Thromboprophylaxis adherence to the ninth edition of American college of chest physicians antithrombotic guidelines in a tertiary care centre: a cross-sectional study.

Rationale: Venous thromboembolic disease is a source of significant morbidity in hospitalized patients. The American College of Chest Physicians published the ninth edition of antithrombotic therapy and prevention guidelines (AT9) in 2012, addressing thromboprophylaxis in hospitalized patients. A notable difference from previous guidelines was utilization of risk assessment models for thrombosis and bleeding to classify patients into risk categories.

Microarrays: biotechnology's discovery platform for functional genomics.

Advances in microarray technology enable massive parallel mining of biological data, with biological chips providing hybridization-based expression monitoring, polymorphism detection and genotyping on a genomic scale. Microarrays containing sequences representative of all human genes may soon permit the expression analysis of the entire human genome in a single reaction. These 'genome chips' will provide unprecedented access to key areas of human health, including disease prognosis and diagnosis, drug discovery, toxicology, aging, and mental illness.

Real-time detection of DNA hybridization and melting on oligonucleotide arrays by using optical wave guides.

The challenge of the Human Genome Project is to increase the rate of DNA sequence acquisition by two orders of magnitude to complete sequencing of the human genome by the year 2000. The present work describes a rapid detection method using a two-dimensional optical wave guide that allows measurement of real-time binding or melting of a light-scattering label on a DNA array. A particulate label on the target DNA acts as a light-scattering source when illuminated by the evanescent wave of the wave guide and only the label bound to the surface generates a signal.

Structural and kinetic studies of the Fab fragment of a monoclonal anti-spin label antibody by nuclear magnetic resonance.

Nuclear magnetic resonance has been used to study the structure of the anti-spin label antibody AN02 combining site and kinetic rates for the hapten-antibody reaction. The association reaction for the hapten dinitrophenyl-diglycine (DNP-diGly) is diffusion-limited. The activation enthalpy for association, 5.
