Cryopreservation is a hallmark method for fungi that do not sporulate (otherwise other preservation methods for spores can be used at lower costs and ease), sporulate but have delicate spores (large or freeze-dry sensitive), are pathogenic (dangerous to keep metabolically active fungus) or are to be used for genetic stocks (ideally to have an ...
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. [1] [2] Cryonics is regarded with skepticism by the mainstream scientific community.
The history of plant cryopreservation started in 1965 when Hirai was studying the biology activities that happened when biological samples were frozen. [1] Three years later, there was the first successful attempt cryopreserving callus cells. [1]
Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...
Women with a family history of early menopause may have an interest in fertility preservation to preserve viable eggs that could deteriorate at an earlier onset. Those with ovarian diseases such as Polycystic Ovary Syndrome could opt for this method. [citation needed] Oocyte cryopreservation is one of many options for individuals undergoing IVF ...
Cryonics, the low-temperature preservation of people who cannot be sustained by contemporary medicine; Cryoprecipitate, a blood-derived protein product used to treat some bleeding disorders; Cryotherapy, medical treatment using cold Cryoablation, tissue removal using cold; Cryosurgery, surgery using cold
Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples. [2]
A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic ...
