Risposta dei bioindicatori della qualità del suolo alla diversa fertilizzazione di un aranceto nell’ Italia Meridionale

2013

Lo scopo della ricerca è stato quello di valutare i cambiamenti indotti dalle diverse tipologie di fertilizzazione sui parametri chimici e biologici di un suolo. Il suolo dell’agro di Lentini (SR, Sicilia), coltivato ad arancio da oltre 50 anni, a partire dal 1995 secondo il metodo biologico , omogeneo per portinnesto e cultivar, è stato addizionato con 4 diversi tipi di fertilizzanti (pollina, minerale, compost da pastazzo e letame). Quattro profili di suolo, ciascuno per tipo di fertilizzazione, sono stati campionati e studiati secondo la sequenza degli orizzonti genetici. In totale 18 campioni orizzonte-specifici di suolo sono stati prelevati e sottoposti ad analisi per valutare il conte…

Ogni impresa umana di educazione è sempre un tentativo, riuscito o meno, di portare risposta ad un fondamentale bisogno di riconoscimento. Questo è, secondo un primo significato che possiamo chiamare affettivo, bisogno, per essere, di essere riconosciuti nell'essere; mentre, secondo un altro significato che è etico o culturale, bisogno di essere aiutati ad entrare in un universo simbolico, innanzitutto quello cui si è originariamente consegnati. La crescita educativa è un'opera di personalizzazione, in senso storico ed esistenziale, della consegna e dell'appello che essa porta

Functionally active complement proteins C6 and C7 detected in C6- and C7-deficient individuals

1991

SUMMARYTwo sensitive sandwich ELISAs based on monoclonal antibodies directed to native C6 and C7 allowed the detection and quantitation of these complement proteins in 20 out of 37 serum samples from individuals who had previously been classified as deficient in these proteins as assessed by immunochemical and/or functional assays. Furthermore, serum from four C6-deficient and one combined C6-/C7-deficient individual showed an increase in the terminal complement complex (TCC) and a decrease in native C6 and C7 after complement activation as assayed by specific ELISAs. Despite their (incomplete) deficiencies, these individuals therefore possess functionally active terminal complement protein…

Platelet-endothelial interaction in tumor angiogenesis and microcirculation

2003

Activated platelets release angiogenic growth factors and have therefore been proposed to contribute to tumor angiogenesis within a potentially prothrombotic tumor microcirculation. The aim of the study was to investigate interactions of platelets with the angiogenic microvascular endothelium of highly vascularized solid tumors during growth and in response to endothelial stimulation in comparison with normal subcutaneous tissue. Experiments were performed in the dorsal skinfold chamber preparation of C57BL/6J mice bearing the Lewis lung carcinoma (LLC-1) or methylcholanthrene-induced fibrosarcoma (BFS-1). Fluorescently labeled rolling and adherent platelets, red blood cell velocity, and ve…

Inhibition of inflammatory responses by epitaondiol and other marine natural products

1995

The marine metabolites pacifenol, stypotriol triacetate and epitaondiol were tested for their effects on a number of inflammatory responses. Epitaondiol exhibited a potent topical anti-inflammatory activity related to inhibition of leukocyte accumulation. The other compounds showed a lower potency, similar to that of indomethacin. None of the compounds affected superoxide generation by human neutrophils but pacifenol effectively inhibited the degranulation response. This compound and epitaondiol decreased the release of eicosanoids with a higher potency on the cyclo-oxygenase pathway. Only epitaondiol inhibited human recombinant synovial phospholipase A2 activity in a concentration-dependen…

Enhancement of immunohistochemical staining

1982

The present paper describes two simple procedures which enhance immunohistochemical staining. One is to cover the sections with a plastic film to keep the serum uniformly distributed and minimize its evaporation. Secondly, rocking of the slides has been introduced, causing the serum to flow back and forth under the plastic film. Using this system, it has been possible to test for the effect of mixing on an immunohistochemical reaction (the demonstration of calcitonin in thyroid C cells). It has been found that mixing definitely enhances the reaction during the first 8 h. No effect of serum volume was observed.

Vetera rerum exempla. La cultura antiquaria fra Bologna e l’Europa nei secoli XV-XVII

2010

Alcuni dotti di Bologna, attivi presso la corte bentivolesca, indagarono le fasi più remote della loro città, con forzature fantasiose ma anche con un’attenzione per i resti materiali di epoca romana. Il vivo interesse per le origini della propria città e per le testimonianze antiche della sua storia (fra le quali assumevano un’importanza crescente i documenti epigrafici) era condiviso da molti altri intellettuali in Germania e nei Paesi Bassi, molti dei quali almeno in parte si erano formati presso lo Studio bolognese. Se è difficile stabilire quale sia stato lo specifico apporto bolognese nella maturazione dell’interesse per l’antico di questi personaggi, a Bologna può in ogni caso essere…
