Technicians preparing a body for cryopreservation in 1985. Cryonics (from Greek: κρύος kryos, meaning "cold") is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of human remains in the hope that resurrection may be possible in the future.
Grade 2: if there is a lesion on the distal body part, tissue and fingernails can be destroyed Grade 3: if there is a lesion on the intermediate or near body part, auto-amputation and loss of function can occur Grade 4: if there is a lesion very near the body (such as the carpals of the hand), the limb can be lost.
The frozen section procedure as practiced today in medical laboratories is based on the description by Dr Louis B. Wilson in 1905. Wilson developed the technique from earlier reports at the request of Dr William Mayo, surgeon and one of the founders of the Mayo Clinic [3] Earlier reports by Dr Thomas S. Cullen at Johns Hopkins Hospital in Baltimore also involved frozen section, but only after ...
Cryopreservation or cryoconservation is a process where biological material - cells, tissues, or organs - are frozen to preserve the material for an extended period of time. [1] At low temperatures (typically −80 °C (−112 °F) or −196 °C (−321 °F) using liquid nitrogen ) any cell metabolism which might cause damage to the biological ...
The eggs are subsequently removed from the body by transvaginal oocyte retrieval. The procedure is usually conducted under sedation. The eggs are immediately frozen. [5] The egg is the largest cell in the human body and contains a large amount of water. When the egg is frozen, the ice crystals that form can destroy the integrity of the cell. To ...
In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food). In this case, food items are subjected to temperatures well below [clarification needed] the freezing point of water. Thus, smaller ice crystals are formed, causing less damage to cell membranes. [3]
Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. [3] It is used to treat conditions in which there are low blood clotting factors (INR > 1.5) or low levels of other blood proteins. [3] [1] It may also be used as the replacement fluid in plasma exchange.
