Sweet orange ( Citrus sinensis), one of the most important fruit crops worldwide, may suffer from disease symptoms induced by virus infections, thus resulting in dramatic economic losses. Here, we show that the infection of sweet orange plants with two isolates of Citrus psorosis virus ( CPsV) expressing different symptomatology alters the accumulation of a set of endogenous microRNAs ( miRNAs). Within these miRNAs, miR156, miR167 and miR171 were the most down-regulated, with almost a three-fold reduction in infected samples. This down-regulation led to a concomitant up-regulation of some of their targets, such as Squamosa promoter-binding protein-like 9 and 13, as well as Scarecrow-like 6. The processing of miRNA precursors, pre-mi R156 and pre-mi R171, in sweet orange seems to be affected by the virus. For instance, virus infection increases the level of unprocessed precursors, which is accompanied by a concomitant decrease in mature species accumulation. miR156 a primary transcript accumulation remained unaltered, thus strongly suggesting a processing deregulation for this transcript. The co-immunoprecipitation of viral 24 K protein with pre-mi R156 a or pre-mi R171 a suggests that the alteration in the processing of these precursors might be caused by a direct or indirect interaction with this particular viral protein. This result is also consistent with the nuclear localization of both miRNA precursors and the CPsV 24 K protein. This study contributes to the understanding of the manner in which a virus can alter host regulatory mechanisms, particularly miRNA biogenesis and target expression. [ABSTRACT FROM AUTHOR]

- Abstract
El presente trabajo de grado tiene como objetivo: Identificar los factores que influyen en el establecimiento de relaciones interpersonales en siete (7) participantes colombianos con diferentes discapacidades físicas del departamento de Cundinamarca. Para cumplir el objetivo se realiza una revisión conceptual sobre discapacidad física e inclusión. La investigación es de carácter cualitativo con enfoque fenomenológico hermenéutico y se posiciona desde el paradigma de las teorías de la discapacidad. Asimismo, incluye un estudio instrumental de corte psicométrico para la evaluación de una plataforma digital que surge en el desarrollo de la investigación. Se entrevistaron tres grupos de participantes: personas con discapacidad, sus familiares y/o cercanos, y personas sin discapacidad; analizando los factores ambientales, culturales, personales y familiares que inciden en el establecimiento de relaciones interpersonales. Se obtiene como conclusión, que siguen existiendo actitudes discriminatorias sutiles en Colombia basadas en un paradigma tradicional, que interfieren en su desarrollo psicosocial.

- Abstract
The title compound, C
29 H46 O3 , is a steroid synthesized through a rearrangement of a sarsasapogenin derivative in acidic medium. The newly formed ring F is a tetra-hydro-2 H -pyran heterocycle substituted by two methyl groups placed in equatorial positions. This ring displays a chair conformation, while di-hydro-furan ring E , to which it is bonded, has an envelope conformation. The mol-ecules are associated by weak O-H⋯O hydrogen bonds to form chains running in the [101] direction in the crystal., (© Guerrero-Luna et al. 2023.)- Published

- Abstract
Sweet orange (Citrus sinensis), one of the most important fruit crops worldwide, may suffer from disease symptoms induced by virus infections, thus resulting in dramatic economic losses. Here, we show that the infection of sweet orange plants with two isolates of Citrus psorosis virus (CPsV) expressing different symptomatology alters the accumulation of a set of endogenous microRNAs (miRNAs). Within these miRNAs, miR156, miR167 and miR171 were the most down-regulated, with almost a three-fold reduction in infected samples. This down-regulation led to a concomitant up-regulation of some of their targets, such as Squamosa promoter-binding protein-like 9 and 13, as well as Scarecrow-like 6. The processing of miRNA precursors, pre-miR156 and pre-miR171, in sweet orange seems to be affected by the virus. For instance, virus infection increases the level of unprocessed precursors, which is accompanied by a concomitant decrease in mature species accumulation. miR156a primary transcript accumulation remained unaltered, thus strongly suggesting a processing deregulation for this transcript. The co-immunoprecipitation of viral 24K protein with pre-miR156a or pre-miR171a suggests that the alteration in the processing of these precursors might be caused by a direct or indirect interaction with this particular viral protein. This result is also consistent with the nuclear localization of both miRNA precursors and the CPsV 24K protein. This study contributes to the understanding of the manner in which a virus can alter host regulatory mechanisms, particularly miRNA biogenesis and target expression., (© 2015 BSPP and John Wiley & Sons Ltd.)

- Abstract
Diosgenone [(20S,22R,25R)-spirost-4-en-3-one, C(27)H(40)O(3)] has been proposed as a new therapeutic alternative for the treatment of malaria. The first X-ray structure report for diosgenone was by Piro et al. [(2002). Z. Naturforsch. Teil C, 57, 947-950] in the space group P2(1) (Z' = 2). We now report a new polymorph in the same space group, with two mol-ecules in the asymmetric unit. Both mol-ecules have similar conformations, characterized by a skewed envelope A ring, which contains the C=C bond conjugated with the ketone functionality at C3. The dimorphism results from a modification of the relative orientation of the mol-ecules in the asymmetric unit: two independent mol-ecules were arranged anti-parallel in the Piro report, while they are parallel in the present determination.

- Abstract
Purpose: To study the fate of Müller's glia following experimental retinal detachment, using a "pulse/chase" paradigm of bromodeoxyuridine (BrdU) labeling for the purpose of understanding the role of Müller cell division in subretinal scar formation., Methods: Experimental retinal detachments were created in pigmented rabbit eyes, and 3 days later 10 microg of BrdU was injected intravitreally. The retinas were harvested 4 h after the BrdU was administered (i.e., day 3) or on days 4, 7, and 21 post detachment. The tissue was fixed, embedded in agarose, and sectioned at 100 microm. The sections were labeled with various combinations of probes, including anti-vimentin and anti-S100 (as markers for Müller cells), anti-BrdU, anti-phosphohistone H3 (to identify mitotic cells), and the isolectin B4 (to identify macrophages and microglia). Images were captured using an Olympus Fluoview 500 confocal microscope. To aid in our understanding of how Müller cell nuclei undergo cell division, two additional procedures were used: 1) electron microscopy of normal cat and rabbit retinas and 2) a new method using 5-fluorouracil and subsequent anti-BrdU labeling to detect all Müller cell nuclei, using confocal imaging., Results: Three days after detachment, anti-vimentin labeled all Müller cells, some of which were also labeled with anti-BrdU. On day 4, many of the anti-BrdU-labeled Müller cell nuclei appeared in columns with one labeled nucleus in the inner nuclear layer and another directly sclerad to it in the outer nuclear layer. By day 7, most anti-BrdU-labeled nuclei were observed in subretinal scars. At 3 weeks, some anti-BrdU-labeled nuclei that remained within the retina did not express vimentin or S100. Anti-phosphohistone H3-labeled (i.e., mitotic) cells, some of which were also labeled with anti-BrdU, were only observed in the outer nuclear layer on day 4, and these nuclei were surrounded by an accumulation of vimentin filaments. Isolectin B4-labeled microglia and macrophages also incorporated BrdU and were observed throughout the retina and in subretinal scars during all times of detachment. Electron microscopy and immunofluorescence labeling of the 5-fluorouracil-injected eyes revealed the presence of a unique structural relationship between Müller cell nuclei and intermediate filament proteins., Conclusions: Following retinal detachment, many Müller cell nuclei initially migrate to the outer retina, undergo mitosis, and eventually reside in subretinal glial scars, suggesting a possible link between the early division of Müller cells and the process of subretinal gliosis. In addition, a subpopulation of anti-BrdU-labeled cells, presumably once Müller cells, appears to stop expressing well accepted Müller cell marker proteins, suggesting a potential dedifferentiation of some of these cells over time. Additionally, Müller cell nuclei may use intermediate filaments as a "track" for migration into the outer retina and later as an important component of cell division by the accumulation of vimentin filaments around the mitotic nuclei.

- Abstract
In the crystal structure of the title salt, C(8)H(12)N(+)·C(2)F(3)O(2) (-), all of the ammonium H atoms serve as donors for hydrogen bonds to carboxyl-ate O atoms, forming an R(4) (3)(10) ring motif based on two cations and two anions. Since both cations and anions act as inter-ion bridging groups, R(10) rings aggregate in a one-dimensional supra-molecular network by sharing the strongest N-H⋯O bond. Edge-sharing motifs lie on the twofold screw axis parallel to [010], and anti-parallel packing of these 2(1)-column structural units results in the crystal structure. This arrangement is one of the most commonly occurring in conglomerates of chiral 1-phenyl-ethyl-amine with achiral monocarboxylic acids, confirming that these ionic salts are particularly robust supra-molecular heterosynthons useful in crystal engineering.
