ABSTRACT

SUMMARY: This review article will present an overview of biological profiles in forensic utilities. The biological profile of the skull in the existing literature can help to identify humans, especially if the condition of the victim found is a result of mutilation or a bomb explosion. When it comes to the precision of identifying skeletal remains, the human skull is frequently cited as being first in the estimation of age and ancestry and second in terms of sex and stature. It can be an alternative to assessing the following biological parameters: sex, age, stature, and ancestry. The implementation of biological profiles in the identification process is very important considering that some cases require the assistance of forensic anthropology. This review article shows the importance of the value of skulls. The method that can be applied is craniometry which can be used to determine sex, age, stature, and estimated ancestry. Different results will occur depending on the completeness of the skull. Therefore, estimation formulas have different accurate results. Discriminant function analysis has been performed on various measurement sets and its discriminant power has been validated by many researchers. Geometric morphometric analysis has become the main tool for shape analysis and many attempts have been made to use it in analyzing skulls. Several methods supported by technology have also been developed. It is hoped that the review article will show significant differences in results between studies in Thailand and Indonesia, even though they are in the same racial group.


Este artículo presenta una descripción general de los perfiles biológicos en las utilidades forenses. El perfil biológico del cráneo en la literatura existente puede ayudar a identificar a los humanos, especialmente si la condición en la que se encuentra la víctima es el resultado de una mutilación o la explosión de una bomba. Cuando se trata de la precisión en la identificación de restos óseos, el cráneo humano se cita con frecuencia como el primero en la estimación de edad y ascendencia y el segundo en términos de sexo y estatura. Puede ser una alternativa para evaluar los siguientes parámetros biológicos: sexo, edad, estatura y ascendencia. La implementación de perfiles biológicos en el proceso de identificación es importante considerando que algunos casos requieren la asistencia de la antropología forense. Este artículo de revisión muestra la importancia del valor de las cnezas óseas. El método que se puede aplicar es la craneometría para determinar el sexo, la edad, la estatura y la ascendencia estimada. Se pueden obtener diferentes resultados dependiendo de la integridad del cráneo. Por lo tanto, las fórmulas de estimación tienen resultados precisos diferentes. Se ha realizado un análisis de función discriminante en varios conjuntos de medidas y muchos investigadores han validado su poder discriminante. El análisis a través de la morfometría geométrica se ha convertido en la principal herramienta para el análisis de formas y se ha utilizado frecuentemente en el análisis de cráneos. También se han desarrollado varios métodos apoyados en la tecnología. Se espera que este trabajo muestre diferencias significativas en los resultados entre los estudios realizados en Tailandia e Indonesia, aunque pertenezcan al mismo grupo racial.

ABSTRACT

SUMMARY: The handgrip strength is used as a means of individual's health prediction during life. It is used as an indicator of the nutrition status, bone fragility, presence of sarcopenia and it correlates with certain diseases and clinical complications. The research goal was to analyze the results of the hand dynamometry test, based on the chronological and biological age, and to offer normative and referent standards about children and adolescents from the Republic of North Macedonia. The study was conducted on a sample of 4031 respondents of both sexes at the age 6-14 years. In order to achieve the research goals, the measured characteristics were of the weight, height, sitting height and handgrip strength. The body mass index and biological maturity values (APHV) were obtained by using formulas. On the basis of the obtained results, it can be concluded that statistically significant differences in handgrip strength are established between the boys and girls of all age categories. Also, statistically significant differences between boys and girls are established in the hand dynamometry test of all APHV levels. In general, the use of the APHV allows a better categorization of the performance of the studied children and adolescents. With boys, the correlation between the chronological age and test was 68 %, and with girls - 77 %. The normative referent standards of the hand dynamometry test are presented in percentiles for both sexes. Thye hand dynamometry test's results during childhood and adolescence should be analyzed and interpret on the basis of biological age, and not on the chronological age. These tools can help specialists who work with children and adolescents in ethnic and epidemiological context.


La fuerza de prensión se utiliza como medio para predecir la salud del individuo durante la vida. Se utiliza como indicador del estado nutricional, fragilidad ósea, presencia de sarcopenia y se correlaciona con determinadas enfermedades y complicaciones clínicas. El objetivo de la investigación fue analizar los resultados de la prueba de dinamometría manual, con base en la edad cronológica y biológica, y ofrecer estándares normativos y referentes sobre niños y adolescentes de la República de Macedonia del Norte. El estudio se realizó en una muestra de 4031 encuestados de ambos sexos con edades comprendidas entre 6 y 14 años. Para lograr los objetivos de la investigación, las características medidas fueron el peso, la altura, la altura al sentarse y la fuerza de prensión. El índice de masa corporal y los valores de madurez biológica (APHV) se obtuvieron mediante fórmulas. Sobre la base de los resultados obtenidos, se puede concluir que se establecen diferencias estadísticamente significativas en la fuerza de prensión manual entre niños y niñas de todas las categorías de edad. Asimismo, se establecen diferencias estadísticamente significativas entre niños y niñas en la prueba de dinamometría manual de todos los niveles APHV. En general, el uso del APHV permite una mejor categorización del desempeño de los niños y adolescentes estudiados. En los niños, la correlación entre la edad cronológica y la prueba fue del 68 %, y en las niñas, del 77 %. Los estándares normativos referentes de la prueba de dinamometría manual se presentan en percentiles para ambos sexos. Los resultados de la prueba de dinamometría manual durante la infancia y la adolescencia deben analizarse e interpretarse en función de la edad biológica y no de la edad cronológica. Estas herramientas pueden ayudar a los especialistas que trabajan con niños y adolescentes en un contexto étnico y epidemiológico.

ABSTRACT

Abstract In order to better understand the ossification processes in anurans our study was carried out on tadpoles and adults of Lithobates catesbeianus. In this sense, we characterized the kinetic properties of alkaline phosphatase with p-nitrophenylphosphatase (pNPP) and pyrophosphate (PPi) and evaluated the activities of tartrate-resistant acid phosphatase and acid phosphatase. The enzyme extracts were obtained from tadpoles and adult femurs, which were divided into epiphysis and diaphysis. After homogenization, the samples were submitted to differential centrifugation to obtain cell membranes and, further, to phospholipase C (PIPLC) treatment, to remove membrane-bound proteins anchored by phosphatidylinositol. The average of specific activity for pNPP hydrolysis (at pH 10.5) by alkaline phosphatase released by phosphatidylinositol-specific phospholipase C (PIPLC) from Bacillus cereus among different bone regions at different animal ages was 1,142.57 U.mg-1, while for PPi hydrolysis (at pH 8.0), it was 1,433.82 U.mg-1. Among the compounds tested for enzymatic activity, the one that influenced the most was EDTA, with approximately 67% of inhibition for pNPPase activity and 77% for PPase activity. In the case of kinetic parameters, the enzyme showed a "Michaelian" behavior for pNPP and PPi hydrolysis. The Km value was around 0.6mM for pNPPase activity and ranged from 0.01 to 0.11mM for PPase activity, indicating that the enzyme has a higher affinity for this substrate. The study of pNPP and PPi hydrolysis by the enzyme revealed that the optimum pH of actuation for pNPP was 10.5, while for PPi, which is considered the true substrate of alkaline phosphatase, was 8.0, close to the physiological value. The results show that regardless of the ossification type that occurs, the same enzyme or isoenzymes act on the different bone regions and different life stages of anurans. The similarity of the results of studies with other vertebrates shows that anurans can be considered excellent animal models for the study of biological calcification.


Resumo Para melhor compreender o processo de ossificação em anuros, nosso estudo foi conduzido em girinos e adultos de Lithobates catesbeianus. Nesse sentido, as propriedades cinéticas da fosfatase alcalina com p-nitrofenilfosfato (pNPP) e pirofosfato (PPi) foram caracterizadas, e as atividades enzimáticas das fosfatases ácida e ácida tartarato resistente foram avaliadas. Os extratos enzimáticos foram obtidos de fêmur de girinos e adultos, divididos em epífise e diáfise. Após a homogeneização as amostras foram submetidas à centrifugação diferencial para obter membrana celular e, em seguida, ao tratamento com fosfolipase C (PIPLC), para remover as proteínas de membrana ancoradas por fosfatidilinositol. A média da atividade específica da fosfatase alcalina, liberada pela PIPLC de Bacillus cereus, para a hidrólise de pNPP (pH 10,5) nas diferentes regiões do fêmur e idades dos animais foi de 1.142,57 U.mg-1, enquanto para a hidrólise do PPi (pH 8,0) foi de 1.433,82 U.mg-1. Entre os compostos testados para a atividade enzimática, o de maior influência foi o EDTA, inibindo aproximadamente 67% e 77% das atividades de pNPPase e PPase, respectivamente. Quanto aos parâmetros cinéticos, a enzima apresentou comportamento Michaeliano para a hidrólise dos dois substratos. O valor de Km foi de 0,6 mM para a atividade de pNPPase e variou de 0,01 a 0,11 para a atividade de PPase, indicando uma maior afinidade por esse substrato. O estudo da hidrólise de pNPP e PPi revelou que o pH ótimo aparente de atuação foi de 10,5 para o pNPP e 8,0 para o PPi, próximo ao fisiológico, sendo que esse é considerado o substrato natural da fosfatase alcalina. Os resultados demonstram que, apesar do tipo de ossificação que ocorre, a mesma enzima ou isoenzimas, atuam nos diferentes locais do osso e estágios de vida dos anuros. A similaridade dos estudos com os realizados com outros vertebrados apontam que os anuros podem ser considerados excelentes modelos animais para o estudo da calcificação biológica.

ABSTRACT

Background: Mammary gland tumors are the most prevalent neoplasm in intact female dogs, and they are good natural models to study comparative oncology. Most canine mammary malignancies, as in women, are commonly refractory to conventional therapies and demand continuous new therapeutic approaches. Crotalus durissus terrificus, also called rattlesnake, has more than 60 different proteins in its venom with multiple pharmaceutical uses, such as antitumor, antiviral, and antimicrobial action. Crotoxin, a potent β-neurotoxin formed by the junction of two subunits, a basic subunit (CB-PLA2) and an acidic subunit (crotapotin), has already been reported to have anticancer properties in different types of cancers. Methods: In this work, we describe the cytotoxic potential of crotoxin and its subunits compared to doxorubicin (drug of choice) in two canine mammary carcinoma cell lines. Results: Crotoxin, CB-PLA2, crotalic venom, and doxorubicin decreased cell viability and the ability to migrate in a dose-dependent manner, and crotapotin did not present an antitumoral effect. For all compounds, the predominant cell death mechanism was apoptosis. In addition, crotoxin did not show toxicity in normal canine mammary gland cells. Conclusion: Therefore, this work showed that crotoxin and CB-PLA2 had cytotoxic activity, migration inhibition, and pro-apoptotic potential in canine mammary gland carcinoma cell lines, making their possible use in cancer research.

ABSTRACT

@#The cardiac conduction system (CCS) is a set of specialized myocardial pathways that spontaneously generate and conduct impulses transmitting throughout the heart, and causing the coordinated contractions of all parts of the heart. A comprehensive understanding of the anatomical characteristics of the CCS in the heart is the basis of studying cardiac electrophysiology and treating conduction-related diseases. It is also the key of avoiding damage to the CCS during open heart surgery. How to identify and locate the CCS has always been a hot topic in researches. Here, we review the histological imaging methods of the CCS and the specific molecular markers, as well as the exploration for localization and visualization of the CCS. We especially put emphasis on the clinical application prospects and the future development directions of non-destructive imaging technology and real-time localization methods of the CCS that have emerged in recent years.

ABSTRACT

Sesquiterpenoids are natural compounds composed of 15 carbon atoms, which can be divided into sesquiterpene alcohols, ketones, lactones, aldehydes, and carboxylic acids according to oxygen groups. These compounds are widely distributed in nature, and their physiological activities are diverse. For example, many sesquiterpenes with potential anticancer effects have been found for anti-tumor effects, including cytotoxicity, antioxidant, immune regulation, cell proliferation, and so on. In addition, some sesquiterpenoids have good application prospects in antibacterial, anti-inflammatory, and anti-cardiovascular diseases. Malignant tumors, inflammation, bacterial diseases, and cardiovascular diseases are the main diseases that cause human death, and natural products have unique advantages in the treatment of these diseases. Therefore, the development of new drugs that are easy to promote has become a new research hotspot. In this paper, the sesquiterpenes extracted from the natural components of Chinese herbs and plants with anti-tumor, anti-inflammatory, antibacterial, and anti-cardiovascular activities, such as Xanthium, Atractylodes, Convolvulus, Acanthium, Ligularia, Artemisia, Ligularia, Ligularia, Labiaceae Mint, Acanthophyllum, Turmeria, Ginger, and other Chinese herbs and plants, were discussed. The biological activities and related mechanisms of this compound were reviewed, which provided a reference for further research and clinical application of sesquiterpenes.

ABSTRACT

@#Objective To develop and verify a rapid detection method for the biological activity of adalimumab based on U937-NF-κB-Luc cell line. Methods Using U937-NF-κB-Luc cell line as the detection cells,a method for detecting the biological activity of adalimumab was developed based on luciferase luminescence principle. The method was optimized for the concentration of tumor necrosis factor-α(TNF-α)(160 ng/mL as initial concentration,2 times serial dilution,10dilutions),the initial concentration of antibody(2 000 ng/mL,2 times serial dilution,20 dilutions),the dilution multiple of antibody(1. 5,2,3,4 times),the inoculation amount(8 × 103,2 × 104,4 × 104,6 × 104cells/well)and the incubation time(0. 5,1,2,3 h),and verified for the specificity,accuracy,precision and linear range. The relative potency of five batches of adalimumab was detected by using the optimized method and TNF-α neutralization activity method based on L929cells respectively. Results The dose-response curve of adalimumab international standard showed a typical S-type,and the data complied with the four-parameter equation y =(A-D)/[1 +(x/C)B]+ D,R2> 0. 99. The optimum concentration of TNF-α was 5 ng/mL,the initial concentration of antibody was 800 ng/mL,the dilution ratio for adalimumab was 1∶2,the inoculation amount was 2 × 104cells/well,and the induction time was 2 h. Three therapeutic monoclonal antibodies of TNF-α target,such as adalimumab,obtained good dose-response curves,while therapeutic monoclonal antibodies of other non-TNF-α targets did not show this curve. The linear regression equation of the logarithmic value of theoretical potency and the logarithmic value of the corresponding measured potency had a slope of 1. 037,and the relative bias was within the range of ± 12%. The geometric coefficient of variation(GCV)of the relative titer measured value of each sample was less than20%. The theoretical potency ranged from 64% to 156%,showing a good linear relationship with the measured values,and the fitting linear regression equation was y = 1. 037 4 x-0. 023 7,R2= 0. 998 4. There was no significant difference in the relative potency measured results of five batches of adalimumab by the two methods(t = 1. 198,P = 0. 265 1). Conclusion The developed detection method for adalimumab biological activity based on U937-NF-κB-Luc cell line has good specificity,accuracy and precision with short time consumption(3 h),which can be used as a rapid evaluation method for the biological activity of adalimumab.

ABSTRACT

The heat shock protein 90 (Hsp90) protein family is a cluster of highly conserved molecules that play an important role in maintaining cellular homeostasis. Hsp90 and its co-chaperones regulate a variety of pathways and cellular functions, such as cell growth, cell cycle control and apoptosis. Hsp90 is closely associated with the occurrence and development of tumors and other diseases, making it an attractive target for cancer therapeutics. Inhibition of Hsp90 expression can affect multiple oncogenic pathways simultaneously. Most Hsp90 small molecule inhibitors are in clinical trials due to their low efficacy, toxicity or drug resistance, but they have obvious synergistic anti-tumor effect when used with histone deacetylase (HDAC) inhibitors, tubulin inhibitors or topoisomerase II (Topo II) inhibitors. To address this issue, the design of Hsp90 dual-target inhibitors can improve efficacy and reduce drug resistance, making it an effective tumor treatment strategy. In this paper, the domain and biological function of Hsp90 are briefly introduced, and the design, discovery and structure-activity relationship of Hsp90 dual inhibitors are discussed, in order to provide reference for the discovery of novel Hsp90 dual inhibitors and clinical drug research from the perspective of medicinal chemistry.

Las quemaduras son un problema de interés en salud pública ya que generan un alto índice de morbimortalidad a nivel mundial, las quemaduras térmicas son las más prevalentes y pueden alterar la integridad anatómica, funcional y estética de la piel, aspectos fundamentales para la autoestima del paciente y su capacidad para reintegrarse a la sociedad. Al revisar la literatura sobre el tratamiento de estas afecciones encontramos diversos tratamientos, entre ellos el uso de membrana amniótica humana, la cual ha tenido un impacto importante en el manejo de quemaduras al funcionar como andamio biológico con cualidades regenerativas y antiinflamatorias. El presente artículo tiene como objetivo sintetizar la información actual que describe las aplicaciones de membranas amnióticas humanas en quemaduras, realizamos una revisión exploratoria sistemática de la literatura desde 2010 hasta 2021.


Burns are a problem of interest in public health since they generate a high rate of morbidity and mortality worldwide, thermal burns are the most prevalent and can alter the anatomical, functional and aesthetic integrity of the skin, fundamental aspects for the patient's self-esteem and their ability to reintegrate into society. At review literature about the treatment of these conditions, we find various treatments, including the use of human amniotic membrane, which has had a significant impact on burn management by functioning as a biological scaffold with regenerative and anti-inflammatory qualities. The present article aims to synthesize the current information that describes the applications of human amniotic membranes in burns. We carry out a systematic exploratory review of the literature from 2010 to 2021.

ABSTRACT

Los barrenadores del tallo del género de Diatraea spp. (Lepidoptera:Crambidae) han sido reconocidos por ser la plaga de mayor impacto en el cultivo de caña de azúcar, en el que causan importantes pérdidas económicas. Para su control, una cepa colombiana de Beauveria bassiana (Bals.) Vuill (aislamiento Bv062) que demostró alta virulencia frente a larvas de D. saccharalis (Fabricius), fue utilizada para el desarrollo de un bioinsecticida formulado como un concentrado emulsionable (CE). Con el fin de integrar este bioinsecticida en un esquema de manejo integrado de plagas, es necesario evaluar su compatibilidad con los agroquímicos utilizados comúnmente en el cultivo de caña de azúcar. Para tal fin se evaluó el efecto in vitro de 11 agroquímicos (fungicidas, insecticidas y herbicidas) sobre la germinación y actividad insecticida de conidios formulados. Inicialmente el CE y los agroquímicos fueron ajustados al doble de la concentración recomendada y mezclados en proporción 1:1, se incubaron durante dos horas, y se determinó el porcentaje de germinación. Los conidios expuestos a los agroquímicos fueron también purificados y utilizados para un bioen-sayo frente a larvas de segundo instar de D. saccharalis. El CE resultó ser compatible con los herbicidas e insecticidas evaluados, manteniendo una germinación y eficacia superior al 80%. Por el contrario, el CE fue incompatible con todos los fungicidas evaua-dos. Estos resultados permiten sugerir recomendaciones de aplicación del bioplaguicida a base de B. bassiana Bv062, junto con insecticidas y herbicidas empleados en el cultivo de caña, pero se recomienda no aplicarlo de manera simultánea con fungicidas como el benomil y del grupo de triazoles. Se recomienda validar estos resultados en condiciones de campo.


Sugarcane stem borers of the genus Diatraea spp. (Lepidoptera:Crambidae) have been recognized as the pest of the greatest impact on sugarcane crops causing significant economic losses. For its control, a colombian strain of Beauveria bassiana (Bals.) Vuill (code Bv062) that showed a high virulence against D. saccharalis (Fabricius) larvae was used for a biopesticide development, formulated as emulsifiable concentrate (EC). In order to include the EC into an integrated pest management (IPM) scheme, it is necessary to evaluate its compatibility with the agrochemicals commonly used in sugarcane crops. For this purpose, the in vitro effect of 11 agrochemicals (fungicides, insecticides and herbicides) on the germination and insecticidal activity of Bv062 formulated conidia was evaluated. Initially, the EC and agrochemicals were adjusted to double the recommended concentration and mixed in a 1:1 ratio. The mixes were incubated for two hours, and the germination percentage was calculated. The conidia exposed to the agrochemicals were also purified and used for a bioassay against second instar larvae of D. saccharalis. The EC was compatible with the herbicides and insecticides, maintaining germination and efficacy higher than 80%. In contrast, EC was incompatible with all the fungicides evaluated. These results allow us to suggest recommendations for the application of the biopesticide based on B. bassiana Bv062 with insecticides and herbicides used in sugarcane crops, but it is not recommended to apply it simultaneously with fungicides such as benomyl and the triazole group. It is recommended to validate these results under field conditions.

ABSTRACT

En la actualidad uno de los retos a los que se enfrentan los agricultores es producir alimentos bajo las inclemencias climáticas. Para el 2050, se estima un aumento en la demanda en producción de alimentos básicos a causa del incremento demográfico, aumentando con ello el detrimento de los recursos naturales. Dentro de las alternativas biológicas está el uso de insumos a base de microorganismos benéficos, como el género Trichoderma. Los cuales se han utilizado en los campos agrícolas para el control biológico contra un gran número de fitopatógenos. Sin embargo, aún son poco conocidas otras propiedades benéficas de este género para las plantas que coloniza y el ecosistema. Se realizó una búsqueda de artículos científicos en Academic Search Ultimate, BioOne, Acsess, Esmerald, Fuente Académica, ScienceDirect y Springer, entre 2015 y 2023, con dos excepciones de años anteriores. Se utilizó la palabra clave "Trichoderma" y aquellas relacionadas con interacciones microbianas y su aplicación agrícola. Esta revisión resume los hallazgos bibliográficos actuales de este género que muestran su alta capacidad hacia el desarrollo sostenible de los agroecosistemas. Varias investigaciones reportan su capacidad de inducir la defensa vegetal, la promoción del crecimiento y desarrollo radicular, así como la estimulación y síntesis de sustancias que contribuyen a fortalecer la fertilidad del suelo. Con ello mejora los rendimientos de los cultivos a los que se encuentra asociado. En definitiva, la aplicación de Trichoderma puede coadyuvar a disminuir los efectos negativos ocasionados por el uso de agroquímicos y fertilizantes sintéticos, contribuyendo a una producción más sostenible.


Currently, one of the most critical challenges facing farmers is the production of food under adverse weather conditions. By 2050, an increase in the production of staple foods is estimated due to demographics, thereby increasing the depletion of natural resources. Among the biological alternatives is the use of inputs based on beneficial microorganisms such as the Trichoderma genus, which have been used in agricultural fields for biological control against a large number of phytopathogens. However, other beneficial properties of this genus for the plants it colonizes, and the ecosystem are still little known. Therefore, a search for scientific articles was carried out in Academic Search Ultimate, BioOne, Acsess, Esmerald, Fuente Academic, ScienceDirect and Springer, between 2015 and 2023, with two exceptions from previous years. The keyword "Trichoderma" was used and those related to microbial interactions and their agricultural application. Therefore, this review summarizes the current bibliographic findings of this genus, that shows its high capacity towards the sustainable development of agroecosystems. Several investigations report its ability to induce plant defense, promote growth and root development, and stimulate and synthesize substances that help strengthen soil fertility. This improves the yields of the crops to which they are associated. With this, the application of Trichoderma can reduce the negative effects caused by the use of agrochemicals and synthetic fertilizers, contributing to a more sustainable production.

ABSTRACT

ABSTRACT Background: Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a novel inflammatory biomarker which has been associated with cardiovascular diseases. Objective: To study MHR in patients with psoriasis treated with biological agents. Methods: Between April 2019 and August 2022, MHR was retrospectively evaluated in patients with psoriasis before and 3 months after treatment with infliximab, adalimumab, etanercept, ixekizumab, secukinumab, and ustekinumab in a university hospital in Ankara, Turkey. Results: This study included 128 patients, 53 females and 75 males. 39 (30.5%) patients were treated with infliximab, 26 (20.3%) with adalimumab, 8 (6.3%) with etanercept, 18 (14.1%) with ixekizumab, 12 (9.4%) with secukinumab, and 25 (19.5%) with ustekinumab. The median MHR was 0.0127 (0.0086-0.0165) in females and 0.0146 (0.0119-0.0200) in males (p = 0.011). The median MHR decreased after treatment with adalimumab, ixekizumab, secukinumab, and ustekinumab, whereas it increased after treatment with infliximab and etanercept (p = 0.790, p = 0.015, p = 0.754, p = 0.221, p = 0.276, p = 0.889, respectively). Conclusion: MHR significantly decreased in patients with psoriasis after treatment with ixekizumab. Since high MHR levels have been associated with poor clinical outcomes in patients with cardiovascular diseases, ixekizumab might have a positive impact in the treatment of psoriasis patients who had cardiovascular diseases. We suggest that MHR may be useful both in establishing appropriate biological agent treatment and in the follow-up of patients with psoriasis treated with biological agents.

ABSTRACT

Los hongos son organismos polifacéticos presentes en casi todos los ecosistemas de la tierra, donde establecen diversos tipos de simbiosis con otros seres vivos. A pesar de ser reconocidos por los humanos desde la antigüedad -y de la cantidad de trabajos que han profundizado sobre su biología y ecología-, aún falta mucho por conocer sobre estos organismos. Algunos de los criterios que clásicamente se han utilizado para su estudio, hoy resultan limitados y hasta cierto punto permiten un agrupamiento de los aislamientos según algunas características, pero generan confusión en su clasificación y, más aún, cuando se pretende comprender sus relaciones genealógicas. Los caracteres fenotípicos no son suficientes para identificar una especie de hongos y, menos aún, para construir una filogenia amplia o de un grupo particular. Hay grandes vacíos que hacen que los árboles generados sean inestables y fácilmente debatidos. Para los profesionales de la salud, parece que la identificación de los hongos hasta niveles inferiores como género y especie es suficiente para elegir el tratamiento más adecuado para su control, comprender la epidemiología de los cuadros clínicos asociados y reconocer los brotes y los factores determinantes de la resistencia a los antimicrobianos. No obstante, la ubicación taxonómica dentro del reino permitiría establecer relaciones filogenéticas entre los taxones fúngicos, facilitando la comprensión de su biología, su distribución en la naturaleza y la evolución de su potencial patogénico. Los avances de las técnicas de biología molecular y las ciencias de la computación en los últimos 30 años han permitido cambios importantes dirigidos a establecer los criterios para definir una especie fúngica y alcanzar una construcción filogenética más o menos estable. Sin embargo, el camino por recorrer aún es largo, y supone un trabajo mancomunado de la comunidad científica a nivel global y el apoyo a la investigación básica.


Fungi are multifaceted organisms found in almost all ecosystems on Earth, where they establish various types of symbiosis with other living beings. Despite being recognized by humans since ancient times, and the high number of works delving into their biology and ecology, much is still unknown about these organisms. Some criteria classically used for their study are nowadays limited, generating confusion in categorizing them, and even more, when trying to understand their genealogical relationships. To identify species within Fungi, phenotypic characters to date are not sufficient, and to construct a broad phylogeny or a phylogeny of a particular group, there are still gaps affecting the generated trees, making them unstable and easily debated. For health professionals, fungal identification at lower levels such as genus and species, is enough to select the most appropriate therapy for their control, understand the epidemiology of clinical pictures associated, and recognize outbreaks and antimicrobial resistance. However, the taxonomic location within the kingdom, information with apparently little relevance, can allow phylogenetic relationships to be established between fungal taxa, facilitating the understanding of their biology, distribution in nature, and pathogenic potential evolution. Advances in molecular biology and computer science techniques from the last 30 years have led to crucial changes aiming to establish the criteria to define a fungal species, allowing us to reach a kind of stable phylogenetic construction. However, there is still a long way to go, and it requires the joint work of the scientific community at a global level and support for basic research.

ABSTRACT

Resumen Este ensayo cuestiona a la medicina evolutiva o darwiniana por su adhesión acrítica a la teoría evolucionista para explicar las enfermedades, que deja de lado el propio proceso vital que transformó un planeta "inerte" en uno "viviente", donde el orden biológico naciente subordinó al fisicoquímico imperante para prevalecer. El orden biológico es equiparable a un "concierto armónico infinitamente diverso", que ha creado y recreado, por eones, los ambientes propicios para su propia permanencia y evolución. El arribo del homo sapiens significó el surgimiento del orden cultural que suplantó progresivamente en sus efectos, al orden biológico, al provocar cambios drásticos y vertiginosos en el ecosistema planetario que silenciaron el proceso evolutivo "sin tiempo para manifestarse". La adaptación como aptitud para sobreponerse a situaciones adversas, es un contrasentido en el "concierto armónico"; en cambio, es característica del orden cultural que impone a los humanos ambientes inhóspitos y estresantes como exigencias adaptativas ineludibles. La cualidad vital propia del orden biológico es la anticipación secuencial de las situaciones de interacción con los objetos significativos del ambiente, que posibilita la consumación de las actividades vitales básicas, emblema del estado de madurez de los seres vivos. Pensar que la evolución explica las enfermedades crónicas no solo es ilusorio, sino contraproducente, porque encubre la raíz de nuestros problemas: una humanidad en constante disarmonía entre etnocentrismos belicosos, perpetradora de la devastación planetaria, cuyo valor supremo es el lucro sin límites.


Abstract This essay questions evolutionary or Darwinian medicine for its uncritical adherence to evolutionary theory to explain diseases, which leaves aside the very vital process that transformed an "inert planet" into a "living one" where the nascent biological order subordinated the physicochemical one to prevail. The biological order is comparable to an "infinitely diverse harmonic concert", which has created and recreated, for eons, the environments conducive to its own permanence and evolution. The arrival of homo sapiens meant the cultural order emergence, which progressively supplanted, in its effects, the biological order by causing drastic and vertiginous changes in the planetary ecosystem that silenced the evolutionary process "without time to manifest". Adaptation as an ability to overcome adverse situations is a non-sense in the "harmonic concert"; instead, it is characteristic of the cultural order that imposes inhospitable and stressful environments on humans as inescapable adaptive demands. The vital quality of the biological order is the sequential anticipation of situations of interaction with significant objects in the environment, which enables the consummation of basic vital activities, emblematic of the state of maturity of living beings. To think that evolution explains chronic diseases is not only illusory but counterproductive because it covers up the root of our problems: a humanity in constant disharmony between bellicose ethnocentrisms, perpetrator of planetary devastation, whose supreme value is profit without limits.
