This study investigated the impacts of growth seasons and maturity stages on the processing properties of starch isolated from 'Dwarf Cavendish' banana. The analysis revealed that seasonal variations and maturity stages had significant impacts on the characteristics of the starch. Summer banana starch (SBS) demonstrated a more ordered structure, enhanced thermal stability, higher viscosity, and increased content of resistant starch (RS) compared to winter banana starch (WBS). Moreover, several parameters of starch significantly increased during the maturity stage progressed from 60 to 90 %. Specifically, the relative crystallinity rose from 27.50 to 32.13 % in SBS and from 17.05 to 22.19 % in WBS. The peak viscosity increased from 5064 to 5354 cP in SBS and from 4992 to 5086 cP in WBS. Additionally, RS content increased from 85.20 to 90.71 % in SBS and from 80.55 to 86.99 % in WBS. Principal component analysis showed that SBS at 90 % maturity exhibited high thermal stability, viscosity, and RS content, positioning it as a multifunctional source suitable for starch-derived food products. This research presented an understanding of the variations in properties of banana starches during different growth seasons and maturity stages, providing valuable insights for their application in food products.

Traditionally, oligodendrocyte precursor cells (OPCs) were primarily regarded for their differentiation potential to mature oligodendrocytes that ensheath central nervous system (CNS) axons through myelin formation. Recent breakthroughs in single-cell sequencing and in vivo imaging technologies have revolutionized our understanding, revealing that OPCs engage in extensive dynamic interactions with diverse CNS cell populations during neurodevelopment, tissue homeostasis maintenance, and pathological microenvironment remodeling. Notably, while OPCs exhibit relatively conserved phenotypic signatures, their functional plasticity within heterogeneous microenvironments demonstrates significant spatial specificity and disease-context dependence.

Dynamic control of ciliary membrane protein content is crucial for the organelle's homeostasis and signaling function and involves removal of ciliary components by intraflagellar transport (IFT) and BBSome-mediated export, endocytic retrieval, and/or extracellular vesicle (EV) shedding. We report that the kinesin-3 motor KIF13B regulates ciliary protein composition and EV shedding in cultured kidney epithelial cells, with effects that vary over time. In early stages of ciliation, Kif13b cells aberrantly accumulate polycystin-2 (PC2) within cilia and release large EVs enriched with CCDC198 and the centriole distal appendage protein CCDC92, which also localizes to the ciliary tip.

Mogrosides are the main non-caloric sweeteners in Siraitia grosvenorii, with sweetness determined by specific chemical structures. However, the diversity of triterpenoid skeletons and glucosylation patterns suggests that the variety of mogrosides remains insufficiently characterized. Here, high-resolution mass spectrometry (HRMS) coupled with Global Natural Products Social Molecular Networking (GNPS) was used to systematically profile mogrosides.

Auricular reconstruction is essential for restoring facial symmetry and achieving a well-contoured, natural-appearing ear. Traditional methods using autologous costal cartilage often delay reconstruction until around age 10, when sufficient rib cartilage is available, which can pose physical and psychological challenges for pediatric patients. Porous high-density polyethylene (PHDPE) implants offer significant advantages, including the ability to perform reconstruction earlier, reduced morbidity, improved ear definition, and the possibility of a single-stage outpatient procedure.

Sequestration of Plasmodium falciparum-infected erythrocytes (IE) in the microvasculature is a major virulence determinant. While the sequestration of mature stage parasites (trophozoite and schizonts) to vascular endothelium is well established, the conditions that promote ring-stage IE sequestration is less understood. Here, we observed in ring-stage parasites that febrile exposure increased transcript levels of several exported parasite genes involved in the trafficking of the P.
