Brown University Study: Biochip measures glucose in saliva, not blood

Researchers at Brown University have developed technology that can measure glucose in human saliva.

Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances.

Tripping the light fantastic Each plasmonic interferometer – thousands of them per square millimeter – consists of a slit flanked by two grooves etched in a silver metal film. The schematic shows glucose molecules “dancing” on the sensor surface illuminated by light with different colors. Changes in light intensity transmitted through the slit of each plasmonic interferometer yield information about the concentration of glucose molecules in solution.Credit: Domenico Pacifici 

Diabetes Tech News: Medtronic Launches First-Of-Its-Kind mySentry™ Remote Glucose Monitor

Medtronic announces mySentry and I rejoice. Their new innovation does sound familiar...

mySentry Allows Caregivers to See Real-Time Insulin Pump Information and Glucose Trends from Another Room

MINNEAPOLIS – January 4, 2012 – Today, Medtronic, Inc. (NYSE:MDT) announced U.S. Food and Drug Administration (FDA) approval and U.S. market launch of the first-of-its-kind mySentry™ Remote Glucose Monitor, which allows a parent or caregiver to monitor from another room a patient’s MiniMed Paradigm® REAL-Time Revel™ System. The remote glucose monitor also marks the launch of a new category of Connected Care solutions that will provide people with diabetes and their caregivers convenient options to access their diabetes management information.

Perhaps more then any other chronic dieses, management of day-to-day diabetes lends itself to cutting edge technology. While I'm always grateful for the advancements that have already been made, I'd like to see more and see it faster. 

Even if you don't use a Medtronic device (Arden uses a DexCom CGM) this news is fantastic. Wireless technology like this is sorely needed and Medtronic's announcement will serve us all well, spurning other manufacturers to move forward as quickly as possible so not to be left behind. It is also a signal to other companies that the FDA is allowing clearance for technology such as this. That knowledge will make it easier for smaller companies to get into the game. Many device manufacturers are smaller and less profitable then you may imagine and they can't afford to get trapped into a protracted submission process with the government.

I love the FDA saying yes, I love Medtronic trying and I look forward to finding out what is next - please just don't price us all out of when your products come to market.

Medtronic's complete press release is at this link.

ps. It's time to let Insulet give us their smaller pods FDA - I mean really... which ever device lobbyist has you holding this up (my supposition)... they've gotten their monies worth, time to think about the people again.

iPhone 4 Initial thoughts

My phone arrived this morning (via FedEx) while I was in the shower, I say that to remind you all to presign and leave the form on your front door so you won’t miss your phone’s arrival.

Activation

I backed up my 3G phone and then began the activation process which took just a few (less then 5) minutes and was flawless.  I did a restore from that backup and was up and running in about 15 minutes. Everything was smooth.

First impression

I’m so impressed that Apple has redesigned the iPhone so much over the past few years yet it’s very reminiscent of the original... but at the same time, it’s completely different and improved.  It feels great in my hand and looks like a million bucks.

Display

As advertised the display is amazing, crisp and vibrant in a way that I hadn’t anticipated.  

Camera

The camera is a major upgrade, the HD video is impressive and the stills are superb.  I’m not a super technophile about these things so take my thoughts based on that.  My impression is that you’ll be very happy with the camera. Here are my samples.

It’s faster

Apps respond faster then on my 3GS even on the apps that I’d experienced lag with in the past. Navigating the UI is quick.

Battery

The phone arrived charged and after 9 hours of use the battery reads 80%.  I took pictures, video, uploaded things to MobileMe, talked on the phone and used a lot of continuous iPod play.

Other Stuff

I’ve already uploaded a number of things to my MobileMe gallery and the integration is seamless. 

iBooks is more responsive on the iPhone4 then on 3GS

I’m going to go play with my new iPhone some more... back later...

FaceTime - I don’t have anyone to FT with yet but I can tell you this much... I’m way more aware of my double chin today then I was yesterday.

iPhone4

Today we aren’t going to talk about diabetes, at least not directly.  Today we talk about my new iPhone4 which I was lucky enough to receive a day early (thanks Apple!).  

I’ll be posting pictures and video from my new iPhone as well as my thoughts and reactions to the phone.  What do I want in return, nothing.  However, if you find yourself really enjoying my posts and want to say thank you, I can’t think of a better way then by making a tax deductible donation to my daughter Arden’s 2010 JDRF Walk to find a cure for her type I diabetes at this link - Arden walks for @JDRFEasternPA

I’ll be updating here, on Twitter with my Arden’s Day account @ArdensDay and on the MacRumors forum

To make this experiment a total Apple experience I’ll be hosting all of the pictures and videos on my MobileMe Gallery - http://gallery.me.com/skca/100928

Please use the “Email Me” button below to be added to Arden’s email list. Special thanks to Arden’s brother Cole for helping with the motion videos.

UPDATE: My initial thoughts on the phone are here

I wish I may... have Mac compatible software

Hello Makers of various insulin pumps, CGMs, and meters.  How are you?  I wanted to drop you a note and say that we really appreciate all that you do!  Your inventions are quite literally saving us (well those of us with good insurance) so I feel just a little weird complaining but nevertheless here I go.  

Not one of us wants to keep logs by hand but some of us have to because.  we have Apple computers and your software only runs on a Windows machine.  I know that Apple only holds about a 13% market share in home computing but please keep these things in mind: 13% is second only to Windows, that number is growing steadily, Apple computers are (generally) owned by the more tech savvy section of society and your devices are geared toward those people.  Lastly, it really wouldn’t take that much effort to port your software over to the Mac OS.

Anyway, give that some consideration please and let me know what you decide.

Signed,

Patiently Waiting

I Emailed Abbott today about this very thing.  I am considering purchasing a no frills laptop just for this purpose but I really can't afford to do that.  Excel is still my friend for now.

Sophia's Mom,

Like a net book maybe... That's a very good idea! Though I would so dislike using Windows again... :)
