background & objectives: antisense peptide nucleic acids (pna) that target growth essential genes show potent bactericidal properties without cell lysis. we considered the possibility that whether pna treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to dendritic cells (dcs). dcs are the most potent antigen presenting cells in t...

• Experiment and kinetic modeling of Passive NOx adsorption (PNA) over Pd/SSZ-13. A model was developed for PNA performance different operating conditions. detailed mechanism the roles CO in passive NO x has been derived. thermal converter to assess real-life recently as a promising technology controlling emissions during cold start period. In this work, we illustrate CO-assisted by combining e...

J 248 nm.The quantum yield for production of OH radicals is 34 f li%g The I yield of OH from PNA was measured relative to that from H202. The translational and rotational energy content of the OH photofragment from PNA has been characterized. A fluorescent emission was also observed and characteriz...

introduction: the cell surface glycoconjugate and extracellular matrix may mediate extracellular signals which decide the fate of the cells during tissue interactions. the proper development of cornea needs cellular interaction between surface epithelium, neural crest and developing lens. materials and methods: 50 pregnant rats were chosen and the embryos from pernatal day11-to 20 and postnatal...

BACKGROUND The protein equivalent of total nitrogen appearance (PNA) is assumed to be a reliable estimate of dietary protein intake in haemodialysis patients. Protein requirements are related to body size. In order to standardize PNA to individual differences in body size, PNA is normalized to various terms related to the patient's body weight. It is not clear which is the most appropriate meth...

A magnetic cell separation technique (MACS) was developed for isolating and characterizing peanut lectin agglutinin positive (PNA(+)) cells from rainbow trout gills. Percoll density separated mitochondria-rich (MR) cells were serially labeled with PNA-FITC and an anti-FITC antibody covalently coupled to a 50-nm iron particle and then applied to a magnetic column. PNA(+) MR cells were enriched t...

An endo-acting proline-specific oligopeptidase (prolyl oligopeptidase [POPase], EC 3.4.21.26) was purified to homogeneity from the Triton X-100 extracts of cells of Treponema denticola ATCC 35405 (a human oral spirochete) by a procedure that comprised five successive fast protein liquid chromatography steps. The POPase is a cell-associated 75- to 77-kDa protein with an isoelectric point of ca. ...
