The Individual

1. Observations on tissue cultures of heart muscle from chicken embryos indicate that in general the growth rate of the individual cells decreases with age. The negative acceleration of growth is greatest at the beginning of life as in the intact embryo. 2. The latent period before growth commences increases with the age of the implanted tissue, but in a different fashion. The acceleration of the latent period is greatest near the end of the incubation period, thus demonstrating that the factors determining the initiation of growth and those determining the extent of growth are not similar.

Production Conditions

Innovators of in vitro meat (IVM) are convinced that this approach is the solution for problems related to current meat production and consumption, especially regarding animal welfare and environmental issues. However, the production conditions have yet to be fully clarified and there is still a lack of ethical discourses and critical debates on IVM. In consequence, discussion about the ethical justifiability and desirability of IVM remains hypothetical and we have to question those promises. This paper addresses the complex ethical aspects associated with IVM and the questions of whether, and under what conditions, the production of IVM represents an ethically justifiable solution for existing problems, especially in view of animal welfare, the environment, and society. There are particular hopes regarding the benefits that IVM could bring to animal welfare and the environment, but there are also strong doubts about their ethical benefits.

Exact Temperature

SummaryTemperature represents a very important variable in ADP-induced platelet aggregation.When low doses of ADP ( < 1 (μM) are used to induce platelet aggregation, the length of the incubation period of PRP in the cuvette holder of the aggregometer, thermostatted at 37° C, is very critical. Samples of the same PRP previously kept at room temperature, were incubated for increasing periods of time in the cuvette of the aggregometer before adding ADP, and a significant decrease of aggregation, proportional to the length of incubation, was observed. Stirring of the PRP during the incubation period made these changes more evident.To measure the exact temperature of the PRP during incubation in the aggre- gometer, a thermocouple device was used. While the temperature of the cuvette holder was stable at 37° C, the PRP temperature itself increased exponentially, taking about ten minutes from the beginning of the incubation to reach the value of 37° C. The above results have a practical significance in the reproducibility of the platelet aggregation test in vitro and acquire particular value when the effect of inhibitors of ADP induced platelet aggregation is studied.Experiments carried out with three anti-aggregating agents (acetyl salicyclic acid, dipyridamole and metergoline) have shown that the incubation conditions which influence both the effect of the drugs on platelets and the ADP breakdown in plasma must be strictly controlled.
