2-1, chloroplastic like, respectively. We can concluded that the regulation changes occurred for some pathogen related genes in systemiclly acquired immunity of infected potato plant compared with control were the main observation. Moreover, the cyst nematode could be able to suppressd some of plant defense system genes and inducing another in the same time.

Published: September 2020

Pollution such as water pollution got intensified with an increase in population density. So, it became important to deal with various industrial and household contaminants like dyes, heavy metals, microbes and radioactive materials. Hence, to remediate the water from such hazardous contaminants in a rapidly developing world, new technological inventions are required globally. Nanotechnology is getting increased attention as it is an advanced technology and shows advantages compared to other innovations. Various technologies are available in remediating water such as algal turf systems and nanoparticle-based adsorption. There are several ways of nanoparticle synthesis, but the algae-based synthesis is very significant and environment friendly.  The potential and efficiency of algae in waste water remediation is remarkable and several contaminants can be detoxified, transformed and volatized by algae. There are several potential benefits associated with the algae mediated phycoremediation due to its advantages over conventional systems of remediation and heavy metal removal. Algal strains are easy to culture and adaptive in nature and can be easily manipulated within the laboratory. In this review, we have discussed the biological green nanoparticle synthesis using algae as an eco-friendly, cheap and cost-effective sustainable technology.  However, algal mediated waste water treatment is yet in a primary stage and many innovative steps are necessary for adaptive remediation strategies, which can sustainably address global waste water issues.
Retrospectiva da experiência de gestação de mulheres com depressão pós-parto: estudo comparativo
Authors: Schwochow Monique Souza , Frizzo Giana Bitencourt
Published: September 2020

A sobrecarga emocional própria das vivências do tornar-se mãe pode, freqüentemente, levar ao desenvolvimento da depressão pós-parto. Diante disto, este estudo buscou compreender, de forma retrospectiva, a experiência de gestação de mães com e sem depressão pós-parto. As participantes foram seis mães, com idades entre 28 e 38 anos. Três mães não apresentaram quaisquer transtornos de humor e três tiveram o diagnóstico de depressão pós-parto confirmado. A base para a análise qualitativa desse estudo foi uma entrevista sobre a gestação e o parto.  Os resultados indicaram que a experiência de maternidade tem relação estreita com a forma como as mães lidaram com a necessidade de adaptação frente à maternidade, bem como com o desejo e o planejamento – ou não – da gestação. Os achados apóiam a sugestão da literatura que indica a presença de relatos negativos sobre a experiência de maternidade por mães deprimidas, inclusive sobre a gestação.

Published: September 2020

The construct of self-compassion is based on Buddhist’s teachings on compassion towards oneself. This study provides criterion validity evidence for the Self-Compassion Scale – Brazil. A comparison on self-compassion in Buddhist and Catholic practitioners may contribute to support the Brazilian version of the scale, as well as shed light into religious differences on the matter. Participated in the study 59 Catholics and 59 Buddhists, all self-declared a religious practitioner. We administered a socio-demographic questionnaire and the Self-Compassion Scale – Brazil. Buddhist practitioners presented significantly higher score in self-compassion (M = 4.45, SD = .51) than Catholic practitioners (M = 2.98, SD = .63): t(116) = 13.78, p < .001 (d = 2.56). In addition, there was a significant positive correlation between frequency of religious practice and self-compassion (r = .39, p = .003). Future studies may investigate the relationship between self-compassion and neo-Pentecostal practitioners, which has been increasing in number in Brazil.

Purpose
The purpose of this study was to evaluate the association between HIV status and the presence of chronic health conditions among gay and bisexual men (gbMSM). Most existing on this topic studies fail to account for behavioral factors—such as smoking and alcohol consumption—or focus on the general population without attention to the unique circumstances of gbMSM.
Methods
Sexually active gbMSM, aged >16 years, were recruited using respondent-driven sampling (RDS) between February 2012 and February 2015. HIV serology confirmed the HIV status. Chronic health conditions were classified into one of six broader categories (i.e., cardiovascular, cancer, gastrointestinal, respiratory, mental health, and other). Logistic regression models tested whether HIV status was associated with any of the six categories. All these models used an interaction term between HIV status and age, and adjusted for race/ethnicity, annual income, body mass index, daily smoking, and “risky drinking”.
Results
Overall, 223 HIV-positive gbMSM and 551 HIV-negative gbMSM reported histories of cardiovascular disease (16.1%), cancer (5.1%), gastrointestinal illness (7.2%), respiratory problems (16.1%), mental health conditions (49.2%), and “other” co-/morbidities (13.1%). Compared with older HIV-negative gbMSM, those with HIV were more likely to report cardiovascular (aOR=1.15, 95% CI:1.07, 1.24) and respiratory (aOR = 1.08, 95% CI:1.02, 1.14) disease. There were no differences by HIV status for other co-/morbidities.
Conclusion
Findings support the need for increased resources focused on aging, HIV, and cardiovascular and respiratory health among gbMSM aging with HIV.

Background and objective
Pre-exposure prophylaxis (PrEP) uptake has been suboptimal. Sexually transmitted disease (STD) clinics provide important opportunities to scale PrEP uptake.
Material and methods
To inform the development of a brief intervention to enhance PrEP uptake in STD clinics, we conducted 32 qualitative interviews to explore barriers and facilitators of PrEP uptake among PrEP eligible, PrEP naïve, and men who have sex with men (MSM) presenting for STD screening services. We also solicited input for intervention components to enhance PrEP uptake at STD clinics.
Results
Most participants’ self-perceived HIV risks were low despite reporting unprotected anal intercourse. Many were reluctant to take any medications, expressed apprehension about perceived side effects of PrEP, and were unaware of how to obtain PrEP. Participants recommended that interventions focusing on enhancing PrEP uptake in STD clinics should include: culturally tailored educational materials about PrEP, informational graphics indicating PrEP’s relative efficacy in reducing HIV transmission risks, and comprehensive PrEP navigation. Most participants did not feel strongly about gender, race or ethnicity of providers; however, nearly all preferred gay affirming providers. Brief interventions to enhance PrEP uptake among MSM in STD clinics should include efforts to raise self-awareness of HIV risk, provide information about PrEP’s efficacy relative to other interventions, underscore PrEP’s relatively few side effects, and provide culturally tailored messaging.

Abstract The seed by-products of pequi pulp processing have a kernel in its core which is not used due to the difficulty of its extraction from the spinous endocarp. However, this kernel has high quality oil which can be used for human consumption. Thus, the kernel and the oil composition as well as the conditions to obtain the kernel oil by hydraulic pressing were evaluated in this study. The kernel showed high lipid content (55.76%), therefore being a good source for obtaining oil. The oil extraction by hydraulic pressing presented a higher yield at 5.5 tons to 6.0 tons of force and 9% to 10% moisture. Oil recovery was 75%. The pequi kernel oil showed low acid (0.17 mg KOH/g) and peroxide (1.22 mEq O2/kg) values. The kernel oil also presented high levels of oleic acid (42.47%). The results indicate that the kernel oil extraction is an alternative form for using seeds to increase the producer/processor income and to decrease residue volumes in the pequi processing industry.

ABSTRACT Introduction: simulation based teaching is a powerful tool in medical education, allowing hands on practice under a controlled environment and with repeated maneuvers. Central venous access venipuncture is one of the most frequent procedures carried out in the hospital setting, due to its various clinical indications and, when performed with the help of ultrasonography, the risk of adverse events is minimized. Aim: to develop, to describe and to test a porcine model that simulates the central venous access puncture aided by ultrasonography. Method: a low cost porcine model was developed to train medical students and residents on central venous access guided by ultrasonography. Both students and medical residents underwent a theoretical training regarding the model, followed by a hands-on training session. Afterwards, the participants assessed the model by answering a questionnaire. Results: there were 51 participants. The average score regarding the similarity between the model and the human anatomy was 9.15. When the characteristics were separately assessed, the mean scores regarding the similarity of the vessels, anatomic disposition and ultrasonographic characteristics as well as the venipuncture were, respectively, 9.27; 9.31; 9.54 and 8.86. Conclusion: The model was approved and considered appropriate for the training of central venous venipuncture by all the participants. Furthermore, it is a low cost, simple and reproducible model, that presents high similarity with the human anatomy. Therefore, it may be used as an aid to train people on ultrasonography guided central venous access.

Abstract The aim of this study was to construct a predictive model that uses classification tree statistical analysis to predict the occurrence of temporomandibular disorder, by dividing the sample into groups of high and low risk for the development of the disease. The use of predictive statistical approaches that facilitate the process of recognizing and/or predicting the occurrence of temporomandibular disorder is of interest to the scientific community, for the purpose of providing patients with more adequate solutions in each case. This was a cross-sectional analytical population-based study that involved a sample of 776 individuals who had sought medical or dental attendance at the Family Health Units in Recife, PE, Brazil. The sample was submitted to anamnesis using the instrument Research Diagnostic Criteria for Temporomandibular Disorders. The data were inserted into the software Statistical Package for the Social Sciences 20.0 and analyzed by the Pearson Chi-square test for bivariate analysis, and by the classification tree method for the multivariate analysis. Temporomandibular disorder could be predicted by orofacial pain, age and depression. The high-risk group was composed of individuals with orofacial pain, those between the ages of 25 and 59 years and those who presented depression. The low risk group was composed of individuals without orofacial pain. The authors were able to conclude that the best predictor for temporomandibular disorder was orofacial pain, and that the predictive model proposed by the classification tree could be applied as a tool for simplifying decision making relative to the occurrence of temporomandibular disorder.

Abstract This study aimed to analyze the videos available on YouTube related to dentistry and the novel coronavirus (COVID-19), as there is no such analysis in the existing literature. The terms “dental” and “COVID-19” were searched on YouTube on May 9, 2020. The top 116 English-language videos with at least 300 views were analyzed by two observers. Data was saved for each video, including target audience, source, country of origin, content, number of views, time watched, average views, duration, like/dislike ratio, and usefulness. Total video information and quality index (VIQI) scores were calculated, consisting of flow, information, accuracy, quality, and precision indices. Non-parametric tests were used for analysis. The analyzed videos were viewed 375,000 times and totaled 20 h of content. Most videos were uploaded by dentists (45.7%), originated from the United States (79.3%), and contained information targeted towards patients (48.3%). Nearly half of the videos (47.4%) were moderately useful. For the usefulness of the videos, statistically significant differences were found for all indices as well as total VIQI scores. A comparison of the indices according to the relevance of the videos showed statistically significant differences in the videos’ information and precision indices and total VIQI scores. The results of this study showed that dentistry YouTube videos related to COVID-19 had high view numbers; however, the videos were generally moderate in quality and usefulness.

RESUMO A intensificação do trabalho do pesquisador e sua submissão a novas formas de avaliação científica caracterizam o atual cenário da pesquisa brasileira. Apesar das múltiplas críticas ao produtivismo (colonialismo epistêmico, geopolítica do conhecimento, mimetismo do publish or perish), são poucas as pesquisas que alcançam o campo empírico a partir do pesquisador como sujeito. Assim, o artigo objetiva analisar os posicionamentos dos pesquisadores brasileiros que mais têm publicado na área de Administração em relação às políticas de avaliação científica adotadas pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), as estratégias de produção adotadas e os principais desafios enfrentados. Para realizar a análise, as vozes foram lidas enquanto enunciados, conforme entendido pela Filosofia da Linguagem Bakhtiniana (FLB), e analisadas com base na Epistemologia Crítica do Concreto (ECC), que possibilita considerar suas contradições. Assim, cada um dos enunciados foi contraposto ao que é simultaneamente silenciado/não dito, mas que apresenta relação direta com o que é afirmado, compondo, portanto, uma unidade dialética, conforme a ECC e a FLB propõem. Os resultados demonstram que os docentes têm priorizado estratégias individuais e por vezes não ponderam o sentido da pesquisa para além das métricas avaliativas, que se constituem em seus sistemas de referência. Por fim, conhecer como os pesquisadores reagem à avaliação mostrou-se fundamental para questionar o atual modelo de avaliação científica, que impacta diretamente tanto na saúde docente quanto na produção científica do país.
