Nutrient Supports Bone Health Over Time - Science Daily, 1/20/09 - "The results suggest there is a protective effect of carotenoids, particularly of lycopene, against bone loss in older adults. The researchers concluded that carotenoids may explain, in part, the previously observed protective effects of fruit and vegetable consumption on bone mineral density" - See Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com.

New Therapeutic Properties Of N-acetyl-L-cysteine Discovered - Science Daily, 1/19/09 - "N-acetyl-L-cysteine (NAC) combined with mesalamine produces a significant improvement in patients suffering from ulcerative colitis ... N-acetyl-L-cysteine, is a drug normally used for the treatment of chronic obstructive pulmonary disease (COPD) and to minimize the effects of cold and flu. Its hepatic protective properties also make this drug a useful tool in paracetamol intoxications ... N-acetyl-L-cysteine reduced the negative effects caused by azathioprine, a immunosuppressant of clinical use, on the liver" - See n-acetyl cysteine at Amazon.com.

Declining Male Fertility Linked To Water Pollution - Science Daily, 1/18/09 - "The study identified a new group of chemicals that act as ‘anti-androgens’. This means that they inhibit the function of the male hormone, testosterone, reducing male fertility. Some of these are contained in medicines, including cancer treatments, pharmaceutical treatments, and pesticides used in agriculture. The research suggests that when they get into the water system, these chemicals may play a pivotal role in causing feminising effects in male fish" - See water distillers at Amazon.com.

Better skin from the beauty aisle - MSNBC, 1/18/09 - Has a doctor's evaluation of various skin aging solutions.

Salt Reduction May Offer Cardioprotective Effects Beyond Blood Pressure Reduction - Science Daily, 1/16/09 - "sodium reduction is beneficial for people who have normal blood pressure and those who are overweight or obese, and the benefits start in just a few weeks"

Genistein Safely Improves Bone Formation in Osteopenic, Postmenopausal Women - Medscape, 1/14/09 - "Usually, the drugs used in the management of osteopenia/osteoporosis have been classified as predominantly 'antiresorptive agents' or as 'bone-forming agents' but, on the basis of our results, genistein might represent the first therapy that overcomes this classification by combining a powerful bone-forming as well as an antiresorptive activity ... All postmenopausal women with bone loss would be ideal candidates for genistein aglycone treatment ... Genistein aglycone has a good safety profile, and in addition it is effective against climacteric syndrome (i.e., hot flushes and night sweats)"

Midlife Coffee And Tea Drinking May Protect Against Late-life Dementia - Science Daily, 1/14/09 - "coffee drinkers at midlife had lower risk for dementia and AD later in life compared to those drinking no or only little coffee. The lowest risk (65% decreased) was found among moderate coffee drinkers (drinking 3-5 cups of coffee/day). Adjustments for various confounders did not change the results. Tea drinking was relatively uncommon and was not associated with dementia/AD"

Newer Antipsychotic Drugs Increase the Risk of Sudden Cardiac Death - WebMD, 1/14/09 - "because these older agents cause movement disorders in some patients, they have largely been replaced with newer medications such as Zyprexa, Risperdal, and Seroquel ... Although the study's results reaffirmed that people who use the older antipsychotic drugs are twice as likely as nonusers to have sudden cardiac death, it also showed a similar increase in risk for the newer medications. For these, the rate of sudden cardiac death was more than twice that for nonusers"

Physical Activity Improves Mood For People Serious Mental Illness - Science Daily, 1/14/09 - "even meager levels of physical activity can improve the mood of people with serious mental illnesses (SMI) such as bipolar disorder, major depression and schizophrenia"

All the participants had elevated levels of high-sensitivity C-reactive protein (hsCRP) ... Over an average of two years of treatment, participants who took the statin Crestor had half as many heart attacks, strokes, and deaths from cardiovascular causes as participants randomly assigned to receive a placebo"

Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

Quercetin up-regulates paraoxonase 1 gene expression with concomitant protection against LDL oxidation - Biochem Biophys Res Commun. 2009 Jan 10 - "Compared to the pair-fed control group, feeding quercetin (10mg/L) in the liquid diet for 4 weeks increased (a) hepatic expression of PON1 by 35% (p<0.01), (b) serum and liver PON1 activities by 29% (p<0.05) and 57% (p<0.01), respectively, and (c) serum homocysteine thiolactonase (HCTL) activity by 23% (p<0.05). Correspondingly, the lag time of low-density lipoprotein (LDL) oxidation was increased by >3-fold (p<0.001) with plasma HDL from quercetin-fed group compared to the HDL from control group. Our data suggest that quercetin has antiatherogenic effect by up regulating PON1 gene expression and its protective capacity against LDL oxidation" - See quercetin at Amazon.com.
