Niet alleen dat, tandrot komt ook in de bloedbaan terecht en veroorzaakt tal van andere ziektes.

Het zou me niets verbazen wanneer deze vinding neergesabeld gaat worden vanwege de belangen, of we er gewoonweg niet meer van vernemen.

Het is bv ook al sinds de jaren 60 bekend dat psylliumvezels perfect helpen bij overgewicht (zie juso psylliumvezels), maar dat is bewust nooit aan de grote klok gehangen omdat er miljarden omgaan in de afslankindustrie, heden zijn maagverkleiningen booming business.

Wat? Medicijnen voor malaria en ebola zijn volgens mij ook Chinezen voor verantwoordelijk. Ze botsen wel tegen steeds meer racisme aan in de VS met de alsmaar toenemende Sinophobia daar. China moet haar wetenschappelijke infrastructuur verbeteren zodat ze niet hoeven te verkassen naar de VS voor hun ambities.

Je kunt ze zowel bij verstopping als bij diarree gebruiken, ze zorgen nl voor een normale stoelgang (soft bulk), en zijn zeker niet laxerend.

Het is supergezond.

Psylliumvezels worden gebruikt bij zowel obstipatie als bij diarree. De vezels hebben de eigenschap dat ze veel vocht kunnen binden, dit zorgt voor een beter gevormde stoelgang.

Psylliumvezels ondersteunen de darmfunctie, beschermen de darmwand en gaan zowel constipatie als diarree tegen. Daarnaast helpen psylliumvezels bij het verlagen van de cholesterolspiegel door cholesterolbinding en het stimuleren van galzoutvorming. De vezels ondersteunen een normale bloedglucosespiegel door een meer geleidelijke opname van suikers uit het voedsel en bevorderen de uitscheiding van gifstoffen met de ontlasting. Psylliumvezels passen uitstekend in een reinigingsprogramma.

Maw, geen laxeermiddel, wel gebrek aan kennis hierover bij de consument.

Chinese Scientists Edit DNA in Attempt to Cure Man’s Cancer, HIV

Chinese researchers safely treated a man with leukemia and HIV using gene-edited stem cells, a step forward in a field that was shaken last year when another Chinese scientist used the same technology to create the world’s first genetically-edited babies.

The man’s medical case, published Wednesday in the New England Journal of Medicine, is the first detailed report in a major academic journal of how doctors are using the experimental tool Crispr to manipulate the DNA of a living patient in an effort to cure disease. But even before the earlier controversy in China, there’s been a heavy note of caution in the field about how far and fast to proceed with the technology.

The patient’s dual diseases -- HIV and cancer -- gave researchers at the Peking University Stem Cell Research Center in Beijing an opening. The man needed a transplant of stem cells to replace the damaged ones that were causing his blood cancer. That procedure also gave them the opportunity to re-engineer a gene called CCR5 in the donor cells to be resistant to HIV.

“This is a green light for the whole field of gene editing,” Carl June, a pioneer in the use of gene therapy to treat cancer and HIV at the University of Pennsylvania, said in an interview. He published a companion piece in the journal.

Earlier Controversy
The work has some parallels to the highly controversial effort by scientist He Jiankui to alter the DNA in two embryos to make the babies resistant to HIV. That effort sparked an international backlash and calls to put a moratorium on using Crispr to create permanent changes in a subject’s DNA, especially in an embryo. The latest effort is a far more incremental but legitimate effort, especially given the imprimatur of one of the world’s foremost academic journals.

The work by Peking University’s Hongkui Deng and colleagues had several key differences from the earlier effort, including the controlled use of gene-editing on only select cells, the patient’s consent and the subsequent publication of the findings.

The experiment had mixed results. Nineteen months after the treatment, the young man’s cancer, an acute lymphoblastic leukemia, is in remission, and the modified cells integrated into his body and remain. The attempt to cure his HIV was a failure: Only about 5% of his infection-fighting lymphocytes are now resistant to HIV, making continued treatment of the virus necessary.

Even so, the results show a key proof of the concept that Crispr-edited cells can be transplanted into a person and persist long-term, Deng said in an emailed response to questions.

“We should all hope that this is a significant and powerful advance in scientific research, for if it can be tested safely and ethically -- and it surely can -- it could transform medicine,” said Laurie Zoloth, a professor of religion and ethics at the University of Chicago. “The first published paper is quite an historical moment.”

Safety Watch
The researchers didn’t detect any adverse events from the gene-editing or signs that the man’s DNA had been damaged. Larger studies where more altered cells persist are needed to confirm the findings, Deng said. Concerns over unknown potential effects of Crispr has been one of the major hurdles standing in the way of more trials moving forward.

“If they had gone the other way, with a lot of off-target hits, that would have been chilling for the technology,” June said.

Data on three patients treated with Crispr-manipulated cells at the University of Pennsylvania, perhaps the first in the U.S., will be presented at the American Society of Hematology meeting in December.

Crispr has been compared to a word-processing system that allows writers to easily cut out extraneous words and correct typos. With DNA, it acts like molecular scissors, precisely trimming specific flaws in genes. Scientists are still trying to determine if tinkering with the genome can create stray errors elsewhere or lead to unexpected harms, such as cancers caused by uncontrolled cell growth.

There’s a biological rationale for targeting HIV in a leukemia patient, in part because of a handful of people cured of HIV who had bone-marrow transplants. Timothy Ray Brown became the first adult ever to be cured of HIV in 2007 after he received a bone marrow transplant to treat his leukemia. The donor cells had a rare mutation in the CCR5 gene, found in about 1 in 20 people, that makes it difficult for HIV to infect cells. Brown was known as the “Berlin patient,” and other researchers have tried to replicate his experience.

Researchers are now planning to try to increase the number of cells that are transformed and can thrive inside of a patient, Deng said. Other diseases with genetic causes, such as sickle cell anemia, muscular dystrophy, cystic fibrosis and cancer are likely to see a surge in interest based on the new results.

“Crispr technology is so flexible it can be used for all types of conditions,” June said. “You can rewrite the genetic code at will.”

But the China study also showed some of Crispr’s limits because only about 5% of the cells were affected, said Zoloth, the University of Chicago professor.

“This thoughtful honesty and modesty in scientific claims are an important part” of the project, Zoloth said. “It is a first step, if tentative, toward engineering naturally occurring constructs in nature in ways that benefit humanity.”

More Research
Leaders in the field agreed the safety findings are a critical first step, though they are hoping further refinement of the process will lead to better results. One key issue is that cells that have been altered using gene-editing or other types of technology are “finicky and tricky to transplant,” said Jennifer Doudna, professor of biochemistry and molecular biology at the University of California, Berkeley, who is credited as an inventor of Crispr.

“This plants the flag to say that at least in this one instance, this type of therapy appears safe,” she said. “The next step is showing that there is some efficacy, a therapeutic benefit to doing this.”

While the NEJM report is the first publication about the use of Crispr in humans, other pioneering researchers have been using it for years in China. The first trials started in 2016, when Lu You, a physician at Sichuan University, put gene-edited cells into a lung-cancer patient. Since then, scientists have launched multiple trials and reportedly treated dozens of patients. But little is known about some of those studies, and medical research is not as stringently regulated in China as it is in the West, prompting concerns about their safety and ethics.

“In the next 18 to 24 months, we’ll start to see published results from a number of these ongoing trials,” Doudna said. “That’s where the rubber hits the road. Does it benefit patients? Time will tell.”

China's Foreign Minister criticizes Canadian reporter for her question

quote:

Is there a real western media bias against China as claimed by so many, particularly mainland Chinese?

Guillermo Arturo Gastélum, lived in Shanghai (2015-2019)
Answered Thu

Most definitely yes. Take it from a Westerner that knows both sides of the story.

I just moved from Shanghai to Lille, France with my girlfriend (Russian girl). I spent 4 years living in Shanghai and I can tell you that, so far, those have been the best years of my life.

Now that I’m back to the West, I have a compelling narrative to tell whenever people ask me:

“What were you doing before starting the Master degree? Were you working in Mexico?”

To which I reply

“Nope! I was living in China for the past 4 years.” (very proud of my unique story)

The initial reaction is surprise, of course. Most Western people can’t fathom the idea of moving to China and think it is such a big deal (it is not).

Then, the comments come. Some people start by asking if I liked the country, if the food was okay, if Chinese people were strange.

Before long, the conversation becomes political.

“But the government there is so bad!”

“But what about the lack of freedom over there?”

“But how could you like it? It’s such a dictatorship!”

Indeed, they cannot believe that I found China to be amazing, convenient and safe.

Btw, similar comments are made about Russia. The one thing that all these Westerners have in common is that they have never been to China nor Russia. And it shows. They wouldn’t be asking these questions had they visited either country. But well, let’s focus on China…

You see, the West loves talking about Chinese propaganda and brainwashing. They believe Chinese people are living under constant oppression and being fed lies about the outside world.

I can tell you, despite all the Western propaganda machine against China, most Chinese people I met have very positive opinions about the West, including the US (despite the trade war). You do not hear them spewing warmongering and hatred or otherwise ill-informed assumptions.

There are many Chinese students studying with me here in France. One common complaint that they have is that people in the West constantly criticize the Chinese government. They are surprised about the harsh comments made by Westerners about China. Nope, they do not like it.

For sure, the CCP has its own propaganda going on around the country. But you know what? It seems to be very pathetic compared to Western propaganda. That one is downright scary and it has really reached brainwashing levels.

Do note that it’s been less than a month since I moved to France and both my girlfriend and I have been asked a lot of these questions about China. Do note that these questions have been asked by many Westerners and not only French people, so it is not a France-only problem.

I fucking love France. I prefer Western way of life, overall. But the whole The-West-Is-Better propaganda has gone too far. The West is pretty cool but stop believing it has some sort of moral superiority just because… democracy?

And most Chinese people are very apolitical, so do not bother them with your “China is bad” narrative.

Rant over.
