Body weight influences musculoskeletal adaptation to long-term voluntary wheel running during aging in female mice.

Frailty is the hallmark of aging that can be delayed with exercise. The present studies were initiated based on the hypothesis that long-term voluntary wheel running (VWR) in female mice from 12 to 18 or 22 months of age would have beneficial effects on the musculoskeletal system. Mice were separated into high (HBW) and low (LBW) body weight based on final body weights upon termination of experiments.

Dimensions, Function and Applications of the Auricular Muscle in Facial Plastic Surgery.

Purpose: To determine the dimensions and function of the auricular muscle and to consider applications of this muscle in facial plastic surgery.

Methods: Nonpreserved fresh frozen human cadaver dissections from the (HOSPITAL-Blinded) Body Donation program were dissected. The length and width of the superior auricular muscle were measured.

Value of Prophylactic Cervical Thymectomy in Parathyroid Hyperplasia.

Background: In parathyroid hyperplasia (HPT), parathyroid glands within the cervical thymus are a cause for recurrence. As a result of differences in pathophysiology, variable practice patterns exist regarding performing bilateral cervical thymectomy (BCT) in primary hyperplasia versus hyperplasia from renal failure or familial disease. The objective of this study was to capture patients where thymic tissue was found with subtotal parathyroidectomy (PTX) and intended BCT, identify number of thymic supernumerary glands (SNGs), and determine overall cure rate.

Asymmetric bisboranes as bidentate catalysts for carbonyl substrates.

A new class of C(2) symmetric bisoxazaborolidinone compounds is described which exhibits bidentate binding to carbonyl substrates. Using the Diels-Alder reaction as a model system, the catalytic activity of these bis-Lewis acids is probed. Reaction rates and selectivities are observed that are higher than the corresponding mono-Lewis acids.
