Linked to Breast Cancer Risk - Medscape, 8/5/13 -
"Women who had taken
blockers for 10 years or more had more than double the usual risk for
invasive ductal breast carcinoma (IDC) (odds ratio [OR], 2.4) and for invasive
lobular breast carcinoma (ILC) (OR, 2.6). The researchers also observed a
possible association between the long-term use of ACE inhibitors and reduced
risks for both IDC (OR, 0.7) and ILC (OR, 0.6), although the risk estimate for
IDC was within the limits of chance ... The mechanism behind the apparent
calcium-channel blocker effect is not known ... but some researchers suspect
that these drugs might increase cancer risk by inhibiting apoptosis ... If the
2- to 3-fold increase in risk found in this study is confirmed, long-term
calcium-channel blocker use would take its place as one of the major modifiable
risk factors for breast cancer. Thus it is
important that efforts be made to replicate the findings"
Potential Role of 'Love Hormone' Oxytocin in Brain Function Revealed -
Science Daily, 8/4/13 - "Oxytocin
has a remarkable effect on the passage of information through the brain ... It
not only quiets background activity, but also increases the accuracy of
stimulated impulse firing ... Children and adults with autism-spectrum disorder
(ASD) struggle with recognizing the emotions of others and are easily distracted
by extraneous features of their environment ... oxytocin increased the
reliability of stimulated impulses -- good for brain function, but quite
unexpected ... it is encouraging to find that a naturally occurring neurohormone
can enhance brain circuits by dialing up wanted signals while quieting
background noise" - See

hormone' oxytocin: Difference in social perception between men and women -
Science Daily, 7/31/13 - "oxytocin
improved the ability of all the participants to better interpret social
interactions in general. When the researchers examined the differences between
the sexes they discovered that following treatment with oxytocin, men's ability
to correctly interpret competitive relationships improved, whereas in women it
was the ability to correctly identify kinship that improved" - See

Cancer Cells' Sugar Craving Is Target for New Type of Treatment - Science
Daily, 7/31/13 - "A key feature of cancer cells is they
gorge on sugar from the blood, greedily processing it as a fuel supply which
triggers CtBPs to bind together, forming pairs known as dimers that enable cells
to grow and multiply out of control"

extreme calorie restriction ... Metformin is one
of the most widely prescribed treatments for type-2 diabetes, which occurs
mainly in people above the age of 40. It is also used to treat metabolic
syndrome, a combination of diabetes, high blood pressure and obesity ... The
scientists gave one of two different doses of metformin to middle-aged male mice
and found that lower doses increased lifespan
by about 5%, and also delayed the onset of age-associated diseases" -

IPSS question 7 (nocturia) decreased significantly from 2.88 before starting
ramelteon to 2.41 one month after starting the medication (P = 0.03). The mean
total OABSS decreased significantly from 6.31 to 5.38 (P = 0.03), and the mean
for OABSS question 2 (nighttime frequency of nocturia) also significantly

low serum potassium concentration or low
dietary potassium intake can result in many metabolic disorders ...
cross-sectional study in 10,341 participants aged 40 years or older ... The
prevalence rate of metabolic syndrome was 51.7%

reduction of serum potassium quartiles, participants were tended to have higher
level of triglycerides and uric acid, lower level of high-density lipoprotein
cholesterol (HDL-C), larger waist circumference and more severe insulin

essential nutrient, potassium is safe when taken at appropriate dosages. If
you take a bit too much, your body will simply excrete it in the urine.
However, people who have severe kidney disease cannot excrete potassium
normally and should consult a physician before taking a potassium
supplement. Similarly, individuals taking potassium-sparing diuretics (such
as spironolactone), ACE inhibitors (such as captopril), 14-18 or

behavior and dendritic spine density of posterodorsal medial amygdala neurons in
oxytocin knockout female mice - Behav Brain Res. 2013 Jul 29 -
oxytocin (OT) and arginine-vasopressin (AVP)
have been shown to play an important role in sexual behavior and neuroendocrine
secretion in rodents ... This study aimed to analyze the role of OT in sexual
behavior, the number of oocytes and the density of dendritic spines in the
posterodorsal medial amygdala (MePD) of female mice with selective deletion of
the OT gene (OTKO). Female C57BL/6 mice were genotyped and divided into control
(WT) and OTKO groups (n= 11 each) ... Our data suggest that OT plays a crucial
role in the sexual behavior display, number of released oocytes and density of
dendritic spines in the MePD of female mice" - See

administration alters HPA reactivity in the context of parent-infant interaction
- Eur Neuropsychopharmacol. 2013 Jul 29 - "The
neuropeptide oxytocin (OT) and the steroid
cortisol (CT) have each been implicated in
complex social behavior, including parenting,
and one mechanism by which OT is thought to exert its pro-social effects is by
attenuating hypothalamic-pituitary-adrenal (HPA) response to stress ... we
examined the effects of intranasal OT administered to the parent on parent's and
infant's CT levels following parent-child interaction that included a social
stressor ... 35 fathers and their 5-month-old infants were observed in a
face-to-face-still-face paradigm twice, one week apart ... OT increased fathers'
overall CT response to the stress paradigm. Furthermore, OT altered infants'
physiological and behavioral response as a function of parent-infant synchrony.
Among infants experiencing high parent-infant synchrony, OT elevated infant HPA
reactivity and increased infant social gaze to the father while father
maintained a still-face. On the other hand, among infants experiencing low
social synchrony, parental OT reduced the infant's stress response and
diminished social gaze toward the unavailable father. Results are consistent
with the "social salience" hypothesis and highlight that OT effects on human
social functioning are not uniform and depend on the individual's attachment
history and social skills" - See

Assessing insulin resistance can inform about breast cancer risk - Science
Daily, 4/4/13 - "When tissues become resistant to the
action of insulin -- which occurs often in obese people -- a balancing mechanism
further increases insulin production leading to a chronic hyperinsulinemia. Such
high insulin levels can be detrimental to the body because insulin not only
regulates glucose metabolism but has more functions such as stimulating cell
proliferation and survival. Therefore the continuous activation of insulin
pathways can contribute to cancer development by fuelling cancer cell growth.
Consistently, by analyzing a cohort of 410 patients and 565 healthy women, the
researchers found that 49% of patients were insulin resistant compared with 34%
of controls indicating that insulin resistance can indeed increase the risk of
developing breast cancer"

Diabetes linked to cognitive impairment in older adults, study suggests
- Science Daily, 11/8/11 - "in older patients with
diabetes, two adhesion molecules -- sVCAM and sICAM -- cause inflammation in
the brain, triggering a series of events that affect blood vessels and,
eventually, cause brain tissue to atrophy. Importantly, they found that the
gray matter in the brain's frontal and temporal regions -- responsible for
such critical functions as decision-making, language, verbal memory and
complex tasks -- is the area most affected by these events ... at the age of
65, the average person's brain shrinks about one percent a year, but in a
diabetic patient, brain volume can be lowered by as much as 15 percent ...
Diabetes develops when glucose builds up in the blood instead of entering
the body's cells to be used as energy. Known as hyperglycemia, this
condition often goes hand-in-hand with inflammation ... Once chronic
inflammation sets in, blood vessels constrict, blood flow is reduced, and

Low-carbohydrate, high-protein diets may reduce both tumor growth rates and
cancer risk - Science Daily, 6/14/11 - "The
first diet, a typical Western diet, contained about 55 percent carbohydrate,
23 percent protein and 22 percent fat. The second, which is somewhat like a
South Beach diet but higher in protein, contained 15 percent carbohydrate,
58 percent protein and 26 percent fat. They found that the tumor cells grew
consistently slower on the second diet ... As well, mice genetically
predisposed to breast cancer were put on these two diets and almost half of
them on the Western diet developed breast cancer within their first year of
life while none on the low-carbohydrate, high-protein diet did.
Interestingly, only one on the Western diet reached a normal life span
(approximately 2 years), with 70 percent of them dying from cancer while
only 30 percent of those on the low-carbohydrate diet developed cancer and
more than half these mice reached or exceeded their normal life span ...
tumor cells, unlike normal cells, need significantly more glucose to grow
and thrive. Restricting carbohydrate intake can significantly limit blood
glucose and insulin, a hormone that has been shown in many independent
studies to promote tumor growth in both humans and mice"

Prehypertension is associated with insulin resistance - QJM. 2009 Aug 7
- "All subjects received a 75-g oral glucose
tolerance test (OGTT) for the measurements of IR. RESULTS: The
prehypertensive subjects were more obese and had higher levels of fasting
triglycerides and 2-h insulin than the normotensives. The subjects with
prehypertension were more insulin resistant than the counterparts, indicated
by lower insulin sensitivity index, ISI(0,120), values. While there was no
difference between the two groups in insulin response of OGTT after
adjustments for confounders, the prehypertension group maintained
significant between-group differences in glucose response even when the
incremental insulin levels were added to covariates for adjustments.
DISCUSSION: Our data show that prehypertension is associated with IR. The
subjects with prehypertension have clinical characteristics of the IR
syndrome. It seems that the prehypertension group cannot handle oral glucose
challenge as well as the normotension, probably a consequence of IR in

Diabetes Drug Shows Promise In Fighting Lethal Cancer Complication -
Science Daily, 9/24/09 - "in an animal study, a
diabetes drug that promotes insulin sensitivity slowed the progression of
muscle wasting and fat loss, the main consequences of a syndrome called
cachexia ... Research suggests that cachexia is responsible for between
one-fifth and one-third of all cancer deaths ... These data provide evidence
that in mice with colon cancer tumors, insulin resistance may be involved in
the development of cachexia rather than occur as a result of cachexia ...
Within eight days, the mice with cancer receiving the rosiglitazone showed
more sensitivity to insulin than did the mice with tumors that received no
medication. The insulin sensitivity of the medicated mice matched that of
mice without tumors ... In addition to stopping fat and muscle loss, the
rosiglitazone also dramatically reduced two biological markers present when
proteins break down, particularly in muscles, and a third marker that
indicates cells are eating their own amino acids in an attempt to survive"
- Note: I don't know why they did this study with rosiglitazone. That's

drugs have been established as being effective in preventing diabetes in
subjects with prediabetes. The Diabetes Prevention Program revealed that
metformin 850 mg b.i.d. reduced the risk of diabetes by 31%. The STOP-NIDDM
(Study To Prevent Non-Insulin-Dependent Diabetes Mellitus) trial (n = 1429)
showed that acarbose 100 mg t.i.d. with meals decreased the incidence of
diabetes by 36% when the diagnosis was based on 2 oral glucose tolerance
tests. The XENDOS (Xenical in the Prevention of Diabetes in Obese Subjects)
study examined the use of orlistat, an antiobesity drug, as an adjunct to an
intensive lifestyle modification program in obese non-diabetic subjects.
Orlistat treatment resulted in a 37% decline in the development of diabetes.
More recently, the DREAM (Diabetes Reduction Assessment with Ramipril and
