: The increased SNR available at 7T combined with fast readout trajectories enables accelerated spectroscopic imaging acquisitions for clinical applications. In this report, we evaluate the performance of a Hadamard slice encoding strategy with a 2D rosette trajectory for multi-slice fast spectroscopic imaging at 7T. : Moderate-TE (~40 ms) spin echo and J-refocused polarization transfer sequences were acquired with simultaneous Hadamard multi-slice excitations and rosette in-plane encoding.

Keratinocytes are the primary component of the epidermis, so maintaining the precise balance between proliferation and differentiation is essential for conserving epidermal structure and function. Rosae multiflorae fructus extract (RMFE) has wide application in the cosmetic industry, but the molecular mechanisms underlying beneficial effects on keratinocytes are still not fully understood. In this study, we found that RMFE promoted epidermal differentiation and enhanced the barrier function of normal human epidermal keratinocytes (NHEKs) and three-dimensional epidermis model in culture.

Identifying facile strategies for hierarchically structuring crystalline porous materials is critical for realizing diffusion length scales suitable for broad applications. Here, we elucidate synthesis-structure-function relations governing how room temperature catalytic conditions can be exploited to tune covalent organic framework (COF) growth and thereby access unique hierarchical morphologies without the need to introduce secondary templates or structure directing molecules. Specifically, we demonstrate how scandium triflate, an efficient catalyst involved in the synthesis of imine-based COFs, can be exploited as an effective growth modifier capable of selectively titrating terminal amines on 2D COF layers to facilitate anisotropic crystal growth.

Adenomatoid odontogenic tumors (AOT), first described by Steensland in 1905, are benign, slowly enlarging, nonaggressive, odontogenic epithelial neoplasms comprising 3%-7% of all odontogenic tumors. They tend to originate from the dental lamina remnants or the reduced enamel epithelium. Mutation at codon 12 of KRAS oncogene (Kirsten rat sarcoma viral oncogene homolog) plays a pivotal role in the pathogenesis.
