BACKGROUD: Health care workers who are e-antigen-positive carriers of hepatitis B virus have become a significant focus of concern in the development of public health policy. In cases of needle-stick injury, the risk of transmission of HBV has been estimated at 60-fold greater if the carrier is positive for e antigen than if the carrier does not have the e antigen. Debate continues regarding pr...

Retinoic acid is known to cause the cell cycle arrest and myeloid differentiation of HL-60 myeloblastic leukemia cells. Evidence suggesting the possible involvement of the Fc RII immunoglobulin receptor in mediating retinoic acid-induced growth arrest and differentiation of HL-60 cells is presented. HL-60 cells stably transfected with the 205 mutant polyoma middle T antigen, a largely debilitat...

In this report we describe the production and characterization of a monoclonal antibody to the human promyelocytic leukemia cell line HL-60. The antibody, NC-2, is of the IgG1 subclass and precipitates a 50-Kd protein from 125I-labeled HL-60 cells. The antigen is insensitive to treatment with trypsin, papain, or neuraminidase. NC-2 did not react with a number of established human cell lines, in...

This study aimed at investigating the association between haemostatic biomarkers, proinflammatory, and anti-inflammatory cytokines with chronic kidney disease in type 1 diabetic patients. Patients were divided into two groups: with nephropathy (albuminuria ≥ 30 mg/g and/or GFR < 60 mL/min/1.73 m(2)), n = 65; and without nephropathy (albuminuria < 30 mg/g and GFR ≥ 60 mL/min/1.73 m(2)), n = 60. ...

We describe here coagglutination (Co-A), a rapid slide agglutination test for the detection of hydatid antigen in the urine for the diagnosis of cystic echinococcosis (CE). Paired urine and serum samples were collected from 16 patients with surgically confirmed CE, 10 patients with ultrasound-proven CE, 14 patients with clinically diagnosed CE, 24 patients with various parasitic diseases other ...

OBJECTIVE Colorectal cancer (CRC) is more common in developed countries and is the third most common cancer among both men and women. CRC provides an attractive model of tumour biology with normal mucosa to adenoma to carcinoma sequence. The TF-antigen (Thomsen-Friedenreich) can be identified by galactose oxidase-Schiff's (GOS) reaction either on tissues or on rectal mucus samples from patients...

the protective capacity of the crude extracts from larval and nymphal stages of hyalomma anatolicum anatolicum was examined in the new zealand white rabbits. the rabbits were randomly divided into 3 groups of five animals. the rabbits in groups 1 and 2 were immunized with crude extracts of larval and nymphal antigens, respectively and group 3 was served as control. following challenge of each r...

Background: Myelodysplastic syndrome is a mixed clonal disorder of bone marrow progenitor cells. Understanding the pattern of the different lineage-specific, immature, and mature markers in myelodysplastic syndrome will help in setting-up the frame of reference to diagnose. Patients and Methods: We compared 60 bone marrow samples from 30 newly-diagnosed patients with myelodysplastic syndrome ...
