Reduction of Atherosclerotic Lesions by the Chemotherapeutic Agent Carmustine Associated to Lipid Nanoparticles.

Purpose: After injection in the bloodstream, a lipid nanoparticle (LDE) resembling low-density lipoprotein (LDL) concentrates in atherosclerotic lesions of cholesterol-fed rabbits. Here, rabbits with atherosclerosis were treated with carmustine, an antiproliferative agent used in cancer chemotherapy, associated to LDE to investigate the effects on the lesions.

Methods: Twenty-seven male New Zealand rabbits were fed a 1 % cholesterol diet for 8 weeks.

Anti-atherogenic effects of methotrexate carried by a lipid nanoemulsion that binds to LDL receptors in cholesterol-fed rabbits.

Purpose: Nanoemulsions (LDE) with a lipid composition resembling that of LDL can concentrate in aortic lesions and when associated with anti-blastic agents, such as paclitaxel or etoposide, decrease atherosclerotic lesions induced in rabbits. Our aim was to test the association of a lipophilic derivative of methotrexate, didodecyl-methotrexate (ddMTX) to LDE on the lesions and on the expression of pro-inflammatory and anti-inflammatory genes.

Methods: Twenty male New Zealand rabbits were fed 1 % cholesterol diet for 60 days.

Intra-articular methotrexate associated to lipid nanoemulsions: anti-inflammatory effect upon antigen-induced arthritis.

Objective: Commercial methotrexate formulations (MTX) have poor anti-inflammatory action for intra-articular treatment of rheumatoid arthritis. Our aim was to investigate whether an association between methotrexate and lipidic nanoemulsions (LDE) could improve MTX intra-articular action.

Methods: For its association to LDE, MTX was previously esterified with dodecyl bromide.

Treatment with methotrexate inhibits atherogenesis in cholesterol-fed rabbits.

A decrease in the number of cardiovascular events in patients with rheumatoid arthritis or psoriasis treated with methotrexate (MTX) has been observed in the literature. The aim of this study was to test whether MTX could promote anti-inflammatory effects and reduce the atherosclerotic lesions in rabbits with atherosclerosis induced by cholesterol feeding. Twenty male New Zealand rabbits were fed a 1% cholesterol diet for 60 days.

Epstein-Barr viral load, interleukin-6 and interleukin-10 levels in post-transplant lymphoproliferative disease: a nested case-control study in a renal transplant cohort.

The possible correlation among Epstein-Barr virus (EBV) load, interleukin-6 (IL-6) and interleukin-10 (IL-10) levels has become an attractive issue and can provide a useful tool for diagnosis and monitoring of patients at risk for post-transplant lymphoproliferative disease (PTLD) development. At the time of diagnosis of PTLD, 11 patients were prospectively enrolled and 55 nested controls were selected from a 1800 renal transplant cohort. Real-time polymerase chain reaction (PCR) was used to quantify EBV load in peripheral blood mononuclear cells (PBMC).

Identification of 9 novel transcripts and two RGSL genes within the hereditary prostate cancer region (HPC1) at 1q25.

We applied a systematic bioinformatics approach, followed by careful manual inspection and experimental validation to identify additional expressed sequences located at the Hereditary Prostate Cancer Region (HPC1) between D1S2818 and D1S1642 on chromosome 1q25. All transcripts already described for the 1q25 region were identified and we were able to define 11 additional expressed sequences within this region (three full-length cDNA clone sequences and eight ESTs), increasing the total number of gene count in this region by 38%. Five out of the 11 expressed sequences identified were shown to be expressed in prostate tissue and thus represent novel disease gene candidates for the HPC1 region.
