acute myeloblastic leukemia is the most frequent cancer in adults and the patients have a wide range of sub-classes. hla dr negative cases represent one of the major immune-phenotypic classes.  hla-dr is routinely used to distinguish acute promyelocytic leukemia (apl) from other aml subclasses based on the immunophenotype. the tgf-b signaling pathway, as a critical regulator, guides different v...

Absent or diminished HLA-Dr antigen representation on the cell surface of both normal and leukemic promyelocytes is a hallmark of this stage of myeloid maturation. In order to document the specificity of this finding for acute promyelocytic leukemia, flow cytometric analysis of leukemic blasts was utilized on 36 cases of acute non-lymphocytic leukemia. All 15 of the promyelocytic leukemias (FAB...

Expression of cell surface molecules associated with lymphoid and myeloid lineage differentiation on the blasts of 53 patients with acute lymphoblastic leukemia (ALL) was investigated. 1.9% of cases were only HLA"7DR+ 7.6% were HLA-DR+, CDI9+ 22.6% were HLA-DR+, CDI9+, CDI0+ 30.2% were HLADR+, CDI9+, CDlO±, CD20+ and 37.7% were HLA-DR±, CD7+, CD5±. Aberrant expression of one or more myeloi...

We have measured the competitive antagonistic effect of chlorpheniramine in bronchi of 8 normal and 12 asthmatic subjects. Classical pharmacological theory states that the degree of competitive antagonism depends only upon 1) antagonist concentration at the receptor, and 2) receptor affinity. Delivery and affinity also influence agonist responsiveness, but measurement of bronchial antagoni...

The aim of our study was to evaluate the diagnosis of desmoplastic reaction (DR) by immunostaining for α-smooth muscle actin (αSMA) and desmin, for predicting the depth of submucosal invasion in biopsy specimens of early colorectal carcinomas (CRCs). Thirty-eight cases of non-pedunculated early CRCs were included in this study. Positive for DR was defined as αSMA-positive and desmin-negative st...

The characteristics of antigen-presenting cells in carcinomas that involve the abdominopelvic cavity are unknown. Dendritic cells, a population of antigen-presenting cells, have been identified as lineage-negative human leukocyte antigen (HLA)-DR+ cells by two-color flow cytometry. We used this criterion to study the putative dendritic cells in ascites from 25 patients with peritoneal carcinoma...

In order to assess the relation between diabetic iridopathy (DI) and retinopathy (DR), 225 eyes of 117 diabetics with clear media were evaluated. Each patient underwent iris and retinal fluorescein angiography, which was used to classify DI and DR. DI was classified as: absence of DI; non-proliferative DI; proliferative DI; neovascular glaucoma. DR was classified as: absence of DR; background D...

This paper describes the concept for and lessons from the development and field-testing of an open, interoperable communications infrastructure to support automating demand response (DR). Automating DR allows greater levels of participation and improved reliability and repeatability of the demand response and customer facilities. Automated DR systems have been deployed for critical peak pricing...
