(Natural News)
Many older people don’t seem as mentally sharp as young people, and it’s long been believed that brains stop making new cells as they age. Some research has even indicated that adults do not grow new neurons. Now, a new study in the journal Cell Stem Cell casts these ideas in serious doubt as researchers show elderly people are more intact both cognitively and emotionally than scientists once believed.

The researchers made their conclusions after examining the hippocampi taken from 28 people between the ages of 14 and 79 who had been healthy but died suddenly. Those involved were people who had not been drug users or cognitively impaired in any way, nor had they suffered from depression or been taking antidepressants for any reason – something that can affect new brain cell production.

This study broke ground as it marked the first time scientists studied the state of blood vessels and newly formed neurons throughout the human hippocampus so soon after the subjects passed away. The hippocampus serves many functions, one of which is creating new memories and emotional control. The brains came from donations, and all had been preserved with the same methods and came with detailed medical histories.

The researchers discovered that all of the brains, even the oldest ones in the study, produced new brain cells. In fact, people in their 70s create new brain cells at a rate that is comparable to that seen in teenagers’ brains, according to the scientists.

However, they found that older people form fewer new blood vessels in their brain structures and have a smaller pool of stem cell descendants known as progenitor cells. It is this declining availability of neural stem cells and the drop in vascularization and cell-to-cell connectivity inside the hippocampus that could be responsible for the lower cognitive-emotional intelligence seen among some older people. They’d like to carry out further research on aging brains to determine how the proliferation, survival and maturation of neural cells is regulated by inter-cellular pathways, transcription factors, and hormones.

The study’s lead author, neurobiologist Dr. Maura Boldrini of Columbia University, said: “When I went to medical school, they used to teach us that the brain stops making new cells.” However, researchers started to doubt that notion after observing older mice producing new nerve cells and early studies on humans showing a similar trend.

Another recent study reached a far different conclusion

The findings come just a month after the journal Nature published a study in which researchers from the University of California, San Francisco, were unable to find evidence that neurogenesis takes place in humans after they’ve passed adolescence.

That group said that while the newer study’s findings about the reduced blood vessel growth in adults was interesting, they did not think that there was any conclusive proof that neurogenesis does occur in adults. However, the two studies worked with very different samples, so it isn’t that much of a stretch for their findings to be so conflicting.

Boldrini pointed out: “In science, the absence of evidence is not evidence of absence. If you can’t find something it doesn’t mean that it is not there 100 percent.”

While scientists now have some very interesting new findings to ponder, it looks like the debate about whether or not the brain continues to create new neurons throughout our lifetime is far from settled.

State Moved Teen to Adult Prison From Juvi Where He Was Raped and Infected With HIV-Lawsuit


Baton Rouge, LA — (RT) A Louisiana sheriff and two jail staff have been hit with a federal lawsuit after a teen inmate was moved away from the juvenile unit and subsequently raped by an adult cellmate who infected him with HIV.

The lawsuit, filed Monday, accuses East Baton Rouge Parish Sheriff Sid Gautreaux, prison warden Dennis Grimes, and a corrections officer by the name of Deputy Daniels of violating the teen’s constitutional rights.

The suit states that the teen met the criteria of being a “high risk sexual victim” under the federal Prison Rape Elimination Act and should have remained segregated from the jail’s general population. He was 5’10” and 125 pounds at the time of the incident and “mildly physical handicapped due to Fetal Alcohol Syndrome suffered as a child.”

Instead, the suit says the 17-year-old was transferred away from the jail’s juvenile wing and into the cell of a man who is awaiting trial on charges that he raped a woman in 2015. He is also charged with battery and burglary, local CBS affiliate WAFB reported.

On February 16, 2017, the teen was reportedly awakened by the rape and was threatened to not speak about the incident. He managed to alert jail staff by giving a deputy a note. As a result, he was separated from the cellmate and taken to the facility’s infirmary.

The young inmate suffered a fractured bone during the incident and was treated at a local hospital. He was given anti-HIV medication, and the hospital told him to follow up in six months to test if he was infected. According to the suit, the sheriff’s office did not follow up on the teen’s six-month check-up. He was ultimately diagnosed as being HIV-positive in December.

The suit states that the prison warden and corrections officer should have never placed a “high risk sexual victim” in a cell with an inmate who had been considered a high-risk sexual predator by the warden’s staff. It also says the warden should have known about the inmate’s HIV status and isolated him from the rest of the prison’s population.

The suit is seeking compensatory damages against each of the three defendants, along with attorney’s fees and punitive damages against the victim’s cellmate and the corrections officer.

Cops Mistake Small Teen Girl for Large Adult Male, Beat & Sic K9 on Her


Bakersfield, CA – Tatyana Hargrove, 19, was recently assaulted by police because she was mistaken for a large man who was seen carrying a machete. Hargrove in no way matched the description of the criminal that the police were after, but they singled her out anyway, as she made her way home from a local store.

According to Hargrove, on June 18th she had walked to the nearby Wooden Nickel Trading Company on Ming Avenue to buy her father a present for father’s day. However, she found that the store was closed when she arrived. Hargrove decided to go back home but on her way, she stopped for a drink from her water bottle since it was a very hot day.

That was when police swarmed around her with guns drawn, asking her what was in her bag. When she asked them why they wanted to search her and demanded a warrant, they became aggressive and threatened her with a dog. She handed over the bag, which had nothing illegal in it, and yet the police punched her in the mouth, allowed the police dog to bite her, and then arrested her.

Hargrove told reporters, “He put his other knee on my head, and I told him, ‘I can’t breathe, I can’t breathe’ and I started yelling out ‘Somebody help me, somebody help me, they’re going to kill me.’”

To make matters worse, after cops beat her and allowed their dog to maul her, she was charged with suspicion of resisting or delaying an officer and aggravated assault on an officer.

However, in a phone call with the family, the police admitted that this was a case of mistaken identity. Additionally, arresting officer Christopher Moore said in the police report that he didn’t know Hargrove was a woman until after he had arrested her.

The person who police were actually after that day was a man named Douglas Washington. Washington was described as a bald man who was nearly 6 feet and 170 pounds. He was last seen wearing a white T shirt, dark jeans and a pink or red backpack. The man was reportedly wielding a machete and threatening several people in the same area of the store that Hargrove had visited.

Conversely, Hargrove is a young female that is just over 5 feet and roughly 115 pounds. She was wearing a white shirt, blue jean shorts and a black hat with a red backpack.

“She appeared to be a male and matched the description of the suspect that had brandished the machete and was also within the same complex the suspect had fled to,” Moore said in the police report.

Moore went on to claim that she attempted to flee and push the police. Moore claimed that he believed the whole time that she had a machete in her bookbag, which is why he said he believed he was justified in using such an excessive show of force.

The Bakersfield police have refused to make a formal statment on the incent. However, BPD Sgt. Ryan Kroeker did tell reporters that criminal charges have been filed against Hargrove and that they dont believe that the officers used excesive force. The department will not even be launching an internal investigation into the actions of the officers involved.

NAACP Bakersfield chapter President Patrick Jackson made a statement on behalf of Hargrove saying that the family believes she was wrongly targeted and should not have any charges against her.

“It’s becoming more and more of a pattern. She’s never been in trouble before, and all of a sudden you’re a heinous criminal in two seconds,” Jackson said.

This common adult beverage has sent more people to the hospital than heart attacks

Image: This common adult beverage has sent more people to the hospital than heart attacks

(Natural News)
A report released on Thursday, June 22 by the Canadian Institute for Health Information (CIHI) showed that 212 people each day in the years 2015 to 2016 — or about 77,000 admissions — had been treated in Canadian hospitals for alcohol poisoning, alcohol withdrawal, liver disease, alcohol abuse, and other conditions that are “100 percent caused by the harmful consumption of alcohol”. This meant that more people were hospitalized due to alcohol-related reasons than heart issues such as heart attacks. This number did not include people who were treated in an emergency room and released.

Excessive drinking has been known to cause serious diseases such as pancreatitis, liver cirrhosis, diabetes, and cardiovascular disease. In severe cases, it has been known to cause death. According to a study by the Institute of Health Metrics and Evaluation as cited by CIHI, there were 5,082 alcohol-related fatalities in Canada in 2015. (Related: Drinking Alcohol Raises Breast Cancer Risk as Much as Smoking Cigarettes.)

The Public Health Agency of Canada has stated that excessive alcohol consumption is the leading cause of injury in Canada, as it leads to instances of impaired driving.

Alcohol-related sicknesses cost to Canada’s health care system

In the years 2014 to 2015, the average hospitalization cost of people who were confined due to alcohol consumption reasons reached $8,100, higher than the average hospital stay for other causes, which was $5,800. This is because people who were hospitalized due to alcohol consumption reasons stayed longer in the hospital (approximately 11 days ) as compared with people who got hospitalized due to other reasons (seven days).

Alcohol-related hospitalizations occurred more frequently in territories than in provinces, and more in the west than in the east, with the exception of Nova Scotia.

Alcohol-related hospitalizations in Ontario, the North West local health integration networks (LHIN), which includes Thunder Bay, were estimated at 603 hospitalizations per 100,000 people, which is more than twice the national average. The North West Territories hospitalization rates for alcohol took the cake at 1,315 hospitalizations per 100,000 people – making it the highest rate for alcohol-related hospitalizations in the country.

In the Champlain region, including Ottawa, alcohol-related hospitalizations fell below the national average, but were higher than the Toronto and Mississauga regions. In 2014 to 2015, there were 166,000 hospitalizations per 100,000 individuals in Champlain as compared with the national average of 239.

Canadian Population Health Initiative at CIHI director Jean Harvey said one of the main reasons why alcohol-related death, injuries, or diseases were so prevalent in Canadian society was because alcohol consumption is ingrained in the culture; as a matter of fact, 80 percent of people in Canada are allowed to drink.

According to CIHI, the difference in the rates of alcohol-related diseases and injuries was due to different “alcohol policy landscapes” across Canada.

In addition, pricing controls factor in to this equation. Some regions set minimum prices for items at retail, others have minimum prices at bars and restaurants, and others index the price of alcohol to inflation or alcohol content.

“For us, those differences represent opportunities for potential improvement. Measuring this, and monitoring these rates can help us identify whether the policies and approaches are effective in reducing alcohol harm,” Geoff Hynes, manager of the Canadian Population Health Initiative for CIHI, said.

Hynes added that pricing is “one of the most effective and cost-effective ways to reduce alcohol harm, population-wide”.

According to a report released last year by Ottawa Public Health entitled Let’s Continue the Conversation, it is more likely for men over the age of 20 to be hospitalized for drinking alcohol drinking than for women in the same age group. However, among children between the ages of 10 and 19, girls are more likely to be hospitalized for alcohol consumption than boys.
