Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Ultraviolet lasers can also be made by applying frequency conversion to lower-frequency lasers. [citation needed] Ultraviolet lasers have applications in industry (laser engraving), medicine (dermatology, and keratectomy), chemistry , free-air secure communications, computing (optical storage), and manufacture of integrated circuits.
Prophylactic surgery (also known as preventive surgery or risk-reducing surgery), is a form of surgery, the purpose of which is to minimize or prevent the risk of developing cancer in an organ or gland that has yet to develop the disease. This can be a life-saving procedure for those most at risk of developing cancer in certain organs of their ...
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 ...
Zoetron therapy – therapy based around a large electromagnetic device that emitted a weak field which, it was claimed, could kill cancer cells. Patients were charged US$15,000 up-front for treatment in Mexican clinics. In 2005 criminal charges were brought against the owners of the company making the device for their claims of its worth.

Cancer patients undergo many obstacles and one of these includes mental strain. It is very common for cancer patients to become stressed, overwhelmed, uncertain, and even depressed. [46] The use of chemo is a very harsh treatment causing the cells of the body to die.
The use of autologous cells in microencapsulation therapy is limited by the availability of these cells and even though xenogeneic cells are easily accessible, danger of possible transmission of viruses, especially porcine endogenous retrovirus to the patient restricts their clinical application, [67] and after much debate several groups have ...
Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
