– Melatonin has been described to possess cell protecting activity in normal cells but was shown to induce apoptotic cell death in cancer cells. It potentiates apoptosis induced by the flavonoid flavone significantly. A combination of flavone and melatonin increased caspase-3-like activity 30-fold and 80% of cells exhibited fragmentation of DNA when compared to untreated controls. Melatonin caused an increase in cytosolic lactate levels that most likely allows the flavone-induced activation of the mitochondrial pyruvate/lactate importer to deliver more substrates to mitochondrial respiration.
Melatonin Enhances the Anti-Tumor Effect of Fisetin
– Melatonin is a hormone identified in plants and pineal glands of mammals and possesses diverse physiological functions. Fisetin is a bio-flavonoid widely found in plants and exerts antitumor activity in several types of human cancers. However, the combinational effect of melatonin and fisetin on antitumor activity, especially in melanoma treatment, remains unclear. Here, we tested the hypothesis that melatonin could enhance the antitumor activity of fisetin in melanoma cells and identified the underlying molecular mechanisms. The combinational treatment of melanoma cells with fisetin and melatonin significantly enhanced the inhibitions of cell viability, cell migration and clone formation, and the induction of apoptosis when compared with the treatment of fisetin alone. Moreover, such enhancement of antitumor effect by melatonin was found to be mediated through the modulation of the multiply signaling pathways in melanoma cells.

The Flavonoids Hesperidin and Rutin Promote Neural Crest Cell Survival
Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm germ layer, and in turn give rise to a diverse cell lineage—including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurons and glia.
The Flavonoids Hesperidin and Rutin Promote Neural Crest Cell Survival
The neural crest (NC) corresponds to a collection of multipotent and oligopotent progenitors endowed with both neural and mesenchymal potentials. The derivatives of the NC at trunk level include neurons and glial cells of the peripheral nervous system in addition to melanocytes, smooth muscle cells and some endocrine cells. Environmental factors control the fate decisions of NC cells. Despite the well-known influence of flavonoids on the central nervous system, the issue of whether they also influence NC cells has not been yet addressed. Flavonoids are polyphenolic compounds that are integral components of the human diet.
The biological activities of these compounds cover a very broad spectrum, from anticancer and antibacterial activities to inhibition of bone reabsorption and modulation of inflammatory response. In the present work, we have investigated the actions of the flavonoids hesperidin, rutin and quercetin on NC cells of quail, in vitro. We show for the first time, that hesperidin and rutin increase the viability of trunk NC cells in culture, without affecting cell differentiation and proliferation. The molecular mechanism of this action is dependent on ERK2 and PI3K pathways. Quercetin had no effect on NC progenitors. Taken together, these results suggest that flavonoids hesperidin and rutin increase NC cell survival, which may be useful against the toxicity of some chemicals during embryonic development.
Zzz Best Sleep EVER
Where do you place sleep in your life? For me I have learned to place it at the top of the pile of important things to do. A little over a year ago I really started focussing on sleep as thee most important 8-9 hours of my day. Everything else took a back seat. Boy what a trip it has been. Here’s a few things I’ve observed.
Sleep has 2 shifts or phases. Without fail I always wake up about 1/2 way through my full nights sleep. It’s not always a full 8 hours but I do allow for up to 9 hours and 36 minutes. I usually get up and use the restroom for good measure, make sure I drink a good amount of water and take my systemic enzymes. Always falling back to sleep immediately.
1:36 before sunrise. Through additional research I discovered some who believe that there is what is called a/the creators hour that starts 1 hour and 36 minutes before sunrise. I don’t personally know of any science behind it, but I have noticed that I am much more creative at that time in the morning and flow state is much easier to achieve at that time.
Bedtime…9:36 before sunrise. What I decided to do is put myself in bed at about this time every night. I’m not very precise because it is an ever moving target by about 6 minutes per day. This has been absolute magic for quality of sleep and it always provides for a solid 8 hours of darkness for sleep.
Sun down; fork down. If it were always possible I would only ever eat during daylight hours. When the sun goes down so does my fork, knife and spoon. This allows for your food to clear the stomach before bedtime. It will also allow for supplements you need to take on an empty stomach before bed.
Sleeping on the job. That is our job. On the other hand we have a whole legion of microbial life living in and on our body that have work to do. And they tend towards nocturnal behavior. In other words, they work the night shift. In contrast the human part of us tends toward life under the sun. All those other living things that make up our existence and wellbeing work while we sleep.
Shift work. It would seem that our best work as a human and legion of microbial life is done in shifts. And that when we observe this obediently our overall health and wealth in life is filled to the top and overflowing. Yup, that human aspect of us has a responsibility to the other 99% of the DNA on this body to simply get out of their way and let them to their job, on their shift.
A cocktail for the ageless. As a benefit our night shift, or microbial partners graciously provide us with a bio-chemical cocktail that helps us fall asleep quickly. It’s hard not to notice if you are observant. For years I just blew past all the signs while looking for my second wind. All the while ignoring my bodies cue’s. My feeling is that this is our body’s window for falling asleep that we have ignored since modern electric and artificial lighting. And that once we blow past that bio-chemical cocktails effects our ability to fall asleep is diminished. I’ve come to appreciate it and almost enjoy it.
These are just some of what I have observed I look forward to learning more over the years. I’ve found that my body repairs and heals at a much more advanced rate when I play by these rules. Once I started seeing the benefits of simply sleeping smarter it became much more difficult to find good reasons to stay awake much later than 8 or 9. I am personally convinced that there is magic to be found in a perfected sleep.

Pellagra: Interesting Alert-NIH
WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Despite the treatable dementia and psychosis, pellagra is often under-diagnosed, especially in developed countries and alcoholic patients. Pellagra should be routinely suspected in alcoholic patients because the response to appropriate treatment is typically dramatic.
Alcoholic Pellagra as a Cause of Altered Mental Status in the Emergency Department ~ Source-NIH
BACKGROUND:
Pellagra, which is caused by a deficiency of niacin and tryptophan, the precursor of niacin, is a rare disease in developed countries where alcoholism is a major risk factor due to malnutrition and lack of B vitamins. Although pellagra involves treatable dementia and psychosis, it is often underdiagnosed, especially in developed countries.
CASE REPORT:
In Japan, a 37-year-old man presented to the emergency department with altered mental status and seizures. Wernicke encephalopathy and alcohol withdrawal were suspected. The patient was treated with multivitamins, which did not include nicotinic acid amide, and oral diazepam. Despite medical treatment, his cognitive impairment progressively worsened, and eventually, pellagra was suspected. His response to treatment with nicotinic acid amide was substantial, and he was discharged without any long-term sequelae. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Despite the treatable dementia and psychosis, pellagra is often underdiagnosed, especially in developed countries and alcoholic patients. Pellagra should be routinely suspected in alcoholic patients because the response to appropriate treatment is typically dramatic.
Respectin the Pectin
Respecting the pectin. Such a wonderfully powerful health resource.
Abstract
A simple procedure for determining the galacturonic acid and methanol contents of soluble and insoluble pectins, relying on enzymatic pectin hydrolysis and colorimetric quantification, is described. Pectin samples are incubated with a commercial pectinase preparation, Viscozyme, then the galacturonic acid content of the hydrolyzed pectin is quantified colorimetrically using a modification of the Cu reduction procedure originally described by Avigad and Milner. This modification, substituting the commonly used Folin-Ciocalteau reagent for the arsenic containing Nelson reagent, gives a response that is linear, sensitive, and selective for uronic acids over neutral sugars. This method also avoids the use of concentrated acids needed for the commonly used m-phenylphenol method. Methanol, released by the action of the pectin methylesterase found in the Viscozyme, is quantified using alcohol oxidase and Purpald. This combined enzymatic and colorimetric procedure correctly determined the galacturonic acid and methanol content of purified, soluble citrus pectin. Application of the procedure to water insoluble pectins was evaluated with water insoluble material from apples and oranges. In both cases good agreement was obtained between this method and commonly used methods based on chemical pectin hydrolysis. Good agreement between these procedures was also found in the analysis of both soluble and insoluble pectins from several tomato products.
Glucuronic Acid, a Precursor of Ascorbic Acid in Aspergillus niger
Galacturonic acid prepared from pectin can be used to synthesize vitamin C.
Chemical Formula: C6H10O7
Layman’s explanation: Galacturonic acid is the monobasic acid resulting from oxidation of the primary alcohol group of D-galactose to carboxyl. It is widely distributed as a constituent of pectins (compounds with heterogeneous grouping of acidic structural polysaccharides, found in fruit and vegetables), many plant gums, and mucilages (gummy substances obtained from certain plants, which are used as food stabilizers). Gums tend to be used as thickening and bulking agents in pharmaceutics, and they play a less obvious part in most plants. Once swallowed, their actions are no different from those of the mucilages. D-Galacturonic acid prepared from pectin can be used to synthesize vitamin C. Native pectin is a mixture of polysaccharides, with the major component a polymer of -D-galacturonic acid. Pectin has numerous other medical and pharmaceutical uses, for example in combination with plant hemicelluloses and lignin, may be useful dietary constituents in preventing coronary heart disease, diverticular disease, ulcerative colitis, and a variety of other Western diseases.
