    The research is devoted to the rational design of new non-steroidal anti-inflammatory drugs (NSAIDs) using the 4-thiazolidinoneΒ β€œcore”. A series of 2-(4-R-2-formylphenoxy)-N-(R’-phenyl)acetamides has been synthesized from salicylicΒ aldehydes for structural modifications of basic heterocycles. The aldehydes obtained are active carbonyl agents andΒ suitable β€œbuilding blocks” for the focused synthesis of biologically active compounds. Ylidene derivatives of 2-thioxo-4-thiazolidinone and 2-(4-hydroxyphenyl)imino-4-thiazolidone have been synthesized in the Knoevenagel reactionΒ conditions. The one-pot reaction between 3(5)-merkapto-1,2,4-triazoles, chloroacetic acid and the salicylic aldehydeΒ derivatives synthesized have been used for the synthesis of 5-ylidene-thiazolo[3,2-b][1,2,4]triazol-6-one. ParametersΒ of acute toxicity and the anti-exudative activity (carrageenin paw edema test) have been studied for the ylidene derivativesΒ synthesized. It has been found that all compounds synthesized demonstrate the anti-exudative activity, andΒ some β€œstructure – acute toxicity – anti-exudative activity” relationships have been analyzed. Based on the results ofΒ in vivo studies the lead compound – 4-{2-[4-chloro-2-(6-oxothiazolo[3,2-b][1,2,4]triazole-5-ylidenemethyl)-phenoxy]-Β acetylamino}-benzoic acid ethyl ester that demonstrates the anti-exudative activity equivalent to the classic NSAIDΒ Diclofenac has been identified, it has a low level of toxicity and can be recommended for the profound study.ИсслСдованиС посвящСно Ρ€Π°Ρ†ΠΈΠΎΠ½Π°Π»ΡŒΠ½ΠΎΠΌΡƒ Π΄ΠΈΠ·Π°ΠΉΠ½Ρƒ Π½ΠΎΠ²Ρ‹Ρ… нСстСроидных ΠΏΡ€ΠΎΡ‚ΠΈΠ²ΠΎΠ²ΠΎΡΠΏΠ°Π»ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… срСдств (ΠΠŸΠ’Π‘) с использованиСм 4-Ρ‚ΠΈΠ°Π·ΠΎΠ»ΠΈΠ΄ΠΈΠ½ΠΎΠ½ΠΎΠ²ΠΎΠ³ΠΎ «каркаса».

    Direct Imaging of Fine Structures in Giant Planet Forming Regions of the Protoplanetary Disk around AB Aurigae

    Full text link
    We report high-resolution 1.6 \micron polarized intensity (PIPI) images of the circumstellar disk around the Herbig Ae star AB Aur at a radial distance of 22 AU (0."150."15) up to 554 AU (3.""85), which have been obtained by the high-contrast instrument HiCIAO with the dual-beam polarimetry. We revealed complicated and asymmetrical structures in the inner part (≲\lesssim140 AU) of the disk, while confirming the previously reported outer (rr ≳\gtrsim200 AU) spiral structure. We have imaged a double ring structure at ∼\sim40 and ∼\sim100 AU and a ring-like gap between the two. We found a significant discrepancy of inclination angles between two rings, which may indicate that the disk of AB Aur is warped. Furthermore, we found seven dips (the typical size is ∼\sim45 AU or less) within two rings as well as three prominent PIPI peaks at ∼\sim40 AU. The observed structures, including a bumpy double ring, a ring-like gap, and a warped disk in the innermost regions, provide essential information for understanding the formation mechanism of recently detected wide-orbit (rr >>20 AU) planets.Comment: 12 pages, 3 figure

    Imaging of a Transitional Disk Gap in Reflected Light: Indications of Planet Formation Around the Young Solar Analog LkCa 15

    Get PDF
    We present H- and Ks-band imaging data resolving the gap in the transitional disk around LkCa 15, revealing the surrounding nebulosity. We detect sharp elliptical contours delimiting the nebulosity on the inside as well as the outside, consistent with the shape, size, ellipticity, and orientation of starlight reflected from the far-side disk wall, whereas the near-side wall is shielded from view by the disk's optically thick bulk. We note that forward-scattering of starlight on the near-side disk surface could provide an alternate interpretation of the nebulosity. In either case, this discovery provides confirmation of the disk geometry that has been proposed to explain the spectral energy distributions (SED) of such systems, comprising an optically thick outer disk with an inner truncation radius of ~46 AU enclosing a largely evacuated gap. Our data show an offset of the nebulosity contours along the major axis, likely corresponding to a physical pericenter offset of the disk gap. This reinforces the leading theory that dynamical clearing by at least one orbiting body is the cause of the gap. Based on evolutionary models, our high-contrast imagery imposes an upper limit of 21 Jupiter masses on companions at separations outside of 0.1" and of 13 Jupiter masses outside of 0.2". Thus, we find that a planetary system around LkCa 15 is the most likely explanation for the disk architecture.Comment: 5 pages, 4 figures, accepted for publication in ApJ Letters.

    New Techniques for High-Contrast Imaging with ADI: the ACORNS-ADI SEEDS Data Reduction Pipeline

    Get PDF
    We describe Algorithms for Calibration, Optimized Registration, and Nulling the Star in Angular Differential Imaging (ACORNS-ADI), a new, parallelized software package to reduce high-contrast imaging data, and its application to data from the SEEDS survey. We implement several new algorithms, including a method to register saturated images, a trimmed mean for combining an image sequence that reduces noise by up to ~20%, and a robust and computationally fast method to compute the sensitivity of a high-contrast observation everywhere on the field-of-view without introducing artificial sources. We also include a description of image processing steps to remove electronic artifacts specific to Hawaii2-RG detectors like the one used for SEEDS, and a detailed analysis of the Locally Optimized Combination of Images (LOCI) algorithm commonly used to reduce high-contrast imaging data. ACORNS-ADI is written in python. It is efficient and open-source, and includes several optional features which may improve performance on data from other instruments. ACORNS-ADI requires minimal modification to reduce data from instruments other than HiCIAO. It is freely available for download at www.github.com/t-brandt/acorns-adi under a BSD license.Comment: 15 pages, 9 figures, accepted to ApJ. Replaced with accepted version; mostly minor changes.

    Near-Infrared Multi-Band Photometry of the Substellar Companion GJ 758 B

    Full text link
    GJ 758 B is a cold (~600K) companion to a Sun-like star at 29 AU projected separation, which was recently detected with high-contrast imaging. Here we present photometry of the companion in seven photometric bands from Subaru/HiCIAO, Gemini/NIRI and Keck/NIRC2, providing a rich sampling of the spectral energy distribution in the 1-5 micron wavelength range. A clear detection at 1.58 micron combined with an upper limit at 1.69 micron shows methane absorption in the atmosphere of the companion. The mass of the companion remains uncertain, but an updated age estimate indicates that the most likely mass range is ~30-40 Mjup. In addition, we present an updated astrometric analysis that imposes tighter constraints on GJ 758 B's orbit and identifies the proposed second candidate companion, "GJ 758 C", as a background star.Comment: 10 pages, 4 figures, accepted for publication in ApJ Letters. New version: Corrected a few numbers in the astrometry section (which were already correct in the print version, but were based on an outdated simulation in the astro-ph version

    In the era of personalized treatment, oncologists are striving to tailor medical treatment to the characteristics of the individual patient, emphasizing the importance of a continuous search for accurate biomarkers. Prognostic biomarkers reflect the intricate underlying biology that enables cancer to progress. Intratumoural heterogeneity includes genetic, epigenetic and functional heterogeneity. Genetic intratumour heterogeneity is a consequence of clonal evolution and a cause of desease progression. Herewith specific mutations are associated with particular stages of tumour development, correlates with specific histopathological disease stages. Many patients with prostate cancer have disease recurrence after resection of the tumor despite adjuvant therapy, while some patients dont have a relapse despite the absence of treatment. So the reassessment of the current criteria and better prognostic and predictive biomarkers for the selection of patients who might benefit from adjuvant chemotherapy are urgently needed. A prognostic biomarker reflects the natural history of the tumor and provides information on the likely outcome and prognosis, independent of a specific treatment. Predictive biomarkers indicate the sensitivity or resistance of the tumor to a given treatment. Some markers can be both prognostic and predictive. Gene mutations and epigenetic changes that modify the intracellular signaling pathways may be important factors in oncogenesis. In this context, oncogenes, genes-tumor suppressors and miRNAs have attracted attention as potential biomarkers and regulators of oncogenesis and evaluate in clinical trials.Π’ эпоху пСрсонализированного лСчСния ΠΎΠ½ΠΊΠΎΠ»ΠΎΠ³ΠΈ стрСмятся Π°Π΄Π°ΠΏΡ‚ΠΈΡ€ΠΎΠ²Π°Ρ‚ΡŒ Π΅Π³ΠΎ ΠΊ особСнностям ΠΊΠΎΠ½ΠΊΡ€Π΅Ρ‚Π½ΠΎΠ³ΠΎ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚Π°, подчСркивая Π²Π°ΠΆΠ½ΠΎΡΡ‚ΡŒ Π½Π΅ΠΏΡ€Π΅Ρ€Ρ‹Π²Π½ΠΎΠ³ΠΎ поиска Ρ‚ΠΎΡ‡Π½Ρ‹Ρ… Π±ΠΈΠΎΠΌΠ°Ρ€ΠΊΠ΅Ρ€ΠΎΠ².

    The Moving Group Targets of the Seeds High-Contrast Imaging Survey of Exoplanets and Disks: Results and Observations from the First Three Years

    Get PDF
    We present results from the first three years of observations of moving group (MG) targets in the Strategic Exploration of Exoplanets and Disks with Subaru (SEEDS) high-contrast imaging survey of exoplanets and disks using the Subaru telescope. We achieve typical contrasts of (is) approximately10(exp 5) at 1" and (is) approximately 10(exp 6) beyond 2" around 63 proposed members of nearby kinematic MGs. We review each of the kinematic associations to which our targets belong, concluding that five, beta Pictoris ((is) approximately 20 Myr), AB Doradus ((is) approximately 100 Myr), Columba ((is) approximately 30 Myr), Tucana-Horogium ((is) approximately 30 Myr), and TW Hydrae ((is) approximately 10 Myr), are sufficiently well-defined to constrain the ages of individual targets. Somewhat less than half of our targets are high-probability members of one of these MGs. For all of our targets, we combine proposed MG membership with other age indicators where available, including Ca ii HK emission, X-ray activity, and rotation period, to produce a posterior probability distribution of age. SEEDS observations discovered a substellar companion to one of our targets, kappa And, a late B star. We do not detect any other substellar companions, but do find seven new close binary systems, of which one still needs to be confirmed. A detailed analysis of the statistics of this sample, and of the companion mass constraints given our age probability distributions and exoplanet cooling models, will be presented in a forthcoming paper
