Leasing Space to the Government

GSA, the nation's largest public real estate organization, provides workspace for more than 1.2 million federal workers through its Public Buildings Service. Approximately half of the employees are housed in buildings owned by the federal government and half are located in over 7,100 separate leased properties, including buildings, land, antenna sites, etc. across the country.

Malocclusion: Disease of Civilization, Part IX

A Summary

For those who didn't want to wade through the entire nerd safari, I offer a simple summary.

Our ancestors had straight teeth, and their wisdom teeth came in without any problem. The same continues to be true of a few non-industrial cultures today, but it's becoming rare. Wild animals also rarely suffer from orthodontic problems.

Today, the majority of people in the US and other affluent nations have some type of malocclusion, whether it's crooked teeth, overbite, open bite or a number of other possibilities.

There are three main factors that I believe contribute to malocclusion in modern societies:
  1. Maternal nutrition during the first trimester of pregnancy. Vitamin K2, found in organs, pastured dairy and eggs, is particularly important. We may also make small amounts from the K1 found in green vegetables.
  2. Sucking habits from birth to age four. Breast feeding protects against malocclusion. Bottle feeding, pacifiers and finger sucking probably increase the risk of malocclusion. Cup feeding and orthodontic pacifiers are probably acceptable alternatives.
  3. Food toughness. The jaws probably require stress from tough food to develop correctly. This can contribute to the widening of the dental arch until roughly age 17. Beef jerky, raw vegetables, raw fruit, tough cuts of meat and nuts are all good ways to exercise the jaws.
And now, an example from the dental literature to motivate you. In 1976, Dr. H. L. Eirew published an interesting paper in the British Dental Journal. He took two 12-year old identical twins, with identical class I malocclusions (crowded incisors), and gave them two different orthodontic treatments. Here's a picture of both girls before the treatment:


In one, he made more space in her jaws by extracting teeth. In the other, he put in an apparatus that broadened her dental arch, which roughly mimics the natural process of arch growth during childhood and adolescence. This had profound effects on the girls' subsequent occlusion and facial structure:

The girl on the left had teeth extracted, while the girl on the right had her arch broadened. Under ideal circumstances, this is what should happen naturally during development. Notice any differences?

Vitamin D is ‘nature''s antibiotic’


Vitamin D is ‘nature''s antibiotic’Washington, Nov 24 : Vitamin D is being appreciated as "nature''s antibiotic” as a string of recent discoveries about the multiple health benefits of this nutrient have come to the fore.

Right from the health of your immune system to prevention of heart disease and even vulnerability to influenza, vitamin D is now seen as one of the most critical nutrients for overall health.

But it is also one of those most likely to be deficient – especially during winter when production of the "sunshine vitamin" almost grinds to a halt for people.

Analogs of the vitamin are even being considered for use as new therapies against tuberculosis, AIDS, and other concerns.

And federal experts are considering an increase in the recommended daily intake of the vitamin as more evidence of its value emerges, especially for the elderly.

"About 70 percent of the population of the United States has insufficient levels of vitamin D. This is a critical issue as we learn more about the many roles it may play in fighting infection, balancing your immune response, helping to address autoimmune problems, and even preventing heart disease," said Adrian Gombart, a principal investigator with the Linus Pauling Institute at Oregon State University.

Among other findings about benefits of Vitamin D is the ones made by OSU scientists that it induces the "expression" of cathelicidin, an antimicrobial peptide gene.

This explains in part how it helps serve as the first line of defense in your immune response against minor wounds, cuts, and both bacterial and viral infections.

Experts believe advances in the use of cathelicidin may form the basis for new therapies.

"Vitamin D insufficiency and deficiency is a world-wide, public health problem in both developed and developing nations. Nearly one billion people world-wide are deficient," the new report concluded.

The new report found that low levels of circulating vitamin D are associated with increased risk and mortality from cancer.

Vitamin D plays an important role in activating the immune system, fostering the "innate" immune response and controlling over-reaction of adaptive immunity, and as such may help control autoimmune diseases such as multiple sclerosis, psoriasis and rheumatoid arthritis.

The regulation of cathelicidin by vitamin D, a unique biological pathway for the function of vitamin D that could help explain its multiple roles in proper immune function, is so important that it''s only known to exist in two groups of animals - humans and non-human primates - and has been conserved in them through millions of years of evolution.

Epidemiological studies show a link between vitamin D deficiency and increased rates of respiratory infection and influenza, and it has been hypothesized that flu epidemics may be the result of vitamin D deficiency.

Higher levels of a protein linked to vitamin D have been associated with reduced infections and longer survival of dialysis patients.

Vitamin D has important roles in reducing inflammation, blood pressure and helping to protect against heart disease.

The study has been published in Future Microbiology, a professional journal. (ANI)

Security

The Department of Homeland Security's (DHS) Federal Protective Service (FPS) provides law enforcement and security services to over one million tenants and daily visitors to federally owned and leased facilities nationwide. The FPS has established itself as the center of expertise for physical security operations. From the installation of alarm systems, x-rays, magnetometers and entry control
