Neutron Kerma factor, and water equivalence of some tissue substitutes
(Universidad Autónoma Metropolitana, 2014-04)
The kerma factors and kerma relative to air and water of 24 compounds used as
tissue substitutes were calculated for neutron energy from 2.53x10-8 up to 29 MeV.
The kerma ratio of the tissue substitutes relative to air ...
X- and γ-ray interaction characteristics of Griffith, Alderson, Frigerio, Goodman and Rossi tissue substitutes
(Sociedad Mexicana de Irradiación y Dosimetría, 2015-09-30)
Detailed information of radiation interaction, exposure and dose delivery to tissue substitutes is necessary for various branches of radiation physics. In the present investigation X- and γ-ray interaction characteristics ...
Characterization of α-actin isoforms in white and red skeletal muscle types of Leporinus macrocephalus (Characiformes, Anostomidae)
(2015-10-01)
Two α-actin genes of the fish Leporinus macrocephalus, referring to white and red muscle tissues, were isolated. Actin isoforms, that mainly differed by a Ser/Ala155 substitution, can have a functional significance related ...

Calcium sulfate and PTFE nonporous barrier for regeneration of experimental bone defects
(Medicina Oral S L, 2008-06-01)
The aim of the study was to evaluate the possibility to obtain guided bone regeneration with two types of physical barriers (calcium sulfate and PTFE nonporous barrier) in surgical defects created in rat parietal bones. ...
The use of adipose tissue-derived stem cells within a dermal substitute improves skin regeneration by increasing neoangiogenesis and collagen synthesis
(2012)
BACKGROUND: Surgical treatment of injuries with loss of skin tissue has improved significantly with the advent of regenerative medicine and tissue bioengineering, and the use of stem cells and dermal substitutes. The success ...
Effects of fibrin sealer and resorbable gelatin on the repair of osseous defects in rat tibia
(2007-12-01)
Gelfoam® - a biologically resorbable gelatin sponge - has the function of restricting hemorrhage, providing platelet rupture, and supporting fibrin threads. Beriplast® - a fibrinogen-thrombin compound - is used to adhere ...
