Natural history of the hyperdominant tree, Pentaclethra macroloba (Willd.) Kuntze, in the Amazon River estuary.

Pentaclethra macroloba is a hyperdominant species with multiple uses in the Amazon. This species tolerates varying flood amplitudes, however the effect of flood topographic gradient on its ecophysiology remains unclear. We want to know if individuals from the high (10 trees) and low (20 trees) várzea show distinct phenological patterns as a function of the flood gradient, as well as their colonization strategies and their seed predators.

Calcium-Binding Proteins in the Autistic Brain-Potential Links to Symptom Development.

Autism spectrum disorder (ASD) is a complex challenge, influenced by genetic and environmental factors. This review focuses on the proteins calbindin (CB), calretinin (CR) and parvalbumin (PV) in the context of ASD, exploring their clinical correlations and providing a deeper understanding of the spectrum. In addition, we seek to understand the role of these proteins in GABAergic regulation and their implication in the pathophysiology of ASD.

Effect of Mn(II) and Co(II) on Anti- Metabolite Production by sp. an Endophyte Isolated from (Plantaginaceae).

: This study evaluates the effect of Mn(II) and Co(II) ions on the production of anti- metabolites by the endophytic fungus Aspergillus sp., isolated from . The objective was to identify metal-induced secondary metabolites with antifungal potential against drug-resistant species.

Nuclear morphology, chromatin compaction, and epigenetic changes in lymphocytes of dogs infected with Ehrlichia canis.

Canine monocytic ehrlichiosis (CME), induced by Ehrlichia canis, is an important infectious disease in dogs, characterized by various clinical signs and consequent immune dysfunction. This study aimed to characterize nuclear morphology, chromatin compaction, histone H3 acetylation, and DNA methylation in lymphocytes from dogs naturally infected with E. canis, compared with healthy controls.

Hyperresponsiveness of Corticoid-Resistant Th17/Tc-17 Cells to TLR-2 and TLR-4 Ligands is a Feature of Multiple Sclerosis Patients at Higher Risk of Therapy Failure.

Purpose: The presence of T cells expressing TLR-2 and TLR-4 has been associated with relapsing-remitting multiple sclerosis (RRMS) pathogenesis. Here, we evaluated whether the effectiveness of DMT in controlling clinical activity of the disease would be associated with modulation of proportion of TLRs T cells.

Patients And Methods: Whole peripheral blood mononuclear cells, purified CD4 and CD8 T cells from RRMS patients were cultured with different stimuli.
