'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 Garden of Life, Vitamin Code, 50 & Wiser Women 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 n-acetyl cysteine at Amazon.com.

Efficacy of medical treatment in Cushing's disease: a systematic review - Clin Endocrinol (Oxf). 2013 Oct 1 - "Pasireotide was the only treatment to be assessed in a randomized trial and was supported by a 'moderate' level of evidence. 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"

Quercetin prevents liver carcinogenesis by inducing cell cycle arrest, decreasing cell proliferation and enhancing apoptosis - Mol Nutr Food Res. 2013 Oct 1 - "Adult male Wistar rats were subjected to a two-phase model of hepatocarcinogenesis (initiated-promoted group). Initiated-promoted animals also received quercetin 10 and 20 mg/kg body weight (IPQ10 and IPQ20 groups, respectively). Antioxidant defenses were modified by quercetin administration at both doses. However, only IPQ20 group showed a reduction in number and volume of preneoplastic lesions. This group showed increased apoptosis and a reduction in the proliferative index" - See quercetin at Amazon.com.

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" - See DHEA at Amazon.com.

Thiamine deficiency leads to reduced nitric oxide production and vascular dysfunction in rats - Nutr Metab Cardiovasc Dis. 2013 Oct 5 - "Thiamine deficiency is a condition that is known to cause damage to the nervous and cardiovascular systems because it interferes with cellular metabolism. 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 probiotic products at Amazon.com.
