Glycemic Index, Sugar, Glucose

a: A complex carbohydrate ~
b: a string of pearls

What: Complex carbohydrates are polymers of sugars, often glucose. They digest much more slowly than pure glucose because of their large size and composition. Visually, a complex carbohydrate is like a string of pearls and a glucose is like a single pearl earring. To get a sense of how this size difference affects blood glucose levels; Image dropping a 30 pearl necklace on the floor; the necklace stays in one piece. Now imagine dropping 30 pearl earrings on the floor. The 30 earrings will explode over a wide area. This is what is occurring in your blood when you are constantly eating high-glycemic index foods; it is a constant explosion of glucose into your blood that stresses your pancreas to produce insulin to lower your glucose levels.

What: Once upon a time, I worked on an novel assay format that involved an antibody binding that changed the electrical current through a well. It looked great at time 0. However, the chemistry was so unstable that the linearity of the assay dropped after it sat around for about 30 minutes. An electronic device measured the change in several electoral parameters every 5 seconds for 16 wells. At the end of a 5 minute assay, about 3000 data points were generated for a single linear curve. People trying to make sense of the numbers saw what they wanted in the data. Some saw a line, some didn't. Once, I think I saw a picture of the Virgin Mary Riding a donkey to Bethlehem.

What: "An antioxidant is like the screen in front of your fireplace. It quenches the sparks as they form. If the fire in the fireplace is out of control, the screen is useless. Another analogy: antioxidant/free radical metabolism is that of the automobile engine and its cooling system. The engine runs on the burning (or oxidation) of fuel, creating energy and heat, giving your car power to move. If the process is uncontrolled the engine destroys itself because of the heat it has generated. The cooling system keeps the temperature within a normal operating range. The oxidative reaction is the burning of the fuel; the antioxidant is the cooling system. Balance between these two functions is the critical factor, both for your car and for you."

The pressure is equal and opposite to energy it has displaced. Matter is constantly seeking it's own level just like water. That is the level where all gravitational potential is equal throughout all of space. Matter displaces energy just like water. Two bodies gravitate because energy field equilibrium is upset by neighbor body. As bodies get closer, the force increases because energy field displaced is inversely proportional to distance squared. and they accelerate according to Newton's law. I call it the "energy displacement theory". Matter displaces energy. Matter has no physical meaning. It is merely "energy not" to use a boolean term."

What: "In the language of life, each of the ~23,000 genes/proteins encoded by the human genome is like a noun with its own special meaning. The possible interactions and functions of these proteins are akin to verbs. If we want to make real progress in understanding how cells work, a lot more researchers will need to markedly expand their biomolecular vocabularies. Otherwise, we will have a lot of data, but little knowledge."

Glycogen As A Role Of Quarters

a: Glycogen ~
b: a role of quarters

What: Glycogen, polymeric glucose, is like a roll of quarters and glucose is like an individual quarter. The body binds glucose molecules together to form glycogen. The analogy to coins is kinda like stacking quarters together to they can be put in a role of quarters for storage. There is an off/ on dynamics with glycogen/glucose. If there is excess glucose, some of it is bound to other glucose molecules to form glycogen. If glucose is need, as during exercise, glycogen is broken down to make glucose. This is sorta like taking from individual quarters from a role as you need to do laundry or make change.

The classic example is that taught in basic biochemistry, Sickle Cell Anemia. A single mutation in a gene leads to a change in an amino acid in Hemoglobin, which deforms the shape of these cells within human blood.

What: "Regarding the case in Australia, if the compositions of matter being patented consisted only in Open Reading Frames (ORFs), then it would not be appropriate to characterize them as "genes." Genes contain regulatory sequences, such as promoters, methyl groups, enhancers, and introns. If the ORFs were substantially lacking in these things, or if the ORFs were completely lacking in these things, then it would be the case that the compositions of matter were far removed and distant from what occurs in nature. I am not sure why journalists insist on using the term "genes" to refer to Open Reading Frames. An Open Reading Frame is like a boat that is missing a hull. Because an Open Reading Frame, almost by definition lacks regulatory sequences, the Open Reading Frame would not be able to function properly in its natural environment"

A good way to test an assay is to determine the values at the extremes. Likewise with an artillery shot. In theory, the math should get you on the target with one shot. But due to variations in wind speed, humidity and other factors, a little empirical range finding is often required. Hopefully, in both cases, you can hit the target.

These drugs are made of the same molecules that make up beef; that is proteins which are polymers made up of amino acids. As such raw beef and unformulated drugs can behave in a similar way. That is, if you leave a fresh piece of beef on a warm counter for an extended period of time it will rot. If you dry it out, the shelf life is expanded by many months. Likewise with biotech drugs. One means of stabilizing these products is lyophilization or better know as freeze drying. This removes the water which inhibits oxidation as well as bacterial contamination. There is much more to this process, but drying can stabilize beef as well as drugs.

Compared to the Google-bot, the Yahoo bot is like an alcoholic father who shows up every other week and falls asleep on the couch.

Collision Of Electromagnetic Energy And Matter

a: The interaction of a charged object and an electric field ~
b: the sea lifting and dropping a ship

What: "Your analogies for visualizing the interaction are nice: The classical interaction of a charged object in a changing electric field (like the water molecule dipole in the microwave) is like the sea lifting and dropping a ship. The interactions of quantum photons with other quantum particles are better thought of as 'impacts.'"........see the link for the rest..

Atom

a: The nucleus of an atom ~
b: a fly hovering in the middle of a football stadium

What: "The last thing that can be doubted is matter: hard solid world we live in. But is it? Is matter really what we think it is?! The answer is No. We live in - what Richard Dawkins calls - "the middle world". Matter is for the most part emptiness. There is way more emptiness in a seemingly solid matter than there is stuff. If we were small enough, we would see that the nucleus of an atom is like a fly hovering in the middle of a football stadium, the outer walls of the stadium being the electrons encircling the nucleus."

a: The plasmid ~
b: flash drive

What: "They have most of their genes on a chromosome that is passed just to the descendents of each bacterium. But some genes are on a tiny loop of DNA called a plasmid that can leave one bacterium and enter another. If a chromosome is like a hard drive of genetic information, a plasmid is like a flash drive-tiny and portable."

Tick Tel Tick Tel.......

a: The telomere ~
b: a cellular clock

What: "The telomere is like a cellular clock, because every time a cell divides, the telomere shortens. After a cell has grown and divided a few dozen times, the telomeres turn on an alarm system that prevents further division. If this clock doesn't function right, cells either end up with damaged chromosomes or they become "immortal" and continue dividing endlessly -- either way it's bad news and leads to cancer or disease."

They ignite the fuel in the mitochondria of the cell to produce energy with which the body performs all of its functions. For this reason, any problem with the thyroid gland causes energy problems and usually fatigue."

Data Conversion For Data Warehousing

a: Transferring and formatting data into a data warehouse ~
b: Origami

What: There sure is a lot of jargon in this field. Here' my summary of converting data from an operational database to a data warehouse. It goes something like this: Operational data are stored in OLTP software which consists of typical 2 dimensional relational tables. These work well for rapid and constant transactions: updates, insertions and deletions. To build a data warehouse, it's best to have data in a form in which it can be queried and displayed in a multitude of dimensions, which is the objective of having a data warehouse. Thus the conceptual model of the Rubiks cubes. But this is a conceptual model that helps humans visualize several dimensions, the data itself never "exists" in 3 dimensions. Data for a data warehouse are converted into and stored in a form which an OLAP tool can analyze it in a multitude of dimensions. This is the function of the star schema. It is a particular type of relational table structure in which 2 dimensional tables can be analyzed as if they were related to each other in a multitude of dimensions. A visualization crutch for this process might be the conversion that occurs with Origami, in which a 2-d object, a piece of paper, is converted into a 3-d object by systematic folding.
