naturalist_0616 UNLOCK YOUR PINEAL GLAND..... Lol. #bullshit
~~~~~~~~~~~~~~~~~~~~~~~~~ EPA's drinking water standard differs from HHS' recommended optimal fluoridation level because the two benchmarks have different purposes and are set under different authorities.
The EPA's enforceable standard for the highest level of fluoride that is allowed in public water supplies is 4.0 milligrams per liter, and is set to protect against risks from exposure to too much fluoride. The HHS proposed recommended optimal level of 0.7 milligrams per liter is set to promote public health benefits of fluoride for preventing tooth decay while minimizing the chance for dental fluorosis.
luoride works in two main ways: by slowing the activity of bacteria that cause decay, and by combining with the enamel on the surface of the teeth to make it stronger and more resistant to decay. Fluoride in the water, although at a lower concentration than in toothpaste, maintains a constant low level of fluoride in the dental plaque and saliva all day. Toothpaste provides a high level of fluoride, but only for 1-2 hours after brushing, so the water exposure during the remainder of the day takes over after that.

Pineal gland

The pineal gland or epiphysis synthesizes and secretes melatonin, a structurally simple hormone that communicates information about environmental lighting to various parts of the body. Ultimately, melatonin has the ability to entrain biological rhythms and has important effects on reproductive function of many animals. The light-transducing ability of the pineal gland has led some to call the pineal the "third eye". Light exposure to the retina is first relayed to the suprachiasmatic nucleus of the hypothalamus, an area of the brain well known to coordinate biological clock signals. Fibers from the hypothalamus descend to the spinal cord and ultimately project to the superior cervical ganglia, from which post-ganglionic neurons ascend back to the pineal gland. Thus, the pineal is similar to the adrenal medulla in the sense that it transduces signals from the sympathetic nervous system into a hormonal signal.

  •   naturalist_0616 HARVARD STUDY IQ FLUORIDE IMPLICATION? ---->FALSE! This is a statement that has been taken out of context to support their claim. The Harvard ‘Study’ was not a study, but rather a meta-analysis (crunching of numbers from other studies). It used statistics from studies done in China to look at children’s IQs from areas that contained high levels of fluoride versus low levels of fluoride. The ‘high’ fluoride areas were areas known to have ten times or more the concentration of optimally fluoridated water. Optimally fluoridated is what we have had in Pinellas County for the last 9 years and currently fighting to re-establish. Optimallevels means establishing the right balance of enough fluoride in the water to maximize the benefits of tooth decay prevention, while minimizing potential to contribute to dental fluorosis. The optimal level of fluoride is 0.7ppm. Just like medications used to treat diabetes or cancer, the right amount controls a disease and too much can have harmful effects. You have to exhibit common sense.

    In addition, two of the scientists who compiled the numbers for the Harvard Study, stated that “it does not address the safety of fluoridation levels typical of American drinking water. These results do not allow us to make any judgment regarding possible levels of risk at levels of exposure typical for water fluoridation in the U.S.” In one of the Chinese studies, the researchers even stated that ‘The IQ of adults in the area were also measured and the intellectual ability and even life expectancy of people in the (high-fluoride) endemic region appeared to be higher than the (low-fluoride) non-endemic region, indicating that the effect of fluoride poisoning on intellectual ability is negligible.’ 3min

naturalist_0616 Immune responses are tightly regulated via signaling through numerous co-stimulatory and co-inhibitory molecules. Exploitation of these immune checkpoint pathways is one of the mechanisms by which tumors evade and/or escape the immune system. A growing understanding of the biology of immune checkpoints and tumor immunology has led to the development of monoclonal antibodies designed to target co-stimulatory and co-inhibitory molecules in order to re-engage the immune system and restore antitumor immune responses. ~~~~~~~~~~~~~~~~~~~~
Anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibodies were among the first to be tested in the clinic, and ipilimumab was the first immune checkpoint inhibitor approved for an anticancer indication. Agents targeting the programmed death 1 (PD-1) pathway, either PD-1 or one of its ligands, programmed death ligand 1, are in active clinical development for numerous cancers, including advanced melanoma and lung cancer. Understanding the different mechanisms of action, safety profiles, and response patterns associated with inhibition of the CTLA-4 and PD-1 pathways may improve patient management as these therapies are moved in to the clinical practice setting and may also provide a rationale for combination therapy with different inhibitors. Additional immune checkpoint molecules with therapeutic potential, including lymphocyte activation gene-3 and glucocorticoid-induced tumor necrosis factor receptor-related gene, also have inhibitors in early stages of clinical development. Clinical responses and safety data reported to date on immune checkpoint inhibitors suggest these agents may have the potential to markedly improve outcomes for patients with cancer.
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The immune system depends on multiple checkpoints or “immunological brakes” to avoid overactivation of the immune system on healthy cells.15-16 Tumor cells often take advantage of these checkpoints to escape detection by the immune system.
Inhibiting a checkpoint (ie, “releasing the brakes”) on the immune system may enhance the anti-tumor T-cell response. This class of therapy has shown efficacy in cancer and clinical trials are ongoing.
