Feynman diagrams as a weight system: four-loop test of a four-term relation
1996
At four loops there first occurs a test of the four-term relation derived by the second author in the course of investigating whether counterterms from subdivergence-free diagrams form a weight system. This test relates counterterms in a four-dimensional field theory with Yukawa and $\phi^4$ interactions, where no such relation was previously suspected. Using integration by parts, we reduce each counterterm to massless two-loop two-point integrals. The four-term relation is verified, with $ = 0 - 3\zeta_3 + 6\zeta_3 - 3\zeta_3 = 0$, demonstrating non-trivial cancellation of the trefoil knot and thus supporting the emerging connection between knots and counterterms, via transcendental number…
Insulin-like growth factor 1 differentially regulates estrogen receptor-dependent transcription at estrogen response element and AP-1 sites in breast…
2007
Cross-talk between insulin-like growth factor 1 (IGF-1) and estrogen receptor alpha (ER) regulates gene expression in breast cancer cells, but the underlying mechanisms remain unclear. Here, we studied how 17-beta-estradiol (E2) and IGF-1 affect ER transcriptional machinery in MCF-7 cells. E2 treatment stimulated ER loading on the estrogen response element (ERE) in the pS2 promoter and on the AP-1 motif in the cyclin D1 promoter. On ERE, similar amounts of liganded ER were found at 1-24-h time points, whereas on AP-1, ER binding fluctuated over time. At 1 h, liganded ER was recruited to ERE together with histone acetyltransferases SRC-1 and p300, ubiquitin ligase E6-AP, histone methyltransf…
F.A. Wolf, la scienza dell’antichità e noi: come possiamo uscire dal XIX secolo?
2011
International audience; Wolf’s historical-philological Altertumswissenschaft was an academic knowlegde helpful to the State because of its space and time limits, its methods and rhetoric, his idea of the Ancients as a mirror of modern ideals. The present crisis of this paradigm can be related to State’s decline and to modern globalisation, then to the development of fragmented research fields. This development isolated scholars from society and strengthened the problem of the meaning of studies. We can find a possible meaning of these studies for example: 1) by writing the history of the non-violent fights, 2) by trying the counterfactual history or the countertextual writing, examining the…

Numerical Taxonomy of Pseudomonads Isolated from Water, Sediment and Eels
1992
Summary A numerical taxonomic study was performed on 129 pseudomonad isolates from aquatic environments. 67 out of 98 field strains were isolated from water and sediment samples from Albufera lake, a hypereutrophic lake near Valencia, and 31 strains came from an eel hatchery. 10 clusters were formed at 84% similarity level when the Sokal-Michener similarity coefficient was used. Five clusters were designated as Pseudomonas putida (16 strains), P. fluorescens biotype I (9 strains), P. pseudoalcaligenes (11 strains), P. stutzen (4 strains) and Shewanella putrefaciens (3 strains). A subcluster of 7 strains (out of 15) was ascribed to the species Xanthomonas maltophilia , while the other strain…

Halitosis: new insight into a millennial old problem.
2011
The problem of halitosis has been reported since ancienttimes. References have been found in papyrus manuscriptsdating back to 1550 BC. Hippocrates advised that any girlshould have pleasant breath, making sure always to washher mouth with wine, anise and dill seeds [1].More than50 years ago, Blackburn [2] investigated halitosis in a case-series of 73 patients affected by leukemia. He found apeculiar odor of the breath resembling that of a freshlyopened corpse. This characteristic smell is not associatedwith clinical involvement of the gum, mouth, or upperrespiratory or alimentary tract. He associated this particularsmell with the hematologic disease. Nearly 15 years ago,the role of cadaveri…
