Analysis of the Research Hotspot of Exosomes in Cardiovascular Disease: A Bibliometric-based Literature Review.

OBJECTIVE: To investigate the current status and development trend of research on exosomes in cardiovascular disease (CVD) using bibliometric analysis and to elucidate trending research topics. METHODS: Research articles on exosomes in CVD published up to April 2022 were retrieved from the Web of Science database. Data were organized using Microsoft Office Excel 2019. CiteSpace 6.1 and VOSviewer 1.6.18 were used for bibliometric analysis and result visualization. RESULTS: Overall, 256 original research publications containing 190 fundamental research publications and 66 clinical research publications were included. "Extracellular vesicle" was the most frequent research keyword, followed by "microrna," "apoptosis," and "angiogenesis." Most publications were from China (187, 73.05%), followed by the United States (57, 22.27%), the United Kingdom (7, 2.73%), and Japan (7, 2.73%). A systematic review of the publications revealed that myocardial infarction and stroke were the most popular topics and that exosomes and their contents, such as microRNAs (miRNAs), play positive roles in neuroprotection, inhibition of autophagy and apoptosis, promotion of angiogenesis, and protection of cardiomyocytes. CONCLUSION: Research on exosomes in CVD has attracted considerable attention, with China having the most published studies. Fundamental research has focused on CVD pathogenesis; exosomes regulate the progression of CVD through biological processes, such as the inflammatory response, autophagy, and apoptosis. Clinical research has focused on biomarkers for CVD; studies on using miRNAs in exosomes as disease markers for diagnosis could become a future trend.

La solidez de la investigación homeopática fundamental / The strength of fundamental homeopathic research

La investigación fundamental en homeopatía ha avanzado considerablemente en los últimos 20 años: desde estudios exploratorios con animales y plantas hasta la caracterización de los efectos sistémicos de los medicamentos homeopáticos y estudios in vitro con sistemas celulares aislados para evaluar los cambios en los mecanismos de adaptación celular y señalización intracelular frente a tratamientos homeopáticos variables. El número de artículos publicados a lo largo del tiempo ha permitido realizar varias revisiones sistemáticas. Recientemente, la demostración de que los medicamentos homeopáticos podrían modificar las funciones celulares a través de mecanismos epigenéticos (metilación y desmetilación de ADN) preparó el camino para un campo de investigación completamente nuevo. En paralelo, el descubrimiento de las nanopartículas y propiedades físicas específicas de las diluciones homeopáticas ha arrojado luz hacia un campo antes poco conocido, dado que se consideraba que las diluciones homeopáticas no consistían más que de agua. Así las cosas, los retos para el futuro conciernen a la demostración, o no, de la interrelación entre ambos fenómenos.

Fundamental research in homeopathy has much advanced in the past 20 years. From exploratory studies with animals and plants to the characterization of the systemic effects of homeopathic medicines and in vitro studies with isolated cell systems to assess changes in the mechanisms of cell adaptation and intracellular signaling facing variable homeopathic treatments. The amount of articles published over time enabled several systematic reviews. Recently, demonstration that homeopathic medicines might modify cell functions through epigenetic mechanisms (DNA methylation and demethylation) paved the road for a fully new field of research. In parallel, the discovery of nanoparticles and specific physical properties of homeopathic dilutions brought light to a previously poorly known field, as it was believed that homeopathic dilutions consist in nothing but water. Thus being, challenges for the future concern the demonstration, or not, of the interrelationship between both phenomena.

Animal Model of Premature Ovarian Insufficiency Based on Data Mining / 中国实验方剂学杂志

ObjectiveTo study the modeling characteristics of the animal model of premature ovarian insufficiency and provide references for the standardization of the animal model of premature ovarian insufficiency， thus offering a better research basis to the pathogenesis， diagnosis， and treatment of the disease. MethodThe animal experimental literature of premature ovarian insufficiency in the past decade was obtained by searching China National Knowledge Infrastructure （CNKI）， Wanfang， VIP Chinese Technology Periodical Database， China Biology Medicine （CBM）， and PubMed. The types of experimental animals， modeling methods， dosage， administration scheme， modeling standards， and detection indicators were summarized. The frequency analysis was performed with Excel， the association rule analysis was performed with SPSS Modeler 18.0， and the results were visually upgraded with Cytascape 3.6.1. ResultA total of 281 articles were included， and most animal experiments on premature ovarian insufficiency were performed on SD rats or BALB/c mice. Most modeling methods were iatrogenic induction， and the main modeling drug was cyclophosphamide. Erestrous cycle disorder was selected as the modeling standard. Ovarian histomorphology， estradiol， follicle stimulating hormone， and estrous cycle were selected as the detection indicators to comprehensively evaluate the model from multiple aspects. ConclusionSD rats are mostly used to induce modeling in animal experiments on premature ovarian insufficiency through first intraperitoneal injection of cyclophosphamide 50 mg·kg-1 and 8 mg·kg-1·d-1 from the next day for 14 d， which has the advantages of easy operation， high modeling rate， and consistency with the disease pathogenesis. This paper can provide references for basic animal experimental research of premature ovarian insufficiency.

A public health mission in Canada in response to the coronavirus disease 2019 (COVID-19) pandemic.

Many governments in the world reacted to the coronavirus disease 2019 pandemic by swiftly offering stimulus packages to their populations. While public unpreparedness was dramatic, it was not unexpected: many alarms had been sounded. Strategies by the federal and various provincial governments of Canada in core sectors predisposed the country to the current situation and weakened its capacity to respond adequately. This paper reviews the cumulative effects of these strategic orientations: a deficient investment strategy in fundamental science; disconnect between laboratory work and the country's capacity to produce vaccines and antiviral drugs; the priority of cost efficiency that led to overwhelming dependency on foreign production of medical supplies; and dramatic spending cuts in public health. We will discuss a Mission strategy to exit the crisis that takes a long-term perspective, in which public interest and public health, combined with a strong State leadership, stimulate innovation and collaboration between national and international actors.

[Goals, motivations, and difficulties of young oncology residents]. / Objectifs, motivations et difficultés des internes en phase socle en oncologie.

INTRODUCTION: The Association for education and research of interns in oncology (AERIO) conducted a national survey of the 2020-year oncology residents promotion in the "phase socle". The objective was to collect and analyze their motivations, as well as the objectives and limitations in the life and career of the residents during this first year of residency. METHODS: A questionnaire included 45 closed questions divided into 6 sections describing: the demographic characteristics of the population, the commitment of the students' and their clinical and academic expectations in the, their training, their life and career objectives, and their commitment in associative life. RESULTS: Seventy-eight of 119 residents participated (66%), of which 68 (87.2%) completed the questionnaire entirely. The population was predominantly women (60%) with a median age of 24 years. The choice between medical or radiation oncology was mostly undefined (87%) and 15% of the residents considered to change their medical specialty. The average hospital work time reported was predominantly between 45 and 65hours per week (83%). Sixty-nine percent were primarily interested in clinical research. One out of two residents (52%) did not have access to their half-day of training per week. DISCUSSION: This national survey made possible to analyze the perception of oncology young residents, as well as their career aspirations and their relationship to research.

Phototrophic Co-cultures From Extreme Environments: Community Structure and Potential Value for Fundamental and Applied Research.

Cyanobacteria are found in most illuminated environments and are key players in global carbon and nitrogen cycling. Although significant efforts have been made to advance our understanding of this important phylum, still little is known about how members of the cyanobacteria affect and respond to changes in complex biological systems. This lack of knowledge is in part due to our dependence on pure cultures when determining the metabolism and function of a microorganism. We took advantage of the Culture Collection of Microorganisms from Extreme Environments (CCMEE), a collection of more than 1,000 publicly available photosynthetic co-cultures maintained at the Pacific Northwest National Laboratory, and assessed via 16S rRNA amplicon sequencing if samples readily available from public culture collection could be used in the future to generate new insights into the role of microbial communities in global and local carbon and nitrogen cycling. Results from this work support the existing notion that culture depositories in general hold the potential to advance fundamental and applied research. Although it remains to be seen if co-cultures can be used at large scale to infer roles of individual organisms, samples that are publicly available from existing co-cultures depositories, such as the CCMEE, might be an economical starting point for such studies. Access to archived biological samples, without the need for costly field work, might in some circumstances be one of the few remaining ways to advance the field and to generate new insights into the biology of ecosystems that are not easily accessible. The current COVID-19 pandemic, which makes sampling expeditions almost impossible without putting the health of the participating scientists on the line, is a very timely example.

The current state and future prospects of the fundamental research on pediatric otorhinolaryngology: an analysis of application and funding data of the National Natural Science Foundation of China from 2009 to 2019.

BACKGROUND: This study aimed to summarize the current situation and deficiencies of the fundamental research on pediatric otolaryngology-head and neck science. It is hoped that the results can provide support for the long-term development of the basic research on this subject. METHODS: Information concerning the applications to and funding from the National Natural Science Foundation of China (NSFC) for otolaryngology-head and neck from 2009 to 2019 was collected and analyzed. RESULTS: In the past 10 years, pediatric otolaryngology-head and neck science received 150 applications, accounting for 2.92% of all applications for otolaryngology-head and neck science. Ultimately, 20 projects were funded, accounting for 2.17% of all the funded projects. There were 88 applications for children's ear science and hearing-related research, accounting for 58.67% of the applications for pediatric otolaryngology-head and neck science. Furthermore, 14 approved grants focused on cochlear implants and the genetics and mechanisms of deafness. There were 25 applications related to children's nasal science, particularly allergic rhinitis, accounting for 16.67% of the total applications. Of these, 4 applications were funded, and these mainly focused on the disease regulation and pathogenesis of allergic rhinitis. A total of 30 applications related to children's laryngopharyngeal diseases, accounting for 20% of the applications, mainly focused on obstructive sleep apnea syndrome (OSAS), adenoid hypertrophy, and tonsil hypertrophy, with only 1 application being funded. The scientific research on children's head and neck was mainly related to laryngeal papilloma and lymphatic vascular malformation, with 7 projects being applied for and 2 being funded. CONCLUSIONS: The fundamental research of pediatric otolaryngology-head and neck science in China is at a relatively weak level and lags behind the average level of the discipline. There are relatively few basic researchers engaged in pediatric otolaryngology-head and neck science, and the dominant research units are relatively concentrated. The basic research of children's ear science is relatively advanced in each subspecialty, so the basic research on children's unique congenital and hereditary diseases should be further strengthened.

Evaluating "startup readiness" for researchers: case studies of research-based startups with biopharmaceutical research topics.

For research domains such as life sciences, which pursue fundamental scientific understanding and applications intended for immediate use, academic entrepreneurship has played a pivotal role in commercialization. This paper presents an evaluation method of researchers related to user-inspired fundamental research, using global databases of startup finances and academic research papers of "startup readiness." Case studies of startups related to biopharmaceutical research topics suggest that the biopharmaceutical field has rich opportunities stemming from scientific research, commercialization, and entrepreneurship. This evaluation method sorts specific industry segments by which financing activities are active, and by which related growing research topics attract increased academic attention. We constructed networks of author citation and co-authorship from paper citation networks related to research topics in industry segments in the biopharmaceutical domain. Results obtained across all research topics we surveyed demonstrated that authors in the top 10% of degree centrality ranking in both networks are far more likely to be startup participants than other authors. Our computational approach might provide convenient, dynamic, global, and real-time understanding of the "startup readiness" of researchers working with research topics for which academic attention is emerging in actively financed biopharmaceutical fields.

Lumbar Intervertebral Motion Analysis During Flexion and Extension Cinematographic Recordings in Healthy Male Participants: Protocol.

BACKGROUND: Physiological motion of the lumbar spine is a subject of interest for musculoskeletal health care professionals, as abnormal motion is believed to be related to lumbar conditions and complaints. Many researchers have described ranges of motion for the lumbar spine, but only a few have mentioned specific motion patterns of each individual segment during flexion and extension. These motion patterns mostly comprise the sequence of segmental initiation in sagittal rotation. However, an adequate definition of physiological motion of the lumbar spine is still lacking. The reason for this is the reporting of different ranges of motion and sequences of segmental initiation in previous studies. Furthermore, due to insufficient fields of view, none of these papers have reported on maximum flexion and extension motion patterns of L1 to S1. In the lower cervical spine, a consistent pattern of segmental contributions was recently described. In order to understand physiological motion of the lumbar spine, it is necessary to systematically study motion patterns, including the sequence of segmental contribution, of vertebrae L1 to S1 in healthy individuals during maximum flexion and extension. OBJECTIVE: This study aims to define the lumbar spines' physiological motion pattern of vertebrae L1, L2, L3, L4, L5, and S1 by determining the sequence of segmental contribution and the sequence of segmental initiation of motion in sagittal rotation of each vertebra during maximum flexion and extension. The secondary endpoint will be exploring the possibility of analyzing the intervertebral horizontal and vertical translation of each vertebra during maximum flexion and extension. METHODS: Cinematographic recordings will be performed in 11 healthy male participants, aged 18-25 years, without a history of spine problems. Cinematographic flexion and extension recordings will be made at two time points with a minimum 2-week interval in between. RESULTS: The study has been approved by the local institutional medical ethical committee (Medical Research Ethics Committee of Zuyderland and Zuyd University of applied sciences) on September 24, 2018. Inclusion of participants will be completed in 2020. CONCLUSIONS: If successful, these physiological motion patterns can be compared with motion patterns of patients with lumbar conditions before or after surgery. Ultimately, researchers may be able to determine differences in biomechanics that can potentially be linked to physical complaints like low back pain.

[A GERCOR-AERIO national survey of oncology residents in France: Current setting and expectations regarding post-internship and research]. / État des lieux et attentes des internes d'oncologie français concernant le post-internat et la recherche : une enquête nationale GERCOR-AERIO.

INTRODUCTION: The demographics of oncology residents has changed since 2010 with the increase in the size of promotions. The evolution of the residents' aspirations towards research and their future exercise in parallel with these demographic changes has not been assessed. METHODS: A questionnaire was developed by a working group from GERCOR (cooperative group in oncology), involving clinicians, researchers, GERCOR members, and residents. It consisted of 62 questions divided into 7 sections: demographics, medical thesis, post-residency, mobility, publication activity, basic research, and clinical/translational research. The national survey was published online by the Association d'enseignement et de recherche des internes en oncologie (AERIO). RESULTS: In total, 143 residents participated, of which 116 (81.1%) completed the questionnaire entirely. The population was representative of the current demographics, with a majority of women (65.0%), a median age of 28 years, and 39.7% of residents from Paris region. The unsupervised analysis revealed four profiles of residents, including one group strongly committed to research (16.8%), one group with moderate involvement (41.3%) and one group that did not seem interested in research (14.7%). Uncertainty about future position and lack of time and interaction with researchers appeared to be the main barriers to involvement of residents in research. DISCUSSION: This national survey provided useful information about the residents' perspective to academic research. It may serve as a basis for proposing measures adapted to their expectations.

The Case for Basic Biological Research.

The majority of biomedical and biological research relies on a few molecular biology techniques. Here we show that eight key molecular biology techniques would not exist without basic biological research. We also find that the scientific reward system does not sufficiently value basic biological research into molecular mechanisms.

As evidências a favor da homeopatia e as ciências básicas / Evidence for the homeopathic principles in the basic sciences

Como toda área da medicina, a homeopatia é tanto arte quanto ciência. Enquanto a pesquisa clínica visa responder "se" e "quando" os medicamentos homeopáticos são capazes de restabelecer a saúde, as ciências básicas ­ biologia, imunologia, patologia, química, física e farmacologia ­ geram diversas hipóteses plausíveis para dar conta do "como" agem os medicamentos diluídos e dinamizados (MDD) em modelos experimentais rigorosos. A ação farmacodinâmica dos MDD depende do fornecimento de pequenas quantidades de informação a alvos orgânicos específicos, de maneira a restabelecer um comportamento mais próximo do estado ótimo de saúde. Alguns mecanismos de ação dos MDD podem ser identificados em estudos de laboratório. O princípio de semelhança terapêutica pode ser observado em modelos horméticos, de acordo com a lei de Arndt-Schutz, nos quais a inversão de efeitos é obtida modificando a dose. Igualmente, em modelos de tipo Wilder, são comparados organismos estressados e normais. No entanto, a hormese utiliza medicamentos em pequenas doses, enquanto na homeopatia são utilizados medicamentos em diluições além da faixa material, que além disso precisam ser agitados. O presente artigo dedica atenção especial ao modelo de degranulação dos basófilos, que em 2018 completa 30 anos de desenvolvimento. Igualmente são abordados os trabalhos do nosso grupo, na Universidade de Verona, Itália. (AU)

As any other medical field, homeopathy is both art and science. Clinical research seeks to answer the questions on "whether" and "when" homeopathic medicines are able to restore health. In turn, the fundamental sciences­biology, immunology, pathology, chemistry, physics and pharmacology­generate plausible hypothesis to explain "how" serially diluted and agitated medicines (SDAM) act in rigorous experimental models. The pharmacodynamic action of SDAM depends on the supply of subtle information input to specific body targets in order to restore a pattern of behavior closer to optimal health. Some mechanisms of action of SDAM might be identified in laboratory studies. The therapeutic similarity principle might be observed in hormesis models, according to Arndt-Schutz's law, in which effect inversion is obtain through changes of dose. Wilder-like models compared stressed and healthy subjects. However, hormesis uses drugs in small doses, while homeopathy uses medicines diluted beyond the scope of matter, which in addition must be agitated. In the present article I paid special attention to the basophil degranulation, as in 2018 it completes its 30th anniversary. I also summarized the results of our work at University of Verona, Italy.
