A novel testing system for hydromechanical investigation of rock materials in neutron and X-ray imaging instruments

This article introduces a novel testing system for investigating rock hydromechanical behavior with neutron and X-ray imaging techniques. The system comprises four subsystems: an axial compression system, a confining pressure system, a fluid flow system, and a triaxial cell. In order to enable imaging with both modalities to track fluid flow and deformation in situ and 3D, the cell was designed to

Computational exploration of FOXM1 inhibitors for glioblastoma : an integrated virtual screening and molecular dynamics simulation study

In this study, a comprehensive investigation of a set of phytochemicals to identify potential inhibitors for the Forkhead box protein M1 (FOXM1) was conducted. FOXM1 is overexpressed in glioblastoma (GBM) cells and plays a crucial role in cell cycle progression, proliferation, and invasion. FOXM1 inhibitors have shown promising results in preclinical studies, and ongoing clinical trials are assess

Dual-binary phase gratings for x-ray interferometry

X-ray phase-contrast imaging by grating interferometry has in the past decades been established both at synchrotron radiation sources and at conventional x-ray tubes. Due to the sensitivity to x-ray phase shifting, contrast in soft tissue has been improved significantly and the possibilities to do virtual histology of tissue biopsies are being pioneered. Constraints in the design of a grating inte

MERTK in the rat trigeminal system : a potential novel target for cluster headache?

The trigeminal system is key to the pathophysiology of migraine and cluster headache, two primary headache disorders that share many features. Recently, MER proto-oncogene tyrosine kinase (MERTK), a cell surface receptor, was strongly associated with cluster headache through genetic studies. Further, the MERTK ligand galectin-3 has been found to be elevated in serum of migraine patients. In this s

Technocultural worldings: dialectical dynamics in contemporary media landscapes

In this piece, which frames the special issue “Technocultural worldings,” we build on previous editions of commentary and criticism in this journal. We propose a theoretically anchored way to systematically approach the dynamic, multidimensional, and heterogeneous technocultural communities that have created their own worldings and are engaged in complex dialectical dynamics within the contemporar

Video analysis of bicyclist and pedestrian movement on shared-use paths under daylight and electric lighting conditions : Method exploration

This study introduces a progressive methodology for examining the travel behaviour of bicyclists and pedestrians under both daylight and electric lighting conditions. By analysing data from naturalistic/undisturbed settings, we aimed to assess the representativeness of participant behaviour in an invited context compared to that of typical road users. This paper expands upon the methodological exp

A general method for the immobilization of cells with preserved viability

Microbial, algal, plant and animal cells have been immobilized, with preserved viability, by entrapment in various matrices according to a new bead polymerization technique. The cell polymer/monomer mixture is kept suspended in a hydrophobic phase such as soy, paraffin, or silicon oil, tri-n-butylphosphate, or dibutyphtalate, which is compatible with the cells. The various monomers or polymers tes

In-situ light extinction nano-oxide volume fraction measurements during single iron particle combustion

In-situ measurements of the volume fraction of nanoparticles generated during the combustion of single iron particles were conducted using a high-speed light extinction method. The process of nanoparticles generation from iron particles burning under conditions of 21% oxygen concentration and ambient temperatures of 1400 K and 1850 K can be divided into three stages: acceleration of productivity,

Flame front visualization in turbulent premixed ethylene/air flames by laser-induced photofragmentation fluorescence

The elucidation of premixed ethylene/air combustion mechanisms holds theoretical significance for optimizing engines such as pulse detonation engines and rotating detonation engines. The flame front structure constitutes a vital factor of premixed ethylene/air combustion mechanisms, while the prevailing planar laser-induced fluorescence techniques currently in use fall short of directly visualizin

On the wear mechanisms of uncoated and coated carbide tools in milling titanium alloys

Titanium alloys are known for being difficult to machine. Within the groups of Ti alloys, the machinability is reduced when going from the α-alloys, to α + β, and finally to near-β or β-alloys. Uncoated cemented carbide is traditionally used for machining these alloys and finding a suitable coating to improve the performance is a challenge due to the high strength of Ti alloys and the high chemica

Unraveling UVB effects : Catalase activity and molecular alterations in the stratum corneum

Aim: Ultraviolet B (UVB) radiation can compromise the functionality of the skin barrier through various mechanisms. We hypothesize that UVB induce photochemical alterations in the components of the outermost layer of the skin, known as the stratum corneum (SC), and modulate its antioxidative defense mechanisms. Catalase is a well-known antioxidative enzyme found in the SC where it acts to scavenge

Metabolic and angiogenic biomarkers in breast cancer: potential clinical implications of host–tumor interactions

Background: Both caveolin-1 (CAV1) and insulin-like growth factor bindings protein 7 (IGFBP7) have been linked to angiogenesis, insulin-like growth factor (IGF) receptor 1 (IGF-1R) signaling, and the tumor microenvironment. However, CAV1 and IGFBP7 have not yet been adequately characterized and investigated as potential prognostic or treatment-predictive biomarkers at the genomic, transcriptomic,

Translation and ligusistic Validation of the Multidimensional Dyspnea Profile into Hindi in a Palliative Care setting

Objectives:The Multidimensional Dyspnea Profile (MDP) comprehensively addresses dyspnea, incorporating both perceptual and affective components, and has proven effective in assessing breathlessness among patients with chronic lung conditions. Despite its validation in High-Income Countries, its applicability in Low/Middle-Income countries remains uncertain. Additionally, the MDP has not been trans

Gluten-free diet for pediatric patients with coeliac disease : A position paper from the ESPGHAN gastroenterology committee, special interest group in coeliac disease

Background and Objective: Coeliac disease is a chronic, immune-mediated disorder for which the only treatment consists of lifelong strict adherence to gluten-free diet (GFD). However, there is a lack of evidence-based guidelines on the GFD dietary management of coeliac disease. This position paper, led by the Special Interest Group in coeliac disease of the European Society of Pediatric, Gastroent

Robust Localization of Close-Range Radar Reflections

In order to allow for a computationally efficient estimation of radar reflections, one commonly assumes the reflecting target to be in the far-field of the sensing array, such that the impinging wavefront is modeled as a linear phase-shift along the array. This works well in most radar scenarios, but causes significant performance degradation for close-range radar systems, wherein the curvature of

Observation of Structural Changes during Oxidation of Black and Brown Soot Using Raman Spectroscopy

In this study, Raman spectroscopy has been used to evaluate the evolution of the structural modification of soot during oxidation processes at various preset temperatures up to 700 °C. Two types of well-characterized mini-CAST soot, representing black soot and brown soot, were examined. The major difference between the signals from the two types of soot was the higher photoluminescence (PL) signal
