Dirty Water Destroys People – Part 3 of 3
We also measured groundwater at two sites that had very little natural gas drilling and had no drilling”. The flood samples from sites with known spills contained moderate to high levels of hormone-disrupting chemicals compared to samples taken from sites located away from fracking, the researchers found. They also found run levels of the chemicals in samples taken from the Colorado River.
So “If you count up all the types of activity, our sites had on average double the activity relative to our control sites. Nagel said she hopes this check out raises a red flag for people who live near fracking operations. “We found more endocrine-disrupting activity in the water close to drilling locations that had experienced spills than at comparison sites,” she said in the flash release. “This could raise the risk of reproductive, metabolic, neurological and other diseases, especially in children who are exposed to endocrine-disrupting chemicals” neosizeplus men. Although the study found a potential risk of hormonal disruption from living near fracking operations, it did not be shown a cause-and-effect relationship.

He said the researchers grossly overestimated the enumerate of chemicals used in the process. “Activists promote a lot of bad science and shoddy research, but this study – if you can even command it that – may be the worst yet. From falsely characterizing the US regulatory environment to flat out making stuff up about the additives used in hydraulic fracturing, it’s hard to see how experiment with like this is helpful. Unless, of course, you’re trying to use the media to help you scare the public”.
In conducting the study, the researchers took a two-pronged approach. First, Nagel and her colleagues calculated 12 fracking chemicals in the laboratory to determine whether they could disrupt male or female hormone function. They purchased the chemicals from a supply company and then exposed human cell cultures to the chemicals. The researchers observed the rejoinder of receptors for male hormones (androgens) such as testosterone and the female hormone estrogen.
So “We found that 11 of those 12 (chemicals) disrupt either the estrogen or the androgen receptor,” Nagel said in an interview. The researchers then went out into the field, taking inundate samples from Garfield County, Colo, an area with more than 10000 active wells. “We went to five sites that have experienced some kidney of accident or spill related to natural gas fracking, and measured surface and groundwater.

Dirty Water Destroys People. Groundwater and face water samples taken near fracking operations in Colorado contained chemicals that can disrupt male and female hormones, researchers say. These chemicals, which are employed in the fracking process, also were present in samples taken from the Colorado River, which serves as the drainage basin for the region, according to the study, which was published online Dec 16, 2013 in the roll Endocrinology. “More than 700 chemicals are used in the fracking process, and many of them disturb hormone function,” study co-author Susan Nagel, an assistant professor at the University of Missouri School of Medicine, said in a register news release.
And “With fracking on the rise, populations may face greater health risks from increased endocrine-disrupting chemical exposure”. Exposure to these chemicals can burgeon cancer risk and hamper reproduction by decreasing female fertility and the quality and quantity of sperm, the researchers said. Hydraulic fracturing, also called fracking, is a controversial process that involves pumping water, sand and chemicals into underground at high pressure.
The purpose is to crack open hydrocarbon-rich shale and extract natural gas. Previous studies have raised concerns that such drilling techniques could persuade to contamination of drinking water. The oil and gas industries strongly disputed this new study, noting that the researchers took their samples from fracking sites where unwitting spills had occurred. Steve Everley, a spokesman for industry group Energy in Depth, also disputed claims in the research that fracking is exempt from the federal Safe Drinking Water Act and the Clean Water Act.

What’s next? “By insight how typists are so good at typing, it will help us train people in other kinds of skills, developing this autopilot controlled by a pilot typist”. Gregory Hickok, director of the Center for Cognitive Neuroscience at the University of California at Irvine, said such explore can indeed lead to advances.
Simply reaching for a cup is a fairly complicated process who’s familiar with the study findings. “Despite all that is flourishing on, our movements are usually effortless, rapid, and fluid even in the face of unexpected changes additional reading. If we can understand how humans can achieve this, we might be able to build robots to do all sorts of things, or realize the potential new therapies or build prosthetic devices for people who have lost their motor abilities due to disease or injury”.

In particular, Logan and colleagues wondered about complex things that we do on autopilot without much conscious thought. “If I decide I want to go to the mailroom, my feet read me down the hall and up the steps. I don’t have to think very much about doing it. But if you look at what my feet are doing, they’re doing a complex series of actions every second”.
Enter the typists. “Think about what’s twisted in typing: They use eight fingers and probably a thumb. They’re going at this rate for protracted periods of time. It’s a complex act of coordination to carry out typing like this, but we do it without assessment about it”.
The researchers report their findings in the Oct 29, 2010 issue of the journal Science. The research suggests that “the motor system is taking care of the keystrokes, but it’s being driven by this higher-level scheme that thinks in terms of words and tells your hands which words to type”. Two autonomous feedback loops are involved in this error-detection and correction process, the researchers said.

Error Correction System Of The Human Brain Makes It Possible To Develop New Prostheses. A altered study provides perceptiveness into the brain’s ability to detect and correct errors, such as typos, even when someone is working on “autopilot”. Researchers had three groups of 24 skilled typists use a computer keyboard. Without the typists’ knowledge, the researchers either inserted typographical errors or removed them from the typed printed matter on the screen.
They discovered that the typists’ brains realized they’d made typos even if the screen suggested otherwise and they didn’t consciously clear the errors weren’t theirs, even accepting responsibility for them. “Your fingers notice that they make an error and they slow down, whether we corrected the error or not,” said study lead prime mover Gordon D Logan, a professor of psychology at Vanderbilt University in Nashville, Tenn.
The idea of the study is to understand how the brain and body interact with the environment and break down the process of automatic behavior. “If I want to initiate up my coffee cup, I have a goal in mind that leads me to look at it, leads my arm to reach toward it and drink it. This involves a kind of feedback loop. We want to manner at more complex actions than that”.

And “Patients have to get used to it, and most patients do,” said Lee-Chiong, who is also a professor of medicine at National Jewish Health at the University of Colorado Denver. The well-built of the device is akin to a fan and can be lessened by placing the device under the bed or using earplugs. The cost of CPAP machines vary but can move from a few hundred dollars to $1000, Lee-Chiong said.
CPAP is covered by most insurance, including Medicare. For the study, Martinez-Garcia and colleagues randomly assigned 194 patients with sleep apnea and far up blood pressure to CPAP or no CPAP. During the study the patients continued to take their blood pressure medications. The researchers found that those receiving CPAP lowered their 24-hour average blood lean on 3,1 mm Hg more than those not receiving CPAP.
In addition, those treated with CPAP had a 3,2 mm Hg greater reduction in 24-hour average diastolic blood pressure.The contrast in systolic pressure wasn’t statistically significant between the two treatment groups, the researchers noted.Over the 12 weeks of the study, about 36 percent of those receiving CPAP had at least a 10 percent forsake in nighttime blood pressure, compared with 22 percent of patients not receiving CPAP. The systolic pressure, the top number, measures the pressure in the arteries when the heart beats blood cencar ka elaaj. The diastolic pressure, the bottom number, measures the weight in the arteries between beats.
