High PRF ultrafast sliding compound doppler imaging: fully qualitative and quantitative analysis of blood flow. Phys Med Biol. 2018 Jan 15;: Authors: Kang J, Jang WS, Yoo Y Abstract Ultrafast compound Doppler imaging based on plane-wave excitation (UCDI) can be used to evaluate cardiovascular diseases using high frame rates. In particular, it provides a fully quantifiable flow analysis over a large region of interest with high spatio-temporal resolution. However, the pulse-repetition frequency (PRF) in the UCDI method is limited for high-velocity flow imaging since it leverages between the number of plane-wave angles (<i>N</i>) and acquisition time. In this paper, we present high PRF ultrafast sliding compound Doppler imaging method (HUSDI) to improve quantitative flow analysis. With the HUSDI method, full scanline images (i.e., each tilted plane wave data) in a Doppler frame buffer are consecutively summed using a sliding window to create high-quality ensemble data so that there is no reduction in frame rate and flow sensitivity. In addition, by updating a new compounding set with a certain time difference (i.e., sliding window step size or <i>L</i>), the HUSDI method allows various Doppler PRFs with the same acquisition data to enable a fully qualitative, retrospective flow assessment. To evaluate the performance of the proposed HUSDI method, simulation, <i>in vitro</i> and <i>in vivo</i> studies were con...

Publication date: Available online 11 November 2019Source: MethodsAuthor(s): Jennifer I. Brown, Brent D.G. Page, Adam FrankelAbstractProtein arginine N-methyltransferases (PRMTs) are a family of 9 enzymes that catalyze mono- or di-methylation of arginine residues using S-adenosyl-L-methionine (SAM). Arginine methylation is an important post-translational modification that can regulate the activity and structure of target proteins. Altered PRMT activity can lead to a variety of health issues including neurodevelopmental disease, autoimmune disorders, cancer, and cardiovascular disease. Thus, developing a robust mechanistic ...

Modifying crystallization of PLLA has been found to be an efficient way to improve its mechanical and heat resistance properties. In this wok, 4, 4′-diphenylmethane diisocyanate (M) and benzohydrazine (P) were employed into PLLA melt to in-situ form nucleating agents. The in-situ melting reaction was confirmed by a nu...

The dependence of the peak on v can be attributed conventionally to sluggish charge transfer rates and the solution resistance. This redox species has been proved to exhibit extremely fa...

Authors: Baqir H, Nayani K, Mian A, Mian AI Abstract Writing has always been a part of medicine, but it was largely used as a means to disseminate objective data. With changing times, qualitative writing in the form of narrative medicine (NM) is fast coming to the forefront. Data in the field from high-income countries have shown an enhancement in empathy and professionalism alike, for both patients and health care practitioners. Studies also elucidate the benefits of incorporating NM into medical curricula. However, there is scant literature from low-income to middle-income countries concerning NM. In this brief r...
