RESUMEN
The concentration of atmospheric CO2 and temperature are pivotal components of ecosystem productivity, carbon balance, and food security. In this study, we investigated the impacts of a warmer climate (+2 °C above ambient temperature) and an atmosphere enriched with CO2 (600 ppm) on gas exchange, antioxidant enzymatic system, growth, nutritive value, and digestibility of a well-watered, managed pasture of Megathyrsus maximus, a tropical C4 forage grass, under field conditions. Elevated [CO2] (eC) improved photosynthesis and reduced stomatal conductance, resulting in increased water use efficiency and plant C content. Under eC, stem biomass production increased without a corresponding increase in leaf biomass, leading to a smaller leaf/stem ratio. Additionally, eC had negative impacts on forage nutritive value and digestibility. Elevated temperature (eT) increased photosynthetic gains, as well as stem and leaf biomass production. However, it reduced P and K concentration, forage nutritive value, and digestibility. Under the combined conditions of eC and eT (eCeT), eT completely offset the effects of eC on the leaf/stem ratio. However, eT intensified the effects of eC on photosynthesis, leaf C concentration, biomass accumulation, and nutritive value. This resulted in a forage with 12% more acid detergent fiber content and 28% more lignin. Additionally, there was a decrease of 19% in crude protein leading to a 15% decrease in forage digestibility. These changes could potentially affect animal feeding efficiency and feedback climate change, as ruminants may experience an amplification in methane emissions. Our results highlight the critical significance of conducting multifactorial field studies when evaluating plant responses to climate change variables.

RESUMEN
OBJECTIVE: To translate, culturally adapt, and validate a version of the ID Migraine into Latin American Spanish. BACKGROUND: Although still considered a common diagnosis, half of the patients with migraine in Latin America experience diagnostic delay. The ID Migraine is a test developed in 2003 as a valuable tool for the early diagnosis of migraine at the primary care level; however, there is no validated Spanish or culturally adapted version for the Spanish-speaking population. METHODS: This is an analytical, translation, and test-validation study. We performed back translation and cross-cultural adaptation. The Latin American Spanish version ID Migraine MX was applied to headache clinic patients from March 2021 to January 2022 to perform a validation process against the gold standard: blinded expert diagnosis according to the International Classification of Headache Disorders, 3rd edition (ICHD-3), criteria. RESULTS: One hundred seventeen patients from the headache clinic of the National Institute of Neurology and Neurosurgery of Mexico City were screened. We found 62/117 (53%) patients positive for screening with ID Migraine MX, and 47/117 (40%) positive for migraine according to ICHD-3 criteria. A sensitivity (95% CI) of 0.91 (0.80-0.97), specificity of 0.73 (0.61-0.82), positive predictive value of 0.694 (0.57-0.794), and negative predictive value of 0.93 (0.83-0.97) were obtained. The positive likelihood ratio was 3.38 (2.27-4.99), and the negative likelihood ratio was 0.12 (0.04-0.30). After calling the patients 1 month after the first interview, the calculated Kappa test-retest was 0.75 (p = 0.001). CONCLUSION: A translated and cross-culturally adapted version into Spanish of the ID Migraine was obtained, with a diagnostic performance similar to the original instrument. Clinicians may use this test at the first level of care to reduce the rate of misdiagnosis and the time from onset of symptoms to diagnosis and treatment of migraine.

A model for cross-over designs with repeated measures within each period was developed. It was obtained using an extension of generalized estimating equations that includes a parametric component to model treatment effects and a non-parametric component to model time and carry-over effects; the estimation approach for the non-parametric component is based on splines. A simulation study was carried out to explore the model properties. Thus, when there is a carry-over effect or a functional temporal effect, the proposed model presents better results than the standard models. Among the theoretical properties, the solution is found to be analogous to weighted least squares. Therefore, model diagnostics can be made by adapting the results from a multiple regression. The proposed methodology was implemented in the data sets of the cross-over experiments that motivated the approach of this work: systolic blood pressure and insulin in rabbits.

Global climate change will impact crops and grasslands, affecting growth and yield. However, is not clear how the combination of warming and increased atmospheric carbon dioxide concentrations ([CO2]) will affect the photosystem II (PSII) photochemistry and the photosynthetic tissue photoinhibition and photoprotection on tropical forages. Here, we evaluated the effects of elevated [CO2] (â¼600 µmol mol-1) and warming (+2 °C increase temperature) on the photochemistry of photosystem II and the photoprotection strategies of a tropical C4 forage Panicum maximum Jacq. grown in a Trop-T-FACE facility under well-watered conditions without nutrient limitation. Analysis of the maximum photochemical efficiency of PSII (Fv/Fm), the effective PSII quantum yield Y(II), the quantum yield of regulated energy dissipation Y(NPQ), the quantum yield of non-regulated energy dissipation Y(NO), and the malondialdehyde (MDA) contents in leaves revealed that the photosynthetic apparatus of plants did not suffer photoinhibitory damage, and plants did not increase lipid peroxidation in response to warming and [CO2] enrichment. Plants under warming treatment showed a 12% higher chlorophyll contents and a 58% decrease in α-tocopherol contents. In contrast, carotenoid composition (zeaxanthin and ß-carotene) and ascorbate levels were not altered by elevated [CO2] and warming. The elevated temperature increased both net photosynthesis rate and aboveground biomass but elevated [CO2] increased only net photosynthesis. Adjustments in chlorophyll, de-epoxidation state of the xanthophylls cycle, and tocopherol contents suggest leaves of P. maximum can acclimate to 2 °C warmer temperature and elevated [CO2] when plants are grown with enough water and nutrients during tropical autumn-winter season.

Tropical grasslands are very important to global carbon and water cycles. C4 plants have increased heat tolerance and a CO2 concentrating mechanism that often reduces responses to elevated concentrations of CO2 ([CO2]). Despite the importance of tropical grasslands, there is a scarcity of studies that elucidate how managed tropical grasslands will be affected by elevated [CO2] and warming. In our study, we used a combination of a temperature-free air-controlled enhancement (T-FACE) and a free-air carbon dioxide enrichment (FACE) systems to increase canopy temperature and [CO2] under field conditions, respectively. We warmed a field-grown pasture dominated by the C4 tropical forage grass Megathyrsus maximus by 2°C above ambient under two levels of [CO2] (ambient (aC) and elevated (eC - 600 ppm) to investigate how these two factors isolated or combined regulate water relations through stomatal regulation, and how this combination affects PSII functioning, biochemistry, forage nutritive value, and digestibility. We demonstrated that the effects of warming negated the effects of eC in plant transpiration, water potential, proline content, and soil moisture conservation, resulting in warming canceling the eCO2-induced improvement in these parameters. Furthermore, there were additive effects between eC and warming for chlorophyll fluorescence parameters and aboveground nutritive value. Warming sharply intensified the eCO2-induced decrease in crude protein content and increases in forage fibrous fraction and lignin, resulting in a smaller forage digestibility under a warmer CO2-enriched atmosphere. Our results highlight the importance of multifactorial studies when investigating global change impacts on managed ecosystems and the potential consequences for the global carbon cycle like amplification in methane emissions by ruminants and feeding a positive climate feedback system.

Temperature and soil moisture strongly affect the nutritional value and digestibility of forage plants through changes in leaf chemical composition or the proportion of leaf blade tissues. In this study, we aimed to evaluate leaf blade anatomical modifications of two tropical forage species, Stylosanthes capitata (C3) and Megathyrsus maximus (C4) under warmed conditions (+2 °C) at well-watered and rainfed conditions and investigate the interactions between leaf anatomical alterations, leaf chemical composition, and leaf digestibility. Experiments were conducted under field conditions using a Temperature-free air-controlled enhancement (T-FACE) system. We observed that plants under elevated temperature produced leaves with smaller stomata and thinner mesophyll tissue and reduced total leaf thickness, potentially impacting gas exchange. On the other hand, reduced soil moisture increased stomatal density and thickness of the adaxial epidermis. In both species, leaf fibrous fractions concentration increased under warmed and non-irrigated conditions, while crude protein concentration and digestibility decreased. However, leaf digestibility was associated with leaf chemical composition rather than the proportion of different leaf blade tissues. We concluded that although both species developed leaf anatomical modifications to acclimate under future warming conditions, leaf nutritional value and digestibility will be reduced, potentially impacting future livestock production and methane emissions by ruminants.

Abstract: Introduction: since the beginning of blood banks, refinements in laboratory processes have allowed longer red blood cell storage times. While advantageous to the logistics of stock management, the clinical impact of RBC storage duration prior to transfusion remains uncertain and a topic of growing interest. Although the structural, biochemical, and impermeable changes that red blood cells undergo during storage are well described, the evidence that this storage injury translates into adverse clinical outcomes for patients receiving blood with longer storage times remains controversial. Objective: to compare the efficacy of the transfusion of globular packages of ≤ 15 days of extraction vs. globular packages ≥ 16-40 days of extraction in the hemodynamic and gasometric repercussion of patients with severe traumatic brain injury (TBI), hospitalized in the Intensive Care Unit of HE CMNO. Material and methods: a controlled, single-center, randomized, single-blind, prospective and comparative clinical trial was conducted, where patients between 18 and 80 years of age with severe postoperative cranioencephalic trauma who required blood transfusions were invited to participate. Participants were included in two random groups, group F and group E. Group F was administered packed cells ≤ 15 days of extraction. Group E will be administered globular packages ≥ 16-40 days of extraction. During the study, various hemodynamic and biochemical variables were measured before, during, and after blood transfusion, and a comparison of the results obtained between groups F and E was subsequently made. Results: in the present study, a total of 26 patients with severe TBI were included and who were transfused with red blood cell packs, of the total number of patients, 13 were transfused with a «standard¼ red blood cell pack and another 13 patients with a «fresh¼ red blood cell pack. The average days of transfusion after extraction were 18 and 14 days for the «standard¼ and «fresh¼ packs, respectively (p ≤ 0.001). Twenty-one infectious events were reported, 11 in the group of patients who were transfused with the standard pack and 10 in the fresh pack group. Mortality at 28 days was estimated in 31% of the patients transfused with the standard pack and in 23% of the patients with the fresh pack (RR, for 28-day mortality of 0.90 [95% CI 0.56-144]). The median duration time in the intensive care unit was 8 days for both groups (0.32 SD), and of the days associated with the ventilator, 15 days were observed for the group of patients with the standard package and 7 for the group with fresh package (0.60 SD), without discovering statistically significant differences in these variables. However, in this analysis statistically significant differences were found for the gasometric parameters of central venous oxygen saturation, cardiac output (Fick) and lactate before and after transfusion in favor of the group of patients transfused with fresh pack (p ≤ 0.05). Conclusion: the results of this study infer that there is no association between the storage time of transfused red blood cells and the presence of adverse clinical outcomes with longer storage times. In both groups, transfusions were equally safe and effective. The researchers refer to the sample size as a limitation for this study.
Resumo: Introdução: desde o surgimento dos bancos de sangue, o refinamento dos processos laboratoriais permitiu tempos de estocagem cada vez mais longos para as hemácias. Embora vantajoso para a logística do gerenciamento de estoque, o impacto clínico da duração do armazenamento de glóbulos vermelhos antes da transfusão permanece incerto e um tópico de interesse crescente. Embora as alterações estruturais, bioquímicas e imunológicas pelas quais as hemácias sofrem durante o armazenamento sejam bem descritas, as evidências de que essa lesão de armazenamento resulta em resultados clínicos adversos para pacientes que recebem sangue armazenado por mais tempo permanecem controversas. Objetivo: comparar a eficácia da transfusão de concentrado de hemácias ≤ 15 dias de extração vs concentrado de hemácias ≥ 16-40 dias de extração nas repercussão hemodinâmica e gasométrica dos pacientes com traumatismo cranioencefálico (TCE) grave, internados em Unidade de Terapia Intensiva do HE CMN Occidente. Material e métodos: realizou-se um ensaio clínico, controlado, unicêntrico, randomizado, simples-cego, prospectivo e comparativo, onde foram convidados a participar pacientes com idade entre 18 e 80 anos com traumatismo cranioencefálico grave submetidos a hemicraniectomia descompressiva com necessidade de transfusão sanguínea. Os participantes foram incluídos aleatoriamente em 2 grupos, grupo F e grupo E. Grupo F recebeu concentrado de hemácias ≤ 15 dias após a extração. O grupo E receberá concentrado de hemácias ≥ 16-40 dias após a extração. Durante o estudo, várias variáveis hemodinâmicas e bioquímicas foram medidas antes, durante e após a transfusão de sangue, e posteriormente foi feita uma comparação dos resultados obtidos entre os grupos F e E. Resultados: no presente estudo incluíram-se um total de 26 pacientes com TCE grave e que foram transfundidos com concentrado de hemácias, do total de pacientes 13 foram transfundidos com um concentrado de hemácias «padrão¼ e outros 13 pacientes com um concentrado de hemácias «fresco¼. A média de dias de transfusão após a extração foi de 18 e 14 dias para as pacotes «padrão¼ e «fresco¼, respectivamente (p ≤ 0.001). Relatou-se 21 eventos infecciosos, 11 no grupo de pacientes que receberam transfusão com concentrado padrão e 10 no grupo com concentrado fresco. A mortalidade em 28 dias foi estimada em 31% dos pacientes transfundidos com concentrado padrão e em 23% dos pacientes com concentrado fresco (RR, para mortalidade em 28 dias de 0.90 (IC 95% 0.56-144). A duração mediana na unidade de terapia intensiva foi de 8 dias para ambos os grupos (0.32 DP), sendo que 2 dias associados ao ventilador, foram observados 15 dias para o grupo de pacientes com concentrado padrão e 7 para o grupo de concentrado fresco (0.60 DE), sem descobrir diferenças estatisticamente significativas nas referidas variáveis.No entanto, nesta análise foram encontradas diferenças estatisticamente significativas para os parâmetros gasométricos de saturação venosa central de oxigênio, débito cardíaco (Fick) e lactato antes e após a transfusão em favor do grupo de pacientes transfundidos com concentrado fresco (p ≤ 0.05). Conclusão: os resultados deste estudo inferem que não há associação entre o tempo de estocagem das hemácias transfundidas e a presença de desfechos clínicos adversos com tempos de estocagem mais longos. Em ambos os grupos, as transfusões foram igualmente seguras e eficazes. Os pesquisadores referem-se ao tamanho da amostra como limitante para este estudo.
RESUMEN
The climate changes expected for the next decades will expose plants to increasing occurrences of combined abiotic stresses, including drought, higher temperatures, and elevated CO2 atmospheric concentrations. These abiotic stresses have significant consequences on photosynthesis and other plants' physiological processes and can lead to tolerance mechanisms that impact metabolism dynamics and limit plant productivity. Furthermore, due to the high carbohydrate content on the cell wall, plants represent a an essential source of lignocellulosic biomass for biofuels production. Thus, it is necessary to estimate their potential as feedstock for renewable energy production in future climate conditions since the synthesis of cell wall components seems to be affected by abiotic stresses. This review provides a brief overview of plant responses and the tolerance mechanisms applied in climate change scenarios that could impact its use as lignocellulosic biomass for bioenergy purposes. Important steps of biofuel production, which might influence the effects of climate change, besides biomass pretreatments and enzymatic biochemical conversions, are also discussed. We believe that this study may improve our understanding of the plant biological adaptations to combined abiotic stress and assist in the decision-making for selecting key agronomic crops that can be efficiently adapted to climate changes and applied in bioenergy production.

Abstract: Introduction: Traumatic brain injury (TBI) is a medical-surgical condition characterized by brain involvement secondary to a traumatic lesion. Patients with severe TBI are at high risk of mortality and this will depend on different factors such as the presence of intracranial hypertension, age, origin of the injury and score on the Glasgow coma scale. Measurement of the optic nerve sheath diameter (ONSD) appears to be a good indirect indicator of intercranial hypertension and therefore, a good predictor of mortality. Objective: To determine the most appropriate cut-off point, as well as the measurement of the ONSD usefulness as a prognostic indicator of mortality in patients with severe TBI in the Intensive Care Unit (ICU). Material and methods: This is an analytical, descriptive, and retrospective study. The universe of study consists of all the case/files with TBI. For the sample selection, all available records of patients with severe TBI sent to the ICU during the period from March 1 to August 31, 2021, will be included. Within the inclusion criteria patients with a Glasgow scale score of < 8 points on entry and with a computerized scan done. The dependent variables to considerer are the outcome understood as death or survival of the patient, the days hospitalized in the ICU, the presence of complications; among the dependent variables is the diameter of the optic nerve sheath measured by computerized tomography. Intervening variables were also considered such as the presence of comorbidities and overweight/obesity, the age and sex of the patient. The project consisted of four phases: 1) request for authorization and access to files, 2) application of selection criteria, 3) performance of ONSD measurements and 4) creation of the database. Finally, once the database is formed, the statistical analysis will proceed; for the descriptive part, prevalence's, means (standard deviation) and medians (percentiles) will be calculated for the variables by sex and by outcome, subsequently the diagnostic capacity of the ONSD will be analyzed through the area under the ROC curve (receiving operating characteristics) for the outcome. Afterwards the performance of this and other cut-off points are compared using the Youden index. Results: Sixty records of TBI patients admitted to the ICU were studied, 51 were men (85%), 45 patients survived (75%) and 15 patients died (25%). The average age was of 50.5 ± 10.6 years, the average Glasgow score on admission was 6.6 ± 1.6 points, the average BMI was 26.42 ± 4.10 kg/m2, and the average number of days spent in the ICU was 9.03 ± 6.4. The diameter of the optic nerve was not a predictor of mortality, but if the Glasgow coma scale was, with an AUC of 0.775 (95% CI: 0.648-0.901, p = 0.002), the best cut-off point was 7 with a sensitivity of 93% and specificity of 54%. The bivariate linear regression model points to low Glasgow coma score and long hospital stay as predictors of mortality. Conclusions: The results of this study infer that, consistent with current scientific evidence, the sociodemographic characteristics of our population are similar to those reported by other authors, with men over 50 years of age being the most affected by this entity. On the other hand, the measurement of the diameter of the optic nerve sheath has been considered a good prognostic indicator of intracranial hypertension, which in turn is associated with increased mortality. However, in the present study there is no association between the diameter of the optic nerve sheath and the prognosis of mortality.
Resumo: Introdução: O traumatismo cranioencefálico (TCE) é uma condição médico-cirúrgica caracterizada por lesão cerebral secundária a uma lesão traumática. Pacientes com TCE grave apresentam alto risco de mortalidade e isso dependerá de diversos fatores, como presença de hipertensão intracraniana, idade, origem da lesão e pontuação na Escala de Coma de Glasgow. A medida do diâmetro da bainha do nervo óptico (DBNO) parece ser um bom indicador indireto de hipertensão intracraniana e, portanto, um bom preditor de mortalidade. Objetivo: Determinar o ponto de corte mais adequado, bem como a utilidade da medida do DBNO como indicador prognóstico de mortalidade em pacientes com TCE grave na Unidade de Terapia Intensiva. Material e métodos: Trata-se de um estudo analítico, descritivo e retrospectivo. O universo de estudo é composto por todos os prontuários de casos/pacientes com TCE grave. Para a seleção da amostra foram incluídos todos os prontuários disponíveis de pacientes com TCE grave encaminhados à Unidade de Terapia Intensiva no período de 1o de março a 31 de agosto de 2021, dentro dos critérios de inclusão foram considerados pacientes com escala de Glasgow < 8 pontos na admissão e com uma tomografia computadorizada realizada. As variáveis dependentes consideradas são o desfecho entendido como óbito ou sobrevida do paciente, os dias de internação na UTI, a presença de complicações; dentro das variáveis independentes está o diâmetro da bainha do nervo óptico medido por tomografia computadorizada. Também foram consideradas variáveis intervenientes, como presença de comorbidades e sobrepeso/obesidade, idade e sexo do paciente. O projeto consistiu em três fases: a) Pedido de autorização e acesso aos prontuários, b) Aplicação dos critérios de seleção, c) Desenvolvimento da base de dados. Por fim, uma vez formada a base de dados, procedeu-se à análise estatística. Para a parte descritiva, foram calculadas as prevalências, médias (desvio padrão) e medianas (percentis) das variáveis por sexo e por desfecho. Posteriormente, a capacidade diagnóstica do DBNO foi analisada pela área sob a curva ROC (Receiving Operating Characteristics) para o resultado. Posteriormente, o desempenho deste e de outros pontos de corte foi comparado pelo índice de Youden. Resultados: Foram estudados 60 prontuários de pacientes com TCE que deram entrada na UTI, 51 eram homens (85%), 45 pacientes sobreviveram (75%) e 15 pacientes morreram (25%). A média de idade foi de 50.5 ± 10.6 anos, a média de Glasgow na admissão foi de 6.6 ± 1.6 pontos, a média de IMC foi de 26.42 ± 4.10 kg/m2 e a média de dias de internação na UTI foi de 9.03 ± 6.4. O diâmetro do nervo óptico não foi preditor de mortalidade, mas a Escala de Coma de Glasgow sim, com AUC de 0.775 (IC 95%: 0.648-0.901, p = 0.002), o melhor ponto de corte foi 7 com sensibilidade de 93% e especificidade de 54%. O modelo de regressão linear bivariada aponta para baixo escore de coma de Glasgow e longa permanência hospitalar como preditores de mortalidade. Conclusões: Os resultados deste estudo inferem que, de acordo com as evidências científicas atuais, as características sociodemográficas de nossa população são semelhantes às relatadas por outros autores, sendo os homens com aproximadamente 50 anos de idade os mais acometidos por essa entidade. Por outro lado, a medida do diâmetro da bainha do nervo óptico tem sido considerada um bom indicador prognóstico de hipertensão intracraniana, que por sua vez está associada ao aumento da mortalidade. No entanto, no presente estudo não há associação entre o diâmetro da bainha do nervo óptico e o prognóstico de mortalidade.
RESUMEN
Since laccase acts specifically in lignin, the major contributor to biomass recalcitrance, this biocatalyst represents an important alternative to the pretreatment of lignocellulosic biomass. Therefore, this study investigates the laccase pretreatment and climate change effects on the hydrolytic performance of Panicum maximum. Through a Trop-T-FACE system, P. maximum grew under current (Control (C)) and future climate conditions: elevated temperature (2 °C more than the ambient canopy temperature) combined with elevated atmospheric CO2 concentration(600 µmol mol-1), name as eT+eC. Pretreatment using a laccase-rich crude extract from Lentinus sajor caju was optimized through statistical strategies, resulting in an increase in the sugar yield of P. maximum biomass (up to 57%) comparing to non-treated biomass and enabling hydrolysis at higher solid loading, achieving up to 26 g L-1. These increments are related to lignin removal (up to 46%) and lignin hydrophilization catalyzed by laccase. Results from SEM, CLSM, FTIR, and GC-MS supported the laccase-catalyzed lignin removal. Moreover, laccase mitigates climate effects, and no significant differences in hydrolytic potential were found between C and eT+eC groups. This study shows that crude laccase pretreatment is a potential and sustainable method for biorefinery solutions and helped establish P. maximum as a promising energy crop.

To investigate the in vitro anthelmintic efficacy of dividivi (Caesalpinia coriaria), a traditional medicinal plant used in Central America and the northern part of South America, extracts from the foliage of this plant were subjected to the egg hatching test (EHT) and larval exsheathment inhibition test (LEIT), against Haemonchus contortus. Four different extracts were evaluated: acetone-water (AW), methanol-water (MW), acetone-water-dichloromethane (AWD) and methanol-water-dichloromethane (MWD). The concentrations used for the EHT and LEIT tests ranged from 500 to 4000 µg mL-1 and six repetitions per concentration. The effective concentrations (EC50) were calculated using Probit analysis. The EC50 for EHT were 2947.0, 3347.0, 3959.6 and 4538.7 µg mL-1 for MWD, MW, AW and AWD, respectively. The EC50 for LEIT were 2883.4, 5927.4, 9876.3 and 9955.4 µg mL-1 for AWD, AW, MWD and MW, respectively. The methanol extracts were the most effective in inhibiting the hatching of eggs, while the acetone extracts showed efficacy in inhibiting larval exsheathment. This study explains the importance that C. coriaria has as a medicinal plant in Central and South American countries.

In tropical and subtropical zones, lianas play important roles in the process of ecological succession. This study aims to evaluate the photosynthetic and morpho-physiological performance between two lianas species from Mikania genus in response to different levels of radiation: full sun (I0), 25% (I25), 50% (I50), and 75% (I75) retention of solar radiation flux. Plants grown under I75 showed a reduced net photosynthetic rate (A). We observed dynamic photoinhibition at I0 during hours of high irradiation and temperature. The highest and lowest leaf chlorophyll content occurred at I75 and I0, respectively, while carotenoids/total chlorophyll and leaf thickness increased under I0. Total dry mass was higher in plants grown at I0 and I25. However, A values and biomass production of Mikania laevigata were higher at I25, while for Mikania glomerata greater biomass accumulation was observed between I0-I50. Therefore, we concluded that M. laevigata and M. glomerata have different morpho-physiological performances under same the radiation conditions.
Em regiões tropical e subtropical, lianas desempenham um papel importante no processo de sucessão ecológica. O objetivo deste estudo foi avaliar as respostas fotossintéticas e morfo-fisiológicas entre duas espécies de Mikania em diferentes níveis de radiação: sol pleno (I0), 25% (I25), 50% (I50) e 75% (I75) de retenção do fluxo da radiação solar. Plantas crescidas sob I75 mostraram reduzida taxa fotossintética (A). Nós observamos fotoinibição dinâmica em plantas crescidas sob I0 durante as horas de alta irradiação e temperatura. O maior e menor conteúdo de clorofila ocorreu em plantas sob I75 e I0, respectivamente; enquanto carotenoides/clorofila total e espessuras da epiderme e mesofilo aumentaram sob I0. A massa seca total foi maior em plantas crescidas sob I0 e I25. No entanto, os valores de A e a produção de biomassa de M. laevigata foram maiores sob I25; enquanto para M. glomerata, maior acúmulo de biomassa foi observado entre I0-I50. Portanto, nós concluímos que M. laevigata e M. glomerata apresentaram diferentes respostas morfo-fisiológicas sob mesma condição de radiação.
RESUMEN
RESUMEN Los efectos de diferentes agroquímicos y de la temperatura han sido temas recurrentes en la investigación en anuros; sin embargo, estas variables se han abordado de manera independiente sin considerar que pueden ejercer una presión simultánea sobre las especies. Por esta razón, este trabajo tiene como objetivo determinar la toxicidad (a través de la Concentración Letal Media -CL50) de los insecticidas organofosforados clorpirifos, diazinón y monocrotofos, bajo tres regímenes térmicos (23, 28 y 33 ± 1 °C) sobre embriones de tres especies de anuros. De acuerdo a los valores de CL50, el insecticida clorpirifos fue el más tóxico, seguido del diazinón y del monocrotofos. Por su parte, de manera general se encontró un incremento de la toxicidad de los insecticidas organofosforados a la temperatura más alta de experimentación (33 °C). Además, el efecto de la temperatura se hizo más notorio para los organismos expuestos al clorpirifos, el insecticida más letal. Estos resultados sugieren un efecto negativo para la fauna acuática de anuros debido al actual uso desmesurado de este tipo de agroquímicos y a su interacción con la temperatura ambiental.
ABSTRACT In anurans, the effects of different agrochemicals and temperature have been recurrent topics in research; however, these variables are addressed independently without considering that they can exert a simultaneous pressure on the species. For this reason, this work aims to determine the toxicity (through the Medium Lethal Concentration -LC50) of the organophosphate insecticides: chlorpyrifos, diazinon and monocrotophos, under three thermal regimes (23, 28 and 33 ± 1 °C) on embryos ofthree species of anurans. According to the LC50 values, the chlorpyrifos insecticide was the most toxic, followed by diazinon and monocrotophos. On the other hand, an increase in the toxicity of the organophosphate insecticides studied was generally found at the highest experimental temperature (33 °C). In addition, the effect of temperature became more noticeable for the organisms exposed to chlorpyrifos, the most lethal insecticide. These results suggest a negative effect for the aquatic fauna of anurans due to the current excessive use of this type of agrochemicals and their interaction with environmental temperature.
RESUMEN
RESUMEN Introducción: la prejubilación es un proceso de relevancia social por la alta tasa de crecimiento de la población activa envejecida, cuya preocupación más relevante surge por la extensión, quizás sobredimensionada, de la vida laboral. Objetivo: determinar los resultados de la musicoterapia en personas prejubilables. Métodos: se realizó una intervención musicoterapéutica con el objetivo de regular las emociones en personas prejubilables, ante el dilema del cese del vínculo laboral o la continuidad de este; se realizó un estudio cuasi-experimental en el Policlínico Docente «Marta Abreu¼, Villa Clara, en el período de enero 2017 a febrero 2019. Se emplearon procedimientos, métodos y técnicas con aplicación de la musicoterapia en un grupo estudio de 200 personas prejubilables, de 55 a 65 años de edad. Se utilizaron métodos teóricos, empíricos y estadísticos-matemáticos. Se aplicaron técnicas psicológicas antes y después de la musicoterapia en el grupo estudio y en el grupo control. Resultados: se constataron resultados relevantes en el grupo estudio, y se registraron cambios muy significativos: más estados emocionales ansiosos bajo y depresivo leve, autoestima alta, y notable mejoría en la vulnerabilidad al estrés. En el grupo control no se reflejaron cambios favorables. Conclusiones: la musicoterapia resultó efectiva por el logro de cambios positivos en el estado emocional en personas prejubilables del grupo estudio. La identificación prometedora de potencialidades en el lenguaje musical, con la utilización mínima de la palabra en la atención integral a personas en etapa de prejubilación, constituyó una novedad.
ABSTRACT Introduction: early retirement is a process of social relevance due to the high growth rate of the aging workforce, whose most relevant concern arises from the extension, perhaps oversized, of working life. Objective: to determine the results of music therapy in early retired people. Methods: a music therapy intervention was carried out with the aim of regulating emotions in early retired people, faced with the dilemma of the termination of the employment relationship or its continuity; a quasi-experimental study was carried out at "Marta Abreu" Teaching Polyclinic, Villa Clara, from January 2017 to February 2019. Procedures, methods and techniques with application of music therapy were used in a study group of 200 early retired people aged 55 to 65 years. Theoretical, empirical and statistical-mathematical methods were used. Psychological techniques were applied in the study group before and after music therapy and in the control group without intervention. Results: relevant results were found in the study group, and very significant changes were recorded: more low anxiety and mild depressive emotional states, high self-esteem, and notable improvement in vulnerability to stress. No favorable changes were reflected in the control group. Conclusions: music therapy was effective for achieving positive changes in emotional state in early retired people from the study group. The promising identification of potentialities in musical language, with the minimum use of spoken language in comprehensive care for people in early retirement, was a novelty.
