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

New Phytol
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
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 ...

FINDeM: A CRISPR‐based, molecular method for rapid, inexpensive and field‐deployable organism detection

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 ...

Aging is accompanied by T‐cell stiffening and reduced interstitial migration through dysfunctional nuclear organization

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 ...

Intraoperative imaging for remnant viability assessment in bilateral posterior retroperitoneoscopic partial adrenalectomy in an experimental model

BJS (British Journal of Surgery), Volume 107, Issue 13, Page 1780-1790, December 2020., 2020
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 ...

Role of circulating fibrocytes in the diagnosis of acute appendicitis

BJS Open, Volume 4, Issue 6, Page 1256-1265, December 2020., 2020
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.

The choroid plexus stroma constitutes a sanctuary for paediatric B‐cell precursor acute lymphoblastic leukaemia in the central nervous system

The Journal of Pathology, Volume 252, Issue 2, Page 189-200, October 2020., 2020
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‐

Direct and indirect immunofluorescence [PDF]

, 2010
A imunofluorescência é um valioso instrumento auxiliar no diagnóstico das dermatoses bolhosas autoimunes e desordens inflamatórias, uma vez que seus achados clínicos e histopatológicos podem não ser determinantes.
