Background: The critical role of interleukin-7 (IL-7) in homeostatic proliferation and T cell survival has made it a promising cytokine for the treatment of various clinical conditions, especially those associated with lymphopenia. Methods: In the present study we expressed recombinant human interleukin-7 (rhIL-7) in Chinese hamster ovary (CHO)-K1 cells. CHO-K1 cells were stably transfected ...

This paper presents an analysis and control of chaos in the boost converter controlled with zero average dynamics, fixed-point induced control, time-delayed autosynchronization techniques. First, existence is demonstrated numerically when positive Lyapunov exponents are found system, for a range from k1=−0.26 to k1=0.4387, k2=0.5. Additionally, also k1=−0.435 k1=0.26, k2=−0.5. Subsequently, fix...

In this work, we investigated the mixing between strange axial vector mesons K1(1270) and K1(1400) by using QCD Sum Rules approach. Since these states couple to same interpolating currents, defined them in terms of orbital angular momentum eigen K1A K1B. By tensor currents which are almost purely coupling K1B, then employing orthogonality physical states, obtained an analytical expression for K...

The severe adverse reaction to vitamin K1 injection is always remarkable and is thought to result from anaphylaxis. Paradoxically, however, some patients administered vitamin K1 injection for the first time have adverse reactions. Using beagle dogs, the present study tested the hypothesis that the response to vitamin K1 is an anaphylactoid reaction. The results showed that serious anaphylaxis-l...

Escherichia coli (E. coli) K1 sepsis and meningitis is a severe infection characterized by high mortality in neonates. Successful colonization and translocation across the intestinal mucosa have been regarded as the critical steps for E. coli K1 sepsis and meningitis. We recently reported that the probiotic mixture, Golden Bifido (containing live Lactobacillus bulgaricus, Bifidobacterium, and S...

Expression of the K1 gene of human herpesvirus 8 activates nuclear factorB and induces lymph node hyperplasia and lymphomas in transgenic mice. To further delineate its role in cell survival, we determined whether K1 altered apoptosis of lymphoma cells. K1 protein is expressed in Kaposi sarcoma and primary effusion lymphoma. We retrovirally transfected BJAB lymphoma, THP-1, U937, and Kaposi sar...
