Swine Flu Update

Cliff Notes for “Swine flu: One Killer virus, three key questions.”

swine flu virusBy Ilene

Brendan Maher and Declan Butler, authors of a recently published Nature article “Swine flu: One killer virus, three key questions,” set out to answer three questions about the H1N1 virus. Here’s what they found. 

How does it kill?

Sherif Zaki, head of the infectious-disease pathology branch at the Centers for Disease Control, discusses his team’s observations from their pathological studies.    

1.  The H1N1 virus penetrates deep into the alveoli (the terminal air sacs in the lungs). In contrast, the seasonal flu viruses tend to infect cells higher in the upper airways. This deep penetration is reminiscent of the action of the H5N1 avian flu virus. Zaki commented: “[H1N1] is like avian flu on steroids.”  Why might this be?

Zaki says that his observations fit well with recent research looking at the mechanism of infection. A group led by Mikhail Matrosovich at Philipps University Marburg in Germany and Ten Feizi at Imperial College London studied sialyl glycans, glycoproteins that the flu virus binds to in order to gain entry to human cells. Although seasonal strains of H1N1 bind mostly to versions of the glycoproteins known as α2-6, the researchers found that the new pandemic H1N1 can also bind to a version called α2-3, which is found in greater proportion in the lower respiratory tract.

2.  In patients who have died, co-infection was common with H1N1.  Zaki’s group observed infection with bacteria such as Staph aureus or Streptococcus pneumoniae in about a third of the fatal swine-flu cases. However, in the remaining two thirds of fatal cases, the virus was lethal alone.  The damage seen in the lungs is characterized as ‘diffuse alveolar damage,’ reflecting a very difficult to treat state of respiratory distress syndrome. According to Zaki’s research, about 90% of the fatal cases had some underlying medical condition.

Zaki expects the number of flu cases to increase as the flu season “ramps up.”

How does H1N1 spread?

Brendan Maher visited Peter Palese’s laboratory at Mount Sinai School of Medicine where testing for how the viruses spread is being carried out. Researchers John Steel and Anice Lowen compared the transmissibility of H1N1 to that of seasonal flu using a guinea pig model. Their data indicate that the H1N1 virus transmits as efficiently as seasonal flu viruses, which is consistent with real-world data showing…

FedEx Corp.: Fundamentals Support the Price Increase

By F.A.S.T. Graphs. Originally published at ValueWalk.

Introduction

After reporting better than 4th quarter results on Tuesday, the stock price of FedEx Corporation (NYSE:FDX) has been on a tear. With this article, I plan to demonstrate that the fundamentals support the current price rise. Moreover, the fundamentals also suggest that it is not too late to take a long-term position in this leading air freight and logistics company.

Pedal to the Metal

Like a race car pushing the pedal to the metal, the stock market sped to its best quarterly stock market gains in decades. The +20% rebound in the 2nd quarter S&P 500 index was the best result achieved since 1998. Moreover, the Dow Jones Industrial Average saw its largest quarterly gain (+18%) since 1987, and the technology-heavy NASDAQ index (+31%) saw the most appreciation since 2001. While a snap-back after a shockingly dismal 1st quarter should come as no surprise to many investors, the pace of this rebound is unlikely to be sustainable at this ...

Gold / Dollar Ratio Sending Bullish Message To Gold Bugs!

Courtesy of Chris Kimble

It’s been a good year for gold bugs!

Gold has outperformed several asset classes as volatility and general economic uncertainty have come back to the forefront.

In today’s chart, we look at the ratio of Gold to the U.S. Dollar on a “monthly” basis. Gold bulls want to see this ratio trending higher… and it is.

In fact, the rise has taken the Gold ratio to an important juncture. It is working on a dual breakout at point (2).

Thus far, price is well above horizontal resistance marked by (1), and just above trend resistance at (2). Should the breakout hold, it would be historically bullish for Gold (and precious metals). Stay tuned!

Where is price going, is there strength or weakness in the chart?


Previous Post on the US Dollar : Where is the US Dollar trend headed ?


The question is always what will the future price action look like ?


This post will highlight the use of lines generated by angles. Not trend lines, as trend lines require two known points on a chart, where as angles require only one known point and a angle degree to draw a line. The question then becomes how is the angle degree determined.

These Charts Show COVID 19 Is Spreading in the US and Will Kill the Economy

The COVID 19 pandemic is, predictably, worsening again in much of the US. Only the Northeast, and to a lesser extent some Midwestern states, have been consistently improving. And that trend could also reverse as those states fully reopen.

The problem in the US seems to be widespread public resistance to recommended practices of social distancing and mask wearing. In countries where these practices have been practi...
