Enhancement of Wound Healing in Normal and Diabetic Mice by Topical Application of Amorphous Polyphosphate. Superior Effect of a Host⁻Guest Composite…
2017
The effect of polyphosphate (polyP) microparticles on wound healing was tested both in vitro and in a mice model in vivo. Two approaches were used: pure salts of polyphosphate, fabricated as amorphous microparticles (MPs, consisting of calcium and magnesium salts of polyP, “Ca–polyp-MPs” and “Mg–polyp-MPs”), and host–guest composite particles, prepared from amorphous collagen (host) and polyphosphate (guest), termed “col/polyp-MPs”. Animal experiments with polyP on healing of excisional wounds were performed using both normal mice and diabetic mice. After a healing period of 7 days “Ca–polyp-MP” significantly improved re-epithelialization in normal mice from 31% (control) to 72% (polyP micr…
The association between the 4G/5G polymorphism in the promoter of the plasminogen activator inhibitor-1 gene and extension of postsurgical calf vein …
2013
The objective of this study was to evaluate whether the presence of a plasminogen activator inhibitor type 1 (PAI-1) promoter polymorphism 4G/5G could significantly influence the proximal extension of vein thrombosis in spite of anticoagulant treatment in patients with calf vein thrombosis (CVT) following orthopaedic, urological and abdominal surgery. We studied 168 patients with CVT, who had undergone orthopaedic, urological and abdominal surgery, subdivided as follows: first, 50 patients with thrombosis progression; second, 118 patients without thrombosis progression. The 4G/5G polymorphism of the plasminogen activator inhibitor 1 was evaluated in all patients and in 70 healthy matched co…
Influence of genetic polymorphisms and mutations in the cardiac pathology of iron overload in thalassemia and sickle cell anemia patients: a retrospe…
2012
Cardiac disease in thalassemia is determined by the accumulation of iron in the tissue. Genetic factors could influence the severity and the rapidity of the modifications of the cardiac tissue. Mutations or polymorphisms of genes have already been described as being implicated in cardiac disease. In particular, we studied the polymorphisms C1091T in the Connexin 37 gene (CX 37), 4G -668 5G in the Plasminogen Activator Inhibitor-1 gene (PAI 1) and 5A-1171 6A in the Stromelysin-1 gene (SL) in 193 randomly selected patients affected by hemoglobinopathies and 100 normal subjects randomly selected from the general population. A retrospective analysis based on history, clinical data and imaging s…
