A plasmoid is a coherent structure of plasma and magnetic fields. Plasmoids have been proposed to explain natural phenomena such as ball lightning , [ 1 ] [ 2 ] magnetic bubbles in the magnetosphere , [ 3 ] and objects in cometary tails, [ 4 ] in the solar wind, [ 5 ] [ 6 ] solar atmosphere, [ 7 ] and in the heliospheric current sheet .

2019年4月11日 · Plasmodium have a fairly typical eukaryote cell membrane, but also have several surface structures including rhoptries containing parasite proteins and micronemes that contain specialized proteins used for adhesion to host cell bodies as well as for motility. These surface structures are actually semi protruding organelles.

2022年3月13日 · Plasmids are small circular DNA fragments, double-stranded, self-replicating extra chromosomal structures found in many microorganisms. The term Plasmid was coined by Joshua Lederberg in 1952. Plasmids are important as genetic tools, which are used to introduce, manipulate or delete certain genes from the host cell.

2003年12月26日 · Plasmodium is distinguished by the presence of numerous low complexity inserts within globular domains of proteins. It displays several peculiarities in its transcription apparatus, and its DNA repair system appears to favor a certain innate level of mutability. Plasmodium possesses many cell surface molecules with “animal-like” adhesion modules.

A plasmodium is an amoeboid, multinucleate, and naked mass of cytoplasm that contains many diploid nuclei. The resulting structure, a coenocyte, is created by many nuclear divisions without the process of cytokinesis, which in other organisms pulls newly-divided cells apart. [1] .

Plasmodium is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. The life cycles of Plasmodium species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal.

Summary of key plasmid properties including interaction with the chromosome (a), vertical inheritance via vegetative replication (b) and horizontal transfer to different bacteria (c). As much as possible is explained by labelling on the Figure.

Plasmas with nonuniformities, such as density or temperature striations in the direction parallel to the magnetic field, are of fundamental interest. They occur, for example, in the ionosphere and in the aurora.

a plasmoid - a giant bubble of hot mag­ netized gas - into interplanetary space. The existence of plasmoids was confirmed in 1984 through satellite data and their

Plasmodium scavenges host lipids for development and maturation. Plasmodium parasites extensively alter their host hepatocyte to evade host detection and support an unprecedented replication rate.
