This monograph is about an artistic journey set off eighty years ago in the nascent Republic China. It charged into the “impossible” realm--nudity--in the grand Chinese tradition and turned it, if somewhat by accident, into the “possible”, unveiling perhaps the most censored body in the art world. The journey has since been progressing--at times in twists and turns--although the artist, Xu Beihong, who initiated it had died 14 years after the set-off--never had a chance to reap results--leaving behind a legacy largely misunderstood and undervalued. Xu Beihong, a Paris academy-trained Chinese painter at the turn of the 20th century, professed to reform a declining art at a time when China was seeking new political and cultural lights shed by the West. With a stern belief in the Western realism, Xu had brought home not just the realist techniques but also the classic iconography of the nude dated back to the Renaissance Venus. Xu had not offered us voluminous art works in this respect,...4950 Руб.
When compared to MTA cells, MTB-01 cells were susceptible to risedronateinduced apoptosis, had decreased ability to bind to risedronate-treated bone, and did not produce MMP-2 or MMP-9 proteases. MTA cells were less susceptible to risedronateinduced apoptosis and produced MMP-2. Additionally, adhesion of MTA cells to bone matrix was not diminished by risedronate treatment. Our results suggest that the nonresponsive nature of the MTA cell line may be due to MMP-2 production (possibly allowing ongoing destruction of risedronate-treated bone), continued adhesion to risedronate-treated bone matrix, and decreased susceptibility to risedronate-induced apoptosis.5225 Руб.

Corticotomy-assisted orthodontic treatment is an established and efficient orthodontic technique that has gradually gained popularity as an adjunct treatment option for the orthodontic treatment of adults. It involves selective alveolar decortication in the form of decortication lines and cortical perforations performed around the teeth that are to be moved. It is done to induce a state of increased tissue turnover and a transient osteopenia, which is followed by a faster rate of orthodontic tooth movement. This technique has several advantages, including faster tooth movement, shorter treatment time, safer expansion of constricted arches, enhanced post-orthodontic treatment stability and extended envelope of tooth movement. Alveolar augmentation of labial and lingual cortical plates are also used in an effort to enhance and strengthen the periodontium, reasoning that the addition of bone to alveolar housing of the teeth, using modern bone grafting techniques, ensures proper root...4535 Руб.
