Circulating levels of the soluble interleukin 2 receptor (sIL-2R) could provide an in vivo measure of the immunologic response to human tumors. We performed a total of 326 sIL-2R serum assays in 126 patients with lung cancer (67 at diagnosis, 59 during and after treatment), 112 patients with pulmonary benign diseases, and 63 voluntary healthy subjects. Patients with lung cancer had a median val...
In this paper, we study the security of 2R− schemes [17, 18], which are the “minus variant” of two-round schemes. This variant consists in removing some of the n polynomials of the public key, and permits to thwart an attack described at Crypto’99 [25] against two-round schemes. Usually, the “minus variant” leads to a real strengthening of the considered schemes. We show here that this is actua...
Progression from infection with human papillomavirus (HPV) to cervical cancer in some women is thought to involve a permissive host environment, one in which immune response is mobilized in an inappropriate manner. In a previous study (A. Hildesheim et al., Cancer Epidemiol. Biomark. Prev., 6: 807-813, 1997), increasing levels of soluble interleukin 2 receptor (sIL-2R), a known proxy for genera...
The interleukin 2 receptor alpha-chain (IL-2R alpha) gene is a key regulator of lymphocyte proliferation. IL-2R alpha is rapidly and potently induced in T cells in response to mitogenic stimuli. Interleukin 2 (IL-2) stimulates IL-2R alpha. transcription, thereby amplifying expression of its own high-affinity receptor. IL-2R alpha transcription is at least in part controlled by two positive regu...
BACKGROUND Even after adequate immunosuppression therapy, acute rejection continues to be the single most important cause of graft dysfunction after renal transplantation. Renal allograft biopsy continues to be the reference standard, though certain clinical and biochemical parameters are helpful in assessment of these patients. Renal allograft rejection is mediated by T lymphocytes, expressing...
This paper presents a resistance matching based selftestable current-mode R-2R Digital-to-Analog Converter (DAC). The Built-In Self-Test (BIST) circuits are employed to observe the current redistributions in the resistance matching branches converted from the R-2R network in the DAC, and then the redistributed currents are transformed to voltages to detect the R-2R network with extra Design For...
In two patients with primary bone lymphoma (PBL) treated in our clinic, serum levels of soluble interleukin-2 receptor (sIL-2R) reflected the clinical course. In both cases, sIL-2R levels were high before treatment and normalized with the therapeutic effects of chemotherapy, coinciding with the changes in lactate dehydrogenase levels and radiographic findings. Adding to the recently reported re...
Activated soluble IL-2 receptor (sIL-2R) levels are elevated in a variety of diseases associated with T-cell activation. There are no reports of sIL-2R elevations in broncholitis obliterans organizing pneumonia/cryptogenic organizing pneumonia (BOOP/COP), although activated T cells are increased in BOOP/COP. We present a patient with BOOP/COP with an elevated concentration of soluble IL-2 recep...
A patient with allergic granulomatous angiitis accompanied by increases in serum interleukin-2 receptor (IL-2R) and interferon-alpha (IFN-alpha) levels is reported. Laboratory findings revealed leukocytosis with eosinophilia and increased serum IgE and IgG. The serum IL-2R and IFN-alpha were increased. The serum immune complex, interferon-beta, -gamma and complements remained at normal levels. ...
Melanin-concentrating hormone (MCH) is a 19-aa cyclic neuropeptide originally isolated from chum salmon pituitaries. Besides its effects on the aggregation of melanophores in fish several lines of evidence suggest that in mammals MCH functions as a regulator of energy homeostasis. Recently, several groups reported the identification of an orphan G protein-coupled receptor as a receptor for MCH ...
