A Comparative Study of Bupivacaine 0.5 % and Ropivacaine 0.75 % for Supra-Clavicular Brachial Plexus Block Using Nerve Locator for Elective Upper Limb Orthopaedic Surgeries
Authors: Singam Amol , Sirige Punith M.
Published: June 2021

BACKGROUND Regional anaesthesia has multiple advantages as compared to general anaesthesia for upper limb surgeries. Here in this study, we wanted to compare bupivacaine 0.5 %, commonly used anaesthetic with ropivacaine 0.75 % which has fewer side effects like cardiotoxicity for supraclavicular brachial plexus block. METHODS A study was performed on 60 ASA I & II patients aged between 18 and 75 years, undergoing upper limb elective surgeries under brachial plexus block using nerve locator. Beginning of sensory and motor block, general nature of block, and terms of sensory and motor blocks were assessed in the C5 to T1 dermatomes. RESULTS There was no statistically significant difference in the onset of sensory and motor blockade between ropivacaine 0.75 % and bupivacaine 0.5 %. Ropivacaine 0.75 % produced similar quality of motor and sensory blockade compared to 0.5 % bupivacaine. The time taken for maximum motor blockade with ropivacaine was comparable with that of bupivacaine 0.5 %. There was no statistically significant difference regarding the duration of analgesia with ropivacaine 0.75 % compared to bupivacaine 0.5 %. Duration of motor blockade with 0.75 % ropivacaine was comparable to that of 0.5 % bupivacaine. CONCLUSIONS Ropivacaine 0.75 % 0.4 ml / kg or 0.5 % bupivacaine 0.4 ml / kg for supraclavicular brachial plexus block produces satisfactory and comparable sensory and motor blockade. It is suggested that lower cardiovascular toxicity of ropivacaine with equal efficacy as bupivacaine in such circumstances may help in reducing the risks to the patient.

Published: June 2021

Purpose: The aim of this study was to assess the incidence and causes of percutaneous radiofrequency ablation (RFA) infeasibility in cases of metastatic colorectal cancer and to evaluate factors affecting the invisibility of the tumor on planning ultrasonography (US).Methods: This study screened 386 patients who underwent planning US using fusion imaging and/or contrast-enhanced US for percutaneous RFA for suspected metastatic colorectal cancer between January 2013 and December 2020, from whom 136 patients with a single hepatic metastasis from colorectal cancer measuring <3 cm were included. The factors related to the infeasibility of percutaneous RFA were investigated. Univariate and multivariate analyses were performed to assess the factors associated with tumor invisibility on planning US.Results: Among the 136 patients, percutaneous RFA was considered infeasible in 24.3% (33/136) due to a high risk of the heat-sink effect caused by the abutment of a large vessel (n=12), an inconspicuous tumor on planning US (n=11), a high risk of collateral thermal damage to an adjacent organ (n=8), and the absence of a safe electrode path (n=2). In univariate and multivariate analyses, tumor size was a statistically significant factor affecting invisibility on planning US (P=0.003 and P=0.018, respectively).Conclusion: Percutaneous RFA was infeasible in approximately one-fourth of patients with metastatic colorectal cancer. The reason for the infeasibility was mainly an unfavorable tumor location and invisibility on planning US. Small tumor size was the sole significant factor affecting the invisibility of hepatic metastases on planning US.

Centrado en los estudios del currículo dentro del campo de producción de conocimiento en Educación Superior (ES), este trabajo se propone analizar e interpretar factores y procesos que operan en los cambios curriculares del nivel universitario. Partimos de concebir al currículo críticamente, como un resultado de luchas y disputas de poder donde algunos actores ganan terreno y otros lo pierden, y nos enmarcamos en la perspectiva organizacional de la ES para indagar en los elementos institucionales y disciplinares que tejen la trama de estos procesos. Nos focalizamos en el estudio del caso de las formaciones de grado en Biología y Física en el Uruguay entre 1985 y 1995. A lo largo de la década indagada tuvieron lugar dos cambios curriculares en las disciplinas analizadas, anclados en dos Facultades distintas de la Universidad de la República. En el entramado del escenario regional, nacional y local, el efecto conjunto de la arena institucional y el devenir de las disciplinas en cuestión le otorgaron a esos procesos de cambio características particulares. Se fueron dando así cambios incrementales, que consolidaron en el poder a ciertos sectores, portadores de una visión particular de la formación en estas áreas del conocimiento.

On a nonlinear relation for computing the overpartition function

Published: June 2021

In 1939, H. S. Zuckerman provided a Hardy-Ramanujan-Rademacher-type convergent series that can be used to compute an isolated value of the overpartition function
p
(n). Computing
p
(n) by this method requires arithmetic with very high-precision approximate real numbers and it is complicated. In this paper, we provide a formula to compute the values of
p
(n) that requires only the values of
p
(k) with k ≤ n/2. This formula is combined with a known linear homogeneous recurrence relation for the overpartition function
p
(n) to obtain a simple and fast computation of the value of
p
(n). This new method uses only (large) integer arithmetic and it is simpler to program.

Gdovin, JR, Galloway, R, Tomasiello, LS, Seabolt, M, and Booker, R. External training load monitoring and the impact on training load management in collegiate male soccer players. J Strength Cond Res XX(X): 000–000, 2023—Soccer is a physically demanding sport within the National Collegiate Athletic Association and continuously increases in popularity. To ensure athletes are adequately prepared for weekly physical stressors, coaches can use global positioning system technology to monitor external workloads and exercise intensity. These data can subsequently help coaches and practitioners better implement individualized training programs to ensure athletes are properly balancing the overreaching and overtraining paradigm. Therefore, the purpose of this observational study was to retrospectively analyze 3 consecutive seasons of external workload (total and high intensity distance) and injury data, which were derived from all training sessions and matches in 46 Division-I collegiate male soccer players. A coach's interpretation sought to provide practical insight into the functionality behind load management and how it prepares athletes for the physical stressors placed on them throughout a season. Two separate 3 × 3 repeated measures ANOVAs were conducted to determine differences between total distance and distance at high-intensity with an alpha level set at 0.05. Total distance between preseason and in-season (p = 0.003), acute high-intensity distance (p < 0.001), and chronic high-intensity distance (p < 0.001) yielded significant differences. These results conclude the demands of each athlete change weekly and between seasons. It is recommended that sport coaches and practitioners develop individualized training programs by workload monitoring while considering variables such as a team's style of play, experience, position, role within a program, training intensity, and the length of time between conditioning sessions, practices, and matches.
Rescuing Auditory Temporal Processing with a Novel Augmented Acoustic Environment in an Animal Model of Congenital Hearing Loss
Authors: Dziorny Adam C. , Luebke Anne E. , Scott Luisa L. , Walton Joseph P.
Published: June 2021

Congenital sensorineural hearing loss (SNHL) affects thousands of infants each year and results in significant delays in speech and language development. Previous studies have shown that early exposure to a simple augmented acoustic environment (AAE) can limit the effects of progressive SNHL on hearing sensitivity. However, SNHL is also accompanied by hearing loss that is not assessed on standard audiological examinations, such as reduced temporal processing acuity. To assess whether sound therapy may improve these deficits, a mouse model of congenital SNHL was exposed to simple or temporally complex AAE. The DBA/2J mouse strain develops rapid, base to apex, progressive SNHL beginning at birth and is functionally deaf by six months of age. Hearing sensitivity and auditory brainstem function was measured using otoacoustic emissions, auditory brainstem response (ABR) and extracellular recording from the inferior colliculus (IC) in mice following exposure to 30 d of continuous AAE. Peripheral function and sound sensitivity in auditory midbrain neurons improved following exposure to both types of AAE. However, exposure to a novel, temporally complex AAE more strongly improved a measure of temporal processing acuity, neural gap-in-noise detection in the auditory midbrain. These experiments suggest that targeted sound therapy may be harnessed to improve hearing outcomes for children suffering from congenital SNHL.
Advocating for The Sustainability of Semai Indigenous Music Through The Collaborative Creation of New Traditional Music: A Participatory Action Research (PAR) Methodology
Authors: Chan Clare Suet Ching , Saidon Zaharul Lailiddin
Published: June 2021

This article provides a critical reflection on the participatory approach methodology and the collaborative creation approach used in an advocacy project to sustain the musical heritage of the indigenous Semai community in Malaysia. These approaches were examined through the medium of an advocacy project that aimed to stimulate the interest of Semai youth in traditional music through relevance, engagement, and connection with their current musical interest and skills. The intention of the project was to also co-create new traditional music with the Semai youth through live musical interaction, improvisation and jam sessions with the research team. This article explored the research team’s use of the “Participatory Action Research” (PAR) method, which involved planning, action, observation, reflection, and revision during the initial stages of our advocacy project. Our findings suggest a narrative style in discussing advocacy processes because they occur in a lateral than the linear or cyclical format used in current action research models. Findings also reveal that any attempts to advocate change in the community would firstly require an established relationship of trust, respect, and belief in the research team. The research team would have to have had prior involvement, commitment, and dedication to the community before members of the team could influence change among the community. A self-review of the research team’s effort to co-create new traditional music with Semai youth led to the conclusion that co-creation between musicians of different musical training would require a “new” compositional method that negotiates Western musical composition techniques with the oral tradition of creating music.

The Physical Health of Caregivers of Children With Life-Limiting Conditions: A Systematic Review
Authors: Hartley Julie , Bluebond-Langner Myra , Candy Bridget , Downie Jonathan , Henderson Ellen M
Published: June 2021

CONTEXT

Parental caregiving for a child with a life-limiting condition (LLC) is complex physical and mental work. The impact of this caregiving on parents’ physical health is unknown.

OBJECTIVES

(1) To review existing evidence on the physical health of parents caring for a child with a LLC and (2) to determine how physical health of parents is measured.

DATA SOURCES

Medline, Embase, PsycINFO, and Cumulative Index of Nursing and Allied Health Literature were searched.

STUDY SELECTION

Peer-reviewed articles were included if they reported primary data on the physical health of a caregiver of a child with a LLC. Studies were excluded if they described only the caregiver’s mental health or if the caregivers were bereaved at the time of data collection.

DATA EXTRACTION

Of 69 335 unique citations, 81 studies were included in the review.

RESULTS

Caregiver health was negatively impacted in 84% of studies. Pain and sleep disturbance were the most common problems. Ways of measuring the physical health of caregiver varied widely. We found an absence of in-depth explorations of the social and economic contexts, which could potentially mitigate the impact of caregiving. Furthermore, we find health interventions tailored to this group remain largely unexplored.

LIMITATIONS

Studies were heterogenous in methodology, making comparisons of results across studies difficult.

CONCLUSIONS

These findings support the need for improving access to interventions aimed at improving physical health in this population. The rate of health-seeking behaviors, preventive health care access and screening for health conditions is understudied and represent important directions for further research.
Transition to a Safe Home Sleep Environment for the NICU Patient
Authors: Goodstein Michael H. , Stewart Dan L. , Keels Erin L. , Moon Rachel Y.
Published: June 2021

Of the nearly 3.8 million infants born in the United States in 2018, 8.3% had low birth weight (ie, weight <2500 g) and 10% were born preterm (ie, gestational age of <37 weeks). Ten to fifteen percent of infants (approximately 500 000 annually), including low birth weight and preterm infants and others with congenital anomalies, perinatally acquired infections, and other diseases, require admission to a NICU. Every year, approximately 3600 infants in the United States die of sudden unexpected infant death (SUID), including sudden infant death syndrome (SIDS), unknown and undetermined causes, and accidental suffocation and strangulation in an unsafe sleep environment. Preterm and low birth weight infants are 2 to 3 times more likely than healthy term infants to die suddenly and unexpectedly. Thus, it is important that health care professionals prepare families to maintain their infant in a safe home sleep environment as per recommendations of the American Academy of Pediatrics. Medical needs of the NICU infant often require practices such as nonsupine positioning, which should be transitioned as soon as medically possible and well before hospital discharge to sleep practices that are safe and appropriate for the home environment. This clinical report outlines the establishment of appropriate NICU protocols for the timely transition of these infants to a safe home sleep environment. The rationale for these recommendations is discussed in the accompanying technical report “Transition to a Safe Home Sleep Environment for the NICU Patient,” included in this issue of Pediatrics.

Published: June 2021

A pandemia da COVID-19, doença grave causada pelo SARS-CoV-2, afeta as pessoas de forma indistinta, porém, devido a sua origem (China), há relatos de xenofobia contra asiáticos, particularmente chineses. Desta forma, este artigo objetiva descrever a xenofobia contra chineses e outros grupos devido à pandemia da COVID-19. Realizou-se uma revisão de literatura de artigos publicados entre janeiro e junho de 2020, por meio de pesquisa nas bases de dados Pubmed, ScienceDirect e SciELO. Os termos utilizados para a seleção foram “coronavirus”, “xenophobia” e “prejudice”. Verificou-se intensa cobertura da COVID-19 nas mídias associada a conteúdos depreciativos ou preconceituosos contra chineses. Também, há uma série de incidentes racistas contra povos da Ásia Oriental na Anglosfera, onde existem grandes grupos minoritários asiáticos, que afetaram indivíduos como estudantes e profissionais, mesmo os da área de saúde, que têm atuado no combate ao SARS-CoV-2. Outros relatos de xenofobia foram reportados na Colômbia, em Bangladesh e na Índia. Concluiu-se que há uma onda de xenofobia relacionada à COVID-19, em especial a chineses, associada à desinformação sobre esta doença e o SARS-CoV-2. As manifestações raciais e os crimes de ódio contra grupos minoritários asiáticos devem ser uma pauta na agenda de combate a esta pandemia.

The present study of mint variety-CIM-Karnti demonstrated for cultivation of Madhepura district of Bihar. Mint is an essential oil bearing plant. Oil and its derivatives are extensively used in food, pharmaceutical, perfumery and flavouring industry. During the study period, 55 farmers of mint cultivation have been demonstrated on the farmer’s field of five villages under Madhepura district of Bihar during 2018-19. The primary data were collected from the selected farmer’s field. Simple analytical tools and technique has been used for data analysis and for carried out the cost of cultivation according different cost concepts. The multiple linear production function was used to evaluate the resource use efficiency in the production of mint. It was observed that medium level adoption of mint cultivation has been found higher followed by high and low level adoption. The total cost of cultivation and gross return has been found Rs. 52,804 /- and Rs. 1, 59,268/- ha-1, respectively. The net return on cost A1, C, Rs. 1,06,464/- and Rs. 90,640/-ha-1. The benefit cost ratio has been observed 2.02 and 1.32 at cost A1 and Cost C, respectively. The independent variables like sucker and nursery raising, manures and fertilizers and distillation charges were positive indicating significant impact on the returns from mint crop in the study area. Thus, profitable returns through cultivation of mint may attract large number of farmers to cultivate this crop to enhance their income and employment in the study area with integrated farming traditional crops.

Published: June 2021

National Agriculture Market (NAM) is an electronic trading portal which networks the existing APMC markets to create a unified national market for agricultural commodities. In Tamil Nadu, about 278 regulated markets are functioning under 21 market committees. Of these eighty regulated markets have been brought under the e-NAM system in two phases during 2017-2020. At present most of the markets are connected with e- NAM portal. The present study was conducted in Dindigul, Annur, Gobichettipalayam, Anaimalai and Tiruppur regulated markets. The major objectives of the study are : to review the progress in implementation of e-NAM in selected regulated markets of Tamil Nadu, to assess the level of awareness about e-NAM among farmers and traders, to study the willingness to participate in e-NAM trading by farmers and traders and to study the benefits and constraints perceived by farmers traders and market officials in adoption of e-NAM. Primary data was collected from 60 farmers and 30 traders in Gobichettipalayam and Anaimalai regulated markets. Binary Logit regression model was used to know the willingness to participate in e-NAM marketing by farmers and traders. Analysis of results shows that the about 30 per cent registered farmers are unaware of e-NAM. And majority of them are not aware of the e-NAM process completely. The major factor influencing the participation of farmers in e-NAM is remunerative price. The major factors influencing the traders participation is influenced by the level of IT knowledge. Constraints faced by farmers in the study markets is delayed payment (95%) followed by inadequate infrastructural facilities. Farmers lack computer skills and faces difficulty in understanding e-NAM process.

In this article various statistical models were fitted utilizing simulated symmetric and asymmetric data. Fitting of models were carried out with the help of various libraries like minpack.lm, matrices and nlme in R studio (version 3.5.1, 2018) and various selection criteria like RMSE, MAE, AIC, BIC were used for fitting of models. In order to evaluate different validation techniques the simulated data was divided in training and testing data sets and various functions in R were developed for the purpose of validation. Co-efficient summary revealed that all statistical models were statistically significant across both symmetric as well as asymmetric distributions. In preliminary analysis TFEM (Type First Exponential Model) was found out to be the best linear model across the distributions with lower values of RMSE, MAE, BIAS, AIC and BIC. Among non-linear models, Haung model was found out to be best model across both the distributions as it has lower values of RMSE, MAE etc. Different validation techniques like Half splitting, LOOCV and 5-folded cross validation were used in the present study. Based on the results of evaluation 5-folded cross validation performed better, as it resulted in lower rates of prediction error in comparison to its counter parts.

Published: June 2021

ABSTRACT Background: Neuropsychiatric symptoms are disorders frequently seen in Alzheimer's disease. These symptoms contribute to reduction of brain reserve capacity and, in addition, they present unfavorable implications, such as: poor prognosis for the disease, increased functional decline, increased burden on the caregiver and institutionalization. This scenario makes neuropsychiatric symptoms one of the biggest problems in Alzheimer's disease, and gives rise to a need for treatments focused on improving these symptoms. Sow progress in drug trials has led to interest in exploring non-pharmacological measures for improving the neuropsychiatric symptoms of Alzheimer's disease, such as physical exercise. Objective: To ascertain the effect of exercise on the neuropsychiatric symptoms of Alzheimer's disease and its implications. Methods: This was a systematic review of effective longitudinal research, conducted by searching for articles in the PubMed, Web of Science, CINAHL and Scopus electronic databases, from 2009 to 2019. Studies in which the sample consisted of elderly people aged 65 years old or over with a diagnosis of Alzheimer's disease were included. Initially 334 articles were identified. After exclusions, 21 articles remained to be read in full. From these, five articles fitted the eligibility criteria, and a further two articles were added through manual searches in the references of the articles found. Results: Out of the seven articles analyzed in this review, five studies revealed that physical exercise had a positive effect on the neuropsychiatric symptoms of Alzheimer's disease. Conclusion: This systematic review indicated that physical exercise is a favorable non-pharmacological means for attenuating the neuropsychiatric symptoms of elderly people with Alzheimer's disease, with special attention to aerobic exercises.

ABSTRACT: Pancreatic cysts are rare in both humans and animals. They are defined as an enclosed structure externally surrounded by a capsule, internally coated with a cuboidal epithelium and filled with liquid or semi-solid content. This case described the clinical and pathological characteristics of a pancreatic cyst in a feline. A mixed breed cat with a history of recurrent vomiting was attended. Physical examination revealed pain on abdominal palpation. Abdominal ultrasonography showed a cystic, anechoic structure with well-defined edges located in the left cranial abdomen and in close contact with the duodenum and pancreas. Partial pancreatectomy was performed. Microscopically, the structure was surrounded by fibrous material, coated with cuboidal to columnar epithelium, and containing eosinophilic material. Although, pancreatic cyst is rare in animals, they should be included in the differential diagnosis of causes of vomiting in young cats.

Published: June 2021

ABSTRACT: This study quantified the chilling requirements for the induction and overcoming of endodormancy (chilling-controlled physiological dormancy) of grapevines buds. Cuttings of the cultivars Chardonnay, Merlot and Cabernet Sauvignon were collected in vineyards in Veranópolis-RS in the winter period of 2019 and 2020. The cuttings were kept at a constant temperature of 7.2 °C or daily cycles of 7.2/18 °C for 6/18 h, 12/12 h or 18/6 h, up to 600 chilling hours (CH). Every 50 CH, part of the cuttings from each treatment was transferred to a temperature of 25 °C for daily assessment of the budburst in the green tip stage. The cultivars had different chilling requirements for inducing and overcoming endodormancy, reaching a total of 150 CH for ‘Chardonnay’, 300 CH for ‘Merlot’ and 400 CH for ‘Cabernet Sauvignon’. Of these, 50 CH were required to induce endodormancy in cultivars Chardonnay and Merlot and 100 CH for cultivar Cabernet Sauvignon. Dormancy evolution did not differ between cultivars in response to thermal regimes, with a temperature of 18 °C inert to the accumulation of CH. Precocity and uniformity of budburst were higher after chilling requirements were met during endodormancy for each genotype.

Published: June 2021

ABSTRACT: Brazil is the largest exporter and second largest producer of soybean grains. Most of this production is from plants grown under no-tillage system (NT). This research evaluated the effect of soil compaction, and different amounts of black oat residues on the soil surface on soybean growth and grain yield in lowland under NT. The experiment was conducted in a completely randomized design with seven treatments and four replications, in the 2016/2017 and 2017/2018 crop seasons. The treatments consisted of: 1) winter fallow without soil compaction (WF); 2) winter fallow with soil compaction (WF-C); 3) black oats and complete removal of surface residues, with soil compaction (0R-C); 4) black oats and removal half of surface residues, with soil compaction (0.5R-C); 5) black oats without surface residue removal, with soil compaction (1R-C); 6) black oats without surface residue removal, plus the residues from treatment 3, with soil compaction (2R-C); 7) black oats without surface residue removal, without soil compaction (1R). When the soybean plants were at the phenological stage R2, they were evaluated nodule, root and shoot dry matter, nitrogen contents, plant height, and grain yield. The soil physical properties were evaluated in the 0.0-0.05, 0.10-0.15 and 0.20-0.25 m layers. The soybean aerial dry matter is > 38% in non-compacted soil in year with soil water excess, regardless of the amount of surface oat straw. In year with small water deficit, soil with more surface oat straw produced > 5% shoot dry matter and > 4% of soybean grain, regardless of compaction. The plant growth and grain yield soybean in lowland varied according to the water conditions, and were affected by soil compaction and amounts of black oats residues on soil surface.

ABSTRACT: Buffalo milk is rich in nutrients and can serve as a substrate for the proliferation of microorganisms. Thus, the objective of the present study was to evaluate the growth kinetics of Salmonella Typhimurium and Listeria monocytogenes in buffalo milk under different processing and storage conditions. Samples of raw and pasteurized milk were inoculated with 1 CFU of each bacterium, separately and together, per 25 mL. After contamination, samples were stored at 8 °C or 37 °C, and bacterial counts were performed at 24, 48, and 168 h. In addition, the accompanying microbiota growth, pH, and the effect of these variables on the growth kinetics of microorganisms were monitored. The pathogens tested were able to proliferate under most conditions tested, reaching high titers throughout the experimental period. At 37 °C, there was a decrease in pH and an increase in the accompanying microbiota that interfered with the microbial growth curve. It was also observed that pasteurized milk subjected to 8 °C provided better conditions for the multiplication of bacteria. Therefore, it was concluded that care throughout the production chain, storage, and commercialization of milk must be adopted to guarantee the microbiological safety of this food.

Abstract Mosquito-borne diseases result in the loss of life and economy, primarily in subtropical and tropical countries, and the emerging resistance to insecticides is increasing this threat. Botanical insecticides are promising substitutes for synthetic insecticides. This study evaluated the larvicidal and growth index of Culex pipiens of four solvent extracts of Terminalia chebula, Aloe perryi, and Peganum harmala against Cx. pipiens. None of the 12 extracts exhibited larvicidal potential against third instars except the ethyl acetate extract of P. harmala. After 24 h of exposure, the LC50 value was 314.88 ppm, and the LC90 value was 464.19 ppm. At 320 ppm, the hatchability was 25.83%, and it resulted in 100% mortality. In addition, the eggs treated with the EtOAc extract of P. Harmala exhibited a long larval period compared with the control. The larval period continued for 12 days, and the pupal period took three days in the treatment groups. The growth index data also exhibited a decrease (0.00–7.53) in the treated groups compare with 8.5 in the control. The transformation of eggs into adults decreased with increasing concentrations. This paper is the first report on the development and growth index of Cx. pipiens potential using P. harmala seeds.

Abstract Tiliroside is a glycosidic flavonoid present in many plants species including Helicteres velutina K. Schum (Malvaceae sensu lato), commonly known in Brazil as “pitó”. This molecule has been shown to have many biological activities, however no study has been carried out to investigate the toxicity of this substance. The present work aimed to evaluate the possible cellular toxicity in silico, in vitro and ex-vivo of the kaempferol-3-O-β-D-(6”-E-p-coumaroyl) glucopyranoside (tiliroside), through chemical structure analysis, toxicity assessment and predictive bioactive properties, using human samples for in vitro and ex-vivo tests. The in silico analysis suggests that tiliroside exhibited great absorption index when penetrating biological membranes. In addition, it also displayed considerable potential for cellular protection against free radicals, and anticarcinogenic, antioxidant, antineoplastic, anti-inflammatory, anti-hemorrhagic and antithrombotic activities. The assessment of the hemolytic and genotoxic effects of tiliroside showed low hemolysis rates in red blood cells and absence of cellular toxicity in the oral mucosa cells. The data obtained indicate that this molecule could be a promising therapeutic approach as a possible new drug with biotechnological potential.

ABSTRACT The outcome of total hip arthroplasty (THA) in dogs is directly related to surgical planning. Templating of radiographs prior to THA should help the surgeon anticipate prosthesis size and femoral shape allowing canal fill of the proximal metaphysis by the implant ensuring primary stable fixation. The canal flare index (CFI) obtained from radiograph has been used as a measure of risk of complications for the technique in human beings and dogs. However, standard radiographs only provide limited data for the selection of cementless prostheses and the assessment of their fit within the femoral canal, due to factors like radiographic magnification and femoral rotation. Therefore, three-dimensional evaluation based on computed tomography (CT) may be a better tool for CFI measurement. The aim of this study was to compare anatomical measurement with CFI values obtained from craniocaudal radiography and CT. Craniocaudal radiographs using a horizontal radiographic beam (CR), CT, and anatomical macroscopic measurements (A) were obtained from 45 femurs from 23 canine cadavers. The differences between the values of CFI obtained from radiograph (CFI-R), computed tomography on transverse (CFI- TT) and longitudinal axis (CFI-TL) compared to the CFI obtained from macroscopic measurements - gold standard - (CFI-A), and 95% limits of agreement (LOA) between the values, were evaluated by the Bland-Altman method. Dimensions obtained from CT techniques had a greatest mean difference from anatomical and CFI values were also different (P=0.032). Under the experimental conditions, the craniocaudal radiograph, provided the most accurate measurement of the CFI (mean difference: 0.087 ± 0.42).

ABSTRACT This study aimed to evaluate the productive performance, dry matter intake, apparent digestibility and ingestive behavior of feedlot calves fed corn silage from the feed out face of trench silos with different types of sealing. The animals were divided into three treatments with four repetitions: Conventional seal - double-sided polyethylene of 110µm thickness; Double-sided seal - double-sided polyethylene of 200µm thickness; and Double seal - composed of double face polyethylene with a thickness of 80µm superimposed on a polyamide translucent vacuum film with a thickness of 20µm. The use of double face sealing provided 12.63% increase in average daily gain and improved food conversion by 0.62 percentage points. The apparent digestibility of the diet with double-face sealing system silage was 4.30% higher than the diet with double-face sealing silage and 11.00% higher than the diet with conventional sealing silage. It is recommended to use the double face sealing with 200µm polyethylene and double face sealing with 80µm thick polyethylene on top of a 20µm thick polyamide translucent vacuum film.
Investigando a compreensão conceitual em física de alunos do ensino médio e o surgimento da “lacuna de gênero”
Authors: Detoni Hugo dos Reis
Published: June 2021

O desempenho em Física dos estudantes das séries iniciais do ensino médio foi medido utilizando um teste conceitual internacionalmente validado. Este estudo envolveu 248 alunos do campus Duque de Caxias do Instituto Federal do Rio de Janeiro durante o primeiro semestre letivo de 2020. Dentre seus principais resultados está o perfil de conhecimento conceitual destes estudantes – lacuna ainda percebida na literatura nacional – por meio da comparação com estudos presentes na literatura nacional e internacional. Os alunos tiveram seu desempenho avaliado em função do gênero e do período no qual se encontram matriculados. Os dados revelam que o ensino de física neste instituto tem surtido pouco ou nenhum efeito, apontando a necessidade de reformulação das metodologias empregadas. Quanto à lacuna no desempenho entre meninos e meninas, comumente apontada em pesquisas envolvendo estudantes universitários, é possível detectá-la quando se consideram todos os indivíduos do espaço amostral, apontando para a necessidade de se considerar o papel da escola secundária no agravamento deste problema. Contribui ainda para a compreensão do processo responsável pela exclusão das meninas do estudo e das carreiras ligadas à Física, cujas consequências são rotineiramente denunciadas por pesquisas que apontam a carência de pesquisadoras envolvidas com as “ciências duras”.
Age and growth of Pseudoplatystoma corruscans (Siluriformes: Pimelodidae) at the confluence of the Paraná and Paraguay rivers

Abstract The age and growth of Pseudoplatystoma corruscans, is analyzed on specimens landed in Puerto Antequera, Province of Chaco, Argentina. The study is based on length frequency distribution of 1192 individuals and growth marks of 293 pectoral spines. Previously to age assignation based on spines readings, we performed analyses that ruled out age-associated resorption of rings and corroborated the annual periodicity of mark formation. The average sizes of the radius of each ring were obtained, and the total length of fish were back-calculated to the time of the ring formation, by the regression model fitted between the total radius of the spines to the respective sizes of each fish. Such data showed a good fitting to growth models of von Bertalanffy, Gompertz and logistic for both sexes separately. Results indicate that the study of the species growth must be carried out for each sex separately and that the fishing regulations must consider this characteristic of the species since the current management guidelines could be promoting differential capture by sexes.
The distribution of Cteniloricaria (Siluriformes: Loricariidae): known and new records in Brazil suggest headwater captures as drivers of disjoint distribution

Published: June 2021

Abstract Cteniloricaria is a genus of Neotropical armored catfishes belonging to the Loricariinae, currently including two valid species: C. platystoma and C. napova. Cteniloricaria platystoma is presently recorded across the main coastal drainages of the Guiana Shield, from the Sinnamary River, French Guiana, to the Essequibo River basin, Guyana, and is considered to be restricted to the region. Cteniloricaria napova is only known from its type locality at the headwaters of the Paru de Oeste River, Amazon basin, Sipaliwini Savannah, Trio Amerindian territory in Suriname, close to the Brazilian border. Based on a specimen of C. napova, captured in the Cuminapanema River, a tributary to the Curuá River, within Brazilian territory, the geographic distribution of the species and the genus is extended, representing the first record of Cteniloricaria in Brazil. The genus shows a disjoint distribution, and divergence between populations in the north-flowing coastal rivers of the Guianas and the south-flowing Amazon tributaries, and more recent headwater capture between south-flowing Amazon tributaries, may have played a key role in shaping its current distribution. Illustrations, diagnostic characters, morphometrics, description of the habitat where the new specimen was captured, extinction risk assessment, and a discussion of the distribution of the genus are provided.
Georg Fuchs and the Social Function of Theater: notes on the book The revolution of the theater
Authors: Oliveira Beatriz Magno Alves de
Published: June 2021

ABSTRACT The article presents and discusses some of the proposals of German theater thinker Georg Fuchs (1868-1949) contained in his book The revolution of the theater: conclusions about the Munich Artists’ Theater, published in 1909. Some of Fuch’s interlocutors during his process of creating the theater are presented. As a central axis, the discussion identifies in each of Fuchs’ aesthetic proposals his perspective of understanding art based on the role it should play in society. We thus seek to not only to identify Fuchs’ aesthetic proposals, but also to emphasize, in addition to them, his political objectives.
Music and Corporeal Mimesis: creative frictions for the dramaturgy of the musician-actuator
Authors: Souza Eduardo Conegundes
Published: June 2021

ABSTRACT Built as a cartographic report, this article aims to give insight to the practical and conceptual procedures carried out during the research process that culminated in the scenic and musical creation of the show Uji - O Bom da Roda. Based on the cartographic method, we focus on encounters and contaminations produced between the theatrical universe and the roda de samba (samba circle) in its multiple expressive dimensions. Within a territory of creative frictions, Corporeal Mimesis presented itself as a fundamental element of articulation between music, body, scene and dramaturgy.
