Published: April 2021

COVID-19 has proved to cause multi-systemic manifestations in many reported cases across the world. Here, we report a rare presentation of a 20 years old COVID-19 positive male patient with acute kidney injury who developed ophthalmoplegia during the course of the disease. COVID-19 being a relatively new disease, its neurological manifestation is even rarer with limited literature concerning the symptoms. Clinicians should, therefore, have a high suspicion and awareness regarding the many faces of the severe acute respiratory syndrome coronavirus-2(SARS-CoV-2), for early detection and mitigation of the disease, especially during the pandemic.

Published: April 2021

Over the last one-year COVID 19 has affected millions of people around the world. Though initially it was thought to be an infection of respiratory system, but it involves any organ of the body. Its morbidity and mortality are more when it involves patients with preexisting cardiovascular diseases and also when it causes a cardiovascular complication. COVID 19 can produce a number of cardiovascular complications including myocardial infarction, heart failure, myocarditis, arrhythmia, thromboembolism etc. Following recovery from COVID 19 infection evaluation, follow up and management of these cardiovascular conditions, which may be sometimes in subclinical form, is essential. Though there is lack of adequate studies or guidelines, we tried to discuss the different aspects of Post- COVID cardiovascular care depending on the existing evidence and previous guidelines.

Published: April 2021

Ischemia of non-occlusive coronary artery disease (INOCA) not an uncommon phenomenon, exist in our patient population which did not address well. Many of the stable angina and or unstable angina patient, whose coronary angiogram revealed significant coronary stenosis (>70%) are being treated by PCI with drug eluting stent. On the contrary, quite a significant proportion of patient, who are found to have non-significant coronary lesion (<50%) or essentially normal epicardial coronaries. These group of patients with angiographic evidence of non-occlusive CAD, remain undiagnosed of their exact etiology of angina. As a result, recurrence of anginal chest pain leading to repeat hospitalization impaired quality of life and the expenditure. Women are significant number in this category, labelled as syndrome X. Many of the scientific literature, has labeled it as Ischemia of Non obstructive Coronary artery Disease. Notably, Microvascular angina is due to ischemia driven mismatch of demand and supply in the myocardium. Microvascular Dysfunction (MVD) and Coronary vascular spasm or Vasospastic Angina (VSA) are the main pathogenic causes of INOCA. With the advent of Imaging physiology, and its availability in Bangladesh, many of the center can assess INOCA and its severity by FFR, iFR, DFR and transthoracic Doppler study of the coronaries. Therefore, we recommend evaluating INOCA patient by available technical assistance and to address the issue and patients suffering with repeated hospitalization and financial expenditure.

Published: April 2021

A discrepância transversa da maxila é comumente observada em pacientes que procuram tratamento ortodôntico, para uma adequada oclusão. É frequentemente definida como uma mordida cruzada posterior e apinhamento dentário anterior. Várias abordagens estão disponíveis para tratar esta discrepância e alcançar a expansão maxilar, sendo conseguida através de técnicas, cirúrgicas e não cirúrgicas. A necessidade de se utilizar a técnica cirúrgica advém quando o paciente já atingiu a maturidade esquelética, desta forma é possível alcançar a dimensão correta da maxila por meio de aparelhos dento-muco-suportados, dento-suportados e ósseo-suportados. No presente caso, a utilização de um aparelho ósseo-suportado mostra vantagens clínicas significativas sobre as outras técnicas uma vez que não observa-se danos aos tecidos ou elementos dentais e sim efeitos exclusivos aos tecidos ósseos resultando em um aumento significativo do arco maxilar e melhora da oclusão, além de melhora respiratória.

The objective of this work was to evaluate the potential of Urochloa brizantha cv. Marandu and Panicum maximum cv. Mombasa in phytoremediation of soil treated with 2,4-D + picloram herbicide, using Raphanus sativus Crimson Gigante as a bioindicator plant. The experiment was carried out in a greenhouse, in a completely randomized design in two stages. In the first stage the treatments were: cultivation of U. brizantha and P. maximum treated with and without the herbicide dose, with five replications. In the second stage, the treatments consisted of cultivating R. sativus in soil: free of herbicide residue; and soil contaminated with cultivation: prior to U. brizantha; P. maximum; and without previous cultivation of grass, with five replications. The units were treated with the herbicide, individually in pre-emergence, after 15 days the grasses were sown. After 50 days, forages were harvested and segregated in aerial and root parts, analyzing fresh and dry biomass (g) and height (cm). After removing phytoremediation plants, R. sativus was transplanted, evaluating visual phytotoxicity at 5, 10, 15 and 20 days after emergence (DAE) and at 20 DAE, the accumulation of green and dry matter (g), height (cm). The evaluated grasses have phytoremediation characteristics for auxinic herbicides; R. sativus can be used as a bioindicator of the herbicide 2,4-D + picloram; the evaluated period was not enough to fully remove the effects of the herbicide.

Restaurações indiretas em resina composta são comumente usadas em dentes posteriores nas diferentes cavidades, permitindo maior resistência ao desgaste, adaptação marginal, estabelecimento de contatos proximais e maior dureza, uma vez que passam pelo processo de termopolimerização. O objetivo desse estudo é relatar um caso clínico de substituição de restaurações em amálgama por restaurações indiretas em resina composta em cavidades com diferentes profundidades. Paciente, sexo feminino, 34 anos, procurou a clínica odontológica de uma instituição privada, queixando-se de insatisfação estética nas restaurações em amálgama nos dentes 45, 46 e 47. Após exame clínico, devido à extensão das cavidades, foi sugerido a realização de restaurações indiretas em resina composta nos três elementos. Após a remoção do amalgama, com ponta diamantada, avaliou-se as profundidades das cavidades dos dentes. No dente 45, realizou-se tratamento endodôntico e instalação de pino de fibra de vidro. No dente 46 foi realizado um capeamento pulpar indireto e no dente 47 não foi realizado nenhum tratamento de proteção pulpar. Posteriormente, os dentes foram preparados para restaurações indiretas com ponta diamantada #3131, em seguida, foram moldados com silicone de adição, prosseguindo com vazamento do molde com gesso tipo IV. O modelo foi troquelizado pela técnica de duplo vazamento e as restaurações em resina composta foram confeccionadas sobre o modelo. Na sessão seguinte, as restaurações foram cimentadas com cimento resinoso dual autoadesivo. Por fim, foi realizado o ajuste oclusal, seguido do acabamento e polimento. As terapêuticas empregadas foram eficazes para recuperar a forma anatômica e estética dos elementos dentários envolvidos.

Published: April 2021

Há décadas, discussões sobre um currículo comum tem sido foco das políticas públicas brasileiras. A implementação da Base Nacional Comum Curricular (BNCC) configura um processo de homogeneização do ensino e vem ganhando forma não só a nível nacional, mas, também, estadual e municipal. Esse estudo tem como objetivo apresentar alguns aspectos relevantes da construção do Documento Orientador Curricular de Santa Maria (DOC/SM). Tanto o Referencial Curricular Gaúcho (RCG) do estado do Rio Grande do Sul quanto o DOC/SM foram currículos elaborados à luz da BNCC. Visando a análise do processo de construção curricular no município de Santa Maria/RS, realizou-se um estudo de campo, com observação participante nos encontros e audiências de construção do documento. Constatou-se, por meio da observação, um dilema entre a tentativa de democratização na construção de uma política municipal (DOC/SM) e a necessidade de alinhamento das políticas educacionais à BNCC. Sinalizando, de forma interdependente – as amarras e a padronização – da atual política de currículo nacional.

This study characterizes the allelopathic effect in the germination of Allium cepa seeds, and toxic on the species Artemia salina, of aqueous extracts of leaves of Aspidosperma pyrifolium and Combretum leprosum and the constituent phytochemical compositions. For this, Allium cepa seeds were germinated in systems containing aqueous extracts (200, 400 and 800 mg.L-1) and distilled water, to evaluate aspects of germination, mitotic phases, mitotic index and limit value of cytotoxicity. The toxicity of the aqueous extracts was evaluated in Artemia salina. The extracts were evaluated qualitatively and quantitatively when the substances present to define the phytochemical profile. The aqueous extract of A. pyrifolium negatively affects the germination process in the hypocotyl and seedling growth at 800 mg.L-1. The LC50 found for the aqueous extract of A. pyrifolium was 4986 mg.L-1. The effect of C. leprosum extract on germination resulted in an increase in the dry matter of the root at 400 mg.L-1 and in the density of the dry matter of the root at 800 mg.L-1. In addition, it reduces the seedling matter at 200 mg.L-1, corresponding to the trend observed in the mitotic index, in which this concentration presented a sublethal score for the limit value of cytotoxicity. The maximum concentration evaluated was not sufficient to determine an LC50 in A. salina. The phytochemical profiles of both species demonstrated classes of substances with potential pharmacological application. This information is important because these species are commonly used as food for farm animals and for purposes in folk medicine.

In cases of injuries in the oral cavity, the mouthwash comes in contact with the underlying gingival connective tissue and should have its cytotoxicity assessed. However, there is no available evidence if cells of elderly donors react differently during in vitro assessments of mouthwashes. This study aimed to compare the cytotoxicity evaluation of two different mouthwash types when assessed with primary gingival fibroblasts from either young and older donors.  Primary cells were collected from two elderly patients (mean age 66.5 years old) and two young patients (mean age 27.5 years old). The primary cell culture was produced from gingival fragments and exposed for 24h in Perioxidin® and Oral B®. A control group was exposed to unconditioned culture media, representing 100% of cell survival (negative control), and 200mg/mL solution of latex fragments was used as a positive control due to its well-known toxicity. Both products presented similar dose-dependent cytotoxicity. In the toxic range, from 0.035% to 0.00035% for Perioxidin® and 0.06 to 0.0006% for Oral B®. The calculated IC50 values were very similar, with the exception of Oral B® tested with young cells, which presented a slightly higher toxic concentration (0.0523 mM). The statistical analysis shows no significant difference between tests with cells from young our elderly donors (p >0.05). These mouthwashes should should be used sparingly to prevent the spread of SARS-CoV-2. However, the use of age-matched cells during in vitro tests may not be necessary to predict differences in the biological response of the elderly to these products.

The aim of this systematic review was to compare the clinical performance of calcium hydroxide (Ca(OH)2) as an intracanal medicament alone or combined with other antimicrobial agents. The PICO question was “Is the antibacterial effectiveness of calcium hydroxide paste as an intracanal medication combined with other drugs greater than that of calcium hydroxide paste alone in apical periodontitis?” The study was carried out according PRISMA guidelines and is registered in PROSPERO (CRD42020205741). Searches were performed in the PubMed/MEDLINE, Web of Science and Cochrane databases without publication date restrictions. Inclusion: randomized clinical trials, non-randomized intervention studies, studies including a minimum of 10 patients, studies comparing the use of Ca(OH)2 alone and in combination with other compounds,  studies evaluating primary and permanent teeth with apical periodontitis, and studies including teeth not submitted to retreatment. The Cochrane risk-of-bias tool for randomized clinical trials (RoB 2.0) was used to assess the internal validity (risk of bias) of the included studies. A total of 986 articles were retrieved and 12 randomized clinical trials were selected, totaling 499 patients included in the studies. The effectiveness of Ca(OH)2 plus chlorhexidine was similar to that of Ca(OH)2 alone in eight articles, while a better antibacterial effect was reported in three studies. The combination with ciprofloxacin was more effective than the use of Ca(OH)2 alone in the only study that tested this antibiotic. In teeth with asymptomatic apical periodontitis, the effectiveness of the combination of antimicrobial agents with Ca(OH)2 was similar to that of Ca(OH)2 alone.

Published: April 2021

No Brasil, existem diversas regiões endêmicas simultaneamente para leishmaniose e doença de Chagas e como os agentes causadores pertencem ambos à mesma família, Trypanosomatidae, eles compartilham diversos antígenos, que no momento do diagnóstico sorológico, podem promover reações cruzadas. Diversos autores avaliaram a reação cruzada Chagas/leishmaniose em cães, entretanto poucos trabalhos fizeram este questionamento em humanos. O objetivo do presente estudo foi identificar a possibilidade de reação cruzada para o diagnóstico da doença de Chagas em pacientes com leishmaniose visceral curada. Para tanto, foram analisadas 30 amostras de soro de pacientes com leishmaniose visceral curada atendidos no Ambulatório de Infectologia do Hospital Regional de Presidente Prudente, São Paulo. As amostras foram avaliadas em duplicata através de três kits sorológicos para o diagnóstico da doença de Chagas: ensaio imunoenzimático (ELISA), imunofluorescência indireta (IFI) e hemaglutinação indireta (HAI). Das 30 amostras analisadas, apenas o soro de um paciente mostrou-se reagente na IFI, entretanto, a duplicata avaliada não foi positiva, assim como os resultados de ELISA e HAI. No presente estudo, devido à reatividade para a IFI apresentar apenas um T. cruzi marcado, com a sua duplicata e outros testes sorológicos (ELISA e HAI) negativos, podemos concluir que o paciente com leishmaniose visceral apresentou uma reação cruzada para o diagnóstico da Doença de Chagas.

A saúde bucal faz parte da saúde física e mental, pois interfere tanto na mastigação e digestão quanto na possibilidade de comunicação. O objetivo deste estudo foi identificar as condições de saúde bucal de pacientes internados em uma instituição psiquiátrica e discutir implicações para os processos de reabilitação psicossocial. O estudo foi realizado com 104 pacientes, utilizando o odontograma e entrevista semiestruturada individual para a coleta de dados. Os dados quantitativos foram analisados utilizando-se a estatística descritiva e o índice CPO-D, apresentando resultados por frequências absolutas e relativas e medidas de tendência central, os dados qualitativos foram tratados por meio da técnica de análise de conteúdo. Os resultados evidenciaram índice de CPO-D médio de 19,41 para homens e 20,38 para mulheres e perda total de dentes nas mulheres de 29% e nos homens de 6,06%. Da análise do conteúdo emergiu duas categorias: "Ausência total de dentes (edêntulas) interferindo na comunicação" e "Ausência de dentes e a autoimagem/estética". Conclui-se que a relação entre a saúde bucal e estratégias de reabilitação psicossocial precisam ser consideradas no decorrer do processo terapêutico pela equipe multiprofissional.

Published: April 2021

A teca (Tectona grandis L.f.) é uma árvore de origem asiática que vem sendo extensamente implantada no Brasil, porém, seu uso é restrito devido à dificuldade na produção de mudas, sendo a utilização de compostos orgânicos uma alternativa para sua produção. Portanto, objetivou-se avaliar o uso de esterco de caprino, caule decomposto de babaçu e bokashi como componentes de substratos na produção de mudas de teca. O experimento foi conduzido em casa de vegetação com duração de 60 dias. Foi utilizado delineamento inteiramente casualizado, com dez tratamentos, compostos por esterco caprino (EC1, EC2 e EC3), caule descomposto de babaçu (CB1, CB2 e CB3) e bokashi (BO1, BO2 e BO3), com proporções de 45, 30 e 15%, respectivamente, associados ao solo, contendo um tratamento controle com 100% solo (Latossolo Vermelho Amarelo distrófico), e quatro repetições. Foram avaliadas a altura da parte aérea, o diâmetro de colo, o número de folhas e o Índice de Qualidade de Dickson. Os dados foram analisados através do software InfoStat© e as médias comparadas pelo teste Duncan. O uso de bokashi e esterco de caprino como componentes de substratos na produção de mudas de teca possibilita desempenhos favoráveis. A utilização de no mínimo 15% de bokashi ou de esterco caprino permitiram a formação de mudas de melhor qualidade.

A presente pesquisa teve como finalidade analisar a viabilidade da comercialização de mudas e da polpa do açaí no município de Zé Doca, estado do Maranhão. O trabalho foi desenvolvido no município de Zé Doca/MA, local onde são produzidas e comercializadas as mudas de açaí (Euterpe oleracea Mart.). A coleta de dados utilizou como base o uso de questionários semiestruturados, aplicados de forma direta a quatro produtores do município, onde as informações obtidas pela pesquisa foram estruturadas pelo programa Microsoft Excel para produção de gráfico e análise dos dados. Os resultados com os comerciantes do fruto apontam uma significativa e crescente expansão do açaí no mercado local, com valores e análises de dados expressivos que especulam uma tendência desse crescimento econômico. Sua rentabilidade é consideravelmente alta quanto ao retorno econômico do agricultor familiar, a circulação do açaí local tem viés de mercado formal e informal para a geração de renda e sustento de famílias no espaço social, e surgimento crescente de consumo e suas disparidades de retorno econômico para o estado na produção do açaí. A partir da análise conclui-se que tanto a comercialização da muda quanto da polpa do açaí é rentável ao agricultor, tendo em vista que os gastos para a produção são baixos e a demanda para consumo só tende a aumentar trazendo benefícios socioeconômicos a esses produtores, porém faz-se necessário o apoio técnico para os comerciantes afim de orientá-los nas estratégias de comercialização de seus produtos.

Published: April 2021

The present study was conducted to identify and discuss the social norms, perceptions, and expectations which shape or constraint men’s, and women’s economic empowerment. The current study was conducted in the rice cultivation sectors of Sheikhupura and Gujranwala districts of the Punjab Province, Pakistan.  A qualitative (cross-sectional) study was designed to get responses from the respondents of the targeted area. One tehsil was purposively selected from each district and sixty-five respondents (both males and females) were invited from 13 different villages of the above-mentioned tehsils. Focused Group Discussions (FGDs) were held for data collection activity in collaboration with the Doaba Foundation. A pre-defined interview guide based on Oxfam’s Social Norms Diagnostic Toolkit and Rapid Care Analysis Toolkit was used to collect opinions from the respondents with the inclusion of various exercises. The major findings of the study revealed that most of the care work yielded by women ranging from the rice cultivation to the household chores go unacknowledged, because it is included in the total household income, and the rural women face discrimination in every sphere of life. The study concludes that to achieve women’s economic empowerment, adequate wages, and safe working conditions, where they are protected from sexual and gender-based violence, must be ensured. The government should devise policies for the protection of women regarding discrimination and implement it in true spirit to fulfil the dream of the economic empowerment of women in Pakistan.

Published: April 2021

Citrus family consists of a variety of eatable, consumable and usable items with varying nutritional contents. Naked eye citrus classification needs expert human effort, which provides poor decision reliability. The unreliable classification decision may be extremely hazardous when the citrus is being classified for exports or usage in pharmacy products and various food items. In this paper, citrus fruit has been classified on shape and texture features. Principal Component Analysis (PCA) was used as a methodology to explore statistical findings. The average accuracy of the system proposed is 84%. This system can be implemented on pharmacy stores, food production units, or industries, and citrus export centers for reliable citrus fruit classification.

Published: April 2021

On the eve of changing climate, it is expected that there will be a competition to reallocate water for agricultural, industrial and urban needs in near future. Thus, in view of the increased water scarcity, an adequate management for water application is required to maximize water use and increase yield. In this regard, a field trial comprising four deficit drip irrigation treatments on potato crop under drip irrigation was conducted in filed condition using RCB design with four replications. Cropwat 8.0 program was used to determine the interval and depth of next irrigation at 15, 30, 45 & 60% management allowable depletion (MAD) of soil moisture. The outcomes indicated that irrigation to potato crop at 30% MAD level gave the highest water productivity (17.28 kg/m3) followed by 60, 15 and 45% MAD levels. Maximum %age of medium sized tuber was achieved by applying irrigation to potato crop at 60% MAD level (65.70) followed by 30% MAD level (65.5), 45% MAD (64.0) and 15% MAD level (60.50). The incidence of scab was found 2.50%, 2.75%, 3.25% and 3.75% in potato tubers at 15, 30, 45 and 60% MAD level, respectively.

Turizm sektörü içerisinde yer alan otel işletmelerinin önemi gelişmekte olan ülkelerde giderek artmaktadır. Otel işletmeleri, küresel ekonomik kriz sırasında bile gelişmektedir ve istihdam yaratmaktadır. Otel işletmelerinin sayılarının artması ile beraber, istihdamın ve bu alanda rekabetin artması, çalışanların bu sektör içinde karşı karşıya kalacakları risk ve tehlikeleri de arttırmıştır. Bu nedenle iş kazaları ve meslek hastalıkları açısından otel işletmelerini değerlendirmek önemlidir. Bu çalışma, otel işletmelerindeki iş sağlığı ve güvenliğinin durumunu anlamak, iş sağlığı ve güvenliği risklerini belirlemek ve otel işletmelerinde acil durum önlemlerinin ne ölçüde uygulandığını incelemek amacıyla Elazığ’da bulunan dört yıldızlı turistik bir otel işletmesinde yapılmıştır. Çalışmada, Fine-Kinney yöntemi kullanılarak, iş yerinin iş sağlığı ve güvenliğinin risk analizi ve değerlendirmesi yapılmıştır. Risk değerlendirmesi sonucunda otelcilikte toplam 52 risk tespit edilmiş, bu risklerin ortadan kaldırılması yahut kabul edilebilir seviyelere indirgenmesi için bazı önerilerde bulunulmuştur.

Objectives: The aim of this study was to evaluate the effects of oxidative stress on thiol-disulfide homeostasis caused by hypotensive anesthesia in mastoidectomy-tympanoplasty cases undergoing controlled hypotension.
Methods: Fifty adult patients scheduled for mastoidectomy and tympanoplasty were included in the study. Anesthesia was induced with lidocaine, propofol, rocuronium, and remifentanil. The maintenance of anesthesia was continued with remifentanil infusion (target mean arterial pressure as 60-65 mmHg) along with 2% sevoflurane/40% O2/air mixture. Blood samples were taken 5 times at the t0 (before induction), t1 (intraoperatively after intubation), t2 (first hour) and t3 (second hour of the operation) and t4 (following recovery). Total thiol (TT) and Native Thiol (NT) levels were measured, and thus, Di-Sulphide (SS), Di-Sulphide/Native Thiol (SSNT), Di-Sulphide/Total Thiol (SSTT), and Native Thiol/Total Thiol (NTTT) values were estimated.
Results: During the operation, progressive decrease was observed in thiol levels of patients. There was a significant decrease in t3 thiol values when compared with t0 value. Thiol values were observed to have returned to baseline values after recovery from anesthesia (p>0.05). SS, SSNT and SSTT levels were found as increased in t1 blood samples, but increase in SSNT and SSTT levels was significant. Throughout the operation, values were observed to have dropped and reverted back to initial values.
Conclusion: Since the measurement of thiol-disulfide blood values is able to show the instantaneous state of oxidative stress, it can be used in anesthesia practice in which every event occurs very quickly.

Objective: Corona virus disease is a serious acute respiratory infection that has spread worldwide. The aim of this survey study was to evaluate the knowledge levels, attitudes, and approaches of dentists in Turkey and to investigate the infection control measures applied by the dentists in the dental clinics regarding the COVID-19 pandemic.

Methods: This survey consisted of 27 questions and was conducted in May 2020. The questionnaire, which was distributed online to the participants through their personal accounts, included questions about the socio-demographic characteristics of the participants, their knowledge and awareness of COVID-19 infection, their approach to dental procedures before and during the pandemic, and the control measures they took in dental clinics. The collected data were subjected to statistical analysis using Chi-square tests and P values of < 0.05 were accepted as statistically significant.

Results: Eight hundred twenty-eight dentists completed the questionnaire forming a response rate of 51.8%. The majority of the participants demonstrated a high level of knowledge and awareness regarding COVID-19. The statistical analysis showed that there was no association between the gender of dentists and the applied infection control measures (P > 0.05), while there were significant associations between the health sectors and experience years with the infection control measures (P < 0.05).

Conclusion: These results demonstrated an adequate level of knowledge regarding COVID-19 among dentists in Turkey. Additionally, the rate of using personal protective equipment during dental treatment was high.
A Preliminary Investigation of Social Network Analysis Applied to Dairy Cow Behavior in Automatic Milking System Environments

We have applied social network analysis (SNA) to data on voluntary cow movement through a sort gate in an automatic milking system to identify pairs of cows that repeatedly passed through a sort gate in close succession (affinity pairs). The SNA was applied to social groups defined by four pens on a dairy farm, each served by an automatic milking system (AMS). Each pen was equipped with an automatic sorting gate that identified when cows voluntarily moved from the resting area to either milking or feeding areas. The aim of this study was two-fold: to determine if SNA could identify affinity pairs and to determine if milk production was affected when affinity pairs where broken. Cow traffic and milking performance data from a commercial guided-flow AMS dairy farm were used. Average number of milked cows was 214 ± 34, distributed in four AMS over 1 year. The SNA was able to identify clear affinity pairs and showed when these pairings were formed and broken as cows entered and left the social group (pen). The trend in all four pens was toward higher-than-expected milk production during periods of affinity. Moreover, we found that when affinities were broken (separation of cow pairs) the day-to-day variability in milk production was three times higher than for cows in an affinity pair. The results of this exploratory study suggest that SNA could be potentially used as a tool to reduce milk yield variation and better understand the social dynamics of dairy cows supporting management and welfare decisions.

The objective of this study was to evaluate the addition of cane molasses during a 60 day dry period on performance and metabolism of Holstein cows during prepartum and postpartum periods. For experiment 1, 26 primiparous and 28 multiparous cows were used. Upon freshening, all cows were offered a common lactation diet. For experiment 2, six multiparous cows fitted with rumen cannulas were used to measure performance and metabolism, following the same protocol as experiment 1. Ruminal propionate increased by 10% during both prepartum and postpartum periods; however, papillae area was greater for cows not fed molasses, and volatile fatty acids (VFA) absorption from the rumen was not increased, resulting in similar glucagon-like-peptide-2 receptor (GLP-2R) density. The improved dry matter intake, when molasses was added into prepartum diets, translated into increased milk yield and energy-corrected milk (ECM) in Experiment 1 only for multiparous cows. For experiment 2, the improvement on milk performance was also observed, where cows fed molasses had 18.5% greater ECM production. Feeding molasses during a 60 day dry period positively influenced transition cow performance, and it was not accompanied by changes in rumen morphometrics; however, this indicates enhanced adaptation by the rumen epithelium based on similar capabilities for VFA absorption.

The objective of this systematic review was to synthesize all the preclinical studies carried out in periosteal distraction osteogenesis (PDO) in order to evaluate the quality using the ARRIVE guidelines. The animal models used, and the influence of the complications, were analysed in order to establish the most appropriate models for this technique. The PRISMA statements have been followed. Bibliographic sources have been consulted manually by two reviewers. Risk of bias was evaluated using the SYRCLE tool for animal studies, and the quality of the studies with the ARRIVE 2.0 guidelines. The selection criteria established by expert researchers were applied to decide which studies should be included in the review, that resulted in twenty-four studies. Only one achieved the maximum score according to the ARRIVE 2.0 guidelines. The rabbit as an animal model has presented good results in PDO, both for calvaria and jaw. Rats have shown good results for PDO in calvaria. The minipig should not be recommended as an animal model in PDO. Despite the increase in the quality of the studies since the implementation of the ARRIVE 2.0 guidelines, it would be necessary to improve the quality of the studies to facilitate the transparency, comparison, and reproducibility of future works.

Oxidative stress induced by the overproduction of free radicals or reactive oxygen species (ROS) has been considered as a key pathogenic mechanism contributing to the initiation and progression of injury in liver diseases. Consequently, during the last few years antioxidant substances, such as superoxide dismutase (SOD), resveratrol, colchicine, eugenol, and vitamins E and C have received increasing interest as potential therapeutic agents in chronic liver diseases. These substances have demonstrated their efficacy in equilibrating hepatic ROS metabolism and thereby improving liver functionality. However, many of these agents have not successfully passed the scrutiny of clinical trials for the prevention and treatment of various diseases, mainly due to their unspecificity and consequent uncontrolled side effects, since a minimal level of ROS is needed for normal functioning. Recently, cerium oxide nanoparticles (CeO2NPs) have emerged as a new powerful antioxidant agent with therapeutic properties in experimental liver disease. CeO2NPs have been reported to act as a ROS and reactive nitrogen species (RNS) scavenger and to have multi-enzyme mimetic activity, including SOD activity (deprotionation of superoxide anion into oxygen and hydrogen peroxide), catalase activity (conversion of hydrogen peroxide into oxygen and water), and peroxidase activity (reducing hydrogen peroxide into hydroxyl radicals). Consequently, the beneficial effects of CeO2NPs treatment have been reported in many different medical fields other than hepatology, including neurology, ophthalmology, cardiology, and oncology. Unlike other antioxidants, CeO2NPs are only active at pathogenic levels of ROS, being inert and innocuous in healthy cells. In the current article, we review the potential of CeO2NPs in several experimental models of liver disease and their safety as a therapeutic agent in humans as well.
