Humoral immune responses of lung cancer patients against tumor antigen NY-ESO-1
2005
The cancer-associated antigen NY-ESO-1 is expressed in a number of malignancies of different histological type. Patients with NY-ESO-1 expressing tumors have been shown to bear circulating autoantibodies against this antigen. In this study, we have assessed the NY-ESO-I autoantibody response in patients with lung cancer by a serum ELISA. Using a serum dilution of 1:400 we detected seroreactivity in 35 of 175 (20%) of patients. Incidence of autoantibodies was significantly higher in patients suffering from non small cell lung cancer (NSCLC, 23%) as compared to those with small cell lung cancer (SCLC, 9%). In the NSCLC group, NY-ESO-I antibody was significantly more frequent in patients with …
Expression of insulin-like growth factor system components in Ewing's sarcoma and their association with survival.
2010
Abstract Aims The role of IGF system in the pathogenesis of Ewing’s sarcoma (EWS) is well-documented. However, still little information is available about the value of IGF system components as indicators of prognosis. Understanding the clinical role for IGF system in EWS patients may be important because different subtypes of patients have distinct outcome and may require different treatment protocol. We evaluated the expression of insulin-like growth factor (IGF)-receptor (IGF-IR), insulin receptor (IR), IGF-I and some major intracellular mediators (IRS1, p-ERK) in specimens from EWS patients with primary localised untreated tumours. Patients and methods 290 samples were used for immunohis…
Circulating interleukin (IL)-8, IL-2R, IL-12, and IL-15 levels are independently prognostic in primary myelofibrosis: a comprehensive cytokine profil…
2011
Purpose Abnormal cytokine expression accompanies myelofibrosis and might be a therapeutic target for Janus-associated kinase (JAK) inhibitor drugs. This study describes the spectrum of plasma cytokine abnormalities in primary myelofibrosis (PMF) and examines their phenotypic correlates and prognostic significance. Patients and Methods Patients included in this study were required to have archived plasma, bone marrow biopsy, and cytogenetic information available at the time of first referral to the Mayo Clinic. Multiplex biometric sandwich immunoassay was used to measure plasma levels of 30 cytokines. Results In total, 127 PMF patients were studied; comparison with normal controls (n = 35) r…
Complete congenital heart block is associated with increased autoantibody titers against calreticulin.
1996
Complete congenital heart block (CCHB) is associated with anti-Ro/SS-A and anti-La/SS-B antibodies. Calreticulin, a calcium-binding, multi-functional protein of the endoplasmic reticulum with C-terminal KDEL-sequence, is not part of the Ro/SS-A ribonucleoprotein complex. In this study anti-calreticulin autoantibody responses in serum samples from 18 infants with CCHB, their mothers and in a control group of 11 anti-Ro/SS-A or anti-La/SS-B positive infants without heart block and their mothers were analysed. Specific enzyme-linked immunosorbent assays were performed. Nine out of 18 sera with CCHB contained IgG anti-calreticulin antibodies. Four sera of those with IgG antibodies also had IgM …
Subtyping of group specific component (GC) in human semen, blood and vaginal fluid by isoelectric focusing in immobilized pH gradients.
1988
The group specific component (GC) is stable and well suited for forensic casework. Isoelectric focusing of common GC variants from semen, seminal fluid, vaginal fluid and semen stains, on Immobiline DryPlates, pH 4.5-5.4, is of practical value in criminal investigations of sexual deliquencies. GC is present in normospermia and azoospermia seminal fluids and found in about 20% of the vaginal secretions. The GC patterns observed were similar and in accordance with the bands of the individual GC type in plasma/serum.
An insight into the epidemiology of dolphin morbillivirus worldwide.
2001
Serum samples from 288 cetaceans representing 25 species and originating from 11 different countries were collected between 1995 and 1999 and examined for the presence of dolphin morbillivirus (DMV)-specific antibodies by an indirect ELISA (iELISA) (N=267) or a plaque reduction assay (N=21). A total of 35 odontocetes were seropositive: three harbour porpoises (Phocoena phocoena) and a common dolphin (Delphinus delphis) from the Northeastern (NE) Atlantic, a bottlenose dolphin (Tursiops truncatus) from Kent (England), three striped dolphins (Stenella coeruleoalba), two Risso’s dolphins (Grampus griseus) and a bottlenose dolphin from the Mediterranean Sea, one common dolphin from the Southwes…
Hypertensive status and lipoprotein oxidation in an elderly population at high cardiovascular risk.
2008
BACKGROUND: In elderly individuals, hypertension is a main risk factor for cardiovascular disease and oxidative damage is increased. Our aim was to assess the relationship between the degree of in vivo low-density lipoprotein (oxLDL) oxidation and the hypertensive status in a elderly population at high cardiovascular risk. METHODS: Cross-sectional study with baseline data from the PREDIMED (PREvención con DIeta MEDiterránea) trial, an intervention study directed at testing the efficacy of the Mediterranean diet on the primary prevention of cardiovascular disease. Participants were 1,130 subjects at high cardiovascular risk aged 55-80. At baseline, in vivo circulating oxLDL was measured, and…
Diagnosis of human fascioliasis by stool and blood techniques: update for the present global scenario
2014
SUMMARYBefore the 1990s, human fascioliasis diagnosis focused on individual patients in hospitals or health centres. Case reports were mainly from developed countries and usually concerned isolated human infection in animal endemic areas. From the mid-1990s onwards, due to the progressive description of human endemic areas and human infection reports in developing countries, but also new knowledge on clinical manifestations and pathology, new situations, hitherto neglected, entered in the global scenario. Human fascioliasis has proved to be pronouncedly more heterogeneous than previously thought, including different transmission patterns and epidemiological situations. Stool and blood techn…
The effect of glycosylation of antigens on the antibody responses against Echinostoma caproni (Trematoda: Echinostomatidae).
2014
SUMMARYIn the present study, we analyse the effect of glycosylation inEchinostoma caproni(Trematoda: Echinostomatidae) antigens in antibody responses against the parasite in experimentally infected mice. It has been previously demonstrated that the mouse is a host of high compatibility withE. caproniand develops elevated responses of IgG, IgG1, IgG3 and IgM as a consequence of the infection, though the role of glycans in these responses remains unknown. To this purpose, the responses generated in mice against non-treated excretory/secretory antigens ofE. caproniwere compared with those observed after N-deglycosylation, O-deglycosylation and double deglycosylation of the antigens by indirect…
Immunogenicity and reactogenicity of a Haemophilus influenzae type b tetanus conjugate vaccine when administered separately or mixed with concomitant…
1998
With an increasing number of new vaccines available for routine childhood immunization, combination vaccines are needed in order to maintain or achieve a high compliance with recommended immunization programmes. In a prospective, randomized, comparative, multi-centre study, 822 healthy infants were enrolled to receive three doses of either a candidate or a commercially available Haemophilus influenzae type b (Hib) vaccine concomitantly with diphtheria-, tetanus- acellular pertussis (DTaP) vaccine. Study subjects were randomly allocated to one of the following groups: (1) separate, or (2) mixed injection of DTaP and candidate Hib vaccine, or (3) separate injection of DTaP and commercial Hib …
