Catalyst-derived hierarchy in 2D imine-based covalent organic frameworks.

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.

Prioritizing Oral Health: Oral Health IS Health!

How did we let the mouth get separated from the rest of the body? And more importantly, how do we put oral health back into overall health? This issue of the NCMJ highlights recent efforts to develop strategies to create an accessible, sustainable, and equitable care delivery system in North Carolina.

Long-term Radiation Signal Persistence in Urine and Blood: A Two-year Analysis in Non-human Primates Exposed to a 4 Gy Total-Body Gamma-Radiation Dose.

National security concerns regarding radiological incidents, accidental or intentional in nature, have increased substantially over the past few years. A primary area of intense planning is the assessment of exposed individuals and timely medical management. However, exposed individuals who receive survivable radiation doses may develop delayed effects of acute radiation exposure many months or years later.

Vitamin D Significantly Inhibits Carcinogenesis in the Mogp-TAg Mouse Model of Fallopian Tube Ovarian Cancer.

Epidemiological and observational studies suggest that vitamin D has potential for the chemoprevention of ovarian cancer. The anticancer effect of vitamin D in the fallopian tube epithelium (FTE), which is now thought to harbor the precursor cells for high grade ovarian cancer, is not known. The purpose of this study was to investigate whether vitamin D can inhibit carcinogenesis in the mogp-TAg fallopian tube (FT) ovarian cancer mouse model and examine underlying mechanisms.
