Geometrical confinement of gadolinium-based contrast agents in nanoporous particles enhances T1 contrast.
Jeyarama S. Ananta,Biana Godin,Biana Godin,Richa Sethi,Loïck Moriggi,Xuewu Liu,Xuewu Liu,Rita E. Serda,Rita E. Serda,Ramkumar Krishnamurthy,Raja Muthupillai,Robert D. Bolskar,Lothar Helm,Mauro Ferrari,Lon J. Wilson,Paolo Decuzzi,Paolo Decuzzi +16 more
TL;DR: Nanoscale confinement offers a new and general strategy for enhancing the contrast of gadolinium-based contrast agents by confining contrast agents inside the nanoporous structure of silicon particles.
Effects of Combined Exenatide and Pioglitazone Therapy on Hepatic Fat Content in Type 2 Diabetes
Padma Sathyanarayana,Medhavi Jogi,Raja Muthupillai,Ramkumar Krishnamurthy,Susan L. Samson,Mandeep Bajaj +5 more
TL;DR: It is concluded that combined in patients with T2DM, pioglitazone and exenatide therapy is associated with a greater reduction in hepatic fat content as compared to the addition of piog litazone therapy.

Clinical validation of free breathing respiratory triggered retrospectively cardiac gated cine balanced steady-state free precession cardiovascular magnetic resonance in sedated children
Rajesh Krishnamurthy,Amol Pednekar,Lamya A Atweh,Esben Vogelius,Zili David Chu,Wei Zhang,Shiraz A. Maskatia,Prakash Masand,Shaine A. Morris,Ramkumar Krishnamurthy,Raja Muthupillai +10 more
TL;DR: The free breathing RT- SSFP sequence allows diagnostic images in sedated children with significantly better edge definition when compared to MN-SSFP, without any penalty for total scan time.
Gadonanotubes as magnetic nanolabels for stem cell detection.
Lesa A. Tran,Ramkumar Krishnamurthy,Raja Muthupillai,Maria da Graça Cabreira-Hansen,James T. Willerson,Emerson C. Perin,Lon J. Wilson +6 more
TL;DR: The performance of gadolinium-containing carbon nanocapsules, or gadonanotubes, as a new T₁-weighted magnetic resonance imaging (MRI) intracellular labeling agent for pig bone marrow-derived mesenchymal stem cells (MSCs) is reported.
