Autogenous vaccines, also called autologous vaccines, autovaccines, “self” or custom vaccines, are vaccines that are prepared by isolation and destruction of microorganisms in infected individuals and used to provide immunity to the same individual. [1][2] Autogenous vaccines were introduced in the early twentieth century with growing ...
Elements. The main elements that comprise the human body (including water) can be summarized as CHNOPS. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.
Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person (auto- meaning "self" in Greek [1]). The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant.
The term autogenous, from the Greek root auto-("self"), describes how the individual who receives the graft is the same individual who provides the donor tissue. [ 3 ] The connective tissue is generally taken from the hard palate , although it may be taken from other sites as well, such as the maxillary tuberosity area.
A surgeon places a bone graft into position during a limb salvage. Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk ...
Autologous stem-cell transplantation (also called autogenous, autogenic, or autogenic stem-cell transplantation and abbreviated auto-SCT) is the autologous transplantation of stem cells [1][2][3][4] —that is, transplantation in which stem cells (undifferentiated cells from which other cell types develop) are removed from a person, stored, and ...
Autogenous healing is the natural ability of cementitious materials to repair cracks. This ability is principally attributed to further hydration of unhydrated cement particles and carbonation of dissolved calcium hydroxide. [107] Cementitious materials in fresh-water systems can autogenously heal cracks up to 0.2 mm over a period of 7 weeks. [108]
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ. Accordingly, organs are formed by the functional grouping together of multiple tissues. [3]
