Preharvest Treatment with Melatonin Improves Antioxidant and Phenylpropanoid Pathways During Postharvest Storage.

is known for its popularity and robust nutritional value. While fresh fruit is a perishable commodity, it has a short post-harvest life and is susceptible to fungal decay after harvest. Melatonin has been reported to delay the aging and quality decline of various fruits and vegetables after harvest.

Maternal Exposure to Polystyrene Nanoplastics Disrupts Spermatogenesis in Mouse Offspring by Inducing Overexpression in Undifferentiated Spermatogonia.

Undifferentiated spermatogonia (Undiff-SPG) plays a critical role in maintaining continual spermatogenesis. However, the toxic effects and molecular mechanisms of maternal exposure to nanoplastics on offspring Undiff-SPG remain elusive. Here, we utilized a multiomics combined cytomorphological approach to explore the reproductive toxicity and mechanisms of polystyrene nanoplastics (PS-NPs) on offspring Undiff-SPG in mice after maternal exposure.

Charge Transfer Effect in Layered Cathodes Through MEMS-Based In Situ TEM Studies.

The irreversible lattice oxygen release is the primary issue in layered oxide cathodes which is generally attributed to a consecutive phase transition with less lattice oxygen content. Herein, an anomalous metal segregation pathway is observed in oxygen vacancy defective layered cathodes, which happens far before the onset of phase transitions. The correlation of electron energy loss spectroscopy indicates that an early charge transfer from oxygen 2p to Mn 3d orbital is responsible.

Supercarbon assembly inspired two-dimensional hourglass fermion.

By using a tight-binding model, first-principles calculations, and ab initio molecular dynamics simulations, we theoretically demonstrate that the C76-Td-assembled two-dimensional (2D) honeycomb lattice is stable at room temperature and is resistant to mechanical deformation. We disclose that each C76-Td mimics a single carbon atom (geometrically and electronically); hence, it plays the role of one supercarbon. This inspires that the 2D material exhibits an exotic hourglass-like fermion at the Fermi level.

Novel MRI-based Hyper-Fused Radiomics for Predicting Pathologic Complete Response to Neoadjuvant Therapy in Breast Cancer.

Rationale And Objectives: To propose a novel MRI-based hyper-fused radiomic approach to predict pathologic complete response (pCR) to neoadjuvant therapy (NAT) in breast cancer (BC).

Materials And Methods: Pretreatment dynamic contrast-enhanced (DCE) MRI and ultra-multi-b-value (UMB) diffusion-weighted imaging (DWI) data were acquired in BC patients who received NAT followed by surgery at two centers. Hyper-fused radiomic features (RFs) and conventional RFs were extracted from DCE-MRI or UMB-DWI.
