The present paper summarises current evidence for the influence of dose rate upon radiation-related effects. Endpoints considered include molecular, cellular, organism, and human studies. Emphasis will be placed on dose rates relevant for radiological protection settings. We focus on low linear-energy-...
But even these robust beasts pale in comparison to a microscopic animal that is one of the toughest creatures ever to exist. This tiny organism has been on Earth for around 600 million years, meaning it both existed before and outlived dinosaurs. It is so adaptable that it's basically indes...
The mechanisms by which DR increases longevity are not fully identified in any organism. The widespread extension of lifespan by reduced nutrient intake is suggestive of evolutionary conservation of mechanisms but could also result from convergent evolution. As well as extending lifespan, reduced IIS ...
of how this network of genes plays a role in protection from cancers, therapy and integrating the homeostatic mechanisms of stress management and fidelity in a cell and organism. The goal of this chapter is to elucidate some of those questions and suggest new directions for this area of ...
Prokaryotes are tiny and simple compared to eukaryotes; their cells are correspondingly less complex. In most cases, a prokaryotic cell is the same thing as a prokaryotic organism, and the energy needs of a bacteria are far lower than those of any eukaryotic cell. ...
The further you get from the Antarctic coastline, the more extreme the polar desert conditions become, but in the interior, a unique lifeform thrives: lichen, a plantlike organism formed by a symbiotic partnership between an alga and a fungus. Antarctica is home to hundreds of species of lich...
The huge coral is located in the Coral Triangle region (so named because of its coral variety) of the Three Sisters group of islands, nearly 13 meters (42 feet) underwater. This specific organism is not a coral reef because it only consists of one coral species, Pavona clavus, rather tha...
Protein synthesis is an important process in all eukaryotic cells, as the protein forms structural components of each cell and is essential for life. Protein is often called the building block of cells. Three main forms of RNA exist — messenger RNA, transfer RNA and ribosomal RNA. The DNA ...
Genotype consisting of two different parts. A human blood type AB is an example of a heterozygous genotype. 9 Homozygous Same allele presence on both chromosomes. Homozygous conditions are crucial for certain genetic screenings. 7 Heterozygous Mixed genetic traits in an organism. Heterozygous animals...
To raise, as any kind of stock. Strain (biology) A particular variety of a microbe, virus, or other organism, usually a taxonomically infraspecific one. They say this year's flu virus is a particularly virulent
