in A l>sreactive with epitopes expressed on tumor vessels were evaluated as universal delivery agents of peptides with vasoactive properties to enhance the uptake of macromolecules in tumors. Unlike other reported approaches to target tumor vessels, a mAb designated TV-1 targets a basement membrane antigen that is found in all tissues but that is acces sible only in tumor vessels, making it an ...

In contrast to the overwhelming success of radiolabeled antibodies in treating hematologic malignancies, only modest success has been achieved in the radioimmunotherapy of solid tumors. One of the major limitations in successful application of radioimmunotherapy is the large molecular size of the intact immunoglobulin that results in prolonged serum half-life and poor tumor penetration and upta...

p53 and pcna expression in keratocystic odontogenic tumors compared with selected odontogenic cysts summary: the aim of this study was to evaluate p53 and pcna expression in different odontogenic lesions regarding their different clinical behaviors. slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (rc), 23 dentigerous cysts (dc), 23 keratocystic odontogenic tumors (kc...

PURPOSE We recently reported that anionic phospholipids, principally phosphatidylserine, become exposed on the external surface of vascular endothelial cells in tumors, probably in response to oxidative stresses present in the tumor microenvironment. In the present study, we tested the hypothesis that a chimeric monoclonal antibody that binds phosphatidylserine could be labeled with radioactive...

BACKGROUND/AIM Study of the association between Epstein-Barr virus (EBV) and the tumors of the nasopharynx renders an opportunity to introduce causal treatment Already have been proven the anti-EBV (anti-Epstein-Barr nucleus antigene) antibodies in the blood serum of the patients infected with EBV, while over 91% of the patients with nasopharyngeal malignant tumors also have a detectable anti-E...

INTRODUCTION Systemic malignant diseases cause the induction of autoimmunity, for example, paraneoplastic syndromes. There are no proofs of paraneoplastic syndromes in primary brain tumors. The aim of the study was to evaluate the involvement of the peripheral nervous system, together with an assessment of onconeuronal and antineural antibodies as indicators of humoral immune response against n...

Seventy-six female patients with two or more recurrent pregnancy losses (RPL) during the 1(st) trimester were studied. Based on the results of the aCL and aB2GPI antibodies testing, patients were divided in two groups: 22 patients with RPL and elevated immunoglobulin (Ig) G/IgM aCL and/or aB2GPI [RPL + antiphospholipid syndrome (APS)] and 54 patients with RPL alone (without high antibodies). Im...

patients with malignancy are at higher risk of thrombotic complications due to the hypercoagulability state. our objective in this study was to assess the serum concentrations of homocysteine, anti phospholipid antibodies, and anti cardiolipin in patients with benign and malignant breast tumors and study the effect of chemotherapy on the serum levels of these markers. a case control study was c...

OBJECTIVE Study of the hen immune system led to seminal contributions to basic immunological principles. Recent studies of spontaneous ovarian cancer in the laying hen show strikingly similar tumor types and antigen expression compared to human ovarian cancer, suggesting hens would be valuable for studies of tumor immunology and pre-clinical vaccine development. Circulating mesothelin is a rela...

Monoclonal antibodies which bind to breast cancer have been used to evaluate the detection of metastatic disease in axillary lymph nodes. Three monoclonal antibodies (H59, H71, and H72) were reacted with tissue sections of primary tumors and axillary nodes from 24 mastectomy specimens and four specimens from glandular mastectomies for benign disease. All three antibodies had been shown to react...
