Aldehyde oxidase (AO) plays an important role in metabolizing antitumor and antiviral drugs, including methotrexate, cyclophosphamide and acyclovir. Green tea and its catechins have been shown to modulate the activities of various xenobiotic-metabolizing cytochrome P450 species, both in vivo and in vitro, but their effect on AO has not been studied. Therefore, we evaluated the effect of tea bev...

The age of onset (AO) of hereditary ATTR amyloidosis (hATTR) is known to vary between populations, with differing characteristics reported according to AO in endemic/non-endemic foci. This was a retrospective study of patients with early AO (<50 years) and late AO (≥50 years) hATTR at our center in Mallorca. Data were collected on patient demographics, clinical disease manifestation, and physic...

Over the last 20 years, the topics of action observation (AO) and motor imagery (MI) have been largely studied in isolation from each other, despite the early integrative account by Jeannerod (1994, 2001). Recent neuroimaging studies demonstrate enhanced cortical activity when AO and MI are performed concurrently ("AO+MI"), compared to either AO or MI performed in isolation. These results indic...

purpose: to compare acrysof iq and akreos ao aspheric intraocular lenses (iols) in terms of spherical aberration and contrast sensitivity. methods: thirty-seven eyes of 37 patients undergoing phacoemulsification cataract surgery were randomized to implantation of acrysof iq or akreos ao iols. three months postoperatively, best-corrected visual acuity (bcva), spherical aberration (with 4 and 6 m...

We report on the rerouting of peroxisomal alcohol oxidase (AO) to the secretory pathway of Hansenula polymorpha. Using the leader sequence of the Saccharomyces cerevisiae mating factor alpha (MFalpha) as sorting signal, AO was correctly sorted to the endoplasmic reticulum (ER), which strongly proliferated in these cells. The MFalpha presequence, but not the prosequence, was cleaved from the pro...

Acridine orange (AO) was extracted as a dye from coal tar over a hundred years ago. It has various unique biological activities and has been shown to be a useful fluorescent dye specific for DNA and RNA, a pH indicator, photosensitizer, antitumor and antimalarial drug, and detector of bacteria and parasites. It has recently been found that AO accumulates in musculoskeletal sarcomas and that aft...
