Cigarette Smoking Impedes Tendon-to-Bone Healing
Orthopaedic surgery researchers at Washington University School of
Medicine in St. Louis have identified yet another reason not to smoke.
Studying rotator cuff injury in rats, the research team found exposure to
nicotine delays tendon-to-bone healing, suggesting this could cause
failure of rotator cuff repair following surgery in human patients.

Changing Length of Days Reverses How Estrogen Affects Aggressiveness in
Mice
New research shows how simply varying the length of daylight to which
mice are exposed to can change how aggressively they react to other mice.
The study found that in the short days of winter, the class of hormones
called estrogens acts to increase aggression in males of a particular type
of mouse. However, in the long days of summer, estrogen decreases
aggression among the male mice. (Embargo expired on 18-Oct-2006 at 13:00

Pleasure & Pain: Brain's Pleasure Chemical Responds to Pain, Too
For years, the brain chemical dopamine has been thought of as the
brain's "pleasure chemical", and studies have linked the addictive
properties of drugs like cocaine to their effects on the dopamine system.
But now, a new study adds a new twist to dopamine's fun-loving reputation:
pain.

Green veg compounds may protect against breast cancer
By Stephen Daniells
19/10/2006 - Compounds found in broccoli and other green vegetables could inhibit the growth of breast cancer cells, according to an in vitro study.
The cancer-fighting properties of broccoli, a member of the crucifer family of vegetables, are not new and previous studies have related these benefits to the high levels of active plant chemicals called glucosinolates. These are metabolised by the body into isothiocynates, and evidence suggests these are powerful anti-carcinogens. The main isothiocynate from broccoli is sulforaphane.
Other studies have proposed that the compound indole-3-carbinol (I3C), a phytochemical found naturally in cruciferous vegetables, could also have potential prevention activity against hormone-responsive tumours, such as breast, ovarian and prostate cancer.
New data, published on-line ahead of print in the journal Carcinogenesis (doi:10.1093/carcin/bgl171) and presented recently at the National Cancer Research Institute Conference, adds to these studies by reporting that I3C could alter receptors in breast cancer cells and induced apoptosis (programmed cell death).
The researchers also reported that the green vegetable compound may also make the tumour cells more susceptible to pharmaceutical approaches.
“It is notoriously hard to conduct large-scale studies looking at the cancer preventing effects of these substances in our food, but the in vitro evidence is growing that these agents would make an ideal addition to preventive and combinatorial anti-cancer strategies,” said lead researcher Professor Margaret Manson from the University of Leicester.
The scientists, funded by the Medical Research Council (MRC) looked at the impact of I3C on four different types of breast cancer cells (MDA-MB-468, MDA-MB-231, MCF7 and HBL100), and found that I3C-induced apoptosis in three of these cell types; MCF7, MDA-MB-468 and MDA-MB-231.
“Although we need to carry out further studies on tumours removed from patients, the potential benefits are clear,” said Professor Manson.
“Dietary agents are kind to normal cells at doses, which can slow down or kill cancer cells. Combining them with drugs may enhance the drugs' effectiveness and could allow reduced doses to be given to patients.
“As dietary substances like I3C have a proven track record of being safe for the patient, we hope that the journey to clinical trials will be relatively straightforward,” she said.
It was also suggested that the ‘dose' of I3C present in cruciferous vegetables may not be sufficient to be high enough to replicate the effects seen in vitro which may open up opportunities for high-dose I3C extracts from vegetables or breeding of “super” forms of the veggies with higher amounts of I3C, along similar lines to the broccoli developed by British researchers said to contain three times the levels of sulforaphane than normal mature broccoli.
Some broccoli-extracts are currently available on the market, such as Cyvex's Nutrition's BroccoPlus, combines six per cent glucosinolates with sulforaphane, delivering high doses of these compounds in powder form, and B&D Nutritional Ingredients' sgs-100, a broccoli seed extract from a plant strain that is reported to be unusually high in sulforaphane glucisinolate (SGS).
Dr. Sheila Bingham, director of the MRC Centre for Nutrition and Cancer at the University of Cambridge said: “This study supports the growing evidence that food can be important in altering our susceptibility to cancer and possibly survival from it, and may help explain why fruits and vegetables are so important.”
Josephine Querido, science information officer at Cancer Research UK, said: "This study adds to the evidence that I3C molecule - found in broccoli, cabbage and other cruciferous vegetables - can help block the growth of breast cancer cells.”
But Querido stressed that the work was done in a laboratory, and that it was too soon to tell if I3C could have a role to play in breast cancer prevention and/or treatment.
"After stopping smoking, a healthy balanced diet including plenty of fruit and vegetables is the best way to reduce your risk of developing certain cancers," she said.

Inner workings of a food-poisoning organism called Campylobacter lari have been uncovered in greater detail than ever before by Agricultural Research Service (ARS) scientists in California. Their forays into the genetic makeup, or genome, of this little-known pathogen reveal new details about the structure, or sequence, of its genes.
Research microbiologist William G. Miller of the agency's Produce Safety and Microbiology Research Unit led the investigation, working forward from a rough draft of the genome prepared earlier for ARS by The Institute for Genomic Research, Rockville, Md. Miller is based at the ARS Western Regional Research Center in Albany, Calif.
C. lari is a cousin of the better-known C. jejuni, another "bad-guy" bacterium. C. jejuni causes millions of cases of diarrhea every year, according to Miller. Food poisoning outbreaks occurring in some other countries have been attributed to C. lari and have attracted the attention of U.S. food safety researchers and public health professionals.
The new knowledge about the structure of C. lari genes could open the door to innovative strategies that snafu the microbe's ability to infect us.

What others are saying about Dave Ellis
and the Fueling Tactics sports nutrition system
Sports dietitian and strength coach Dave Ellis has been refining and field-testing his three-step Fueling Tactics®sports nutrition system for 25 years now and in the summer of ’06 released his nutrition system on DVD for the first time (see www.fuelingtactics.com - a one-hour version for athletes and a two-hour version for coaches and teachers).
Ellis directed nutrition services during the University of Nebraska’s three national championship football seasons in 1994, ’95 and ’97. And he was on board when the New England Patriots won their third Super Bowl capping off their 2004 season, but as you can see from the quotes below Dave’s practice now spans every aspect of sports:
“A well organized approach to educating and feeding athletes can make a difference, especially at the highest levels of sport. Dave’s Fueling Tactics system is a time-tested performer.”
--Head coach Bill Belichick, three-time Super Bowl champion New England Patriots
“We knew early in Dave's career that he could help us sell athletes on the value of nutrition. He has endless curiosity in this area. Dave was a big part of our three national championship teams.”
--U.S. Congressman Tom Osborne (Neb.); head football coach (1973-97) at the University of Nebraska
"When we were ready to evolve our nutrition and body composition services for basketball we brought in a professional in Dave Ellis. Dave's ability to work with all aspects of our organization was evident starting with the positive changes made in our travel meals. Being able to work with administration, sports medicine and strength and conditioning is key in making changes that really work and Dave has the experience to navigate them all."
--Lute Olson, Head Basketball Coach, University of Arizona
“It's great to see the evolution in Dave's nutrition system over the years. It's obvious that he keeps up with the research as well as the trends that top athletes and coaches are exposed to. Dave has become one of the true Professionals in his field."
--Barry Alvarez, Athletic Director & Former Football Coach, University of Wisconsin Athletics
“Dave Ellis is one of the few people that a head coach can put in front of the entire team with confidence that he’s going to deliver concise messages with credibility. Few people in sports have been behind the scenes of more organizations, and he’s learned something from all of them.”
--Bob Stoops, Head Football Coach, University of Oklahoma
“Dave has always been able to communicate complex nutrition concepts to athletes with the energy it takes to keep their attention. Dave is one of the few in the field with the credibility to influence athletes at every level of competition.”
--Jerry Schmidt, Head Strength Coach, University of Oklahoma
“I’ve witnessed from day one how Dave’s been blazing a trail in sports nutrition and strength training. He always seems to be ahead of the curve. He’s the only person I know who has a system to determine athletes’ weight-carrying capacity. Knowing the limitations of an athlete’s frame adds much needed objectivity in determining the position an athlete may be best suited to play.”
--Frank Solich, Head Football Coach, Ohio University
“Dave was one of the first to realize there could be diminishing returns when adding body weight to athletes, even if it was lean weight. As an orthopedic surgeon, that kind of insight, which came early in Dave's career, is characteristic of his overall success. Dave is an innovator!”
--Pat Clare, Head Orthopedic Surgeon, University of Nebraska Athletics Orthopedic Group
“As an N.B.A. strength coach it is very important to determine the optimal body weights of our players. The unique frames of NBA athletes make it particularly challenging but Dave has devised an objective method of determining frame size that looks at skeletal parameters beyond height. The end result is a customized, easy to use nutrition program that lays the foundation for optimized athletic performance."
--John Murray, Strength Coach, Golden State Warriors
“It's great to find someone who delivers a message that athletes can wrap their arms around. Dave presented data in a sex specific manner so that our female athletes related to it and were motivated by it. We saw immediate results because our athletes listened!”
--Sherri Coale, Head Women's Basketball Coach, University of Oklahoma
"Dave has the experience and credibility to have an immediate impact with athletes. However, his ability to connect with them in an organized and highly informative way is what has kept our athletes talking about his Fueling Tactics system long after his visit. He is an asset we plan to continue to use with our football team well into the future. As a matter of fact, we plan on sharing him with all our athletics teams at Boston College."
--Todd Rice, Head Strength Coach, Boston College
“Dave’s 3-step Fueling Tactics system helps athletes outwork the competition with the power of food! Fueling Tactics is a program we are introducing to our USA Hockey athletes in 2006.”
--Mark Tabrum, Director of Coaching Education, USA Hockey
"Dave is one of the few Sports Dietitians who can illustrate how professional athletes routinely gain muscle in a safe and ethical fashion. Young male and female athletes need to hear this message so they don't lose perspective on just how many athletes are doing it right.”
--Don Hooton, Founder of the Taylor Hooton Foundation (www.taylorhooton.org)
“Both my wife and I were immediately impressed with Dave's down-to-earth approach and motivational style. He has vast experience and stays on top of the latest research.”
--Mike Wahle, All Pro Offensive Lineman, Carolina Panthers
“Dave’s counsel and advice on nutrition and supplementation has been greatly valued by the Professional Baseball Strength & Conditioning Coaches Society.”
--Tim Maxey, Cleveland Indians Strength & Conditioning Coach
“If you’re looking for state of the art research and application in the areas of nutrition, metabolism, body composition and frame estimation, the leader in the field is clearly Dave Ellis.”
--Paul Golberg, MS, RD, CSCS, Strength & Conditioning/Dietitian, Colorado Avalanche Hockey Club
“As an N.B.A. strength coach it is very important to determine the optimal body weights of our players. The unique frames of NBA athletes make it particularly challenging but Dave has devised an objective method of determining frame size that looks at skeletal parameters beyond height. The end result is a customized, easy to use nutrition program that lays the foundation for optimized athletic performance. “
--John Murray, Strength Coach, Golden State Warriors
“In all my years of being around athletics I have never heard a nutrition message that is more grounded and easy to understand than Dave's. It's a message that is applicable to everyone, not just athletes. Americans in general need the wake-up call that Dave's Fueling Tactics system delivers.”
--Brian Boitano, Olympic Gold Medalist, Professional Figure Skater
"I send athletes and coaches to Dave to benefit from his extremely professional and effective Fueling Tactics system, and the results have been outstanding. For those whose schedules don't yet permit for them to consult with Dave personally, I provide them a copy of his DVD and poster, which is an easily understood, excellent educational tool. I highly recommend Fueling Tactics System as a key component to athletic success."
--Neil M. Cornrich, NC Sports, LLC
“Dave’s depth of knowledge and practical application of sports nutrition is at the world class level. He can go from cellular metabolism to “coaching” athletes about a food first approach in the same breath. That is what makes Dave an invaluable resource to the athletic community.”
--Michael Barnes, National Strength & Conditioning Association, Director of Education
“A lot of people talk about sports nutrition, but few practice it on a full time basis. Even fewer have done it for 25 years! Dave is the real deal and has been doing it longer than anyone in the business."
--Rob Skinner, Director of Sports Nutrition, Georgia Tech Athletics
“I don't know of any other sports dietitian who practices at the competitive level of sports that Dave does. He has the practical expertise that can actually help us determine what direction we need to take some of our clinical research. Dave often knows what works long before we have the data to validate it. If Dave says it works for his athletes, you can bet he has first hand knowledge."
--Wayne Askew, PhD, Professor and Director, Division of Nutrition, College of Health, University of Utah
“Few people outside the highest levels of sport get to witness Dave behind the scenes. Having seen his practice evolve over the years, and having tracked his successes, it’s clear to me that his methods have become highly refined, and that he offers one-of-a-kind expertise that you simply won’t find anywhere else."
--Mitchell Kanter, Director of Nutrition, Cargill Inc.
"Dave's 25+ years in the sports nutrition world are unsurpassed; I don't know anybody in the sports nutrition world who is better connected or grounded on the realities of feeding athletes than Dave Ellis. You can always get a realistic perspective on what works with Dave which has made him a valuable advisor with my practice as a Sports Dietitian."
--Christopher R. Mohr, PhD, RD, Ownder www.MohrResults.com
“Dave is light years ahead of anyone in sports nutrition. His Fueling tactics are a unique blend of cutting edge nutritional science and 25 years of personal experimentation with feeding athletes. His basic and applied knowledge on nutrition, metabolism, and performance is unmatched – Dave is the total package when it comes to optimally feeding athletes.”
--Jeff S. Volek, PhD, RD Nutrition and Exercise Researcher, University of Connecticut
"We have gotten a great deal of mileage out of Dave's Advanced Fueling Tactics DVD as a class room educational tool or just by playing it in areas where the athletes congregate. It's a message they need to hear over and over. The ability to send a copy of the Fundamental Fueling Tactics DVD home to educate those cooking for the athletes is also key in closing the circle.”
--Zach Duval, General Manager, Explosive Edge Training, Omaha NE
