Putrefaction is the fifth stage of death, following pallor mortis, livor mortis, algor mortis, and rigor mortis. This process references the breaking down of a body of an animal post-mortem . In broad terms, it can be viewed as the decomposition of proteins , and the eventual breakdown of the cohesiveness between tissues, and the liquefaction ...
The rabbit test became a widely used bioassay (animal-based test) to test for pregnancy. The term "rabbit test" was first recorded in 1949, and was the origin of a common euphemism, "the rabbit died", for a positive pregnancy test. [4] The phrase was, in fact, based on a common misconception about the test.
The hCG test can be used to screen for uterus cancer, or a molar pregnancy, which is when there is abnormal placental growth in the uterus. [9] The hCG test can also be done after a miscarriage to ensure that a molar pregnancy is not present. In men, the hCG test can be used to screen for the presence of testicular cancer. [9]
Putrefying bacteria play a key role in decomposing and fermenting substances within the body as well as the body itself after death. Putrefaction is defined as the final step of decomposition after death. [3] Because these bacteria play a role in decomposition after death, putrefying bacteria also play a key role in the nitrogen cycle.
The control line of this pregnancy test is blank, making the test invalid. The control line on the left of this pregnancy test is visible, suggesting that the test result is valid. A pale purple line has also appeared on the right hand side (the test line) which clearly signifies that the subject is pregnant.
Autolysis and putrefaction are the main processes responsible for the decomposition of remains. [ 1 ] In the healing of wounds, autolytic debridement can be a helpful process, where the body breaks down and liquifies dead tissue so that it can be washed or carried away.
During later stages of decomposition, more resistant tissue proteins are degraded by the effects of putrefaction. These include: reticulin; muscle protein; collagen (a hard tissue protein), which survives even longer than the former tissue proteins [4] Keratin is a protein which is found in skin, hair, and nails.
Spalding's sign is a sign used in obstetrics. [1] It is named for Alfred Baker Spalding. [2] [3]It is an indicator of fetal death. [4] When fetal death has occurred loss of alignment and overriding of the bones of cranial vault occur due to shrinkage of cerebrum, [5] abdominal sonar examination may reveal an overriding of the fetal cranial bones.
