We study the quality of the SCIAMACHY Absorbing Aerosol Index (AAI) product developed at our institutes. The AAI in general is determined from the reflectance at two wavelengths in the UV, and is highly sensitive to errors in the absolute radiometric calibration. We apply a degradation correction to the level-1 reflectance and test the temporal behaviour of the resulting AAI data. This we do by...

UNLABELLED Aristolochic acid I (AAI) is a plant drug found in Aristolochia species that causes aristolochic acid nephropathy, Balkan endemic nephropathy and their associated urothelial malignancies. AAI is activated via nitroreduction producing genotoxic N-hydroxyaristolactam, which forms DNA adducts. The major enzymes responsible for the reductive bioactivation of AAI are NAD(P)H quinone oxi...

This study aims to develop and validate a strength-based instrument for assessing the academic advising needs of university students in Hong Kong using Appreciative Advising Inventory (AAI) as blueprint. We reviewed content validity cultural relevance AAI developed 37-item Version (AAI-HK). conducted Rasch analysis principal component analysis. The AAI-HK has four stable reliable factors (socia...

Exposure to aristolochic acid I (AAI) can lead to aristolochic acid nephropathy (AAN), Balkan endemic nephropathy (BEN) and urothelial cancer. The induction of hepatic CYP1A, especially CYP1A2, was considered to detoxify AAI so as to reduce its nephrotoxicity. We previously found that baicalin had the strong ability to induce CYP1A2 expression; therefore in this study, we examined the effects o...

Authentication and Authorization Infrastructures (AAIs) are single sign-on systems. Their purpose is authenticating a user once, i.e. locally at the user’s so-called home organization, and then checking authorization of requested resource accesses based on user attributes the user’s home organization delivers. AAIs are just about being widely employed, and Switzerland is playing a pioneering ro...

The auditory evoked potential (AEP) is correlated to anaesthetic depth. The AEP has been used in rats, pigs, dogs and humans to assess anaesthetic depth. This study was undertaken to determine whether the AAI Index derived from the AEP correlated with changes in end tidal isoflurane concentration in dogs. The average AAI Index was 21.8 +/- 10.5 and isoflurane concentration was 1.7 +/- 0.4%. Dat...

BACKGROUND Reduced ankle-arm index (AAI), inflammation and mineral bone disorder (MBD) are all associated with increased risk of death and cardiovascular complications in patients on hemodialysis (HD), but the association between them deserves clarification. OBJECTIVE To evaluate the association between abnormal AAI with MBD and inflammation in patients on HD. METHODS This was a cross-secti...

BACKGROUND Stanford Type B acute aortic dissection (TB-AAD) spares the ascending aorta and is optimally managed with medical therapy in the absence of complications. However, the treatment of TB-AAD with aortic arch involvement (AAI) remains an unresolved issue. METHODS AND RESULTS We examined 498 patients with TB-AAD enrolled in the International Registry of Acute Aortic Dissection (IRAD) be...

BACKGROUND A low ankle-arm index (AAI) is a strong predictor of mortality and cardiovascular events. A high AAI also appears to be associated with higher mortality risk in select populations. However, mortality and cardiovascular risk across the AAI spectrum have not been described in a more broadly defined population. METHODS AND RESULTS We examined total and cardiovascular mortality and car...
