Triple-negative breast cancer (TNBC) is a highly malignant tumor histotype which lacks effective targeted therapies, thereby being considered as the most aggressive form of breast carcinoma. To identify novel compounds which could counteract TNBC cell growth, we explored the in vitro effects of crude extracts and <
Treatment of Dimpling from Cellulite.
2018
Background:. Cellulite can be seen on the skin in widespread alterations of the skin surface and dimpling. The purpose of this study was to assess the effectiveness and safety of the manual subcision technique to treat dimpling from cellulite, using a specific class IIA medical device (Celluerase). Methods:. The multi-center observational study assessed 200 women treated in a single session for different dimpling, using manual subcision administered by Celluerase. Aesthetic outcomes were evaluated by the authors, and the patients assessed satisfaction levels. Results:. Two hundred women between 20 and 55 years were treated. The medical evaluation of patients saw improvements with an average…
Immunotherapy With Human Gamma Delta T Cells—Synergistic Potential of Epigenetic Drugs?
2018
Epigenetics has emerged as one of the fastest growing concepts, adding more than 45 new publications every day, spreading through various fields ( 1). Conrad Waddington coined the term “epigenetics” in 1942; however, a multitude of definitions has been endorsed by different researchers. In essence, Waddington’s definition of “epigenetics” and its redefinition by Holiday is at the heart of cellular function. Hence, it is obvious that epigenetic regulation plays a central role also in the specification, differentiation, and functional plasticity of T lymphocytes ( 2). T-cell fate decision in progenitor cells, functional CD4 T-cell plasticity, CD8 T-cell differentiation, but also T-cell memory…
Laser cleaning of oxide iron layer : efficiency enhancement due to electrochemical induced absorptivity change
1999
Laser cleaning experiments exhibited a higher cleaning efficiency of the laser cleaning upon application of electrochemical potential on an oxidised iron surface. The objective of this study is to clarify the role of such an electrochemical control on cleaning efficiency. Therefore a study by optical spectrometry at normal incidence in the relevant conditions was performed. From these measurements the optical parameters n and k were deduced. While n is mainly not affected, k changes for a factor of 10 upon application of an electrochemical potential. These results explain the differences in laser cleaning efficiency due to the modified absorption length.
How consistent are the transcriptome changes associated with cold acclimation in two species of the Drosophila virilis group?
2015
This work was financially support by a Marie Curie Initial Training Network grant, “Understanding the evolutionary origin of biological diversity” (ITN-2008–213780 SPECIATION), grants from the Academy of Finland to A.H. (project 132619) and M.K. (projects 268214 and 272927), a grant from NERC, UK to M.G.R. (grant NE/J020818/1), and NERC, UK PhD studentship to D.J.P. (NE/I528634/1). For many organisms the ability to cold acclimate with the onset of seasonal cold has major implications for their fitness. In insects, where this ability is widespread, the physiological changes associated with increased cold tolerance have been well studied. Despite this, little work has been done to trace chang…
A Telegraph for China: The Attempted Application of Caselli’s Pantelegraph to Transmit Chinese Characters, 1856−87
2016
In 1872 the Shanghai-based newspaper Shenbao described an invention by Giovanni Caselli that allowed the production of telegraphic messages containing Chinese characters, the ‘pantelegraph’, an ancestor of the fax, reproducing manu- scripts, images and symbols, and, as such, totally suitable for Chinese telegraphy. In 1863, the Italian inventor had shown his invention to a legation of Chinese diplomats in France, producing some impressive Chinese transmissions, the caselligrammi. The envoys reported this information back home, but for some reasons a commercial contact was only set twenty years later. Although in many ways this seemed to be a perfectly suitable solution for the telegraphic c…
Chiral anomalies in even and odd dimensions
1985
Odd dimensional Yang-Mills theories with an extra ‘topological mass” term, defined by the Chern-Simons secondary characteristic, are discussed. It is shown in detail how the topological mass affects the equal time charge commutation relations and how the modified commutation relations are related to non-abelian chiral anomalies in even dimensions. We also study the SU(3) chiral model (Wess-Zumino model) in four dimensions and we show how a gauge invariant interaction with an external SU(3) vector potential can be defined with the help of the Chern-Simons characteristic in five dimensions.
Effects of eight weeks of physical training on physical performance and heart rate variability in children
2017
Kraama, Liisa. 2013. Effects of eight weeks physical training on physical performance and heart rate variability in children. University of Jyvaskyla, Department of Biology of Physical Activity. Master’s Thesis in Exercise Physiology. 52 pp. Physical activity and aerobic capacity have decreased among children and adolescents during the last decades. Physically active adults have been shown to have higher heart rate variability (HRV) than less active adults. In adults training-induced changes in physical performance have been shown to be related to increase in HRV, especially in high frequency component (HF), which is a marker of parasympathetic activity. The purpose of this study was to exa…

Civil Society in the 2004 Romanian Elections: Watchdog, Involved Arbiter or Political Actor?
2010
Abstract Civil society has proven outstanding capacities of involvement in the 2004 general elections in Romania and put a remarkable pressure on the political society. This paper aims to discuss the consequences of such involvement for both the political and civil society. We also investigate the conditions that have favoured a successful challenge of the main political actors by the most visible civic advocacy organizations. Further, we inquire how deep can an actor from the civil society go into the lands of the political society. In the end, we weight the achievements and the failures of civil society’s active involvement in the game of elections.
