Silent Spring

Friday, May 25, 2007

"There was once a town in the heart of America where all life seemed to live in harmony with its surroundings." First sentence, Rachel Carson's Silent Spring   The book took its title from the opening chapter, a vision of a rural community rendered silent in springtime - its habitual birdsong silenced by the mass poisoning of all the birds. 

Multivitamin Use and Risk of Prostate Cancer

Friday, May 18, 2007

A study published in the May 16 Journal of the National Cancer Institute (JNCI) on “Multivitamin Use and Risk of Prostate Cancer in the National Institutes of Health–AARP Diet and Health Study” concludes that there was no association observed between multivitamin use and risk of localized prostate cancer. However, the researchers found an increased risk of advanced and fatal prostate cancers among men reporting excessive use of multivitamins (more than seven times per week) when compared with never users.

Proteomics, Exercise and Inflammation

Friday, May 11, 2007

Today’s column addresses questions from our recent ASCRS Eyes on Fire lecture. Proteomic science is changing the way many gerontologists think about inflammation, the aging process and degenerative diseases. The term proteomics was coined as an analogy to genomics, the study of genes. Understanding the structure and function of each protein and the complexities of protein-protein interactions is becoming critical to the development of effective diagnostics, disease treatments and more importantly, degenerative disease prevention including eye disease.  

Genomics, Nutrition & Inflammation

Friday, May 04, 2007

Our genes are formed from microscopic double-strands of deoxyribonucleic acid (DNA). They are dependent on adequate nutrition for their structure and activity. By appropriately switching on and off (this is called transcription in the genome research world) our genes direct the behavior of our body's 60 trillion cells. Many genetic researchers consider our genes to be the Rosetta stone of health and disease.

On Conjecture and Theorems

Tuesday, May 01, 2007

A reclusive Russian mathematician, Grigori Perelman, used the equations of Ricci flow (a process by which topological regions of high curvature flow into regions of lower curvature) to finally prove the daunting 100 year old Poincare Conjecture - arguably one of the most famous unsolved math problems in the world.

Innovation: The Pain, The Pleasure

Friday, April 27, 2007

Robert Stegmann, MD, discussed the pain and the pleasure of living an innovative life as a surgeon when he was awarded the "Sir Harold Ridley Distinguished Visiting Professorship for Creativity and Innovation in Ophthalmology," by Jerre Freeman, MD and Barrett Haik, MD, of the Department of Ophthalmology at the University of Tennessee, Memphis on Wednesday, April 25th, 2007.

Chimps, Chance & Nutritional Status

Friday, April 20, 2007

A study published in a recent Proceedings of the National Academy of Sciences, suggests that since the human-chimp split about 6 million years ago, chimpanzee genes have evolved more than human genes. 

The Eye and Female Symbolism

Friday, April 06, 2007

The renaissance ophthalmologist, Juan Murube, MD, PhD, Professor of Ophthalmology, University of Alcala, Madrid, Spain, president of the International Society of Dacryology and editor of the Sources in Time section of the peer-reviewed journal The Ocular Surface, wrote a most interesting article in the January 2007 edition called The Ocular Surface and Its Symbolism. This week our Friday Pearl column addresses Dr. Murube’s brilliant literary enfeoffment to his readers.

B Vitamin Deficiency: A Preventable Coronary Artery Disease Risk Factor.

Friday, March 30, 2007

The traditional risk factors associated with coronary artery disease (CAD) include diabetes mellitus, hypertension, elevated cholesterol, smoking and a family history of CAD. However, a large amount of recent science suggests hyperhomocysteinemia to be an equally important independent risk factor for CAD, as well as other conditions associated with CAD including pseudoexfoliation glaucoma, diabetic retinopathy, wet macular degeneration, Alzheimer's and erectile dysfunction.

Zinc Daggers - et tu, Brute?

Friday, March 23, 2007

Another variation on our Ides of March theme: Recently published Age-Related Eye Disease (ARED) study data analysis by urology scientists at the University of Wisconsin suggest that hospital admissions in those patients taking 80 mg of zinc oxide are much higher than previously thought. This comes as no surprise to the nutrition science community who has been insisting for years that 80 mg of zinc oxide is far too much for safe daily consumption.
