Nerd Alert: The Future of Early Cancer Detection

cancer 1By now you all have probably figured out that I’m a bit of a nerd; although, sildenafil ampoule a cool nerd ;) .  I love having the chance to learn and experience something new, ampoule especially when science and technology are involved.  Last night I did learn something new and it got my nerdy antennas buzzing: the possibility of early cancer detection.

Cancer is a silent killer.  The cells in our body mutate and multiply at an unhealthy rate, and then BAM-BAM, we experience the symptoms.  Sometimes, unfortunately, the symptoms come when it’s too late.  What would our world be like without cancer?  How can technology help to solve this problem?  Biomedical technology is continually participating in cutting edge research for drugs and procedures to eradicate cancer, but that’s only half the issue, what about early detection?  If we could detect cancer in it’s early stages, then theoretically, more people will be saved, right?

Well, Jorge Soto and his team are on that task!  They’ve developed a prototype that allows early cancer detection by using microRNAs.  MicroRNAs are the intermediate proteins in the conversion of DNA to RNA.  They contain much smaller and similar sequences than DNA, so it’s been difficult in the past to categorize them.
cancer 3Jorge Soto’s theory is that cancer cells use specific microRNA patterns to multiply; therefore, if we discover the specific patterns for certain cancer types then we can detect them earlier!  Even more amazing is the prototype he’s using to scan the microRNA proteins.  His team constructed a cylindrical device that holds the plastic wells containing the microRNAs and uses an iPod as a scanner to detect the proteins.  The device is cost-effective and so far quite reliable.  They’re been able to accurately sequence microRNA protein patterns for pancreatic, lung, breast, and hepatic cancer!  Wow – great minds, ingenuity, and technology at its finest! :)

This technology is still in infancy, but it’s on the right path.  The future is endless for Jorge Soto and his team – they’re on the path of discovering something so great and beneficial for medical science and countless lives.  I look forward to seeing what else they develop.

I would love to hear your thoughts. Happy reading :)

Nerd Alert: Measuring Brainwaves Could Lead To An Objective Autism Diagnosis

Learning about autism has always been a passion of mine.  There’s been immense debate on its origins and reseachers have found that it’s multifactorial.  For those who do not know what autism is, sildenafil case  I shall describe it briefly: Autism is a neural developmental disorder characterized by repetitive movements (i.e. hand flapping) and impaired social interaction and communication.  The mechanism is still not completely understood but researchers have learned that the neural synapses in the brain fail to connect and organize, which results in regressed development around the age of 2.

Today I read an article in Popular Science about a study that used EEG wave patterns to possibly diagnose autism.  Electroencephalogram recordings (EEGs) measure wave patterns in the brain.  It’s a non-invasive method where a patient wears a skull cap that contains multiple electrodes and wires to measure brain activity.

Since autism is associated with faulty brain connectivity, this study makes complete sense to use in diagnosing! :) In fact, the researchers of this study found an inverse correlation between electrical brain activity and autism severity – meaning, the more severe the autism symptoms, the patient demonstrates weaker brain activity and slower incoming processing time.  This study is quite important for autism research.  It may not establish it’s origin, but it’ll allow for a more objective, faster diagnosis and the ability to categorize individuals along the autism spectrum.  Isn’t that exciting?! I think so! :)
