Wearable near-infrared spectroscopy: reliability and sensitivity among different endurance cycling exercise intensities

The present study investigated the reliability and sensitivity of a wearable near-infrared spectroscopy (wNIRS) device in moderate and heavy exercise intensity domains. On three separate days, eleven males performed an incremental test to exhaustion, and in the following visits, four submaximal constant-load bouts (i.e., test and retest) were performed in the moderate-intensity domain (100 and 130 W) and heavy-intensity domain (160 and 190 W). The local tissue oxygen saturation index (SmO2) and pulmonary oxygen uptake (V̇O2) were measured continuously. The absolute SmO2 and V̇O2 values and the change (Δ) from the 3rd to 6th min of exercise were calculated. There was good reliability for SmO2 measurements, as indicated by the high intraclass correlation coefficient analysis (ICC ≥0.84 for all) and low coefficient of variation between the two trials (CV ≤4.1% for all). Steady-state responses were observed for SmO2 and V̇O2 from the 3rd to the 6th min in the two moderate-intensity bouts (P>0.05), whereas SmO2 decreased and V̇O2 increased from the 3rd to the 6th min in the two heavy-intensity bouts (P<0.05). Together, these findings suggested that the SmO2 measured with a wNIRS device is reliable and sensitive to track local metabolic changes provoked by slight increments in exercise intensity.

Phallus eversion sexing in Phrynops geoffroanus (Testudines: Chelidae): a new non-invasive approach

Abstract The sexing of species is an important tool for population management. In tortoises and turtles, sexing is usually done according to secondary characteristics, such as plastron morphology or phallus eversion techniques. In this paper, we present the phallus eversion method and compare its efficiency to other existing techniques. This new method aims at shortening the management time and reducing the physical aftereffects on the animals, fostering the clinical and reproductive management of Geoffroys side-necked turtle (Phrynops geoffroanus) and related species. A sample of fifty individuals was taken in the central region of Piauí state, Northeastern Brazil. The proposed method consisted of moving the head from its resting position. The methods achieving a success rate higher than 80% were compared to each other as for the stimulation time required for phallus eversion. The method as here proposed achieved 100% efficiency in the sex determination of specimens with a linear carapace length between 10 and 34 cm. Also, when compared to the second most efficient method, it substantially reduced the time needed for managing the specimens (91%), avoiding possible sequelae in the individuals handled.

Resumo A sexagem das espécies é uma ferramenta importante para o manejo populacional. Em tartarugas, cágados e jabutis, a sexagem geralmente é feita de acordo com características secundárias, como morfologia do plastrão ou técnicas de eversão do falo. Neste artigo, apresentamos o método de eversão do falo e comparamos sua eficiência com outras técnicas existentes. Este novo método visa encurtar o tempo de manejo e reduzir os efeitos colaterais físicos nos animais, promovendo o manejo clínico e reprodutivo do cágado-de-barbicha (Phrynops geoffroanus) e espécies relacionadas. Uma amostra de cinquenta indivíduos foi coletada na região central do estado do Piauí, Nordeste do Brasil. O método proposto consiste em remover a cabeça de sua posição de repouso. Os métodos que obtiveram índice de sucesso superior a 80% foram comparados entre si quanto ao tempo de estimulação necessário para a eversão do falo. O método aqui proposto alcançou 100% de eficiência na determinação do sexo de espécimes com comprimento de carapaça linear entre 10 e 34 cm. Além disso, quando comparado ao segundo método mais eficiente, reduziu substancialmente o tempo necessário para o manejo dos espécimes (91%), evitando possíveis sequelas nos indivíduos manuseados.

Characterization of the Bipolaris maydis: symptoms and pathogenicity in popcorn genotypes (Zea mays L.)

Abstract Southern corn leaf blight (SCLB) is one of the most important corn leaf diseases. Appropriate management strategies and the use of resistant cultivars allow disease control. Therefore, knowing the aspects related to the pathogen and the response of hosts makes it possible to design efficient strategies for selecting genotypes resistant to this disease. In this sense, the objective was to carry out the Bipolaris maydis isolate characterization, evaluating the pathogenicity in different popcorn lines and the symptoms generated in the host after inoculation. The isolate characterization consisted of the macromorphological evaluation of the colonies and the micromorphological evaluation of the conidia in the PDA medium. An experiment was carried out in a greenhouse to evaluate the pathogenicity of the isolate, using 20 inbred lines of popcorn in a randomized block design with four replicates. Inoculation was carried out by spraying leaves, with a suspension containing 1.0 x 104 conidia.ml-1 of the CF/UENF 501 isolate of B. maydis. An incidence assessment and three assessments of disease symptom severity were performed, with seven days intervals between evaluations. The morphological characterization data of the isolate were analyzed using descriptive statistics, and for disease severity, the linear regression model was applied the first-degree model. The variance analysis was performed for the linear and angular coefficients obtained for each treatment. When a difference was found, the Scott-Knott clustering algorithm at 5% significance was applied. The isolate had gray-green colonies, a cottony appearance, and an irregular shape. The lines L353, L354, and L624 show more resistance at the beginning and throughout the evaluations. The high virulence of the CF/UENF 501 isolate made it possible to differentiate the lines in terms of disease intensity and the pattern of symptoms presented.

Resumo Mancha-de-Bipolaris é uma das mais importantes doenças foliares do milho. Estratégias de manejo adequadas e o uso de cultivar resistente permitem o controle da doença, mas para tanto, conhecer os aspectos associados ao patógeno e a resposta do hospedeiro é necessário para traçar estratégias eficientes para seleção de genótipos resistentes a essa doença. Neste sentido, objetivou-se realizar a caracterização do isolado de Bipolaris maydis avaliando a patogenicidade em diferentes linhagens de milho-pipoca e os sintomas gerados no hospedeiro a partir da inoculação. A caracterização do isolado consistiu na avaliação macromorfológica das colônias e micromofológica dos conídios em meio nutritivo BDA. Para avaliação da patogenicidade do isolado foi conduzido um experimento em casa de vegetação utilizando 20 linhagens endogâmicas de milho-pipoca, com delineamento em blocos casualizados, com quatro repetições. A inoculação foi realizada por meio de pulverização em folhas, com uma suspensão contendo 1,0 x 104 conídios.ml-1 do isolado CF/UENF 501 de B. maydis. Foi realizada uma avaliação de incidência e três avaliações de severidade dos sintomas da doença, com o intervalo de sete dias para cada avaliação. Os dados da caracterização morfológica do isolado foram analisados por meio da estatística descritiva e para severidade da doença foi aplicado o modelo de regressão linear de primeiro grau. Realizou-se a análise de variância para o coeficiente linear e angular obtido para cada tratamento e quando constatada diferença aplicou-se o agrupamento de médias de Scott-knott a 5% de significância. O isolado apresentou colônias com coloração cinza esverdeado, aspecto algodonoso e forma irregular. As linhagens L353 e L354 e L624 estão entre as linhagens que apresentaram maior resistência no inicio e ao longo das avaliações. A elevada virulência do isolado CF/UENF 501 possibilitou diferenciar as linhagens quanto a intensidade da doença, bem como o padrão dos sintomas apresentados.

The burden of skin diseases in India: Global Burden of Disease Study 2017

Background: The prevalence of skin diseases has increased over the last few decades, and they contribute to a significant burden on health-care systems across the world. Aims/Objective: This report looks at the burden of skin and subcutaneous diseases in terms of years lived with disability and age-standardised years lived with disability in India using the Global Burden of Disease Study results from 2017. Methods: Data were obtained from the Global Burden of Disease online interactive tool. Updated estimates of the world’s health for 359 diseases and injuries and 84 risk factors from 1990 to 2017 are available in this interactive tool. Results: Years lived with disability due to skin and subcutaneous diseases accounted for 4.02% of the total years lived with disability in India in 2017. There was an increase of 53.7% in all age standardised years lived with disability for all the skin and subcutaneous diseases from 1990 to 2017. Among skin and subcutaneous diseases, dermatitis contributed maximum years lived with disability (1.40 million; 95% uncertainty interval, 0.82–2.21) in 2017, followed by urticaria (1.02 million; 95% uncertainty interval, 0.06–1.44) with percentage increases of 48.9% and 45.7% respectively. Conclusion: The burden due to infectious skin diseases (e.g., scabies, fungal skin disease and bacterial skin disease) and non-infectious diseases (e.g., dermatitis, urticaria and psoriasis) has increased over the past three decades, however the age-standardised years lived with disability for leprosy, scabies, fungal infections, sexually transmitted infections and non-melanoma skin cancer (basal cell carcinoma) has decreased. The high burden of skin and subcutaneous diseases demand that they be given due importance in the national programmes and health policy of India.

Reabilitação com prótese bucomaxilofacial: revisão de literatura / Rehabilitation with maxillofacial prosthetics

A odontologia reabilitadora tem como um dos seus ramos a especialidade de Prótese Bucomaxilofacial (PBMF), que visa restaurar ou substituir estruturas perdidas na região facial e no sistema estomatognático artificialmente, podendo ser ou não removidos pelo paciente. O presente trabalho objetiva revisar a leitura a respeito da reabilitação com PBMF e a sua aplicabilidade na clínica odontológica. Os indivíduos com alguma perda de estrutura na região de cabeça e pescoço, devido a traumas físicos e/ou químicos, defeitos congênitos, doenças autoimunes, neoplasias, infecções e parasitas, são pacientes para os quais há a indicação da reposição da parte ausente. As reconstruções podem ser perdas intraorais (área da maxila, mandíbula), extraorais (oculopalpebral, ocular, nasal, facial extensa e auricular) ou conjugadas. Esse é um trabalho multidisciplinar, com especialistas de áreas abrangentes e todos os especialistas trabalham de forma conjunta. Pode-se concluir que, embora seja uma das especialidades mais nobres da odontologia, ainda é muito desconhecida por parte dos estudantes e profissionais das áreas da saúde e são próteses absolutamente fundamentais para a reabilitação e qualidade de vida dos indivíduos que tem a necessidade do uso da prótese PBMF(AU)

Rehabilitating dentistry has as one of its branches the specialty of Oral and Maxillofacial Prosthesis (PBMF), which aims to restore or replace structures lost in the facial region and in the stomatognathic system artificially, which may or may not be removed by the patient. The present study aims to review the reading about rehabilitation with PBMF and its applicability in dental clinic. Individuals with some loss of structure in the head and neck region, due to physical and/or chemical trauma, birth defects, autoimmune diseases, neoplasms, infections and parasites, are patients in whom there is an indication for replacement of the absent part. Reconstructions can be intraoral (maximal area, mandible), extraoral (oculopalpebral, ocular, nasal, extensive facial and auricular) or conjugated losses. It is a multidisciplinary work, with specialists from the comprehensive areas and that all specialists work together. It can be concluded that although it is one of the noblest specialties of dentistry, it is still very unknown to students and health professionals, and they are absolutely fundamental prostheses for the rehabilitation and quality of life of individuals who need the use the PBMFprosthesis(AU)

Isolation of Actinomycetes from Arachis hypogaea L. and Gossypium herbaceum L. for Screening Antibacterial and Antifungal Activities

The principal objective of the present study was to check the antimicrobial activity of Actinomycetes isolated from soil samples collected from the fields of Arachis hypogea L. and Gossipium herbaceum L. against different plant pathogenic strains. Various soil samples were isolated from fields located near the Junagadh district, Gujarat, India. Isolation was followed by a serial dilution process which was later plated on Actinomycete Isolation Agar (AIA) media. Potential colonies were subjected to screening, purification, and storage in glycerol stock. Morphological and Biochemical characterization of the isolates was performed. Isolated candidates were subjected to extraction for the production of the antimicrobial compound. The antimicrobial activity of the purified extract of isolates was tested. Total 30 actinomycete isolates were evaluated for antagonistic activity against pathogenic microorganisms. Isolates C-25, C-15, and G-1 showed the best results in the decreasing order of their potency against fungal pathogens, and C-5, C-25, C-14, and C-13 showed the best results in decreasing order of potency against bacterial pathogens. 3 isolates inhibited all 4 test fungi. 10 isolates inhibited 3 test fungi. 11 isolates inhibited 2 test fungi. 6 isolates did not inhibit any test fungi. 4 isolates show potent inhibition. 15 inhibited Macrophomina. C-10 showed a 1 cm inhibition zone & G-1 showed a 0.8 cm zone of inhibition. 12 isolates gave 0.2-0.6 cm zone and 15 isolates gave negative results against Macrophomina. C-10 showed a very potent zone of inhibition of 0.7 cm. 9 isolates showed a 0.1-0.5 cm zone of inhibition. 20 isolates did not show inhibition against Fusarium. 1 isolate C-11(a) gave the 1cm potent zone of inhibition. 15 isolates gave the 0.7-0.2cm inhibition of the growth. 14 isolates gave negative results against Alternaria fungus. From these results, it was concluded that isolates had antibacterial and antifungal activities and could be used in the development of new antibiotics for pharmaceutical or agricultural purposes.

A Clinical Analysis of Phlebolymphedema and Its Relationship with Physical Activity and Disability

Background: The clinical features and epidemiological data about patients with phebolymphedema or lymphedema related to Chronic Venous Disease in Mexico is limited and has been understudied; at the same time, the relationships between its clinical features, physical activity level and disability remained unknown. Methods: This is a longitudinal cohort study based on the analysis of clinical data of 90 patients gathered between 2021 and 2022. The statistical analysis was carried out using the software SPSS version 25 and GrandhPad Prism 8; a descriptive analysis was developed using measures of central tendency for the variables of a quantitative nature and frequency distribution for those categorical variables. The behavior of the variables was revealed through the Shapiro-Wilk statistic. The mean difference analysis was carried out with the Student’s T for independent samples. To identify the effect of gender, age, and severity of the disease on the study variables, a three-way analysis of variance was obtained with a Sidak comparison analysis. For the associations between qualitative and dichotomous nature variables, the Chi-Square statistic was obtained along with the odds ratio to determine the intensity of the relationships found. Results: A total of 90 patients were included in the analysis; 71% (64) were female and 29% (26) were male; with a mean age of 62.7 years old (± 30.5). A mean BMI of 33.2, 79.9% (77) of patients reached overweight and obesity ranges. 50% (45) of patients reported disability to perform one or more daily life activities related to the disease’s condition (signs, symptoms, volume). Only 12% (10) of all patients performed at or above the minimum physical activity recommended for their population group, and 88% (80) of patients had no physical activity or performed under the proper population group’s recommendation of minimal physical activity. It was found that the practice of physical activity, the number of compromised segments, the stage of the pathology, and the presence of cardiological and metabolic antecedents provide a statistically significant association with disability. Notable statistical difference among sex as a risk factor was not found. Regarding the BMI, the only differences were observed in the level of severity of the disease, regardless of the presence of any disability (p=0.006), evidencing that the greater the severity, the higher the BMI in both men and women. About physical activity, it is observed that inactivity or minimal practice of physical activity is a risk factor for referred disability (p<0.05), since it is prolonged that the non-practice of physical activity increases by 230% the chances of referring a disability associated to the disease compared to those people who referred to practice minimal or above minimal physical activity; the presence of a cardiological and/or metabolic history is related to an increase of about 150% to 180% of presenting disability compared to patients who do not have these pathologies. Conclusion: This study shows clinical and epidemiological features of phlebolymphedema and their relationship with the level of physical activity and reported disability of 90 patients. Further studies are needed to improve and broaden the understanding of the clinical characteristics of phlebolymphedema and its correlations.

Eighty-one patients randomly allocated to two groups (41 patients in Group 1 and 40 patients in Group 2). Dilution of phenylephrine 5% and Tropicamide 0.8% mixture was applied to patients of Group A in both eyes and dilution of phenylephrine 2.5% and Tropicamide 0.4% mixture was applied to Group B patients in both eyes. Pupil diameter and pulse rate BP were measured and compared. Results: Mean age of Group 1 patients was 55.39 ± 11.47 and Group 2 was 49.95 ± 13.71. Among 36 males, 50% in Group 1 and 50% in Group 2 and among 45 females 51.1% in Group 1 and 48.9% in Group 2. Among both Group 1 and Group 2 patients, both left and right pupil size was significantly increased after application of dilutions, but there was more increase in the pupil size among Group 1 patients compared to Group 2 patients 15 min after and 30 min after application of drug. Conclusions: The combination of 0.8% tropicamide and 5% phenylephrine was effective compared to alternate application of 0.4% tropicamide and 2.5% phenylephrine for rapid and sustainable pupil dilatation for indirect ophthalmoscopy.

High dependency unit reduce ICU readmission rate in patients with severe liver disease: A clinical study / 中华肝脏病杂志

Objective: To explore the difference in intensive care unit (ICU) readmission rate between high dependency unit (HDU) and general ward for the patients with severe liver disease (SLD), and reflect the effect of HDU on SLD patientse. Methods: A clinical cohort of patients transferred out of ICU was established, and patients with severe liver disease who were transferred to HDU& general ward from July 2017 to December 2021 in the intensive care Unit of the Fifth Medical Center of PLA General Hospital were continuously enrolled. The main liver function indexes and MELD scores between the two groups were compared. Analyze the differences in severity and ICU readmission rate of SLD patients transferred to different wards, and clarify the role of HDU in the management of SLD patient. Area under the receiver operating characteristic (AUROC) was used to investigate the value of MELD score in predicting the occurrence of return to ICU. Results: The level of INR, TB, ALT and MELD scores of SLD patients transferred to HDU were significantly higher than those of patients transferred to general ward (all P < 0.05). MELD > 17 was found in 70.7% of SLD patients transferred to HDU group, while MELD ≤ 17 was found in 61.9% of SLD patients in general ward group. The ICU readmission rate of all patients in this cohort was 11.4%. By MELD quartile stratification, patients with SLD whose MELD > 23 had a significantly higher ICU readmission rate (20.0%) than those with SLD whose MELD ≤ 23 (8.6%) (P = 0.020). The ICU readmission rate was 8.2% when MELD ≤ 23 in the HDU group and 9.1% when MELD > 23, showing no significant difference (P = 1.000). The ICU readmission rate was 8.8% when MELD ≤ 23 in the general ward group. ICU reentry rate increased significantly to 36.4% when MELD > 23 (P = 0.001). MELD Score predicts that the optimal cut-off value of SLD patients in general ward readmitted to ICU was 23.5. Conclusion: The high dependency unit could better admit patients with SLD who were transferred out of ICU and required step-down treatment, and significantly reduced the ICU readmission rate of patients with SLD who were transferred out of ICU with MELD > 23. The patients with SLD and MELD score > 23 are suitable to be transferred from ICU to HDU.

Arbuscular mycorrhizal fungi activity in the rhizosphere of tree seedlings subjected to residual herbicides / Atividade de fungos micorrízicos arbusculares na rizosfera de mudas de árvores submetidas a herbicidas residuais

Trees occurring on the margins of agricultural areas can mitigate damage from residual herbicides. Rhizospheric microbial activity associated with trees is one of the main remedial capacity indicators. The objective of this study was to evaluate the rhizospheric microbiological activity in tree species subjected to the herbicides atrazine and sulfentrazone via the rhizosphere. The experiment was designed in four blocks and a 6 × 3 factorial scheme. The first factor consisted of six tree species from Brazil and the second of atrazine, sulfentrazone, and water solutions. Four herbicide applications were performed via irrigation. The total dry mass of the plants, mycorrhizal colonization, number of spores, basal respiration of the rhizospheric soil, and survival rate of bioindicator plants after phytoremediation were determined. Trichilia hirta had higher biomass when treated with atrazine and sulfentrazone. Herbicides decreased the microbial activity in Triplaris americana and did not affect the microbiological indicators of Myrsine gardneriana, Schizolobium parahyba, and Toona ciliata. Fewer bioindicator plants survived in soil with Triplaris americana and sulfentrazone. Microbiological indicators were influenced in different ways between species by the presence of herbicides in the rhizosphere.

As árvores que ocorrem nas margens das áreas agrícolas podem mitigar os danos dos herbicidas residuais. A atividade microbiana rizosférica associada às árvores é um dos principais indicadores de capacidade corretiva. O objetivo deste trabalho foi avaliar a atividade microbiológica rizosférica em espécies arbóreas submetidas aos herbicidas atrazina e sulfentrazone via rizosfera. O experimento foi estruturado em quatro blocos e esquema fatorial 6 × 3. O primeiro fator consistiu em seis espécies de árvores do Brasil e o segundo em soluções de atrazine, sulfentrazone e água. Quatro aplicações de herbicidas foram realizadas via irrigação. Foram determinados a massa seca total das plantas, colonização micorrízica, número de esporos, respiração basal do solo rizosférico e taxa de sobrevivência de plantas bioindicadoras após fitorremediação. Trichilia hirta apresentou maior biomassa quando tratada com atrazina e sulfentrazone. Os herbicidas diminuíram a atividade microbiana em Triplaris americana e não afetaram os indicadores microbiológicos de Myrsine gardneriana, Schizolobium parahyba e Toona ciliata. Menos plantas bioindicadoras sobreviveram no solo com Triplaris americana e sulfentrazone. Os indicadores microbiológicos foram influenciados de formas distintas entre as espécies pela presença dos herbicidas na rizosfera.

Evaluation of nutritional composition of flour residue of mangaba processing / Avaliação dos fatos nutricionais do processamento do resíduo da farinha de mangaba

Among several fruits, mangaba (Hancornia speciosa Gomes), it aroused the interest of producers and consumers due to its attractive sensory characteristics and health beneficial properties (high nutritional value and presence of bioactive substances), thus, this work evaluates the nutritional factors of the flour residue of mangaba processing that is despised by the food industry, and the influence of temperature on its production. The mangaba processing residue was splited in two main groups: in natura sample (control), and other for preparation of flour that was dried at 50 °C and divided into two other groups: treatment A (flour with roasts at 110 °C and 130 °C) and treatment B (flour from drying at 50 °C). The nutritional characteristics of flours were analyzed considering the chemical parameters: pH, titratable total acidity and soluble solids, in addition to the determination of moisture content, total lipids, total dietary fiber and ash, total energy value, antioxidant activity, phytochemical screening, quantification of phenolic compounds and flavonoids, as well as technological functional properties (water absorption index (WAI), water solubility index (WSI), milk absorption index (MAI) and milk solubility index (MSI) and oil absorption index (OAI). The results showed that the bioactive compounds present in the extracts do not have significant properties of acting as free radical kidnappers. The heat treatment, performed in the flour of mangaba processing residues, influenced the nutritional factors and properties of absorption and solubility, which showed statistical differences. These results show that the flour is a viable alternative for the energy enrichment of diets, contributing to the development of new products, the reduction of the disposal of these residues and consequently to the minimization of the environmental impact.

Dentre as diversas frutas a mangaba (Hancornia speciosa Gomes), despertou interesse de produtores e consumidores devido às suas características sensoriais atrativas e propriedades benéficas à saúde (elevado valor nutricional e presença de substâncias bioativas), assim, o trabalho avaliar os fatores nutricionais do resíduo da farinha de processamento de mangaba que é desprezado pela indústria alimentícia e, a influência da temperatura na sua produção. O resíduo de processamento da mangaba foi dividido em dois lotes, sendo um deles utilizado para as análises in natura (amostra controle) e o outro para a confecção da farinha que foi seca a 50 °C, e dividida em dois lotes: tratamento A (farinha com torras a 110 °C e 130 °C) e no tratamento B (farinha oriunda da secagem a 50 °C). Analisou-se as características nutricionais de farinhas considerando os parâmetros químicos: pH, acidez total titulável e sólidos solúveis, além da determinação do teor de umidade, lipídios totais, fibra alimentar total e cinzas, valor energético total, atividade antioxidante, triagem fitoquímica, quantificação de compostos fenólicos e flavonoides, bem como as propriedades funcionais tecnológicas (índice de absorção de água (IAA), índice de solubilidade em água (ISA), índice de absorção de leite (IAL) e índice de solubilidade em leite (ISL) e índice de absorção de óleo (IAO). Na análise foi inferido que os compostos bioativos presentes nos extratos não possuem propriedades significativas de agir como sequestradores de radicais livres. O tratamento térmico, realizado na farinha de resíduos de processamento de mangaba, influenciou nos dados dos fatores nutricionais e das propriedades de absorção e solubilidade, os quais apresentaram diferenças estatísticas. Estes resultados credenciam a farinha como uma alternativa viável para o enriquecimento energético de dietas, contribuindo para o desenvolvimento de [...].
