Purpose The purpose of this study was to evaluate the efficacy of the modified plaque score (MPS) for assessing the oral hygiene status of periodontitis patients. Methods A total of 116 patients were included in this study. After evaluation of the Löe and Silness gingival index (GI), Silness and Löe plaque index (PlI), O'Leary plaque control record (PCR), and MPS, patients were randomly assig...

Changes in microparticles (MP) from red blood cell (RBC) concentrates in the context of irradiation have not been investigated. The aim of this study was to evaluate how irradiation affects the number of MPs within transfusion components. Twenty RBC concentrates, within 14 days after donation, were exposed to gamma rays (dose rate: 25 cGy) from a cesium-137 irradiator. Flow cytometry was used t...

OBJECTIVE To examine mortality in members of the two UK Houses of Parliament compared with the general population, 1945-2011. DESIGN Retrospective cohort analysis of death rates and predictors of mortality in Members of Parliament (MPs) and members of the House of Lords (Lords). SETTING UK. PARTICIPANTS 4950 MPs and Lords first joining the UK parliament in 1945-2011. MAIN OUTCOME MEASUR...

Membrane-shed submicron microparticles (MPs) are released after cell activation or apoptosis. High levels of MPs circulate in the blood of patients with atherothrombotic diseases, where they could serve as a useful biomarker of vascular injury and a potential predictor of cardiovascular mortality and major adverse cardiovascular events. Atherosclerotic lesions also accumulate large numbers of M...

Mucopolysaccharidoses (MPS) are rare lysosomal disorders caused by the deficiency of specific lysosomal enzymes responsible for glycosaminoglycan (GAG) degradation. Enzyme Replacement Therapy (ERT) has been shown to reduce accumulation and urinary excretion of GAG, and to improve some of the patients' clinical signs. We studied biochemical and molecular characteristics of nine MPS patients (two...

Since the publication of our recently developed mode-pursing sampling (MPS) method, questions have been asked on its performance as compared with traditional global optimization methods such as genetic algorithm (GA), and when to use MPS as opposed to GA. This work aims to provide an answer to these questions. Similarities and distinctions between MPS and GA are presented. Then MPS and GA are c...

MR imaging of the brain was performed in eight patients with mucopolysaccharidosis (MPS). Two had MPS I S, one had MPS IIA, two had MPS IIB, two had MPS IIIB, and one had MPS VI. In the patients with MPS IIA and MPS VI, T1 and T2 were prolonged in various areas of the cerebral white matter. These findings seemed to correspond with the development of pathologic changes in MPS, such as perivascul...

Ocular changes in some types of the mucopolysaccharidoses (MPS) include corneal clouding, glaucoma, pigmentary retinopathy, optic disc edema, and optic atrophy. Pigmentary retinopathy has been reported in MPS I (Hurler disease), MPS I-S (Scheie syndrome), MPS I-H/S (Hurler/Scheie), MPS II (Hunter disease), MPS III (Sanfilippo syndrome), and MPS IV A (Morquio A syndrome). Clinical signs of retin...

Sanfilippo syndrome, or mucopolysaccharidosis (MPS) type III, refers to one of five autosomal recessive, neurodegenerative lysosomal storage disorders (MPS IIIA to MPS IIIE) whose symptoms are caused by the deficiency of enzymes involved exclusively in heparan sulfate degradation. The primary characteristic of MPS III is the degeneration of the central nervous system, resulting in mental retard...

BACKGROUND Microparticles (MPs) are circulating membrane particles of less than a micrometer in diameter shed from endothelial and blood cells. Recent literature suggests that MPs are not just functionally inert cell debris but may possess biological functions and mediate the communication between vascular cells. As a significant proportion of MPs originate from platelets and endothelial cells,...
