transfer factor

 (TF)
a factor occurring in sensitized lymphocytes that has the capacity to transfer delayed hypersensitivity to a normal (nonreactive) individual. It confers cell-mediated immunity and therefore has been found to be useful in treating conditions in which there is a disorder of immune response. As an adjunct to antibiotic therapy it is useful in the treatment of such antibiotic-resistant diseases as candidiasis, coccidioidomycosis, and leprosy.

trans·fer fac·tor

1. the transfer gene of a conjugative plasmid, especially of the resistance plasmid;
2. a dialyzable extract that is obtained from the leukocytes of a person with a delayed-type sensitivity and that, after injection into the skin of a nonsensitive person, transfers the specific sensitivity to the recipient;
3. Synonym(s): elongation factor

transfer factor

n.
Any of various small proteins that are obtained from donors with cell-mediated immunity to certain antigens and can confer this immunity when given to nonimmune recipients.

transfer factor (TF)

a leukocyte extract that transfers delayed hypersensitivity from one person to another. Transfer factor has been studied for its possible use in the treatment of chronic mucocutaneous candidiasis and Wiskott-Aldrich syndrome and as a means of transferring antitumor immunity to patients with various types of cancer.

1. The transfer gene of a conjugative plasmid, especially of the resistance plasmid.
2. A dialyzable extract that is obtained from the leukocytes of a person with a delayed-type sensitivity and that, following injection into the skin of a nonsensitive person, transfers the specific sensitivity to the recipient.
3. Synonym(s): elongation factor.

transfer factor

A LYMPHOKINE released by T cells that activates MACROPHAGES and prompts them to attack fungi.

transfer factor,

n a natural protein that is used to treat bacterial and viral diseases postulated to transfer im-munity from one cell to another, thereby boosting immune function.

transfer factor

a factor extractable from sensitized lymphocytes of some species that has the capacity to transfer delayed hypersensitivity to a normal (nonreactive) individual; abbreviated TF. It confers cell-mediated immunity and therefore has been found to be useful in treating conditions in which there is a disorder of immune response. As an adjunct to antibiotic therapy it has been used in the treatment of such antibiotic-resistant diseases as candidiasis and coccidioidomycosis.

In the program CORA, used for thermodynamic loss analysis, a so called wall heat transfer factor exists, which multiplies the calculated wall heat quantity by a factor.
The influence of the wall heat transfer factor can be estimated by comparing the wall heat transfer coefficient without and with adjustment.
Variations in transfer factor among the different vegetables may be attributed to differences in the concentration of metals in the soil and differences in element uptake by different vegetables [28].
Hence, most of the metals might be affected by anthropogenic activities based on the transfer factor calculated in the current study.
The average transfer factor of the selected heavy metals and metalloids were calculated as the concentration of metals and metalloids in tissues of vegetable related to concentrations in the soil.
With regard to transfer factors, Mohan and Lo (1985) suggest that there are both positive and negative transfers in L2 academic writing.
In our analysis, we focused on or looked for developmental factors and transfer factors as proposed by Mohan and Lo (1985), and further following their theoretical framework, we considered the context of the participants' academic, linguistic, cultural, and educational background.
Mohan and Lo (1985) suggested that a general model of L2 composition should include both developmental and transfer factors.
Generally, transfer factor within the organs was less than one.

The transfer factor from soil to forage was calculated using Microsoft excel by the following formula: and from forage to hairs by following formula: Similarly from forage to feces by the following formula:
Under both treatments, the transfer factor for Mo in soil-forage varied from 4.
