Obesity, Hypertension and Cardiovascular Risk in Italian Youth

Posted by Erin Carpenter on Thu, May 24, 2018 @ 09:05 AM

Cardiovascular disease (CVD) is a very serious and life-threatening condition. Hypertension (HT) is a significant risk factor contributing to CVD, and also one that may be detected early and controlled; thus, reducing CVD-mediated mortality and morbidity. Recently, the growing trend of adolescent obesity has predisposed youth to both HT and CVD, and has become a serious health concern within the population. Obesity appears to have both genetic and environmental/nutritional factors, and given the risk to health, merits dedicated research to understand and, hopefully, combat it.

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.

8 facts most people don’t know about DNA from saliva

Posted by Scott Rabuka on Wed, Jan 18, 2017 @ 10:01 AM

Since the launch of this blog, The Genetic Link, in 2009, we have published numerous articles, interviews, technical information and infographics to share what we know about DNA from saliva. Saliva is the human body’s most accessible bio-fluid but, after 7 years, we continue to be surprised at how often we hear wrong perceptions about this robust and easy to access sample type.  It’s time to set the record straight on DNA from saliva once and for all. Are you ready? Here are 8 facts about DNA from saliva that most people don’t know.

All about that base: applications of the fifth base of DNA

Posted by Lisa Gamwell on Tue, May 12, 2015 @ 13:05 PM

Methylated cytosine, also known as “the fifth base of DNA” has attracted a lot of research attention lately due to its importance in controlling gene expression. This fifth base has inspired researchers to study its impact on several diverse fields, such as oncology, neurology, psychology, forensics and even workplace health and safety. Methylated cytosine has even been used as a predictor of biological age [1].In this blog post I’d like to share a few examples of the exciting ways this “extra” base is providing new avenues for research.

Stabilize your sample: A “right from the start” Q&A

Posted by Devin Hale on Wed, Mar 11, 2015 @ 10:03 AM

In an earlier blog post we discussed the importance of reliable samples for human genomics, microbiome and infectious disease nucleic acid based applications, and how a lack of trustworthy samples can not only lead to incorrect outcomes, but also keep you from having full confidence in your results. To obtain a truly accurate outcome, a sample must be stabilized and protected from the point of collection until it is analysed downstream.

Do you know the biggest challenge in genetics?

Posted by Devin Hale on Tue, Jan 27, 2015 @ 10:01 AM

I’m sure you are familiar with the expression “Garbage in, Garbage out”. Popular in the field of computer science, it implies that incorrect or low quality input will result in correspondingly poor output. The mere existence of a result is no guarantee of its quality or accuracy, as surely as cooking with the wrong ingredients will not produce your desired dish.
