Definition Peptide nucleic acid (PNA) is an artificial mimic of nucleic acid, which was invented more than a decade ago (7). The molecule combines many features that are similar to those of natural nucleic acids with characteristics that are rather different or even unique to PNA. First and foremost, N-(2-aminoethyl)-glycine units linked by ▶amide bonds substitute the (deoxy)ribosephosphate bac...

This paper presents a longitudinal case study in UK biotechnology covering some 30 years during which genomic technologies were introduced into pig breeding. demonstrates how co-innovation involving existing small and medium sized enterprises, together with contributions from academics, has enabled companies to obtain the resources needed for value creation. Important at critical junctures publ...

introduction low dose rate brachytherapy sources have been widely used for interstitial implants in tumor sites, particularly in prostate. dosimetric characteristics of a new irseed 125i brachytherapy source have been determined using the lif thermoluminescent dosimeter (tld) chips. materials and methods dose rate constant, radial dose function, and anisotropy function around the irseed 125i so...
