Conversion of Biological value

Wednesday, December 10th, 2008

Providing it is known which protein measurements were made relative to it is simple to convert from relative BV to percentage BV:
BV(percentage) = ( BV(relative) / BV(reference) ) * 100
BV(relative) = ( BV(percentage) / 100 ) * BV(reference)

Where:
BV(relative) = relative BV of the test protein
BV(reference) = percentage BV of reference protein (typically egg: 93.7%).
BV(percentage) = percentage BV of the test protein

While this conversion is simple it is not strictly valid due to the differences between the experimental methods. It is, however, suitable for use as a guideline.

What is Vegetarian Diet Pyramid

Thursday, December 4th, 2008

Vegetarian Diet Pyramid is a nutrition guide that represents a traditional healthy vegetarian diet. Variations of this traditional healthy vegetarian diet exist throughout the world, particularly in parts of North America, Europe, South America, and most notably, Asia. Given these carefully defined parameters, the phrase “Traditional Vegetarian Diet” is used here to represent the healthy traditional ovo-lacto vegetarian diets of these regions and peoples. The pyramid was created by Oldways in 1998 with scientific research from Cornell and Harvard University and specific reference to the healthy patterns of eating demonstrated by the Mediterranean Diet Pyramid.

The Vegetarian Diet Pyramid suggests the types and frequencies of foods that should be enjoyed for health. The pyramid is divided into daily, weekly, and monthly frequencies, but does not recommend serving sizes. The pyramid also has recommendations for daily physical activity and hydration.

According to the 1995 Dietary Guidelines for Americans, healthful diets contain the amounts of essential nutrients and energy needed to prevent nutritional deficiencies and excesses. Healthful diets also provide the right balance of carbohydrates, fat, and protein to reduce risks for chronic diseases, and they are obtained from a variety of foods that are available, affordable, and enjoyable.

The healthfulness of this pattern has been corroborated by epidemiological and experimental nutrition. See below for sources and references.

Abuse OF Dopamine reuptake inhibitor

Thursday, December 4th, 2008

In general, the abuse potential of DAR inhibitors depends on how they affect the pattern of dopamine release and reuptake.

Compounds that inhibit reuptake and also induce release of dopamine, such as methamphetamine or phenmetrazine, or compounds that inhibit reuptake but have no effect on release, such as cocaine or methylphenidate, tend to be addictive drugs with potential for abuse in humans.[1]

On the other hand, compounds that inhibit reuptake but also inhibit release of dopamine, such as bupropion and vanoxerine, have mild stimulant effects and little abuse potential, and can be used to treat stimulant addiction. [

Mechanism of Dopamine reuptake inhibitor

Thursday, December 4th, 2008

DARIs bind at the transporter molecule and form a non-covalent complex with it.[citation needed] When the DARI-molecule is large enough, which is normally the case, it suppresses the binding of other substances that are transporter substrates, such as endogenous compounds (like dopamine) and drugs (e.g. amphetamine).[citation needed]

What is Dopamine reuptake inhibitor

Thursday, December 4th, 2008

Dopamine Reuptake Inhibitors (DARI), Dopamine Uptake Inhibitors, Dopamine Transporter Inhibitors are compounds that inhibit the reuptake of extracellular dopamine back into the presynaptic cell by blocking the cell membrane-spanning dopamine transporter. Dopamine is a powerful neurotransmitter that is responsible for reward and drive. It is involved in various feelings such as euphoria, orgasm, anger, addiction, love, pleasure. Dopamine reuptake inhibitors allow dopamine to remain in the synaptic cleft and activate the receptors for a longer period of time, and some drugs can create a drug induced euphoria. Cocaine, a DARI, is notorious for this effect. A few prescription drugs such as methylphenidate and to a lesser extent bupropion (Wellbutrin) have this mechanism of action as well. Side effects from these drugs can be mixed. In some they induce euphoria, and in others they may induce restlessness and irritabilit

Alexander Parkes of Celluloid

Thursday, December 4th, 2008

The first celluloid as a bulk material for forming objects was made in 1856 in Birmingham, England, by Alexander Parkes, who was never able to see his invention reach full fruition. Parkes patented his discovery after realising that a solid residue remained after evaporation of the solvent from photographic collodion, he described it as a “hard, horny elastic and waterproof substance”.

Parkes patented it as a clothing waterproof for woven fabrics in the same year. Later in 1862, Parkes showcased Parkesine at the Great Exhibition in London where he was awarded a bronze medal for his efforts. Cellulose nitrate was dissolved in a small measure of solvent, this was then heated and rolled on a purpose built machine which extracted a proportion of the solvent. Finally, the use of pressure or dyes completed the manufacturing process. In 1866, Parkes tried again with his invention and he created a company to manufacture and market Parkesine but this failed in 1868 after trying to cut costs to enable further manufacture.

Content of page Udos Choice Food Pyramids

Thursday, December 4th, 2008

Udo’s Choice Food Pyramids are three nutritional advice pyramids developed by Udo Erasmus: one each for “healthy” people, “sick” people and “active” people. Pointing to growing levels of obesity and degenerative illnesses as evidence that conventional nutritional advice is not working, he developed these food pyramids which place more emphasis on green vegetables and good-quality plant oils such as in nuts and seeds, and less emphasis on carbohydrates and processed foods.

Draft alternative treatment paragraph of Coppertwig Sandbox2

Thursday, December 4th, 2008

Daily multivitamin supplements have been found to reduce HIV disease progression among men and women. This could become an important low-cost intervention provided during early HIV disease to prolong the time before antiretroviral therapy is required.[6] Various forms of alternative medicine have also been used to treat symptoms or alter the course of the disease.[3] Examples of alternative medicine that people have used in an effort to improve their symptoms, disease progression or quality of life include massage, stress management, acupuncture;[3], boxwood[7], and bowel-tolerance-dose vitamin C [8] [9]. [10] When used with conventional treatment, many now refer to these as “complementary” approaches. There is a concerning shortage of studies to establish the effectiveness of complementary and alternative treatments for HIV/AIDS. [5]

Reasons in support of this suggestion:
This suggestion addresses two ongoing disputes and hopefully may be a compromise solution to both of them.
This paragraph is factual and supported by citations.
It provides links and footnotes allowing the reader interested in alternative therapies to easily find more reading material on the subject.
It is shorter than the original. Some editors had expressed the opinion that the alternative therapy section was “too long”.
It increases the prominence of the result about vitamin supplementation by moving this information to the beginning of a paragraph. At least one editor seems to have missed seeing this interesting information on earlier reading of the article.
It removes vague, misleading and uncited (as far as I see) material about the changing definition of alternative therapy. The current paragraph give the misleading impression that alternative therapies are no longer used much. The phrase “community-based” doesn’t seem to mean much: surely every AIDS patient is in some sort of community?
The proposed paragraph mentions four or five alternative therapies for which there is some evidence of effectiveness. The Mills paper lists studies showing statistically significant support for stress management, massage and boxwood, while the Cathcart and Hickey references provide evidence in favour of bowel-tolerance-dose vitamin C. (Does the Saltmarsh reference provide evidence in support of acupuncture for AIDS?) The current version of the article mentions “flower remedies” for which I haven’t seen evidence of effectiveness.
The current paragraph has no mention of vitamin C nor any link to further information on it. Mentioning vitamin C is important for the following reasons:
People with AIDS are typically able to consume 40 to 100 grams of vitamin C, according to Cathcart (1984), without the diarrhoea-like symptoms that a normal healthy person experiences on ingesting about 2 to 6 grams of the vitamin. This suggests that the body of a person with AIDS is able to consume and utilise these amounts of vitamin C.
For a number of other illnesses during which people are able to ingest larger than normal amounts of vitamin C without the usual side effects, there is some evidence that ingesting these amounts leads to reduction of symptoms of the sickness and improvement in health.
There is evidence from anecdotal reports from two different authors that large doses of vitamin C lead to clinical improvement in AIDS patients.
Vitamin C is known to be used in a number of ways by the immune system — for example, chemotaxis, production of interferon and production of hydrogen peroxide for killing pathogens.
When animals who produce their own vitamin C (most mammals, for example) get sick, they produce increased amounts of vitamin C comparable to the bowel-tolerance-dose in humans.
Vitamin C is of low cost and low toxicity, therefore a simple cost-benefit analysis suggests that if there is a reasonable likelihood that it may be beneficial, it is worth using.
The last sentence of the Treatment section is currently in dispute. The last sentence of this proposed edit is a version of that sentence which more closely reflects the actual citation: for example, the quote given above from the citation in support of the current sentence does not use the word “proven” but does use the words “concerning” and “established”. The vocabulary and overall message of this new proposed sentence are closer to the original meaning of the citation.

If anyone objects to anything about this proposed edit, please discuss it here, and please propose alternative edits which address the above concerns, which satsify the list of criteria (which I proposed earlier and which no one has objected to), and which you believe are likely to be accepted by all involved.
