The murine pre-B leukemic cell line 70Z/3 contains both an unrearranged immunoglobulin kappa-light-chain gene and a functionally rearranged but silent kappa-light-chain gene. Mitogenic stimulation of growing 70Z/3 cells with bacterial lipopolysaccharide (LPS) activates kappa-light-gene transcription and results in a 10- to 20-fold increase in cytoplasmic kappa-light-chain mRNA. The induction of...

AIM To investigate the activation of nuclear factor-kappa B (NF-kappa B) and its function in glucocorticoid-induced Leydig cell apoptosis. METHODS The Leydig cells were isolated from male Sprague-Dawley rats (90 days of age) and were incubated with corticosterone (CORT, glucocorticoid in rat) for 6 h, 12 h and 24 h, respectively. The P65 subunit of NF-kappa B (NF-kappa B/P65) in nuclei and th...

Accurate constraints on curvature provide a powerful probe of inflation. However, based specific assumptions dark energy may lead to unreliable conclusions when used test inflation models. To avoid this, it is important obtain that are independent for energy. In this paper, we investigate such from the geometrical constructed galaxy-lensing cross-correlations. We study comprehensively cross-cor...

In this paper, by applying Mahgoub transform, we show that the \(n^{\rm th}\) order linear differential equation \[x^{(n)}(v)+\sum_{\kappa=0}^{n-1}a_\kappa x^{(\kappa)}(v)=\psi(v)\] has Hyers-Ulam stability, where \(a_\kappa\)'s are scalars and \(x\) is an \(n\) times continuously differentiable function of exponential order.

A monoclonal antibody (K-1-21) raised against a kappa Bence Jones protein exhibits unique binding properties to malignant plasma cells. K-1-21 is an IgG1 kappa antibody that reacts with human kappa light chains in free form, but shows no reactivity with heavy chain-associated kappa light chains. By immunofluorescence, K-1-21 binds to the surface of LICR LON/HMy2 (HMy2) kappa myeloma cells and t...

DNA polymerase kappa (Pol kappa) is a newly identified low-fidelity polymerase implicated in spontaneous and DNA damage-induced mutagenesis. As an initial study to investigate its possible involvement in tumorigenesis, we compared the expression level of Pol kappa in tumors and adjacent nontumorous tissues by Northern blot, semiquantitative RT-PCR, and Western blot analyses. In this study, pair...

Commutator methods are applied to get limiting absorption principles for the discrete standard and Molchanov-Vainberg Schr\"odinger operators $H_{\mathrm{std}}= \Delta+V$ $H_{\mathrm{MV}} = D+V$ on $\ell^2(\mathbb{Z}^d)$, with emphasis $d=1,2,3$. Considered electric potentials $V$ satisfying a long range condition of type: $V-\tau_j ^{\kappa}V$ decays appropriately some $\kappa \in \mathbb{N}$ ...
