Implementation of a novel in vitro model of infection of reconstituted human epithelium for expression of virulence genes in methicillin-resistant Staphylococcus aureus strains isolated from catheter-related infections in Mexico [PDF]

open access: yes, 2014
BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) are clinically relevant pathogens that cause severe catheter-related nosocomial infections driven by several virulence factors.

Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

open access: yesActa Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as

Schedule‐dependent neuroprotection by pioglitazone in a novel model of α‐synucleinopathy in rats: Integrated behavioural and histological outcomes

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose α‐Synucleinopathies are neurodegenerative disorders characterized by the aggregation and propagation of misfolded α‐synuclein. In Parkinson's disease (PD), the most common α‐synucleinopathy, the progression of motor and nonmotor deficits, and dopaminergic neuron loss, are closely linked to the spreading of misfolded α‐synuclein ...

Who prefers the dark? Daily activity of dung beetles from an Amazonian region

open access: yesEcological Entomology, Volume 51, Issue 3, Page 609-613, June 2026.
Daily activity patterns shape how dung beetle species coexist in Amazonian forests, revealing temporal niches that reduce competition and structure biodiversity. We compared species richness, abundance and assemblage composition of dung beetles sampled during day and night in a conserved terra‐firme forest in the Brazilian Amazon. Although richness and

Effects of soil physical properties on dung beetle assemblages in pasture landscapes of the Brazilian Cerrado

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 2, Page 169-181, May 2026.
We assessed the effect of the type of soil texture (loamy sand and sandy loam) and its physical properties on dung beetle species assemblages in a pastureland region of the Brazilian Cerrado. We found a reduction in the total and paracoprid beetle abundances in loamy sand soil. Furthermore, the increase of soil compaction negatively affected the entire

Life Cycle Plasticity of Colpoda aspera Fed With Petroleum Tolerant Gram‐Positive and Gram‐Negative Bacteria

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Soil recovery after contamination relies on the surviving microbiota to reconstruct microbial food webs. The ciliate Colpoda aspera and Brevundimonas sp., Rhizobium sp1, Rhizobium sp2 (gram‐negative), Bacillus sp1, Bacillus sp2, and Microbacterium sp.(gram‐positive) remain active after pulses of light petroleum contamination.
