Platinum preparations in the treatment of trophoblastic tumors

The N.N. Blokhin Russian Cancer Research Center, Russian Academy of Medical Sciences, has developed and used new polychemotherapy regimens including platinum preparations for the treatment of patients with trophoblastic tumors. A cysplatin + ethoposide or carboplatin + ethoposide (CyE/CaE) combination was used as second-line chemotherapy in methotrexate-resistant locally advanced form (Stages I-II) of the disease. A cysplatin or carboplatin + methotrexate + dactinomycin + vincristine) (CyMDV/CaMDV) regimen was used as first-line therapy in patients with disseminated (Stage III-IV) disease and as second-line therapy in patients with its resistant form (Stages III-IV). The CyE/CaE regimen could cure 21 patients with Stages I-II without surgical intervention. When the CyMDV/CaMDV regimen was used as first-line therapy in 24 patients with Stages III-IV disease, of them 21 (87.5%) patients achieved a complete therapeutic effect, they all have been survivors to the present time. The CyMDV/CaMDV regimen used as second-line chemotherapy in patients with the resistant form turned out to be effective in 5 (83.3%) of 6 cases. The follow-up lasted > 3 years.The benefit of the developed regimens including platinum preparations is that they are effective, less toxic, require long hospitalization and are technically simpler, which allows them to be used in the outpatient setting of the wide oncological network

THE DAILY 110 MHZ SKY SURVEY (BSA FIAN): ON-LINE DATABASE, SCIENCE AIMS AND FIRST RESULTS OF DATA PROCESSING

From 2012 on radio telescope BSA FIAN multi beams diagram was started. It capable at July 2014 daily observing by 96 beams in declination -8 .. 42 degrees in the frequency band 109-111.5 MHz. The number of frequency bands are from 6 to 32, the time constant are from 0.1 to 0.0125 sec. In receiving mode with 32 band (plus one common band) with a time constant of 12.5 ms (80 times per second) respectively produced 33x96x80 four byte real and so daily we produced 87.5 Gbt (yearly to 32 Tbt). These data are enormous opportunities for both short and long-term monitoring of various classes of radio sources (including radio transients) and for space weather and the Earth's ionosphere monitoring, for search for different classes of radio sources, etc. The base aims of our work are: a) to obtain new scientific data on different classes of discrete radio sources, the construction of physical models and their evolution - obtained on the basis of the clock continuous digital sky radio monitoring at frequency 109- 111.5 MHz and cross-analysis of data from third-party reviews on other frequencies; c) launch the streaming data on various types of highperformance computing systems, including to create a public system of distributed computing for thousands of users on the basis of BOINC technology. The BOINC client for astronomical data from the monitoring survey of the big part of entire sky almost have not analogies. We have some first science results (new pulsars, and some new type of radiosources)

Fixing incremental computation: derivatives of fixpoints, and the recursive semantics of datalog

Incremental computation has recently been studied using the concepts of change structures and derivatives of programs, where the derivative of a function allows updating the output of the function based on a change to its input. We generalise change structures to change actions, and study their algebraic properties. We develop change actions for common structures in computer science, including directed-complete partial orders and Boolean algebras. We then show how to compute derivatives of fixpoints. This allows us to perform incremental evaluation and maintenance of recursively defined functions with particular application generalised Datalog programs. Moreover, unlike previous results, our techniques are modular in that they are easy to apply both to variants of Datalog and to other programming languages
