An “Unlimited Supply” of Disease-Free Blood?!?

If this is your first visit, please consider subscribing to my RSS feed. That way you'll be sure not to miss a thing!

Researchers at the biotechnology company Advanced Cell Technology say they have successfully used embryonic stem cells to grow human blood cells. 10 to 100-billion blood cells have been generated at a time and this technique could put an end to problems in sourcing blood for transfusions.

The hope is to be doing human trials of the lab grown blood by the end of 2009. The military will probably be the first to use this new technology.

It has now been shown that very large quantities of red blood cells can be generated from human embryonic stem cells. These cells are just like normal, transfusible blood. Whole tubes of blood have been generated in the lab from scratch. They have then gone on to successfully show for the first time that this blood is actually able to upload and load oxygen just like normal red blood cells.

This process can be used to create all the different blood types.

The next step in the testing process is to make sure the lab-grown blood cells maintain their integrity the same way normal blood cells do. Eventually, human testing will be necessary. The very first steps would be to use very small amounts of these cells that were labeled. The goal is to make sure they behave appropriately in humans.

Although embryonic stem cells were used in this study, researchers are confident that other types of stem cells could also be used.

Retailers Aren’t Required to Pull Many Expired Items From Their Shelves

Two drug store chains (Rite Aid and CVS) are being targeted and sued for selling expired dairy products, medicine and baby formula. The most surprising part about this situation is that neither federal nor state law requires most food items to be pulled from shelves when expired.

There are no policies as far as requirements for expiration dates on products except for pharmaceuticals and baby food. According to the FDA, the federal government requires expiration dates be printed on infant formula and baby food and these items must be removed for sale after that date. If this is not done, retailers can be held legally and financially responsible.

For other consumables, however, as long as a date is not tampered with for the purpose of misleading the consumer about a product’s freshness, there are no concrete rules about pulling items from the shelves past their prime.

Don’t think that retailers don’t have systems in place for product rotation, though. Employees routinely check for and remove outdated or nearly outdated items from shelves and use expiration dates as a guide. Items nearing expiration are usually clearly marked with reduced prices.

A wary shopper will check expiration dates to make sure that items bought are within freshness dates.
Consumer advocates recommend checking freshness dates before making purchases.

Most companies have return policies that allow for the exchange of outdated goods. Though expiration dates themselves are not mandated, product quality is.

Stores are not required to date items, but they are required to sell wholesome, safe food. Sell-by dates are a tool that helps sores manage this.

How to read freshness labels:

Best if used by or best before – The item is best used before the printed date for the best quality and flavor but is considered safe if consumed after.

Closed or coded dates – Printed for use by the manufacturer, these dates are found on canned and dry goods and are often indecipherable to consumers. Some use a month-day-year code (MMDDYYYY) or every day of the year is consecutively numbered. For example, January 1 would be printed 001 and December 31 would appear as 365. This is only one type of dating – the easiest to guess. These dates can contain fewer numbers or partial dates like only 2 digits for the year instead of 4, and the year can appear before or behind the month and day. You have to know which system is used or a “guess” could be wrong by years.

Sell by – This tells the store how long to display an item. Consumers should consume, cook or freeze the item within one to two days.

Use by – This is the last day the manufacturer predicts the item will be edible at “peak quality.”

A spoiled carton of milk offered for sale within its stamped expiration date would be wrong; a wholesome pound of ground beef offered for sale after its sell-by date is not unlawful.

Display dates speak to an item’s quality rather than its safety. Usually, food kept after its listed date will be safe to eat. The date listed is the manufacturer’s best estimation of the product’s peak taste and quality. Food should be consumed or cooked before its listed “use-by” date or at least within one or two days of its “sell-by” date.

Food that is immediately and properly frozen is considered safe indefinitely. Keep in mind, though, that food containing harmful bacteria such as salmonella or E. coli will be unsafe even before it expires.

How About a Bio-Weapons Lab in Your Town?

The U.S. Department of Homeland Security (DHS) has just released a large report containing its plans to build a mega bio-defense lab for scientists to study the Earth’s deadliest diseases. It seems it will be a real-life version of The Andromeda Strain.

Amazing? Exciting?

There is one small problem…leaks from the lab are expected to happen according to the report.

The department has also assessed the possibility of a terrorist attack resulting in the release of pathogens from the lab. This would involve the most infectious animal disease (Foot and Mouth) and those most deadly to humans (Hendra and Nipah viruses).

The overall risk assessment for a release at the five mainland sites was “moderate” because of “the potential easy spread of a disease through livestock or wildlife” nearby, according to a statement.

Plans are for the new lab to be built in 2010 and it will replace an existing bio-defense lab on Long Island. That lab is called the Plum Island Animal Disease Center and is considered outdated and no longer useful.

DHS wants its researchers to study “zoonotic diseases.” These are diseases that travel from animals to people (”bird flu”?). To do that they need a facility rated “bio-security level 4,” (the highest level). Plum Island is a level 3. Approximately ten percent of the new facility will be at level 4.

DHS is currently considering five possible sites in the mainland United States.

What is Mobile Cancer?

The studies and survey conducted by Australian Health Research Institute indicates that due to billions of times more volume of electromagnetic radiation emitted by billions of mobile phones, internet, intranet and wireless communication data transmission will make almost one-third of world population (about two billion) people sick with ear, eye and brain cancer.

The tissues of children are especially sensitive and are likely to be more effected by use of any wireless devices and they should not be encouraged to use mobile phones. These dangerous effects have been confirmed repeatedly by many leading medical and scientific research institutions around the world.

Insurance Fraud is Business as Usual in the US

The health insurance system in the United States works great, as long as you stay healthy. It’s only people who need medical care who have problems.

Here is the basic scenario:

You go to the doctor and pay directly. You send your bill to the insurance company for reimbursement. You then get a form letter from your insurance company rejecting the claim. It happens frequently.

If you’re persistent, you call your insurance company and demand to know the reason the claim was rejected. The insurer gives you a form for your doctor to fill out. Your doctor fills out the form and returns it but still the insurer does not pay the bill.

If you’re very persistent, you call back your insurance company and demand to know the reason the claim has not been paid. The insurer tells you that they never received the form from the doctor. With irritation, the doctor fills out the form again. The bill is still not paid.

If you’re extremely persistent, you call the insurer again and demand to know the reason the claim was rejected. The insurance company this time tells you that the doctor filled out the wrong form.

In the end your persistence may pay off and you will get reimbursed for your claim. It helps if you are well-educated in your rights under the insurance contract, though.

What if this denial scenario involved someone who is not very well-educated, has a language barrier, or does not have the physical or mental ability to pursue the insurance company? That person might just have assumed the insurance company was right to turn down their claim and not contested the issue. Or, if they contested it once, they might have let it drop after the first round or the second.

An insurance company denies a claim initially almost as a matter of course. For the price of a stamp, they can save themselves a reimbursement that may cost them thousands of dollars. Worst case scenario, they encounter persistent people who demand that they honor their contract. When this happens they only end up paying what they would have paid in the first place and they are able to make money on the float until they do pay. They don’t face any fines or penalties for wrongly denying these claims.

What is the basis for denied claims? You can’t get that information. How often do insurers deny claims? You usually can’t have this information either.

This is not the only information that you can’t have. With most policies, when people go “out of network,” the insurance company will reimburse an amount that is 70 % to 80 % of the “reasonable and customary” rate. This rate will not typically be disclosed in advance by the insurer. This means that patients will not know how much a doctor visit will actually cost them until after the doctor submits the claim. Also, the insurer is free to change their reimbursement rate at its own discretion. In addition, the insurance company can, at its own discretion, change what procedures are and are not covered.

Most businesses don’t get to write their own rules. There is no reason to make an exception for insurers, especially since they typically are dealing with people with serious health problems. This being the most vulnerable segment of the population.

Exploring GMO Seeds and Biotechnology - Part 2

Filed under Health, Makes You Wonder

So…do we have options? Are we just at the mercy of the big seed companies and corporations who seek to control the food production of the world?

I admit I was feeling quite overwhelmed and powerless until I did a little further reading and then I became convinced that we do have a few options, at least personally in our own little worlds…if we so choose.

It is possible to acquire, preserve and store a diverse variety of food and herbal non-GMO seeds and thus enable the human race to have access to non-GMO food and herbs in the days to come.

Thanks to a very informative website that I was fortunate to find this week, I have found that there are some sources for garden seeds. Visit www.BePrepared.com (800-999-1863; AF1-FG-S200). There you will find items like Garden Seeds in a Can (16 jumbo foil-lined packets of open pollinator seeds) - not terminator seeds!

We need to realize that once the GMO terminator seeds from the big seed companies finish integrating with seeds in nature, seeds that you and I store will be the only natural seeds left for all of humanity. This is very scary, considering that the seed companies admit that this is already occurring.

Lastly, I would like to encourage all of my readers to visit The Nutrition and Disease website that a recent reader shared with me. I spent several hours reading yesterday evening and this site is full of exciting and important information. You really don’t want to miss it.
