This article reviews the current techniques employed to assess endothelial dysfunction in different categories of smokers. Simple but effective methods to assess regional and local properties of large arteries for epidemiologic studies are firstly discussed. After, more complex but accurate image-based methods are described. In particular, the role of high resolution magnetic resonance to quantify, in a single examination, vascular function at different sites of peripheral and central arteries is summarized. Finally, the role of positron emission tomography and magnetic resonance flow mapping are described to assess myocardial microcirculation at rest and under external stressors.

Background noise interferes with the accurate detection of early tumor biomarkers. This study introduces a method that effectively reduces background noise to enhance detection accuracy by combining a color-coded signaling approach with the unique fluorescent properties and room-temperature tunable quantum spin characteristics of fluorescent diamonds (FNDs) with nitrogen-vacancy centers. In this approach, a red signal indicates the presence of the target analyte within the spectral region, a green signal indicates its absence, and a yellow signal indicates the need for further analysis using FNDs' quantum spin properties for optical detection magnetic resonance (ODMR) to distinguish the FND signal from background noise.

Nanographenes and polycyclic aromatic hydrocarbons, both finite forms of graphene, are promising organic semiconducting materials because their optoelectronic and magnetic properties can be modulated through precise control of their molecular peripheries. Several atomically precise edge structures have been prepared by bottom-up synthesis; however, no systematic elucidation of these edge topologies at the molecular level has been reported. Herein, we describe rationally designed modular syntheses of isomeric dibenzoixenes with diverse molecular peripheries, including cove, zigzag, bay, fjord, and gulf structured.

Background: Goldenhar syndrome is a clinically heterogeneous disorder defined by a rare combination of congenital anomalies-an eye abnormality, in addition to two of the following three: ear anomalies, mandibular malformations, and vertebral defects. Notably, children with Goldenhar syndrome present with a high incidence of cervical spine malformations.
Clinical Case: In this report, we present an unusual case of a 15-year-old child with Goldenhar syndrome, who additionally presents with some clinical features of VACTERL syndrome.

We present a high-resolution single crystal x-ray diffraction study of kagome superconductor CsV_{3}Sb_{5}, exploring its response to variations in pressure and temperature. We discover that at low temperatures, the structural modulations of the electronic superlattice, commonly associated with charge-density-wave order, undergo a transformation around p∼0.7 GPa from the familiar 2×2 pattern to a long-range-ordered modulation at wave vector q=(0,3/8,1/2).

We present a novel resonance mode in capacitive radio frequency (rf) discharges in the presence of an oblique magnetic field at low pressures. We observe the self-excitation of high-frequency harmonics of the current in magnetized capacitive rf discharges through the magnetized plasma series resonance (MPSR) induced by applying a low-frequency power. Utilizing an equivalent circuit model, we reveal that these harmonics arise from the hybrid combination of the magnetic gyration of electrons and the PSR.
