RATAN-600 7.6-cm Deep Sky Strip Surveys at the Declination of the SS433 Source During the 1980-1999 Period. Data Reduction and the Catalog of Radio Sources in the Right-Ascension Interval 7h < R.A. < 17h

We use two independent methods to reduce the data of the surveys made with RATAN-600 radio telescope at 7.6 cm in 1988-1999 at the declination of the SS433 source. We also reprocess the data of the "Cold" survey (1980-1981). The resulting RCR (RATAN COLD REFINED) catalog contains the right ascensions and fluxes of objects identified with those of the NVSS catalog in the right-ascension interval 7h < R.A. < 17h. We obtain the spectra of the radio sources and determine their spectral indices at 3.94 and 0.5 GHz. The spectra are based on the data from all known catalogs available from the CATS, Vizier, and NED databases, and the flux estimates inferred from the maps of the VLSS and GB6 surveys. For 245 of the 550 objects of the RCR catalog the fluxes are known at two frequencies only: 3.94 GHz (RCR) and 1.4 GHz (NVSS). These are mostly sources with fluxes smaller than 30 mJy. About 65% of these sources have flat or inverse spectra (alpha > -0.5). We analyze the reliability of the results obtained for the entire list of objects and construct the histograms of the spectral indices and fluxes of the sources. Our main conclusion is that all 10-15 mJy objects found in the considered right-ascension interval were already included in the decimeter-wave catalogs.Comment: 26 pages, 18 figure

Catalog of Radio Galaxies with z>0.3. I:Construction of the Sample

The procedure of the construction of a sample of distant ($z>0.3$) radio galaxies using NED, SDSS, and CATS databases for further application in statistical tests is described. The sample is assumed to be cleaned from objects with quasar properties. Primary statistical analysis of the list is performed and the regression dependence of the spectral index on redshift is found.Comment: 9 pages, 6 figures, 2 table

Correlation properties of the maps of the NVSS survey and WMAP ILC

In this paper we study one-dimensional sections of the maps of WMAP ILC and of the NVSS survey on scale lengths of 0.75, 3, 4.5, and 6.75 degrees and analyze the correlation properties of the sections. On these maps we identify the domains where the absolute value of the correlation coefficient exceeds 0.5. The catalog of such domains is presented. It is shown that the number of the domains agrees with the number of such domains on simulated maps and this fact may be indicative of just statistical agreement of the arrangement of the domains considered.Comment: 8 pages, 2 figure

Multiband Study of Radio Sources of the RCR Catalogue with Virtual Observatory Tools

We present early results of our multiband study of the RATAN Cold Revised (RCR) catalogue obtained from seven cycles of the “Cold” survey carried with the RATAN-600 radio telescope at 7.6 cm in 1980-1999, at the declination of the SS 433 source. We used the 2MASS and LAS UKIDSS infrared surveys, the DSS-II and SDSS DR7 optical surveys, as well as the USNO-B1 and GSC-II catalogues, the VLSS, TXS, NVSS, FIRST and GB6 radio surveys to accumulate information about the sources. For radio sources that have no detectable optical candidate in optical or infrared catalogues, we additionally looked through images in several bands from the SDSS, LAS UKIDSS, DPOSS, 2MASS surveys and also used co-added frames in different bands. We reliably identified 76% of radio sources of the RCR catalogue. We used the ALADIN and SAOImage DS9 scripting capabilities, interoperability services of ALADIN and TOPCAT, and also other Virtual Observatory (VO) tools and resources, such as CASJobs, NED, Vizier, and WSA, for effective data access, visualization and analysis. Without VO tools it would have been problematic to perform our study

Результаты применения этравирина в течение 48 недель у пациентов в Санкт-Петербурге в реальной клинической практике

The aim of the work was to evaluate the efficacy, safety and tolerability of etravirine-containing regimens in patients with treatment experience in real clinical practice.Materials and methods. A retrospective analysis of 300 outpatient records of HIV-infected patients with treatment experience, which were converted to regimens containing etravirine (ETR) as the third component, was performed. The reasons for switching to ETR-containing regimens were adverse events, comorbidities, and virological failure. The main criterion for the effectiveness of the scheme was the proportion of patients with an undetectable level of viral load at 48 weeks of treatment. Additional criteria for evaluating the effectiveness and safety of the scheme were the dynamics of the number of CD4-lymphocytes, the frequency and nature of adverse reactions.Results. The proportion of patients with virologic suppression less than 50 kop/mL was 83% versus 77,3% at the time of switching (p&lt;0.005). The percentage of patients with CD4-lymphocytes level &gt;500 ctlls/um increased from 40,3% to 58%, and the percentage of patients with CD4 level &lt;200 cells/um decrease more than twice from 13% to 6% (p&lt;0.005). The mean level os ALT decreased significantly from 47,52±66,45 units/L to 42,65±55,18 units/L (p=0,019). The average level of total cholesterol decreased by 8.7% from 5,64±1,37 mmol/L to 5.15±0.98 mmol/L (p&lt;0,001). The average BMI after switching to ETR did not change and amounted to 24,07±4,07, 24,2±4,05, respectively (p=0,347).Conclusions. The results of this study confirm that etravirine is well tolerated and may be an option for patients who have HIV RNA suppression on ART but develop adverse reactions, and may also be part of a second-line ART regimen in patients who fail first-line regimen.Цель: оценка эффективности, безопасности и переносимости схем, содержащих этравирин, у пациентов с опытом лечения в реальной клинической практике.Материалы и методы. Проведен ретроспективный анализ 300 амбулаторных карт ВИЧ-инфицированных пациентов с опытом лечения, которые были переведены на схемы, содержащие в качестве 3-го компонента препарат этравирин (ETR, ETV). Причинами переключения на ETR-содержащие схемы были нежелательные явления, сопутствующие заболевания, а также вирусологическая неэффективность. Основным критерием эффективности схемы явилась доля пациентов с неопределяемым уровнем вирусной нагрузки на 48-й неделе лечения. Дополнительными критериями оценки эффективности и безопасности схемы являлись динамика количества CD4+-лимфоцитов, частота и характер нежелательных побочных реакций.Результаты. Доля пациентов с вирусологической супрессией менее 50 коп/мл составила 83% против 77,3% на момент переключения (p &lt;0,005). Доля пациентов, имеющих уровень CD4+-лимфоцитов более 500 кл/мкл., возросла с 40,3% до 58%, а доля пациентов, имеющих уровень CD4+-лимфоцитов менее 200 кл/мкл, уменьшилась более чем в 2 раза с 13% до 6% (p&lt;0,005). Получено достоверное снижение среднего уровня АЛТ с 47,52±66,45 Ед/л до 42,65±55,18 Ед/л (p=0,019). Средний уровень общего холестерина снизился на 8,7% с 5,64±1,37 ммоль/л до 5,15±0,98 ммоль/л (p&lt;0,001). Средний ИМТ после переключения на ETV не изменился и составил 24,07±4,07, 24,2±4,05 соответственно (p=0,347).Выводы. Результаты этого исследования подтверждают, что этравирин хорошо переносится и может быть вариантом для пациентов, у которых наблюдается супрессия РНК ВИЧ на АРТ, но развились побочные реакции, а также может стать частью схемы АРТ второго ряда у пациентов с неэффективностью схемы первого ряда
