A novel ultrasonic method for evaluation of blood clotting parameters

ConclusionsOur results showed that during blood clotting, the ultrasound velocity and variations in frequency spectrum should be used simultaneously to determine the beginning and duration of blood clot retraction. Our results also showed that blood clot retraction is controlled by the activity of factor XIII.

The objective of this work was to introduce high-intensity ultrasound (HIU) in different positions within a scraped surface heat exchanger (SSHE) and evaluate the crystallization behavior and physical properties of a low saturated, soybean-based fat. The SSHE in this study was composed of one pump (flow rate of 11 L/h), two crystallization barrels (32 °C, 344 rpm), and one pin worker (208 rpm). HIU was placed before the first crystallization step, or barrel 1 (HIU-0), between the two barrels (HIU-1), between barrels 2 and the pin worker (HIU-2) and after complete crystallization in the SSHE (HIU-3). HIU amplitu...

Authors: Membrey B, Miranda S, Lévesque H, Cailleux N, Benhamou Y, Armengol G Abstract Giant cell arteritis is the most common primary vasculitis of large-vessel occurring in subjects over 50 years of age. Many imaging techniques has been evaluated to improve the diagnosis of giant cell arteritis. Among these imaging techniques, ultrasound has shown good performances to detect inflammatory involvement of the temporal arteries as well as branches of the aorta. Several publications and recent EULAR recommendations have emhasized the place of this tool in the diagnosis of giant cell arteritis. PMID: 31...

Transvaginal ultrasound is standard for the assessment of cervical length and selection of patients who may benefit from pessary treatment. Similar to other treatment modalities, the clinical use and placement of pessaries requires regular training. This training is essential for proper pessary placement in patients in emergency situations to prevent preter...

Disruption to the flexor pulley system of the thumb is an infrequent but devastating injury that can lead to significant compromise in both strength and function. Acute rupture leads to pain, weakness, reduced range of motion (ROM), and potential bowstringing of the flexor tendons. Conservative treatment with a pulley ring should be considered in all patients. However, failure of conservative treatment and bowstringing of the thumb are indications for operative intervention. Reconstruction of the oblique pulley system can be performed either in situ or using a free palmaris longus graft. Care should be taken to identify th...
