exhaust associated with lethargy in offspring - Science Daily, 3/23/10 -
"The researchers speculate that certain components, such
as ultrafine particles, in the diesel exhaust may be translocated into the
offspring of mice, disturbing the normal timetable of development in offspring
and leading to the behavioral and physiological abnormalities seen in this
study. Alternatively, or additionally, diesel exhaust exposure may affect the
mother's behavior toward the pups after birth, which could also cause lethargy
and altered brain chemistry"

growth of new and existing polyps in patients with FAP ... celecoxib has been
associated with harmful cardiovascular side effects in older patients" -

"The role of selenium
diabetes has been controversial, with some
studies suggesting that it raises diabetes risk and others finding that it is
protective. Now, research published in BioMed Central's open access journal
Nutrition and Metabolism, has shown that, for men, high plasma selenium
concentrations are associated with a lower occurrence of
dysglycemia ... for French elderly males,
having plasma selenium concentrations in the top tertile of the population
distribution (1.19-1.97 μmol/L) was significantly associated with a lower risk
of developing dysglycemia over the following nine years ... The reason we
observed a protective effect of selenium in men but not in women is not
completely clear, but might be attributed to women being healthier at baseline,
having better antioxidant status in general and possible differences in how men
and women process selenium" - [Nutra

fat utilization during exercise compared with mice on a normal diet with
prolongation of the running time to exhaustion. Colocalization of fatty acid
translocase with carnitine palmitoyltransferase I (CPT I) in skeletal muscle

modification of CPT I was increased by exercise, while astaxanthin prevented
this increase. In additional experiment, we found that astaxanthin treatment

How much physical activity is enough to prevent unhealthy weight gain?
- Obes Rev 2003 May;4(2):101-14 - "The following
consensus statement was accepted unanimously. 'The current physical activity
guideline for adults of 30 minutes of moderate intensity activity daily,
preferably all days of the week, is of importance for limiting health risks
for a number of chronic diseases including coronary heart disease and
diabetes. However for preventing weight gain or regain this guideline is
likely to be insufficient for many individuals in the current environment.
There is compelling evidence that prevention of weight regain in formerly
obese individuals requires 60-90 minutes of moderate intensity activity or
lesser amounts of vigorous intensity activity. Although definitive data are
lacking, it seems likely that moderate intensity activity of approximately
45 to 60 minutes per day, or 1.7 PAL (Physical Activity Level) is required
to prevent the transition to overweight or obesity. For children, even more
activity time is recommended. A good approach for many individuals to obtain
the recommended level of physical activity is to reduce sedentary behaviour

Exercise When Young May Reduce Risk Of Fractures Later In Life - Science
Daily, 12/7/06 - "Even though the best time to gain
lifetime bone health benefits is while people are young, exercising when
people are older is essential to maintain bone mass and balance, as well as
maintain aerobic fitness, all of which aid in reducing the risk of
low-trauma (osteoporotic) fractures associated with aging"

With Coronary Artery Disease - Medscape, 12/5/06 -
"The VO2max values were lower in subjects with FBG
levels between 126 and 140 and ≥140 mg/dL ... The lower exercise capacity of
patients with CAD with higher FBG levels could theoretically be attributed
to differences in left ventricular dimensions and pump function, ischemia,
or differences in baseline and exercise-induced hemodynamics, compared with
patients with normoglycemia"

Without Weight Loss, Increases Insulin Sensitivity and Postheparin Plasma
Lipase Activity in Previously Sedentary Adults
- Medscape, 3/19/03 - "Exercise, without weight
loss, increases SI [insulin sensitivity] and PHPL activity in previously
sedentary adults, without changing K2 or fasting lipid levels. Furthermore,
increased LPL is associated with a decreased total:HDL
ratio, and an increased LPL:HL ratio is associated with a decreased waist
circumference. Therefore, even modest amounts of exercise in the absence of
weight loss positively affect markers of glucose and fat metabolism in
previously sedentary, middle-aged adults" - I threw this out because
I didn't know that "decreased total:HDL ratio ... is associated with a
decreased waist circumference". This might be a long shot but that sounds
like increasing insulin sensitivity via such methods as
metformin and increasing HDL via supplements such as
niacin might decrease

activity ... The study has a drawback, though, that all such studies face,
which is what's called a "healthy patient bias." In this case, women who
exercise often might be more apt to take care of themselves in other ways,
so that a decrease in breast cancer later in life may not be due to the
exercise itself, but rather some other associated factor. The researchers
accounted for this by factoring in subjects such as smoking history and
weight. "After adjusting for all these factors we're pretty confident that
what we see is the effect of exercise,""
