Seasonal and intracanopy shifts in the fates of absorbed photons in central Amazonian forests: implications for leaf fluorescence and photosynthesis. [PDF]
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.

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 ...

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
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 ...

Lupeol as a Potential Inhibitor of NorA Efflux Pumps in Staphylococcus aureus: In Silico and In Vitro Evidence. [PDF]
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 ...

Currently, the minimal functional adrenal remnant size, and the impact of intraoperative imaging technologies on remnant function after partial adrenalectomy, is unknown. In the present experimental study, intraoperative perfusion assessment, using quantitative fluorescence imaging, confocal laser endomicroscopy and contrast‐enhanced CT, enabled ...

Diagnóstico por Fluorescencia en Tumores Vesicales [PDF]
Tanto el exceso como la falta de luz pueden provocar ceguera. La cistoscopia de fluorescencia, sin cegarnos, ni dejarnos deslumbrar por falsas expectativas, podemos decir que nos desvela muchas lesiones, inaparentes a la luz blanca. La aprobacion hace unos seis meses de la utilizacion del hexaminolevulinato (HEXVIX)R con fines diagnosticos en Espana ...

Role of circulating fibrocytes in the diagnosis of acute appendicitis
The circulating fibrocyte percentage is increased in patients with acute appendicitis. This may improve diagnostics, and reduce unnecessary radiation exposure and surgical operations. Circulating fibrocyte percentage may help in diagnosis of acute appendicitis. Background Improved diagnostic biomarkers are required for acute appendicitis.

Abstract Despite current central nervous system‐directed therapies for childhood B‐cell precursor acute lymphoblastic leukaemia, relapse at this anatomical site still remains a challenging issue. Few reports have addressed the study of the specific cellular microenvironments which can promote the survival, quiescence, and therefore chemoresistance of B‐
