Antagonistic relationships and genetic transformations. J.

with a positive constant λ. The equation Lu = 0 is then a second-degree elliptic equation. We also require the aij to be bounded and measurable, satisfying ‖aij‖L∞(B4) ≤ Λ with another constant Λ > 0. (In case you wonder, the radius ’4’ of the ball is to avoid fractions. Most of our estimates will be of the kind “some expression on B1 ≤ another expression on B4 ” and it would be unconvenient to...

In this paper, the gain spectrum and the saturation behavior of one-pump fiber optical parametric amplifiers (1-P FOPAs) are investigated by taking into account the fourth-order dispersion coefficient b4 in the analysis. The results show that it is necessary to consider b4 in the analysis when the wavelength difference between the signal and pump waves is large enough and/or whenever the pump w...

Anti-B4-blocked Ricin (Anti-B4-bR) is an immunotoxin comprised of the anti-B4 monoclonal antibody (MoAb) and the protein toxin "blocked ricin." The anti-B4 MoAb is directed against the B-lineage-restricted CD19 antigen expressed on more than 95% of normal and neoplastic B cells. Blocked ricin is an altered ricin derivative that has its nonspecific binding eliminated by chemically blocking the g...

Through synthesis and presentation of neuroendocrine self-antigens by major histocompatibility complex proteins, thymic epithelial cells (TECs) play a crucial role in programing central immune self-tolerance to neuroendocrine functions. Insulin-like growth factor-2 (IGF-2) is the dominant gene/polypeptide of the insulin family that is expressed in TECs from different animal species and humans. ...

It has been hypothesized that a disturbance of central self-tolerance to islet β cells may play a role in the enteroviral pathogenesis of type 1 diabetes. Whether enteroviruses can induce an impaired expression of β-cell self-antigens in thymic epithelial cells has been investigated in a murine thymic epithelial (MTE) cell line. This cell line was permissive to the diabetogenic group B4 coxsack...

The ability to reprogram in vivo a somatic cell after differentiation is quite limited. One of the most impressive examples of such a process is transdifferentiation of pigmented epithelial cells (PECs) to lens cells during lens regeneration in newts. However, very little is known of the molecular events that allow newt cells to transdifferentiate. Histone B4 is an oocyte-type linker histone th...

Some acetophenone derived bis Mannich bases (B1-B5) and piperidinols (C1, C4), which are the structural isomers of B1 and B4, and also quaternary piperidine derivative C6 were synthesized and studied for anticonvulsant activity. Of the compounds, C6 was reported for the first time. Chemical structures of the compounds were confirmed by UV, IR, 1H-NMR, 13C-NMR, mass spectra and elemental analysi...

Five human malignant non-T lymphoid cell lines have been established. THP-4 and THP-7 were derived from two children with common type acute lymphoblastic leukemia (ALL), THP-6 and THP-8 from two children with null cell type ALL and THP-9 from a child with malignant lymphoma. THP-4 was positive for cytoplasmic mu, B4, common ALL antigen (CALLA) and Ia-like antigen (Ia), THP-7 positive for B4, CA...
