A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

Presence of enteric viruses, bioaccumulation and stability in Anomalocardia brasiliana clams (Gmelin, 1791)

open access: yes, 2018
Bivalve mollusks are filter feeders and may accumulate human pathogens in their tissues. Many studies demonstrated human diseases associated with bivalve consumption, especially oysters.

Blood indices of sheep fed with ensiled signal grass (Brachiaria decumbens)

open access: yesNew Zealand Journal of Agricultural Research, Volume 68, Issue 7, Page 1985-2002, December 2025.
ABSTRACT The Brachiaria species, particularly B. decumbens, is a key ruminant feed in the tropics but contains steroidal saponins that may cause toxicity, raising concerns for small ruminant farmers. Eighteen 6‐month‐old sheep were randomly assigned to three treatments over a 90‐day feeding trial: Negative control (fresh P.

Sedimentological and biofabric patterns for hybrid coquina deposits: Insights from wave tank experiments

open access: yesSedimentology, Volume 72, Issue 6, Page 1992-2024, October 2025.
ABSTRACT Hybrid bioclastic/siliciclastic coquinas are sedimentary accumulations typical of coastal‐ and shallow‐water settings, where wave breaking, longshore drift and wave shoaling drive sediment transport and control the final accumulations. These processes resulted in thick packages of sediments, as identified in the Lower Cretaceous depositional ...

Population structure of the bivalve Anomalocardia brasiliana, (Gmelin, 1791) in the semi-arid estuarine region of northeastern Brazil

open access: yesBrazilian Journal of Biology
For several decades, the bivalve mollusk Anomalocardia brasiliana has been extracted in estuarine areas in the semi-arid region of northeastern Brazil. However, information on both dynamics and abundance of their populations are missing. In this context,

A New Insight into the Taxonomy of Pseudo-nitzschia Genus from the Adriatic Sea: Description of P. brasiliana, P. galaxiae, P. hasleana, and P. linea

open access: yesJournal of Marine Science and Engineering, 2023
Marine diatoms of the genus Pseudo-nitzschia are widespread and occur in various environments. About half of the species described today have been shown to be toxic, producing the potent neurotoxin, domoic acid.

Flavonoids as Promising Akt1 Inhibitors in Cancer Medicine: Insights From Molecular Docking, Dynamics, DFT Calculations, and In Vitro Validation

open access: yesCancer Reports, Volume 8, Issue 8, August 2025.
ABSTRACT Background The PI3K/Akt/mTOR signaling pathway is commonly deregulated in different types of cancers, contributing to tumor proliferation, persistence, and resistance to treatment. Akt1, a crucial kinase within this pathway, plays a critical role in tumor progression and the occurrence of therapeutic resistance.

Hermaphroditism among dioecious Tagelus plebeius (Lightfoot, 1786) (Mollusca, Psammobiidae) and Iphigenia brasiliana (Lamarck, 1818) (Mollusca, Donacidae) on the Cachoeira River Estuary, Ilhéus, Bahia, Brazil Hermafroditismo nos moluscos dióicos Tagelus plebeius (Lightfoot, 1786) (Mollusca, Psammobiidae) e Iphigenia brasiliana (Lamarck, 1818) (Mollusca, Donacidae) na região estuarina do Rio Cachoeira, Ilhéus, Bahia, Brasil

open access: yesBrazilian Journal of Biology, 2010
The samples of Tagelus plebeius and Iphigenia brasiliana were manually collected on the Cachoeira River estuary region (Ilhéus, BA, Brazil) between August 2005 and August 2006, with a periodicity of 15 days, with 20 animals collected/sampled, performing ...
