Microchip Implants May Help Restore Lost Vision

Scientists at MIT and other research organizations are testing chip technologies that could help bring eyesight to individuals with conditions like age-related macular degeneration and retinitis pigmentosa.

Microchips place onto or inside the eyeball are assisted by a pair of electronic glasses the patient wears. Results vary, but many subjects report significant improvement in orientation and mobility. MIT hopes to have a device within two years so that they can get FDA approval from for use on chronic patients.

Avocados for Eye Health

Avocado for the eyes

Avocados contain a wide range of phytonutrients, which are thought to help prevent many chronic diseases, and are excellent for the eye health. Nutrients include trans neoxanthin, neochrome, lutein-5, 6-epoxide and chrysanthemaxanthin. The scientists also confirmed the presence of lutein, zeaxanthin, b-cryptoxanthin, a-carotene and b-carotene (all nutrients that support retinal health).

Since most of the nutrients are located near the skin of the fruit, you get most nutrients out of an avocado by peeling the fruit before slicing it.

Preterm Births Can be Drastically Reduced by Optimizing Vitamin D Levels

As preterm births are on the rise worldwide, there is powerful new evidence supporting the claim that sufficient vitamin D levels can reduce your risk of having apremature delivery. It can also help protect your newborn baby from other health problems.

In what is considered the first scientific trial that meets the most stringent criteria for “evidence-based inquiry,” US researchers Drs. Hollis and Wagner divulged their findings at a recent international vitamin D research conference in Brugge, Belgium.

Their findings included:

  • Mothers who took 4,000 IU’s (ten times the RDA of 400 IU) of vitamin D during pregnancy had their risk of premature birth reduced by half
  • Premature babies born to women taking high doses of vitamin D were reduced by half at both 32 and 37 weeks, and
  • There were also fewer babies who were born “small for dates”
  • Women taking high doses of vitamin D had a 25 per cent reduction in infections, particularly respiratory infections such as colds and flu as well as fewer infections of the vagina and the gums
  • The “core morbidities of pregnancy” were reduced by 30 per cent in the women who took the high-dose vitamin D (including diabetes, high blood pressure, and pre-eclampsia – a potentially deadly increase in blood pressure and
    fluid)
  • Babies getting the highest amounts of vitamin D after birth had fewer colds and less eczema

Omega-3 and vitamin D linked to 40% reduced risk of macular degeneration

Study shows that consumption of omega-3 fatty acids and omega-3 rich fish could slash the risk of developing age-related macular degeneration (AMD) by 40 per cent.

This study adds further support for increasing the ratio of omega-3 to omega-6 fatty acids with the finding that arachidonic acid (AA, omega-6 fatty acid) is associated with anincreased risk of AMD.

Stroke Survivors Can Improve Balance with Tai Chi

TaiChi Helps Stroke PatientsA new study finds that stroke survivors can improve their balance by practicing the Chinese martial art of tai chi, lessening the risk of a serious fall. Tai chi consists of constant coordinated movement of the head, torso and limbs requiring concentration and balance control.

The study looked at 136 participants in Hong Kong who had suffered a stroke more than six months earlier. Participants were randomly assigned to a tai chi group or to a control group that practiced breathing, stretching and other exercises that involved sitting, walking, memorizing and reasoning.

Participants in the tai chi group were trained in small groups by physical therapists in a weekly class, then practiced at home three days a week for one hour. All participants were then tested for their ability to maintain balance while shifting weight, leaning in different directions, and standing on moving surfaces to simulate a crowded bus. In these tests the tai chi group out-performed the control exercise group, showing significant improvement in just six weeks.

Christina Hui-Chan, professor and head of physical therapy at University of Illinois at Chicago, promotes tai chi as a way to improve balance and minimize falls among healthy elderly subjects. She reports that the benefits of tai chi also include improved strength and cardio fitness. In addition, group classes provide a healthy social gathering for isolated seniors at a fraction the cost of physiotherapy or personal training.

Protective effect found for ginkgo against radiation damage

A report published in the October 11, 2009 issue of the International Journal of Low Radiation added evidence to a protective effect for Ginkgo biloba against radiation damage. Ginkgo biloba is a tree species whose leaves have been used for centuries in Chinese medicine. Ginkgo leaf extract contains antioxidant compounds called ginkgolides and bilobalides which help scavenge free radicals that attack nearly all components of the cell, including DNA.

The researchers found a significant dose-dependent reduction in apoptotic cells among those treated with ginkgo. While radiation-induced apoptosis (cell death) occurred in nearly one third of irradiated cells not treated with ginkgo, the number declined to 5 percent or less in cells treated with the herb.

Editor’s Note: Gingko biloba has also been found to help preserve vision for those with eye diseases such as macular degeneration, glaucoma and diabetic retinopathy. For more related information, go to www.naturaleyecare.com

Leber’s Disease - Gene therapy transforms eyesight

Pennsylvania researchers using gene therapy have made significant improvements in vision in 12 patients with Leber’s disease, a rare inherited visual defect, a finding that suggests it may be possible to produce similar improvements in a much larger number of patients with retinitis pigmentosa and macular degeneration.

The team last year reported success with three adult patients, an achievement that was hailed as a major accomplishment for gene therapy. They have now treated an additional nine patients, including five children, and find that the best results are achieved in the youngest patients, whose defective retinal cells have not had time to die off.

The youngest patient, 9-year-old Corey Haas, was considered legally blind before the treatment began. He was confined largely to his house and driveway when playing, had immense difficulties in navigating an obstacle course and required special enlarging equipment for books and help in the classroom.

Today, after a single injection of a gene-therapy product in one eye, he rides his bike around the neighborhood, needs no assistance in the classroom, navigates the obstacle course quickly and has even played his first game of softball.

The 12 patients had Leber’s congenital amaurosis, which affects about 3,000 people in the United States and perhaps 130,000 worldwide. Victims are born with severely impaired vision that deteriorates until they are totally blind, usually in childhood or adolescence. There is no treatment.

Leber’s is a good candidate for gene therapy because most of the visual apparatus is intact, particularly at birth and in childhood. Mistakes in 13 different genes are known to cause it, but all 12 of the patients suffered a defect in a gene called RPE65. This gene produces a vitamin A derivative that is crucial for detecting light

The study, led by Dr. Katherine A. High, Dr. Albert M. Maguire and Dr. Jean Bennett of those two institutions, enrolled five people in the United States, five from Italy and two from Belgium. Five were children, and the oldest was 44.

Editor’s Note: In addition to the exciting research described above, there are specific nutrients that may help strengthen vision for those with Leber’s Disease

Women with breast cancer have low vitamin D levels

In a new study, it was found that women with breast cancer should be given high doses of vitamin D because a majority of them are likely to have low levels of vitamin D, which could contribute to decreased bone mass and greater risk of fractures, according to scientists at the University of Rochester Medical Center.

Vitamin D is essential to maintaining bone health, and women with breast cancer have accelerated bone loss due to the nature of hormone therapy and chemotherapy.

Weekly supplementation with high doses of vitamin D — 50,000 international units or more improved the levels, according to Peppone’s study.

The U.S. Institute of Medicine suggests that blood levels nearing 32 nanograms per milliliter are adequate.
