Introduction: To examine the relationship between elevated basal serum tryptase levels (BST), a marker of total mast cell mass, and bone mineral density (BMD) in patients with anaphylactic reactions and signs of mastocytosis. Methods: Retrospective evaluation of patient charts at an allergy unit. Patients with BST levels above 20 ng/ml were eligible if clinical and follow-up data and results of...

OBJECTIVE To determine whether the use of additional preoperative imaging was cost-effective compared with bilateral neck exploration (BNE) for the treatment of primary hyperparathyroidism in patients with negative findings on scans with technetium Tc 99m sestamibi. DESIGN We performed a cost-effectiveness analysis. The decision whether to proceed to BNE or obtain additional preoperative imag...

Ambulatory blood pressure (BP) monitoring has become useful in the diagnosis and management of hypertensive individuals. In addition to 24-hour values, the circadian variation of BP adds prognostic significance in predicting cardiovascular outcome. However, the magnitude of circadian BP patterns in large studies has hardly been noticed. Our aims were to determine the prevalence of circadian BP ...

The proteins that bind to rat liver 5.8 S ribosomal ribonucleic acid were identified by affinity chromatography. The nucleic acid was oxidized with periodate and coupled by its 3'-terminus to Sepharose 4B through and adipic acid dihydrazide spacer. The ribosomal proteins that associate with the immobilized 5.8 S rRNA were identified by polyacrylamide gel electrophoresiss: they were L19, L8, and...
