OUR KILLING HEAT

Are our commonest killing diseases preventable?

Identity, killing, and the boundaries of our existence.

We all agree that it is generally wrong to kill persons. Although we may differ over exceptions, and over which beings qualify as persons, the judgment that it is wrong, other things equal, intentionally to kill paradigm persons represents common moral ground. At the same time, there is profound disagreement regarding the ethics of killing-or allowing to die-those beings whose moral status is l...

Are We Killing Our Fat Cells before Grafting Them?

S ince its inception by Neuber in 1893, there have been numerous modifications in fat grafting techniques , all attempting to maximize posttransplant adipocyte survival. Despite ongoing research, there remains wide variations in viability after autologous fat grafting, with reported loss ranging from 40% to 60%. 1 Research studying various methods of harvesting , force and time of centrifugatio...

Protection against heat-induced cell killing by polyols in vitro.

The polyols erythritol and adonitol reduced 45 degrees heat killing in asynchronous Chinese hamster ovary cells. Heat protection by glycerol and erythritol increased with the apparent intracellular concentration, as inferred from cell volume measurements, and the number of hydroxyl groups per alcohol molecule. The nonlinear tetrahydroxy alcohol pentaerythritol did not protect but sensitized to ...

The efficacy of the heat killing of Mycobacterium tuberculosis.

There is concern that current procedures for the heat inactivation of Mycobacterium tuberculosis may not be adequate. This raises serious safety issues for laboratory staff performing molecular investigations such as IS6110 restriction fragment length polymorphism typing. This paper confirms that the protocol of van Embden et al, as performed routinely in this laboratory, is safe and effective ...
