Strain (injury)

A strain is an injury to a muscle in which the muscle fibers tear as a result of overstretching. A strain is also colloquially known as a pulled muscle or torn muscle. The equivalent injury to a ligament is a sprain.

Signs and symptoms

Typical symptoms of a strain include localized stiffness, discoloration and bruising around the strained muscle.

Causes

Strains are a result of muscular fiber tears due to over stretching; they can range from mild annoyance to very painful. Although strains are not restricted to athletes and can happen while doing everyday tasks, people who play sports are more at risk of developing a strain.

Treatment

The first-line treatment for a muscular strain in the acute phase include five steps commonly known as P.R.I.C.E.

Strain (biology)

In biology, a strain is a low-level taxonomic rank used in three related ways, usually at the infraspecific level (within a species).

Microbiology or virology

A strain is a genetic variant or subtype of a micro-organism (e.g., virus or bacterium or fungus). For example, a "flu strain" is a certain biological form of the influenza or "flu" virus. Compare clade.

Plants

The term has no official ranking status in botany; the term refers to the collective descendants produced from a common ancestor that share a uniform morphological or physiological character. A strain is a designated group of offspring that are either descended from a modified plant (produced by conventional breeding or by biotechnological means), or which result from genetic mutation.

As an example, some rice strains are made by inserting new genetic material into a rice plant, all the descendants of the genetically modified rice plant are a strain with a unique genetic code that is passed on to later generations; the strain designation, which is normally a number or a formal name, covers all the plants that descend from the originally modified plant. The rice plants in the strain can be bred to other rice strains or cultivars, and if desirable plants are produced, these are further bred to stabilize the desirable traits; the stabilized plants that can be propagated and "come true" (remain identical to the parent plant) are given a cultivar name and released into production to be used by farmers.

Strain (manga)

Strain (ストレイン) is manga series written by Yoshiyuki Okamura and illustrated by Ryoichi Ikegami, published Shogakukan's Big Comic Superior from 1996 to 1998.
