A fractional advection-dispersion equation (ADE) is a generalization of the classical ADE in which the second-order derivative is replaced with a fractional-order derivative. In contrast to the classical ADE, the fractional ADE has solutions that resemble the highly skewed and heavy-tailed breakthrough curves observed in field and laboratory studies. These solutions, known as alpha-stable distr...

The goal of pharmacovigilance is to detect, monitor, characterize and prevent adverse drug events (ADEs) with pharmaceutical products. This article is a comprehensive structured review of recent advances in applying natural language processing (NLP) to electronic health record (EHR) narratives for pharmacovigilance. We review methods of varying complexity and problem focus, summarize the curren...

This paper reviews extant agent applications and describes the Agent Development Environment (ADE) toolkit. ADE is the integrated development environment to design, develop, debug, simulate and deploy agents. ADE supports the development of multi-agent applications capable of running on a single machine or on a distributed network. ADE has been used to build commercial applications in the area ...

Adverse drug events (ADEs) are unintended responses to medical treatment. They can greatly affect a patient's quality of life and present a substantial burden on healthcare. Although Electronic health records (EHRs) document a wealth of information relating to ADEs, they are frequently stored in the unstructured or semi-structured free-text narrative requiring Natural Language Processing (NLP) ...

Atopic dermatitis (AD), with the prevalence rate of around 10 to 15%, is characterized by an intensely pruritic skin lesions with typical distribution and morphology. Recently, AD is divided into extrinsic type (ADe) and intrinsic type (ADi) according to the laboratory findings and associated diseases. ADe is well-known for high IgE level, positive response to food- or aero-allergens, whereas A...

This study describes coping strategies that patients with heart failure (HF) use to manage adverse drug events (ADEs). The included coping strategies were social support seeking, information seeking, non-adherence and taking alleviating medication. The role of beliefs about medication and ADE perceptions in explaining these coping strategies was assessed using the Self-Regulation Model. We perf...

S-Adenosylhomocysteine (AdoHcy) hydrolase is irreversibly inactivated by (E)-5',6'-didehydro-6'-deoxy-6'-halohomoadenosines (EDDHHAs, halogen = I, Br, and Cl). The inactivation is concomitant with the reduction of the enzyme-bound NAD+ (E.NAD+) to NADH, the release of halide ion, and the formation of adenine (Ade) from the EDDHHAs. The mechanism of this inactivation involves two catalytic pathw...

BACKGROUND The root of Angelica dahurica Bentham et Hooker (Umbelliferae) has been used as a traditional medicine for colds, headache, dizziness, toothache, supraorbital pain, nasal congestion, acne, ulcer, carbuncle, and rheumatism in China, Japan, and Korea. Interestingly, it has been used in the treatment of vascular diseases including hypertension. The aim of this study was to provide pharm...

This paper describes the collaboration of Brigham and Women’s Hospital and Regenstrief Institute to develop a computerized adverse drug event (ADE) monitor using electronic medical records from outpatient practices. We describe the steps involved in ADE monitor development and rule validation at large outpatient practices at Boston and Indianapolis. The final standard rule set adopted by both p...

BACKGROUND AND OBJECTIVES Outpatient adverse drug events (ADEs) can result in serious outcomes requiring emergency department (ED) visits and hospitalizations. The incidence and severity of ADEs in children with complex chronic conditions (CCCs), who often take multiple medications, is unknown. We sought to describe the characteristics of ADE-related ED visits, including association with CCC st...
