Technetium uptake predicts remission and relapse in Grave's disease patients on antithyroid drugs for at least 1 year in South Indian subjects.

Context: Most of the information on remission related factors in Grave's disease are derived from Western literature. It is likely that there may be additional prognostic factors and differences in the postdrug treatment course of Grave's disease in India.

Aim: To study factors which predict remission/relapse in Grave's disease patients from South India.

The diagnostic role of 18-fluorodeoxyglucocose-positron emission tomography/computed tomography in occult bacteremia searching underlying primary disease.

18-Fluoro-2-deoxy-D-glucose(FDG) is a structural analog of 2-deoxyglucose and accumulates in malignant tissues but also at sites of infection and inflammation. For this reason, FDG PET or PET/CT has great advantage in understanding of underlying pathology in assessment of FUO (Fever of unknown origin). However, till today, there are limited studies about the role of FDG PET or PET/CT in evaluation of FUO.

Injectable nanomaterials for drug delivery: carriers, targeting moieties, and therapeutics.

Therapeutics such as nucleic acids, proteins/peptides, vaccines, anti-cancer, and other drugs have disadvantages of low bio-availability, rapid clearance, and high toxicity. Thus, there is a significant need for the development of efficient delivery methods and carriers. Injectable nanocarriers have received much attention due to their vast range of structures and ability to contain multiple functional groups, both within the bulk material and on the surface of the particles.

Therapeutic RNA aptamers in clinical trials.

RNA aptamers can fold into complex structures and bind with high affinity and selectivity to various macromolecules, viruses, and cells. They are isolated from a large pool of nucleic acids by a conceptually straightforward iterative selection process called SELEX. Aptamers have enormous potential as therapeutics due to their ability to bind to proteins and specifically inhibit their functions with minimal or no harmful side-effects.

A nanoscale drug delivery carrier using nucleic acid aptamers for extended release of therapeutic.

Unlabelled: We have synthesized, characterized, and optimized a novel nano drug-delivery carrier that utilizes the versatile properties of nucleic acid for programmable and on-demand drug release. The drug-delivery carrier consists of 15 nm gold nanoparticles (AuNPs) functionalized with drug binding DNA aptamers via single-stranded (ss) anchor DNA. The presence of anchor DNA makes the nanocarrier flexible to be reprogrammed with various aptamers.

High-transfer-rate high-capacity holographic disk data-storage system.

We describe the design and implementation of a high-data-rate high-capacity digital holographic storage disk system. Various system design trade-offs that affect density and data-rate performance are described and analyzed. In the demonstration system that we describe, high-density holographic recording is achieved by use of high-resolution short-focal-length optics and correlation shift multiplexing in photopolymer disk media.
