description: ABSTRACTUnlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles. This protein, H2A.V, combines the features of the conserved variants H2A.Z and H2A.X in transcriptional control/heterochromatin assembly and DNA damage response, respectively. Here we show that mutations in the gene encoding H2A.V affect chromatin compaction and perturb chromosome segregation in Drosophila mitotic cells. A microtubule (MT) regrowth assay after cold exposure revealed that loss of H2A.V impairs the formation of kinetochore-driven (k) fibers, which can account for defects in chromosome segregation. All defects are rescued by a transgene encoding H2A.V that lacks the H2A.x function in the DNA damage response, suggesting that the H2A.Z (but not H2A.X) functionality of H2A.V is required for chromosome segregation. We also found that loss of H2A.V weakens HP1 localization, specifically at the pericentric heterochromatin of metaphase chromosomes. Interestingly, loss of HP1 yielded not only telomeric fusions but also mitotic defects similar to those seen in H2A.V null mutants, suggesting a role for HP1 in chromosome segregation. We also show that H2A.V precipitates HP1 from larval brain extracts indicating that both proteins are part of the same complex. Moreover, we found that the overexpression of HP1 rescues chromosome missegregation and defects in the kinetochore-driven k-fiber regrowth of H2A.V mutants indicating that both phenotypes are influenced by unbalanced levels of HP1. Collectively, our results suggest that H2A.V and HP1 work in concert to ensure kinetochore-driven MT growth.

description: Before a cell enters mitosis, the Golgi apparatus undergoes extensive fragmentation. This is required for the correct partitioning of the Golgi apparatus into daughter cells, and inhibition of this process leads to cell cycle arrest in G2 phase. AMP-activated protein kinase (AMPK) plays critical roles in regulating growth and reprogramming metabolism. Recent studies have suggested that AMPK promotes mitotic progression and Golgi disassembly, and that this seems independent of the cellular energy status. However, the molecular mechanism underlying these events is not well understood. Here, we show that both treatment with compound C and depletion of AMPKα2 (but not AMPKα1) delays the G2/M transition in synchronized HeLa cells, as evidenced by flow cytometry and mitotic index analysis. Furthermore, knockdown of AMPKα2 specifically delays further fragmentation of isolated Golgi stacks. Interestingly, pAMPKαThr172 signals transiently appear in the perinuclear region of late G2/early prophase cells, partially co-localizing with the Golgi matrix protein, GM-130. These Golgi pAMPKαThr172 signals were also specifically abolished by AMPKα2 knockdown, indicating specific spatio-temporal activation of AMPKα2 at Golgi complex during late G2/early prophases. We also found that the specific CaMKKβ inhibitor, STO-609, reduces the pAMPKα Thr172 signals in the perinuclear region of G2 phase cells and delays mitotic Golgi fragmentation. Taken together, these data suggest that AMPKα2 is the major catalytic subunit of AMPKα which regulates Golgi fragmentation and G2/M transition, and that the CaMKKβ activates AMPKα2 during late G2 phase.

description: Hoxa5 is preferentially expressed in hematopoietic stem cells (HSCs) and multipotent progenitor cells (MPP), and is more highly expressed in expanding HSCs. To date, little is known regarding the role of Hoxa5 in HSCs and downstream progenitor cells in vivo. In this study, we show that increased expression of Hoxa5 in hematopoietic stem cells leads to aberrant erythropoiesis in vivo. Hoxa5 differentially modifies the cell cycle of HSCs and lineage committed progenitor cells, depending on the cellular context. Hoxa5 drives HSCs, but not MPPs, through the cell cycle and arrests erythroid progenitor cells in G0 phase. Although the HSC pool shrinks after overexpression of Hoxa5, HSCs sustain the abilities of self-renewal and multipotency. In vivo, Hoxa5 has two effects on erythropoiesis: it causes a predominance of mature erythroid lineage cells and the partial apoptosis of erythroid progenitors. RNA-seq indicates that multiple biological processes, including erythrocyte homeostasis, cell metabolism, and apoptosis, are modified by Hoxa5. The results of this study indicate that Hoxa5 is a key regulator of the HSC cell cycle, and the inappropriate expression of Hoxa5 in lineage-committed progenitor cells leads to aberrant erythropoiesis.

description: In this paper, we introduce surface modified gold nanoparticles with mesogenic thiol ligands in liquid crystal, for expansion of the temperature range of blue phases (BPs). We have used polarized optical microscope and UV-vis spectrophotometer to identify the thermal stabilization of BPs. The BPs range of nanoparticles doped liquid crystal is significantly dependent upon the addition amount of gold nanoparticles, and the molar ratios of attached ligands [4′-(10-mercaptodecyloxy)biphenyl-4-carbonitrile and dodecanethiol]. This study could provide a new and facile strategy to stabilize BPs, from the aspect of the surface modification of nanoparticles.

description: Two new supramolecular compounds, 2C6H9N2+. C8H4O4−.2H2O /(4AMPIP) (1) and C6H9N2+.C8H5O4−/(5AMPHIP) (2), were synthesized and characterized by IR spectra, 1HNMR, 13CNMR, and single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system, space group Cc, with a = 7.8914(3), b = 38.4226(16), c = 7.3354(3) Å, β = 107.9460(10)˚, V = 2115.94(15) Å3, Dc = 1.314 g/cm3, F(000) = 888, μ = 0.10 mm−1, Z = 4, the final R = 0.0298, and wR = 0.0835 for 3135 observed reflections with I > 2σ(I); and compound 2 crystallizes in the monoclinic system, space group P21/c, with a = 9.0126(2), b = 12.2055(3), c = 12.3170(2) Å, β = 104.2160(10)°, V = 1313.42(5) Å3, Dc = 1.387 g/cm3, F(000) = 576, μ = 0.103 mm−1, Z = 4, the final R = 0.0454, and wR = 0.1130 for 2799 observed reflections with I > 2σ(I). The 2-amino-4-methylpyridinium (4AMP) and 2-amino-5-methylpyridinium (5AMP) cations are protonated at one of the pyridinium N atoms. In both compounds, the isophthalate anion interacts with protonated cations through a pair of N‒HċċċO hydrogen bonds to form a cyclic hydrogen-bonded motif with graph-set notation (R22(8)). In the crystal structure of 1, the ion pairs (whether cation/anion) are linked by water molecules through O‒HċċċO, N‒HċċċO, and weak C‒HċċċO hydrogen bonds, forming a three-dimensional network. In the crystal structure of 2, there are chains and layer made up of the O‒HċċċO, N‒HċċċO, and C‒HċċċO hydrogen bonds, forming a two-dimensional network.

Subjects: Clinical Psychology

description:     Despite the amount of evidence supporting trauma-informed care and its effectiveness in providing a holistic approach to patient care, based on the research, very few organizations implement trauma-informed care effectively or at all. Understanding the knowledge, attitudes, practice, and perceived barriers to trauma-informed care among multidisciplinary health professionals is essential to inform the execution efforts of trauma-informed care. In addition, exploring trauma-informed care within facilities that serve at-risk populations, such as Federally Qualified Health Centers (FQHC), is essential to reach those in need. This study examined the effectiveness of a trauma-informed webinar-based training on the knowledge and attitudes of trauma-informed care for healthcare professionals working in the FQHC setting from baseline to post-intervention. Building on existing research on trauma-informed care, this study explored if the knowledge, attitude, and practice factors were interrelated. In addition, this study investigated if the type of healthcare professional, setting of the FQHC, and/or level of previous trauma-informed care training impacted knowledge, attitude, and perceived barriers towards trauma-informed care at baseline. To assess the relationship between variables, Bivariate correlations were used. To analyze the change of knowledge and attitude from pre-intervention to post-intervention, a repeated measures t-test was used. Additionally, a Mann-Whitney U and Kruskal Wallis test was used to determine if specific professional demographics predicted the levels of knowledge, attitude, and perceived barriers toward trauma-informed care at baseline. Overall, this study found that there is a significant correlation between knowledge, attitude, and practice, indicating a cyclical impact. Additionally, results indicate differences in perceived barriers and attitude between medical and mental health professionals, whereby medical professionals encountered more barriers, but mental health professional indicated stronger attitudes. Further, these findings are in line with other results indicating that the intervention was successful in improving attitudes, as was participants previous TIC training. However, contradictory to the literature, there was no difference in knowledge between the two groups and the intervention nor previous trainings improved knowledge. Lastly, area of residence was not found to have any impact on knowledge or attitudes. These findings reinforce the current body of literature and impose needed effort in improving the manner in which trauma-informed care is executed.

description: La reciente alianza interinstitucional de la Universidad del Rosario con la Orden Hospitalaria de San Juan de Dios y la Caja de Compensación Familiar (Compensar), como red hospital- universitario representa una gran oportunidad para consolidar la capacidad de generar conocimiento sobre los principales temas de salud que el país confronta, y de aplicarlo a mejorar los servicios de salud en el Distrito Capital y en Colombia. Recientes estudios adelantados por la Facultad de Economía de la Universidad del Rosario1 muestran claramente la forma como en América Latina ha surgido una importante comunidad de investigación en temas clínicos (investigación clínica), convirtiendo al hospital tradicional en una organización del conocimiento. A fin de que los hospitales tengan la capacidad de responder a los desafíos que confrontan en la sociedad del siglo XXI, deben conocer y desarrollar su capacidad para convertirse en hospitales de conocimiento, en particular aquel que se deriva de la práctica e investigación clínica. Ello pasa por dimensionar la capacidad de las organizaciones y los individuos para conducir investigación, usar sus resultados y transferirlos de manera eficiente, efectiva y sostenible.Alineadas con esta realidad, las facultades de Medicina y Rehabilitación y Desarrollo Humano de la Universidad del Rosario, que hoy conforman la nueva Escuela de Medicina y Ciencias de la Salud, a través de los grupos de investigación en Rehabilitación e Integración Social de la Persona con Discapacidad y de Investigación Clínica, participaron de la convocatoria 2008 del Fondo de Investigación de la Universidad del Rosario, con el proyecto denominado “Capacidad para la Investigación Clínica en la Red Hospitalaria Méderi”, cuyo objetivo es caracterizar la capacidad para la investigación clínica en la red local de hospitales de Méderi, y definir estrategias de desarrollo y fortalecimiento de dicha capacidad, con miras a convertirse en un hospital de conocimiento. Con este fin, se planteó realizar un análisis diagnóstico de la capacidad existente para hacer investigación clínica en la red hospitalaria Méderi, y proyectar dicha capacidad con el fin de lograr sus objetivos. Para este análisis se está desarrollando una “estructura analítica mixta” que permitirá caracterizar la estructura y organización de la red hospitalaria.

description: It is currently accepted that noise is one of the most important annoyance factors in open-space offices. However, noise levels measured in open spaces of the tertiary sector rarely exceed 65 dB(A). It, therefore, appears necessary to develop a tool that can be used to assess the noise environment of these offices and identify the parameters to be taken into consideration when assessing the noise annoyance. This article presents a questionnaire to be filled by people working in such environment, and a case study in different open plan offices. The majority of the 237 respondents consider that the ambient noise level in their environment is high and that intelligible conversations between their colleagues represent the main source of noise annoyance. This annoyance was significantly correlated with their evaluation of sound intensity, which could not be represented by A-weighted level measurements.

description: Healthcare systems need to be redesigned to provide care that is safe, effective and efficient, and meets the multiple needs of patients. This systematic review examines how human factors and ergonomics (HFE) is applied to redesign healthcare work systems and processes and improve quality and safety of care. We identified 12 projects representing 23 studies and addressing different physical, cognitive and organisational HFE issues in a variety of healthcare systems and care settings. Some evidence exists for the effectiveness of HFE-based healthcare system redesign in improving process and outcome measures of quality and safety of care. We assessed risk of bias in 16 studies reporting the impact of HFE-based healthcare system redesign and found varying quality across studies. Future research should further assess the impact of HFE on quality and safety of care, and clearly define the mechanisms by which HFE-based system redesign can improve quality and safety of care.
