Seasonal and intracanopy shifts in the fates of absorbed photons in central Amazonian forests: implications for leaf fluorescence and photosynthesis [PDF]
New Phytologist, Volume 248, Issue 1, Page 76-91, October 2025.Summary Recent studies have shown a linear relationship between solar‐induced Chl fluorescence (SIF) and gross primary productivity (GPP) at large scales. However, this relationship diverges at finer leaf scales, particularly in tropical forests with complex canopy structures.

Lupeol as a Potential Inhibitor of NorA Efflux Pumps in Staphylococcus aureus: In Silico and In Vitro Evidence [PDF]
ChemistryOpen, Volume 14, Issue 11, November 2025.Antimicrobial resistance remains one of the major challenges to global public health, compromising the effectiveness of treatments and contributing to increased morbidity and mortality associated with bacterial infections. Among the mechanisms involved, efflux pumps—such as NorA, expressed in resistant strains of Staphylococcus aureus—are particularly ...

Fluorescencia de los Tejidos Queratinosos [PDF]
International Journal of Morphology, 2012 Utilizando una tecnica de fluorescencia, registramos mapas de los fluoroforos presentes en varios tipos de tejidos queratinosos. Descubrimos que la fluorescencia de todas las muestras analizadas tienen rasgos en comun. Observamos el aminoacido triptofano en todos los tejidos.

Methods in Ecology and Evolution, Volume 14, Issue 12, Page 3055-3067, December 2023., 2023 Abstract The field of ecology has undergone a molecular revolution, with researchers increasingly relying on DNA‐based methods for organism detection. Unfortunately, these techniques often require expensive equipment, dedicated laboratory spaces and specialized training in molecular and computational techniques; limitations that may exclude field ...

Immunology, Volume 167, Issue 4, Page 622-639, December 2022., 2022 Proposed biophysical model. Abstract Age‐associated changes in T‐cell function play a central role in immunosenescence. The role of aging in the decreased T‐cell repertoire, primarily because of thymic involution, has been extensively studied. However, increasing evidence indicates that aging also modulates the mechanical properties of cells and the ...

A novel fluorescence and DNA combination for versatile, long‐term marking of mosquitoes
Methods in Ecology and Evolution, Volume 12, Issue 6, Page 1008-1016, June 2021., 2021 Abstract Current mark–release–recapture methodologies are limited in their ability to address complex problems in vector biology, such as studying multiple groups overlapping in space and time. Additionally, limited mark retention, reduced post‐marking survival and the large effort in marking, collection and recapture all complicate effective insect ...
