Casa Klumb: an issue of preservation and education

Early on the morning of November 11, 2020, we woke to news of the “fire that destroyed the Klumb House.” The somber story that detailed the complete erasure of the emblematic structure, under the custody of the administration of the University of Puerto Rico, at the express wish of the architect Henry Klumb, went viral and broke the Internet. The newspaper columns proliferated with a wide range of views on the issue. Leaving the essential question: Why did this happen

Identification of Genes Responsive to Solar Simulated UV Radiation in Human Monocyte-Derived Dendritic Cells

Ultraviolet (UV) irradiation has profound effects on the skin and the systemic immune system. Several effects of UV radiation on Dendritic cells (DCs) functions have been described. However, gene expression changes induced by UV radiation in DCs have not been addressed before. In this report, we irradiated human monocyte-derived DCs with solar-simulated UVA/UVB and analyzed regulated genes on human whole genome arrays. Results were validated by RT-PCR and further analyzed by Gene Set Enrichment Analysis (GSEA). Solar-simulated UV radiation up-regulated expression of genes involved in cellular stress and inflammation, and down-regulated genes involved in chemotaxis, vesicular transport and RNA processing. Twenty four genes were selected for comparison by RT-PCR with similarly treated human primary keratinocytes and human melanocytes. Several genes involved in the regulation of the immune response were differentially regulated in UVA/UVB irradiated human monocyte-derived DCs, such as protein tyrosine phosphatase, receptor type E (PTPRE), thrombospondin-1 (THBS1), inducible costimulator ligand (ICOSL), galectins, Src-like adapter protein (SLA), IL-10 and CCR7. These results indicate that UV-exposure triggers the regulation of a complex gene repertoire involved in human-DC–mediated immune responses

Benzotriazole derivatives palladium complex: Synthesis, characterization, antifungal and catalytic activity

Two new palladium benzotriazole complexes (7) and (8) was synthetized from [PdCl2(NCCH3)2] (6) and the benzotriazole derivatives 1,3-phenylenebis-((1H-benzotriazol-1-yl)methanone) (3) and 1,3-bis(1H-benzotriazol-1-yl-methyl)benzene (5). Its antifungal and Mizoroki-Heck catalytic preliminar activity was evaluated, finding that the palladium complexes are more effective than the ligands against Aspergillus niger and the turn over number (TON) for the complexes 7 and 8 was 221 and 219, which are under the average for similar complex reported on literature.

Presence of π…π and C-H…π interactions in the new Schiff base 2- {(E)-[(3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)imino]methyl}phenol : experimental and DFT computational studies

A combined theoretical and experimental study on the structure, infrared and UVeVis data of 2-{(E)-[(3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)imino]methyl}phenol (3), is presented. Theoretical geometry optimization and its IR spectrum were carried out using the Density Functional Theory (DFT), while for the theoretical UV-Vis spectrum, the Time-Dependent DFT (TD-DFT) method was used. The supramolecular analysis of the compound evidenced the presence of π… π interactions between the phenol and pyrazole rings and the presence of C-H … π interactions between the methyl group and the phenyl rings which form chains of molecules parallel to the plane (100)

Síntesis Y Caracterización Espectroscópica De Los Productos De Reacción Entre [Ru3(CO)12] Y El Ligando Cloroarilidenrodaninae

Abstract In this article, we report on the synthesis and spectroscopic characterization of two polymeric complexes from [Ru3(CO)12] and 5-(4-chlorobenzylidene)-2-thioxo-1,3-thiazolidin-4-one, Cl-BRd. Spectroscopic evidence shows that the Cl-BRd ligand promotes the breaking of the cluster generating a dimer, and binds to the metal center in different confi gurations. Thus, in product 1, the ligand binds through the nitrogen and oxygen atoms and, in product 2, through the nitrogen atom and the exo-cyclic sulfur. Resumen Este artículo presenta la síntesis y caracterización de los productos de la reacción del agregado (o cluster) [Ru3(CO)12] con el ligando heterocíclico 5-(4-clorobenciliden)-2-tioxo-1, 3-tiazolidin- 4-ona, Cl-BRd. La reacción rindió dos productos, ambos de naturaleza polimérica. Los resultados espectroscópicos muestran que el ligando Cl-BRd promueve el rompimiento del agregado, generando un dímero y se enlaza al centro metálico en diferentes confi guraciones; así, en el producto 1, el ligando utiliza los átomos de nitrógeno y oxígeno y, en el producto 2, usa el átomo de nitrógeno y el azufre exocíclico

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
