Almost 400 years after the (re)discovery of the lymphatic vascular system (LVS) by Gaspare Aselli (Asellius G. De lactibus, sive lacteis venis, quarto vasorum mesaraicorum genere, novo invento Gasparis Asellii Cremo. Dissertatio. (MDCXXIIX), Milan;
To determine the cardiovascular impact and whether reduced body temperature was responsible for the other effects, the researchers exposed conscious mice to normal air or 80 ppm hydrogen sulfide and 17.5% oxygen under different temperature conditions. As in the previous study, breathing the gas at ro...
4. Metham Sodium has been used for decades in sewer line root control and as a fungicide fumigant. It yields a poisonous and caustic gas which kills roots very effectively (100%) inside the pipe and outside the pipe where the gas travels. Its disadvantages are its effects on humans (it ...
Previous investigations into the effects of low-dose hydrogen sulfide showed that the gas could lower body temperature and metabolic rate and also improved survival of mice whose oxygen supply had been restricted. But since hypothermia itself cuts metabolic needs, it was unclear whether the reduced b...
A sewer system is a set of construction facilities used for the quick removal of wastewater from the humans’ immediate environment and its transport to a wastewater treatment plant or direct discharge into an appropriate recipient. In order for the sewer system to perform its purpose properly, ...
