Do Statins Protect Against
Glaucoma? - Medscape, 5/13/13 - "open-angle
glaucoma (OAG) ... used a nationwide healthcare claims database containing
detailed medical records for more than 500,000 patients with hyperlipidemia to
determine whether an association exists between
statin use and the development of OAG ... the risk for OAG decreased 0.3%
(adjusted hazard ratio [HR], 0.997; 95% confidence interval [CI], 0.994-0.999)
for every additional month of statin use. Individuals with hyperlipidemia who
took statins continuously for 2 years had an 8% (adjusted HR, 0.922; 95% CI,
0.870-0.976) lower OAG risk compared with those who received no statin therapy"
World
first clinical trial supports use of Kava to treat anxiety - Science Daily,
5/13/13 - "Existing medications have a modest clinical
effect and new effective options were needed for patients with
anxiety ... Unlike some other options it has
less risk of dependency and less potential for side effects ... Following the
completion of the controlled phase, 26 per cent of the
Kava group were classified as in remission from their symptoms compared to
six per cent of the placebo group ... Kava was also well tolerated. Results
showed no significant differences across the two groups for liver function which
had previously been a concern for Kava's medicinal use. In addition there were
no considerable adverse reactions that could be attributed to Kava and no
difference in withdrawal or addiction between the groups ... An additional novel
finding of the study ... Kava increased women's sex drive compared to those in
the placebo group" - See

Intranasal Oxytocin
Normalizes Core ASD Deficit - Medscape, 5/10/13 -
"In autism, there are 3 basic deficits — social
communication, repetitive behavior, and fixated or restricted interest, where
children get fixated on a particular pattern or sensory stimulation and have
difficulty paying attention to other, more socially relevant cues ...
oxytocin has some effect on all 3 aspects of
autism behavior, including now fixated interest ... ASD children process facial
emotions differently from typically developing children, and if they are missing
out on information about facial emotion, "that is a lot of information they're
not able to take in, so this may have a cascading effect on developing
appropriate emotional responses,"" - See

Carnitine Supplement May Improve Survival Rates of Children With Heart Defects
- Science Daily, 5/8/13 - "The new study indicates that
even without fixing the heart defect, high daily doses of
carnitine in the first four weeks of life can prevent endothelial
dysfunction. In fact, the laboratory lambs' ability to make nitric oxide is
preserved even without the benefit of heart surgery and the responses to the
chemical activity that enables blood vessel dilation is normalized"
Soy and
tomato may be effective in preventing prostate cancer - Science Daily,
5/8/13 - "From the time they were 4 to 18 weeks old, the
animals were fed one of four diets: (1) 10 percent whole tomato powder; (2) 2
percent soy germ; (3) tomato powder plus soy germ;
and (4) a control group that ate neither tomato nor soy ... Eating tomato, soy,
and the combination all significantly reduced
prostate cancer incidence. But the combination gave us the best results.
Only 45 percent of mice fed both foods developed the disease compared to 61
percent in the tomato group, and 66 percent in the soy group ... The results of
the mouse study suggest that three to four servings of tomato products per week
and one to two servings of soy foods daily could protect against prostate
cancer" - See

A low
dietary ratio of omega-6 to omega-3 Fatty acids may delay progression of
prostate cancer - Nutr Cancer. 2013;65(4):556-62 -
"High amounts of omega-6 fatty acids
have been linked with increased prostate cancer
risk, whereas omega-3 fatty acids have been
shown to inhibit PCa growth. However, because omega-3 and omega-6 are both
essential fatty acids and part of a complete diet, it is more relevant to
determine the ideal ratio of the two that would allow patients to benefit from
the therapeutic properties of omega-3 fatty acids. LNCaP prostate cancer cells
were treated with dietary-based ratios of omega-6 to omega-3 fatty acids under
hormone-deprivation conditions, and effects on various cellular processes were
determined. A low omega-6 to omega-3 PUFA ratio can delay the progression of
cells toward castration-resistance by suppressing pathways involved in prostate
cancer progression, such as the Akt/mTOR/NFκB axis. It also suppresses the
expression of cyclin D1, and activation of caspase-3 and annexin V staining
shows induction of proapoptotic events. Taken together, our data demonstrates
that maintaining a low omega-6 to omega-3 fatty acids ratio can enhance efficacy
of hormone ablation therapy" - See

Supplementation with selenium-enriched yeast attenuates brain metastatic growth
- Nutr Cancer. 2013;65(4):563-70 - "Mice were fed
experimental diets enriched (1 mg/kg) with sodium selenite (Se-S),
seleno-1-methionine (Se-Meth), a yeast-derived organic form of
selenium (Se-Yeast), or a control diet (Se <
0.05 mg/kg) for 20 wk ... Mice bearing brain
metastatic tumors and fed Se-Yeast- or Se-S-enriched diets displayed a
higher survival rate compared with other experimental and control groups.
Importantly, Se-Yeast supplementation decreased the growth of brain metastatic
tumors as determined by the measurement of the intensity of the bioluminescent
signal emitted by K1735-Luc cells upon reaction with luciferin. Different
chemical forms of Se have distinct effects on the development of brain
metastases. Organic Se in the form of Se-Yeast may be a valuable agent in
suppression of brain metastatic disease" - See

Oxytocin, Social Sharing and Recovery from Trauma - Science Daily, 12/18/12
- "'social sharing of emotions' (SSE) ... SSE, like the
neuropeptide oxytocin (OT) -- known variously as 'the hug hormone', 'the moral
molecule' and 'the natural love drug' -- has a calming and bonding function in
humans. So a team of researchers decided to examine whether it followed that
administering oxytocin might ease this therapeutic and powerful 'social sharing
of emotions' ... What they found was that OT did not make people more talkative
-- the word counts in the letters were the same -- but it did increase the
participants' willingness to share the specific component that is responsible
for the therapeutic effects of social sharing: emotions. As the researchers
note, "the findings are the more remarkable because they were obtained among
men, who may be less inclined than women to express their emotions." ... there
may be further implications for human health, related to OT's antagonistic
effect on the stress hormone cortisol"

their parental engagement, with parallel effects observed in their infants ...
The fathers received the nasal sprays in a solitary room while their infant was
cared for in another room. After 40 minutes, fathers and infants were reunited
and engaged in face-to-face play that was micro-coded for parent and child's
social behavior ... after oxytocin administration, fathers' salivary oxytocin
rose dramatically, more than 10 fold, but moreover, similar increases were found
in the infants' oxytocin. In the oxytocin conditions, key parenting behavior,
including father touch and social reciprocity, increased but infant social
behavior, including social gaze and exploratory behavior, increased as well"

The 'Love Hormone' as Sports Enhancer - NYTimes.com, 11/21/12 -
"Until recently, though, scientists had not considered
whether a substance that promotes cuddliness and warm, intimate bonding might
also play a role in competitive sports ... Being part of a team involves
emotions, as for instance when a team scores, and these emotions are associated
with brain chemicals ... when one of the first shooters threw his arms in the
air to celebrate a goal, his teammates were far more likely to subsequently
shoot successfully than when no exuberant gestures followed a goal ... Oxytocin
facilitates the ability to read other people’s emotions, and it deepens bonds
between group members and heightens suspicion of and antagonism toward those
outside the group"

The Body Odd - Frozen with fear? How the love hormone gets you moving -
MSNBC, 2/13/12 - "a new study shows how the brain
speedily delivers the hormone oxytocin — which
new mothers have in elevated levels, starting with childbirth — to where it's
needed, freeing them to protect their young. ... The study, done in rats,
revealed that oxytocin rushes to the brain region governing fear ... The
findings "could have implications for autism, anxiety and fear disorders," ...
Oxytocin's dampening effect on fear is especially relevant for lactating
mothers, who have high oxytocin levels, and can best defend their offspring from
a threat when not frozen in terror. Similarly, during childbirth, elevated
oxytocin delivery to the amygdala "may be important in reducing anxiety and fear
levels,"

schizophrenia ... They found a clear correlation between the levels of oxytocin
and the amount of attention each new mother paid to her baby. The first
trimester of the pregnancy turned out to be the most important because higher
levels of the hormone during that period coincided with much more bonding and
affection after the birth ... At about the same time as the Israel study, Paul
Zak of Claremont University in California was giving doses of oxytocin, and a
placebo, to participants who were instructed to split a sum of money with a
stranger. The results were "overwhelming," according to that study. Those given

New
role for hormone oxytocin in brain - Science Daily, 11/2/11 -
"Much of the body's chemistry is controlled by the
brain -- from blood pressure to appetite to food metabolism ... a team of
scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed
the exact structure of one crucial brain area in which biochemical commands
are passed from the brain cells to the bloodstream and from there to the
body. In the process, they discovered a surprising new role for the "hormone
of love," showing that it helps to direct the development of this brain
structure ... The scientists showed that oxytocin, one of the two major
hormones secreted in the adult neurohypophysis, is involved in the
development of this brain area already in the embryo. At this stage, the
oxytocin governs the formation of new blood vessels" - Note: I'm

people produce less oxytocin as they get older, so for them to stay
intimate, a supplement can be a godsend.” ... But while some couples swear
by the supplement, experts caution that there’s not enough evidence to show
that synthetic oxytocin — the kind sold over-the-counter, as opposed to that
produced by the human body or used by hospitals to induce labor — can
actually impact the brain" - Related article:

reliable partners—that is, they offered more money to the computer and the
reliable partner than did volunteers who received the placebo nasal spray.
However, OT did not have an effect when it came to sharing with a seemingly
unreliable partner—the volunteers were not generous towards a potentially
unreliable partner, regardless of which nasal spray they received. ... These
findings suggest that OT fosters trust, but not gullibility: OT may make
individuals more trusting, but only in certain situations"

Happily ever after? It's all in your head - CNN, 2/14/02 - See the
video. Claims that love is dependent on a cocktail of chemicals (dopamine,
norepinephrine and
PEA) and that
oxytocin is responsible for bonding and that
vasopressin is responsible for monogamy.
- When It Comes to
Love, the Nose Knows - WebMD, 2/14/01 -
"Oxytocin is the hormone thought to be responsible
for this phase of love, as well as for mother-child bonding. Fallon calls it
the "cuddling hormone," as it is released by touch "done with the right
rhythm and pressure.""

Oxytocin facilitates protective responses to aversive social stimuli in
males - Proc Natl Acad Sci U S A. 2012 Oct 16 -
"Our results therefore show that OXT can potentiate the protective and
mnemonic impact of aversive social information despite reducing amygdala
activity, and suggest that the insula may play a role in emotional
modulation of memory"

link between oxytocin and serotonin in humans: Supporting evidence from
peripheral markers - Eur Neuropsychopharmacol. 2012 Jan 30 -
"Pharmacological studies indicate a functional
interaction between the serotonergic and oxytocinergic systems. In
particular, some selective serotonin (5-HT) reuptake inhibitors, such as
citalopram and fluvoxamine, seem to exert part of their antidepressant
effects through oxytocin (OT) release. Further, the administration of
fenfluramine, a serotonergic agonist, to healthy subjects increases plasma
OT levels. Interestingly, immunocytochemical and double-immunofluorescent
techniques revealed a high degree of overlap between 5-HT transporter
(SERT)-labeled fibers and OT-containing cells ... This result represents the
first evidence of an interaction between OT and SERT, as measured by
[(3)H]-Par binding, at peripheral levels in humans. Given the several
activities mediated by both OT and 5-HT, such a relationship might provide
new perspectives and insights into psychiatric disorders and/or social
relationship disturbances, as well as novel treatment strategies overcoming
and/or integrating the serotonergic paradigm"

Oxytocin
Mediates Social Neuroprotection After Cerebral Ischemia - Stroke. 2011
Sep 29 - "In the present study, adult male mice were
socially isolated (housed individually) or socially paired (housed with an
ovariectomized female); social pairing increased hypothalamic OT gene
expression. To determine whether a causal relationship exists between
increased OT and improved stroke outcome, mice were treated with exogenous
OT or OT receptor antagonist beginning 1 week before induction of
experimental stroke via middle cerebral artery occlusion ... Relative to
social isolation, social housing attenuated infarct size, neuroinflammation,
and oxidative stress following experimental stroke; the neuroprotective
effect of social housing was eliminated by receptor antagonist treatment. In
contrast, administration of OT to socially isolated mice reproduced the
neuroprotection conferred by social housing. We further report evidence for
a direct suppressive action of OT on cultured microglia, which is a key
instigator in the development of neuroinflammation after cerebral ischemia"
