Freshwater and Sediment Host Distinct Yet Overlapping Microeukaryotic Communities, With Sediment Communities Less Impacted by Treated Wastewater

Journal of Eukaryotic Microbiology, Volume 73, Issue 2, March/April 2026.
ABSTRACT Freshwater and sediment environments host diverse microeukaryotic communities that differ in structure and composition, yet exhibit taxonomic overlap. Using 18S V9 rRNA gene sequencing, we compared communities from these habitats in controlled 10‐day mesocosm experiments, examining diversity, overlap, and responses to treated wastewater (TWW).

Monodentate Phosphine Modulation in Cyclometallated Platinum(II) Complexes for Antileishmanial, Antiviral, and Antitumor Applications

ChemMedChem, Volume 21, Issue 4, 25 February 2026.
Schematic representation depicting the influence of phosphine ligand identity on the biological and physicochemical characteristics of Pt(II) complexes: PTA promotes antileishmanial activity, PPh2(Php–COOH) strengthens antiviral activity, and TCEP enhances fluorescence.

Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Selective Effects of Environmental Conditions and Protection Levels on Herbivorous Fish Functions in the Largest South Atlantic Reef Complex

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Herbivorous fish are key components in maintaining functionality in reef environments; however, this group is widely threatened by overfishing and habitat degradation. Investigating the main factors determining the structure of herbivorous fish becomes paramount to defining management strategies amid anthropogenic impacts. This study evaluated

Persistent Infections by Leishmania (Viannia) braziliensis

, 1997
Here we review the phenomenon of persistency in Leishmania (Viannia) braziliensis infections. In other Leishmania species where appropriate animal models exist, considerable advances in the understanding of basic immunologic mechanisms of persistency ...

Genotypic Differences among Isolates of L. Braziliensis and Host Factors in The Pathogenesis of Disseminated Leishmaniasis

, 2020
Abstract Disseminated Leishmaniasis (DL) is an emerging and severe form of Leishmania braziliensis infection defined by the presence of 10 and up to more than 1,000 skin lesions. The mechanisms underlying parasite dissemination remain unknown. Genotypic differences among species of L.
