Radio-Pharmaceuticals

Radiotracers are chemical compounds that are used to diagnose or deliver therapy to specific organs and tissues. The radiotracer consists of a linking molecule, a binding molecule and a radioactive compound. Radiotracer is injected into the body and it binds to specific target cells in the body. The linking molecule binds the radioactive compound to the binding molecule, which then binds to specific cells in body.

The radiotracer decays by emitting ionizing radiation that damages nuclear DNA, thereby stopping division of cells (cancer as well as normal cells). Radiotracers are not something new. In fact, they have been around for 100 years !!

Introduction to Proton Therapy

What is Proton therapy and why should you care?

Conventional Radiation therapy techniques use X-rays (‘photons’) to treat cancer by focussing X-rays on cancer regions. Proton therapy is a technique to treat cancer by the use of ‘protons’. The usage of protons to treat cancer may be advantages in various ways.

Radiation therapy for cancer treatment causes unnecessary exposure to healthy cells also, posing health risks on the patient. We can use Proton therapy for the following reasons.

  • We may want to expose children and pregnant women to lower amount of radiation.

Applications of 3-D printing in orthopedics…

3-D printing in orthopedics is gaining momentum in the production of customized implants, medical devices, and orthotics from diverse materials. 3-D printing technology reduces surgery times, saves money, leads to better stability of the implant in the long run, and improves the clinical outcomes of surgical procedures. 3-D printing applications in orthopedics include:

Introduction to Theranostics

Introduction to Theranostics

Theranostics is a field of medicine that refers to a combination of diagnostic imaging and therapy to treat various types of cancers. Theranostics = Therapy + Diagnostics. Patients are imaged and depending on the tumour size and spread, are identified for therapy. The therapy is given by localized radiation delivered only to the diseased region, reducing the impact on surrounding healthy cells.

Principle of Theranostics

How does it work?

  • Radioactive compound is attached to a linking molecule that is bound to the binding molecule, which attaches to the cancer cell.

Neural Implant Enables Patients: Biomedical innovation

A paralyzed ALS patient uses a brain implant to steer a computer cursor to various targets.

Typing six words per minute may not sound very impressive. But for paralyzed people typing via a brain-computer interface (BCI), it’s a new world record.

To pull off this feat, two paralyzed people used prosthetics implanted in their brains to control computer cursors with unprecedented accuracy and speed. The experiment, reported today in Nature Medicine, was the latest from a team testing a neural system called BrainGate2. While this implant is only approved for experiments right now, researchers say this demonstration proves that such technology can be truly useful to quadriplegics, and points the way toward regular at-home use.

Top 7 Innovations in Healthcare 2014

This year we’ve witnessed amazing innovations in technology with everything from wearable tech like Google Glass or Nike+ to the recent introduction of Coin, one card that stores all your credit cards, debit cards, personal accounts, business accounts and other cards typically filling your wallet. The healthcare industry was no exception to the rise in disruptive technology changing the way people are impacted. What are some of the most influential healthcare technologies you’ve seen appear this year?

Without a doubt the pace at which new technology is impacting our everyday lives is increasing at lightning speeds. As of today, 29% of Americans say their phone is the first thing and last thing they look at everyday which is a telling sign of how connected we are becoming to technology.
