In Situ Measurements of Light Diffusion in an Optically Dense Atomic Ensemble.

This study introduces a novel method to investigate in situ light transport within optically thick ensembles of cold atoms, exploiting the internal structure of alkaline-earth metals. A method for creating an optical excitation at the center of a large atomic cloud is demonstrated, and we observe its propagation through multiple scattering events. In conditions where the cloud size is significantly larger than the transport mean free path, a diffusive regime is identified.

Spatial distribution and sequential sampling plan for Oligonychus punicae (Acari: Trombidiformes: Tetranychidae) on grapevine.

Sequential sampling plans are employed for the rapid characterization of infestations to facilitate decision-making. This study aimed to (i) investigate the spatial distribution of Oligonychus punicae (Hirst) in grapevine crops, (ii) determine the most representative branch, leaf, and leaf region for monitoring, and (iii) develop a sequential sampling plan for decision-making to control O. punicae in the table grape varieties Arra 15, BRS Vitória, Cotton Candy, Sugar Crisp, and Timpson at different phenological stages.

Epidemiological landscape of tongue cancer in younger patients in a National Cancer Center in Brazil.

This study investigates the changing epidemiological profile of tongue squamous cell carcinoma (SCC) to young patients, highlighting its rising incidence among non-traditional risk groups. A retrospective descriptive study was conducted, covering data from medical records between 2000 and 2012. Patients were categorised into two age groups (≤ 40 years; 41-50 years).

Fibromyalgia comorbidity in Systemic Lupus Erythematosus patients: assessing impact on quality of life.

Introduction: The prevalence of Fibromyalgia in patients with Systemic Lupus Erythematosus (SLE) is significantly higher compared to the general population. Despite this frequent association, Fibromyalgia remains underdiagnosed and consequently inadequately treated, negatively affecting the quality of life of these patients.

Objective: This study aims to evaluate the occurrence of Fibromyalgia and its impact on the quality of life of Brazilian patients with SLE treated at a University Hospital in the state of Paraiba.

Analysis of the Sensitivity and Specificity of Histopathological Findings for Diagnosing Lupus Nephritis.

Background: Since the introduction of the SLICC criteria in 2012, biopsy-proven lupus nephritis (LN) has been the only independent diagnostic criterion for systemic lupus erythematosus (SLE). This was reaffirmed by the EULAR/ACR in 2019, emphasizing the importance of renal biopsy in LN. However, the current classification lacks specific histopathological criteria for defining LN.
