Context: Advanced heart failure (AHF) poses a global challenge, where heart transplantation is a treatment option but limited by donor scarcity. Proposal: This study aims to enhance the performance of ventricular assist devices (VADs) in the face of adverse events (AEs) using a resilience-based approach. The objective is to develop a method for integrating resilience attributes into VAD control systems, employing dynamic risk analysis and control strategies. Results: The outcomes include a resilient control architecture enabling anticipatory, regenerative, and degenerative actions in response to AEs. A method of applied resilience (MAR) based on dynamic risk management and resilience attribute analysis was proposed. Conclusion: Dynamic integration between medical and technical teams allows continuous adaptation of control systems to meet patient needs over time, improving reliability, safety, and effectiveness of VADs, with potential positive impact on the health of heart failure patients.

Dear editor:We sincerely thank Matthew *** for his insightful commentary1 on our recent publication in the journal of Sport and Health Science.2 Clarkson's pioneering work in the development and application of blood flow restriction (BFR) exercise protocols has undeniably laid the groundwork for subsequent investigations in this field,including our own.(3-6)His commentary not only highlights the relevance and timeliness of our study but also offers valuable perspectives on refining safety considerations for intradialytic BFR exercise among hemodialysis patients.

Gain of transcription factor binding sites is associated to changes in the expression signature of human brain and testis and is correlated to genes with higher expression breadth

作者： Vandeclécio lira da Silva André Mauricio Ribeiro dos santos Wilfredo Blanco Sandro josé de Souza Bioinformatics Multidisciplinary Environment (BioME) Universidade Federal do Rio Grande do Norte (UFRN) Programa de Pós-Gradua??o em Genética e Biologia Molecular (PPGBM) Universidade Federal do Pará (UFPA) Department of Computer Science Universidade Estadual do Rio Grande do Norte (UERN) Brain Institute Universidade Federal do Rio Grande do Norte (UFRN)

The gain of transcription factor binding sites(TFBS) is believed to represent one of the major causes of biological *** we used strategies based on comparative genomics to identify 21,822 TFBS specific to the human lineage(TFBS-HS),when compared to chimpanzee and gorilla genomes. More than 40%(9,206) of these TFBS-HS are in the vicinity of 1,283 genes.A comparison of the expression pattern of these genes and the corresponding orthologs in chimpanzee and gorilla identified genes differentially expressed in human tissues. These genes show a more divergent expression pattern in the human testis and brain, suggesting a role for positive selection in the fixation of TFBS gains. Genes associated with TFBS-HS were enriched in gene ontology categories related to transcriptional regulation, signaling, differentiation/development and nervous ***, genes associated with TFBS-HS present a higher expression breadth when compared to genes in general. This biased distribution is due to a preferential gain of TFBS in genes with higher expression breadth rather than a shift in the expression pattern after the gain of TFBS.
