Anti-Social Realism

Work included in a group exhibition at Charlie Smith Gallery, London curated by Juan Bolivar and John Stark. Exhibting artists include: Juan Bolivar, Dan Coombs, Graham Crowley, Karen David, Nathan Eastwood, Geraint Evans, John Greenwood, Sigrid Holmwood, Kate Lyddon, Maharishi x Rebecca & Mike, John Salt, John Stark. The term 'Anti-Social Realism', which acts as this exhibitions title, is not one that is commonly understood. It is intended to pose questions such as: is 'revolutionary' art a viable possibility today? What does it mean to be (anti) social in an increasingly interconnected but physically separated society? Can we, through archaic practices such as painting and sculpture, engage with notions of 'social realism’ now presented on a daily basis through the new silver-screen veneer of the digital age? In response, this exhibition attempts to pose pictorial possibilities and create tensions through the selected artworks, tackling notions of contemporary realism and in turn offering us a distant echo of a political reality. The wry misnomer of the exhibition title slips between many interwoven threads, simultaneously conjuring up images of 'anti-social behaviour orders' (ASBO), anarchist riots, or the solitary artist locked away from the world attempting to connect on a higher level. In this light, the exhibiting artists are presented as 'social mystics' and it could be said that their work operates by a means of turning inwards to create social radiation

To make Pd-NPs, resting cells are challenged with Pd(II) ions (uptake), followed by addition of electron donor to promote bioreduction of cell-bound Pd(II) to Pd(0) (bio-Pd). Application of radiofrequency (RF) radiation to prepared 5 wt% bio-Pd catalyst (60 W power, 60 min) increased the hydrogenation rate by 70% with no adverse impact on selectivity to cis-2-pentene. Such treatment of a 5 wt% Pd/carbon commercial catalyst did not affect the conversion rate but reduced the selectivity. Lower-dose RF radiation (2-8 W power, 20 min) was applied to the bacteria at various stages before and during synthesis of the bio-scaffolded Pd-NPs. The reaction rate (mu mol 2-pentyne converted s(-1)) was increased by similar to threefold by treatment during bacterial catalyst synthesis. Application of RF radiation (2 or 4 W power) to resting cells prior to Pd(II) exposure affected the catalyst made subsequently, increasing the reaction rate by 50% as compared to untreated cells, while nearly doubling selectivity for cis 2-pentene. The results are discussed with respect to published and related work which shows altered dispersion of the Pd-NPs made following or during RF exposure.UK Research & Innovation (UKRI) Engineering & Physical Sciences Research Council (EPSRC) EP/I007806/1 EP/D05768X/1UK Research & Innovation (UKRI) Biotechnology and Biological Sciences Research Council (BBSRC) BB/C516128/1UK Research & Innovation (UKRI)Natural Environment Research Council (NERC) NE/L014076/1Royal Society of London European CommissionSpanish Government Sistema Nacional de Garantia Juvenil grant PEJ-2014-P-0039

Chromosomal and SRY gene findings by FISH in patients with disorders of sexual development

Objetivo: Los trastornos del desarrollo sexual son un grupo de enfermedades congénitas que afectan la formación normal de los genitales. Dentro los mecanismos fisiopatológicos descritos existen factores genéticos causados por alteraciones cromosómicas o en los genes determinantes en la diferenciación sexual. En este trabajo se analizaron alteraciones cromosómicas y en el gen SRY como posible causa del trastorno. Se realizó cariotipo con bandas G o R y FISH para SRY en linfocitos, tejido gonadal y tejido escrotal. Materiales y métodos: La información clínica de los sujetos de investigación se obtuvo de los informes de los médicos tratantes. En 9 (73%) casos el sexo asignado fue masculino y en 3 (27%) casos fue femenino. 8 de los casos (66%) tuvieron cariotipo 46,XY; 2 casos (17%) 46,XX y en 2 casos (17%) se reportaron mosaicos con presencia de idic(Y). Un solo caso de tejido gonadal mostró mosaicismo debido a la presencia de una línea celular tetraploide. El diagnóstico clínico más frecuente fue de genitales ambiguos en 8 casos (67%). Seguido de hipospadias en 5 casos (41,7%). Conclusiones: Los resultados muestran la importancia de aplicar diferentes pruebas citogenéticas en el diagnóstico y la necesidad del seguimiento de los pacientes por un equipo transdisciplinario para abordar estas condiciones clínicas.Q4Pacientes diagnosticados con trastornos del desarrollo sexualObjective: Disorders of sexual development are a group of congenital diseases that affect the normal formation of genital structures. Within the pathophysiologic mechanisms described, there are genetic factors caused by chromosomal or sex-determining gene alterations. Therefore, chromosomal analysis is an essential priority in the diagnostic approach. Alterations in the chromosomes and the SRY gene as a cause of disorder of sexual development was analyzed herein. Material and methods: G or R-banding karyotype and FISH analyses for the SRY gene were performed in lymphocytes, gonadal tissue, and scrotal tissue in twelve cases, three cases, and one case, respectively. The clinical information was obtained from the patients’ medical reports. Results: In 9 (73%) cases, the assigned sex was male, and in 3 (27%) cases, it was female. Karyotype 46,XY was found in 8 (66%) cases, 46,XX in 2 (17%) cases, and mosaic karyotype in 2 (17%) cases with idic(Y). A single case of gonadal tissue showed mosaicism due to the presence of a tetraploid cell line. The most common clinical diagnosis was abnormal genital differentiation in 8 (67%) cases, followed by hypospadias in 5 (41.7%) cases. Conclusions: The results show the importance of applying different cytogenetic tests in making the diagnosis, and the need for a multidisciplinary team to address the disorder.https://orcid.org/0000-0001-7501-7307https://orcid.org/0000-0002-0729-6866https://orcid.org/0000-0002-1421-3619https://orcid.org/0000-0001-6336-5347https://orcid.org/0000-0001-8528-4433https://orcid.org/0000-0002-2231-4321https://orcid.org/0000-0002-7856-7213https://orcid.org/0000-0003-2241-7854https://orcid.org/0000-0002-9675-5963https://orcid.org/0000-0001-5685-8354https://orcid.org/0000-0002-0826-6191Revista Internacional - IndexadaCN

The need for medical or surgical treatment depends on the severity of the lower urinary tract symptoms. The gold standard for surgical treatment is bipolar transure-thral resection of the prostate (b-turp). Objective: To evaluate the different surgical techniques, comparing their effi-cacy and safety in the treatment of benign prostatic hyperplasia.Methods: A narrative review of the literature was carried out through a search of five databases: PubMed, Embase, Lilacs, Science Direct, and GreyNet. Me-ta-analyses, systematic reviews, and randomized clinical trials published from 2006 to 2016 were evaluated to determine the efficacy and safety of the surgi-cal techniques for the treatment of benign prostatic hyperplasia.Results: A total of 2505 articles were selected by title and abstract and the complete texts of 94 of those articles were reviewed. The different surgical techniques encountered were monopolar turp, bipolar turp, open prostatec-tomy, plasma vaporization, laser techniques, and minimally invasive ablation techniques. The majority of the articles compared bipolar turp (the gold stan-dard) vs other surgical methods, focusing on clinical outcomes based on the ipss, qmax, pvr, and qoL instruments. The results were similar among all the techniques.Conclusions:Bipolar turp is the most widely practiced technique for benign prostatic hyperplasia management and has good results, compared with mono-polar turp. Results are similar between the bipolar turp, holep, thulep, Green-light laser, and tumt modalities. The choice of surgical technique is dependent on the expertise of the surgeon and the characteristics of each patient. The re-sults of the present review are heterogeneous, making further study necessary.https://orcid.org/0000-0002-5895-3029https://orcid.org/0000-0001-5685-8354https://orcid.org/0000-0003-4787-1228https://orcid.org/0000-0002-8547-9182https://orcid.org/0000-0003-2633-6971Revista Internacional - IndexadaCN

Bio-Based Fire Retardant for Coco Lumber using Aloe barbadensis miller (Aloe Vera), Mangifera indica (Mango), or Persea americana (Avocado) and Boron Additives

Accidental fires are prevalent in low-income communities and one of the solutions to decrease fire risk is to apply fire retardants on combustible materials. While extensive research was available in creating fire retardants with inorganic chemicals, further studies are needed for bio-based fire retardants. The development of bio-based fire retardants involves testing organic matter for the presence of fire-retardant compounds such as nitrogen, phosphorus, and polyphenols. This study sought to determine the effectiveness of the peels of Aloe barbadensis miller (aloe vera), Mangifera indica (mangoes), and Persea americana (avocados) in creating bio-based fire retardants for coco lumber. Maceration was used to get the fruit and plant extracts. Boric acid and borax were also added as additives to boost fire retarding properties. The burning behavior of the lumber was observed in a modified horizontal flammability test and a modified flame spread test and measured in terms of mass loss, smoke density, char yield, and charring rate. The results revealed that among the fruits, the mango-based fire-retardant inhibited mass loss the most (M = 0.006, SD = 0.003), while the avocado-based fire-retardant inhibited smoke the most (M = 0.036, SD = 0.016). No significant difference was found among the groups as determined by One-way ANOVA and MANOVA (p \u3e 0.05). An indirect relationship was found between smoke density and char yield, which may be examined to improve the smoke suppressing ability of commercial fire retardants. Future studies may also refine the plant extracts and use standard flammability tests
