A New Era in Federal Quarantine and State Certification Diagnostics at Clean Plant Centers in the USA.

Quarantine and certification programs exist to prevent the entry or spread of harmful pests and pathogens into agricultural systems.

Management of Atopic Hand Dermatitis.

Atopic hand dermatitis (AHD), a manifestation of atopic dermatitis, can have a profound negative effect on a patient's disease-related quality of life due to its visibility, chronic nature, and overall discomfort that it causes.
