10 seconds can reduce the infectivity of covi! Japanese research on drinking this "drink" is right
The Japanese business journal "PRESIDENT Online" reported that scholars from Osaka University, Osaka Prefectural University and Mitsui Agriculture and Forestry started research on the "antiviral activity of black tea" in 2020. Their study shows that polyphenol in black tea reduces the infectivity of influenza viruses, both of which are viruses with an "envelope structure", whether it is the covi or the influenza virus. In the study, scholars took "20 different tea types of polyphenol aqueous solution", "green tea powder solution", "black tea powder solution", "4 types of black tea tea bag extracts" to investigate the effects of covi under a certain period of time and find out how each tea works with its antiviral activity.

Low concentrations of green tea and black tea reduce infection
Surprisingly, the "polyphenol aqueous solution of 20 different tea species" could not reduce the infectivity of the virus, but low concentrations of green tea and black tea can effectively reduce the infection. In terms of polyphenols, other teas contain several types of polyphenols, so they can be very potent. This principle is the same as that of Kampo herbs.
Compared with refined products, it is better to eat pure natural products directly.

Only "black tea powder solution" and "black tea tea bag extract" can reduce risk of covi infection
Although "green tea powder solution", "black tea powder solution" and "4 types of black tea tea bag extract" can reduce viral infectivity, only "black tea powder solution" and "black tea tea bag extract" can work in 10 seconds, effectively reducing the number of viruses by 1/100,000; "green tea powder solution" takes 10 minutes.
In addition, drinking black tea can also help improve immunity. The study conducted a clinical trial on 72 people aged 20 to 60, allowing them to drink 3 cups of black tea a day for 12 weeks , it was found that the subjects became less likely to catch a cold, and even if they had a cold, it was difficult to become severe.
The study also pointed out that polyphenols can stay in the mouth for about 10 minutes. In addition to drinking more black tea to reduce the number of viruses, it can also prevent droplets from spreading to relatives and friends. Therefore, it is recommended to drink black tea slowly. The frequency of drinking black tea can effectively prevent epidemics.

Wuhan scientists: New covi variant NeoCoV has high mortality rate
As the world continues to battle against the covid pandemic, a
group of Chinese scientists from Wuhan and Beijing have issued a warning against a variant of coronavirus named NeoCoV, which is said to be more lethal with a
higher infection rate.
As per a report by the Russian news agency Sputnik - published
by several media outlets, the NeoCov variant was discovered in South Africa and
it is claimed to be related to the respiratory syndrome MERS-COV.

NeoCoV linked to MERS outbreaks
However, NeoCov is not entirely new because it is linked to the
MERS-CoV virus and its outbreaks were previously discovered in the Middle
Eastern countries in 2012 and 2015.

Wuhan researchers: One in three patients dies from NeoCoV
Chinese researchers weighed in on the mortality rate stating
that 'one in every three infected person dies', highlighting the higher death
rate.
Analysing the study, the tendency
of NeoCoV appears to be similar to the SARS-CoV-2, which causes COVID-19 in
humans. Scientists have said that NeoCoV was discovered in a bat
population.

NeoCoV and PDF-2180-CoV can
infect humans
However,
an unpeered study published on the bioRxiv website,
mentioned that NeoCoV and its close relative PDF-2180-CoV can infect humans.
News (8)
Receptor for NeoCoV mysterious
A
part of the published report read: "Middle East Respiratory Syndrome
coronavirus (MERS-CoV) and several bat coronaviruses employ Dipeptidyl
peptidase-4 (DPP4) as their functional receptors. However, the receptor for
NeoCoV, the closest MERS-CoV relative yet discovered in bats, remains
enigmatic."

Russia research: NeoCoV is not
actively spreading among humans
After a briefing on NeoCoV, experts from the Russian State Virology
and Biotechnology Research Center issued a statement on Thursday (January 27),
which states: "The Vector research centre is aware of the data obtained by
Chinese researchers on the NeoCoV coronavirus. At the moment, the issue is not
the emergence of a new coronavirus capable of actively spreading among
humans."
"In this study, we unexpectedly found that NeoCoV and its
close relative, PDF-2180-CoV, can efficiently use some types of bat
Angiotensin-converting enzyme 2 (ACE2) and, less favorably, human ACE2 for
entry," it added.

Experts warn potential risks of NeoCoV during the covid pandemic,
further study and investigation needed
The experts have warned against the potential risks, mentioning
that further study and investigation are needed to understand the immune
escape.
Of late, coronavirus cases have seen a spike globally after the
emergence of the 'variant of concern' Omicron.
More information and inputs are needed to establish a concrete
report on NeoCoV.

WHO will further study on NeoCoV
Although there is no official statement from World Health
Organization (WHO), the global health body was quoted by Russian news agency TASS
as saying that the claim requires further study.
The organisation told TASS, "Whether the virus detected in
the study will pose a risk for humans will require further study."
It also added that it "works closely" with the World
Organization for Animal Health (OIE), the Food and Agriculture Organization
(FAO) and the UN Environment Program (UNEP) to "monitor and respond to the
threat of emerging zoonotic viruses."

Origins of the name NeoCoV exposed
The word Neo, to the commoner, is a Chinese surname. In
Cantonese, it means “new” and translated to Greek it is “Neu”.
If the World Health Organization were to rename the
coronaviruses, NeoCoV should be renamed as “Rho” and Omicron as “Pi” according
to the Greek alphabetical order (since "Nu" and "Xi" were skipped). NeoCoV is not a new coronavirus.
To name a coronavirus “Neo” is offensive to the Chinese and to
parents who name their children “Neo”. Belgian Wout said he named his son “Neo”
and he finds the covi variant “NeoCoV” offensive to his culture.
According to The Hindu,
NeoCoV is a bat coronavirus that was first identified in 2011.
It was identified in a species of bats known as Neoromicia, which is where the
name NeoCoV was derived from. Commonly known as aloe bats, this species is
distributed in the Afro-Malagasy region. NeoCoV shares an 85% similarity to
MERS-CoV in the genome sequence, making it the closest known relative of
MERS-CoV.
Does NeoCoV infect humans and cause high
mortality?
It is important to note that inherently, NeoCoV cannot interact
with human receptors, implying that in its current form the virus cannot infect
humans. NeoCoV does not infect humans yet and has thus not caused any deaths.
What does the preprint say, and why is it
important?
The study reports that despite their similarity, MERS-CoV and
NeoCoV use different receptors to infect cells. The bat coronavirus NeoCoV was
found to use bat ACE2 receptors for efficiently entering cells and the
interaction between NeoCoV and bat ACE2 receptors is different from what is
seen in other coronaviruses that utilise ACE2. The preprint also reports that
although NeoCoV does not have the potential to use human ACE2 receptors and
infect humans, specific mutations artificially created in the receptor-binding
domain of NeoCoV can enhance its efficiency to interact with human ACE2
receptors. These mutations have not yet been seen in NeoCov isolates from
natural settings.
SARS-CoV-2 is not the first coronavirus to infect humans and cause
large disease outbreaks, nor is it likely to be the last. The study highlights
that through further adaptation, coronaviruses like NeoCoV or other related
viruses could potentially gain the ability to infect humans. The interactions
between humans and animals continue to increase, given the expanding human
population and encroachment of animal habitats. While the likelihood of
spillover events are rare, an increased interaction can potentially accelerate
such events. To prevent future outbreaks, it will thus be important to monitor
this family of viruses for potential zoonosis while continuing research efforts
on understanding the complex receptor usage of different coronaviruses. Genomic
surveillance of human and animal viruses is therefore the key to understanding
the spectrum of viruses, and possibly provide early warning to potential
spillover events.

Wuhan scientists' study has not been peer-viewed
In their studies collated under the title "Close relatives of MERS-CoV in bats use ACE2 as their functional receptors", the Wuhan scientists from the State Key Laboratory of Virology, Institute for Vaccine Research and Modern Virology Research Center of the College of Life Sciences, Wuhan University, explore how coronaviruses similar to MERS-CoV interact with different receptors in different host cells. Their work has not been peer-viewed. Their study, which was uploaded on biorxiv, describes the NeoCoV coronavirus.

U.S. Government study admits covid vaccine lengthens menstrual cycles
Reporter : Natalie Winters, The National Pulse
A U.S. National Institutes of Health study found
that COVID-19 vaccines lengthened women’s menstrual cycles.
The study, published in a January edition of Obstetrics
& Gynecology, compared menstrual cycle lengths between
women vaccinated and unvaccinated against COVID-19.
“For vaccinated individuals, data was from three consecutive
cycles before vaccination and from three more consecutive cycles, including the
cycle or cycles in which vaccination took place. For unvaccinated individuals,
data was collected for six consecutive cycles,” reads a summary of the study.
Of the 3,959 individuals analyzed, 2,403 were vaccinated, with
most receiving either a Pfizer or Moderna jab, and 1,556 were
unvaccinated.
On average, the first vaccination dose was associated with a
.71-day cycle increase in cycle length and the second dose with a .91-day
increase.
Dr. Diana W. Bianchi, Director of the National Institutes of Health (NIH)
Eunice Kennedy Shriver National Institute of Child Health and Human
Development, emphasized how “little research has previously been conducted on
how vaccines for COVID-19 or vaccines for other diseases could potentially
influence the menstrual cycle.”
NICHD and NIH’s Office of Research on Women’s
Health funded the study as part of $1.67 million grant to explore potential links between
COVID-19 vaccination and menstrual changes.
The vaccine side effect follows lobbying efforts from
pharmaceutical giants – especially Pfizer and Moderna – reaching
record highs in terms of spending and personnel hired. The massive lobbying
campaigns are likely responsible for nationwide vaccine mandates, which have subsequently been struck down by district
courts.
Similarly, the chairman and former Chief Executive
Officer (CEO) of the Thomson Reuters Foundation – James C. Smith – is a top investor and board member for pharmaceuticals giant
Pfizer.
