IDENTIFICATION
OF PERIODONTAL PATHOGENS IN ATHEROMATOUS PLAQUES.
From
a recent study published in the Journal of Periodontology
(2000;71:1554-1560), the official journal of the American
Academy of Periodontology, pathogens have been found in
atheromatous plaques. These pathogens can have an important
role in the progression of atheriosclerosis leading
to coronary vascular disease (=CVD). Therefore the
relationship between periodontal disease and CVD is even more
evident, as already highlighted by the A.A.P. In their web-site,they
mention the increase of CVDiseases and strokes.
ELEVATION OF SYSTEMIC
MARKERS FOR CVD IN PATIENTS WITH PERIODONTAL DISEASE.
This
study has recently appeared in the Journal of Periodontology
October 2000 (2000;71:1528-1534).Periodontal Disease leads
to an increase of inflammatory factors. These factors
can potentially increase the risk for cardiac or cerebrovascular
events.
GROWTH
FACTORS AND CEMENTOBLASTS.
After much alarming news,finally some good news,regarding
tissue regeneration engineering. Periodontal disease
-as you noted from my web-site, or elsewhere- leads to the
destruction of tissues surrounding the teeth.In the Journal
of Periodontology October 2000 (2000;71:1591-1600) a study
revealed that the IGF-I, PDGF-BB, and TGF-Beta factors are
able to influence mitogenesis and the biomineralization
potential of cementoblasts.These factors -used alone or
with other agents- can stimulate cells in tissue re-construction.
We can always have hope for the future. Therefore : "THINK
PINK ! "
STRESS
AND INTER-RELATED MIND / BODY RELATIONSHIPS.
At the "MIND / BODY Medical Institute of Harvard" - an
Institute that studies the relationship between mind and
body - the main interest is focused on the scientific
comprehension of molecules that are released into our bodies
following a Relaxation Response (=RR). Fundamentally,they
are trying to understand :
|
-
|
What
parts of the brain are activated during RR. |
|
-
|
How
RR can be used in patients who suffer from anxiety
or depression. |
|
-
|
How
-after RR- positive events can take place in our bodies,
which are : an increase in the immune defences,a
decrease of heart beat ,blood pressure and muscular
tension.
|
|
-
|
How
RR can succeed in inhibiting the activities of systems
that come into play when we are stressed,such as Sympathetic
Nervous System and the Hypothalamic-Pituatary-Adrenal
Axis.
|
It
is hypothesized that a molecule called nitrous oxide
can cause cellular changes associated to with RR. We only
know about 10% -more or less- about the human brain functions.
Maybe we will eventually learn something more.
The "News" will be updated from time to time. Try to visit
this site periodically, in the same way I will try to return
to Harvard as often as possible, or to obtain information
at a distance. If you can,try to "review" even the static
sections of the web-site itself. As the Latins said : "Repetita
iuvant" (=repeated things,help). And maybe - in this case-
"new things" and "repeated things" will help you make constructive
connections and perhaps prevent more serious problems or costly
cures, dental or non !
