Application of high-resolution ultrasonic spectroscopy for detection of the plasmin activity toward β-casein.

High-resolution ultrasonic spectroscopy (HR-US) was applied for precise detection of plasmin activity towards β-casein in buffer at pH 7.8 and 37 °C. The evolution of ultrasonic velocity and ultrasonic attenuation measured at 15.

Advances in Analysis of Milk Proteases Activity at Surfaces and in a Volume by Acoustic Methods.

This review is focused on the application of surface and volume-sensitive acoustic methods for the detection of milk proteases such as trypsin and plasmin. While trypsin is an important protein of human milk, plasmin is a protease that plays an important role in the quality of bovine, sheep and goat milks. The increased activity of plasmin can cause an extensive cleavage of β-casein and, thus, affect the milk gelation and taste.

Application of high-resolution ultrasonic spectroscopy for real-time monitoring of trypsin activity in β-casein solution.

High-resolution ultrasonic spectroscopy (HR-US) was applied for real-time monitoring of β-casein hydrolysis by trypsin at various conditions for the first time. The technique is based on the precision measurement of hydration changes proportional to the number of peptide bond hydrolyzed. As HR-US exhibits ultrasonic transparency for most solution, the analysis did not require optical transparency like for 2,4,6-trinitrobenzenesulfonic acid (TNBS) assay.

Effectiveness of Initiating Deep Vein Thrombosis Prophylaxis in Patients With Stroke: An Integrative Review.

Venous thromboembolism (VTE) is a frequent and potentially fatal complication of immobility caused by cerebrovascular disease. This review examines the efficiency of deep vein thrombosis (DVT) prophylaxis methods. Patients with stroke initiated on DVT prophylaxis were compared with those who did not have any prophylaxis.
