Recent Longevity News for the seven days ending 10/16/13. You should consult your doctor if you are taking any medications. 'Love Hormone' May Help Treat Personality Disorder - Medscape, 10/11/13 - "The neuropeptide oxytocin, which has been shown to reduce anxiety in social situations, enhance the recognition of facial expressions, and shift attention from negative to positive information, may decrease social-threat hypersensitivity in women with borderline personality disorder ... the patients with borderline personality disorder showed more and faster initial fixation changes than healthy women and had more saccades to the eyes of angry faces, combined with greater amygdala activation in response to angry faces, compared with the control group" - See Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems. Effects of Soy, Whey Protein Supplementation Post-Exercise - Science Daily, 10/12/13 - "Our main findings demonstrate that 14 days of supplementation with soy protein does appear to partially blunt serum testosterone. In addition, whey influences the response of cortisol following an acute bout of resistance exercise by blunting its increase during recovery" Molecule produced during exercise boosts brain health - Science Daily, 10/10/13 - "a molecule called FNDC5 and its cleavage product, irisin, are elevated by endurance exercise in the brain and increase BDNF expression. On the other hand, mice genetically altered to have low irisin levels in the brain had reduced levels of BDNF ... FNDC5/irisin has the ability control a very important neuroprotective pathway in the brain"
Multivitamins With Minerals May Protect Older Women With Invasive Breast Cancer
- Science Daily, 10/9/13 - "The research was conducted
as part of the Women's Health Initiative Clinical Trials and the Women's Health
Initiative(WHI)Observational Study. Combined, the two studies include data from
161,608 postmenopausal women ages 50 to 79 when they first joined the study ...
A comparison of mortality rates revealed that women with invasive
breast cancer who took
multivitamin/mineral supplements were 30
percent less likely to die from their cancers than women with invasive breast
cancer who hadn't taken the supplements. Could differences between the
multivitamin/mineral users and nonusers account for this finding? The
researchers looked at many possible confounding factors including additional
supplements that the women took, their smoking status, education,
race/ethnicity, weight, depression, alcohol use, physical activity, age at
breast cancer diagnosis, and diabetes. The association between regular use of
multivitamin/mineral supplements and reduced risk of death persisted even after
these factors were taken into account" - See

High
Dietary Intake of Polyphenols Are Associated With Longevity - Science Daily,
10/9/13 - "the first to evaluate the total dietary
polyphenol intake by using a nutritional biomarker and not only a food frequency
questionnaire ... Polyphenols have
antioxidant, antiinflammatory, anticarcinogenic, etc. effects ... based on a
12-year follow-up of a population sample composed by 807 men and women aged 65
or over from Greve and Bagno (Tuscany, Italy) ... the research proves that
overall
mortality was reduced by 30% in participants
who had rich-polyphenol diets (>650 mg/day) in comparison with the participants
who had low-polyphenol intakes (<500 mg/day)" - See grape seed extract at Amazon.com
Amino
acid offers potential therapeutic alternative in psychiatric disorders -
Science Daily, 10/8/13 - "drug discovery is at a near
standstill for treating psychiatric disorders
such as schizophrenia,
bipolar disorder,
depression and common forms of
autism ... According to Professor Berk, there is
now an incontrovertible evidence base that these disorders share
inflammation and oxidative stress as part of
their disease physiology ... The amino acid, NAC,
seems to have multiple effects on all these pathways: it boosts glutathione,
which is the body’s major antioxidant defence; has anti-inflammatory properties;
enhances levels of nerve cell growth proteins and the growth of new neurons; and
reduces cell death pathways. It also appears to reduce dysfunction of
mitochondria ... NAC reduces the core symptoms of schizophrenia including
negative symptoms such as improved apathy, social interaction and motivation. It
also appears to reduce depression in people with bipolar disorder and at this
meeting ... there is intriguing evidence that it reduces cravings in a number of
addictions including cocaine,
cannabis and
cigarette smoking" - See

Tea
Consumption and Depressive Symptoms in Older People in Rural China - J Am
Geriatr Soc. 2013 Oct 1 - "Compared with no or irregular
tea consumption, controlling for age, sex, education, leisure activities, number
of comorbidities, and Mini-Mental State Examination score, the odds ratios of
having high depressive symptoms were 0.86 (95% confidence interval (CI) =
0.56-1.32) for weekly and 0.59 (95% CI = 0.43-0.81) for daily tea consumption (P

Response rates with pasireotide from three prospective studies were 17-29%. The remaining medications were supported by a 'low' or 'very low' level of evidence. The highest response rates were reported in small retrospective studies of metyrapone (75%, one study) and mitotane (72%, one study). Response rates were 25-50% for cabergoline (four studies) and 45% for ketoconazole (one study). Among studies that included patients with other forms of Cushing's syndrome, response rates were 53-88% for ketoconazole (three studies), 70% for mitotane (one study), 57% for metyrapone (one study) and 38-60% for mifepristone. Again, all of these medications are supported by a 'low' level of evidence"

prevents liver carcinogenesis by inducing cell cycle arrest, decreasing cell
proliferation and enhancing apoptosis - Mol Nutr Food Res. 2013 Oct 1 -

model of hepatocarcinogenesis
(initiated-promoted group). Initiated-promoted animals also received
quercetin 10 and 20 mg/kg body weight (IPQ10

Dehydroepiandrosterone-sulfate (DHEAS) promotes MIN6 cells insulin secretion via
inhibition of AMP-activated protein kinase - Biochem Biophys Res Commun.
2013 Oct 8 - "Although it has the property of
anti-diabetes, the long-term effect of DHEAS on
insulin secretion in beta-cells is still unclear. In this study, the effect of
DHEAS on the insulin secretion activity in MIN6 cell lines in vitro was
assessed. Insulin biosynthesis and secretion were stimulated by DHEAS for 24 h.
DHEAS inhibited the AMPK activation and upregulated the expression of ACC-1.
These findings indicate that DHEAS may exert prominent stimulatory effects on
insulin secretion partly via AMPK inhibition and ACC-1 upregulation" -

It is well known that the control of vascular function is highly dependent on the production of nitric oxide (NO) by NO synthases ... Thiamine deficiency modulates eNOS-dependent NO production, leading to a decreased vasorelaxation and an increased contractile response in the rat aorta"
Probiotics
determine hypolipidemic and antioxidant effects in hyperlipidemic hamsters -
Mol Nutr Food Res. 2013 - "probiotic
mix (Lactobacillus acidophilus and Bifidobacterium animalis) ... Male Golden
Syrian hamsters developed hyperlipidemia after 21 weeks of fat diet. For the
last 5 weeks of experiment, ten HL were treated with the probiotic mix (HLP),
ten received water (HL). Ten animals received standard chow (N). Increase of
plasma total cholesterol (TC), triglycerides (TG), phospholipids (PL), oxidized
LDL, glucose, of 4-hydroxynonenal (4-HNE) in plasma, liver, and myocardium, and
of intestinal Niemann Pick C1 like 1 (NPC1L1) and microsomal TG transfer protein
(MTTP) expression was observed in HL versus N. The probiotic mix decreased
plasma TC, TG, PL, oxidized LDL, 4-HNE, and glucose levels and increased
paraoxonase-1 activity, decreased NPC1L1 and MTTP protein expression compared to
HL. In HLP liver, a significant reduction of TC, TG, and fatty acids was
observed. PL increased and 4-HNE levels decreased in the liver and myocardium of
HLP versus HL" - See
