Tertiary cytoreduction in the setting of recurrent ovarian cancer (Review)
2013
Ovarian cancer is the most lethal gynecological malignancy, with aggressive surgical debulking and adjuvant chemotherapy as the main treatment modalities. Optimal debulking during the primary surgery is significantly correlated with prolonged survival. As surgical techniques and chemotherapeutic agents improve, more patients with prolonged survival may face secondary and tertiary recurrences. The role of surgical debulking in secondary cytoreduction (SC) is not clearly defined and is based on retrospective series. The treatment of patients with primary or secondary recurrences generally consists of second-line chemotherapy, but may be performed on medically fit patients in certain circumsta…

Environmental RNA outperforms eDNA metabarcoding in assessing impact of marine pollution: A chromium-spiked mesocosm test
2022
Environmental (e)DNA metabarcoding holds great promise for biomonitoring and ecotoxicological applications. However, few studies have compared the performance of eDNA versus eRNA metabarcoding in assessing organismal response to marine pollution, in experimental conditions. Here, we performed a chromium (Cr)-spiked mesocosm experimental test on benthic foraminiferal community to investigate the effects on species diversity by analysing both eDNA and eRNA metabarcoding data across different Cr concentrations in the sediment. Foraminiferal diversity in the eRNA data showed a significant negative correlation with the Cr concentration in the sediment, while a positive response was observed in t…
Frantumazione e armonia:dinamiche della "diluizione" urbana nella Piana dei Colli di Palermo
2009
La piana dei Colli di Palermo è un territorio ordito da molteplici valori storici e culturali che nel tempo hanno intessuto relazioni espressive con la natura, rispecchiando forme differenti di organizzazione fisica e sociale, ora degradate e annegate nello sprawl dilagante. Residui di giardini, improntati all’utilità e dediti alla bellezza, sono diluiti in una dimensione urbana che frantuma equilibri ecologici e sociali. Piani e programmi, in evidente conflitto d’interessi pubblici, perseguendo avversi principi, disegnano difformi strategie di rigenerazione, mostrando la necessità d’interazioni creative e armoniose con gli abitanti, al fine di ristabilire etiche connessioni con la natura e…
A actual crise planetária. Uma dimensão esquecida na educação em ciência
2004
Afinalidade da presente investigação foi analisar qual o possível contributo da Educação em Ciência na clarificação e compreensão pública dos problemas e desafios relacionados com o futuro do nosso planeta. Iniciámos o trabalho procurando o contributo de diferentes estudos elaborados numa perspectiva holística, tendo como objectivo principal elaborar uma visão global do estado do planeta Terra e estudar as possíveis causas e soluções para os problemas identificados. Posteriormente analisámos as percepções de professores de ciências, 327 'em serviço' e 521 'em formação' de Espanha, Portugal e América Latina. Analisámos, ainda, o conteúdo de 127 manuais escolares referentes ao ensino secundár…
Sarcoma Botryoides: Optimal Therapeutic Management and Prognosis of an Unfavorable Malignant Neoplasm of Female Children
2023
Embryonal rhabdomyosarcoma (ERMS) is a rare malignancy and occurs primarily in the first two decades of life. Botryoid rhabdomyosarcoma is an aggressive subtype of ERMS that often manifests in the genital tract of female infants and children. Due to its rarity, the optimal treatment approach has been a matter of debate. We conducted a search in the PubMed database and supplemented it with a manual search to retrieve additional papers eligible for inclusion. We retrieved 13 case reports and case series, from which we summarized that the current trend is to approach each patient with a personalized treatment plan. This consists of a combination of local debulking surgery and adjuvant or neoad…
Calcification is not the Achilles' heel of cold-water corals in an acidifying ocean
2015
Ocean acidification is thought to be a major threat to coral reefs: laboratory evidence and CO2 seep research has shown adverse effects on many coral species, although a few are resilient. There are concerns that cold-water corals are even more vulnerable as they live in areas where aragonite saturation (?ara) is lower than in the tropics and is falling rapidly due to CO2 emissions. Here, we provide laboratory evidence that net (gross calcification minus dissolution) and gross calcification rates of three common cold-water corals, Caryophyllia smithii, Dendrophyllia cornigera, and Desmophyllum dianthus, are not affected by pCO2 levels expected for 2100 (pCO2 1058 ?atm, ?ara 1.29), and nor a…
Prospective Comparison of Loop Excision under Colposcopic Guidance versus Vitom Guidance.
2012
Background: Aim of the study was to compare the quality of loop excision using a colposcope with results using the VITOM system. Results compared included cervical volume removed, intra- and postoperative complications, and positive resection margins. Methods: A total of 200 patients with histologically confirmed high-grade cervical premalignant lesions, persistent atypical cytological results and/or suspicious colposcopic findings, and cytological and histological discrepancies were included in the study. In transformation zone type 1 (T1) only a superficial cone biopsy was done, in zones type 2 and 3 (T2 and T3) a superficial outside cone biopsy or a deeper inside cone biopsy were done re…
