T cells belong to a group of white blood cells known as lymphocytes and play a central role in cell-mediated immunity. They can be distinguished from other lymphocyte types, such as B cells and NK cells by the presence of a special receptor on their cell surface that is called the T cell receptor (TCR). The abbreviation "T", in T cell, stands for thymus since it is the principal organ for their development.

Urolithiasis




Urinary Calculus analysis

It has been published the typical descriptions of size, shape, color and texture for the diverse uroliths (see Figure 1). Nevertheless, the macroscopic morphology is too diverse as for to allow a diagnosis based on the physical aspect. Besides, many uroliths are composed by two or more substances arranged in several layers, principally in the dogs. It is necessary to carry out a correct analysis of each one of them to determine the types of mineral that they are constituted. The majority of the dogs and cats that form uroliths from metabolic origin, as soon as they did it, they will do it again until a preventive treatment begins.
Some other very useful methods exist to determine the mineral composition of the uroliths as: optical crystallography by oil dip with a polarized light, difractometry of X-rays, electronic microscopy, high pressure liquid chromatography, infrared spectroscopy, nevertheless, we have little experience with the use of these methods in the daily practice of our country.

The only available skill of commercial form in Mexico, to determine the mineral composition of an urolith is the mineral chemical semiquantitative analysis that allows us to determine the percentage of mineral compounds as phosphate, ammonium, magnesium, calcium, oxalate, urate, carbonate and cystine that can form the urolith. As a general rule, is important to send all the uroliths that are extracted from the urinary tract for their analysis.

X-Ray Painting,


 style in Australian aboriginal art in which the skeletons and internal organs of animals, fish, and birds are superimposed with the animals’ external features. X-ray paintings are often highly stylized, with complex, decorative designs. Found in the Northern Territory of Australia, the style appears in paintings on rock faces and bark. The origin of the style can be traced back to the Mesolithic art of northern Europe. Figures painted in the X-ray style can be up to 2.5 m (8 ft) long

Zoological Gardens

.........known popularly as zoos, in which live animals are kept for public recreation, education, and conservation purposes. Modern zoos offer veterinary facilities, provide opportunities for threatened species to breed in captivity, and usually build environments that simulate the native habitats of the animals in their care. Zoos differ from menageries, in which animals are displayed in cages for profit-making purposes, and from so-called zoological stations, which are established in the actual living areas of animals studied for scientific purposes.

Collections of captive animals have been kept since ancient times by rulers of countries as diverse as Egypt and China, but the concept of a zoological garden or park, in which animals may be given a practicable freedom of movement, is a recent development.

The first modern zoological gardens were the Imperial Menagerie established in Vienna in 1752 and opened to the public in 1765, and the zoo established in 1793 in connection with the Jardin des Plantes (Botanical Garden) in Paris. The famous zoological garden in Regent's Park, London, was established in 1828 by the Zoological Society of London. In 1931 the society opened Whipsnade Park, in Bedfordshire, an area of approximately 230 hectares (567 acres) that has become one of the world's best-known zoos. The oldest zoos in the United States are Chicago's Lincoln Park Zoo, opened to the public in 1868, and the Philadelphia Zoo, chartered in 1859 and opened in 1874. The International Wildlife Conservation Park, situated in Bronx Park, New York, and known popularly as the Bronx Zoo, opened in 1899. The Zoo was founded by the New York Zoological Society (now the Wildlife Conservation Society), and has one of the largest collections of animals in the world. Other large and particularly important collections are found in Missouri, California, Mumbai and Kolkata, Cairo, Tokyo, and Berlin and Munich.

From the 19th century onwards, the steel bars formerly used to restrain dangerous animals and protect the public were frequently replaced by ditches or moats, too wide and deep for the animals to cross. Hardy animals are permitted to roam over large, open-air ranges, while in cool seasons and climates, tropical animals are housed in heated buildings. In some zoological gardens animals of different species are exhibited in a common enclosure, sometimes including nearly all the animals of a region. Many modern zoos incorporate aquariums and aviaries for the purpose of accommodating and displaying exotic fish and birds, and frequently include a special children's zoo for very young visitors to play in and to ride on animals such as elephants and camels.

Deoxyribonucleic acid

(DNA) is a nucleic acid that contains the genetic instructions for the biological development of a cellular form of life or a virus. All known cellular life and some viruses have DNAs. DNA is a long polymer of nucleotides (a polynucleotide) that encodes the sequence of amino acid residues in proteins, using the genetic code.



Doppler shift-The "police siren" effect,when waves propagated by a moving body have their wavelength stretched as the body moves away.

Diurnal motion: The apparent daily rotation of the sky from east to west. It is due to the real rotation of the earth from west to east.

Dichotomy: The exact half-phase of Mercury, Venus or the Moon.

Diuretic

A diuretic (colloquially called a water pill) is any drug or herb that elevates the rate of bodily urine excretion (diuresis). Diuretics also decrease the extracellular fluid (ECF) volume, and are primarily used to produce a negative extracellular fluid balance. Caffeine, cranberry juice and alcohol are all weak diuretics.

Uses

In medicine, diuretics are used to treat heart failure, liver cirrhosis, hypertension and certain kidney diseases. Diuretics alleviate the symptoms of these diseases by causing sodium and water loss through the urine. As urine is produced by the kidney, sodium and water – which cause edema related to the disease – move into the blood to replace the volume lost as urine, thereby reducing the pathological edema. Some diuretics, such as acetazolamide, help to make the urine more alkaline and are helpful in increasing excretion of substances such as aspirin in cases of overdose or poisoning.

The antihypertensive actions of some diuretics (thiazides and loop diuretics in particular) are independent of their diuretic effect. That is, the reduction in blood pressure is not due to decreased blood volume resulting from increased urine production, but occurs through other mechanisms and at lower doses than that required to produce diuresis. Indapamide was specifically designed with this is mind, and has a larger therapeutic window for hypertension (without pronounced diuresis) than most other diuretics.

Delta-aminolaevulinic acid dehydratase


Lead poisoning


Lead has no known biological role in the body. The toxicity comes from its ability to mimic other biologically important metals, the most notable of which are calcium, iron and zinc. Lead is able to bind to and interact with the same proteins and molecules as these metals, but after displacement, those molecules function differently and fail to carry out the same reactions, such as in producing enzymes necessary for certain biological processes.

Most lead poisoning symptoms are thought to occur by interfering with an essential enzyme Delta-aminolevulinic acid dehydratase, or ALAD. ALAD is a zinc-binding protein which is important in the biosynthesis of heme, the cofactor found in hemoglobin.
Genetic mutations of ALAD cause the disease porphyria, a disease which was highlighted in the movie The Madness of King George.
Lead poisoning is sometimes mistaken for porphyria but the distinction is that lead poisoning usually causes anemia while true porphyria does not.

Dendrochronology


Dendrochronology or tree-ring dating is the method of scientific dating based on the analysis of tree-ring growth patterns. This technique was invented and developed during the 20th century originally by A. E. Douglass, the founder of the Laboratory of Tree-Ring Research at the University of Arizona. The technique can date wood to exact calendar years.


Overview

Many trees in temperate zones grow one growth ring each year, the newest ring being under the bark. For the entire period of a tree's life, a year-by-year record or ring pattern is formed that reflects the climatic conditions in which the tree grew. Adequate moisture and a long growing season result in a wide ring. A drought year may result in a very narrow one. Trees from the same region will tend to develop the same patterns of ring widths for a given period. These patterns can be compared and matched ring for ring with trees growing in the same geographical zone and under similar climatic conditions. Following these tree-ring patterns from living trees back through time, chronologies can be built up, both for entire regions, and for sub-regions of the world. Thus wood from ancient structures can be matched to known chronologies (a technique called cross-dating) and the age of the wood determined precisely. Cross-dating was originally done by visual inspection. Nowadays, computers are used to do the statistical matching.

To eliminate individual variations in tree ring growth, dendrochronologists take the smoothed average of the tree ring widths of multiple tree samples to build up a ring history. This process is termed replication. A tree ring history whose beginning and end dates are not known is called a floating chronology. It can be anchored by cross-matching either the beginning or the end section against the end sections of another chronology (tree ring history) whose dates are known. Fully anchored chronologies which extend back more than 10,000 years exist for river oak trees from South Germany (from the Main and Rhine rivers). A fully anchored chronology which extends back 8500 years exists for the bristlecone pine in the Southwest US (White Mountains of California).

In areas where the climate is reasonably predictable, trees develop annual rings of different properties depending on weather, rain, temperature, etc. in different years. These variations may be used to infer past climate variations —

Dialysis


In medicine, dialysis is a type of renal replacement therapy which is used to provide an artificial replacement for lost kidney function due to renal failure. It is a life support treatment and does not treat any kidney diseases. Dialysis may be used for very sick patients who have suddenly lost their kidney function (acute renal failure) or for quite stable patients who have permanently lost their kidney function (end stage renal failure). When healthy, the kidneys remove waste products (for example potassium, acid and urea) from the blood and also remove excess fluid in the form of urine. Dialysis treatments have to duplicate both of these functions as dialysis (waste removal) and ultrafiltration (fluid removal).

Diode

Semiconductor electronic component. Ideally, a diode conducts electricity in one direction and does not allow the current to flow in the opposite direction. Thanks to this property diodes are used to rectify alternating currents, i.e., to convert alternating current (AC) to direct current (DC).

History of the Depth Charge

The depth charge or bomb is a waterproof weapon used by ships or aircraft to attack submerged submarines.

First Depth Charges
The first depth charges were developed by the British in World War I for use against German submarines or U-boats, beginning in late 1915. They were steel canisters, the size of an oil drum, filled with TNT explosives. They were dropped off the side or stern of a ship, on top of where the crew estimated the enemy submarines were. The canister sank and exploded at a depth that was preset by the use of a hydrostatic valve. The charges often did not hit the submarines but the shock of the explosions still damaged the submarines by loosening the submarine enough to create leaks and forcing the submarine to surface.




The first depth charges were not effective weapons. Between 1915 and the end of 1917, depth charges destroyed only nine U-boats. They were improved in 1918 and that year were responsible for destroying twenty-two U-boats, when depth charges were propelled through the air over distances of 100 or more yards with special cannons, increasing the damage range of the naval ships.

KINETIC =To do with Movement as in "kenetic sculpture race"(from my home town)


   
Kinetic Sculpture Race
The Osgood File (CBS Radio Network): 11/27/03
The Osgood File (CBS Radio Network): 6/25/03

Human powered works of mobile art compete in a race each spring.

The sculptures that competed in the April 2003 Kinetic Sculpture Race are designed to travel on land, through mud and over deep harbor waters, and they are constructed of any imaginable material, including used bicycles, gears, feathers, tin foil and paper mache. Some of the machines are simple crafts piloted by only one brave soul, while others might be as large as 50-foot long, highly sophisticated and well-engineered vehicles powered by a team of pilots. This year 32 entries, including a 14-foot green frog, a 14-foot powder blue elephant and a mobile volcano will compete for prizes in "Art" and "Engineering" categories, as well as the coveted "Mediocre" and "Next to Last" awards.

Art meets engineering at the Kinetic Sculpture Race, which provides an opportunity for anyone to build and race an imaginative work of art. The race started inauspiciously when Hobart Brown, an art dealer and sculptor, was repairing his son's tricycle in 1969. "It was an accident. I didn't know the world was hungry for this kind of thing. I was repairing my son’s tricycle, and I kept building stuff on it and pretty soon it was seven feet tall. And it got in the newspaper and my friend built one (another kinetic sculpture) and we had a race and it (the competition) grew and grew. And I thought, oh my God, now we need to do it right." The race grew into an annual three-day event in Northern California, from Arcata to Ferndale during Memorial Day weekend each year, over a 38-mile route of road, water, sand and mud. Since then, Hobart, known as the "Glorious Founder," has taken his "festival of art and madness" to Baltimore, as well as Boulder, Colorado, Portland Oregon, Port Townsend, Washington and even Poland and Australia.

Psoralens





“Psoralens are part of a group of plant compounds referred to as furocoumarins. These are predominantly found the umbelliferae family, which includes celery, parsnips, fennel and parsley. Psoralens form part of the plants’ natural defence system and although they’re safe at low levels, their concentrations increase when the plants are damaged, attacked by fungi (mould), or when exposed to extreme temperatures."

The compounds are absorbed into the skin on contact, and they also end up in the skin after being ingested. Not that you would notice… until you went out into the sun, that is. Psoralens are partial to UV-A radiation, and have the amazing ability to absorb three times as much light energy compared to their ground state – and when they release this energy again, the trouble starts. Photochemical reactions take place which damage to the body’s cell membranes and DNA, causing inflammation and blisters, a condition medically referred to as “phytophotodermatitis”. In other words, victims end up with the equivalent of pretty bad sunburn. And because of the DNA damage, there is also an increased cancer risk (as there is with sunburn).

Don’t let this put you off your veg though – you’d have to eat large amounts of mouldy celery to run any serious risk of blistering up while out on the football pitch. The people most at risk from phytophotodermatitis are agricultural workers and food handlers who are exposed to these compounds on a near-daily basis.

Dangerous though they can be, psoralens can also be put to very positive use, by means of a therapeutic application called ‘PUVA’. Psoralen + UV-A therapy can help certain difficult-to-treat skin conditions, such as psoriasis, eczema and vitiligo. The psoralens are applied topically to the affected skin areas or, in more severe cases affecting large areas of the body, they are given orally. The patients are then exposed to UV-A light, and this can help to clear up the condition. The medical team take care not to burn the patients, of course. In vitiligo, the condition Michael Jackson has claimed to suffer from, where the skin’s natural pigment (melanin) is lost, PUVA therapy can help re-pigment the skin. The word of warning though is that during PUVA therapy, patients are advised not to consume psoralen-containing foods in excess.
