Mechanism of Action NAC is a precursor to intracellular glutathione. It is a known nucleophile and free radical scavenger, either directly or as a source of cysteine and glutathione. In rodent models, NAC inhibits a variety of mutagen/carcinogen-induced cancer biomarkers, interferes with the promotion phase of multistage carcinogenesis, and produces a decrease in the incidence of carcinogen-induced tumors of the lung, colon, and bladder. This activity may be due to its ability to enhance glutathione S-transferases, glutathione peroxidase, glutathione reductase, and NADH- and NADPH-quinone reductase. In vitro and in animal models, NAC exhibits anti-invasive, antimetastatic, and antiangiogenic properties. In one study, NAC was found to inhibit the proliferation of androgen-independent human PC-3 prostate cancer cells through upregulation of Cyr61 protein expression. NAC can also be employed as a mucolytic agent in the treatment of respiratory diseases and as an antidote to acetaminophen poisoning. Animal studies report that NAC may also protect against doxorubicin toxicity and bladder cystitis induced by ifosfamide and cyclophosphamide.

I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
