Walmer, R. W., Ritter, V. S., Sridharan, A., Kasoji, S. K., Altun, E., Lee, E., … Chang, E. H. (2023, October 12). Journal of Clinical Medicine.

By: R. Walmer n, V. Ritter *, A. Sridharan  n, S. Kasoji n, E. Altun *, E. Lee *, K. Olinger *, S. Wagner* ...

author keywords: chronic kidney disease; contrast-enhanced ultrasound; kidney lesions; performance metrics; screening tool
topics (OpenAlex): Renal cell carcinoma treatment; MRI in cancer diagnosis; Renal and related cancers
TL;DR: In CKD patients, CEUS is a potential low-risk option for screening kidney lesions, and may be particularly beneficial for CKD IV/V patients, where kidney preservation techniques are highly relevant. (via Semantic Scholar)

Classifying Kidney Disease in a Vervet Model Using Spatially Encoded Contrast-Enhanced Ultrasound Perfusion Parameters

AlHmoud, I. W., Walmer, R. W., Kavanagh, K., Chang, E. H., Johnson, K. A., & Bikdash, M. (2022, November 30). Ultrasound in Medicine & Biology.

By: I. AlHmoud *, R. Walmer n, K. Kavanagh *, E. Chang*, K. Johnson n & M. Bikdash *

author keywords: Contrast ultrasound; Perfusion imaging; Diabetic kidney disease; Segmentation; Model parameters; Regression analysis
MeSH headings : Animals; Chlorocebus aethiops; Contrast Media; Diabetes Mellitus, Type 2; Microcirculation; Kidney / blood supply; Ultrasonography / methods; Diabetic Nephropathies / diagnostic imaging; Perfusion; Insulins
topics (OpenAlex): Ultrasound and Hyperthermia Applications; MRI in cancer diagnosis; Ultrasound Imaging and Elastography
TL;DR: Perfusion index features, with blood pressure, were the best classifiers between cohorts, suggesting CEUS has the potential to detect early microvascular changes, providing insight into disease-related structural changes in the kidney. (via Semantic Scholar)

By: C. Marvin *, S. Ding *, R. White n, N. Orlova *, Q. Wang*, E. Zywot *, B. Vickerman *, L. Harr* ...

author keywords: drug delivery; photolysis; prodrugs; red blood cells; vitamin B12
MeSH headings : Animals; Bridged-Ring Compounds / chemistry; Drug Carriers / chemistry; Drug Delivery Systems / methods; Erythrocytes / cytology; Female; Flow Cytometry; Humans; Mice; Photolysis; Prodrugs / chemistry; Taxoids / chemistry; Vitamin B 12 / chemistry
topics (OpenAlex): Erythrocyte Function and Pathophysiology; Neonatal Health and Biochemistry; Microfluidic and Bio-sensing Technologies
TL;DR: Herein, the use of red blood cells (RBCs) as carriers of cytoplasmically interned phototherapeutic agents is described, and photolysis promotes drug release from the RBC carrier thereby providing the means to target specific diseased sites. (via Semantic Scholar)
