BACKGROUND Both urinary bilharziasis and urothelial neoplasia are associated with increased production of tissue carcinoembryonic antigen (CEA). PATIENTS AND METHODS Urine and serum CEA were determined in 43 patients with urinary bladder carcinoma including 22 post bilharzial and 21 nonbiharzial cases, in addition to 10 normal control cases. RESULTS A significant increase was detected in bo...

Interleukin-2 (IL-2) has been an effective immune modulator in several active-specific immunotherapy experimental protocols using either viral or oncolysate-based vaccines. In this report, data indicate that IL-2 administration can appreciably augment the therapeutic effect of a single immunization of a recombinant vaccinia virus-carcinoembryonic antigen (rV-CEA) vaccine using a CEA-expressing ...

Objective(s): Central nucleus of amygdala (CeA) is the most important region for morphine-induced reward, and GABAergic system plays an important role on morphine reinforcement. The influence of CeA administration of GABAB receptor agonist and antagonist on the expression and acquisition of morphine-induced incentive tolerance using conditioned place preference (CPP) paradigm was investigated i...

Internal carotid artery (ICA) stenosis often presents bilaterally and is a major cause of stroke. Carotid duplex ultrasound used for estimation via peak systolic velocity (PSV), end diastolic (EDV), ICA/common (CCA) ratio. endarterectomy (CEA) common surgery ICA carries high risk stroke mortality. In near occlusion with >90% stenosis, collateral flow through contralateral can compensate increas...

MEDI-565 (also known as MT111) is a bispecific T-cell engager (BiTE®) antibody in development for the treatment of patients with cancers expressing carcinoembryonic antigen (CEA). MEDI-565 binds CEA on cancer cells and CD3 on T cells to induce T-cell mediated killing of cancer cells. To understand the molecular basis of human CEA recognition by MEDI-565 and how polymorphisms and spliced forms o...

In this report, we have studied the immunogenicity of the nominal antigen, carcinoembryonic antigen (CEA), and that of an anti-idiotype antibody, 3H1, which mimics CEA and can be used as a surrogate for CEA. We have demonstrated that immunization of CEA transgenic mice with bone marrow-derived mature dendritic cells (DC) loaded with anti-idiotype 3H1 or CEA could reverse CEA unresponsiveness an...

BACKGROUND Cost effectiveness analysis (CEA) is a useful tool for allocation of constrained resources, yet CEA methodologies are rarely taught or implemented in developing nations. We aimed to assess exposure to, and interest in CEA, and identify barriers to implementation in Uganda. METHODS A cross-sectional survey was carried out in Uganda using a newly developed self-administered questionn...

By virtue of its tissue-specific expression, carcinoembryonic antigen (CEA) is an important self, tumor-associated antigen, which is expressed by different human adenocarcinomas and also serves as a target for active-specific immunotherapy. Similar to humans, CEA expression in mice transgenic for the human CEA gene (CEA.Tg) occurs predominantly along the gastrointestinal tract. CEA.Tg mice were...

Objectives: Carcinoembryonic antigen (CEA) is widely used for postoperative surveillance of colon cancer. Even if serum CEA is negative at initial surgery, it may turn positive at recurrence. We investigated the relation between serum CEA levels and the immunohistochemical staining status of CEA in the primary and resected metastatic tissues. Methods : Out of 224 patients with recurrent colon c...
