We present new observations of pyroclastic deposits on the surface of Mercury from data acquired during the orbital phase of the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) mission. The global analysis of pyroclastic deposits brings the total number of such identified features from 40 to 51. Some 90% of pyroclastic deposits are found within impact craters. The loca...

Gou A large number of candidate open-basin lakes (low-lying regions with both inlet valleys and an outlet valley) have been identified and mapped on Mars and are fed by valley network systems that were active near the Noachia...
Aggregation is a common process occurring in many diverse particulate gas mixtures (e.g. those derived from explosive volcanic eruptions, meteorite impact events, and fluid bed processing). It results from the collision and sticking of particles suspended in turbulent gas/air. To date, there is no generalized model of the underlying physical processes. Here, we investigate aggregates from 18 na...
Immunocytochemical methods were used to study the nature of the amyloid deposits in the Finnish type-familial amyloid polyneuropathy (FAP) type IV, which is characterized by cranial neuropathy and corneal lattice dystrophy. Commercial antisera to human plasma transthyretin (prealbumin) did not stain the amyloid deposits, but in every case a positive staining was obtained with antibodies raised ...
Deposition of β-amyloid (Aβ), a 'signature' pathological lesion of Alzheimer's disease (AD), is also characteristic of Down's syndrome (DS), and has been observed in dementia with Lewy bodies (DLB) and corticobasal degeneration (CBD). To determine whether the growth of Aβ deposits was similar in these disorders, the size frequency distributions of the diffuse ('pre-amyloid'), primitive ('neurit...
OBJECTIVE To evaluate whether otosclerosis is an underlying mechanism for the production of cupular deposits and to study the association between cupular deposits and dysequilibrium in otosclerosis. DESIGN Retrospective human temporal bone (TB) study. The incidence of cupular deposits in these 70 TBs was analyzed. Correlations between cupular deposits and vestibular symptoms, endosteal involv...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
Mucin deposit is a feature that is not commonly mentioned in textbooks when talking about rosacea. Nevertheless, it is one of the prominent findings of a severe variant of the phymatous type of rosacea known as the fibrous type. We retrospectively investigated 20 cases of early stages of rosacea and examined the mucin deposit in them, with histochemical stains (Alcian Blue and Periodic Acid-Sch...
Amyloid deposits are proteinaceous extra-cellular aggregates associated with a diverse range of disease states. These deposits are composed predominantly of amyloid fibrils, the unbranched, beta-sheet rich structures that result from the misfolding and subsequent aggregation of many proteins. In addition, amyloid deposits contain a number of non-fibrillar components that interact with amyloid f...
