Plasmids
|
D010957 |
[Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS.

|
Plasminogen
|
D010958 |
[Precursor of plasmin (FIBRINOLYSIN). It is a single-chain beta-globulin of molecular weight 80-90,000 found mostly in association with fibrinogen in plasma; plasminogen activators change it to fibrinolysin. It is used in wound debriding and has been investigated as a thrombolytic agent.

Plasminogen Activator Inhibitor 1
|
D017395 |
[A member of the serpin family of proteins. It inhibits both the tissue-type and urokinase-type plasminogen activators.
] |
|
Plasminogen Activator Inhibitor 2
|
D017396 |
[Member of the serpin family of proteins. It inhibits both the tissue-type and urokinase-type plasminogen activators.

|
Plasminogen Activators
|
D010960 |
[A heterogeneous group of proteolytic enzymes that convert PLASMINOGEN to FIBRINOLYSIN. They are concentrated in the lysosomes of most cells and in the vascular endothelium, particularly in the vessels of the microcirculation.

|
Plasminogen Inactivators
|
D015849 |
[Important modulators of the activity of plasminogen activators. The inhibitors belong to the serpin family of proteins and inhibit both the tissue-type and urokinase-type plasminogen activators.

|
Plasmodesmata
|
D031425 |
[Membrane-like channels of cytoplasm connecting adjacent plant cells. Plasmodesmata connect through pores in the CELL WALL and associate with the CYTOSKELETON machinery. They are essential for intercellular transport and communication.

|
Plasmodiophorida
|
D056909 |
[A group of EUKARYOTES that are parasites of plants. Life cycle stages include zoospores and plasmodia.

|
Plasmodium
|
D010961 |
[A genus of protozoa that comprise the malaria parasites of mammals. Four species infect humans (although occasional infections with primate malarias may occur). These are PLASMODIUM FALCIPARUM; PLASMODIUM MALARIAE; PLASMODIUM OVALE, and PLASMODIUM VIVAX. Species causing infection in vertebrates other than man include: PLASMODIUM BERGHEI; PLASMODIUM CHABAUDI; P. vinckei, and PLASMODIUM YOELII in rodents; P. brasilianum, PLASMODIUM CYNOMOLGI; and PLASMODIUM KNOWLESI in monkeys; and PLASMODIUM GALLINACEUM in chickens.

Plasmodium berghei
|
D010962 |
[A protozoan parasite of rodents transmitted by the mosquito Anopheles dureni.
] |
|
Plasmodium chabaudi
|
D016788 |
[A protozoan parasite of rodents transmitted by the mosquito Anopheles stephensi.
] |
|
Plasmodium cynomolgi
|
D016789 |
[A protozoan parasite that occurs naturally in the macaque. It is similar to PLASMODIUM VIVAX and produces a type of malaria similar to vivax malaria (MALARIA, VIVAX). This species has been found to give rise to both natural and experimental human infections.
] |
|
Plasmodium falciparum
|
D010963 |
[A species of protozoa that is the causal agent of falciparum malaria (MALARIA, FALCIPARUM). It is most prevalent in the tropics and subtropics.
] |
|
Plasmodium gallinaceum
|
D010964 |
[A protozoan parasite that causes avian malaria (MALARIA, AVIAN), primarily in chickens, and is transmitted by the Aedes mosquito.
] |
|
Plasmodium knowlesi
|
D016790 |
[A protozoan parasite from Southeast Asia that causes monkey malaria. It is naturally acquired by man in Malaysia and can also be transmitted experimentally to humans.
] |
|
Plasmodium malariae
|
D010965 |
[A protozoan parasite that occurs primarily in subtropical and temperate areas. It is the causal agent of quartan malaria. As the parasite grows it exhibits little ameboid activity.
] |
|
Plasmodium ovale
|
D041122 |
[A species of protozoan parasite causing MALARIA. It is the rarest of the four species of PLASMODIUM infecting humans, but is common in West African countries and neighboring areas.
] |
|
Plasmodium vivax
|
D010966 |
[A protozoan parasite that causes vivax malaria (MALARIA, VIVAX). This species is found almost everywhere malaria is endemic and is the only one that has a range extending into the temperate regions.
] |
|
Plasmodium yoelii
|
D010967 |
[A species of PLASMODIUM causing malaria in rodents.
] |
|
Plastic Embedding
|
D016613 |
[The infiltrating of histological specimens with plastics, including acrylic resins, epoxy resins and polyethylene glycol, for support of the tissues in preparation for sectioning with a microtome.
