Ribose Improves Ventilatory Efficiency in Congestive Heart Failure Patients

Ventilatory efficiency is recognized as an important predictor of survival and disease progression among patients with congestive heart failure (CHF). Thus, improving ventilatory efficiency in this population is of prime importance. A research report suggests that D-Ribose can play a significant role in this key pursuit.

It is well accepted that failing hearts are energy starved and lack sufficient energy for normal function. D-Ribose, a naturally occurring monosaccharide, has been shown to play a vital role in cellular energy creation.

Mark A. Munger, PharmD, Professor of Pharmacotherapy summarized the study "Beyond the previously known benefits of ribose in enhancing myocardial energy levels and improving diastolic function parameters following ischemia, this study demonstrated a benefit in ventilatory efficiency, one of the most powerful predictors of survival in congestive heart failure patients."

L-Carnitine Inhibits Gestational Diabetes

Intake of L-carnitine L-tartrate during pregnancy may thwart a sequence of reactions leading to gestational diabetes, according to a study published in Chemical Monthly.

Scientists at the University of Vienna noted deficiency of carnitine in pregnant women from the 12th week of gestation through delivery leads to down-regulation of expression of certain enzymes involved in fatty acid metabolism; low mRNA levels of these enzymes promotes an increase in free fatty acid levels conducive to insulin resistance. The researchers found supplementation with L-carnitine L-tartrate (as L-Carnipure®, from Lonza) increased relative mRNA levels of these enzymes in pregnant women.

Low CoQ10 Levels Associated with 790% Increased Risk of Melanoma Metastasis

117 consecutive melanoma patients were enrolled in this study. Plasma coenzyme Q10 (CoQ10) levels were measured upon enrollment.

Researchers found that CoQ10 levels were significantly lower in melanoma patients than in control subjects. Further, it was noted that for melanoma patients with CoQ10 blood levels of less than 0.6 mg per liter, risk of developing metastatic disease increased by 790 percent, compared to those melanoma patients with blood levels of 0.6 mg per liter or higher. In addition, melanoma patients with higher blood levels were noted to have a metastasis-free interval that was almost double compared to patients with lower levels.

Berries Inhibit Oxidative and DNA Damage

Blackcurrants are small, juicy, dark purple berries that are high in vitamin C and have a slightly bitter taste. Boysenberries are genetically similar to blackcurrants. Both berry types are rich in anthocyanins, potent disease-fighting antioxidants. Fruits high in anthocyanins tend to have deep red or purple hues.

In a recent study, researchers discovered that both blackcurrant and boysenberry extracts helped combat oxidative stress and DNA damage, two processes that contribute to Alzheimer's disease, cancer, and aging. Although the study results are preliminary and need to be confirmed with further research, antioxidant-rich fruits remain a smart food choice. Eat a colorful assortment of different fruits and vegetables to get a healthy mix of disease-fighting compounds every day.

DHEA(S) Supplementation Reduces Age-Related Left Ventricular Stiffness and Fibrosis

The adrenal steroid hormone dehydroepiandrosterone (DHEA) and its sulfated derivative [DHEA(S)] have been extensively studied for their potential anti-aging effects. Researchers at the University of Arizona wrote, "Associated with aging, DHEA levels decline in humans, whereas other adrenal hormones remain unchanged, suggesting that DHEA may be important in the aging process.

Treatment with DHEA(S) decreased left ventricular stiffness in older mice and increased left ventricular stiffness in young mice.

The researchers concluded "exogenous DHEA(S) supplementation is capable of reversing the left ventricular stiffness and fibrosis that accompanies aging, with a paradoxical increased ventricular stiffness in young mice."

Melatonin Decreases Progression of Age-Related Macular Degeneration

Researchers investigated the effect of melatonin on age-related macular degeneration (ARMD). They decided to undertake the study because melatonin has been shown to control eye pigmentation and thereby regulate the amount of light reaching the photoreceptors. In addition, melatonin scavenges free radicals and protects retinal pigment epithelium cells from oxidative damage. Consequently, the age-related decrease in melatonin could be an important factor in the dysfunction in retinal pigment epithelium cells known to cause the initiation of ARMD.

“We conclude that the daily use of 3 mg melatonin seems to protect the retina and to delay macular degeneration,” the study authors wrote.

Vitamin E Helps Prevent Cataracts

A new study has found yet another reason for people to start supplementing vitamin E in their diet: to help prevent cataracts. As the most common cause of blindness worldwide, cataracts increase with age from less than five percent in persons under 65 to approximately half of those 75 years of age and older. Cataracts refer to lens cloudiness that gradually interferes with vision and leads gradually to a loss of vision.

Despite not examining vitamin E amounts, the researchers concluded that “long-term use of vitamin E supplements and higher riboflavin and/or thiamin intake may reduce the progression of age-related lens opacification.”

Resveratrol Reduces Flu Mortality by 60%

An Italian study found red wine is not only heart healthy, but may help fight flu as well. Scientists from Italy's Higher Health Institute, Rome University and the National Research Council discovered that resveratrol a compound in red wine that stops the flu virus from mutating.

"This discovery is very important because it increases the possibility of combating the virus and has proved effective against all different types of flu," the investigators said. "That resveratrol acts by inhibiting a cellular, rather than a viral, function suggests that it could be a particularly valuable anti-influenza drug."

Lycopene Reduces Blood Pressure

Clinical research conducted at Ben-Gurion University, Israel shows that lycopene complex, a tomato extract, reduces blood pressure in patients with mild to moderate hypertension.

In a random double-blind, placebo-controlled crossover trial, Dr. Esther Paran, M.D., evaluated the effect of tomato extract on blood pressure, endothelial function and plasma lycopene levels in grade I hypertensive patients.

“Eating a diet rich in tomato products and other antioxidant-containing fruits and vegetables is certainly a smart move,” said Dr. Paran, “But, a person would need to consume about five tomatoes to get the nutrients in one tomato extract capsule.”

Green Tea Associated with Reduced Cognitive Impairment

The objective was to examine the association between green tea consumption and cognitive function in humans.

High consumption of green tea at two or more cups per day by the top one-third of participants was associated with less than half the incidence of cognitive impairment, including severe cognitive impairment, than that found among participants whose intake was in lowest third at three or fewer cups per week. Participants whose tea consumption was in the middle third with a 1 cup per day habit, experienced a 38 percent reduction. No significant relationship between black tea or coffee consumption and cognitive impairment was observed.

The authors suggest that the lower prevalence of dementia and Alzheimer's disease in Japan could be explained by the green tea consumed by this population.

Selenium, Carotenoids Lower Mortality in Older Women

Intake of selenium and carotenoids such as lutein, zeaxanthin, lycopene and beta carotene may thwart inflammation-driven diseases leading to fatality in the aged.

Researchers followed elderly women enrolled in the Women's Health and Aging Studies I and II. Of those women followed, 14.1 percent died. The five major causes of death were heart disease (32.6 percent), cancer (18.0 percent), stroke (9.0 percent), infection (6.7 percent), and chronic obstructive pulmonary disease (5.6 percent).

The researchers discovered higher blood levels of selenium and total carotenoids were associated with a lower risk of mortality, and concluded higher levels of these compounds may lower risk of mortality.

Red Wine Consumption Reduces Inflammation

Adding Sicilian red wine to the diet of 48 non-drinkers for four weeks decreased levels of inflammatory and oxidative-stress-related biomarkers, and increased plasma antioxidant levels.

At the end of the red wine intake period, the researchers found significantly decreased levels of C-reactive protein, oxidized low-density lipoprotein (LDL) cholesterol and fibrinogen, as well as a lower LDL/high-density lipoprotein (HDL) ratio. In addition, red wine consumption increased total plasma antioxidant capacity and total HDL levels, suggesting moderate consumption of red wine in adults is a positive component of the Mediterranean diet.

Omega-3 fatty acids reduce risk of dry eye syndrome; Omega-6 fatty acids increase risk

In a study from Harvard Medical School in Boston, Massachusetts, and Brigham and Women's Hospital, women with a higher dietary intake of omega-3 fatty acids were at decreased risk of developing dry eye syndrome (DES).
Women who ate the most Omega-3 fatty acids lowered their chances of dry eye syndrome by as much as 68 percent. Conversely, those who ate a higher ratio of omega-6 fats versus omega-3 fats doubled their odds of dry eye syndrome. Although this is the first study that has evaluated this relationship, and confirmation from other studies is needed, the findings are consistent with clinical observations and postulated biological mechanisms," the authors write.

Resveratrol Protects Against Breast Cancer

Researchers report in the International Journal of Cancer that resveratrol, a component of red wine, inhibited the development of mammary tumors in mice and reduced the mean number and size of tumors in the animals. Past studies have indicated that resveratrol may possess anti-cancer activity on the basis of its in vitro effects on tumor cells and its effects in vivo on rodents transplanted with tumors or treated with carcinogens.

In the current study, the Italian researchers investigated resveratrol’s effects on the development of mammary tumors appearing in an experimental model of mice and breast cancer. Resveratrol supplementation delayed the development of spontaneous mammary tumors, reduced the mean number and size of mammary tumors and diminished the number of lung metastases in the mice.

Cranberry Compounds Block Cancer

New data shows that proanthocyanidins, or PACs, found in cranberries inhibit the growth of lung tumors and colon and leukemia cells. "While previous studies have shown that cranberry extracts inhibit the proliferation of cancer cells, this is the first study to confirm that it's the cranberry PACs that are the active components," said Catherine C. Neto, Ph.D.
"In light of our findings and previously published studies, cranberries may inhibit the spread of cancer in a variety of ways," said Neto.

Lower Colon Cancer Risk for Women with High Magnesium Intake

Drs Aaron R Folson and Ching-Ping Hong at the University of Minnesota in Minneapolis have confirmed an association between diets that contain higher amounts of magnesium and a reduced risk of colon cancer among women.

Foods high in magnesium such as vegetables and grains have already been shown to be protective against colorectal cancer because of their fiber content and beneficial micronutrients. Magnesium assists in calcium absorption and calcium has shown to be protective against colon cancer in other studies. Therefore, it was not clear after this 15-year study whether magnesium alone or other aspects of a healthy diet are responsible for the effects revealed in this study.

Stevia Suppresses Inflammation

Stevioside, a non-caloric sweetener isolated from Stevia rebaudiana Bertoni, may suppress harmful inflammation, according to a study published in the February 2006 Journal of Agricultural and Food Chemistry.

Researchers from Mahidol University in Bangkok, Thailand induced inflammation in a human leukemia cell line and treated the cells with stevioside. At 1 mM, stevioside significantly inhibited LPS-induced release of the inflammatory cytokines tumor necrosis factor alpha and interleukin 1-beta without exerting any direct toxic effects. The researchers concluded the data suggest stevioside attenuates synthesis of inflammatory mediators in LPS-stimulated THP-1 cells.

Omega-6 Fatty Acids Fuel Prostate Cancer Growth

A study published in the February 1 2006 issue of the journal Cancer Research reported that the addition of an omega-6 fatty acid to cultured prostate cancer cells doubled their growth rate compared to untreated prostate cancer cells. Omega-6 fatty acids are found in vegetable oils, such as corn and safflower oil, margarine, salad dressings, and prepared foods such as baked and frozen goods.

"After we added omega-6 fatty acids to the growth medium in the dish, we observed that tumors grew twice as fast as those without omega-6," Dr Fulford-Hughes explained. "Investigating the reasons for this rapid growth, we discovered that the omega-6 was turning on a dozen inflammatory genes that are known to be important in cancer."

Copper Deficiency Associated with Alzheimer's Disease

In this study, investigators looked into the ability of copper to stabilize cognitive decline in patients suffering from Alzheimer's disease.

Over 87% of the subjects exhibited a negative correlation between plasma copper levels and cognitive decline. Those with medium plasma copper levels made fewer mistakes in the memory test compared to those with low plasma copper levels. Researchers claim this finding supports the hypothesis of a mild copper deficiency in most Alzheimer patients. As such, they believe supplementation with copper might be necessary to stave off cognitive decline in Alzheimer's patients.
