| 1 | Photoluminescence emissions of Ca_(1-x)WO_(4):xEu^(3+):Bridging between experiment and DFT calculations显示文摘In this work,the impact of the doping process on the photoluminescence emission of CaWO_(4) as a function of the concentration of Eu^(3+) cation(0.01 mol%,0.02 mol%,0.04 mol%,0.06 mol%,0.08 mol%,and 0.10 mol%) is discussed in detail.Ca_(1-x)WO~4:xEu^(3+) samples were successfully synthesized by a simple coprecipitation method followed by microwave irradiation.The blue shift in the absorption edge confirms the quantum confinement effect and the band gap energy covers the range from 3.91 to 4.18 eV,as the amount of Eu^(3+) cations increases.The experimental results are sustained by first-principles calculations,at the density functional theory level,to decipher the geometry and electronic properties,thereby enabling a more accurate and direct comparison between theory and experiment for the Ca_(1-x)WO_(4):xEu^(3+) structure. | Amanda Fernandes Gouveia Marcelo Assis Lara Kelly Ribeiro Aline Estefany Brandao Lima Eduardo de Oliveira Gomes Daniele Souza Yara Gobato Galvao Ieda Lucia Viana Rosa Geraldo Eduardo da Luz Jr Eva Guillamón Elson Longo Juan Andrés Miguel Angel San-Miguel | 2022 | Journal of Rare Earths2022,40,10: | 1 |

| 6 | Abundance and harvest strategy of three species of clam (BivalviaVeneridae) located in new fishing banks in the Gulf of California显示文摘Clams of the family Veneridae in northwest Mexico have traditionally been exploited by small-scale fisheries.Despite their socioeconomic importance for coastal communities in the region,most catch zones are currently in decline due to a lack of harvest control regulations that would impede the depletion of local fishing banks.In Puerto Libertad,in the northern reaches of the Gulf of California,banks of commercially unexploited clam species,including Megapitaria aurantiaca,M.squalida and Dosinia ponderosa,were discovered.The adequate management and exploitation of these banks requires developing basic knowledge regarding the abundance of the species and establishing reference points to determine clear,simple harvest regulations.The goal of this study was to identify population abundance in these banks and ascertain the parameters of the life history of the species found there in order to propose a harvest strategy that will allow the sustainable exploitation of this resource.A total of 288 transects were conducted in the two clam banks to identify species density.Abundance was determined using a geostatistical method.The relative cohort biomass-at-length was estimated to evaluate the effect of different lengths of first capture on the remaining biomass.Based on these data,two harvest control regulations were proposed:a maximum catch(Cmax)of 10%of the total estimated biomass,and a minimum optimal catch size(Lc).The abundance estimates were M.squalida(266,293-381,881 individuals);D.ponderosa(2,779,100-3,455,597);and M.aurantiaca(408,783-447,391).The harvest control regulations proposed are:M.squalida,Cmax=2.98 t and Lc=50.33 mm;D.ponderosa,Cmax=49.67 t and Lc=103.44 mm;and M.aurantiaca,Cmax=15.87 t and Lc=80.85 mm.These results are important as reference information for implementing harvest strategies in clam-fishing banks,and as a contribution to the management and sustainable exploitation of fisheries in the region. | Jorge A.López-Rocha Francisco J.Fernández-Rivera Melo Ernesto Gastélum-Nava Estefani Larios-Castro | 2021 | Aquaculture and Fisheries2021,6,5: | 0 |
| 7 | Chronic urticaria associated with lung adenocarcinoma—a paraneoplastic manifestation:A case report and literature review显示文摘BACKGROUND Urticaria is one of the most common causes of emergency room visits.It is defined as an acute inflammatory dermatosis,characterized by localized degranulation of mast cells,with consequent dermal microvascular and formation of edematous and pruritic plaques called hives.Urticaria affects the skin and tissues of the superficial mucosa.Sometimes it is accompanied by angioedema,which is characterized by deeper edema of the dermis and subcutaneous cellular tissue known as the urticarial-angioedema syndrome.About 15%-25%of the general population has suffered at least one type of urticaria at some point during their lifetime and hyperpermeability estimated at 7.6%-16%and has experienced acute urticaria that is usually self-limited and spontaneously resolves without requiring medical attention.CASE SUMMARY We present the case of a young male patient who was referred to our department with a clinical picture of 4 mo of pruritus associated with hives of variable sizes,irregular borders,with interlesional confluence,that were non-painful,without involvement of the palms and soles of the feet but with a tendency to progression in a generalized manner.He had multiple emergency room visits and poor response to antihistamines and systemic corticosteroids.Imaging studies demonstrated nodules in the lower lingula segment,at the level of the greater fissure and in the anterior contour of the left anterior basal segment associated with parahiliar adenopathies in the absence of findings suggestive of infectious or autoimmune etiology.Segmental lobectomy was performed by thoracoscopy with resection of a lung nodule in the lingula and biopsy of the para-aortic mediastinal ganglion.The histopathological report showed the presence of poorly differentiated invasive adenocarcinoma with a solid morphological and acinar pattern with immunohistochemical description of lung tissue that expresses strong positive and diffuse reaction for thyroid transcription factor 1(TTF-1)with negativity to P40 for a histopathological diagnosis of malignant epithelial neoplasia with expression of infiltrating adenocarcinoma.Spontaneous chronic urticaria is considered possibly secondary to lung adenocarcinoma.CONCLUSION Chronic spontaneous urticaria is considered a paraneoplastic dermatosis with a controversial association in the literature.In the presented case,a young patient presented with chronic refractory urticaria and after an exhaustive clinical work-up was found to have a diagnosis of poorly differentiated lung adenocarcinoma with high expression of TTF-1.According to the Curth criteria,the urticaria presented by the patient is related to the oncological diagnosis.In addition,the high expression of TTF-1 documented in this case could be acting as an autoantigen that would cause chronic spontaneous urticaria.Further research evaluating a causal relationship between the TFF-1 protein and urticaria in lung cancer is needed. | Luisa Fernanda Jiménez Evis Adriana Castellón Juan David Marenco JoséMaria Mejía Camilo Andrés Rojas Franklin Torres Jiménez Linda Coronell Estefanie Osorio-Llanes Evelyn Mendoza-Torres | 2022 | World Journal of Clinical Cases2022,10,21: | 0 |
