Mulberry Particles Formed by Red Blood Cells in Human Weddelite Stones
Journal of Urology, 1983In a series of electron microscopic studies of human urinary stones, mulberry shaped particles were observed in 5 out of 51 calcium oxalate dihydrate (COD) containing stones. The mulberries were crenation products of red blood cells which adhered to the surface of bipyramid COD crystals, followed by impregnation of the COD.

International Biodeterioration & Biodegradation, 2014
The inhabitation of microorganisms and their subsequent interaction with mineral matrix of the stone substrate under varied environmental conditions encourages deterioration of stones leading to the loss of strength, durability and aesthetic. This study highlighted the synthesis of nanosilver particles (AgNPs) using the biogenic volatiles of the ...

Journal of Cereal Science, 2020
Abstract The poor technological performance of weak wheat flours means that they are usually considered difficult to be transformed into satisfactory bread. During milling, there are several settings that can affect flour characteristics. In this study, we tested two operative parameters that have the potential to affect flour quality – stone ...

The expectation of free and fixed particles in urinary stone disease.
Investigative urology, 1978There is a paucity of literature concerning the origin of urinary stone disease. This report uses information currently available to examine the likelihood of urinary stone disease starting from free or fixed crystalluric particles. We conclude that stone disease in the renal tubules and renal pelvis cannot begin on unattached (free) particles. However,

Studies on the effect of particle size on some properties of dental stone
Journal of Materials Science, 1979Most indirect dental restorations of gold or porcelain are constructed on stone working models or dies. If these models or dies are damaged during the construction of these restorations in the laboratory, then the clinical success of the restoration will be jeopardized.

Fine particle removal from natural stone processing effluent by flocculation
Environmental Progress & Sustainable Energy, 2012In this study, the sedimentation behaviors of five different natural stones (i.e., marble and travertine suspansions) were examined by applying classical sedimentation tests. The suspensions were first characterized using electrokinetic and physical analysis techniques and then subjected to gravity and flocculation aid sedimentation tests to find the ...

RAT LUNG INFLAMMATORY RESPONSES AFTER IN VIVO AND IN VITRO EXPOSURE TO VARIOUS STONE PARTICLES
Inhalation Toxicology, 2001Rat lung alveolar macrophages and type 2 cells were exposed for 20 h in vitro to various stone particles with differing contents of metals and minerals (a type of mylonite, gabbro, feldspar, and quartz). The capability to induce the release of the inflammatory cytokines interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-alpha), and macrophage ...

Detection and isolation of nanobacteria‐like particles from urinary stones: Long‐withheld data
International Journal of Urology, 2011Objectives: To report our experimental results on detection and isolation of nanobacteria‐like particles (NLP) from urinary stone samples.Methods: From March 2001 to August 2003, 47 urinary stone samples from Japanese patients and 18 from Paraguayan patients were collected and used for compositional analysis, direct survey of NLP by scanning electron

The Role of Particle Size in Engineered Stone Induced Lung Cell Responses
American Journal of Respiratory and Critical Care MedicineAbstract Rationale: The surge in silicosis cases among engineered stone (ES), also known as artificial stone, workers is a global health disaster. This has been linked to the high levels of respirable crystalline silica (RCS) that workers processing ES may be exposed to.
