Alcohol-Related Brain Damage - Medscape, 7/25/14 -
"The researchers assessed brain samples from adult male rats exposed during a
period of several days to repetitive ethanol intoxication. Half of the brain
samples were further exposed to omega-3 DHA and the
other half were not ... Results showed higher levels of phospholipase A2 (PLA2)
resulting from the excessive alcohol exposure,
which led to increased neuroinflammation, or astroglial aquaporin-4 (AQP4), and
increased brain edema ... Compared with rats that had not been exposed to
alcohol, those that had been exposed had significantly higher levels of cPLA2
and phospho-CPLA2 in the hippocampus, entorhinal cortex, and olfactory bulb
(all, P < .05). They also had significantly increased levels of sPLA2 in all 3
areas" - See

dementia at baseline in 2004 and followed until 2010. The information on
prescriptions of pioglitazone on a quarterly basis was expressed as a linear

ranged between 0 and 28 quarters ... With each additional quarter of
pioglitazone prescription, the relative risk for dementia fell by 6%" -

D deficiency raises risk of schizophrenia diagnosis - Science Daily, 7/22/14
- "The meta-analysis found that people with
schizophrenia had significantly lower
levels of vitamin D in the blood compared to
the control groups. The average difference in vitamin D levels between
schizophrenic patients and control participants was -5.91 ng/ml. People with
vitamin D deficiency were 2.16 times more likely to have schizophrenia than
those with sufficient vitamin D in their bloodstreams. In addition, 65 percent
of the participants who had schizophrenia also were vitamin D deficient"

"After analyzing the results, the scientists found that
THC increased the likelihood of paranoia
happening ... Half the participants had paranoid thoughts with THC, compared to
just 30% with placebo ... The paranoia declined as the drug left the bloodstream
... The drug also caused a range of other psychological effects: anxiety, worry,
lowered mood, negative thoughts about the self, various changes in perception
(such as sounds being louder than normal and colors brighter), thoughts echoing,
altered perception of time, and poorer short-term memory ... They say it's
likely that paranoia creeps in because THC increases negative feelings, and the
perceptual changes lead to the rise in paranoia"

Plasma T3 is a Biological Priority - Clin Endocrinol (Oxf). 2014 Jul 5 -
"Studies in rodents indicate that different levels of
genetic disruption of the feedback mechanism and deiodinase system are met with
elevation in serum T4 and thyroid stimulating hormone (TSH) levels, while serum
T3 levels remain stable. These findings have focused attention on serum T3
levels in patients with thyroid disease, with important clinical implications
affecting therapeutic goals and choice of therapy for patients with
hypothyroidism. Although monotherapy with
levothyroxine is the standard of care for hypothyroidism, not all patients
normalize serum T3 levels with many advocating for combination therapy with
levothyroxine and liothyronine. The latter could be
relevant for a significant number of patients that remain symptomatic on
monotherapy with levothyroxine, despite normalization of serum TSH levels"

Epigallocatechin-3 Gallate Inhibits Invasion, Epithelial-Mesenchymal Transition,
and Tumor Growth in Oral Cancer Cells - J Agric Food Chem. 2011 Mar 9 -
"Epithelial to mesenchymal transition (EMT) is critical
for the progression, invasion, and metastasis of epithelial tumorgenesis. Here,
we provided molecular evidence associated with the antimetastatic effect of
green tea polyphenol epigallocatechin-3 gallate (EGCG) in an oral squamous cell
culture system by showing a nearly complete inhibition on the invasion (P <
0.001) of squamous cell carcinoma-9 (SCC-9) cells via a reduced expression of
matrix metalloproteinase-2 (P < 0.001) and urokinasetype plasminogen activator
(P < 0.001). EGCG exerted an inhibitory effect on cell migration (P < 0.001),
motility (P < 0.001), spread, and adhesion (P < 0.001). We performed Western
blot to find that EGCG inhibited p-focal adhesion kinase (p-FAK), p-Src,
snail-1, and vimentin, indicating the anti-EMT effect of EGCG in oral squamous
cell carcinoma. EGCG was also sufficient to inhibit
phorbol-12-myristate-13-acetate-induced cell invasion and matrix
metalloproteinase-9 expression, as evidenced by its inhibition on the tumor
growth of SCC-9 cells in vivo via cancer cell xenografted nude mice mode. These
results suggested that EGCG could reduce the invasion and cell growth of tumor
cells, and such a characteristic may be of great value in developing a potential
cancer therapy" - See

Perioperative arginine-supplemented nutrition in malnourished patients with head
and neck cancer improves long-term survival - Am J Clin Nutr. 2010 Sep 29 -
"Plasma arginine concentrations are lower in patients
with cancer, which indicates that arginine metabolism may be disturbed in these
patients. Arginine supplementation has been associated with positive effects on
antitumor mechanisms and has been shown to reduce tumor growth and to prolong
survival. Furthermore, the prognosis of patients with head and neck cancer
remains disappointing. Insufficient intake frequently leads to malnutrition,
which contributes to high morbidity and mortality rates ... The group receiving
arginine-enriched nutrition had a significantly better overall survival (P =
0.019) and better disease-specific survival (P = 0.022). Furthermore, the
arginine-supplemented group had a significantly better locoregional
recurrence-free survival (P = 0.027). No significant difference in the
occurrence of distant metastases or occurrence of a second primary tumor was
observed between the groups" - See

Antioxidant and Mineral Intake in Humans Is Associated with Reduced Risk of
Esophageal Adenocarcinoma but Not Reflux Esophagitis or Barrett' Esophagus -
J Nutr. 2010 Aug 11 - "We found that overall antioxidant
index, a measure of the combined intake of vitamin C, vitamin E, total
carotenoids, and selenium, was associated with a reduced risk of EAC [odds ratio
(OR) = 0.57; 95% CI = 0.33-0.98], but not BE (OR = 0.95; 95% CI = 0.53-1.71) or
RE (OR = 1.60; 95% CI = 0.86-2.98), for those in the highest compared with
lowest category of intake. Those in the highest category of vitamin C intake had
a lower risk of EAC (OR = 0.37; 95% CI = 0.21-0.66; P-trend = 0.001) and RE (OR
= 0.46; 95% CI = 0.24-0.90; P-trend = 0.03) compared with those in the lowest
category. Vitamin C intake was not associated with BE, and intake of vitamin E,
total carotenoids, zinc, copper, or selenium was not associated with EAC, BE, or
RE. In conclusion, the overall antioxidant index was associated with a reduced
risk of EAC. Higher dietary intake of vitamin C was associated with a reduced
risk of EAC and RE. These results suggest that antioxidants may play a role in
the pathogenesis of RE and EAC and may be more important in terms of progression
rather than initiation of the disease process"

"Zinc not only improves cell mediated immune
functions but also functions as an antioxidant and anti-inflammatory agent.
Oxidative stress and chronic inflammation have been implicated in development of
many cancers. In patients with head and neck cancer, we have shown that nearly
65% of these patients were zinc deficient based on their cellular zinc
concentrations. Natural killer (NK) cell activity and IL-2 generation were also
affected adversely ... Zinc status also correlated with number of hospital
admissions and incidences of infections. NF-kappa B is constitutively activated
in many cancer cells, and this results in activation of antiapoptotic genes,
VEGF, cyclin DI, EGFR, MMP-9 and inflammatory cytokines. Zinc inhibits NF-kappa
B via induction of A-20. Thus, zinc supplementation should have beneficial
effects on cancer by decreasing angiogenesis and induction of inflammatory
cytokines while increasing apoptosis in cancer cells. Based on the above, we
recommend further studies and propose that zinc should be utilized in the
management and chemoprevention of cancer" - See
