Zur Entstehung der griechischen Chorlyrik

2019

Si cerca di dimostrare che la lirica corale è nata nel peloponneso sotto l'influenza di Terpandro, della lirica lesbica e dell'epos. Si confutano itentativi di stabilire un nesso diretto fra la lirica corale e la poesia indoeuropea. Si cerca di mostrare che tutte le forme dattiliche della lirica (in primis i dattilo-epitriti) derivano dall'esametro dattilico epico. Es wird oft behauptet, dass der Ursprung der griechischen Chorlyrik in einer Zeit, die der endgültigen Fixierung des epischen Hexameters vorausgeht, zu verorten sei.1 Da es nun feststeht, dass der homerische Hexameter spätestens um die Mitte des 8. Jh. v. Chr. seine endgültige Form erhielt,2 müsste man besagter Theorie zu Folge z…

Solution nuclear magnetic resonance spectroscopy on a nanostructured diamond chip

2017

We demonstrate nuclear magnetic resonance (NMR) spectroscopy of picoliter-volume solutions with a nanostructured diamond chip. Using optical interferometric lithography, diamond surfaces were nanostructured with dense, high-aspect-ratio nanogratings, enhancing the surface area by more than a factor of 15 over mm^2 regions of the chip. The nanograting sidewalls were doped with nitrogen-vacancy (NV) centers so that more than 10 million NV centers in a (25 micrometer)^2 laser spot are located close enough to the diamond surface (5 nm) to detect the NMR spectrum of 1 pL of fluid lying within adjacent nanograting grooves. The platform was used to perform 1H and 19F NMR spectroscopy at room tempe…

Circulating miR-22, miR-24 and miR-34a as Novel Predictive Biomarkers to Pemetrexed-Based Chemotherapy in Advanced Non-Small Cell Lung Cancer

2013

Pemetrexed has been widely used in patients with advanced non-small cell lung cancer (NSCLC). The clinical relevance of polymorphisms of folate pathway genes for pemetrexed metabolism have not been fully elucidated yet. The aim of this study was to evaluate the expression levels of circulating miR-22, miR-24, and miR-34a, possibly involved in folate pathway, in NSCLC patients treated with pemetrexed compared with healthy controls and to investigate their impact on patient clinical outcomes. A total of 22 consecutive patients with advanced NSCLC, treated with pemetrexed-based chemotherapy and 27 age and sex matched healthy controls were included in this preliminary analysis. miR-22, miR-24, …

Diffuse malignant biphasic peritoneal mesothelioma with cystic areas

2016

We report a case of peritoneal biphasic mesothelioma with cystic areas in a patient with professional exposure to asbestos. It showed focal epithelial glandular and papillary proliferations, also presenting fluid filled cysts, whose wall consisted of a proliferation of spindle cells. Atypia and mitoses were very scanty. EMA, vimentin, CK5/6, D2-40, calretinin and P53 were positive and desmin was negative in both epithelial and spindle areas, including the ones surrounding the cystic spaces. These findings gave an essential aid in the differential diagnosis with a benign cystic mesothelioma and with a cystic epithelial mesothelioma with secondary pseudosarcomatous myofibroblastic proliferati…

Cost-effectiveness analysis of pemetrexed versus docetaxel in the second-line treatment of non-small cell lung cancer in Spain: results for the non-s…

2010

Abstract Background The objective of this study was to conduct a cost-effectiveness evaluation of pemetrexed compared to docetaxel in the treatment of advanced or metastatic non-small cell lung cancer (NSCLC) for patients with predominantly non-squamous histology in the Spanish healthcare setting. Methods A Markov model was designed consisting of stable, responsive, progressive disease and death states. Patients could also experience adverse events as long as they received chemotherapy. Clinical inputs were based on an analysis of a phase III clinical trial that identified a statistically significant improvement in overall survival for non-squamous patients treated with pemetrexed compared …

Nanoemulsions for synthesis of biomedical nanocarriers

2021

Nanoemulsions are kinetically stabilized emulsions with droplet sizes in the nanometer scale. These nanodroplets are able to confine spaces in which reactions of polymerization or precipitation can take place, leading to the formation of particles and capsules that can act as nanocarriers for biomedical applications. This review discusses the different possibilities of using nanoemulsions for preparing biomedical nanocarriers. According to the chemical nature, nanocarriers prepared in nanoemulsions are classified in polymeric, inorganic, or hybrid. The main synthetic strategies for each type are revised, including miniemulsion polymerization, nanoemulsion-solvent evaporation, spontaneous em…

Non-destructive technique to detect local buried defects in metal sample by scanning microwave microscopy

2012

International audience; Based on the skin effect, our recent developments using scanning microwave microscopy lead to propose a non-destructive method to detect located buried defect in metal samples like stainless steel. A 3D tomography is possible by taking advantage of microwave measurement, using a vector network analyzer in bandwidth frequencies, and the nanometer resolution positioning capabilities with atomic force microscopy. At each used frequency, an incident electromagnetic wave is sent to the sample and the reflected wave gives information on a specific depth layer in the material. With diagnostic tools of nanotechnologies (SEM. AFM, etc.), different stainless steel samples (fro…

Synthesis and Characterization of Nanostructured Cobalt Hexacyanoferrate

2010

Cobalt hexacyanoferrate (CoHCF) nanoparticles have been synthesized by mixing aqueous solutions of K3Fe(CN)6 and CoCl2 under vigorous stirring at different temperatures and following two different procedures, drop-by-drop or immediate mixing. The resulting CoHCF nanoparticles, with dimensions of several tens of nanometers, were characterized using TEM, SEM-EDX, IR, and XRD. Their electrochemical behavior was investigated in comparison with the CoHCF powder bulk compound. The CoHCF nanoparticles exhibit an electrochemically driven conversion to the bulk one that has been investigated by a chemometric approach in order to establish the best synthetic parameters. The rate and the degree of con…
