Blood Viscosity: The Role of Blood Flow in Cognitive Function

By Ralph E. Holsworth, DO, and Jonathan V. Wright, MD - Vol. 13, No. 2. Summer, 2012

High blood viscosity, a robust predictor of cardiovascular disease risk, is also predictive of cognitive dysfunction in older people, and may be an early indicator of the risk of Alzheimer's disease.

Magnesium Significantly Reduces Blood Pressure

By Erik Goldman

Magnesium supplementation, particularly at doses over 370 mg per day, can significantly reduce both systolic and diastolic blood pressure in hypertensive and pre-hypertensive people, according to a new metanalysis of 22 trials.

 

Lose Weight? You Bet! Men Excel in Weight Loss Wagers

By Erik Goldman
Weight loss wagers, the latest rage among big employers trying to cut health care costs, are proving to be an effective strategy for helping men get into better shape.

Blood Viscosity: The Unifying Parameter In Cardiovascular Disease Risk

By Ralph E. Holsworth, Jr., DO & Jonathan V. Wright, MD - Vol. 13, No. 1. Spring, 2012
Increased blood viscosity is the only biological parameter that has been linked with all of the other major heart disease risk factors, including high blood pressure, elevated LDL cholesterol, low HDL, type-II diabetes, metabolic syndrome, obesity, smoking, age, and male gender. Until recently, technological limitations made it impractical for doctors to measure this key risk factor. Fortunately, that's changing.

Putting PSA Testing in Perspective

By Erik Goldman

The recent Preventive Services Task Force draft recommendation against routine Prostate Specific Antigen (PSA) screening has a lot of guys pissing vinegar, with some calling the new report "a death sentence." More moderate voices call for recognition of the limits of PSA testing while cautioning against sweeping policy moves. Integrative Urologist Dr. Geo Espinosa sheds some light.

Vitamin D Supplementation Cuts All-Cause Mortality in Elderly Women

By DynaMed - Vol. 12, No. 3. Fall, 2011

A Cochrane Collaboration systematic review of 32 clinical trials involving nearly 75,000 elderly women, concludes that daily supplementation with vitamin D3 (cholecalciferol), significantly decrease all-cause mortality.

Jellyfish Protein Shows Promise In Reversing Age-Related Cognitive Decline

By Erik Goldman - Vol. 12, No. 3. Fall, 2011

A protein originally isolated from the Aequorea victoria species of jellyfish, can improve cognitive function in older adults experiencing mild but troublesome impairment.

Is Herpes A Trigger for Alzheimer’s Disease?

By Erik Goldman - Vol. 12, No. 2. Summer, 2011
An emerging line of research is implicating the herpes simplex virus and other infectious pathogens as underlying triggers for formation of β-amyloid plaques in the brain, the hallmark of Alzheimer’s disease. The possibility that there is an infectious component in the development of Alzheimer's opens new possibilities for preventing and treating this devastating disorder.

Telomerase Activation, Inhibition of Cellular Aging Becomes a Clinical Reality

By August West - Vol. 12, No. 2. Summer, 2011

Cellular longevity is governed by telomeres, the DNA caps on the ends of chromosomes. Telomere length is regulated by an enzyme called telomerase. When telomerase activity is high, so is telomere length, and this delays cellular senescence. Substances including Omega 3s, vitamin D and folate have been shown to slow telomere shortening, but until recently researchers had not found anything that could actually activate telomerase and lengthen short telomeres. That changed with the discovery of a unique compound within the root of the Astragalus plant.

Food Sources of Vitamin K

By John Neustadt, ND / Contributing Writer - Vol. 12, No. 1. Spring, 2011

Phylloquinone, a naturally-occurring form of vitamin K, is found in several different types of foods.
