Nalidixic acid and oxolinic acid, two antibacterial agents known to inhibit bacterial DNA gyrase, are shown to suppress the replication, as well as the cytopathic effect, of BK virus in Vero cell cultures. The inhibition of virus replication was detectable at day 4 post infection in cultures which had been continuously exposed to drugs at concentrations as(More)
The risk of retinopathy associated with the use of hydroxychloroquine is said to be nullified if the dosage recommendations are followed strictly. In this case report, we describe an elderly patient with rheumatoid arthritis who had bilateral maculopathy, presumably secondary to hydroxychloroquine therapy, despite a dosing regimen within therapeutic(More)
OBJECTIVE Abatacept (ABA) is a chimeric molecule, able to block the CD28-mediated costimulatory pathway. To evaluate the hypothesis that, through this mechanism of action, ABA may down-modulate the immune responses of B lymphocytes in rheumatoid arthritis (RA), we investigated the serum levels of immunoglobulins (Ig), free light chains (FLC),(More)
Plasma cell dyscrasias are immunosecretory disorders that can lead to hematological malignancies such as Multiple Myeloma (MM). MM accounts for 15% of all hematologic cancers, and those diagnosed with MM typically become severely ill and have a low life expectancy. Monoclonal immunoglobulin Free Light Chains (FLC) are present in the serum and urine of many(More)
Multiple myeloma (MM) is a hematological malignancy caused by a microenviromentally aided persistence of plasma cells in the bone marrow. Monoclonal plasma cells often secrete high amounts of immunoglobulin free light chains (FLCs) that could induce tissue damage. Recently, we showed that FLCs are internalized in endothelial and myocardial cell lines and(More)
BACKGROUND Heavy/light chain assay allows the characterization and quantification of immunoglobulin light chains bound to heavy chains for each Ig'k and Ig'λ immunoglobulin class, discriminating between the involved/uninvolved isotypes in plasma cell dyscrasia. The Ig'k/Ig'λ ratio (heavy/light chain ratio) enables to monitor the trend of monoclonal(More)
Exosomes are gaining a prominent role in research due to their intriguing biology and several therapeutic opportunities. However, their accurate purification from body fluids and detailed physicochemical characterization remain open issues. We isolated exosomes from serum of patients with Multiple Myeloma by four of the most popular purification methods and(More)
Extracellular Vesicles (EVs) - cell secreted vesicles that carry rich molecular information of the parental cell and constitute an important mode of intercellular communication - are becoming a primary topic in translational medicine. EVs (that comprise exosomes and microvesicles/microparticles) have a size ranging from 40 nm to 1 μm and share several(More)
Adaptor protein (AP) complexes are key factors for the spatial and temporal regulation of intracellular trafficking events. Four complexes (AP-1, -2, -3, -4) are known, among which AP-4 is only poorly characterized. Recent work suggests a role for AP-4 in the intracellular trafficking of the β-amyloid precursor protein and molecular genetics showed that the(More)
OBJECTIVE To report a case of phenolphthalein-induced toxic epidermal necrolysis (TEN) in a patient maintained on several other medications more commonly known to be associated with TEN. CASE SUMMARY A 78-year-old white man presented with intractable lower back pain and constipation. On day 1 of admission, the patient exhibited a diffuse urticarial rash(More)
