Analysis to Next Generation Sequencing Technology

With the development of science, traditional Sanger sequencing has failed to meet new requirements of low cost, high throughput and fast in speed.

Recent years, with the discovery and promotion of second-generation sequencing technology, the gene sequencing speed has increased greatly while achieving a substantial decline in costs, making large-scale application of genome sequencing possible. Now, the cost of personal whole genome sequencing is about 5,000$, and is expected to decreased to less than $ 1,000 in the next few years.

The rapid development of sequencing technology will promote the massive accumulation of DNA sequencing data, accompanied by the accumulation of the corresponding individual diseases, signs and other data at the same time. When we accumulate enough data, how to understand these data will be critical. On the micro level, generations of molecular biologists’ studying the effects of apparent biological traits genes exert on utilizing technologies like gene knockout have made breakthroughs in many crucial aspects. On the macro level, statistics and other data analysis techniques are introduced to study the relationship between gene sequences and biological phenotype. The accumulation of basic scientific research gradually brings breakthroughs in clinical applications.

There are now two types of clinical applications mainly, one aims at disease screening of ordinary people. It infers people’s future risks of getting cancer by measuring the known genes associated with a disease loci. The other aims at the diagnosis cancer and other deadly diseases. It finds in a series of drugs or plans the most effective one for certain patients by testing the loci of certain genes.

Data from BBC research shows that total global gene sequencing market increased from $ 7.941million in 2007 to $ 4.5 billion in 2013, and will reach $ 11.7 billion in the year of 2018 with the CAGR up to 21.2%.

Currently, the market of de novo sequence platform is mainly taken by several major manufacturers, including the Illumina, Ion Torrent / Life Technologies (was the acquisition of Thermo Fisher in 2014), 454 Life Sciences / Roche, etc.

Under such a circumstance, the next generation sequencing technology (second-generation sequencing) appears. As an emerging industry, the next-generation sequencing technology can be applied in clinical testing like antibody discovery, health industry, industrial and agricultural use of gene-oriented study as well as scientific research and development.

Good,, Bad, and Trans Fats and the Health Risk They Pose

What many don’t realise is that fats are essential for good health. The brain, for instance, is contains fat, but it is the good one and not that which can kill you. As people age they become more susceptible to weight gain and the large stomachs seen in many. The fat around their middle is from bad fats that usually come from things like sugar and trans fats.

Alcohol is the same as sugar in its molecular component. In other words, sugar breaks down into the same structure as alcohol and this is why beer drinkers end up with what is described as a ‘beer gut’. But that is not trans fat but the product of a normal digestive function whereby the ‘sugar’ overloads the liver and turns into fat.

In that case one may end up with a fatty liver and possibly pancreas leading to cancer of the organs. It also leads to diabetes and loss of limbs, eye-sight, and heart disease, among other things.

Then there are the trans-fats and these are normal fats that have undergone transformation due to heat. They take on extra molecules of hydrogen during the process and that makes them virtually indigestible by the liver so that they are laid around the vital organs.

The worst practice comes from super heated and oft heated oils. They are found in commercial ovens where deep fried fish and vegetables are produced. They are the in many of the snack foods people are addicted to while the warning that should accompany them is that they can lead to diseases, as described above, and even death.

A Healthy Dose of Medicine for the Soul

A large segment of the human population takes things way too seriously for their own good. The strange anomaly is that most people laugh at the wrong thing and fail to laugh at the right thing. This serious incongruity has robbed people of a healthy attitude towards life in general.

Those who take life too seriously are in danger of missing the great joys of living in a crazy world like ours. I am not sure about the scientific research but I would guess that for every sad moment it takes one hundred laughs to balance the books. Some people are about ninety-nine laughs short of a real sane moment.

I like the old English proverb that says, “Laugh and the whole world laughs with you, cry and you cry alone.”

From my perspective, if you cannot laugh with someone you will not be able to cry with him or her and have it mean anything.

According to some medical advice, it takes more facial muscles and energy to frown than it does to smile. Of course, the only exercise some people have is frowning and who am I to take that away from them.

I am determined, no matter what, to exercise my right to smile and laugh and enjoy the world around me. I must confess that I get this attitude quite honestly.

My paternal grandfather was a Past Master in the area of practical jokes. No amount of time was too much to spend preparing for one of his famous practical jokes. His favorite holiday was April 1 and began preparing for this holiday right after Christmas.

The fact that his practical jokes at times got him into trouble did not seem to affect him at all.

Once while in the hospital for an extended period he had somebody smuggle in to him a can of snuff. For some reason he liked chewing snuff. It is the most disgusting habit I know of on earth.

He no sooner received his smuggled goods then he began chewing it. If you know anything about chewing snuff, you know it is accompanied by a lot of spitting. As usual, his timing was impeccable. Just as the head nurse passed his door and looked in, he leaned over and spit in to the garbage can he had next to his bed. The nurse, not knowing about the chewing snuff, thought he was spitting blood and immediately went into emergency mode. Immediately my grandfather was rushed into the operating room and the surgeon and medical team were assembled.

My grandfather was very sick at the time. Some did not think he would get out of the hospital.

Just as they got him situated in the operating room he pulled from under his sheet his can of chewing snuff and smiled at them. The only person in the room that thought this was in any way amusing was my grandfather. The doctors were so angry with him that they refused to see him for three days and confiscated his can of chewing snuff.

My aunt and uncle lived right next to my grandfather. My aunt was hyper clean when it came to her house. Dirt in any form was not welcome under her roof. She had a broom that was always within reach because she never knew when a piece of dirt would try to invade her domicile.

That year my grandfather found something new. I am not sure where he found it but he probably spent a lot of time looking for something like this. It was a rubber facsimile of a very nasty looking piece of vomit. To him it was a prized possession.

Most of his practical jokes were executed on April 1. Whenever we saw grandfather coming on this particular day we usually ran for cover.

He went over to visit my aunt and was sitting on the couch in the living room. They chatted for a little while and then my grandfather began to cough a little bit. He said to my aunt, “I haven’t been feeling good lately. I really don’t know what it is.” Then he started to cough a little more seriously, to which, my aunt got up and went to the kitchen to get him a glass of water thinking that might help him.

When she got back, she was shocked to see on her new coffee table a very horrible sight. My grandfather was bent over the coffee table hacking and coughing as though he was in the process of dying. On the coffee table was a very nasty looking piece of vomit.

My aunt went into hysterics. She whirled around and within a moment had grabbed her broom and started towards my grandfather. My grandfather was laughing but not for long.

Suddenly he realized that the flailing broom in my aunt’s hand was aimed at him. She chased him out of the house, down the driveway and for at least three blocks yelling obscenities at him that I dare not repeat in public society.
