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.

Texas Judge Blocks Governor's Order Halting Transport Of Covid-Positive Illegals

Courtesy of ZeroHedge View original post here.

In a short-term victory for the Biden administration, a federal judge in Texas blocked an executive order which restricts the transport of infected illegal immigrants on Tuesday, suggesting that the order itself would have the effect of "exacerbating the spread of COVID-19."

U.S. District Judge Kathleen Cardone of El Paso agreed with the Justice Department, which accused Governor Greg Abbott (R) of potentially worsening the spread of the virus - as impeding the transfer of undocumented migrants would prolong the ...

Crude Oil Cleared For Blast Off On This Dual Breakout?

Courtesy of Chris Kimble

Is Crude Oil about to blast off and hit much higher prices? It might be worth being aware of what could be taking place this month in this important commodity!

Crude Oil has created lower highs over the past 13-years, since peaking back in 2008, along line (1).

It created a “Double Top at (2), then it proceeded to decline more than 60% in four months.

The countertrend rally in Crude Oil has it attempting to break above its 13-year falling resistance as well as its double top at (3).

A successful breakout at (3) would suggest Crude Oil is about to mo...

According to the Suez Canal Authority, the 1,312 foot long (400 m) container ship ran aground during a sandstorm that caused low visibility, impacting the ship’s navigation. The vessel is owned by Taiwanese shipping firm, Evergreen Marine.

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
