Objectives: To assess the level of nutritional knowledge (NK) among male Kuwaiti college students and to correlate NK scores with different nutritional domains. Methods: A random sample of 378 students was asked to answer a questionnaire regarding socio-demographic and health-related factors and answer questions assessing their NK on different domains. Height and weight were measured. Results: ...

Background Natural killer (NK) cells are immune that can detect and eliminate tumor bridge innate to adaptive responses. Tumor specific activation of NK is thus an area active investigation in oncology, but date has relied on complex biologic modalities (e.g., antibodies, fusion proteins, or cell therapies), each which inherent disadvantages this application. Thus, alternative approaches warran...

PURPOSE Renal cell carcinoma harbors high numbers of infiltrating lymphocytes with apparent limited efficacy in tumor control. This study focused on the natural killer (NK) cells infiltrating renal cell carcinoma. EXPERIMENTAL DESIGN Tumor-infiltrating lymphocytes (TIL) were isolated from renal cell carcinoma and analyzed for NK cell frequency and phenotype (n = 34). NK cells were enriched an...

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...

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...
