El desentrenamiento deportivo en el boxeo

La preparación del boxeador conlleva cambios y adaptaciones fisiológicas para garantizar las cargas físicas, psíquicas y sociales a las que han sido sometidos sus practicantes. Finalizada dicha etapa aparece el desentrenamiento deportivo, cuya naturaleza es eminentemente pedagógica y consiste en desinstalar los componentes que garantizaron la acumulación de cargas durante su etapa como boxeador activo, hasta alcanzar los niveles de un practicante sistemático normal de la Cultura Física. El objetivo de este trabajo consistió en diseñar una estrategia pedagógica sustentada en un modelo de igual naturaleza para el desentrenamiento potenciado con la equino-interacción-profiláctica, a partir del uso de ejercicios con caballos como elemento de cambio. Se utilizaron como métodos empíricos y técnicas la observación de las sesiones de deportivo, el análisis de documentos, la encuesta a exboxeadores, entrenadores, médicos deportivos, funcionarios y expertos seleccionados, así como los talleres de opinión crítica y socialización entre entrenadores de boxeo. Como resultados se obtuvo un modelo pedagógico del que se derivó una estrategia. Estos aportes fueron constatados mediante la aplicación parcial de la estrategia en un combinado deportivo en Majibacoa, Las Tunas y se demostró su factibilidad para ser generalizada. El artículo que se ofrece tiene como objetivo socializar resultados de la investigación realizada sobre el desentrenamiento deportivo en el boxeo potenciado con el equino-interacción-profiláctica. De manera conclusiva, los aportes teórico y práctico demostraron el cumplimiento del objetivo de la investigación y la solución del problema científico.

A preparação do boxeador implica em mudanças e adaptações fisiológicas para garantir as cargas físicas, psicológicas e sociais às quais o boxeador foi submetido. Ao final dessa etapa, surge o destreinamento esportivo, cuja natureza é eminentemente pedagógica e consiste em desinstalar os componentes que garantiram o acúmulo de cargas durante sua etapa como boxeador ativo, até atingir os níveis de um praticante normal sistemático de Cultura Física. O objetivo deste trabalho consistiu em projetar uma estratégia pedagógica baseada em um modelo semelhante de destreinamento aprimorado com a interação equino-profilática, baseada no uso de exercícios com cavalos como elemento de mudança. Os métodos e técnicas empíricos utilizados foram a observação de sessões esportivas, a análise de documentos, pesquisas com ex-pugilistas, treinadores, médicos esportivos, oficiais e especialistas selecionados, bem como workshops de opinião crítica e socialização entre treinadores de boxe. Como resultado, foi obtido um modelo pedagógico do qual derivou uma estratégia. Essas contribuições foram confirmadas por meio da aplicação parcial da estratégia em uma equipe esportiva em Majibacoa, Las Tunas, e sua viabilidade de generalização foi demonstrada. O objetivo deste artigo é socializar os resultados da pesquisa realizada sobre o destreinamento esportivo no boxe, aprimorado com a interação equino-profilática. Em conclusão, as contribuições teóricas e práticas demonstraram o cumprimento do objetivo da pesquisa e a solução do problema científico.

The preparation of the boxer entails physiological changes and adaptations to guarantee the physical, psychological and social loads to which its practitioners have been subjected. Once this stage is completed, sports detraining appears, the nature of which is eminently pedagogical and consists of uninstalling the components that guaranteed the accumulation of loads during his time as an active boxer, until reaching the levels of a normal systematic practitioner of Physical Culture. The objective of this work was to design a pedagogical strategy based on a model of the same nature for detraining enhanced with equine-interaction-prophylactics, based on the use of exercises with horses as an element of change. Observation of sports sessions, document analysis, a survey of former boxers, coaches, sports doctors, officials and selected experts, as well as critical opinion and socialization workshops among boxing coaches, were used as empirical methods and techniques. As results, a pedagogical model was obtained from which a strategy was derived. These contributions were verified through the partial application of the strategy in a sports complex in Majibacoa, Las Tunas and its feasibility to be generalized was demonstrated. The article offered aims to socialize results of the research carried out on sports detraining in boxing enhanced with equine-interaction-prophylaxis. Conclusively, the theoretical and practical contributions demonstrated the fulfillment of the research objective and the solution of the scientific problem.

In vivo studies could not confirm in vitro prophylactic synergism between Moringa essential oil and Lactobacillus reuteri (MT180537) / Estudos in vivo não puderam confirmar o sinergismo profilático in vitro entre o óleo essencial de Moringa e Lactobacillus reuteri (MT180537)

Aerobic vaginitis (AV) is a recently defined vaginal recurring infection, which is treated with antibiotics. However, excessive and prolonged use of antibiotics disrupts healthy vaginal microflora and leads to the emergence of antibiotic resistance among pathogens. This situation has directed researchers to explore alternative antimicrobials. The current study describes in vitro and in vivo antimicrobial efficacy and pharmaceutical interactions between plant essential oils (EOs) and five lactic acid bacteria (LABs), isolated from the healthy vagina, against E. faecalis, one of the major etiological agents of AV. In vitro experiments confirm good antimicrobial activity of both plant EOs and cell free supernatant (CFS) from LABs. Based on high antimicrobial efficacy, Moringa essential oil (MO) was selected to determine its nature of interaction with CFS of five LAB strains. Synergism was recorded between MO and CFS of L. reuteri (MT180537). To validate in vitro findings, prophylactic responses of individual and synergistic application of MO and L. reuteri (MT180537) were evaluated in an E. faecalis (MW051601) induced AV murine model. The prophylactic efficacy was evidenced by a reduction in intensity of clinical symptoms, E. faecalis (MW051601) count per vaginal tissue along with a reduction in AV associated changes in histological markers of infection in animals receiving Moringa essential oil and L. reuteri (MT180537) alone or in combination. However, significant synergism between Moringa essential oil and L. reuteri (MT180537) could not be observed. Our data confirms the importance of in vivo experiments in deducing pharmacological interactions.

Vaginite aeróbica (VA) é uma infecção vaginal recorrente definida recentemente, que é tratada com antibióticos. No entanto, o uso excessivo e prolongado de antibióticos perturba a microflora vaginal saudável e leva ao surgimento de resistência aos antibióticos entre os patógenos. Esta situação levou os pesquisadores a explorar antimicrobianos alternativos. O presente estudo descreve a eficácia antimicrobiana in vitro e in vivo e as interações farmacêuticas entre óleos essenciais vegetais (OE) e cinco bactérias lácticas (BAL), isoladas de vagina sã, contra E. faecalis, um dos principais agentes etiológicos da AV. Os experimentos in vitro confirmam a boa atividade antimicrobiana de ambos os EOs de plantas e sobrenadante livre de células (CFS) de LABs. Com base na alta eficácia antimicrobiana, o óleo essencial de Moringa (MO) foi selecionado para determinar sua natureza de interação com o sobrenadante livre de células (CFS) de cinco cepas de LAB. Sinergismo foi registrado entre MO e CFS de L. reuteri (MT180537). Para validar os resultados in vitro, as respostas profiláticas da aplicação individual e sinérgica de MO e L. reuteri (MT180537) foram avaliadas em um modelo murino AV induzido por E. faecalis (MW051601). A eficácia profilática foi evidenciada por uma redução na intensidade dos sintomas clínicos, contagem de E. faecalis (MW051601) por tecido vaginal, juntamente com uma redução nas alterações associadas a AV nos marcadores histológicos de infecção em animais que receberam óleo essencial de Moringa e L. reuteri (MT180537) sozinho ou em combinação. No entanto, não foi possível observar sinergismo significativo entre o óleo essencial de Moringa e L. reuteri (MT180537). Nossos dados confirmam a importância dos experimentos in vivo na dedução de interações farmacológicas.

Syagrus flexuosa (Mart.) Becc. (Arecaceae) seedling recruitment at the edge and interior of Cerrado remnants / Recrutamento de plântulas em Syagrus flexuosa (Mart.) Becc. (Arecaceae), na borda e interior de remanescentes de Cerrado

The edge effect has impacts on seed and seedling survival due to modifications in biotic and abiotic factors. Often, large-seeded tree species lost seed vectors in the forest edge due to the rarity or absence of large frugivores at this habitat type. In this study, I compared the seedling abundance and distribution of the palm Syagrus flexuosa between edges and interiors of three large Cerrado remnants. In every remnant, the number of seedlings around parent palms in the edge was smaller than around palm individuals located in the Cerrado interior. Moreover, the distribution of seedlings around parent palms differed between edges and interiors. In the edges, most seedlings were found under parent crowns, while in the interiors, the contrary occurred. The high concentration of seedlings under parent palms suggests a decrease of seed dispersal at the edges. Because S. flexuosa is a widely distributed palm that serves as an important resource for several animals along Cerrado habitats, changes on the regeneration process of this palm due to edge effects can further impact frugivore populations. Therefore, the decline of seedling establishment along forest edges implies changes in the Cerrado regeneration dynamics, which may compromise the persistence of ecological processes and animal communities.

O efeito de borda tem impactos severos na sobrevivência de sementes e plântulas devido a modificações dos fatores bióticos e abióticos. Frequentemente, espécies arbóreas com sementes grandes perdem seus dispersores na borda da floresta devido à raridade ou ausência de grandes frugívoros neste tipo de habitat. Neste estudo, comparei a abundância e distribuição de plântulas de S. flexuosa entre bordas e interiores de três grandes remanescentes de Cerrado. Em cada remanescente, o número de plântulas ao redor das palmeiras-mãe, na borda, era menor do que ao redor dos indivíduos no interior do Cerrado. Nas bordas, a maioria das plântulas foi encontrada junto às plantas mãe, enquanto no interior ocorreu o contrário. A alta concentração de plântulas sob as plantas adultas sugere diminuição da dispersão de sementes nas bordas. Como S. flexuosa é uma palmeira amplamente distribuída que serve como um recurso importante para vários animais nos habitats do Cerrado, mudanças no processo de regeneração dessa palmeira devido aos efeitos de borda podem impactar ainda mais as populações de frugívoros. Portanto, o declínio do estabelecimento de plântulas ao longo das bordas do Cerrado implica em mudanças na dinâmica de regeneração do Cerrado, o que pode comprometer a persistência de processos ecológicos e comunidades animais.

nteraction between FAK/αB-crystalline is important for viability of the glioblastoma cells

Abstract Glioblastoma multiforme is a tumor of the central nervous system. Focal Adhesion Kinase (FAK) and αB-crystalline are two proteins involved in glioblastoma development. In this study, we investigated whether the FAK/αB-crystalline interaction is important for glioblastoma cells, we aimed to investigate the interaction of these two proteins in the glioblastoma multiforme cell line U87-MG. Two peptides named FP01 peptide (derived from αB-crystalline) and FP02 peptide (derived from FAK) were synthesized for this study. Treatment of U87-MG with the peptides FP01 and FP02 in the concentration at 50 µM reduced the viability cellular to around 41% and 51%, respectively. Morphological alterations in the cells treated with the peptides when compared to the control were observed. This study suggests that the interaction between FAK and αB-crystalline is important for the viability of glioblastoma cells

El estudio de la cognición: hacia una perspectiva corporizada / O estudo da cognição: em direção a uma perspectiva incorporada / The study of cognition: towards an embodied perspective / L'étude de la cognition: vers une perspective incarnée

Resumen El campo de la cognición ha tenido una larga historia en la que los modelos formales, el cuerpo y la interacción con el mundo físico y social han tenido significados y papeles variados. En los últimos años, las propuestas han intentado reintroducir el cuerpo y la variabilidad cognitiva resultante de la sensibilidad a contextos ricos e impredecibles. Este artículo presenta el enactivismo autopoiético, una de las versiones esenciales de las teorías encarnadas dentro de las ciencias cognitivas, señalando algunas limitaciones de las teorías clásicas de procesamiento de la información y sus nociones de representación. En este distanciamiento, las ciencias cognitivas han recuperado el cuerpo, la sensibilidad y flexibilidad de los procesos cognitivos, la naturaleza dinámica de la experiencia y el valor de los sistemas culturales que sustentan la actividad cognitiva.

Resumo O campo da cognição tem uma longa história na qual modelos formais, o corpo, e a interação com o mundo físico e social tiveram significados e papéis variados. Nos últimos anos, as propostas tentaram reintroduzir o corpo e a variabilidade cognitiva resultante da sensibilidade a contextos ricos e imprevisíveis. Este artigo apresenta o enativismo autopoiético, uma das versões essenciais das teorias corporizadas dentro das ciências cognitivas, apontando algumas limitações das teorias clássicas de processamento de informação e as suas noções de representação.

Abstract The field of cognition has had a long history where formal models, the body, and interaction with the physical and social world have had varied meanings and roles. In recent years, proposals have tried to reintroduce the body and the cognitive variability resulting from sensitivity to rich and unpredictable contexts. This article presents the autopoietic enactivism, one of the essential versions of embodied theories within the cognitive sciences, pointing out some limitations of classical information processing theories and their notions of representation. In this distancing, cognitive sciences have recovered the body, the sensitivity and flexibility of cognitive processes, the dynamic nature of experience, and the value of the cultural systems that support cognitive activity.

Ces dernières années, des propositions ont tenté de réintroduire le corps et la variabilité cognitive résultant de la sensibilité à des contextes riches et imprévisibles. Cet article présente l'enactivisme autopoïétique, l'une des versions essentielles des théories incarnées au sein des sciences cognitives, en soulignant certaines limites des théories classiques du traitement de l'information et de leurs notions de représentation. Avec cet écartement, les sciences cognitives ont récupéré le corps, la sensibilité et la flexibilité des processus cognitifs, la nature dynamique de l'expérience et la valeur des systèmes culturels qui soutiennent l'activité cognitive.

A importância do corpo junto à função de reconhecimento / The importance of the body in the recognition function / La importancia del cuerpo en la función de reconocimiento / L'importance du corps et la fonction de reconnaissance

Resumo O reconhecimento se apresenta como via pela qual o psiquismo poderá se desenvolver e complexificar a partir de seu encontro com o outro e as afetações que este irá suscitar. Da mesma forma, o reconhecimento se apresenta enquanto movimento de afirmação de si por um elemento do meio externo com o qual o indivíduo se relaciona. Nesse contexto, vemo-nos diante de modalidades de interação da personalidade por meio de vias não-verbais, o que confere grande relevância ao corpo em nosso estudo, apresentando-se enquanto palco que torna possível a expressão e reconhecimento de determinados conteúdos psíquicos que de outra forma não poderiam ser postos em cena nas relações.

Abstract Recognition is presented as a way the psyche can develop and complexify from its encounter with the other and the affects this will arouse. Likewise, recognition is presented as a movement of affirming oneself by an element of the external environment the individual relates to. In this context, we are faced with modalities of personality interaction via non-verbal means, giving the body great relevance in our study, which presents itself as a stage that makes it possible to express and recognize certain psychic contents that could not otherwise be brought into play in relationships.

Resumen El reconocimiento se presenta como una vía por la cual la psique puede desarrollarse y complejizarse a partir de su encuentro con el otro y los afectos que este generará. Asimismo, el reconocimiento manifiesta como un movimiento de afirmación por parte de un elemento del entorno externo con el que se relaciona el individuo. En este contexto, nos encontramos ante modalidades de interacción de la personalidad a través de vías no verbales, lo que otorga gran importancia al cuerpo en nuestro estudio, presentándose como una etapa que posibilita la expresión y reconocimiento de ciertos contenidos psíquicos que de otra manera no podrían ser puestos en juego en las relaciones.

Résumé La reconnaissance est présentée comme un moyen par lequel le psychisme peut se développer et se complexifier en fonction de sa rencontre avec l'autre et des affectations que cela va susciter. De même, la reconnaissance est présentée comme un mouvement d'affirmation de soi par un élément de l'environnement extérieur avec lequel l'individu est en relation. Dans ce contexte, nous sommes confrontés à des modalités d'interaction de la personnalité par des voies non verbales, ce qui donne une grande importance au corps dans notre étude, se présentant comme une étape qui rend possible l'expression et la reconnaissance de certains contenus psychiques qui, autrement, ne pourrait pas être joué dans les relations.

Effects of dialogic reading for comprehension (LuDiCa) on the social interaction of autistic adolescents and their peers

Abstract Background In today's contemporary world, relationships take a prominent role in the lives of adolescents. However, challenges related to mutual understanding and a lack of inclusive environments can often lead to autistic teens feeling excluded. Objective In order to assess the impact of naturalistic interventions on interpersonal relationships, we conducted an experimental test utilizing Dialogic Reading for Comprehension (LuDiCa) in online reading circles with groups comprising both autistic and neurotypical adolescents. Our focus was on exploring its relevance for enhancing social interaction, particularly in terms of conversational acts, sharing experiences, initiations, and questions. Methods Five autistic and five neurotypical students between 11 and 15 years old from a public school in Brasilia, Federal District, participated. We paired groups A and B (made up of trios of teenagers) and groups C and D (made up of pairs) in a multiple baseline design per reading group, in which all groups went through the baseline conditions (BL), intervention (LuDiCa) and maintenance. Results LuDiCa increased the frequency of conversational acts of both autistic participants and neurotypical peers. In addition, the intervention favored initiations, questions, and sharing experiences, through the shared activity of reading and talking about a work of fiction. Participants rated the intervention in relation to the platform, the book, the reading facilitator, and interaction with peers. We discuss the potential of the facilitator's role in favoring interactions and the potential of LuDiCa as a joint activity for the engagement of adolescents. We also include suggestions for future research focused on the online context and discuss some limitations of the LuDiCa intervention. Conclusion In summary, our study offers initial experimental evidence demonstrating the positive impact of LuDiCa on social interaction behaviors among both autistic and neurotypical adolescents within an inclusive setting.

O lado obscuro da internet: uma revisão de literatura sobre o comportamento antissocial online / The internet's dark side: a literature review on antissocial online behaviour / El lado oscuro de internet: una revisión de la literatura sobre el comportamiento antisocial online

O objetivo do estudo foi realizar uma revisão sistemática da literatura acerca do comportamento antissocial online e, também, categorizar esses comportamentos e observar aspectos psicossociais relacionados. Para tanto, foi utilizada uma síntese qualitativa, incluindo estudos quantitativos publicados entre 2016-2020 nas bases de dados Scopus, PsycInfo, Pepsic e Scielo. Vinte e cinco estudos se adequaram às análises. Os resultados demonstraram a existência de quatro categorias de comportamento antissocial online: cyberbullying, trollagem, comportamento antissocial sexual, e cyberstalking. A tétrade sombria (narcisismo, psicopatia, Maquiavelismo e sadismo) mostrou-se o preditor mais consistente dessas categorias nos estudos. O estudo alcançou os objetivos propostos, preenchendo duas lacunas: a inexistência de categorização do comportamento antissocial online e a escassez de estudos brasileiros sobre o tema

The study aimed to conduct a systematic literature review on antisocial online behavior. The objective was also to categorize these behaviors and observe related psychosocial aspects. To this end, a qualitative synthesis was used, including quantitative studies published between 2016-2020 in the Scopus, PsycInfo, Pepsic, and Scielo databases. 25 studies fitted the analyzes. The results demonstrated the existence of four antisocial online behavior categories: cyberbullying, trolling, sexual antisocial behavior, and cyberstalking. The dark tetrad (narcissism, sychopathy, Machiavellianism, and sadism) was the most consistent predictor of these categories among studies. The research fulfilled the proposed purposes, filling two literature gaps: The lack of categorization of antisocial online behavior; and the scarcity of Brazilian studies on the topic

Understanding adoption of Electronic Medical Records (EMRs) during a health emergency: An analysis of EMR usage logs from rural health facilities in the Philippines

Background and Objective@#The adoption of electronic medical records (EMRs) in the Philippines has been initiated and adjusted since the last decade through the Philippine eHealth Agenda framework. EMRs are known to improve clinical management and have been widely adopted in advanced economies. However, empirical research on EMR implementation remains limited. This study aims to determine how public primary health care facilities in the country interacted with EMRs before and during the COVID-19 pandemic to understand EMR adoption.@*Methods@#More than 270,000 records generated from EMR usage logs in six rural primary health facilities in Western Visayas were analyzed. Average time of EMR use during work hours was estimated and compared before and during the pandemic. EMR adoption based on specific EMR features used was also determined. @*Results@#In 2020, EMR use ranged from less than one hour to more than eight hours in selected rural health units (RHUs). There was a statistical increase and decrease in use of features during the pandemic. Some EMR users had efficient use indicated by complete adoption of EMR features although such features were not as frequently used as those pertaining to basic adoption. @*Conclusion@#This study demonstrates that for EMR use in rural settings, progressive use from basic to complete may vary among users. Public health emergencies such as a pandemic may also affect EMR use. Future research directions should explore other mechanisms which affect user behavior and encourage full adoption of technology such as use of games or non-monetary incentives.

Functional mechanisms of WRKY transcription factors in regulating plant response to abiotic stresses / 生物工程学报

WRKYs is a unique family of transcription factors (TFs) in plants, and belongs to the typical multifunctional regulator. It is involved in the regulation of multiple signaling pathways. This type of transcription factor is characterized to contain about 60 highly conservative amino acids as the WRKY domain, and usually also has the Cys2His2 or Cys2His-Cys zinc finger structure. WRKYs can directly bind to the W-box sequence ((T)(T) TGAC (C/T)) in the promoter region of the downstream target gene, and activate or inhibit the transcription of the target genes by interacting with the target protein. They may up-regulate the expression of stress-related genes through integrating signal pathways mediated by abscisic acid (ABA) and reactive oxygen species (ROS), thus playing a vital role in regulating plant response to abiotic stresses. This review summarizes the advances in research on the structure and classification, regulatory approach of WRKYs, and the molecular mechanisms of WRKYs involved in response to drought and salt stresses, and prospects future research directions, with the aim to provide a theoretical support for the genetic improvement of crop in response to abiotic stresses.

Multisensory Conflict Impairs Cortico-Muscular Network Connectivity and Postural Stability: Insights from Partial Directed Coherence Analysis / 神经科学通报·英文版

Sensory conflict impacts postural control, yet its effect on cortico-muscular interaction remains underexplored. We aimed to investigate sensory conflict's influence on the cortico-muscular network and postural stability. We used a rotating platform and virtual reality to present subjects with congruent and incongruent sensory input, recorded EEG (electroencephalogram) and EMG (electromyogram) data, and constructed a directed connectivity network. The results suggest that, compared to sensory congruence, during sensory conflict: (1) connectivity among the sensorimotor, visual, and posterior parietal cortex generally decreases, (2) cortical control over the muscles is weakened, (3) feedback from muscles to the cortex is strengthened, and (4) the range of body sway increases and its complexity decreases. These results underline the intricate effects of sensory conflict on cortico-muscular networks. During the sensory conflict, the brain adaptively decreases the integration of conflicting information. Without this integrated information, cortical control over muscles may be lessened, whereas the muscle feedback may be enhanced in compensation.

Presenteeism and social interaction in the "new normal" in Japan: a longitudinal questionnaire study

BACKGROUND@#Although social interaction and social support during the "new normal" due to coronavirus disease 2019 (COVID-19) may be related to presenteeism, the effect between these factors has not been clear for Japanese workers. The aim of this study was to describe the presenteeism of Japanese workers with reference to social interaction and social support following the lifestyle changes due to COVID-19 and to assess whether social interaction and social support affected their presenteeism.@*METHODS@#The data were obtained from internet panel surveys from October 2020. Descriptive statistics were calculated, and multiple linear regression was conducted using the data from the first, fourth and fifth surveys, which were conducted during October to November 2020, July to August 2021, and September to October 2021, respectively. To measure presenteeism, questions from "absenteeism and presenteeism questions of the World Health Organization's Heath and Work Performance Questionnaire", short version in Japanese was utilized. Multiple linear regressions were conducted to investigate the effects of social interaction and social support-related factors on presenteeism.@*RESULTS@#A total of 3,407 participants were included in the analysis. The mean score of absolute presenteeism from the fifth survey was 58.07 (SD = 19.71). More time spent talking with family, a larger number of social supporters and a higher satisfaction level for social support were associated with a higher absolute presenteeism score.@*CONCLUSIONS@#Our results suggested that social support reduced the presenteeism of the Japanese workers during the "new normal" due to the COVID-19 pandemic. Social interaction with family also relieved presenteeism.

Clinical treatment and management of invasive fungal disease in recipients of solid organ transplantation / 器官移植

With widespread application of solid organ transplantation (SOT), the incidence of postoperative invasive fungal disease (IFD) in SOT recipients has been increased year by year. In recent years, the awareness of preventive antifungal therapy for SOT recipients has been gradually strengthened. However, the problem of fungal resistance has also emerged, leading to unsatisfactory efficacy of original standardized antifungal regimens. Drug-drug interaction and hepatorenal toxicity induced by drugs are also challenges facing clinicians. In this article, the characteristics of drug-drug interaction and hepatorenal toxicity among triazole, echinocandin and polyene antifungal drugs and immunosuppressants were reviewed, and postoperative preventive strategies for IFD in different types of SOT recipients and treatment strategies for IFD caused by infection of different pathogens were summarized, aiming to provide reference for physicians in organ transplantation and related disciplines.

Screening and bioinformatics analysis of key autophagy-related genes in alcoholic hepatitis / 器官移植

Objective To screen key autophagy-related genes in alcoholic hepatitis (AH) and investigate potential biomarkers and therapeutic targets for AH. Methods Two AH gene chips in Gene Expression Omnibus (GEO) and autophagy-related data sets obtained from MSigDB and GeneCards databases were used, and the key genes were verified and obtained by weighted gene co-expression network analysis (WGCNA). The screened key genes were subject to gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), protein-protein interaction (PPI) and immune infiltration analyses. Messenger RNA (mRNA)- microRNA (miRNA) network was constructed to analyze the expression differences of key autophagy-related genes during different stages of AH, which were further validated by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) in the liver tissues of AH patients and mice. Results Eleven autophagy-related genes were screened in AH (EEF1A2, CFTR, SOX4, TREM2, CTHRC1, HSPB8, TUBB3, PRKAA2, RNASE1, MTCL1 and HGF), all of which were up-regulated. In the liver tissues of AH patients and mice, the relative expression levels of SOX4, TREM2, HSPB8 and PRKAA2 in the AH group were higher than those in the control group. Conclusions SOX4, TREM2, HSPB8 and PRKAA2 may be potential biomarkers and therapeutic targets for AH.

Identification, expression and protein interaction analysis of Aux/IAA and ARF gene family in Senna tora L / 药学学报

The early response of plant auxin gene family Aux/IAA (auxin/indole-3-acetic acid) and its interaction with auxin response factor (ARF) are important pattern to regulate plant growth and development. This work identified 28 StoIAA and 24 StoARF members based on the whole genome data of the medicinal plant Senna tora L., which were classified into 10 and 8 subfamilies, respectively. Phylogenetic tree and collinearity analysis showed that S. tora has close evolutionary relationship with the IAA and ARF homologous genes of Glycine max, Medicago truncatula, and the segment duplication events dominate the expansion of StoIAA and StoARF. Gene structure analysis showed that the vast majority of StoIAA and StoARF contain characteristic conserved domain. Transcriptome data showed that StoIAAs and StoARFs were expressed in leaves, roots and seeds, some members had tissue specific expression. The StoIAA and StoARF promoter region most contain functional elements related to stress response, growth and development, hormone induction and secondary metabolism. In addition, gene expression analysis showed that many StoIAAs and StoARFs can quickly respond to drought and salt stress and exhibited same expression patterns under both stress condition. The yeast two-hybrid experiment confirmed that StoARF8 and StoARF10 exhibit varying degrees of interaction with multiple StoIAA proteins, respectively. The above results provide a basis for further biological functional analysis of the Aux/IAA and ARF gene family of S. tora.

Research progress of antineoplastic drugs targeting platelets / 中国药理学通报

Platelets have long been recognized as key players in hemostasis and thrombosis; however, there is growing evidence that they are also involved in cancer. Preclinical and clinical studies have shown that platelets can promote tumorigenesis and metastasis through various crosstalks between platelets and cancer cells. Platelets play an active role in all stages of tumorigenesis, including tumor growth, tumor cell extravasation, and metastasis. In addition, thrombocytosis in cancer patients is associated with poor patient survival. Platelets are also well-placed to coordinate local and distant tumor-host interactions due to the a- bundance of microparticles and exosomes. Therefore, antitumor drugs targeting platelets have great development and application prospects. The following will review the research progress of anti-tumor drugs targeting platelets.

Professionalism Education Function of Ceremony in Medical Colleges from the Perspective of Interaction Ritual Chains Theory: Take the Graduation Ceremony of Peking University Health Science Center in 2020 as an Example / 中国医学伦理学

Taking the graduation ceremony of Peking University Health Science Center in 2020 as the observation object, this paper used Collins’ Interactive Ritual Chains Theory to analyze the form, theme and featured part of this ceremony from the dimensions of physical co-presence, barrier to outsiders, joint focus of attention and shared mood. It was found that the ceremony in medical colleges had an impact on the cognition, behavior and spirit of junior medical students in terms of group identity, emotional energy, group symbols and moral sense, which played a good role in professionalism education. Some enlightenment and thinking were obtained on this basis to provide some references for medical colleges to give full play to the educational function of the professionalism in the post-epidemic era.
