Limitations on the ethno-directed approach as a tool for the selection of medicinal plants with antimicrobial activity / Limitaciones en el uso del enfoque etnodirigido como herramienta para la selección de plantas antimicrobianas

In this work, we evaluate the antimicrobial properties of three groups of plants selected by the ethnopharmacological method, reported ashaving antimicrobial and/or anti-inflammatory properties by a rural community in the Brazilian State of Pernambuco. The samples were divided into groups of seven plants reported as having antimicrobial properties (GI), another seven as having anti-inflammatory properties (GII) and eight plants reported to have both (GIII). The antimicrobial properties of these groups were compared using the disc-diffusion method for nine microorganisms: Gram-positive and Gram-negative bacteria, acid-alcohol resistant bacillus (BAAR) and yeast. Among the samples of GI, 28.6% demonstrated activity against the micro-organisms tested, compared with 57.1% for the GII plants and 100% of GIII. This study shows, then, that the selected species should be looked more carefully that greater care should be taken in selecting species recommended by ethnopharmacological reports for studies of antimicrobial properties, since plants reported to have anti-inflammatory properties may be more active than those reported as being antimicrobial.

Evaluar la actividad antimicrobiana de tres grupos de plantas seleccionadas por el método etnodirigido, citadas como antimicrobianas y/o antiinflamatorias por una comunidad rural del estado de Pernambuco, Brasil. Las muestras de las especies seleccionadas fueron divididas en grupos de siete plantas citadas como antimicrobianas (GI), siete plantas citadas como antiinflamatorias (GII) y otro grupo con ocho plantas citadas para ambas situaciones (GIII). Se realizó una comparación de las actividades antimicrobianas de estos grupos mediante el método de difusión en disco frente a nueve microorganismos: Gram-positivos, Gram-negativos, bacilos ácido-alcohol resistentes (BAAR) y levadura. De las plantas citadas como antimicrobianas (GI), el 28,6% mostró actividad frente a los microorganismos probados, mientras que de las plantas pertenecientes al GII, el 57,1% presentó actividad y todas las plantas citadas para ambas situaciones (GIII) fueron activas en un 100%. Se necesita tener cuidado en la selección de especies provenientes del enfoque etnodirigido para estudios que buscan actividad antimicrobiana, ya que las plantas citadas como antiinflamatorias fueron más activas que las citadas como antimicrobianas.

Association between bullying victimization and health risk behavior in adolescents / Associação entre vitimização de bullying e comportamentos de risco à saúde em adolescentes

ABSTRACT Objective: The aim of this study was to examine the association between bullying victimization and health risk behaviors in adolescents. Methods: A representative sample of 1020 adolescents participated in the study. The variables such as bullying, health risk behaviors (tobacco, drugs, alcohol, sedentary behavior, smartphone use, level of physical activity, and sleep), and economic status were assessed using self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using binary logistic regression and ordinal, gross, and adjusted logistic regression (p<0.05). Results: Victims of bullying were more likely to smoke (OR 1.75; 95%CI 1.28-2.40), consume alcohol (OR1.43; 95%CI 1.05-1.94), have worse sleep quality (OR 1.94; 95%CI 1.28-2.91), and more sedentary behavior (OR 1.43; 95%CI 1.08-1.89) than those who were not bullied. However, victims were more likely to have high levels of physical activity than their non-bullied peers (OR 1.66; 95%CI 1.22-2.27). Conclusions: Bullying victimization was associated with an increased predisposition for the adoption of health risk behaviors. Interestingly, victims were also more prone to participate in physical activity.

RESUMO Objetivo: Examinar a associação entre vitimização por bullying e comportamentos de risco à saúde em adolescentes. Métodos: Uma amostra representativa de 1.020 adolescentes participou do estudo. As variáveis bullying, comportamentos de risco à saúde (tabaco, drogas, álcool, comportamento sedentário, uso de smartphone, nível de atividade física, sono) e situação econômica foram avaliadas por meio de questionários autorreportados. Razões de chance com intervalos de confiança de 95% (IC95%) foram obtidas por meio de regressão logística binária e regressão logística ordinal, bruta e ajustada (p<0,05). Resultados: As vítimas de bullying apresentaram maior probabilidade de fumar (OR 1,75; IC95% 1,28-2,40), consumir álcool (OR 1,43; IC95% 1,05-1,94), ter pior qualidade de sono (OR 1,94; IC95% 1,28-2,91) e apresentar mais comportamento sedentário (OR 1,43; IC95% 1,08-1,89) do que aqueles que não sofreram bullying. No entanto, as vítimas eram mais propensas a ter níveis elevados de atividade física do que os seus pares não vítimas de bullying (OR 1,66; IC95% 1,22-2,27). Conclusões: A vitimização por bullying esteve associada ao aumento da predisposição para a adoção de comportamentos de risco à saúde. Curiosamente, as vítimas também eram mais propensas a participar de atividades físicas.

Esta correlación es evidente en ambas direcciones: puntuación de calidad de vida a Escala Mini-Mental y viceversa. Conclusión: Al evaluar la calidad de vida de los ancianos que viven en residencias, el deterioro cognitivo y un índice de masa corporal (IMC) elevado parecen afectar la calidad de vida general.

Acústica de un ensamblaje de anuros del valle geográfico del río Cauca, Colombia / Acoustics of an assembly of anurans in the geographical Cauca River Valley, Colombia

Resumen Introducción: La comunicación acústica es esencial en las comunidades de anuros, especialmente para la reproducción. No obstante, el espacio acústico es limitado y las interferencias bioacústicas, como la competencia por apareamiento y recursos, afectan la eficacia de la comunicación. El bosque seco tropical en Colombia alberga especies de anuros que han sido resilientes a la gran reducción, fragmentación y transformación de este en las últimas décadas. La investigación escasa en este tema subraya la importancia de la caracterización acústica de los ensamblajes de anuros, para comprender la coexistencia de especies, monitorear cambios en la comunidad y evaluar el impacto tanto de especies invasoras como de la actividad humana en el ecosistema. Objetivo: Caracterizar acústicamente un ensamblaje de anuros del valle del río Cauca. Métodos: De septiembre a noviembre de 2022 (temporada lluviosa), se tomaron registros acústicos con sensores acústicos pasivos y activos de una comunidad de anuros del valle geográfico del río Cauca, en el flanco occidental de la cordillera central de Colombia. Se analizaron los cantos de anuncio en tres dimensiones: parámetros espectrales, temporales y patrones de actividad acústica. Resultados: Se registraron cinco especies de anuros, sus cantos presentaron un alto solapamiento en actividad, pero grandes diferencias estructurales, las especies tuvieron actividad nocturna a excepción de una de la familia Dendrobatidae. Conclusiones: Cada especie presenta un nicho acústico particular que evita el traslape en las señales acústicas, y estos resultados proporcionan una línea base para evaluar futuros cambios en el ensamblaje.

Abstract Introduction: Acoustic communication is essential in anuran communities, particularly for reproduction. However, the acoustic space is limited, and bioacoustic interferences, such as competition for mating and resources, impact the effectiveness of communication. The tropical dry forest in Colombia hosts resilient anuran species that have endured significant reduction, fragmentation, and transformation over the past decades. The scarce research on this topic underscores the importance of acoustically characterizing anuran assemblages to understand species coexistence, monitor changes in the community, and evaluate the impact of both invasive species and human activity on the ecosystem. Objective: To acoustically characterize an anuran assemblage in the Cauca River Valley. Methods: From September to November 2022 (rainy season), acoustic recordings were obtained using passive and active acoustic sensors from an anuran community in the geographical Cauca River Valley, on the western flank of the Central Cordillera in Colombia. Anuran advertisement calls were analyzed in three dimensions: spectral parameters, temporal patterns, and acoustic activity. Results: Five anuran species were recorded, exhibiting high overlap in activity but significant structural differences in their calls. The species were predominantly nocturnal, except for one from the dendrobatid family. Conclusions: Each species presents a distinct acoustic niche, avoiding overlap in acoustic signals. These findings establish a baseline for assessing future changes in the assemblage.

Morphological and biochemical characterization of Moroccan Opuntia dillenii fruit: Natural source of bioactive compounds / Caracterización morfológica y bioquímica del fruto de Opuntia dillenii marroquí: Fuente natural de compuestos bioactivos

Background: The fruit of Opuntiadillenii, commonly known as prickly pear, is widely consumed for its nutritional and medicinal benefits, such as anti-inflammatory and antioxidant properties. It plays a significant role in local diets and traditional medicine, contributing to economic value. However, research on its phytochemical composition and health benefits is limited, highlighting the need for further investigation. Objectives: The current study assessed morphological traits, biochemical composition, and antioxidant activity using the 2,2-diphényl-1-picrylhydrazyl (DPPH) assay. Methods: The morphological traits, biochemical parameters, and antioxidant content of the Moroccan O.dilleniifruit fractions, namely peel, juicy pulp, and seeds, were investigated. Results: The coefficient of variation of the morphological traits oscillated between 16.03 % for fruit weight and 51.83 % for seed weight, indicating a broad level of morphological variability. The total phenolic content of fruit fractions ranged from 202 to 56 g EAG/ 100 g extract, while the total flavonoids varied from 185 to 11 mg EC/100g extract. In addition, the total levels of betacyanins, betaxanthins, and condensed tannins ranged from 6.1 to 335 mg/L, 4.7 to 123 mg/L, and 12 to 8.3 mg/100g, respectively. As for ascorbic acid, it was concentrated in the juicy pulp at 580 mg/100 g, while it was absent in the seeds fraction. The phenolic compounds, flavonoids, and betalain contents were significantly correlated with antioxidant activities, whereas total ascorbic acid and condensed tannins were weakly correlated. Conclusion: These findings suggest that O. dillenii fruits may be a potential source of natural antioxidants for both food applications and medicinal functions.

La actividad física y el control emocional en la salud del profesional de enfermería

Las actividades que realiza el profesional de la enfermería les producen quebranto en la salud, siendo el estrés el primer factor que va a afectar el ritmo propio, ocasionando irritabilidad y ansiedad. La práctica físico-deportiva tiene un efecto positivo sobre su salud física y mental debido a que produce liberación de endorfinas, lo que conlleva una reducción de la ansiedad, la depresión y el estrés, ya que cualquier tipo de actividad física, ya sea de bajo o alto impacto, libera estas sustancias que actúan directamente sobre el cerebro, produciendo sensación de bienestar y relajación inmediata. Se presenta una investigación con un diseño no experimental, desde el enfoque cuantitativo de tipo descriptivo comparativo de corte transversal. Tiene como objetivo: determinar las relaciones entre actividad física y regulación emocional de un grupo de enfermeras (o) s del Hospital Sur en Chilpancingo, Guerrero, México. Se aplicó la Escala para Evaluación de la Inteligencia Emocional TMMS-24 y el Cuestionario Internacional de Actividad Física (IPAQ). Para determinar la relación entre las variables se empleó la Correlación del Rho de Spearman. Las dimensiones estudiadas son la atención, claridad y reparación emocional por parte de la variable dependiente (Control emocional) y las dimensiones Alta, Media y Baja por la variable independiente (Actividad física). En la comunidad donde se observaron los signos y síntomas de nerviosismo, agitación o tensión asociados a situaciones de ansiedad y estrés, se establecen correlaciones directas entre la intensidad de la actividad física y el control emocional de los sujetos investigados, o sea, a menor intensidad de la actividad física menor control y regulación emocional.

As atividades realizadas pelo profissional de enfermagem causam-lhe problemas de saúde, sendo o estresse o primeiro fator que afetará seu próprio ritmo, causando irritabilidade e ansiedade. A prática físico-esportiva tem um efeito positivo sobre sua saúde física e mental, pois produz uma liberação de endorfinas, o que leva a uma redução da ansiedade, da depressão e do estresse, pois qualquer tipo de atividade física, seja ela de baixo ou alto impacto, libera essas substâncias que atuam diretamente no cérebro, produzindo uma sensação de bem-estar e relaxamento imediato. A pesquisa é apresentada em um desenho não-experimental, a partir de uma abordagem quantitativa, descritiva, comparativa, transversal e de corte transversal. Seu objetivo é determinar a relação entre a atividade física e a regulação emocional em um grupo de enfermeiras do Hospital Sur em Chilpancingo, Guerrero, México. Foram aplicados o Emotional Intelligence Rating Scale TMMS-24 e o International Physical Activity Questionnaire (IPAQ). A Correlação Rho de Spearman foi usada para determinar a relação entre as variáveis. As dimensões estudadas são Atenção, Clareza e Reparação Emocional para a variável dependente (Controle Emocional) e as dimensões Alta, Média e Baixa para a variável independente (Atividade Física). Na comunidade onde foram observados os sinais e sintomas de nervosismo, agitação ou tensão associados a situações de ansiedade e estresse, foram estabelecidas correlações diretas entre a intensidade da atividade física e o controle emocional dos sujeitos investigados, ou seja, quanto menor a intensidade da atividade física, menor o controle e a regulação emocional.

The activities carried out by the nursing professional produce them health problems, with stress being the first factor that will affect one's own rhythm, causing irritability and anxiety. Physical-sports practice has a positive effect on their physical and mental health because it produces the release of endorphins, which leads to a reduction in anxiety, depression and stress because any type of physical activity, whether low or high impact, releases these substances that act directly on the brain, producing a feeling of well-being and immediate relaxation. A research is presented with a non-experimental design, from the quantitative approach of a cross-sectional comparative descriptive type. Its objective is to determine the relationships between physical activity and emotional regulation of a group of nurses from the Sur Hospital in Chilpancingo, Guerrero, Mexico. The TMMS-24 Emotional Intelligence Assessment Scale and the International Physical Activity Questionnaire (IPAQ) were applied. To determine the relationship between the variables, Spearman's Rho Correlation was used. The dimensions studied are attention, clarity and emotional repair by the dependent variable (Emotional Control) and the High, Medium and Low dimensions by the independent variable (Physical Activity). In the community where the signs and symptoms of nervousness, agitation or tension associated with situations of anxiety and stress were observed, direct correlations were established between the intensity of physical activity and the emotional control of the subjects studied, that is, at a lower intensity of physical activity, less control and emotional regulation.

La danza afroecuatoriana: alternativa metodológica para la inclusión de estudiantes con hiperactividad en la Educación Física

Se reconoce que la danza afroecuatoriana es un lazo de conexión con los ancestros y la identidad, y aporta una educación del movimiento que facilita, a su vez, el desarrollo de valores educativos en torno al tratamiento del cuerpo; ello favorece la motivación hacia la práctica de la actividad física continuada. El objetivo de la investigación radica en proponer la danza afroecuatoriana como una alternativa metodológica para la inclusión de estudiantes con hiperactividad y se contextualiza en décimo año, con un total de 35 estudiantes, y una muestra de un estudiante con trastorno por déficit de atención e hiperactividad, de la Básica Superior de la Unidad Educativa "José Otilio Ramírez Reina", provincia de Esmeraldas en Ecuador. El estudio, se sustentó en un enfoque cuantitativo-cualitativo y el método dialectico-materialista; se emplearon métodos del nivel teórico como el histórico-lógico y el análisis-síntesis y del nivel empírico el análisis documental, la observación y la encuesta, para interpretar las derivaciones obtenidas en cada etapa que transitó desde el nivel exploratorio, descriptivo, hasta llegar a una explicación del fenómeno investigado.

Del estudio realizado se concluyó que la danza afroecuatoriana constituye una vía expedita para un mejor conocimiento, disfrute y preservación de la identidad, en estos estudiantes.

Reconhece-se que a dança afro-equatoriana é um vínculo de ligação com os ancestrais e a identidade, e proporciona uma educação em movimento que facilita, por sua vez, o desenvolvimento de valores educativos em torno do tratamento do corpo; Isso favorece a motivação para a prática de atividade física continuada. O objetivo da pesquisa consiste em propor a dança afro-equatoriana como alternativa metodológica para a inclusão de alunos com hiperatividade e está contextualizada no décimo ano, com um total de 35 alunos, e uma amostra de um aluno com transtorno de déficit de atenção e hiperatividade, da Escola Básica Superior da Unidade Educacional "José Otilio Ramírez Reina", província de Esmeraldas no Equador. O estudo baseou-se na abordagem quanti-qualitativa e no método dialético-materialista; Métodos do nível teórico como histórico-lógico e análise-síntese e do nível empírico, análise documental, observação e levantamento, foram utilizados para interpretar as derivações obtidas em cada etapa que passou do nível exploratório, descritivo, até chegar a uma explicação do fenômeno investigado. Os resultados revelam o insuficiente reconhecimento da dança afro-equatoriana para a inclusão de alunos com esse transtorno, bem como a limitada produção científica relacionada ao tema. Do estudo realizado concluiu-se que a dança afro-equatoriana constitui um caminho expedito para um melhor conhecimento, diversão e preservação da identidade destes alunos.

Afro-Ecuadorian dance is a bond of connection with ancestors and identity, and provides an education in movement that facilitates, in turn, the development of educational values around the treatment of the body; this favors motivation towards the practice of continued physical activity. The objective of the research lies in proposing Afro-Ecuadorian dance as a methodological alternative for the inclusion of students with hyperactivity and is contextualized in the tenth grade, with a total of 35 students, and a sample of a student with attention deficit hyperactivity disorder, from the Higher Basic School "José Otilio Ramírez Reina" Educational Unit, province of Esmeraldas in Ecuador. The study was based on a quantitative-qualitative approach and the dialectical-materialist method; methods from the theoretical level such as historical-logical and analysis-synthesis and from the empirical level, documentary analysis, observation and survey, were used to interpret the derivations obtained in each stage that went from the exploratory, descriptive level, until reaching an explanation of the phenomenon investigated. The results reveal the insufficient recognition of Afro-Ecuadorian dance for the inclusion of students with this disorder, as well as the limited scientific production related to the topic. From the study carried out, it was concluded that Afro-Ecuadorian dance constitutes an expeditious route for better knowledge, enjoyment and preservation of identity in these students.

Productividad académica y su relación con la actividad física y la satisfacción con el trabajo / Productividad académica, actividad física y satisfacción laboral

Resumen Objetivo: Determinar si la productividad académica se relaciona con la actividad física y la satisfacción con el trabajo en académicos de una universidad pública de México. Materiales y métodos: Estudio cuantitativo de tipo transversal analítico correlacional, la muestra fueron 215 académicos inscritos en la Universidad Veracruzana del estado de Veracruz, México, el muestreo fue no probabilístico por cuotas. Se aplicó la escala tipo Likert de Satisfacción en el Trabajo que consta de 8 ítems, y el Cuestionario Internacional de Actividad Física (IPAQ) versión corta compuesto por 7 ítems los cuales brindan información respecto al tiempo dedicado a realizar actividad física (sedentarismo, intensidad ligera, intensidad moderada y vigorosa), así como, preguntas socio demográficas y laborales. El análisis fue mediante estadística descriptiva e inferencial, a través del software IBM SPSS Statistics 26 for Mac. Resultados: Participaron 263 académicos, la mayoría (68.1%) reportó un nivel medio de satisfacción en el trabajo; 41.4% reportó actividad física sedentaria. Quienes se encuentran en niveles altos de productividad académica reportaron caminar menos días a la semana en comparación con los que están en niveles inferiores. La antigüedad laboral se relacionó positivamente con los días que caminan tanto en el grupo sedentario como en los activos, pero la fuerza de esta asociación fue mucho mayor en los sedentarios (r = 366) que en los activos (r = 186). Conclusiones: No se encontró relación entre los niveles mayores de productividad y mayor satisfacción con el trabajo o, con mayor realización de actividad física, por lo que se rechazan las hipótesis. Pero se muestra que las características laborales como la jornada y la antigüedad laboral limitan la realización de actividades físicas sobre todo en el 41.4% de la población que se clasificó como población sedentaria, generando sin duda algún riesgo para su salud por la falta de actividad física.

Abstract Objective: We aimed to determine whether academic productivity is related to physical activity and job satisfaction among the academic staff working for a public university located in Mexico. Materials and methods: A quantitative, cross-sectional, analytical and correlational study was carried out., the sample of 215 academics enrolled at Universidad Veracruzana, located in Veracruz, Mexico, non-probability quota sampling. We used both the 8-item Job Satisfaction Likert-type scale, and the 7-item International Physical Activity Questionnaire (IPAQ), short version, which provides information regarding the time spent doing physical activity (sedentary, light intensity, moderate intensity and vigorous), as well as socio-demographic and work-related items. The analysis was done using descriptive and inferential statistics with the IBM SPSS Statistics 26 software for Mac. Results: 263 academics were involved, the majority (68.1%), reported a medium level of job satisfaction, 41.4% reported sedentary physical activity. Those with high levels of academic productivity reported walking fewer days per week compared to those with lower levels. Job seniority was positively related to days walked for both the sedentary and active groups, but the strength of this association was much higher for the sedentary (r = 366) groups than the active (r = 186) groups. Conclusions: No relationship was found between higher levels of productivity and higher job satisfaction or higher physical activity, so the hypotheses are rejected. But it is shown that job characteristics such as work hours and job seniority, limit physical activity, especially for the 41.4% of the population classified as a sedentary population, posing some health risks because of the lack of physical activity.

Asociación entre la movilidad articular, composición corporal y actividad física autopercibida en universitarios de Bogotá, Colombia. 2023 / Association between joint mobility, body composition, and self-reported physical activity in university students from Bogotá, Colombia. 2023

Resumen Introducción: La movilidad articular es una cualidad física que disminuye con el avance de la edad si no se entrena de manera sistemática. Desempeña un papel crucial en la realización eficiente de las actividades cotidianas, desde acciones sencillas como caminar hasta movimientos más complejos como realizar actividad física. Objetivo: Analizar la relación entre los niveles de movilidad articular, la composición corporal y la actividad física autopercibida en estudiantes universitarios. Metodología: Diseño transversal con un enfoque descriptivo-correlacional, y se implementó un muestreo por conveniencia. Para evaluar la movilidad articular se utilizó la batería de pruebas flexitest, la composición corporal se evaluó a través de bioimpedancia tetrapolar y se registró la actividad física autopercibida mediante la "escala subjetiva de actividad física". Resultados: Participaron en el estudio 72 sujetos universitarios con una edad promedio de 22,4 ± 3,74 años. Se encontró que las mujeres presentan niveles de movilidad articular superiores a los hombres, 55,50 puntos vs. 48,92, respectivamente (p = 0,003). Además, se observó una mayor frecuencia en la categoría "alta" en el nivel de movilidad articular en los participantes (45,2 %). No se encontró una asociación significativa entre los niveles de movilidad articular, la composición corporal y la actividad física (p > 0,05). Más del 56 % de los participantes no cumplen con las recomendaciones mínimas de actividad física a la semana recomendadas. Conclusiones: Los niveles de movilidad articular y composición corporal varía según el sexo, se deben diseñar estrategias institucionales para la promoción de la actividad física.

Abstract Introduction: Joint mobility is a physical quality that decreases with age if not systematically trained. It plays a crucial role in the efficient performance of everyday activities, from simple actions such as walking to more complex movements such as lifting or physical activity. Objective: to analyze the relationship between levels of joint mobility, body composition, and self-perceived physical activity in university students. Methods: A cross-sectional design with a descriptive-correlational approach, and convenience sampling was implemented. Joint mobility was assessed using the Flexitest test battery, body composition was evaluated through tetrapolar bioimpedance, and self-perceived physical activity was recorded using the "subjective physical activity scale". Results: The study included 72 university subjects with an average age of 22,4 ± 3,74 years. It was found that women have higher levels of joint mobility compared to men, 55,50 points vs. 48,92, respectively (p = 0,003). Additionally, a higher frequency was observed in the "high" category of joint mobility level among the participants (45,2 %). No significant association was found between levels of joint mobility, body composition, and physical activity (p > 0,05). More than 56 % of the participants do not meet the recommended minimum weekly physical activity guidelines. Conclusions: Levels of joint mobility and body composition vary according to sex, institutional strategies should be designed to promote physical activity.

Eye Bird View on Natural Plants in the Management of Mucormycosis

Mucormycosis, also referred to as Zygomycosis, is chiefly caused by filamentous molds belonging to the Mucorales group. It can be acquired through inhaling spores, consuming contaminated food, or through injury to the skin. Currently, the second most prevalent fungal infection disease is mucormycosis. It gained greatest attention following the COVID-19 pandemic. The review mainly focuses on several outlines like its history, epidemiology, pathophysiology, types, diagnosis and treatment of mucormycosis. In treatment of mucormycosis, conventional therapy against mucormycosis and some antifungal agents has been discussed. Several diverse contagious ailments were conventionally cured utilizing a widespread series of medicinal plants. Given that India is at the forefront of the Ayurvedic and Siddha medical systems, traditional herbal medicine from India is highly well-known. Antifungal chemicals derived from plants can be a viable option for developing novel and enhanced alternative formulations in the field of antifungal medicine. The main focus of the review is to explore the potential plants having the antifungal activity used for the treatment of mucormycosis. Some of the plants with antifungal activity have been explained, which includes garlic, tea tree oil, aloe vera, thyme, turmeric, neem, eucalyptus, clove, goldenseal, calendula, lavender, guduchi, and oregano.

Comparative Antioxidant and Phytochemical Evaluation of Selected Varieties of Colocasia esculenta (L.) Schott Leaves

Sree Kiran, Sree Rashmi, Sree Pallavi, and Muktakeshi are the four commonly cultivated varieties of Colocasia esculenta (L.) Schott. The current study aims to perform phytochemical screening and the antioxidant capacity of the leaf extracts of these varieties. Furthermore, LCMS was used to examine the polyphenolic content of Muktakeshi's ethanolic leaf extract. The phytochemical analysis of the cultivars indicated that all extracts contained beneficial phytocompounds like phenols, terpenoids, flavonoids, alkaloids, saponins, and tannins. The ethanolic leaf extract of Muktakeshi was found to have greater levels of total phenol (39.47±0.47 GAE mg/g) and flavonoid (49.672±0.15 QE mg/g) contents. All the leaf extracts exhibited a moderate antioxidant ability, whereas the ethanolic extract of Muktakeshi exhibited comparatively higher antioxidant potential in both DPPH (88.3±0.58%) and nitric oxide (84.6±0.79%) assays with the least IC50 value. The LCMS studies detected eight polyphenolic compounds like quercetin, kaempferol, gallic acid, caffeic acid, luteolin 7-rutinoside, chlorogenic acid, vitexin, and rutin in the ethanolic leaf extract of Muktakeshi. It is a good source of many potentially effective bioactive compounds and helps to prevent human oxidative stress-associated diseases. The present study found considerable variations in the phenol-flavonoid content and antioxidant properties of the Colocasia varieties studied.

Screening of herbal extracts for rapid effect on activity-induced knee joint discomfort: a randomized and placebo-controlled

Background:A feasibility study was conducted to investigate the effect of different proprietary extracts on joint discomfort associated with repeated episodes of physical activity.Methods:A single-dose randomized, double-blind, placebo-controlled cross-over study was conducted in three phases with different extract combinations. Seventeen individuals aged 40-60 years with a history of knee joint pain aggravation on physical stress were randomized to receive the investigational product or the placebo in a 1:1 ratio. The primary outcome was the time taken to achieve meaningful pain relief (MPR) from baseline using a pain visual analog scale (VAS) compared to the placebo. The secondary outcomes were the pain intensity difference (PID) and joint discomfort at 1-, 2-, 3-, and 4-hours post-product administration and the time-weighted sum of pain intensity difference (SPID) over 4 hours compared to placebo.Results:Participants in two out of eight investigational product groups achieved MPR successfully. The proprietary combination ZV-E (consisting of Z. officinaleand V. negundo) showed the fastest pain reduction with more than 50% of the participants achieving meaningful relief. The BS-ZP (consisting of B. serrata+ Z. officinale+ P. lanceolata) group also had more than 50% of participants reporting MPR at 4 hours post-IP administration. Subsequently, the SPID was found to be lowest in the participants of above stated groups.Conclusions:The proprietary combination of Z. officinaleand V. negundoextracts, 200 mg could be a promising lead to conduct a further trial to investigate its effect on joint pain.

Changes in biomarkers of lipid in juvenile idiopathic arthritis and its association with various disease parameters: a 6-month follow-up study

Background: The objectives of our study were to determine the changes in lipid profile (total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)) in juvenile idiopathic arthritis (JIA) and assess its association with epidemiological and clinical profile of JIA patients.Methods: This observational study was performed with 46 patients at presentation followed by 38 cases at 3 months and 18 cases at 6 months of follow up. Their demographic profile and clinical parameters including juvenile disease activity score (JADAS 27) were compared with the biomarkers of lipid profile.Results: The mean (SD) age was 105.85 (20.23) months at first visit with mean (SD) disease duration being 15 (6.4) months. Twenty-six participants had oligoarthritic (56.5%), while the rest had polyarthritis (43.4%). Most of the patients had borderline raised TG and LDL-C (cases with raised TG n=14 (30.4%), 12 (31.5%), 5 (27.7%) at 1st visit, 3 months, and 6 months respectively and LDL-C n=12 (26%), 10 (26.3%), 6 (33.3%) at 1stvisit, 3 months, and 6 months respectively). HDL-C level was low in 36 (78.2%) cases at first visit, 28 cases (73.6%) at 3 months and 12 cases (66.6%) at 6 months respectively. Lipid profile was significantly affected by gender difference, duration of disease and drug therapy (p<0.05). Significant association have been found between JADAS score and TGL level with p value 0.03.Conclusions: Children with JIA definitely suffer from dyslipidemia. Among the biomarkers of lipid profile, low level of HDL-C is one of the most important highlights of our study. Further studies can help to strengthen the findings and formulate necessary interventions at an early stage.

Physical activity levels and junk food intake among female undergraduate students in Mandya: a cross sectional study

Background: Physical activity (PA) is defined as any bodily movement produced by skeletal muscles that requires energy expenditure. It has been proven that regular physical activity helps control and prevent noncommunicable diseases like diabetes, heart disease, stroke, and several types of cancer. This study aimed to describe the levels of physical activity among female undergraduate students in Mandya and to assess their knowledge, attitude and practice regarding junk food habits. Methods: This cross-sectional study was done in Government women’s degree college, Mandya district, South Karnataka between November 2023 to December 2023 among female undergraduate students in the institute. Global physical activity questionnaire (GPAQ) has been used to describe their physical activity levels. Descriptive statistics like frequency, proportion, mean and standard deviation has been used. Results: The study was conducted among 170 students. Based on the MET values it is found that majority of them had moderate level of PA 81 (47.6%), while 39(22.9%) had high levels and 50 (29.4%) had low PA levels. Of 170 participants, 43 (25%) had junk food intake once a week, 46 (27%) had twice a week, 81 (48%) had thrice or more per week. The association between PA level and junk food was found to be statistically significant (p<0.05). Conclusions: The findings of this study help us in understanding the importance of adopting a healthy lifestyle, including a balanced diet and regular physical activity practice.
