Early suppression of lymphoproliferative response in dogs with natural infection by Leishmania infantum.
Dogs are the domestic reservoirs of zoonotic visceral leishmaniasis caused by Leishmania
infantum. Early detection of canine infections evolving to clinically patent disease may be
important to leishmaniasis control. In this study we firstly investigated the peripheral blood
mononuclear cell (PBMC) response to leishmanial antigens and to polyclonal activators
concanavalin A, phytohemagglutinin and pokeweed mitogen, of mixed-breed dogs with natural
L. infantum infection, either in presymptomatic or in patent disease condition, compared to healthy
animals. Leishmania antigens did not induce a clear proliferative response in any of the animals
examined. Furthermore, mitogen-induced lymphocyte proliferation was found strongly reduced not
only in symptomatic, but also in presymptomatic dogs suggesting that the cell-mediated immunity
is suppressed in progressive canine leishmaniasis. To test this finding, naive Beagle dogs were
exposed to natural L. infantum infection in a highly endemic area of southern Italy. Two to 10
months after exposure all dogs were found to be infected by Leishmania, and on month 2 of
exposure they all showed a significant reduction in PBMC activation by mitogens. Our results
indicate that suppression of the lymphoproliferative response is a common occurrence in dogs
already at the beginning of an established leishmanial infection. # 1999 Elsevier Science B.V. All

Fotemustine plus etoposide, cytarabine and melphalan (FEAM) as a new conditioning regimen for lymphoma patients undergoing auto-SCT: A multicenter feasibility study
BEAM is a widely used conditioning regimen for relapsed/refractory lymphoma patients undergoing auto-SCT. We conducted a multicenter study with an alternative regimen (fotemustine plus etoposide, cytarabine and melphalan (FEAM)) in which BCNU was substituted by the chloroethylnitrosourea fotemustine (FTM). Eighty-four patients with relapsed/refractory Hodgkin's (n20) and non-Hodgkin's lymphoma (n64) were conditioned with a FEAM regimen (FTM 150 mg/m 2 on days -7, -6, etoposide 200 mg/m 2 and cytarabine 400 mg/m 2 on days -5, -4, -3, -2 and melphalan 140 mg/m 2 on day -1). Patients were evaluated for toxicity and engraftment parameters. Median times to neutrophil (500 × 10 9 /l) and plt (20 000 × 10 9 /l) engraftment were 11 and 13 days, respectively. Grade 3 mucositis occurred in 19 patients (23%), while G3 nausea/vomiting and G3 diarrhea were observed in 13 (15%) and 6 (7%) patients, respectively. No severe hepatic, renal or pulmonary toxicity was detected. Seven patients (7%) experienced G4 mucositis, while no other G4 toxicities or unexpected adverse events of any grade were recorded. Transplant-related mortality was 2.4%. We conclude that a FEAM regimen is feasible and safe. Although toxicity and engraftment times compared favorably with BEAM, longer follow-up is needed to evaluate fully its efficacy and long-term safety. © 2010 Macmillan Publishers Limited All rights reserved

Asymmetric nuclear matter in a Hartree-Fock approach to non-linear QHD
The Equation of State (EOS) for asymmetric nuclear matter is discussed
starting from a phenomenological hadronic field theory of Serot-Walecka type
including exchange terms. In a model with self interactions of the scalar
sigma-meson we show that the Fock terms naturally lead to isospin effects in
the nuclear EOS. These effects are quite large and dominate over the
contribution due to isovector mesons. We obtain a potential symmetry term of
"stiff" type, i.e. increasing with baryon density and an interesting behaviour
of neutron/proton effective masses of relevance for transport properties of
asymmetric dense matter.Comment: 12 pages (LATEX), 3 Postscript figures, revised versio
Perilipin 2 levels are increased in patients with in-stent neoatherosclerosis: A clue to mechanisms of accelerated plaque formation after drug-eluting stent implantation
Background: Perilipin 2 (PLIN2) is a protein that potentially facilitates atherogenesis in native coronary arteries or arteries with an implanted drug-eluting stent (DES). The aim of the study was to determine PLIN2 protein levels in peripheral monocytes of enrolled subjects and compare them between patients with native coronary artery disease (CAD) and those with an in-stent restenosis (ISR) due to neoatherosclerosis occurring >1 year after DES implantation. Methods: Forty-two patients were prospectively enrolled in the study in 3:1 fashion and underwent coronary catheterization. Both groups were angiographically matched for CAD burden with respect to the number of diseased vessels. Neoatherosclerosis was determined by intracoronary optical coherence tomography (OCT) among patients with ISR. Results: Patients with ISR due to neoatherosclerosis had significantly higher PLIN2 protein levels in peripheral blood monocytes compared to patients with native CAD (342.47 ± 75.63[SE] versus 119.51 ± 20.95, p < 0.001). PLIN2 protein levels did not significantly differ between unstable and stable disease phenotype (125.59 ± 131.02 vs. 146.14 ± 111.87, p = 0.109). Conclusions: In this explorative study, PLIN2 protein levels are significantly increased in patients with neoatherosclerosis, irrespective of clinical presentation, implicating that it might play a pathogenetic role in accelerated atherosclerosis after DES implantation. Further larger clinical studies are warranted to confirm these initial findings
