Abstract The polycaprolactone diol (PCL diol) was prepared by ring-opening polymerization method, with hydroquinone bis(2-hydroxyethyl) ether as the reactive initiator and ε-caprolactone monomer. polyurethane acrylate (PUA) self-made PCL diol. Then, PUA used to prepare ultraviolet curable coatings. structure molecular weight of characterized Fourier transform infrared spectroscopy, gel-permeati...

The relation between the factor systems of a group and the factor systems of an invariant subgroup is discussed both for PU and for PUA representations. The results are used to discuss the factor systems of a class of magnetic space groups.

Objective The prevalence of benign prostatic hyperplasia (BPH) rapidly increases after the 4th decade of life. The combination of tamsulosin and dutasteride is a well established therapy for BPH of ≥40 g. Non-invasive urodynamic parameters can predict the outcome of medical therapy in patients with BPH. We aimed to correlate these parameters with treatment responses in BPH patients under medica...

introduction: the penetration depth of irrigating solutions in dentinal tubules is limited; consequently, bacteria can remain inside dentinal tubules after the cleaning and shaping of the root canal system. therefore, new irrigation systems are required to increase the penetration depth of irrigating solutions in dentinal tubules. methods: a comparative study regarding the penetration depth of ...

We report the case of a 40-year-old male patient with dyskeratosis congenita(DKC). Sequencing of the DKC1 gene revealed an inherited missense mutation in base 1050 (GC), changing methionine to isoleucine. This is the third description of a mutation in codon 350 (exon 11), changing a very well conserved amino acid in the pseudouridine synthase (PUA) domain of dyskerin.

Ethylene, a gaseous plant hormone, is involved in regulation of various physiological responses during plant growth and development. These include seed germination, abscission, fruit ripening, and plant senescence (Yang and Hoffman, 1984). Plants also produce high levels of ethylene when they are under environmental stresses or pathogen attacks. In ethylene biosynthesis, the precursor Met is co...
