What His Patients Say:
"Dr. Enepekides is the most caring and considerate doctor I have ever encountered. He saved my life by performing surgery for my thyroid cancer. He was very thorough and very kind in explaining what was happening to me and the next steps. Although he performed two surgeries within four months' time in the same neckline, the scar is non-existent. I will miss seeing him."
"Dr. Enepekides is an outstanding surgeon. He operated on my husband who had a tumor in his parotid gland. He spent a lot of time explaining the complicated surgery. He was honest but very caring and kind. We knew of his great credentials but were thrilled with his bedside manners. He even took into consideration my husband's line of work when doing the nerve, muscle, and skin grafts! I believe God put us with the best."
Welcome, Dr. Enepekides!
Wine and Cancer Prevention:
Truth or Fiction?
Lattice Biologics separates the scientific truth of wine's wellness wonders from wishful thinking
You might have heard that wine is good for the heart or that it can help prevent cancer (not to mention a variety of mental and emotional meltdowns!). As much as those of us who enjoy the beverage hope that's the case, can we count on it?
The big player in the chemistry of wine and wellness is resveratrol.
Resveratrol is a polyphenolic (
micronutrient, with evidence linking it to the prevention of degenerative diseases such as cancer and cardiovascular diseases)
compound naturally found in grapes, red wine, grape juice, peanuts, cocoa, and berries of Vaccinum species (blueberries, bilberries, and cranberries).
To get to the bottom of the glass, we turned to The Linus Pauling Institute (named for the famed activist, scientist, and "founding father of molecular biology") Micronutrient Information Center. They have the following to say about this potentially potent polyphenolic compound:
Biological activities related to cancer prevention:
Inhibition of proliferation and induction of apoptosis: Following
damage, the cell cycle can be transiently arrested to allow for DNA repair or activation of pathways leading to cell death (
) if the damage is irreparable... Resveratrol has been found to induce cell cycle arrest and/or apoptosis (programmed cell death) in a number of cancer cell lines.
Inhibition of tumor invasion and angiogenesis:
cells invade normal tissue aided by
. Resveratrol has been found to inhibit the activity of at least one type of matrix metalloproteinase. To fuel their rapid growth, invasive tumors must also develop new blood vessels by a process known as
. Resveratrol has been found to inhibit angiogenesis
. (There was no position regarding "in vino.")

THIS ISSUE'S FUN FACT: Beyond Fermentation - Savor the Wine Science
METABOLOMICS - WINEMAKERS RELY ON HIGH-TECH TESTING FOR PERFECTION
Due to an increased understanding of vino-chemistry, the age-old process of winemaking has made a sharp departure from the its original art form to embrace modern science.
Makers today recognize that wine "contains hundreds of volatile and non-volatile compounds that influence its flavor." Most of these chemicals are not even present in the starting ingredients, but develop throughout the fermentation and aging process.
In order to harness wine's flavor potential, wine-makers have begun to adopt
analytical chemistry and biochemistry technologies for their work.
These include: mass spectrometry (MS) and nuclear magnetic resonance (NMR) which are used to identify the complexities of wine's chemical components which impart each particular flavor.
Metabolomics is "the study of the total chemical composition of biological materials."
Tools for Wine Metabolomics: gas chromatography-coupled mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and NMR.
Each metabolomics method detects just a small portion of the metabolome-volatiles present so researchers must often combine some or all methods to achieve the most comprehensive understanding of the profiles.

OR NOT TO PEPPER?
My favorite way to order a glass of wine at dinner is to ask the restaurant to recommend their most "peppery" red. If you're like me, it's all about that spicy little kick. But there's surprising science behind the reason some people never request a glass of the peppery stuff.
Upon extensive investigation into the chemicals that give some Australian Shiraz wines their characteristic black pepper aroma, Markus Herderich and his team at the Australian Wine Research Institute ultimately identified a particular sesquiterpene (a class of terpenes, which are a type of plant-based organic compound) called rotundone as responsible for the signature flavor.
They also discovered that while the majority of their panelists could detect rotundone in "as little as 8 ng/L in water," 20% of them couldn't identify it even at a 500 times greater concentration. The big surprise is that almost a quarter of all people are nearly anosmic for rotundone, meaning they lack the ability to smell it at all. This could be part of the reason why two people can sample the same wine and have completely different interpretations of its taste.
As it turns out, taste in wine is not just personal, it's biological.
RUINED WINE'S PHANTOM STINK
Have you ever opened a beautiful, old bottle of wine with great anticipation - only to be met with an awful, dank basement, mildew stench upon popping the cork?
That unpleasant odor scent tells you the bottle has succumbed to the much maligned "cork taint." The chemical at fault for the ruined bottle of wine, 2,4,6-Trichloroanisole (TCA), "occurs when natural cork fungus inadvertently contacts chlorine cleaning products during wine bottling." But, unlike other foul-smelling chemicals, TCA knocks out the nose's scent receptors instead of engaging them. So, while it seems like you're smelling something terrible, your nose is actually being "numbed."
But that doesn't make much "scents." (get it?) Osaka University's Hiroko Takeuchi and colleagues determined that TCA knocks out our olfactory receptors' electrical signals, rather than stimulate them. So, what you think you are "smelling" when you experience cork taint is really just a sense of numbness of your scent receptors.
While researchers are still unclear as to why the compound that numbs our sense of smell also simultaneously gives us the impression of smelling something foul and musty, they do conclude that the reduction of activity in scent-sensing cells "may induce some kind of pseudoolfactory sensation" or "phantom smell."
The good news for most of us is that modern day winemakers are aware of TCA and have removed chlorine cleaning products from their bottling process, which means that the nasal assault of cork taint will only be a potential problem for those with their hands on older vintages. And we don't feel too sorry for those folks, anyway!
WINE & WELLNESS cont. THE RESEARCH
"Although resveratrol can inhibit the growth of cancer cells in culture and in some animal models, it is not known whether resveratrol can prevent and/or help treat cancer in humans.
The presence of resveratrol in red wine was initially thought to be responsible for red wine's beneficial cardiovascular effects. Two randomized, placebo-controlled trials reported that one-year consumption of a grape supplement containing 8 mg/day of resveratrol improved inflammatory and atherogenic status in subjects at risk for cardiovascular disease, as well as in patients with established coronary heart disease."
THE GOOD NEWS
THE BAD NEW
"Resveratrol administration has increased the lifespans of yeast, worms, fruit flies, fish, and mice fed a high-calorie diet, but it is not known whether resveratrol will have similar effects in humans."
(This might explain some of the reason fruit flies - the nasty bane of summertime wine drinkers everywhere - are so insistent at dive bombing my cabernet...)
"Experimental animal studies have suggested that resveratrol might be neuroprotective and be beneficial in the prevention and/or treatment of neurodegenerative diseases; however, clinical trials in healthy or cognitively impaired older people are currently very limited."
(This seems like important research. Are there any volunteers out there interested in furthering this data??)
THE BOTTOM LINE:
W IS FOR "WHY NOT?"
While the research is far from conclusive, that glimmer of hope is a good enough reason for us to savor a little fine wine with friends whenever we get the chance. Until the next time, we raise a glass to YOU!
