All terms in MESH

Label	Id	Description
Hemostatics	D006490	[Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure.]
Fibrin Modulating Agents	D050299	[Agents that affect the function of FIBRIN in BLOOD COAGULATION. They used as COAGULANTS for HEMORRHAGE or ANTICOAGULANTS for THROMBOSIS.]
Antifoaming Agents	D000934	[Agents used to prevent the formation of foam or to treat flatulence or bloat.]
Surface-Active Agents	D013501	[Agents that modify interfacial tension of water; usually substances that have one lipophilic and one hydrophilic group in the molecule; includes soaps, detergents, emulsifiers, dispersing and wetting agents, and several groups of antiseptics.]
Antifungal Agents	D000935	[Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues., Antibiotics inhibiting the growth of or killing fungi and used in the treatment of various fungal diseases.]
Antigen-Antibody Complex	D000936	[The complex formed by the binding of antigen and antibody molecules. The deposition of large antigen-antibody complexes leading to tissue damage causes IMMUNE COMPLEX DISEASES.]
Antigens	D000941	[Substances that are recognized by the immune system and induce an immune reaction.]
Antigen-Presenting Cells	D000938	[A heterogeneous group of immunocompetent cells that mediate the cellular immune response by processing and presenting antigens to the T-cells. Traditional antigen-presenting cells include MACROPHAGES; DENDRITIC CELLS; LANGERHANS CELLS; and B-LYMPHOCYTES. FOLLICULAR DENDRITIC CELLS are not traditional antigen-presenting cells, but because they hold antigen on their cell surface in the form of IMMUNE COMPLEXES for B-cell recognition they are considered so by some authors.]
Antigenic Variation	D000940	[Change in the surface ANTIGEN of a microorganism. There are two different types. One is a phenomenon, especially associated with INFLUENZA VIRUSES, where they undergo spontaneous variation both as slow antigenic drift and sudden emergence of new strains (antigenic shift). The second type is when certain PARASITES, especially trypanosomes, PLASMODIUM, and BORRELIA, survive the immune response of the host by changing the surface coat (antigen switching). (From Herbert et al., The Dictionary of Immunology, 4th ed), Antigenic variation as the pathogen passes through an entire host population rather than just a single host.]
Antigens, Bacterial	D000942	[Substances elaborated by bacteria that have antigenic activity.]
Biomarkers	D015415	[Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, ENVIRONMENTAL EXPOSURE and its effects, disease diagnosis; METABOLIC PROCESSES; SUBSTANCE ABUSE; PREGNANCY; cell line development; EPIDEMIOLOGIC STUDIES; etc.]
Antigens, Differentiation, B-Lymphocyte	D000944	[Membrane antigens associated with maturation stages of B-lymphocytes, often expressed in tumors of B-cell origin.]
Antigens, Fungal	D000946	[Substances of fungal origin that have antigenic activity.]
Antigens, Helminth	D000947	[Any part or derivative of a helminth that elicits an immune reaction. The most commonly seen helminth antigens are those of the schistosomes.]
Histocompatibility Antigens Class II	D000949	[Large, transmembrane, non-covalently linked glycoproteins (alpha and beta). Both chains can be polymorphic although there is more structural variation in the beta chains. The class II antigens in humans are called HLA-D ANTIGENS and are coded by a gene on chromosome 6. In mice, two genes named IA and IE on chromosome 17 code for the H-2 antigens. The antigens are found on B-lymphocytes, macrophages, epidermal cells, and sperm and are thought to mediate the competence of and cellular cooperation in the immune response. The term IA antigens used to refer only to the proteins encoded by the IA genes in the mouse, but is now used as a generic term for any class II histocompatibility antigen.]
Histocompatibility Antigens	D006649	[A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection.]
Antigens, Polyomavirus Transforming	D000952	[Polyomavirus antigens which cause infection and cellular transformation. The large T antigen is necessary for the initiation of viral DNA synthesis, repression of transcription of the early region and is responsible in conjunction with the middle T antigen for the transformation of primary cells. Small T antigen is necessary for the completion of the productive infection cycle.]
Antigens, Viral, Tumor	D000957	[Those proteins recognized by antibodies from serum of animals bearing tumors induced by viruses; these proteins are presumably coded for by the nucleic acids of the same viruses that caused the neoplastic transformation.]
Oncogene Proteins, Viral	D009856	[Products of viral oncogenes, most commonly retroviral oncogenes. They usually have transforming and often protein kinase activities.]
Antigens, Protozoan	D000953	[Any part or derivative of any protozoan that elicits immunity; malaria (Plasmodium) and trypanosome antigens are presently the most frequently encountered.]
