A Novel Brazilian Isolate Expands the Genomic and Phenotypic Characterization of Chlorovirus americanus

A novel chlorovirus was isolated from a freshwater sample collected from a Brazilian urban lake. Members of the family Phycodnaviridae, the chloroviruses have large linear dsDNA genomes (285–410 kbp) that encode hundreds of proteins and tRNAs. Despite their ecological and evoluti...

Recycled Co(OH)₂ from spent LiCoO₂ cathodes as a low-cost graphite-based composite electrode for the oxygen evolution reaction

Abstract The conversion of materials recovered from spent lithium-ion batteries into functional electrodes provides a promising strategy for integrating waste valorization with electrochemical energy conversion. In this work, cobalt was recovered from spent LiCoO₂ cathodes with a...

Homogeneous Ethanol CuCl 2 /TMEDA/TEMPO System Mimicking Laccase/TEMPO for the Catalytic Aerobic Oxidation of Primary Furyl, Allyl and Benzyl Alcohols

ABSTRACT We report herein a homogeneous ethanol CuCl 2 /TMEDA/TEMPO system for the catalytic aerobic oxidation of primary furyl, allyl, and benzyl alcohols. Under the established protocol, the reactions occur under mild conditions (25°C, open‐air atmosphere), requiring low cataly...

Isolated physical activity programs during pregnancy and postpartum: Meta-analysis of randomized trials with usual-care controls on depressive and anxiety symptoms

OBJECTIVE: This study systematically evaluated the isolated effects of physical activity on depressive and anxiety symptoms during the perinatal period. METHODS: This systematic review was registered in PROSPERO (CRD42022301284) and conducted in accordance with the Cochrane Handb...

Remote sensing for monitoring and managing Eichhornia crassipes: a review of methods, applications, and decision-support frameworks

Abstract Eichhornia crassipes (water hyacinth) is among the world’s most aggressive aquatic invasive plants, with severe ecological and socioeconomic impacts on freshwater ecosystems. Over the last two decades, remote sensing has emerged as a critical tool for monitoring its spre...

Administration of nebivolol after subcutaneous ovarian autotransplantation improves neoangiogenesis, follicular survival, and growth in mice

Context As ovarian transplantation is performed without blood vessel anastomosis, its main limitation is ischemia. Nitric oxide (NO) has pro-angiogenic and antiapoptotic effects, and nebivolol, a selective β1-blocker with NO-inducing activity, may be a potential drug to improve g...

A Generalization of Marstrand’s Theorem and Some Geometric Applications

Abstract In this paper we prove using quite elementary methods, with a combinatorial nature, two general results related to Marstrand’s projection theorem in a quite general formulation over metric spaces under a suitable transversality condition (the “projections" are in princip...

Recent Advances in Synthesis and Characterization of Niobium Catalysts: A Review

Niobium-based catalysts have emerged as highly adaptable materials for reactions under heterogeneous conditions, owing to significant advances achieved in synthetic methodologies and characterization strategies. In this review, special attention was paid to analyzing the main met...
