AD: Shocked! The peak value of plasma Aβ42/Aβ40 began to decline 41 years before the deposition of brain Aβ!

 AD: Shocked! The peak value of plasma Aβ42/Aβ40 began to decline 41 years before the deposition of brain Aβ! Alzheimer's diseases: New discovery on plasma Aβ42/Aβ40.  AD: Shocked! The peak value of plasma Aβ42/Aβ40 began to decline 41 years before the deposition of brain Aβ! Amyloid β (Aβ) plaque deposition and phosphorylated tau (p-tau) protein tangles are two important pathological features of Alzheimer's disease (AD), and there are many kinds of AD biomarkers derived around them, Knowledge of the longitudinal trajectories of key markers could not only help improve the selection and monitoring of participants in clinical trials, but also help identify those at high risk for neurodegenerative changes and cognitive impairment.   Although research on AD biomarkers has increased substantially in recent years, research on longitudinal changes in biomarkers is relatively limited. Studies have shown that the levels of plasma Aβ 42 /Aβ 40 , p-tau181 and glial fibrillary acidic...

4 US states have suspended Johnson & Johnson COVID-19 vaccine

4 US states have suspended Johnson & Johnson COVID-19 vaccine



Georgia, in the United States, announced the temporary closure and suspension of vaccination sites in the state after it was revealed that 8 people had adverse side effects due to Johnson & Johnson vaccination. This became the fourth state in the United States to suspend Johnson & Johnson vaccination .


So far, Johnson & Johnson's new coronavirus vaccine has been suspended in Colorado, North Carolina, Iowa, and Georgia for serious side effects.





Last week, 18 people in North Carolina reported side effects after receiving the Johnson & Johnson vaccine, while 11 people in Colorado responded to the vaccine with symptoms including dizziness, nausea and fainting.


Public health officials in Colorado, Georgia, and North Carolina reported that most of the negative reactions to Johnson's vaccine occurred within 15 minutes of vaccination; a total of seven people were taken to the hospital for observation.


Starting today, more injection sites and people suffering from adverse reactions or hospitalizations caused more Johnson & Johnson vaccine clinics to close



The frequent occurrence of serious adverse reactions caused by Johnson & Johnson vaccine has led to an emergency suspension in Europe.



The Australian government temporarily refuses to use Johnson & Johnson's COVID-19 vaccine





The Johnson & Johnson vaccine is currently mainly used in the United States. Although the vaccine has been approved for use in the European Union, it has not yet started.


On April 7 at the Johnson & Johnson vaccination station in Cumming Playground, Georgia, eight people felt dizzy after the injection, but local health officials believed that this might be due to the hot weather.


Dave Palmer, a spokesperson for the North Georgia Department of Health, told the media that the person who had the adverse reaction fainted. We think this has nothing to do with vaccines. This may be caused by more environmental factors.

It has been reported that less than 2% of the 435 people who were vaccinated on the spot had adverse reactions.


At the open site, Johnson & Johnson can be vaccinated, and the vaccination does not require an appointment, so come and fight. As a result, almost no one comes



Johnson & Johnson's vaccine has been in a state of affairs since its development, and during the period there was also pollution in the production process.


After the vaccine was injected, it was reported that serious side effects were hospitalized and many cases were infected with the new crown.


A 52-year-old healthy man in New Jersey who was vaccinated by Johnson & Johnson unfortunately contracted the new crown and had to be hospitalized



Richard Tyrrell of Gokland County (WRIC), Virginia, received a dose of Johnson & Johnson's vaccine earlier this month and developed a severe rash


The rash was spread all over the body and the skin turned red. The 74-year-old man was admitted to the hospital and stayed in the VCU Medical Center for 5 days.




At the same time, the Johnson & Johnson vaccine, three weeks after vaccination, the Brooklyn woman in New York was infected with the new crown.



Ashley Allen, 31, received the Johnson & Johnson vaccine on March 10 and was one of the first vaccinations in New York. After being vaccinated at 2 a.m. that day, Allen had a brief fever, but the side effects symptoms quickly disappeared. Wear masks and wash hands frequently.


She started to feel an itchy throat on March 31, and later developed dry cough symptoms. At first, she thought it was an allergy, but as the situation worsened, she suspected that she had Lyme disease (Lyme disease). During the period between April 4th and 5th, two rapid tests were initially shown to be infected with new coronary pneumonia, and the diagnosis was confirmed by PCR nucleic acid testing.


After Allen revealed that he had been vaccinated, the staff was shocked.


Kris Bungay, a primary care physician in Manhattan, said that vaccines may not prevent people from getting infected, but they can reduce the risk of hospitalization or death. Allen's case further shows that after vaccination, we still need to be careful and continue to maintain epidemic prevention measures.


Another more serious problem for Johnson & Johnson is distribution.


Starting next week, the company has drastically cut 86% of state shipments.


This is because workers at a manufacturing plant in Maryland accidentally mixed up the ingredients of the vaccine last month and damaged 15 million doses of the vaccine. Therefore, Johnson & Johnson must recall 62 million doses of vaccines to confirm whether they are contaminated.


According to data from the US Centers for Disease Control and Prevention (CDC), Johnson & Johnson's single-dose vaccine protection rate is 66%.


European regulators are investigating whether vaccines from Johnson & Johnson and AstraZeneca caused abnormal blood clots.


Johnson & Johnson also stated that it is working closely with experts and regulators to evaluate the data.


The three major US vaccines, Pfizer, Moderna, and Johnson & Johnson, all produced adverse reactions among more than 60,000 people across the country.


For each manufacturer, only 0.1% of people report side effects.


Every vaccine currently in the United States currently has side effects, which will start to appear in about 4-5 hours. Usually headache, low-grade fever, muscle aches, etc.


But this time the Johnson & Johnson vaccine was discontinued mainly because the patients began to develop side effects during the 15-minute observation period after the injection. This abnormality prompted the four states to stop the vaccination.


Fauci is here again. He said today: Americans who have been vaccinated cannot eat indoors either.



The big Vs called out one after another and said that this was too ridiculous, too stupid, and quickly dismissed him.


And the Pfizer vaccine, which has always been sought after, also comes with bad news!


An Israeli real-time data study found that the coronavirus variants found in South Africa may evade the protection provided by Pfizer vaccine to some extent.


The researchers found that compared with the original coronavirus and the British variant, the vaccine is less effective against the South African variant, which has covered almost all COVID-19 cases in Israel.


A study by Tel Aviv University and Clalit, Israel's largest healthcare provider, found that the South African variant B.1.351 accounted for about 1% of all COVID-19 cases in all study populations.


However, in patients who received two doses of the vaccine, the prevalence of the variant virus was 8 times that of unvaccinated people, at 5.4% and 0.7%, respectively.


This means that the South African variant may break through the protection of Pfizer vaccine!


The researchers said that compared with the original coronavirus and the British variant, the vaccine is less effective against the South African variant, which has covered almost all COVID-19 cases in Israel.


This study is not intended to infer the overall vaccine efficacy against any variant, as it only studies people who have tested positive for COVID-19, not the overall infection rate.


Pfizer declined to comment on the Israeli research.
