Statin Drug Crestor Slows Artery Plaque - WebMD, 4/1/08 - "A trial of the statin drug Crestor [rosuvastatin] has been halted early due to "unequivocal evidence" that it reduces heart attacks, strokes, and deaths due to cardiovascular disease in people with no signs of heart disease"

Mom's fish intake may boost child's brain power - MSMBC, 4/1/08 - "Preschoolers whose mothers regularly ate low-mercury fish during pregnancy may have sharper minds than their peers ... Oily fish such as tuna, salmon and sardines contain omega-3 fatty acids, which are important in fetal and child brain development. The problem is that fatty fish are more likely to be contaminated with mercury, a metal that is toxic to brain cells, particularly in fetuses and young children"

Elevated AST, ALT Linked to Higher Future Mortality Rate - Medscape, 4/1/08 - "An abnormal AST up to 2 times ULN was associated with a 32% increased risk of death, and more than 2 times ULN was linked to a 78% increase in risk ... An abnormal ALT up to 2 times ULN was associated with a 21% increase in mortality risk, and more than 2 times ULN was associated with a 59% increase in risk ... patients with normal AST or ALT had a lower than expected risk of death (SMR 0.95 for AST and 0.61 for ALT)" - Related study:

• Elevated ALT Levels Predict Risk of Death From Liver Cancer - Medscape, 11/2/06 - "Upper limits of normal range from 30 IU/L to 60 IU/L, depending on the laboratory. "We want to reset it southward of 30 IU/L," ... ALT levels are a reflection of the general vascular condition ... If the level is above 30, then that person probably has a problem — fatty liver or some vascular disease, including occlusive coronary artery disease"

Whole Grains Shrink Belly Fat? - Dr. Weil, 3/31/08 - "the whole grains may have helped by stabilizing the dieters' blood sugar, which in turn may have had a beneficial effect on CRP levels"

New Blood Pressure Medication Has Fewer Side Effects, Global Study Suggests - Science Daily, 3/31/08 - "The study found a new drug telmisartan is as effective as the popular drug ramipril in reducing cardiovascular death in high risk patients and it has fewer side effects" - I've been plugging telmisartan for some time now.  Click here.  See telmisartan at OffshoreRx1.com.

Why The Flu Virus Is More Infectious In Cold Winter Temperatures - Science Daily, 3/30/08 - "At winter temperatures, the virus’s outer covering, or envelope, hardens to a rubbery gel that could shield the virus as it passes from person to person ... At warmer temperatures, however, the protective gel melts to a liquid phase. But this liquid phase apparently isn’t tough enough to protect the virus against the elements, and so the virus loses its ability to spread from person to person"

Autism: Amino acid DMG helps in 42 per cent of cases - HealthWorld Online, 3/29/08 - "organised by the Autism Research Institute ... 42 per cent of them reported major improvements in their condition after taking the supplement ...

Brief, High Doses Of Folate -- B Vitamin -- Blunt Damage From Heart Attack - Science Daily, 3/27/08 - "Long known for its role in preventing anemia in expectant mothers and spinal birth defects in newborns, the B vitamin folate, found in leafy green vegetables, beans and nuts has now been shown to blunt the damaging effects of heart attack when given in short-term, high doses to test animals ... a high dose of folic acid for humans comparable to that given the rats would require an average-size adult to swallow more than 200 one-milligram pills per day, "an impractical and unrealistic regimen, even if the body excretes the excess."" - I debated whether to publish this.  It is a ridiculous amount.

Vitamin B6 and Homocysteine Changes Seen in Women With Rheumatoid Arthritis - Medscape, 3/25/08 - "those with rheumatoid arthritis are deficient in vitamin B6 and have elevated levels of homocysteine ... The vitamin B6 deficit appears to be the result of altered metabolism, not reduced dietary intake ... dietary intake of B vitamins is not decreased in rheumatoid arthritis patients, yet they still show a deficit of vitamin B6. Consistent with this finding, rheumatoid arthritis was also associated with increased levels of homocysteine. None of the subjects in the study were using B vitamin supplements ... Individuals with rheumatoid arthritis may need to get more B vitamins through diet, supplements, or fortified foods"
