The IL-7R alpha-chain and the common gamma-chain (gamma(c)) are both components of IL-7R. Human plasma harbors soluble forms of IL-7R (sIL-7Ralpha and sgamma(c)) that are detected and assayed by Western blotting, showing that the levels of sIL-7Ralpha are higher than the levels of sgamma(c) (47.5 ng/ml and 1.5 ng/ml, respectively). Gel electrophoresis and tandem mass spectrometry used to analyz...

BACKGROUND The purpose of this study was to determine the prevalence and risk factors for cervical squamous intraepithelial lesions (SIL) among women infected with human immunodeficiency virus type 1 (HIV-1) receiving care at the Federal Medical Center Makurdi, Nigeria. METHODS Between March and December 2009, a total of 253 women infected with HIV-1 had cervical smears taken for cytology. HI...

OBJECTIVE The present study was conducted to investigate whether the serum levels of interleukin 6 (IL-6), soluble IL-2 receptor (sIL-2R) and sIL-6R are associated with the morphological appearance of rheumatoid arthritis (RA). METHODS Using the ELISA technique we measured the IL-6, sIL-2R and sIL-6R concentrations in the serum of 34 patients with RA and 28 patients with osteoarthritis (OA). ...

Hepatocellular carcinoma (HCC) is a global health burden that is associated with limited treatment options and poor patient prognoses. Silybin (SIL), an antioxidant derived from the milk thistle plant (Silybum marianum), has been reported to exert hepatoprotective and antitumorigenic effects both in vitro and in vivo. While SIL has been shown to have potent antitumor activity against various ty...

Interleukin (IL)-15 associates with IL-15Rα on the cell surface where it can be cleaved into soluble cytokine/receptor complexes that have the potential to stimulate CD8 T cells and NK cells. Unfortunately, little is known about the in vivo production of soluble IL-15Rα/IL-15 complexes (sIL-15 complexes), particularly regarding the circumstances that induce them and the mechanisms responsible. ...

Ballistic-electron-emission microscopy (BEEM) is used to probe local conduction-band structure in strained Sil .xGq layers of pseudomorphic Sil-xGe#Si heterostmctires. The strain variation produced by a roughened Si l.xGex surface is seen as a variation of splitting between thresholds in BEEM spectroscopy. This splitting is directly related to the strain-induced conduction-band splitting in the...

AIM Effects of homeopathic treatment with Hypericum perforatum (Hypericum) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. METHODS Fifty-four male healthy White Wistar rats were divided into three experimental groups (n = 18), randomly: Sham-operation (Sham), control: silicon tube (Sil) and treatment: silicon tube + Hypericum (Sil/Hypericum). In the S...

BACKGROUND Soluble cytokine receptors and receptor antagonist of proinflammatory cytokines can modify cytokine signaling and may affect cancer risk. METHODS In a case-cohort study nested within the Women's Health Initiative cohort of postmenopausal women, we assessed the associations of plasma levels of interleukin (IL)-1 receptor antagonist (IL-1Ra) and the soluble receptors of IL-1 (sIL-1R2...

Serum concentrations of soluble interleukin 2 receptors (sIL 2R) were measured by an enzyme-linked immunosorbent assay (ELISA) in 30 patients with adult T cell leukemia (ATL), in 9 patients with other hematopoietic malignancies, and in 17 asymptomatic individuals seropositive for human T cell leukemia virus type I (HTLV-I). Sixty HTLV-I seronegative, age-matched controls showed a normal range o...

We have expressed a soluble N-glycosylated form of the murine interleukin-11 (IL-11) receptor alpha-chain (sIL-11R) and examined signaling in cells expressing the gp130 molecule. In the presence of gp130 but not the transmembrane IL-11R, the sIL-11R mediated IL-11-dependent differentiation of M1 leukemic cells and proliferation in Ba/F3 cells. Early intracellular events stimulated by the sIL-11...
