Double-vessel coronary stenting via 5 french diagnostic catheters

The authors report on the use of 5 French diagnostic catheters to deliver a stent-on-a-wire system during a double vessel coronary intervention.

Acid and alkali etching of grit blasted zirconia: Impact on adhesion and osteogenic differentiation of MG63 cells in vitro

There is a need for evaluating zirconia surface modifications and their potential impact on the biological response of osteogenic cells. Grit blasted zirconia discs were either left untreated or underwent acid or alkaline etching. Adhesion and osteogenic differentiation of MG63 cells was determined after one week of culture. The macro-scaled roughness of the grit blasted zirconia discs, independent of the surface treatment, was within a narrow range and only slightly smoother than titanium discs. However, the alkaline- and acid-etching led to an increase of the micro-roughness of the surface. The surface modifications had no effect on cell spreading and did not cause significant change in the expression of differentiation markers. Thus, in this respective setting, morphologic changes observed upon treatment of grit blasted zirconia discs with acid or alkaline do not translate into changes in MG63 cell adhesion or differentiation and are comparable to findings with anodized titanium discs.

Coronary stenting through 4 French diagnostic catheter

A first case of coronary stent implantation through a 4 French diagnostic catheter is described.

The Modernity of la Mode: a History of the French Revolution Through the Lens of Fashion, Culture, and Identity

In my thesis, I explore the cultural history of the French Revolution and its relation to the modern era which ensued. Many historians have studied the French Revolution as it relates to culture, the rise of modernity, and fashion. I combine the unique histories of all three of these aspects to reach an understanding of the history of the French Revolution and fashion’s role in bringing about change. In the majority of literature of costume history, discussion of fashion surrounds its reflective properties. Many historians conclude fashion as a reflection of the broader cultural shifts that occurred during the Revolution. I, on the other hand, propose that fashion is an active force in bringing out cultural change during this time. In exploring fashion as a historical motivator, I examine the aesthetic world of fashion from 1740 to 1815, the modern system of cultural dissemination of fashion through particular historical heroes, and the rise of “taste” and its relation to modern identity. Through aesthetics, culture, and identity, I argue that fashion is a decisive force of culture in that it creates a visual world through which ideas form and communicate.

Comparative Analysis of Russian and French Prosodies: Theoretical, Experimental and Applied Aspects"

Experience shows that in teaching the pronunciation of a foreign language, it is the native syllable stereotype that resists correction most strongly. This is because the syllable is the basic unit of the perception and production of speech, and syllabic production is highly automatic and to some degree determines the prosody of speech at all levels: accent, rhythm, phrase, etc. The results of psycho-physiological studies show that the human acoustic analyser is a typical contemplator organ and new acoustic qualities are perceived through their inclusion into the already existing system of values characteristic to the mother tongue. This results in the adaptation of the perception and so production of foreign speech to native patterns. The less conscious the perception of the unit and the more 'primitive' its status, the greater the degree of its auditory assimilation, and the syllable is certainly among the less controllable linguistic units. The group carried out a complex investigation of the French and Russian languages at the level of syllable realisation, focusing on the stressed syllable of both open and closed types. The useful acoustic characteristics of the French/Russian syllable pattern were determined through identifying a typical syllable pattern within the system of each of the two languages, comparing these patterns to establish their contrasting features, and observing and systematising deviations from the pattern typical of the French/Russian language teaching situation. The components of the syllable pattern shown to need particular attention in teaching French pronunciation to Russian native speakers were intensity, fundamental frequency, and duration. The group then developed a method of correction which combines the auditory and visual canals of sound signal perception and tested this method with groups of Russian students of different levels.
