Surface Chemistry of a Halogenated Borazine: From Supramolecular Assemblies to a Random Covalent BN-Substituted Carbon Network.

The on-surface synthesis strategy has emerged as a promising route for fabricating well-defined two-dimensional (2D) BN-substituted carbon nanomaterials with tunable electronic properties. This approach relies on specially designed precursors and requires a thorough understanding of the on-surface reaction pathways. It promises precise structural control at the atomic scale, thus complementing chemical vapor deposition (CVD).

Assessing Microplastics and Nanoparticles in the Surface Seawater of Venice Lagoon-Part I: Methodology of Research.

Microplastics (MPs) and nanoplastics (NPs) both represent significant concerns in environmental sciences. This paper aims to develop a convenient and efficient methodology for the detection and measurement of MPs and nanoparticles from surface seawater and to apply it to the water samples collected from the UNESCO site of Venice and its lagoon, more precisely in the Venice-Lido Port Inlet, Grand Canal under Rialto Bridge, and Saint Marc basin. In this study, MPs were analyzed through optical microscopy for their relative abundance and characterized based on their color, shape, and size classes, while the concentration and the mean of nanoparticles were estimated via the Nanoparticle Tracking Analysis technique.

Association between epithelial-mesenchymal transition markers, proliferative index, and oral epithelial dysplasia: an immunohistochemical study.

Objective: This study aimed to correlate the immunoexpression of epithelial-mesenchymal transition markers, vimentin and E-cadherin (E-CAD), and putative markers, podoplanin (PDPN) and osteopontin (OTPN), with the expression of interleukin (IL-6), P53, and Ki-67, and with clinical and histologic parameters of oral epithelial dysplasia (ED).

Study Design: Immunohistochemical reactions were performed in 61 cases of leukoplakia with ED, graded as low-risk (LRED = 38) and high-risk (HRED = 23) for malignant transformation. Odds ratios (OR) and 95% CI were calculated using logistic regression analysis.

Preclinical in vivo animal models of intervertebral disc degeneration. Part 1: A systematic review.

Intervertebral disc degeneration (IVDD), a widely recognized cause of lower back pain, is the leading cause of disability worldwide. A myriad of preclinical in vivo animal models of IVDD have been described in the literature. There is a need for critical evaluation of these models to better inform researchers and clinicians to optimize study design and ultimately, enhance experimental outcomes.
