Surface albedo measurements and surface type classification from helicopter-based observations during MOSAiC.

Global climate change poses significant societal and political challenges. The rapid increase in the near-surface air temperatures and the drastic retreat of the Arctic sea ice during summer are not well represented by climate models. The data sets introduced here intend to help improving the current understanding of the ongoing Arctic climate changes.

Reference Values and Release Kinetics of B-Type Natriuretic Peptide Signal Peptide in Patients with Acute Myocardial Infarction.

Background: The signal peptide for human B-type natriuretic peptide preprohormone (BNPsp), which is released from cardiomyocytes, is increased in plasma of patients with acute myocardial infarction (AMI); however, its exact release kinetics have not been defined.

Methods: We measured BNPsp and high-sensitivity cardiac troponin T (hs-cTnT) in a reference group of individuals without structural heart disease (n = 285) and determined the release kinetics of these biomarkers in patients (n = 29) with hypertrophic obstructive cardiomyopathy undergoing transcoronary ablation of septal hypertrophy (TASH), a procedure allowing exact timing of onset of iatrogenic AMI. Blood samples were collected before TASH and at numerous preselected time points after TASH.

Mural folliculitis and alopecia caused by infection with goat-associated malignant catarrhal fever virus in two sika deer.

Two sika deer from a zoo in Florida were examined because of chronic hair loss and skin lesions. No common causes of alopecia were identified in either deer. One deer was treated with prednisone, but the condition worsened when the dosage was decreased.

Bupivacaine with and without epinephrine for intercostal nerve block.

In a double-blinded study, 15 American Society of Anesthesiologists class I or II patients, following lateral thoracotomy with general anesthesia, were randomized into two groups for intercostal nerve block with either bupivacaine, 0.5%, and epinephrine, 1:200,000, or plain bupivacaine, 0.5%.

Receptor characteristics of the rat mammary carcinoma cell line 64-24.

Saturable binding of androgens, glucocorticoids, and triiodothyronine was found in the 64-24 hormone-responsive rat mammary carcinoma cell line. Androgen receptors had a dissociation content (Kd) for methyltrienolone of 3.4 X 10(-10) M and a binding capacity of approximately 10,000 sites/cell in whole cells.
