Background: Patients with stem cell myeloproliferative disorders have a particularly poor prognosis and limited treatment options, i.e. mainly aggressive chemotherapy or allogeneic stem cell transplantation. In 2004, Chen et al. reported a patient presenting a t(8;13) (p11;q12) cytogenic anomaly who responded positively to treatment with PKC412 (midostaurin), an oral multi-targeted tyrosine kinase inhibitor. Here, we report a second case treated with the above-mentioned drug. Patient: A 71-year-old woman was diagnosed as having chronic myelogenous leukaemia with eosinophilia secondary to t(8;13) with FGFR1 involvement. Due to her age, an allogeneic stem cell transplantation was not possible. Treatment: A treatment combining aggressive chemotherapy and midostaurin was explored. The patient received one cycle of hyper-CVAD chemotherapy followed by maintenance therapy with midostaurin. A relapse occurred after six months, and she was treated with four more cycles of hyper-CVAD chemotherapy. The patient entered a complete clinical, haematological and cytogenetic remission. A maintenance therapy with midostaurin continued for four months until she developed a chemoresistant relapse followed by acute leukaemia. Conclusion: This is the second case of a t(8;13) myeloid and lymphoid neoplasm with FGFR1 abnormalities treated successfully with midostaurin. Midostaurin is administered orally, allows for outpatient care and in this case showed only occasional and minimal side effects. The combination of hyper-CVAD and midostaurin extended survival by 21 months without allogeneic transplantation. This case further supports the possibility of using midostaurin for the treatment of other diseases with FGFR1 dysregulations; however, specific clinical trials are needed to confirm this hypothesis.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...

Fermented Brown Sugar Residue Prolongs the Caenorhabditis elegans Lifespan via DAF-16

Fermented brown sugar residue (FBSR) is generated in the course of purifying biomass ethanol from the yeast fermentation products of brown sugar. It contains abundant nutrition and is used in various industrial applications including as fertilizer and feed. Meanwhile, brown sugar has attracted attention as a health food and is thought to prevent cardiovascular diseases, hypertension, and brain stem diseases. Furthermore, polyphenol, contained in brown sugar, reduces oxidative stress and inhibits glucose absorption. DAF-16 is a transcription factor regulated downstream of the insulin signaling pathway and is one of the main factors contributing to aging and lifespan in C. elegans . Therefore, to determine the precise roles of the DAF-16 transcription factor in stress tolerance and life span, it is necessary to elucidate the signaling pathways involved in DAF-16 activation. This study was designed to elucidate the molecular mechanisms controlling the physiological stress toleran...
