methods the current study generated two recombinant lentiviruses, plex-gcn and plex-gcp, bearing noxa and puma, respectively. transduction of both genes to hepatocarcinoma (hepg2) was verified using fluorescent microscopic analysis, western blotting, and quantitative real-time polymerase chain reaction (pcr). to evaluate the potential of noxa and puma to initiate apoptosis, a caspase-9 real-tim...

background: alteration in peripheral blood lymphocytes (pbls) is usually investigated to provide an evidence of the host immune responses to tumor antigens. the tumor infiltrating nk cells interact most closely with the tumor cells and more accurately reflect tumor host interactions. objective: to analyze peripheral blood and tumor associated natural killer (nk) cells in patients with breast ca...

Decidual natural killer cells accumulate at the fetal-maternal interface and play a key role in a successful pregnancy. However, their origin is still unknown. Do they derive from peripheral natural killer cells recruited in decidua or do they represent a distinct population that originates in situ? Here, we identified natural killer precursors in decidua and uterus of pregnant mice. These prec...

Precision Drug Delivery In article number 2206989, Yu Tao, Mingqiang Li, Xuesi Chen, and co-workers report a membrane-fusogenic liposome to precisely convey two glycan-engineering drugs onto the cell membrane into cytoplasm for physical modification of natural-killer-cell-activating glycans biological inhibition immunosuppressing glycans, respectively, thus sufficiently arousing natural killer ...

In this paper we describe a real-time speech recognition system developed for colloquial Iraqi Arabic. This system is currently used in our speech-to-speech translation system configured for bi-directional communication in English and Iraqi on a laptop. We present experimental results on Iraqi utterances from different speech-to-speech translation domains, and analyze the usefulness of acoustic...

The Escherichia coli beta-glucuronidase gene has been used as a marker gene to monitor a killer Saccharomyces cerevisiae strain in mixed-culture ferments. The marked killer strain was cured of its M-dsRNA genome to enable direct assessment of the efficiency of killer toxin under fermentation conditions. Killer activity was clearly evident in fermenting Rhine Riesling grape juice of pH 3.1 at 18...

In normal human peripheral blood, cutaneous lymphocyte antigen is expressed by memory T cells, suggesting a specific tissue-homing population of T cells. In this study it is demonstrated that 6% of CD56 + natural killer cells in peripheral blood also express cutaneous lymphocyte antigen (CLA). It was also detected that most of the tumor cells in primary cutaneous nasal-type natural killer cell ...

Natural killer cells are well known to mediate anti-leukemic responses in myeloid leukemia but their role in myelodysplastic syndromes is not well understood. Here, in a cohort of newly diagnosed patients (n=75), widespread structural and functional natural killer cell defects were identified. One subgroup of patients (13%) had a selective deficiency of peripheral natural killer cells (count <1...
