This study presents unpublished data on the chlorogenic acid and caffeic acid content in fruits. Sixty-four fruits consumed in Brazil, most of which were produced domestically, were evaluated based on their levels of 3-caffeoylquinic acid, 4-caffeoylquinic acid, 5-caffeoylquinic acid, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid and caffeic acid. The study investigated 15 fruits that have not been reported in the literature in relation to these compounds, including several native species. The highest concentration of mono-caffeoylquinic acid was observed in strawberry, cherry, bilberry, quince and mulberry, while the dicaffeoylquinic acid was present with highest concentration in kumquat, passion fruit and sweet granadilla. Regarding caffeic acid, the highest content was found in bilberry and yellow pitaya. Considering the sum of the concentrations of these compounds, quince, cherry, bilberry, mulberry and sweet granadilla were exceptional, with concentrations between 200.0 and 569.7 mg kg.

The aggregation of proteins, peptides and amino acids has been a keen subject of interest owing to their implications in metabolic disorders. In this work, we investigated the self-aggregation of the unmodified aromatic amino acid l-tryptophan (Trp) into unusual spherical microstructures. Using fluorescence spectroscopy and field emission scanning electron microscopy (FE-SEM), we detail the time-dependent transformation of monomeric tryptophan into spherical aggregates with distinct fluorescence characteristics (λ = 345 nm, λ = 430 nm) compared to the monomer.

Importance: Baseline cerebral microbleeds (CMBs) and APOE ε4 allele copy number are important risk factors for amyloid-related imaging abnormalities in patients with Alzheimer disease (AD) receiving therapies to lower amyloid-β plaque levels.
Objective: To provide prevalence estimates of any, no more than 4, or fewer than 2 CMBs in association with amyloid status, APOE ε4 copy number, and age.
Design, Setting, And Participants: This cross-sectional study used data included in the Amyloid Biomarker Study data pooling initiative (January 1, 2012, to the present [data collection is ongoing]).

From the Division of Urogynecology and Reconstructive Pelvic Surgery, Department of Gynecology and Obstetrics, Johns Hopkins University School of Medicine, Baltimore, MD.
Importance: Patients with urgency urinary incontinence are often recommended to avoid bladder irritants, but there is a lack of evidence for this.
Objective: The aim of the study was to compare consumption of purported bladder irritants between women with and without urgency urinary incontinence.
Study Design: We performed a case-control study of nonpregnant females aged ≥20 years using the National Health and Nutrition Examination Survey, 2007-2020.

Background: Boswellic acid (BA) is a bioactive compound derived from Boswellia trees. This study aims to investigate the anti-cancer properties of BA against KB oral squamous cancer cells and elucidate the underlying mechanisms.
Methods: Escalating doses of BA were administered to KB cells, and various analyses were conducted using bioinformatic tools such as GEO, GEO2R, and STITCH database.
