The rate of glucose metabolism sets the cell morphology across yeast strains and species.

Yeasts are a diverse group of unicellular fungi that have developed a wide array of phenotypes and traits over 400 million years of evolution. However, we still lack an understanding of the biological principles governing the range of cell morphologies, metabolic modes, and reproductive strategies yeasts display. In this study, we explored the relationship between cell morphology and metabolism in sixteen yeast strains across eleven species.

Short-term negative effects of seawater acidification on the rhodolith holobionts metatranscriptome.

Distribution of strontium isotopes (Sr/Sr) in surface waters of the Amazon basin: A basis for studies on provenance.

The Sr/Sr isotope ratio has been widely used as an indicator of provenance and migration of aquatic animals, and has applications in other areas such as in environmental and forensic studies. However, the modeling of the spatial distribution in the Amazon basin is still incipient, preventing large-scale applications. In this study, we present a baseline of the Sr/Sr isotope ratio in surface waters of the Amazon basin to infer the provenance and migration patterns of fish.

Online ensemble model compression for nonstationary data stream learning.

Learning from data streams that emerge from nonstationary environments has many real-world applications and poses various challenges. A key characteristic of such a task is the varying nature of the underlying data distributions over time (concept drifts). However, the most common type of data stream learning approach are ensemble approaches, which involve the training of multiple base learners.

Physicochemical analyses revealed significant differences among the treatments, with thermal pasteurization maintaining stability for up to 14 days, pasteurization with additives for up to 28 days, and ultrasound treatment for up to 21 days.

Sodium fluorescein video Angiography-Assisted clipping of intracranial Aneurysms: A systematic review and Meta-Analysis.

Objectives: Ensuring aneurysm exclusion while maintaining vessel patency is crucial during intracranial aneurysm clipping. Although digital subtraction angiography (DSA) is the gold standard for intraoperative vascular imaging, some centers have reported using fluorescein sodium video angiography (FNa-VA). However, a synthesis of these findings is still lacking.

Focus on brown dog tick-transmitted Rocky Mountain spotted fever in dogs and people: shared threats and solutions.

Rocky Mountain spotted fever (RMSF) kills people and dogs in rural communities throughout the Americas and in urban epidemics in Brazil and Mexico. The companion Currents in One Health by Foley et al, AJVR , March 2025, addresses the urban ecology of this devastating disease across the Americas. Cases acquired from Dermacentor spp ticks are sylvatic and sporadic, in contrast with peridomestic cases from Rhipicephalus sanguineus sensu lato, which relies on dogs as hosts.

Plasma phosphorylated tau217 strongly associates with memory deficits in the Alzheimer's disease spectrum.

Plasma phosphorylated tau biomarkers open unprecedented opportunities for identifying carriers of Alzheimer's disease pathophysiology in early disease stages using minimally invasive techniques. Plasma p-tau biomarkers are believed to reflect tau phosphorylation and secretion. However, it remains unclear to what extent the magnitude of plasma p-tau abnormalities reflects neuronal network disturbance in the form of cognitive impairment.

Study of the behaviour of cations in leaching of NCA lithium-ion batteries by electrodialysis.

End-of-life lithium-ion batteries (LIBs) present an opportunity to generate a circular economy through recycling. One of the techniques that can contribute to the purification of leached batteries is electrodialysis. In this work, we present a study of current variation in relation to monovalent (Li), divalent (Ni and Co) and trivalent (Al) cations from the synthetic solution of an NCA-type lithium-ion battery leachate, using electrodialysis membranes (HDX-100 and HDX-200) at three different current densities (12.

Effects of CPAP on Central and Peripheral Blood Pressure in Patients with Uncontrolled Hypertension and OSA: The MORPHEOS Trial.

Rationale: Previous studies evaluating the effect of continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) on blood pressure (BP) showed variable results. Moreover, several studies recruited patients with normal or controlled BP, and compliance to antihypertensive drugs was not monitored. In addition, very few studies investigated central BP in this scenario.
