Let m,n,s,k be four integers such that 3?s?n, 3?k?m and ms=nk. Set d=gcd?(s,k). In this paper we show how one can construct a Heffter array H(m,n;s,k) starting from square H(nk/d;d) whose elements belong to d consecutive diagonals. As an example of application method, prove there exists integer in each the following cases: (i) d?0(mod4); (ii) 5?d?1(mod4) nk?3(mod4); (iii) d?2(mod4) nk?0(mod4); ...

materials and methods in the present study, a potent nk-producing strain was isolated from cow milk and identified. to enhance the yield of nk, effect of various parameters such as ph, temperature, carbon source, nitrogen source and inoculum size were optimized. strain improvement of p. aeruginosa cmss was done by random uv-mutagenesis. nattokinase was partially purified and the activity was de...

Exosomes are released by various cells, including natural killer (NK) cells and transport signaling molecules for the intercellular communication. Hepatocellular carcinoma (HCC), also known as primary liver cancer, is often inoperable difficult to accurate diagnosis. Notably, prognosis underlying mechanisms of HCC not fully understood. Exosomes-derived NK (NK-exos) express unique cytotoxic prot...

The aim of this paper is a) if Σak2 < ∞ then Σak rk(x) is in BMO that{rk(x)} is Rademacher system. b) P1k=1 ak!nk (x) 2 BMO; 2k nk < 2k+1that f!n(x)g is Walsh system. c) If jakj < 1k then P1k=1 ak!k(x) 2 BMO.

conclusions our results suggested that cb-nk cells progenitors could proliferate and differentiate on feeder layer of amnion membrane mscs in combination with specific cytokines to produce nk cells for immunotherapy. results combination of cytokines and msc layer yielded significant fold expansion in comparison with cytokines without feeder conditions (day 7: 5.2 ± 1.12 and 2 ± 0.78, respective...
