The Moderate Resolution Imaging Spectroradiometer (MODIS) provides daily global coverage, but the 10 km resolution of its aerosol optical depth (AOD) product is not suitable for studying spatial variability of aerosols in urban areas. Recently, a new Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm was developed for MODIS which provides AOD at 1 km resolution. Using MAIAC ...

Acute aortic dissection (AoD) affects approximately 2000 people per year in the United States.1 The International Registry of Aortic Dissection (IRAD),2 the largest multinational registry of patients with AoD, reports that only 7% of patients with AoD are younger than 40 years of age, a factor that might not prompt a raised index of suspicion among clinicians caring for younger individuals pres...

BACKGROUND There is a widely held expectation that GPs will routinely use opportunities to provide opportunistic screening and brief intervention for alcohol and other drug (AOD) abuse, a major cause of preventable death and morbidity. AIM To explore how opportunities arise for AOD discussion in GP consultations and how that advice is delivered. DESIGN Analysis of video-recorded primary car...

BACKGROUND There are several known factors that cause ischemic heart disease. However, the part played by air pollution still remains something of a mystery. Recent attention has focused on the chronic effect of particulate matter on heart disease. Satellite-derived aerosol optical depth (AOD) was found to be correlated with PM2.5 in the eastern US. The objective of this study was to examine if...

The diagnosis of traumatic atlantooccipital dislocation (AOD) from the cross-table lateral radiograph is difficult because of problems in demonstrating the complex anatomy of this area and the intricate radiographic methods used to diagnose AOD. Although CT or polytomography seem to be the most accurate diagnostic methods, it is often the lateral radiograph from which the diagnosis and further ...

A model of neonatal autoimmune disease has been described recently in which an epitope-specific autoantibody to murine zona pellucida 3 induces severe ovarian disease in neonatal, but not adult, mice (neonatal AOD). The autoantibody forms immune complex with endogenous ovarian zona pellucida 3, and a pathogenic CD4(+) T cell response is triggered. The basis for the predominant neonatal suscepti...

BACKGROUND This study aimed to measure the serum soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and interleukin-17A (IL-17A) levels in hypertensive patients with/without asymptomatic organ damage (AOD), as well as to determine the relationship between the serum sTWEAK and IL17-A levels, and carotid intima media thickness (CIMT), proteinuria, retinopathy, and the left vent...

Screening for alcohol and other drug (AOD) use followed by brief intervention (SBI) represents a useful tool for health professionals, since most people who are in the early stages of substance-related problems receive no guidance before developing significant consequences. In order to disseminate the techniques of SBI among Brazilian health professionals, the National Secretary on Drug Policy ...

BACKGROUND The use of alcohol and other drugs (AODs) in the workplace has a major impact on the health and productivity of the workforce globally. Yet information on this issue is limited in South Africa (SA). OBJECTIVE To describe the nature and extent of AOD problems in selected workplace settings in SA. METHODS Secondary data analysis was conducted on a large dataset compiled by an Emplo...

This study explores performance requirements for the retrieval of the atmospheric aerosol optical depth (AOD) by airborne optical remote sensing instruments. Independent of any retrieval techniques, the calculated AOD retrieval requirements are compared with the expected performance parameters of the upcoming hyperspectral sensor APEX at the reference wavelength of 550nm. The AOD accuracy requi...
