PURPOSE To assay for the presence of matrix metalloproteinases (MMPs) in human corneal epithelium affected by recurrent erosion compared with that in normal corneal epithelium. METHODS Corneal epithelial debridement samples were obtained from 13 patients with recurrent epithelial erosion. For control specimens, epithelia were obtained from healthy patients undergoing photorefractive keratecto...

BACKGROUND AND OBJECTIVES We assessed plaque erosion of culprit lesions in patients with acute coronary syndrome in real world practice. SUBJECTS AND METHODS Culprit lesion plaque rupture or plaque erosion was diagnosed with optical coherence tomography (OCT). Intravascular ultrasound (IVUS) was used to determine arterial remodeling. Positive remodeling was defined as a remodeling index (lesi...

An erosion hazard index methodology (EHIM) was developed for assessing stream erosion. The index of stream erosion is designed as a management tool. Assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. The assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. A ...

soil erosion is a major problem for developing countries with arid and semi-arid climate. these of erosion is possible than two ways of water and wind. in this paper, with using of two methods irifer and hierarchical models, the rate and intensity of of soil erosion is estimated shadegan catchment. for this purpose, by using various maps alike dem, rainfall, land use index, ndvi, geology estima...

anatomical changes of the exposed roots in cupressus sempervirens l. var horizontalis were used toestimate soil erosion in hassan abad valley, chaloos, iran. a total of 30 exposed roots, for five trees,were used to estimate erosion. cross-sections of 20 μm were papered and the first year of exposure byerosion was identified. we finally estimated the mean annual erosion. the statistical relation...

detachment, and sediment deposition are considered simultaneously. This approach has received experimenTwo modeling frameworks have been developed to describe and tal support (Proffitt et al., 1991; Proffitt et al., 1993; predict soil erosion and sediment deposition in recent years. The first Huang et al., 1999; Heilig et al., 2001), and lays the is based on the concept of transport capacity. D...

Background: Bone erosion is a common manifestation of sinus fungus ball (SFB) on CT imaging, however, the relationship between CT imaging and clinical features of SFB with bone erosion were not clear. Purpose: To evaluate the CT imaging and clinical features of sinus fungus ball with bone erosion and to explore the possible factors underlying its formation. Material and methods: The clinical da...

The rivers from the Himalaya supply large quantities of particulate and dissolved materials to the oceans. Among the various rivers, the Brahmaputra ranks highest in contributing to the sediment budget of the Bay of Bengal. The erosion rates among the sub-basins of the Brahmaputra vary over 1–2 orders of magnitude, the highest being in the Eastern Syntaxis basin which is eroding at an enormousl...

AIM To investigate any association between dental erosion and its potential dietary risk factors in a group of schoolchildren in Benghazi, Libya. STUDY DESIGN A cross-sectional observational study. METHODS A random sample of 12-year-old schoolchildren in 36 randomly selected schools completed a questionnaire to provide dietary data and underwent dental examination. Dental erosion was assess...

This in situ/ex vivo study assessed the effect of different concentrations of fluoride in dentifrices on dentin subjected to erosion or to erosion plus abrasion. Ten volunteers took part in this crossover and double-blind study performed in 3 phases (7 days). They wore acrylic palatal appliances containing 4 bovine dentin blocks divided in two rows: erosion and erosion plus abrasion. The blocks...
