Membrane filtration technology has attracted extensive attention in academia and industry due to its advantages of eco-friendliness related environmental protection high efficiency. Polyamide thin-film composite nanofiltration (PA TFC NF) membranes have been widely used their separation performance. Non-acid-resistant PA NF face tremendous challenges an acidic environment. Novel relatively acid...
Pyrrole-imidazole polyamides are a class of small molecules that can be programmed to bind a broad repertoire of DNA sequences, disrupt transcription factor-DNA interfaces, and modulate gene expression pathways in cell culture experiments. In this paper we describe a high-resolution X-ray crystal structure of a β-amino turn-linked eight-ring cyclic Py-Im polyamide bound to the central six base ...
Three DNA binding polyamides () were synthesized that bind with high affinity (K(a) = 8.7. 10(9) m(-1) to 1.4. 10(10) m(-1)) to two 7-base pair sequences overlapping the Ets DNA binding site (EBS; GAGGAA) within the regulatory region of the HER2/neu proximal promoter. As measured by electrophoretic mobility shift assay, polyamides binding to flanking elements upstream () or downstream (2 and 3)...
The use of urinary and/or biliary excretion data was considered as an alternative approach if the bioanalytical method lacked the appropriate sensitivity to adequately characterize the serum or plasma concentration-time profile. This approach is used for the analysis of plasma concentration-time profile under the lower limit of quantification (LLOQ) of various analytical instruments. The object...
Mirroring of missing facial parts and rapid prototyping of templates have become widely used in the manufacture of prostheses. However, mirroring is not applicable for central facial defects, and the manufacture of a template still requires labour-intensive transformation into the final facial prosthesis. We have explored innovative techniques to meet these remaining challenges. We used a morph...
