The Role of Trace Elements in the Formation of Feline Corneal Sequestra. [PDF]

Vet Ophthalmol
ABSTRACT Objective To characterize the trace element composition of feline corneal sequestra (FCS) and provide insights into their pathophysiology. Methods FCS samples were collected from 11 eyes of 9 cats following keratectomy and compared with corneal samples from four clinically normal control cats euthanized for reasons unrelated to the study ...

Polymeric Membranes Doped with Halloysite Nanotubes Imaged using Proton Microbeam Microscopy [PDF]

Nanomaterials, 2023
Polymeric membranes are useful tools for water filtration processes, with their performance strongly dependent on the presence of hydrophilic dopants. In this study, polyaniline (PANI)-capped aluminosilicate (halloysite) nanotubes (HNTs) are dispersed ...

Quantification of ¹⁰B and ¹¹B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT). [PDF]

Med Res Rev
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Fluoride Retention in Root Dentin following Surface Coating Material Application [PDF]

Journal of Functional Biomaterials, 2023
This study aimed to use an in-air micro-particle-induced X-ray/gamma emission (in-air µPIXE/PIGE) system to evaluate tooth-bound fluoride (T-F) in dentin following the application of fluoride-containing tooth-coating materials.

Metal Ions in Longgu (Fossilized Bone) as a Natural Synergistic Network for Multi-Target Therapy in Psychiatric Disorders. [PDF]

Chem Biodivers
Longgu (fossilized bone) delivers a natural synergistic network of metal ions, Ca2+, Mg2+, Zn2+, Fe, Cu, and Mn2+ that collectively targets the interconnected pathologies of anxiety, depression, and insomnia. This multi‐ion system operates through coordinated mechanisms including ionostatic balance, cross‐pathway synergy, and systemic integration ...

Elemental analysis of lung tissue particles and intracellular iron content of alveolar macrophages in pulmonary alveolar proteinosis

Respiratory Research, 2011
Background Pulmonary alveolar proteinosis (PAP) is a rare disease occurred by idiopathic (autoimmune) or secondary to particle inhalation. The in-air microparticle induced X-ray emission (in-air micro-PIXE) system performs elemental analysis of materials

PIXE and Its Applications to Elemental Analysis

Quantum Beam Science, 2019
When charged particles collide with atoms, atomic inner shell electrons become ionized, producing characteristic X-rays. This phenomenon is called particle-induced X-ray emission (PIXE).
