Upper Extremity Deep Vein Thromboses: The Bowler and the Barista.

Effort thrombosis of the upper extremity refers to a deep venous thrombosis of the upper extremity resulting from repetitive activity of the upper limb. Most cases of effort thrombosis occur in young elite athletes with strenuous upper extremity activity. This article reports two cases who both developed upper extremity deep vein thromboses, the first being a 67-year-old bowler and the second a 25-year-old barista, and illustrates that effort thrombosis should be included in the differential diagnosis in any patient with symptoms concerning DVT associated with repetitive activity.

Characterization of a Pterostilbene Dehydrodimer Produced by Laccase of Botrytis cinerea.

ABSTRACT In the interaction between grapevines and Botrytis cinerea, one of the main aspects of pathogenicity is fungal ability to degrade phytoalexins synthesized by the plant in response to infection. Laccase-like stilbene oxidase activity in liquid cultures of B. cinerea has been shown to be related to the decrease of phytoalexin concentrations.

Outpatient management of anticoagulation therapy.

The Seventh American College of Chest Physicians (ACCP) Conference on Antithrombotic and Thrombolytic Therapy provides guidelines for outpatient management of anticoagulation therapy. The ACCP guidelines recommend short-term warfarin therapy, with the goal of maintaining an International Normalized Ratio (INR) of 2.5 +/- 0.

Thyroxine: studies concerning its intrinsic physiological activity.

The importance of the monodeiodination of T4 to T3 in the physiological action of T4 was explored by assessing the role of T4 in maintaining prophylthiouracil (PTU)-treated rats during exposure to 4 degrees C. (PTU inhibits both thyroid hormone biosynthesis and T4 to T3 conversion in peripheral tissues.) Firstly, the effects of cold exposure on the metabolism of T4 in control and PTU-treated rats equilibrated with [125I]T4 (2 microgram/100 g b.
