Lauryl gallate is an antioxidant food additive showing low toxicity to normal cells. Here, its antiproliferative effect has been studied on three human breast cancer cell lines: estrogen-dependent, wild-type p53, MCF7; estrogen-independent, non-functional p53, MDA-MB-231 and MCF7 ADR, which overexpresses P-glycoprotein (P-gp) and displays a(More)
BACKGROUND Patients with a clinically isolated demyelinating syndrome (CIS) are at risk of developing a second attack, thus converting into clinically definite multiple sclerosis (CDMS). Therefore, an accurate prognostic marker for that conversion might allow early treatment. Brain MRI and oligoclonal IgG band (OCGB) detection are the most frequent(More)
Intrathecal IgM synthesis (ITMS) predicts a worse evolution in the first stages of multiple sclerosis (MS). The aim of this study was the follow-up of a group of relapsing-remitting MS patients for a longer time to evaluate whether the ITMS implies a poor prognosis. Oligoclonal IgM bands were performed in 29 MS patients followed up from 5 to 16 years. Time(More)
Demonstration of lesion dissemination in space (DIS) and time (DIT) is necessary for the diagnosis of multiple sclerosis (MS) in clinically isolated syndromes (CIS). The McDonald criteria accepted two methods to demonstrate DIS. The fulfillment of at least three of four MRI Barkhof criteria (MRI-BC) or, alternatively, the finding of at least two MRI lesions(More)
BACKGROUND Intrathecal IgG synthesis (ITGS), in conjunction with magnetic resonance imaging, can help in the early diagnosis of multiple sclerosis (MS). Recently, we developed a new oligoclonal IgG band (OCGB) test for ITGS detection that is more sensitive and easier to interpret than previously described methods. OBJECTIVE To assess the accuracy of a new(More)
The authors studied the intrathecal IgM synthesis (ITMS) in paired sera and CSF samples from 65 patients with MS, 28 with CNS infection, 40 with other neurologic diseases and eight control subjects. ITMS was found in 30 patients with MS and in 20 with CNS infection, but not in patients with other neurologic diseases or in control subjects. In infectious(More)
BACKGROUND The authors have recently described that intrathecal IgM synthesis (ITMS) correlates with a higher disability in patients with clinically definite MS (CDMS). OBJECTIVE To follow-up a group of patients with MS in the initial stages of the disease to evaluate if the presence of ITMS correlates with a worse evolution. METHODS Oligoclonal IgM(More)
Oligoclonal IgG bands (OCGB) are characteristic of multiple sclerosis (MS). Most patients show OCGB exclusively in cerebrospinal fluid (CSF). Others have serum bands with additional ones in CSF. Moreover, IgM bands against myelin lipids (LS-OCMB) associate with aggressive relapsing-remitting MS (RRMS). We studied oligoclonal bands in 424 MS patients. Most(More)
Tumoral lymphocytes from patients with B-chronic lymphocytic leukemia (B-CLL) are long-lived cells in vivo, but they die rapidly by apoptosis in vitro. Here, it is reported that endothelial cells (ECs) inhibit the apoptosis of B-CLL cells, as determined by 4 different flow cytometric methods, and that this antiapoptotic effect is mediated mainly by soluble(More)
We have studied the intrathecal synthesis of soluble class I antigens (sHLA), reflected by the index IH = (CSF sHLA/serum sHLA)/(CSF albumin/serum albumin), in multiple sclerosis (MS). IH was increased in patients in relapse, but normal in patients in remission; these findings show that there is a high lymphocyte activation within the central nervous system(More)
