Pressure Sensitivity of UiO-66 Framework with Encapsulated Spin Probe: A Molecular Dynamics Study

open access: yesMolecules
Probes sensitive to mechanical stress are in high demand for analyzing pressure distributions in materials. Metal–organic frameworks (MOFs) are especially promising for designing pressure sensors due to their structural tunability.

Exchange coupling transformations in Cu (II) heterospin complexes of “breathing crystals” under structural phase transitions

open access: yesAIP Advances, 2015
Family of “breathing crystals” is the polymer-chain complexes of Cu(hfac)2 with nitroxides. The polymer chains consist of one-, two- or three-spin clusters.

Hadron Tomography [PDF]

open access: yesAIP Conference Proceedings, 2006
Generalized parton distributions can be used to obtain information about the dependence of parton distributions on the impact parameter. Potential consequences for T -odd single-spin asymmetries are discussed.

The possibilities of the non-contrast MRI perfusion in the quantitative assessment of changes in cerebral blood flow

open access: yesСибирский научный медицинский журнал
Arterial spin labeling (ASL) allows the assessment of tissue perfusion and has advantages such as non-invasiveness and the ability to repeat examinations multiple times. This enables dynamic monitoring without contrast administration.

Development of an automated method for in-house production of sodium 18F-fluoride for injection: process validation as a step toward routine clinical application

open access: yesEJNMMI Radiopharmacy and Chemistry
Background Sodium 18F-fluoride for injection can be easily cyclotron-produced and purified, as a simple inorganic salt, by adsorption/desorption onto an anion-exchange cartridge and then dispensed for clinical use.

Pressure-Induced Stromal Keratopathy after Surface Ablation Surgery

open access: yesCase Reports in Ophthalmology
Introduction: The purpose of this clinical report was to describe an unprecedented case of bilateral pressure-induced stromal keratopathy (PISK) following corneal photorefractive keratectomy, associated with presumed herpetic keratitis, and to present ...

Comparison of diffusion MRI methods in the study of structural reorganization of the brain in the early post-stroke period

open access: yesСибирский научный медицинский журнал
Current research in the field of neuroimaging is focused on the possibilities of using data from various diffusion MR models: diffusion tensor visualization (DTI), diffusion-curtosis visualization (DKI), diffusion-spectral visualization (DSI ...

Optical Coherence Tomography [PDF]

open access: yesThe Scientific World JOURNAL, 2007
Optical coherence tomography (OCT) is an optical imaging modality that performs high-resolution, cross-sectional, subsurface tomographic imaging of the microstructure of tissues. The physical principle of OCT is similar to that of B-mode ultrasound imaging, except that it uses infrared light waves rather than acoustic waves.

Occult Spinal Dysraphism in the Presence of Rare Cutaneous Stigma in a Neonate: Importance of Ultrasound and Magnetic Resonance Imaging

open access: yesCase Reports in Medicine, 2013
Occult spinal dysraphism is defined as a group of dystrophic conditions below an intact cover of dermis and epidermis. Ultrasonography using linear transducers is a fast, inexpensive, and effective method that makes it possible to view the content of the
