Poly(I:C) and CpG-ODN combined aerosolization to treat lung metastases and counter the immunosuppressive microenvironment.
2015
The immunostimulatory ability of synthetic oligonucleotides containing CpG motifs (CpG-ODN), agonists of Toll-like receptor 9 (TLR9), can be harnessed to promote antitumor immunity by their application at the tumor site to stimulate local activation of innate immunity; however, particularly in the lung, tumor-associated immunosuppression can subvert such antitumor innate immune responses. To locally maintain continuous activation of innate subpopulations while inhibiting immunosuppressive cells, we evaluated aerosol delivery CpG-ODN combined with Poly(I:C), a TLR3 agonist able to convert tumor-supporting macrophages to tumoricidal effectors, in the treatment of B16 melanoma lung metastases …
Synthesis of Biocompatible and Biodegradable Polyamidoamines Microgels via a Simple and Reliable Statistical Approach.
2022
Polyamidoamines (PAAs) are biocompatible and biodegradable polymers with a huge potential as biomaterials for pharmaceutical applications. They are obtained by the step-wise aza-Michael polyaddition of bifunctional or multifunctional amines with bisacrylamides in water. To the best of our knowledge, no synthetic protocols leading to hyperbranched PAAs as well as PAA microgels have been published so far. To fill this gap, a statistical approach was established in this work to fine-tune the aza-Michael polyaddition stoichiometry when a multifunctional co-monomer (bf) is added to a mixture of bifunctional monomers with complementary functions (a2 + b2), possibly even in presence of a monofunct…
Isolation and characterization of microsatellite markers in the liver fluke (Fasciola hepatica)
2004
PRIMER NOTE; International audience; Six microsatellite markers were isolated from Fasciola hepatica, a re-emerging parasite that causes important veterinary and public health problems. In a sample of 52 liver flukes from a region of hyperendemicity (Bolivian Altiplano), five microsatellite were polymorphic. Our results showed that liver flukes present important genetic variability, suggesting a preferential outcrossing reproduction mode for this hermaphroditic parasite.

Schede sintetiche delle Piattaforme Territoriali Strategiche. Piattaforma C4 Sicilia Occidentale
2010
L'articolo si riferisce al lavoro dell'autore come componente della Commissione nazionale sulle Infrastrutture dell'Istituto Nazionale di Urbanistica che ha esaminato la parte delle politiche del Ministero delle Infrastrutture sulle politiche da intraprendere per i trasporti nella punta della sicilia occidentale.Il volume di Urbanistica Dossier contiene tutte le schede redatte dai componenti della Commissione nazionale. Il lavoro consiste nell'analisi territoriale dello stato attuale del livello di infrastrutturazione per i trasporti attuale e un esame il più possibile completo delle politiche avviate e dei loro effetti. L'obiettivo principale dell'analisi è valutare se nelle realtà regiona…

Rational Chemical Multifunctionalization of Graphene Interface Enhances Targeted Cancer Therapy
2020
The synthesis of a drug delivery platform based on graphene was achieved through a step‐by‐step strategy of selective amine deprotection and functionalization. The multifunctional graphene platform, functionalized with indocyanine green, folic acid, and doxorubicin showed an enhanced anticancer activity. The remarkable targeting capacity for cancer cells in combination with the synergistic effect of drug release and photothermal properties prove the great advantage of a combined chemo‐ and phototherapy based on graphene against cancer, opening the doors to future therapeutic applications of this type of material.
Marked elevation of transaminases and pancreatic enzymes in severe malnourished male with eating disorder
2013
We report a case of a 45 year old Caucasian malnourished male with an history of eating disorder who developed severe liver and pancreatic damage and multiorgan disfunction. At admission to our department, his body mass index (BMI) was 11.1. Biochemical evaluation showed elevated serum levels of transaminases (AST= 2291 U/L, ALT= 1792 U/L), amylase (3620 U/L), lipase (4102 U/L), CPK= 1370 U/L, LDH= 2082 U/L. No other cause of acute liver and pancreatic damage was evidenced. Haematological disorders (anemia, thrombocytopenia, leukopenia) found on admission seem related to bone marrow hypoplasia and to gelatinous marrow transformation described in severe state of malnutrition. Although a mode…
Practical Considerations for the Daratumumab Management in Portuguese Routine Clinical Practice: Recommendations From an Expert Panel of Hematologists
2022
The recent therapeutic progress in multiple myeloma (MM) has led to the introduction of novel and highly potent drug classes. Daratumumab was the first CD38-targeting antibody showing to be effective and safe in MM patients as monotherapy and in combination regimens, which led to its rapid implementation in clinical practice. Considering that treatment discontinuation for drug-related adverse events can impact patients’ quality of life and outcomes, the treatment decision should consider different factors and be weighted for each patient individually. Here, we aimed to guide clinicians using daratumumab treatment for MM by addressing practical real-world considerations based on an expert pa…
ShRNA-mediated knock-down of CXCL8 inhibits tumor growth in colorectal liver metastasis.
2018
CXCL8 belongs to proinflammatory chemokines that are predominantly involved in neutrophil chemotaxis and degranulation. Several studies have suggested that secretion of CXCL8 from cancer cells have a profound effect on tumor microenvironment. In this study, in continuation to our previous work of understanding the global picture of invasion related genes in colorectal liver metastases, we clearly show an up-regulation of CXCL8 expression in the tumor cells at the invasion front as compared to the tumor cells in the inner parts of the tumor. Furthermore, ShRNA mediated down-regulation of CXCL8 resulted in inhibition of cell proliferation, viability and invasion in vitro and a near complete g…
