Test for cell-mediated antitumor immunity and related serum blocking factors based on the finding that leukocytes from cancer patients, but not from controls, when mixed in vitro with antigenic extracts of tumors of the same histological type, undergo a diminution in their normal adherence to glass surfaces. Sera from tumor-bearing patients block the LAI reaction of their own leukocytes or those of other patients with the same type of tumor.

Techniques used to demonstrate or measure an immune response, and to identify or measure antigens using antibodies.

Proteins, glycoprotein, or lipoprotein moieties on surfaces of tumor cells that are usually identified by monoclonal antibodies. Many of these are of either embryonic or viral origin.

Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)

The qualitative or quantitative estimation of the likelihood of adverse effects that may result from exposure to specified health hazards or from the absence of beneficial influences. (Last, Dictionary of Epidemiology, 1988)

(LA) is not a medical term; it is a region, specifically the second most populous city in the United States, located in Southern California, which contains several world-renowned hospitals and medical centers that offer advanced healthcare services and cutting-edge medical research.

The maximum exposure to a biologically active physical or chemical agent that is allowed during an 8-hour period (a workday) in a population of workers, or during a 24-hour period in the general population, which does not appear to cause appreciable harm, whether immediate or delayed for any period, in the target population. (From Lewis Dictionary of Toxicology, 1st ed)

Time period from 1801 through 1900 of the common era.

Time period from 1901 through 2000 of the common era.

The study of aquatic life inhabiting bodies of water, including growth, morphology, physiology, genetics, distribution, and interactions with other organisms and the environment. It includes MARINE HYDROBIOLOGY.

The veins and arteries of the HEART.

An ACUTE PHASE REACTION protein present in low concentrations in normal sera, but found at higher concentrations in sera of older persons and in patients with AMYLOIDOSIS. It is the circulating precusor of amyloid A protein, which is found deposited in AA type AMYLOID FIBRILS.

Individual's rights to obtain and use information collected or generated by others.

Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.

A group of cell-surface receptors for oxidatively modified LOW-DENSITY LIPOPROTEINS. The group includes certain SCAVENGER RECEPTORS that contribute to the pathogenesis of ATHEROSCLEROSIS by uptake of oxidized LDL.

A publication issued at stated, more or less regular, intervals.

Adherence of cells to surfaces or to other cells.
