3D Imaging Resolves Human Pancreatic Duct-β-Cell Clusters During Cystic Change.

Pancreatic cystic changes in adults are increasingly identified through advanced cross-sectional imaging. However, the impact of initial/intra-lobular epithelial remodeling on the local β-cell population remains unclear. In this study, we examined 10 human cadaveric donor pancreases (tail and body regions) via integration of stereomicroscopy, clinical H&E histology, and 3D immunohistochemistry, identifying 36 microcysts (size: 1.

Biomarkers.

Background: Vascular cognitive impairment (VCI), including vascular cognitive impairment-no dementia (VCIND) and vascular dementia, is a cognitive impairment syndrome caused by cerebrovascular disease and its risk factors. Among people over 60 years old, the prevalence of VCIND is about 15-20%. VCIND, as the early stage of VCI, has become a focus of current research due to the fact that its patients are at greater risk of developing dementia and can benefit greatly from early intervention.

Co-evolutionary dynamics of microbial communities and flavor profiles during natural fermentation of Cabernet Sauvignon and Merlot: A comparative study within a single vineyard.

Indigenous microorganisms play a crucial role in determining the quality of naturally fermented wines. However, the impact of grape cultivar specificity on microbial composition is often overshadowed by the geographical location of the vineyard, leading to underestimation of its role in natural wine fermentation. Therefore, this study focuses on different grape cultivars within a single vineyard.

Highly hydrophobic calixarene polymers for efficient enrichment of polar nitrobenzene compounds.

Macrocyclic polymer materials exhibit excellent selectivity and adsorption performance in pollutant adsorption due to unique host-guest recognition. Herein, three kinds of calixarene polymers (C4P, C6P and C8P) were synthesized through Sonogashira reaction, and were characterized through H NMR, FT-IR, SEM, and TEM. The water contact angle experiments revealed that three kinds of calixarene polymers were highly hydrophobic, and they all exhibited high enrichment efficiency for weak polar chloro-substituted benzene compounds (chlorobenzene, o-chlorotoluene, p-dichlorobenzene and o-dichlorobenzene) and BTEX (benzene, toluene, ethylbenzene and xylenes).
