Echocardiographic Assessment of Cardiovascular Function

Echocardiography was performed as recommended by the American Society of Echocardiography convention and using a Sonosite M-Turbo ultrasound (SonoSite® Inc., Bothell, WA, USA).21 (link) We assessed stroke volume, cardiac output and left ventricular mass index. Further details are given in the online Supplementary Material. Systemic vascular resistance was calculated from mean arterial pressure and cardiac output according to the equation mean arterial pressure=systemic vascular resistance x cardiac output assuming that right atrial pressure=0 mmHg. Stroke work was calculated as stroke volume x systolic blood pressure x 0.0144, and expressed in gram-meters/beat.

Murine Tumor Monitoring and Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
All experiments involving mice were performed in accordance with relevant institutional and national guidelines and were approved by the institutional animal care and use committees at the University of Pennsylvania, Columbia University and University of Michigan prior to experimentation. Starting at two months of age, mice were palpated twice weekly for evidence of tumor. If a potential mass was appreciated, transabdominal ultrasound was performed using a SonoSite M-Turbo ultrasound. If the presence of a tumor was confirmed, mice were examined weekly using ultrasound and general physical exam. If the mouse appeared moribund (decreased spontaneous physical activity, decreased toe pinch reflex, tachycardia, tachypnea, failure to groom, and ruffled coat) indicating low probability of surviving for greater than 24 hours, it was sacrificed for analysis. Tumors were immediately removed, weighed, and dimensions measured and animals were analyzed for evidence of macrometastatic disease.

Cerebrovascular Hemodynamics Measurement by Duplex Ultrasonography

Check if the same lab product or an alternative is used in the 5 most similar protocols
Parameters of cerebrovascular hemodynamics were measured by means of transcranial color duplex ultrasonography. Measurements were recorded using a SonoSite M-Turbo ultrasound machine (FUJIFILM SonoSite, Inc., Bothell, WA, USA) for both extracranial and transcranial recordings. We used a L38x 10–5 MHz transducer probe to determine blood vessel diameters and blood velocities of the internal carotid arteries and vertebral arteries and P21x 5–1 MHz transducer probe on the transtemporal window to determine blood velocities of the middle cerebral arteries in M1 segment. Fig 1 illustrates approximate locations of recordings and some examples of dependencies between measured features of the right middle cerebral artery. Internal carotid arteries and vertebral arteries were evaluated bilaterally with high-resolution B-mode ultrasonography. Peak systolic (pSV), end-diastolic (eDV), and time-averaged maximum (TAMAX) velocities were measured using extracranial Doppler for internal carotid arteries (ICA) and vertebral arteries (VA), and using transcranial color duplex sonography for middle cerebral arteries (MCA). All velocities were measured in cm/s and all vessel diameters were measured in mm. Measurements were recorded in real-time, no images were collected.

Carotid Intima-Media Thickness Measurement

The mean common cIMT was used as a summary measure of the observed degree of atherosclerosis among HIV-infected participants [18 (link),19 (link)]. The mean cIMT was ascertained at the distal 1 cm of the common carotid arteries on images obtained in B-mode along the lateral, anterior, and posterior longitudinal sections of the common carotid artery bilaterally (right and left common carotid) as per the 2008 American Society of Echocardiography Carotid Intima–Media Thickness Task Force protocol.27 A.
A Sonosite M-turbo© ultrasound machine (FUJIFILM Sonosite Inc., Bothell, WA, USA) connected to an 8–12 MHz linear probe was used to obtain still images at the beginning of the R wave, and Sonocal© (version 5 of 2011) was used to measure cIMT in auto-mode as per the manufacturer’s instructions. Plaque was defined as any focal atherosclerotic lesion >1.5 mm on a still image obtained at the beginning of the R-wave.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
