Objective : The prognostic value of peripheral natural killer (pNK) cells, as a screening test in women with recurrent pregnancy loss (RPL) and unexplained infertility is still a matter for discussion. The aim of this study was to compare the percentage of circulating CD56+NK cells, CD69 and perforin markers between women with unexplained infertility and RPL with healthy control group. Material...

In the laboratory, an acaricide-susceptible strain of citrus red mite, Panonychus citri (McGregor) (LS-FJ), was used to screen for resistance spirotetramat. A spirotetramat-resistant (ST-NK) obtained after continuous selections through 15 selection cycles (45 generations) exhibited 1668.4-fold greater when compared parent generation. Instability spirotetramat in mites observed during 11 months ...

Antimicrobial peptides (AMPs) play an important role in innate immunity against pathogenic infections. AMPs exterminate bacteria by disrupting cell membranes or inhibiting intracellular molecules. NK-2, first identified pigs and derived from NK-lysin, has antimicrobial effects parasites. In this study, chimeric (cpNK) of chicken pig NK-2 cpNK-derived (cpNK-a1 cpNK-a2) were synthesized, their va...

background: mature t/ nk-cell neoplasms are a rare group of disorders and their presentation as leukemia is even rarer. most of the previous studies have focused on mature b-cell lineage leukemias and there is a paucity of data on mature t/nk-cell lineage leukemias. we, therefore, planned this study to analyze their spectrum, frequency, morphology and immunophenotypic features. methods: all cas...

hematopoietic cord blood (cb) stem cell transplantation has more advantages to other cell sources because of lower graft versus host disease (gvhd). interleukin-15(il-15) is an immunoregulatory cytokine, known to enhance cytolytic function of cord natural killer (nk) cells. the aim of this study was to investigate the effect of il-15 on nk cytotoxicity simultaneously in different cell death sta...

the number and function of human natural killer (nk) cells are generally assessed to monitor the baseline of immune function, the effect of treatment, the progress of malignancy or metastases and diseases. nk cells recognise and kill target cells in the absence of prior sensitisation and are able to defend the host from infection or prevent the progression of a disease. human nk cells express c...

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.

Detailed analysis of the natural killer (NK) activity directed at nontumorigenic cell lines and their transformed tumorigenic derivatives has revealed a paradox. On the one hand, a correlation has been found between the tumorigenic potential of chemically transformed fibroblast cell lines and their sensitivity to NK cells in vitro. Nontransformed cells (N-type cell lines) and cells tumorigenic ...

Natural killer (NK) cells are a promising tool for the use in adoptive immunotherapy, since they efficiently recognize and kill tumor cells. In this context, ex vivo cultivation is an attractive option to increase NK cells in numbers and to improve their antitumor potential prior to clinical applications. Consequently, various strategies to generate NK cells for adoptive immunotherapy have been...
