CDX2, a highly sensitive and specific marker of adenocarcinomas of intestinal origin - An immunohistochemical survey of 476 primary and metastatic carcinomas
(Lippincott Williams & Wilkins, 2003-03-01)
CDX2 is a recently cloned homeobox gene that encodes an intestine-specific transcription factor, expressed in the nuclei of epithelial cells throughout the intestine, from duodenum to rectum. While expression of CDX2 protein ...
Histopathological and immunohistochemical (cytokeratins AE1/AE3) study of the parametrium of patients with early stage cervical cancer
(Elsevier B.V., 2008-11-01)
Objective: This study was under-taken in order to evaluate histopathological and immunohistochemical (cytokeratins AE1/AE3) characteristics of parametrial invasion in patients with early stage cervical cancer.Study design: ...
Culture of mature trophoblastic giant cells from bovine placentomes
(Elsevier B.V., 2007-04-01)
The mostly binucleate trophoblast giant cells (TGC) found in bovine placentomes, in addition to synthesizing and releasing hormones play an important role in fetal development and maternal adaptation to pregnancy. Placentomes ...
Expression of p53, Ki-67, and CD31 in the vaginal margins of radical hysterectomy in patients with stage IB carcinoma of the cervix
(Elsevier B.V., 2004-12-01)
Objectives. This study was undertaken to evaluate the expression of p53, Ki-67, and CD31 both in the tumor and in the vaginal margins of radical hysterectomy in patients with stage IB squamous cell carcinoma of the cervix, ...
Ultrastructural characterization of CD133(+) stem cells bound to superparamagnetic nanoparticles: possible biotechnological applications
(Blackwell Publishing, 2008-09-01)
CD133 antigen is an integral membrane glycoprotein that can bind with different cells. Originally, however. this cellular surface antigen was expressed in human stem cells and in various cellular progenitors of the ...
REDUCTION OF CELL PROLIFERATIVE ACTIVITIES OF GASTRIC STUMP ADENOMATOUS HYPERPLASIAS AFTER BILE REFLUX DIVERSION IN RATS
(Oxford University Press, 1993-09-01)
Previously we reported the majority of lesions induced hy bile reflux, in the absence of chemical carcinogens, in the rat remnant stomach to consist primarily of gastric type and secondarily of intestinal type cells, and ...
Spectrum of carcinoembryonic antigen immunoreactivity from isolated ductal hyperplasias to atypical hyperplasias associated with infiltrating ductal breast cancer
(British Med Journal Publ Group, 1995-01-01)
Aims - To study the immunohistochemical expression of carcinoembryonic antigen (CEA) in ductal hyperplasia of the breast and to investigate its putative relation with atypia and co-existing infiltrating ductal carcinoma.Methods ...
Sequence, evolution and ligand binding properties of mammalian Duffy antigen/receptor for chemokines
(Springer, 2004-01-01)
The Duffy antigen/receptor for chemokine, DARC, acts as a widely expressed promiscuous chemokine receptor and as the erythrocyte receptor for Plasmodium vivax. To gain insight into the evolution and structure/function ...
Interactions between TLR2, TLR4, and mannose receptors with gp43 from Paracoccidioides brasiliensis induce cytokine production by human monocytes
(Informa Healthcare, 2011-10-01)
The glycoprotein gp43 is an immunodominant antigen secreted by Paracoccidioides brasiliensis, the agent of paracoccidioidomycosis. The present study evaluated whether gp43 can interact with toll-like (TLR2, TLR4) and mannose ...
Detection of estrogen receptor in formalin-fixed and paraffin-embedded breast carcinoma: correlation with histological patterns.
(1992-07-01)
The authors studied the expression of estrogen receptor (ER) in tissues of breast carcinomas which were previously fixed in formalin and paraffin-embedded. The ER expression was correlated with several histological findings, ...
