Illegal Immigration and Politics

There simply is not an illegal immigration problem. Nor is the problem is solely one of political ideology. Rather, it is a legal problem. Take, for example, the position that the United States is a sovereign country with the obligation to protect its citizens from ‘external threats’ as described in the US constitution.. Include in the idea of ‘external threats’ a decrease in individual citizen’s physical security, invasion, and economic loss to citizens and US businesses.

Next ask the question, “Does illegal immigration constitute an ‘external threat’?”

This question devolves to each of it’s components:

Component	Situation	Threat
A decrease in individual citizen’s physical security	There has been an increase in murders, sex crimes, and physical assault against US citizens directly proportional to the number of illegal immigrants	Yes
Invasion	There are, by most accounts, over 10 million citizens of other countries in the US with out the permission of the US government and in violation of US laws. This is an invasion.	Yes
Economic loss to citizens	Wages in jobs filled my illegals are static or lower than prior to the invasion. This is an economic to US citizens in these and related jobs. US citizens cannot work for these wages while paying taxes, FICA, and meeting other requirements of employed legal residents.	Yes
Economic loss to US Businesses	Some US businesses competing in international trade acquire a competitive advantage through lower wages. In the long run, taxes must increase to support the unfunded social services required by illegals. Other businesses facing increased shrinkage, poor quality workmanship, increased security requirements, on-the-job language issues, labor disputes, and dissatisfied citizen employees face immediate financial burdens	No/Yes

A reasonable person would look at the above table and conclude that the United States is indeed experiencing an “external threat.”

Therefore, it is the responsibility of the Federal government under the Constitution to take all possible measures to eliminate this threat. To the extent that the Federal government fails to perform this duty as required by the constitution, federal officers, judges, and elected representatives are guilty of violation of their oath of office. All such officials, judges, and elected representatives should be impeached. This is not a political or ideological issue but rather a legal issue.

Leucine Metabolism and Alzheimer's Dementia

Background

Leucine is one of the twenty most common amino acids and coded for by DNA. It is isomeric with isoleucine. Nutritionally, in humans, leucine is an essential amino acid. (http://en.wikipedia.org/wiki/Leucine)
Leucine is the most common amino acid found in proteins, and is essential for optimal growth in infancy and childhood and for nitrogen equilibrium in adults. It is suspected that Leucine plays a part in maintaining muscles by equalizing synthesis and breakdown of proteins.
The major food sources of leucine are whole grains and milk and milk products. Eggs, pork, beef, chicken, pulses, Soya beans, and leafy vegetables are good sources of leucine.

An example of early-onset autosomal dominant familial Alzheimer disease (FAD) has been found to be caused by a leucine-to-valine change at codon 153 (L153V) of the presenilin 1 (PSEN1) gene. This finding raises the possibility that such substitution may also be induced by a chronic lack of Leucine in individuals with normal genes.

Observation 1

Elderly humans experience muscle wasting. This wasting can be stopped and even reversed through consumption of appropriately timed Leucine supplements. (http://news.bbc.co.uk/1/hi/health/4502862.stm)

Implication 1

Elderly humans absorb Leucine poorly from a normal diet. As a result, they become Leucine deficient.

Observation 2

In Alzheimer’s the beta-amyloid plaque contains Leucine.

Implication 2

An unknown process causes CNS accumulation of beta-amyloid plaque. Such accumulation can logically be caused through one of the following mechanisms:

1. Leucine is not excreted due to a failure of the normal excretory process:
1. Transport failure
2. Transport blockage
2. Leucine is abnormally retained

2. Age related failure of clean up process:

· Scientists make discovery in Alzheimer's (AP via Yahoo! News;Fri, 11 Aug 2006)
Scientists have discovered molecular janitors that clear away a sticky gunk blamed for Alzheimer's disease - until they get old and quit sweeping up.

3. Leucine is bound to the beta-amyloid plaque in a passive, non-active ingredient

Observation 3

Leucine is rapidly turned over in the normal brain.

Implication 3

An adequate supply of Leucine is necessary to support normal turn over in the brain.

Hypothesis

A systemic lack of Leucine caused by failure to absorb adequate amounts from the diet leads to abnormal brain Leucine metabolism that directly, or indirectly, causes a buildup of beta-amyloid plaque in the central nervous system.

Possible Approaches to Tests of the Hypothesis

1. Compare the systemic Leucine levels of Alzheimer’s and normal elderly adults.
2. Identify animals having a Leucine metabolism similar to humans and conduct an experiment whereby Leucine levels are manipulated and brain morphology is studied.
1. Dietary deprivation
2. Chemical interference in vivo.
3. Examine the effects on neural tissue of varying levels of Leucine in vitro.
4. Compare the levels of Leucine in animal models of Alzheimer’s.
5. Investigate the relationship between neurotoxins that cause Alzheimer’s like lesions and their effect on Leucine metabolism.
6. Investigate the morphology of muscle wasting related to Leucine deprivation.
1. Look for plaque related deposits in elderly muscles
2. Look for plaque related deposits in animals deprived of Leucine.
3. Look for neuromuscular junction effects in elderly muscles.
4. Look for neuromuscular junction effects in animals deprived of Leucine.
5. Consider the relationship between the known changes in neuromuscular junctions with aging and leucine supplementation.
7. Investigate the location of the beta-amyloid plaque buildup and localization of Leucine metabolism in Alzheimer’s and normal brains.
1. Developing a Leucine specific stain/antibody could accelerate such studies.
2. Explore the localization of Leucine metabolism in the normal CNS using both human and animal models. (A quick approach would be to use mice as an initial demonstration of differential Leucine metabolism across brain areas.)
3. Focus special attention on CNS astrocytes.
