RESUMO
ABSTRACT Objective. Basic and translational research in pediatric cancer are essential to improve patient care. To critically assess the developments achieved in these areas in Latin America, we systematically reviewed information published between 2013 and 2023. Methods. Studies of basic and translational research performed by investigators in Latin America evaluating pediatric malignant solid and central nervous system tumors were retrieved from PubMed. Original articles published in English between 2013 and 2023 were included. Collaborations among Latin American authors or among Latin American authors working with researchers from other continents were also included. Studies were excluded if they focused only on adults or on basic research in tumor biology not specifically related to the tumor types analyzed in this review. Results. A total of 550 articles were retrieved, but after removal of duplicates, 514 articles were included in the analysis, the majority of which were authored by researchers affiliated with institutions in Argentina, Brazil and Mexico. These countries also had the highest number of collaborations on original articles published with authors from Europe and North America. Argentina had the highest number of collaborations on original publications, with coauthors from Brazil and Uruguay. The median impact factor of the 244 journals in which articles were published was 3.5. The most commonly studied tumors were osteosarcomas, neuroblastomas and medulloblastomas; the most commonly studied areas were molecular analysis, tumor cell biology and biomarkers. Conclusions. In Latin America, research in pediatric oncology is on the agenda, despite a notable disparity in publication rates and frequency of collaboration between countries. There is a need to strengthen scientific collaboration within Latin America and with countries from other continents to promote research and to develop novel treatment strategies that reflect the local needs of children in Latin America who have solid tumors and brain cancer.

RESUMO
@#Objective To explore the factors affecting the stability of high concentration variable domain of heavy-chain antibody-Fc(VHH-Fc) fusion protein.Methods Three groups of forced degradation experiments,shaking,light and 40℃ high temperature were set up.Differential scanning fluorimetry,dynamic light scattering(DLS) and ultra performance liquid chromatography-mass spectrometry(UPLC-MS) were used to detect the effects of the three forced degradation conditions on the conformational stability,colloidal stability,average hydrodynamic diameter and post-translational modifications of high concentration VHH-Fc fusion protein.Results Under the light condition,the onset temperature of unfolding(T_(onset)),melting temperature(T_m) and aggregation onset temperature(T_(agg)) of high concentration VHH-Fc fusion protein decreased the most,and the oxidation ratio of Met160 and Met266 increased significantly.Under the condition of shaking,the variation of the diffusion interaction parameter(k_D) and the average hydrodynamic diameter was the largest.Conclusion Light can significantly reduce the conformational stability of high concentration VHH-Fc fusion protein and induce methionine oxidation.Shaking has the most significant effect on its colloidal stability and promotes aggregation.
RESUMO
Liver regeneration following injury aids the restoration of liver mass and the recovery of liver function. In the present study we investigated the contribution of megakaryocytic leukemia 1 (MKL1), a transcriptional modulator, to liver regeneration. We report that both MKL1 expression and its nuclear translocation correlated with hepatocyte proliferation in cell and animal models of liver regeneration and in liver failure patients. Mice with MKL1 deletion exhibited defective regenerative response in the liver. Transcriptomic analysis revealed that MKL1 interacted with E2F1 to program pro-regenerative transcription. MAPKAPK2 mediated phosphorylation primed MKL1 for its interaction with E2F1. Of interest, phospholipase d2 promoted MKL1 nuclear accumulation and liver regeneration by catalyzing production of phosphatidic acid (PA). PA administration stimulated hepatocyte proliferation and enhanced survival in a MKL1-dependent manner in a pre-clinical model of liver failure. Finally, PA levels was detected to be positively correlated with expression of pro-regenerative genes and inversely correlated with liver injury in liver failure patients. In conclusion, our data reveal a novel mechanism whereby MKL1 contributes to liver regeneration. Screening for small-molecule compounds boosting MKL1 activity may be considered as a reasonable approach to treat acute liver failure.
RESUMO
Colorectal cancer (CRC) is among the most diagnosed malignancies worldwide, and it is also the second leading cause of cancer-related deaths. Despite recent progress in screening programs, noninvasive accurate biomarkers are still needed in the CRC field. In this study, we evaluated and compared the urinary proteomic profiles of patients with colorectal adenocarcinoma and patients without cancer, aiming to identify potential biomarker proteins. Urine samples were collected from 9 patients with CRC and 9 patients with normal colonoscopy results. Mass spectrometry (label-free LC—MS/MS) was used to characterize the proteomic profile of the groups. Ten proteins that were differentially regulated were identified between patients in the experimental group and in the control group, with statistical significance with a p value ≤ 0.05. The only protein that presented upregulation in the CRC group was beta-2-microglobulin (B2M). Subsequent studies are needed to evaluate patients through different analysis approaches to independently verify and validate these biomarker candidates in a larger cohort sample. (AU)

RESUMO
Abstract This meta-research aimed to provide an overview of the methodological quality and risk of bias of network meta-analyses (NMA) in dentistry. Searches for NMA of randomized clinical trials with clinical outcomes in dentistry were performed in databases up to January 2022. Two reviewers independently screened titles/abstracts, selected full texts, and extracted the data. The adherence to PRISMA-NMA reporting guideline, the AMSTAR-2 methodological quality tool, and the ROBIS risk of bias tool were assessed in the studies. Correlation between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results was also investigated. Sixty-two NMA studies were included and presented varied methodological quality. According to AMSTAR-2, half of the NMA presented moderate quality (n = 32; 51.6%). The adherence to PRISMA-NMA also varied. Only 36 studies (58.1%) prospectively registered the protocol. Other issues lacking of reporting were data related were data related to the NMA geometry and the assessment of results consistency, and the evaluation of risk of bias across the studies. ROBIS assessment showed a high risk of bias mainly for domains 1 (study eligibility criteria) and 2 (identification and selection of studies). Correlation coefficients between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results showed moderate correlation (rho < 0.6). Overall, NMA studies in dentistry were of moderate quality and at high risk of bias in several domains, especially study selection. Future reviews should be better planned and conducted and have higher compliance with reporting and quality assessment tools.

RESUMO
Quantitative systems pharmacology (QSP) modeling is an emerging computational medicine approach with growing applications and significance in modern drug development. QSP models are generally formulated based on multiscale disease mechanisms and drug-target interactions, which makes them capable of integrating multimodal data from the preclinical and clinical space. This also enables them to generate quantitative characterization of the dynamic disease progression as well as high-throughput predictions of drug-induced efficacy and toxicity signals. Therefore, QSP modeling and model-based virtual clinical trials have been widely implemented to guide drug development, in scenarios such as target identification and assessment, clinical trial design, evaluation of combination therapy and biomarkers, and personalized medicine. In US and Europe, QSP modeling has been developing rapidly in the past 10 years and is now an integral part of the model-informed drug development paradigm; however, in China it is still a nascent field. Here we will present a comprehensive review of the recent advancements of QSP and its impact in modern drug development through a number of case studies. This review will provide guidance for the future drug development efforts and the growth of QSP practice in China.
RESUMO

We should strengthen the main position of independent innovation of orthopedics new technology, materials and instruments, implement the strategy of combining "import" with China's specific national conditions, and use Chinese and western, strive to solve the problem of transformation of scientific research results, accelerate the process of localization replacement, so that the innovation transformation results in the land of China.
RESUMO
It is known that SMAD specific E3 ubiquitin protein ligase 1 (SMURF1) mediates autophagy through its E3 ubiquitin ligase activity, but the ubiquitinated substrates of SMURF1 need to be further explored. In this paper, the interacting proteins of SMURF1 in THP-1 cells were captured and identified by co-immunoprecipitation (Co-IP) combined with mass spectrometry. It was found that SMURF1 could physically bind to 222 proteins in THP-1 cells, and Adenosine deaminase acting on RNA 1 (ADAR1) had a higher peptide binding score. SMURF1 overexpression vectors were constructed and transfected into HEK-293T cells, then Co-IP and Western blotting assays verified the interaction between exogenous SMURF1 and endogenous ADAR1. qRT-PCR and Western blotting assays were carried out after transfecting SMURF1 overexpression vectors in HEK-293T cells, which identified that overexpression of SMURF1 attenuated the protein levels of ADAR1 (P<0. 05). However, there was no significant difference in the mRNA level of ADAR1. HEK-293T cells with normal and overexpressing SMURF1 were treated with cycloheximide (CHX), respectively, and Western blotting assays showed a shortened half-life of ADAR1 after overexpression of SMURF1 (P < 0. 05). Furthermore, overexpression of SMURF1 increased the polyubiquitination level of ADAR1 as detected by Co-IP and Western blot (P<0. 05). After the proteasome inhibitor (MG132) treatment, the Western blotting assay was performed to demonstrate that the negative regulatory effect of SMURF1 on ADAR1 was weakened after the proteasome degradation pathway was attenuated (P<0. 05). This study shows that SMURF1 interacts with ADAR1, catalyzes the polyubiquitination of ADAR1 and mediates its degradation through the proteasome pathway, which provides a theoretical basis for exploring the various biological functions of SMURF1 by affecting the stability of ADAR1.

RESUMO
Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.
RESUMO
Neurodegenerative diseases (NDs) have become a significant threat to an aging human society. Numerous studies have been conducted in the past decades to clarify their pathologic mechanisms and search for reliable biomarkers. Magnetic resonance imaging (MRI) is a powerful tool for investigating structural and functional brain alterations in NDs. With the advantages of being non-invasive and non-radioactive, it has been frequently used in both animal research and large-scale clinical investigations. MRI may serve as a bridge connecting micro- and macro-level analysis and promoting bench-to-bed translational research. Nevertheless, due to the abundance and complexity of MRI techniques, exploiting their potential is not always straightforward. This review aims to briefly introduce research progress in clinical imaging studies and discuss possible strategies for applying MRI in translational ND research.

As a liver disease with the most complex clinical phenotype, drug-induced liver injury (DILI) poses great challenges in diagnosis and management in clinical practice. Although guidelines based on the latest research advances can provide clinicians with guidance on the identification, diagnosis, and management of DILI, the overall level of evidence in this field is relatively low and high-level evidence is limited. Therefore, we should interpret guidelines with caution and look forward to more clinical and translational research to address the huge unmet clinical needs in DILI.

RESUMO O objetivo deste estudo foi identificar como a Inteligência Artificial (IA) vem sendo utilizada para a pesquisa translacional no contexto da Covid-19. Foi realizada uma revisão rápida para identificar o uso de técnicas de IA na translação de tecnologias para o enfrentamento da Covid-19. Empregou-se estratégia de busca com base em termos MeSH e seus respectivos sinônimos em sete bases de dados. Dos 59 artigos identificados, oito foram incluídos. Foram identificadas 11 experiências que usaram IA para a pesquisa translacional em Covid-19: predição de eficácia medicamentosa; predição de patogenicidade do Sars-CoV-2; diagnóstico de imagem para Covid-19; predição de incidência de Covid-19; estimativas de impacto da Covid-19 na sociedade; automatização de sanitização de ambientes hospitalares e clínicos; rastreio de pessoas infectadas e possivelmente infectadas; monitoramento do uso de máscaras; predição de gravidade de pacientes; estratificação de risco do paciente; e predição de recursos hospitalares. A pesquisa translacional pode ajudar no desenvolvimento produtivo e industrial em saúde, especialmente quando apoiada em métodos de IA, uma ferramenta cada vez mais importante, sobretudo quando se discute a Quarta Revolução Industrial e suas aplicações na saúde.
ABSTRACT The objective of this study was to identify how Artificial Intelligence (AI) has been used for translational research in the context of COVID-19. A rapid review was carried out to identify the use of AI techniques in the translation of technologies to face COVID-19. A search strategy was used based on MeSH terms and their respective synonyms in seven databases. Of the 59 articles identified, eight were included. We identified 11 experiments that used AI for translational research in Covid-19: prediction of drug efficacy; predicting the pathogenicity of SARS-CoV-2; imaging diagnosis for COVID-19; predicting the incidence of COVID-19; estimates of the impact of COVID-19 on society; automation of sanitizing hospital and clinical environments; screening of infected and possibly infected people; monitoring the use of masks; prediction of patient severity; patient risk stratification; and prediction of hospital resources. Translational research can help in productive and industrial development in health, especially when supported by AI methods, an increasingly important tool, especially when discussing the Fourth Industrial Revolution and its applications in health.
RESUMO
Aim: This study analyzed public procurements for different endodontic materials used in the Brazilian public health system and evaluated the variables related to their cost. Methods: A time-series study was performed by screening materials for endodontic application in the public Brazilian Databank of Healthcare Prices from 2010 to 2019. Data were categorized according to material composition and clinical application. The collated variables were used in a multiple linear regression model to predict the impact of unit price in procurement processes. Results: A total of 5,973 procurement processes (1,524,693 items) were evaluated. Calcium hydroxides were found in 79% of the observations (4,669 processes). Prices drop each year by US$1.87 while MTAs and epoxy resins are increasingly purchased at higher prices (US$50.87; US$67.69, respectively). The microregion, the procurement modality, and the type of institution had no influence on unit prices in the adjusted model (p > 0.05). Conclusions: Calcium hydroxide-based materials were the cheapest and most frequently purchased endodontic materials in the public health care system. Novel formulations are being implemented into clinical practice over time and their cost may be a barrier to the broad application of materials such as MTAs, despite their effectiveness
