BACKGROUND AND OBJECTIVES: Delivery of inadvertent high tidal volume (VT) during positive pressure ventilation (PPV) in the delivery room is common. High VT delivery during PPV has been associated with haemodynamic brain injury in animal models. We examined if VT delivery during PPV at birth is associated with brain injury in preterm infants <29 weeks' gestation. METHODS: A flow-sensor was placed between the mask and the ventilation device. VT values were compared with recently described reference ranges for VT in spontaneously breathing preterm infants at birth...

The favorable etching time of alpha tracks registered in CN-85 solid-state nuclear track detector was explored by chemical etching heated by three different techniques: the classical water bath, unconventional microwave, and ultrasound techniques. The parameters that affect the etching of the tracks, namely the rate of bulk etching (VB), the rate of track etching (VT), the ratio of track etching (V), the critical angle (θc), and the registration efficiency (η), were determined. The favorable etching times to develop the highest number of registered tracks in CN-85 irradiated with alpha particles emanated from a 241Am source was found to be 30, 10, and 20min for water bath, microwave, and ultrasound heating techniques, respectively...

Liver is the heaviest internal organ of the human body and performs many vital functions. Prolonged cirrhosis and fatty liver disease may lead to the formation of benign or malignant lesions in this organ, and an early and reliable evaluation of these conditions can improve treatment outcomes. Ultrasound imaging is a safe, non-invasive, and cost-effective way of diagnosing liver lesions. However, this technique has limited performance in determining the nature of the lesions. This study initiates a computer-aided diagnosis (CAD) system to aid radiologists in an objective and more reliable interpretation of ultrasound images of liver lesions...

Melanoma is an incurable disease for which alternative treatments to chemotherapy alone are sought. Here, using a melanoma model, we investigated the antitumor potential of combining ultrasound (US) with poly(lactic-co-glycolic acid) (PLGA) microspheres loaded with doxorubicin (DOX). The aim was to achieve synergistic tumoricidal activity through direct and indirect US-mediated damage of tumor cells combined with sustained and potentially controllable release (when combined with US) of DOX from microspheres...

The rate at which lethal intracellular ice forms during sperm cryopreservation is highly dependent on the cooling protocol. The present work compares two cooling protocols for use with Iberian ibex (Capra pyrenaica) sperm by assessing the effects on the motility, viability, and size of frozen-thawed sperm cells. Ejaculates, obtained from six adult ibex males via transrectal, ultrasound-guided massage of the accessory sex glands plus electroejaculation if necessary, were cooled via either 1) Protocol 1 (decelerating cooling), involving cooling in liquid nitrogen vapor from 5 °C to -35 °C (40 °C/min), from -35 °C to -65 °C (17 °C/min), and then from -65 °C to -85 °C (3 °C/min); or 2) Protocol 2 (accelerating cooling) involving cooling in a biological freezer from 5 °C to -5 °C (4 °C/min), from -5 °C to -110 °C (25 °C/min), and then from -110 °C to -140 °C (35 °C/min)...

Enzyme-induced articular cartilage degeneration resembling osteoarthritis was evaluated using a newly defined acoustic parameter, the "averaged magnitude ratio" (AMR), which has been suggested as an indicator of articular cartilage degeneration. In vitro experiments were conducted on porcine cartilage samples digested with trypsin for 2 h (n = 10) and 4 h (n = 13) and healthy control samples (n = 13). AMR was determined with 15- and 25-MHz ultrasound, and the integrated reflection coefficient (IRC) and apparent integrated backscattering coefficient (AIB) were also calculated for comparison...

Effective postoperative analgesia after emergency caesarean section is important because it provides early recovery, ambulation and breast-feeding. The ultrasound-guided erector spinae plane block has been orginally described for providing thoracic analgesia at the T5 transverse process by Forero et al. We performed post-operative bilateral erector spinae plane blocks with 20ml bupivacaine 0.25% at the level of the T9 transverse process in a pregnant woman after caesarean section. In this report, we described that bilateral erector spinae plane block at T9 level provides effective and long-lasting postoperative analgesia for lower abdominal surgery...
