Electronic Membrane Keeps Your Heart Beating Forever

“My heart will go on, and on..” I can hear Celine Dion now.  And soon, your heart may be able to go on and on as well, thanks to a revolutionary electronic membrane designed to keep your heart rate beating perfectly.  The membrane is made from a  thin, circuit-lined stretchable material that has been developed at the University of Illinois and Washington University by scientists.  This technology may be available for human hearts in 10 to 15 years.

 

At this point, only rabbits can have a perfectly beating heart.  Scientists custom-made the membrane to exactly fit the shape of a particular rabbit’s heart.  In order to do this, they followed two procedures.  Firstly, they scanned the rabbit’s heart while it was still alive and created a 3D model using computer aided tomography (sectional images through penetrating waves). Secondly, using a 3D printer, they assembled the model which they then used as a mould to design the membrane. Once the membrane was created, they took the heart out of the rabbit, put the membrane on it and kept it beating at its perfect pace.

John Rorgers, materials researcher at the University of Illinois, stated that this technology is just like the natural membrane that is already on the heart, not just a pacemaker.  However, this artificial pericardium is equipped with high quality, man-made technology that can sense and communicate with the heart in ways that are relevant to clinical cardiology.  Igor Efimov, Washington University’s biomedical engineer, says that this is a big advancement.  The circuits are a combination of sensors that continuously track the tissues’ way of behaving and electrodes that exactly control the heart muscles’ movement:

If the heart were to suffer a heart attack, the membrane can apply therapy.  It can apply stimuli that can stop sudden cardiac death. What an amazing feat!!

Indoor pollution

There are two terms signifying the ill health due to indoor air pollution- sick building syndrome(SBS) and building related illness(BRI).

                                    

SBS is the existence of persistent, non-specific symptoms (e.g., eye, nose, and throat irritation; fatigue; headaches) that occur in more than 20-25% of a building's occupants. it dissipates once these inhabitants leave the building. It is usually a diagnosis of exclusion. 


BRI refers to clinically diagnosed disease(s) in building occupants and have defined diagnostic criteria, recognizable causes, and defined treatments. Typically individuals suffering from a BRI require prolonged recovery times after leaving the suspected environment, and successful remediation or mitigation requires elimination of exposure to the causative agents.

android medical app woooooooooooooow

http://medicinenopain.blogspot.com/

 best of the best

1. Medscape


One of the most anticipated apps to hit Android, Health care professionals had been waiting eagerly for this comprehensive medical application. Medscape was just recently released on the Android Market and has already become the number one downloaded medical app for the Android platform.


The amount of free content provided by Medscape is absolutely mind numbing and seems to continuously grow with each update. 7,000+ drug references, 3,500+ disease clinical references, 2,500+ clinical images and procedure videos, robust drug interaction tool checker, CME activities, and more.


Medscape is a great drug reference app — but many don’t realize it’s also a mini-textbook packed with protocols for disease pathologies — great for a quick reference and refreshing you medical knowledge. Its not as detailed as the famous Pocket Medicine Red Book — but it does more than an adequate job of providing clinical pearls from the most common to less common pathologies. On top of this, the application has instructional medical procedure videos and pictures.


2. Epocrates


The free version of Epocrates is considered by many to be an essential drug reference. Useful and easy-to-learn features like the pill identifier, several medical calculators, and drug interaction checker make Epocrates a favorite of clinicians and students alike.


Of note, Epocrates recently announced support for the premium versions of Epocrates on the Android platform.


As with other popular and new Android apps, Epocrates is not available for Android users with older operating systems (version 1.5 or older).


3. Skyscape


This app makes our top ten list for two major reasons: First, until recently Skyscape has been the only high-quality all-in-one type app for Android. Many of the quality android medical apps we have reviewed, such as the Red Book and Netter’s Anatomy have worked within Skyscape’s universal app. Second, it’s available on all Android operating system versions.
