Mapping landscape canopy nitrogen content from space using PRISMA data
2021
Abstract Satellite imaging spectroscopy for terrestrial applications is reaching maturity with recently launched and upcoming science-driven missions, e.g. PRecursore IperSpettrale della Missione Applicativa (PRISMA) and Environmental Mapping and Analysis Program (EnMAP), respectively. Moreover, the high-priority mission candidate Copernicus Hyperspectral Imaging Mission for the Environment (CHIME) is expected to globally provide routine hyperspectral observations to support new and enhanced services for, among others, sustainable agricultural and biodiversity management. Thanks to the provision of contiguous visible-to-shortwave infrared spectral data, hyperspectral missions open enhanced …
Genotypic and Phenotypic Characteristics of Acute Promyelocytic Leukemia Translocation Variants.
2020
Acute promyelocytic leukemia (APL) is a special disease entity of acute myeloid leukemia (AML). The clinical use of all-trans retinoic acid (ATRA) has transformed APL into the most curable form of AML. The majority of APL cases are characterized by the fusion gene PML-RARA. Although the PML-RARA fusion gene can be detected in almost all APL cases, translocation variants of APL have been reported. To date, this is the most comprehensive review of these translocations, discussing 15 different variants. Reviewed genes involved in APL variants include: ZBTB16, NPM, NuMA, STAT5b, PRKAR1A, FIP1L1, BCOR, NABP1, TBLR1, GTF2I, IRF2BP2, FNDC3B, ADAMDTS17, STAT3, and TFG. The genotypic and phenotypic …
Pre-Emptive Immunotherapy for Clearance of Molecular Disease in Childhood Acute Lymphoblastic Leukemia after Transplantation
2016
Abstract Monitoring of minimal residual disease (MRD) or chimerism may help guide pre-emptive immunotherapy (IT) with a view to preventing relapse in childhood acute lymphoblastic leukemia (ALL) after transplantation. Patients with ALL who consecutively underwent transplantation in Frankfurt/Main, Germany between January 1, 2005 and July 1, 2014 were included in this retrospective study. Chimerism monitoring was performed in all, and MRD assessment was performed in 58 of 89 patients. IT was guided in 19 of 24 patients with mixed chimerism (MC) and MRD and by MRD only in another 4 patients with complete chimerism (CC). The 3-year probabilities of event-free survival (EFS) were .69 ± .06 for …
Significance of increased blastic-appearing cells in bone marrow following myeloablative unrelated cord blood transplantation in adult patients.
2012
An abnormal increase of nonleukemic blastic-appearing lymphocytes in bone marrow (BM) specimens has been reported after unrelated cord blood transplantation (UCBT). This study analyzed the incidence, chronology, biological features, and clinical significance of elevated numbers of these cells in a series of 165 consecutive adult patients demonstrating myeloid engraftment after myeloablative UCBT in a single institution. The patients' BM samples were routinely evaluated by cytomorphology at different time points after UCBT. When ≥5% of blastic-appearing cells were detected by cytomorphology in the BM, samples were also evaluated by multiparametric flow cytometry to characterize these cells. …
Prophylactic chimera anterolateral thigh/vastus lateralis flap: preventing complications in high-risk head and neck reconstruction
2014
Purpose In high-risk head and neck cases treated with tumor resection and associated radical neck dissection, orocutaneous fistulas and wound breakdowns in the neck are relatively frequent and can have serious consequences, such as carotid blowout syndrome (CBS), the need for salvage reoperations, and prolonged recovery time. The authors present the application of a prophylactic chimeric anterolateral thigh (ALT) and vastus lateralis (VL) flap to prevent complications. Materials and Methods A retrospective review was performed of a historical group (96 patients) of patients with head and neck cancer treated with tumor resection, radical neck dissection, and microsurgical reconstruction of t…
Failure of sustained engraftment after non-myeloablative conditioning with low-dose TBI and T cell-reduced allogeneic peripheral stem cell transplant…
2001
We investigated whether a T cell-reduced allogeneic stem cell transplant (SCT) with minimal conditioning and subsequent donor lymphocyte infusions (DLI) could reduce the incidence and severity of GVHD while retaining stable engraftment. Five patients with hematological malignancies (three MM, one CLL, one Chediak-Higashi syndrome) were conditioned with TBI (200 cGy). One patient additionally received fludarabine (120 mg/m(2)). CsA and mofetyl-mycophenolate (MMF) were administered to prevent GVHD. All patients were grafted with >3 x 10(6)/kg highly purified CD34(+) cells together with 2 x 10(6)/kg CD3(+) cells (three patients) or 1 x 10(5)/kg CD3(+) cells (two patients). Quick hematopoietic …

Self-Assembly of Water-Mediated Supramolecular Cationic Archimedean Solids
2013
Understanding the self-assembly of small structural units into large supramolecular assemblies remains one of the great challenges in structural chemistry. We have discovered that tetrahedral supramolecular cages, exhibiting the shapes of Archimedean solids, can be self-assembled by hydrogen bonding interactions using tricationic N-donors (1 or 2) in cooperation with water (W). Single crystal X-ray analysis shows that cage (2)4(W)6, assembled in an aqueous solution of cation 2 and KPF6, consists of four tripodal trications linked by six water monomers and resembles the shape of a truncated tetrahedron. Similarly, cage (1)4(W6)4 spontaneously self-assembles in an aqueous solution of cation 1…
Prefazione. Filosofia e scienza in Domenico Scinà
2016
Nel corso della storia della cultura occidentale possiamo riscontrare filosofi che furono anche poeti (Empedocle, Parmenide) o poeti che furono anche filosofi (Omero, Esiodo). Perciò le discipline il più delle volte non sono facilmente delimitabili, così come accade leggendo le Purificazioni di Empedocle o il poema Sulla natura di Parmenide. Nell’ambito della letteratura troviamo “briciole” di poesia che hanno determinato suggestioni e riflessioni non marginali: in questo caso la memoria suggerisce la rilettura de Il lamento di Danae del poeta greco Simonide di Ceo o de L’infinito del poeta italiano Giacomo Leopardi. In tal senso potremmo soffermarci sulla reinterpretazione che delle traged…
