Falsely elevated thyroid hormone levels associated with fibrin interference in patients receiving oral anticoagulant therapy.

Objective: Unique clinical courses were observed in two asymptomatic patients receiving warfarin who referred to our hospital because of suspected central hyperthyroidism. We eventually diagnosed these patients with falsely elevated thyroid hormone levels caused by macroscopically invisible fibrin. Although false results caused by fibrin interference in vitro have been identified in various immunoassays, especially in blood samples from patients receiving anticoagulant therapy, no studies on thyroid function testing have been reported.

Current status and recent changes in blood pressure and dietary salt consumption in Japanese individuals.

: Treatment of hypertension has recently shown remarkable advances. It is quite important to survey the current general status of blood pressure (BP) and recent changes to verify whether people are benefitting from these advances. The present study aimed to investigate the current status of, and recent changes in, BP, the prevalence and treatment rate of hypertension, the achievement rate of target BP, and salt intake in Japanese individuals.

Ubiquitin-Proteasome Dependent Regulation of the GOLDEN2-LIKE 1 Transcription Factor in Response to Plastid Signals.

Arabidopsis (Arabidopsis thaliana) GOLDEN2-LIKE (GLK) transcription factors promote chloroplast biogenesis by regulating the expression of photosynthesis-related genes. Arabidopsis GLK1 is also known to participate in retrograde signaling from chloroplasts to the nucleus. To elucidate the mechanism by which GLK1 is regulated in response to plastid signals, we biochemically characterized Arabidopsis GLK1 protein.
