Molecular mechanisms of lipid metabolism abnormalities driving sepsis and atrial fibrillation: A Systematic study based on bioinformatics and machine learning

by Changze Ou, Haidong Yu, Binbin Chen, Huajun Long

Background

Sepsis and atrial fibrillation are complex, life-threatening medical conditions affecting approximately 49 million individuals globally, characterized by exceptionally high mortality rates. Lipid metabolism abnormalities play a critical role in the pathogenesis of these diseases, yet their underlying molecular mechanisms remain incompletely understood.

Objective

This innovative study systematically investigates the shared... Читать дальше...

Blood draw site and blood matrix influence mineral assessment

by Mikail G. Alejandro, Kathleen Schultz, David W. Killilea

Circulating mineral concentrations are used to assess nutritional status or as markers for clinical conditions, but the quality of these measurements depends on the methods used for blood processing. Since the procedures for measuring mineral levels in blood are not standardized, discrepancies in sampling may influence the analytical results. We previously reported that zinc content in blood samples showed significant variation depending... Читать дальше...

Rhodnius prolixus impairs Trypanosoma cruzi growth through cold-seeking behavioral thermoregulation

by Henri Loshouarn, Alessandra A. Guarneri

Chagas disease, caused by the parasite Trypanosoma cruzi, is a major neglected tropical disease affecting 6–7 million people worldwide. Rhodnius prolixus, one of the most important vectors of Chagas disease in Latin America, is known to be highly sensitive to environmental temperature, which influences both its biology and parasite development. However, few studies have investigated how this vector behaviorally modulates the effects of temperature by shifting their thermopreference... Читать дальше...

Centromeres in budding yeasts are conserved in chromosomal location but not in structure

by Conor Hession, Kevin P. Byrne, Kenneth H. Wolfe, Geraldine Butler

The budding yeast Saccharomyces cerevisiae has ‘point’ centromeres, which are much smaller and simpler than centromeres of most other eukaryotes and have a defined DNA sequence. Other yeast taxa have different and highly diverse centromere structures, but a clear picture of how yeast centromeres have evolved is lacking. Here, we investigated nine yeast species in two taxonomic orders that are close outgroups to S. cerevisiae. Читать дальше...

Whom do we prefer to learn from in observational reinforcement learning?

by Gota Morishita, Carsten Murawski, Nitin Yadav, Shinsuke Suzuki

Learning by observing others’ experiences is a hallmark of human intelligence. While the neurocomputational mechanisms underlying observational learning are well understood, less is known about whom people prefer to learn from in the context of observational learning. One hypothesis posits that learners prefer individuals who exhibit a high degree of decision noise, ‘free riding’ on the costly exploration of others. An alternative... Читать дальше...

Learning structured population models from data with WSINDy

by Rainey Lyons, Vanja Dukic, David M. Bortz

Characteristics of individuals in a population, such as age and size, play a key role in determining how populations change over time. In contexts of population dynamics, identifying effective model features, such as fecundity and mortality rates, is generally a complex and computationally intensive process, especially when the dynamics are heterogeneous across the population. In this work, we propose a Weak form Scientific Machine Learning-based... Читать дальше...

From pipeline to network: We need to redefine scientific success

by Alexandra A.-T. Weber

The traditional pipeline view of academia no longer reflects the reality of scientific careers. Reframing success as a network of paths recognizes excellence in its many forms, fostering a more inclusive, resilient, and socially engaged research culture.

The deubiquitinating enzyme Cezanne stabilizes BRCA1 by counteracting APC/C and Ube2S-dependent Lys11-linked ubiquitination

by Longqiang Wang, Xiao Wu, Atanu Paul, Jun Yao, Bin Wang

The breast and ovarian tumor suppressor BRCA1 is a cell cycle-regulated protein and tumors with reduced BRCA1 protein level may share molecular features of BRCA1-mutant tumor and respond to PARPi therapy. Here, we identify that BRCA1 protein stability is controlled through ubiquitin lysine 11 (K11)-linkage modification under the regulation of Cezanne deubiquitinating enzyme, APC/C E3 ligase, and Ube2S E2 conjugating enzyme in a cell cycle-dependent manner.

A new path to spillover: MHC-II entry of influenza A viruses

by Silke Stertz, Umut Karakus

Zoonotic spillover of influenza A viruses represents a threat to human health. Emerging research suggests that some influenza A viruses can enter host cells via MHC-II across species, potentially increasing spillover risk. Spillover of influenza A viruses from animals to humans represents a threat to our health. This Perspective discusses emerging research that suggests some influenza A viruses can enter host cells via MHC-II across species, reflecting on the... Читать дальше...
