Could microRNA from saliva be a predictor of concussion symptoms in children?

Posted by Shauna White on Thu, Nov 30, 2017 @ 14:11 PM

The issue of concussions has attracted considerable media coverage in recent years. According to the Centers for Disease Control and Prevention, 153 people in the United States die every day from traumatic brain injuries (TBI) that include concussions. Those who survive can face effects that last a few days, or the rest of their lives. Effects of concussions can include impaired thinking or memory, movement, sensation (e.g., vision or hearing), or emotional functioning (e.g., personality changes, depression). In 2013,[1] about 2.8 million TBI-related emergency department visits, hospitalizations, and deaths occurred in the United States.

Discovering the genetics behind Ebola viral disease resistance

Phase I: DNA sample Collection

The Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans. The average EVD case fatality rate is around 50%, however rates have varied from 25% to 90% in past outbreaks. The 2014–2016 outbreak in West Africa was the largest and most complex Ebola outbreak in history, spanning Guinea, Sierra Leone and Liberia.  The World Health Organization released a situation report in June 2016 that confirmed more than 28, 000 cases had been identified or suspected in these areas resulting in more than 11, 000 deaths.[1]

TISMOO: Ground-breaking science for personalized medicine

Posted by Kerry Chatburn on Fri, Sep 22, 2017 @ 09:09 AM

Personalized medicine, also referred to as genomic medicine or precision medicine, is defined by the National Human Genome Research Institute is an approach to healthcare that emphasizes the role an “individual’s genetic profile has in guiding decisions on prevention, diagnosis, and treatment of disease.”

How to execute large-scale DNA sample collection for genetic research - 10 essential considerations

Posted by Kerry Chatburn on Tue, Aug 08, 2017 @ 10:08 AM

Genetic epidemiology, the study of how genetics contribute to health and disease in families and populations, seeks to derive a statistical analysis of how genetics works in large groups. It therefore requires enough DNA samples from a given population to reduce the effect of outliers and ultimately, determine objective truths.

Losing weight – do your genes play a role?

Posted by Erin Carpenter on Wed, May 24, 2017 @ 10:05 AM

With Summer and the promise of warmer weather around the corner, it’s time to start putting away our winter coats and unpack our summer apparel. If you’re like me, you’re wondering if you still fit into last year’s summer outfits and, even more dreadful, if work is required to shed that unwanted winter weight. On the cusp of a new diet and exercise regime, I started wondering just how big of a role my genes play in weight loss. As it turns out, I’m not alone in this pondering. With the complicated interaction of genes, lifestyle, and environmental factors influencing weight, in addition to an increased microscope on the social and economic factors influencing health and wellness, it is not surprising that the genetics of weight loss is a hot research topic.

The SPARK project – Fueling the fire on autism research

Posted by Kerry Chatburn on Thu, May 04, 2017 @ 10:05 AM

The Centers for Disease Control and Prevention (CDC) estimated in 2012 that 1 in 68 children in the US have autism spectrum disorder (ASD), (1 in 42 boys and 1 in 189 girls) [1]. The prevalence of ASD has increased significantly over the past two decades and, while this may be attributed to better diagnostics and an increased awareness, it means we simply do not know enough about the cause(s) of autism and how to best improve the lives of those people living with this condition. While there are some treatments available, such as behavioral therapy, there are no approved medications to treat the core symptoms of autism.

Does marital disruption accelerate aging? An investigation into salivary telomere length, stress, and aging

Posted by Erin Carpenter on Mon, Mar 06, 2017 @ 11:03 AM

I came across a paper recently that combines two research areas that I find extremely interesting: the use of salivary telomere length (TL) as a biomarker to predict biological age, and the psychological and physiological effects of negative stress on health and longevity. The paper, titled Marital disruption is associated with shorter salivary telomere length in a probability sample of older adults by Mark Whisman et al. (2016), explores the hypothesis that marital disruption accelerates cellular aging as characterized by salivary TL. This exciting paper explores the themes of salivary telomere utility in study design, as well as the long-term consequences of stressful life events.[1]

10 must-ask questions to help personal genomics companies get ahead

Posted by Kerry Chatburn on Tue, Feb 28, 2017 @ 11:02 AM

Personal genomics is a branch of human genomics focused on sequencing and analyzing the unique genome of an individual to help determine optimal healthcare decisions… at least that is where it began.  Today, there are companies adopting personal genomics to provide individuals with information on a range of topics from ancestry, diet, athletic training and even optimized wine selection.
