  T4 - Wikipedia, the free encyclopedia
The T-4 Euthanasia Program was established by Nazi Germany in order to maintain the supposed purity (eugenics)of the so-called Aryan race by systematically killing children and adults born with physical deformities or suffering from mental illness.
In Canadian tax law, a T4 is a renumeration of income tax and other deductions taken by the government over the period of one fiscal year, and is used in filing an Income Tax Return.
In anatomy, T4 is the 4th thoracic vertebra or the T4 spinal nerve.

 HIV & AIDS - A Critical Analysis of the HIV-T4-Cell-AIDS Hypothesis
T4 cell counts "can vary widely between labs or because of a person's age, the time of day a measurement is taken, and even whether the person smokes" (Cohen, 1992).
T4 cells were less than 200X106/L before 46 of 49 episodes of PCP, 8 of 8 episodes of CMV pneumonia, 7 out of 7 Cryptococcal neoformans pneumonia, 19 of 21 episodes of Mycobacterium avium-intracellulare pneumonia, 6 of 8 [pulmonary] KS and in 30 out of 41 non-specific interstitial pneumonia.
In conclusion, decrease in the number of T4 lymphocytes irrespective of how it is induced, that is, by destruction of the T4 cells or by a phenotypic change, and of its cause, is neither necessary nor sufficient for the appearance of KS and OI including PCP, that is, of the clinical syndrome.

 T4: The Test
Since free T4 is the active form of thyroxine, it is thought by many to be a more accurate reflection of thyroid hormone function and, in most cases, its use has replaced that of the total T4.
A T4 and TSH test may be ordered to help evaluate a patient with an enlarged thyroid gland (a goiter) and to aid in the diagnosis of female infertility.
Low T4 results in conjunction with a low TSH level or high T4 results along with a high TSH may indicate a pituitary gland condition.

Most of the T4 in the blood is bound to proteins; this acts as a reservoir of available thyroxine because only free T4 is active on cells.
T4 appears to be converted to T3 within cells, before it enters the nucleus and interacts direction with DNA, eventually resulting in the production of various proteins by the cell.
Only 0.03% of the T4 in plasma is free (soluble and active) and 0.3% of the T3 is free; the rest is bound to protein.

 All About Thyroid Hormone
When T4 reacts with the cells that comprise the body’s organs, including the pituitary, liver, brain and skeletal muscle, it loses an iodine atom to become T3.
Since T4 lacks the potency of T3, it was assumed that T4 would provide a safer therapeutic remedy than glandular extract, which contains all the various iodotyrosines as well as the thyroid hormone calcitonin.
However, highly influenced by the manufacturers of synthetic T4 who conducted their own studies, endocrinologists became convinced that the synthetic formulation was superior and allowed for more stable blood levels.

 Structural Studies Of T4   (Site not responding. Last check: 2007-10-09)
Bacteriophage T4 is one of the largest of the bacterial viruses, about 300 nm long and therefore is an ideal structural model.
T4 bacteriophage consists of an icosahedral head, where the DNA is stored, a contacting tail, six long and six short fibers.
This project highlighted two main characteristics of the T4 bacteriophage, the high sensitivity of the tail fibers to the processing involved in growing bacteria and purifying phage, and the phenomena of head expansion, which means that the head goes through different stages of expansion during DNA packaging.

The T4 features a longer wheelbase, a full 1/2 inch wider than the previous generation T3 truck, putting the T4 at the maximum ROAR legal dimensions for higher cornering speeds and stability during jumping and through bumpy sections of the track.
The T4 chassis provides a super-low center of gravity by lowering the motor, battery, and shock mounting positions, enabling Associated’s RandD team to design a sleeker, more realistic low-profile body, greatly reducing the large, unaerodynamic “humps” over the rear shocks as seen on older-design trucks.
The new T4 truck borrows the distinctive forward-swept front end and rear-mounted shock configuration featured on the RC10B4 buggy, optimized with the new co-planar steering geometry.

Finally, TSH itself is stimulated by another hormone, thyroid-releasing hormone (TRH), which is made by the hypothalamus.

But apart from the quality of the photos, the other thing that's great about the T4 is the waist-level viewfinder - perfect for taking surreptitious shots or just shooting from a different angle than most are used to seeing.
The only thing about the T4 that I'm unsure about is how its focusing mechanism works.
On that note, I've found that processing and printing makes a huge difference - the best shots taken with the T4 were processed and printed at high-end photolabs in the Bay Area whereas my less than spectacular pictures (most of which I did not include here) were done at 1-hr.

Despite treatment with T4 with dosages up to 0.3 mg/d, she continued to be depressed, have symptoms of hypothyroidism, and have a persistently elevated thyroid-stimulating hormone concentration.
This is consistent with the observation that T3 is superior to T4 as adjuvant therapy in the treatment of unipolar depression.
There is quite a controversy in a small niche in endocrinology between the old guard who believe that T4 is the only replacement to consider using, and a small little group who think that making TSH normal using T4 may still leave some people effectively hypothyroid.

 T4 test
This test measures the amount of a hormone in the blood, called T4, that is produced by the thyroid gland.
TSH causes the thyroid gland to produce two more hormones, T4 (thyroxine) and T3 (triiodothyronine).
In people with normal thyroid function, having enough T3 and T4 inhibits both TSH and TRH, which prevents the body from making too much T3 and T4.
