"Mycotoxins" such as aflatoxin B1 (AFB1) are among the most potent liver-damaging toxins known.
Poultry are the most sensitive of all farm animals to the toxic effects of even small amounts of AFB1.
Additionally, the project was designed to find out if common and inexpensive FDA-approved food antioxidants, such as butylated hydroxytoluene (BHT) added to feed rations, could protect the birds.
The researchers determined that the extreme sensitivity of poultry to AFB1 appears to be due to an unfortunate combination of very efficient activation and deficient detoxification mechanisms in the poultry liver.

We also found that the resistance of tissues to spontaneous autoxidation and the amount of oxidative damage to DNA correlates inversely with life span of mammals.
I humans have the longest life span of mammalian species and consume more energy over their life span on a per weight basis (I).
These data indicate that aging rate is related to metabolic rate or the rate oxygen is utilized per unit weight of tissue.
oxygen species could represent a class of longevity determinant processes This conclusion leads co the prediction that longevity would be governed by processes acting co stabilize proper gene expression and thus the stability of the differentiated cell.

This so-called "spontaneous combustion" phenomena makes the use of certain terpene solvents difficult or even dangerous.
While traditional antioxidants like BHT and tocopherol can often provide adequate protection, these additives are only effective in applications where exposure to air is limited (e.g. blending).
More robust antioxidant systems are required to protect delicate terpene hydrocarbons in severe industrial environments (in separate testing terpinolene was found to be the most reactive of all commercially available terpene solvents).
Based on lab research supported by extensive field-testing, T2 Labs has developed a safe, economical additive that virtually prevents destructive oxidation under anticipated conditions.
The appearance of the filter is recorded after 72 hours.

AICR Ever Green, Ever Healthy Feature August 2002 Topic: Cancer by the American Institute for Cancer Research Researchers still have a great deal to learn about how antioxidants in foods work in the body and how they impact cancer.
Blueberries Why do health experts recommend obtaining antioxidants through food rather than supplements?
According to a test that measures the oxygen radical absorbance capacity (ORAC) -- the antioxidant potency -- prunes have the highest score, followed by blueberries, oranges and broccoli florets.
Although all plant foods provide antioxidants, brightly colored vegetables and fruits have the highest ORAC measurements.
Look for bright reds, greens, oranges, blues, purples and yellows.

Reactive oxygen intermediates mediate brain injury in bacterial meningitis.
The present study evaluated whether these antioxidants are beneficial in a model of pneumococcal meningitis.
Starting 18 h after infection, the animals were treated subcutaneously with 100 mg/kg ceftriaxone.
Previous studies found that neurons in the dentate granule cells of the hippocampus undergo apoptosis during experimental bacterial meningitis, independent of ischemic damage.
In summary, using a model of bacterial meningitis caused by S. pneumoniae, we demonstrated a beneficial effect of treatment with the antioxidants NAC, DFO, and TLM on cortical injury, whereas the drugs were not efficacious in preventing hippocampal injury.

Sensitive and selective liquid chromatography methods with multi-channel electrochemical detection have been developed for determining many of these compounds in extracts and in biological samples.
The separated components can then be analyzed at up to four different electrodes set at four different voltages simultaneously.
This method provides additional ability to identify substances because one has not only the optimal voltage for a particular compound but the ratios of peak areas or heights at different voltages, which can also be used as an identification tool.
These methods have been developed at BAS for the Analytical Core of the Purdue University Botanical Center on Age Related Diseases.

A very important companion intervention to lowering the blood cholesterol level is to provide adequate antioxidants such as those found in red wine.
Vitamin C is limited to the water compartments and vitamin E to the fat compartments.
2. It is the oxidation of the low density lipoprotein (LDL), with its high cholesterol content, which initiates the processes leading to the accumulation of fatty deposits in blood vessel walls (i. e., atherosclerosis).
Therefore, it is very important to have adequate quantities of antioxidants to minimize the damage by free radicals to these very important fats, the polyunsaturated fatty acids and cholesterol.
