The U. S. EPA is currently regulating emissions of HCl from hazardous waste incinerators under 40 CFH 264.343 to 4 lbs/hr or an HCl removal efficiency of at least 993. The EPA is also currently considering regulating HCl emissions from MWC’s. Several state and local agencies have already set HCl emission limits for new MWC's and are requiring installation of HCl EMS’s at certain facilities. Lab...

BACKGROUND Although use of long-acting opioid analgesics has increased for chronic nonmalignant pain management, little is known about patient-reported utilization patterns. OBJECTIVE To assess patient-reported utilization patterns of fentanyl transdermal system and oxycodone hydrochloride (HCl) controlled-release among patients with chronic nonmalignant pain and to compare these patterns to ...

Low-dose interferon-a (IFN-a) therapy is consistently effective in the treatment of hairy cell leukemia (HCL). In two cases of resistance to IFN-a administration, we diagnosed variant HCL, a form of HCL with intermediate features between typical HCL and B cell prolymphocytic leukemia. We tried to distinguish variant and typical hairy cells (HCs) by Northern blot analysis of the oncogenes expres...

Cells from hairy cell leukemia (HCL) and hairy cell leukemia variant (HCL-V) have a distinct immunophenotype which is of a mature but not terminally differentiated activated B-cell. Although some similarities exist between these two conditions like the expression of B-cell activation marker CD103, CD11c and IgG heavy chain expression, differences exists between these two diseases. HCL is positi...

Hairy cell leukemia (HCL) is an uncommon chronic lymphoproliferative disorder and accounts for around 2% of all forms of leukemias. The association of HCL with other neoplasms, mainly non-Hodgkin's lymphomas, is well known. However, the simultaneous diagnosis of HCL and Kaposi's sarcoma is rare, with only few cases of such an association having been reported. We describe a 42-year-old male pati...

Cycloprodigiosin hydrochloride (cPrG-HCl), a member of the prodigiosin family of compounds, has been reported to act as an H(+)/Cl(-) symporter. This compound induces apoptosis in several cancer cells and acts as an antitumor drug in animal models. In this study, we found a novel function of cPrG-HCl; to suppress cell death in PC12 cells, which is caused by protein synthesis inhibitors cyclohex...

Detection of the integrin subunit CD103 is a useful diagnostic tool in the diagnosis of hairy cell leukemia (HCL). Currently, flow cytometric analysis (FC) and frozen section immunohistochemistry (IHC) represent the only available methods of detection. This study is the first to describe the successful use of a CD103 antibody to identify HCL and HCL-variant in paraffin sections of formalin- or ...

Removal of MTA from dentin by applying 37% hydrochloric acid (HCl) to reduce microhardness and push-out bond strength. Forty dentin slices were filled with WMTA and divided into two groups (n = 20). Ten slices remained untreated while others were exposed to either HCl or phosphate buffer saline (PBS) and all samples were subjected to pushout test. The mode of bond failures was determined by SEM...

The presence of the BRAF c.1799T>A V600E mutation was recently described in cases of hairy cell leukemia (HCL) but not in other common lymphomas. However, many uncommon subtypes of lymphoma have not been studied. We designed a BRAF pyrosequencing assay specific for the V600E mutation, which has a sensitivity of 5% and is applicable to paraffin-embedded tissue. DNA was sequenced in 9 cases of HC...

To define cell surface antigens associated with hairy cell leukemia (HCL). and to gain better insight into the origin of this disease. we developed monoclonal antibodies against spleen cells of a patient with this disease. Although none of these antibodies alone proved specific for the leukemic cells. two of them. designated aS-HCL 1 (aLeu-14) and aS-HCL 3 (aLeu-M5) were found to be valuable in...
