D225E and D225N H1N1 RBD Changes in Turkey

Recombinomics Commentary
January 5, 2010

The Refik Saydam National Public Health Agency has released 29 HA [hemagglutinin] sequences from Ankara, Turkey. Several were partial sequences, but 26 covered the receptor binding domain and 8 had D225E,… while one had D225N,… 

My comment:  D225 is the most common or wild-type receptor binding protein - the hemagglutinin (HA) protein – which enables the virus to bind to tissues in the respiratory tract of infected people. 

A change in the amino acid in position 225 of the receptor binding domain (RBD) is symbolized by using the letter representing the new amino acid, e.g. "G" for glycine in "D225G." The marker D225G signifies that a glycine (G) is present in the 225 position, replacing the amino acid usually in this position, aspartic acid, or D (hence the wild-type marker is "D225"). Glutamic acid, E, and asparagine, N, are two other amino acids that have been found in this position in non-wild-type swine flu viruses.

The change in the receptor binding protein from D to G alters the protein’s preference for binding to human tissues. Viruses with the D225G marker bind in the lung tissue, rather than binding in the upper respiratory tract (nasal area and throat), the more typical target. This appears to result in more severe disesase which may trigger a "cytokine storm" reaction in the lungs.  Whether substitution with "E" or "N" causes similar changes is not known. Theoretically, if the immune response is generated against the wild-type protein D225, viruses with D225G, D225E or D225N markers might avoid the immune system’s response. 

[Back to Dr. Niman] The outcomes of these patients were not given but media reports have described a rapid in increase in H1N1 fatalities in Turkey.  A large number of HA sequences with D225E has been published from Spain, and recently released GISAID sequences from Sweden and the UK also have D225E, including three fatal cases from Sweden. The prior reports of D225G and D225N associations with fatal cases has raised concerns that changes at position 225 could alter tissue tropism or aid in immune escape, leading to more severe and fatal cases.

Flu Watch Update – Ilene

When is a flu pandemic not a flu pandemic?

By Debora MacKenzie, consultant at New Scientist

H1N1 swine flu continues to roam the planet. In the US, cases are thought to be in the hundreds of thousands. In Japan, hundreds of teenagers have caught it, despite no obvious connections with Mexico or the US.

Yet in Europe, health authorities are not testing widely for it and are prescribing drugs as though they could still contain it. And in Geneva, health ministers have fought this week to keep the World Health Organization from following its own rules and calling this a pandemic.

So are we in a pandemic or not? And have we got the whole idea of a flu pandemic completely wrong?

No. There has been a phenomenal mismatch between quite sensible rules about how to declare a flu pandemic, and equally sensible rules about how to respond. The mismatch was wholly predictable, yet somehow no one saw this coming.

The WHO rules for declaring different degrees of flu pandemic threat are based on epidemiology (how the virus is spreading) for good reasons. This is because any new flu virus to which most of the world has little immunity, and which spreads well enough person-to-person to escape its continent of origin, is very likely to go global, and to cause more sickness and death than flu usually does. That is the definition of a flu pandemic

…As I write, the number of confirmed cases in Japan (and that’s just people sick enough to see a doctor and get tested) has jumped by 35 in the past 24 hours, to nearly 300, mostly due to that perennial vector of flu, the gregarious teenager. The main cluster started without any known links to the Americas.…

China Injects Gargantuan 1.1 Trillion In Liquidity This Week

Courtesy of ZeroHedge. View original post here.

Following what Bloomberg calculated was a record net reverse repo liquidity injection on Wednesday, when the PBOC injected a whopping 560 billion yuan of liquidity into the financial system via open market operations, the Chinese central bank has done it again and in Thursday's open market operation, it sold 250BN yuan in 7 Day repos (slightly below yesterday's record 350BN), and 150BN in 28 Day repos, which net of maturities resulted in a whopping net 380BN yuan ($56.2BN) liquidity injection.

The "Average Stock" is Facing a Big Test Here!

Courtesy of Chris Kimble.

The Value Line Geometric Index tends to give investors a good idea of the health of the overall market. It is an equal-weighted index with a broad swath of stocks that gives investors an idea of how the “average stock” is performing.

The Value Line Geometric formed highs in the same area in 1998, 2007, and 2015 (see blue line). In the last two years, the index broke out above that line and held above it until the recent correction.

It is now testing the underside of that price area (now resistance). Bulls will get good news with a breakout ABOVE thi...

Crypto-Bubble: Will Bitcoin Bottom In February Or Has It Already?

The new year has been relatively good for the price of bitcoin after a spectacular collapse of the cryptocurrency bubble in 2018. It’s up notably since the middle of December and traded around the psychological level of $4,000... so is this a sign that the crypto market is about to recover?

Of course, it depends on who you ask, but one analyst discovered a pattern which might point to a bottom next month.

D.E. Shaw Investment Calls For Leadership Change At EQT

By ActivistInsight. Originally published at ValueWalk.

Elliott Management has offered to acquire QEP Resources for approximately $2.1 billion, contending the oil and gas explorer’s turnaround efforts have done little to lift the company’s share price. The company responded and said that a thorough review of the proposition is imperative in order to properly act in the best interests of shareholders, “taking into account the company’s other alternatives and current market conditions.” The news came only a month after Travelport Worldwide agreed to sell itself to Siris Capital Group and Elliott’s private equity arm Evergreen Coast Capital for $4.4 billion in cash and two months after Athenahealth was bought by Veritas and Evergreen for $5.7 bi...

Weekly Market Recap Jan 13, 2019

Courtesy of Blain.

In last week’s recap we asked:  “Has the Fed solved all the market’s problems in 1 speech?”

Thus far the market says yes!  As Guns n Roses preached – all we need is a little “patience”.  Four up days followed by a nominal down day Friday had the market following it’s normal pattern the past nearly 30 years – jumping whenever the Federal Reserve hints (or essentially says outright) it is here for the markets.   And in case you missed it the prior Friday, Chairman Powell came back out Thursday to reiterate the news – so…so… so… patient!

Fed Chairman Jerome Powell reinforced that message Thursday during a discussion at the Economic Club of Washington where he said that the central bank will be “fle...
