A technique for the study of myogenesis in vitro
Experimental Cell Research, 1958THE differentiation into muscle elements of cells originating in explants of embryonic muscle tissue has been repeatedly studied. The literature has recently been reviewed by Godman [2] and individual references will not be given here. In the case to be described differentiation was both constant and rapid and the method may be suitable for studies of ...

The Continuous Evolution In Vitro Technique
Current Protocols in Nucleic Acid Chemistry, 2010AbstractIn vitro experimentation techniques were developed in response to the necessity of exploring new molecular structures and functions and to better understand evolutionary phenomena that shape organismal and molecular populations. The advancement of these techniques has allowed further exploration of more complicated evolutionary dynamics.

In Vivo and In Vitro Starch Digestion: Are Current in Vitro Techniques Adequate?
Biomacromolecules, 2010The time evolution of the size distributions of (fully branched and debranched) starch molecules during in vivo and in vitro digestion was analyzed using size exclusion chromatography (SEC) and compared. In vivo digesta were collected from the small intestine of pigs fed with raw normal maize starch; in vitro digestion was carried out on the same diet ...

A Technique for Studying Sperm Maturation in vitro
Nature, 1972IN mammals spermatozoa mature while passing through the epididymis. In the rabbit there are virtually no fertile spermatozoa in the caput epididymidis and fertilizing ability is acquired when, the spermatozoa pass through the corpus epididymidis1,2. Spermatozoa retained by ligatures, in the proximal corpus develop a normal fertilizing ability in 24 h ...

The in vitro micronucleus technique
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2000The study of DNA damage at the chromosome level is an essential part of genetic toxicology because chromosomal mutation is an important event in carcinogenesis. The micronucleus assays have emerged as one of the preferred methods for assessing chromosome damage because they enable both chromosome loss and chromosome breakage to be measured reliably ...

In Vitro Clotting Technique for Hemodialysis Circuits
ASAIO Journal, 1999Physiologic clotting of a dialysis circuit was achieved using an in vitro method. The closed loop method used a circuit filled with defibrinated bovine blood. To achieve clotting, a slow infusion (5-15 ml/hr) of ACD bovine plasma was performed. The rate and amount of infusion of the plasma allowed for careful control of the amount of clotting in the ...

In vitro skin permeation techniques
Journal of Controlled Release, 1992Abstract This paper reviews various techniques used to assess permeation of drugs into and through skin under in vitro conditions. There have been a wide variety of diffusion cells designed for in vitro measurement of skin permeation. These cells have generally been designed in one of two ways: side-by-side (bichambers) and vertical in vivo mimic ...
