Approach to Different Types of Inferior Vena Cava Leiomyosarcomas: A Vascular Surgeon's Perspective.

Leiomyosarcoma (LMS) is a rare smooth muscle tumor, and only a few cases have been reported with involvement of the inferior vena cava (IVC). Inferior vena cava LMS is more often silent and usually has a poor prognosis as the patients present late. We present this case series to showcase the different approaches to surgical resection, as each tumor had a different location in the IVC.

A Giant Right Atrial Hemangioma- Case Report.

A primary cardiac tumor is sporadic. Most cardiac tumors are benign, with cardiac myxoma being the most common tumor. The incidence of cardiac hemangioma is extremely low.

An electrochemical biosensor for the rapid detection of erythropoietin in blood.

A label free electrochemical detection method for the rapid detection of recombinant human erythropoietin (rhuEPO) has been developed. In this method, we modified the rhuEPO structure for its direct sensing without using a complex signal amplification strategy. The protein was selectively extracted from blood plasma sample using target-specific magnetic beads.

Towards interference free HPLC-SERS for the trace analysis of drug metabolites in biological fluids.

Sofosbuvir metabolite, 2'-deoxy-2'-fluoro-2'-C-methyluridine (PSI-6206) was studied for the first time by surface enhanced Raman spectroscopy (SERS) using the paper-based SERS substrate. The quantification limit of PSI-6206 by SERS was found to be 13ngL (R value=0.959, RSD=5.

Generating monomeric 5-coordinated microperoxidase-11 using carboxylic acid functionalized silver nanoparticles: A surface-enhanced resonance Raman scattering analysis.

Microperoxidase-11 (MP-11), a heme undecapeptide obtained by proteolytic digestion of cytochrome c, resembles peroxidase enzyme when its heme center is 5-coordinated with a vacant sixth coordination site. However, MP-11 always tends to aggregate in both solution and on surface and eventually forms the 6-coordinated heme. Thus, the present study investigates the immobilization strategy of MP-11 on nanoparticle surface in order to generate monomeric 5-coordinated MP-11 and make them as an efficient biocatalyst.
