Deletion of and genes in serovars induces a comparable immune response to wild-type infection in different chicken lineages.

It was previously reported that utilization of tetrathionate and 1,2-propanediol by spp. through the metabolic pathways encoded by and operons are related to overgrowth and out-competing microbiota in an anaerobic environment. However, recent knowledge demonstrated which strains in the absence of and genes provoke both higher intestinal colonization and spreading bacteria on faeces in relation to their respective wild-type strain, and generate more prominent inflammation as well.

Prevalence of Lp(a) in a real-world Portuguese cohort: implications for cardiovascular risk assessment.

Background: Cardiovascular disease (CVD) is a major cause of mortality worldwide, necessitating more refined strategies for risk assessment. Recently, lipoprotein(a) [Lp(a)] has gained attention for its distinctive role in atherosclerosis, yet its prevalence and impact for cardiovascular risk assessment are not well-documented in the Portuguese population. This study aimed to characterize Lp(a) levels in a real-world Portuguese cohort, investigating its prevalence and association with CVD risk.

Exploring Distinct Second-Order Data Approaches for Thiamine Quantification via Carbon Dot/Silver Nanoparticle FRET Reversion.

Accurate and selective monitoring of thiamine levels in multivitamin supplements is essential for preventing deficiencies and ensuring product quality. To achieve this, a Förster resonance energy transfer (FRET) system using carbon dots (CDs) as energy donors and citrate-stabilized silver nanoparticles (AgNPs) as energy acceptors was developed. The aqueous synthesis of AgNPs using microwave irradiation was optimized to obtain efficient plasmonic nanoparticles for FRET applications, targeting maximal absorbance intensity, stability, and wavelength alignment.

Ability of brazilian Bothrops-Lachesis-Crotalus antivenom in neutralizing some biological activities of Crotalus durissus ruruima rattlesnake venom.

We evaluated the efficacy of freeze-dried Bothrops-Lachesis-Crotalus antivenom and liquid Crotalus antivenoms to neutralize Crotalus durissus ruruima (Cdr) venom (Roraima, Brazil) comparing with C. d. terrificus (Cdt) venom.

Ectopic expression of a truncated NLR gene from wild enhances resistance to .

causes devastating vascular wilt diseases in numerous crop species, resulting in substantial yield losses. The - (FOC) model system enables the identification of meaningful genotype-phenotype correlations and was applied in this study to evaluate the effects of overexpressing an NLR gene () from against pathogen infection. overexpression (OE) lines exhibited enhanced resistance to FOC without any discernible phenotype penalties.
