Galactic open clusters （Ocs） that survive the early gas-expulsion phase are gradually de- stroyed over time by the action of disruptive dynamical processes. Their final evolutionary stages are characterized by a poorly populated concentration of stars called an open cluster remnant （OcR）. This study is devoted to assessing the real physical nature of the OcR candidate NGc 7193. GMOS/Gemini spectroscopy of 53 stars in the inner target region were obtained to derive radial velocities and at- mospheric parameters. We also employed photometric and proper motion data. The analysis method consists of the following steps：（i） analysis of the statistical resemblance between the cluster and a set of field samples with respect to the sequences defined in color-magnitude diagrams （cMDs）; （ii） a 5-dimensional iterative exclusion routine was employed to identify outliers from kinematical and posi- tional data; （iii） isochrone fitting to thes× （J - Ks） cMD of the remaining stars and the dispersion of spectral types along empirical sequences in the （J - H） × （H - Ks） diagram were checked. A group of stars was identified for which the mean heliocentric distance is compatible with that obtained via isochrone fitting and whose metallicities are compatible with each other. Fifteen of the member stars observed spectroscopically were identified together with another 19 probable members. Our results indi- cate that NGc 7193 is a genuine OcR, of a once very populous Oc, for which the following parameters were derived： d = 501±46 pc, t = 2.5±1.2 Gyr, （[Fe/H]） = -0.17±0.23 and E（b-V） = 0.05±0.05. Its luminosity and mass functions show depletion of low mass stars, confirming the OcR is in a dynam- ically evolved state.

The corpus cavernosum after treatment with dutasteride or finasteride： a histomorphometric study in a benign prostatic hyperplasia rodent model

引用

Asian Journal of Andrology 2018年第5期20卷 505-510页

作者： Marcello H A Da Silva Waldemar S costa francisco J b Sampaio Diogo b De Souza Urogenital Research Unit Rio de Janeiro State University Rio de Janeiro RJ 20551-030 Brazil

Erectile dysfunction is a common side effect of finasteride and dutasteride treatments. The objective of this study was to investigate the structural changes in the penis using a benign prostatic hyperplasia （bPH） rodent model treated with dutasteride or finasteride. Sixty male rats were divided into the following groups： c, untreated control rats; c ＋ D, control rats receiving dutasteride; c ＋ F, control rats receiving finasteride; H, untreated spontaneously hypertensive rats （SHRs）; H ＋ D, SHRs treated with dutasteride; and H ＋ F, SHRs treated with finasteride. Treatments were performed for 40 days, and penises were collected immediately thereafter. The organs were analyzed using histomorphometric methods to determine the cross-sectional penile area, as well as the surface density （Sv） of smooth muscle fibers, connective tissue, elastic system fibers, and sinusoidal spaces of the corpus cavernosum. The results were compared using a one-way ANOVA with bonferroni＇s posttest. Groups c ＋ D and c ＋ F had a significantly smaller penile cross-sectional area, but more elastic system fiber Sv compared to Group c. Group c ＋ D showed less smooth muscle Sv, and Group H showed more connective tissue but a smaller sinusoidal space Sv in the corpus cavernosum compared to Group c. Groups H ＋ D and H ＋ F had less smooth muscle Sv than Group H. Group H ＋ D also had more connective tissue and elastic system fiber Sv than Group H. both dutasteride and finasteride promoted penile modifications in the control rat penis, although this affect was ~reater in Group H animals. In this rodent model, dutasteride was the drug that most affected the corpus cavernosum.

characterization of cnidoscolus quercifolius Pohl bark root extract and evaluation of cytotoxic effect on human tumor cell lines

引用

Asian Pacific Journal of Tropical biomedicine 2018年第7期8卷 345-351页

作者： Paulo Fernando Machado Paredes Selene maia de Morais Fernando cesar Rodrigues brito Luiz francisco Wemmenson Goncalves Moura Patricia de Araujo Rodrigues Stephen Rathinaraj benjamin francisco Ernani Alves Magalhaes Eridan Orlando Pereira Tramontina Florean Maria Izabel Florindo Guedes Northeast biotechnology Network Graduate Program of Biotechnology State University of Ceara Itaperi campus Department of chemistry State University of Ceara Itaperi campus Laboratory of bioprospecting of Natural Products and biotechnology State University of CearaCECITEC

Objective: To evaluate the chemical components of active extract from cnidoscolus quercifolius root bark and its cytotoxic potential against several tumor strains. Methods: The high-performance liquid chromatography with diode-array detection and ~1H and ^(13)c nuclear magnetic resonance spectroscopy of the extract were used to distinguish the existence of possible functional groups in the root bark extract. The in vitro cytotoxic activity of methanol extract on human colon cancer cell lines was evaluated using OVcAR-8, SF-295, HcT-116, HL-60 strains and the samples were assessed by 3-(4,5-dimethylthiazol2-yl)-2,5-diphenyltetrazolium bromide method. Results: The analysis of nuclear magnetic spectra of the active chloroform fraction revealed the presence of absorptions bands correspondent to a mixture of favelines such as neofavelanone, deoxofaveline or methyl-faveline, which structures were confirmed by ultraviolet spectra upon high-performance liquid chromatography with diode-array detection analysis. The active fraction showed cytotoxic effects in the tested strains, HcT-116, SF-295, OVcAR-8 and HL-60 cells with Ic_(50) of 72 hours ranging from 4.95 to 15.23 μg/mL. conclusions: The results suggest that the substances present in faveleira(cnidoscolus quercifolius) root bark extract have a cytotoxic potential against several tumor lines, showing a broader antitumour potential, and in addition no adverse to healthy cells. Therefore, the root bark extract of cnidoscolus quercifolius has a possibility of use for anticarcinogenic therapies.
