Melatonin can be neuroprotective against Parkinson's disease?
Parkinson
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3183139/?tool=pubmed
For brain to optimally produce melatonin at night you need a very dark room (can
not see your hand in front of face) It appears a sleep mask over eyes does help.
Some earlier research had seemed to show light anywhere on body was a problem
but this is in doubt now. Article below from life extension.
Melatonin may protect against Parkinson's disease
The theory that Parkinson's disease has an environmental cause has recently
gained credence. A study published in the December 2000 issue of the journal
Nature Neuroscience demonstrated that the pesticide Rotenone caused Parkinson's
symptoms when administered to rats. The article indicated that Rotenone may
cause the mitochondria, which are the power plants of the cells, to produce
free radicals, thereby causing the damage that leads to Parkinson's disease.
In a study published in the January 1, 2001 issue of the Federation of American
Societies for Experimental Biology or FASEB journal, researchers injected the
neurotoxin 6-hydroxydopamine (6-OHDA) into the right substantia nigra of the
brains of rats. This neurotoxin produces a loss of dopaminergic cells, thereby
creating an experimental model of Parkinson's in the right hemisphere of the
brain of the rats who received the injection, as Parkinson's disease is
characterized by a loss of these cells. The rats exhibited a postural assymetry
which causes rotation away from the the undamaged side of the body, seen as
circling behavior. Rats given melatonin prior to administration of 6-OHDA did
not demonstrate this behavior. Analysis of the affected brain tissue in rats
receiving 6-OHDA who were not protected with melatonin showed a loss of complex
1 activity of mitochondrial phosphorylation enzymes, a reduction of which has
been observed in the substantia nigra of Parkinson's disease patients. However,
the melatonin-treated rats were protected against this loss. The researchers
conclude that a deficit in mitochondrial complex 1 could cause free
radical-induced cell death in Parkinson's disease, both directly and by
decreased ATP synthesis and energy failure, and that melatonin may be useful in the

A little update on insect-borne diseases and travel
Vector-Borne Diseases Pose A Threat to Traveler
Wed, 04/09/14 - 09:20
Vector-borne disease—those carried by insects and small animals (eg, malaria, dengue, yellow fever, and West Nile virus)—affect more individuals each year as globalization, travel, and climate change continue to shift the natural boundaries of these vectors away from their traditional regions. Today, roughly 50% of people living in the Western Hemisphere are at risk.
The chikungunya virus first debuted in the Americans in 2 cases on the island of Saint Martin in December 2013. By the end of March 2014, more than 3000 cases have been confirmed in 10 Caribbean countries.(3)
Researchers are now warning that the virus may soon be classified as an epidemic, particularly as travelers from across the world arrive to Brazil next month for the FIFA World Cup.
Brazil reports the highest incidence of dengue; the dengue and chikungunya viruses are transmitted by the same mosquitoes.(1)
Chikungunya can cause fever and severe joint pain, often in the hands and feet, which can sometimes lead to permanent disability. Mortality can reach 1 in 1000. Symptoms commonly begin within 3 to 7 days.
There is no vaccine or medication to prevent the chikungunya disease. If infected, avoiding mosquito bites will help prevent the spread of the virus.
"We as a world are in some ways more vulnerable than ever," said Tom Frieden, director of the CDC, "and that means that we as a world need to collaborate more effectively than ever so we can build the capacity to find new diseases, outbreaks and threats wherever they emerge promptly, and respond effectively."
Countries in the Americas have had success in the past fighting vector-borne disease. Malaria has gone down 60% and malaria deaths declined by 72% between 2000 and 2012.3 A majority of the progress can be credited to publicly-funded programs controlling mosquitoes and other insects, as well as vaccination campaigns against these illnesses.
In honor of World Health Day 2014, the Pan American Health Organization (PAHO) and the World Health Organization (WHO) (3) urge governments to continue to publicly fund vector-control programs and invest in water sanitation and waste collection. Health authorities say countries should improve monitoring of these diseases as well as drug resistance.
"The successes achieved so far are today being threatened by the expansion of mosquitoes and other vectors into new habitats and by the emergence of insecticide and drug resistance," said Carissa F. Etienne, director of PAHO/WHO.
When traveling in a mosquito-heavy area, individuals should use air conditioning and/or window and door screens, wear repellent on exposed skin, wear long-sleeved shirts and long pants, wear permethrin-treated clothing, empty standing water from outdoor containers, and support local vector control programs. People at increased risk for severe diseases should not travel to areas with ongoing outbreaks.

David Brooks on What Suffering Does
What Suffering Does
(C)New York Times
April 7, 2014
By David Brooks,
Over the past few weeks, I've found myself in a bunch of conversations in which the unspoken assumption was that the main goal of life is to maximize happiness. That's normal. When people plan for the future, they often talk about all the good times and good experiences they hope to have. We live in a culture awash in talk about happiness. In one three-month period last year, more than 1,000 books were released on Amazon on that subject.
But notice this phenomenon. When people remember the past, they don't only talk about happiness. It is often the ordeals that seem most significant. People shoot for happiness but feel formed through suffering.
Now, of course, it should be said that there is nothing intrinsically ennobling about suffering. Just as failure is sometimes just failure (and not your path to becoming the next Steve Jobs) suffering is sometimes just destructive, to be exited as quickly as possible.
But some people are clearly ennobled by it. Think of the way Franklin Roosevelt came back deeper and more empathetic after being struck with polio. Often, physical or social suffering can give people an outsider's perspective, an attuned awareness of what other outsiders are enduring.
But the big thing that suffering does is it takes you outside of precisely that logic that the happiness mentality encourages. Happiness wants you to think about maximizing your benefits. Difficulty and suffering sends you on a different course.
First, suffering drags you deeper into yourself. The theologian Paul Tillich wrote that people who endure suffering are taken beneath the routines of life and find they are not who they believed themselves to be. The agony involved in, say, composing a great piece of music or the grief of having lost a loved one smashes through what they thought was the bottom floor of their personality, revealing an area below, and then it smashes through that floor revealing another area.
Then, suffering gives people a more accurate sense of their own limitations, what they can control and cannot control. When people are thrust down into these deeper zones, they are forced to confront the fact they can't determine what goes on there. Try as they might, they just can't tell themselves to stop feeling pain, or to stop missing the one who has died or gone. And even when tranquillity begins to come back, or in those moments when grief eases, it is not clear where the relief comes from. The healing process, too, feels as though it's part of some natural or divine process beyond individual control.
People in this circumstance often have the sense that they are swept up in some larger providence. Abraham Lincoln suffered through the pain of conducting a civil war, and he came out of that with the Second Inaugural. He emerged with this sense that there were deep currents of agony and redemption sweeping not just through him but through the nation as a whole, and that he was just an instrument for transcendent tasks.
It's at this point that people in the midst of difficulty begin to feel a call. They are not masters of the situation, but neither are they helpless. They can't determine the course of their pain, but they can participate in responding to it. They often feel an overwhelming moral responsibility to respond well to it. People who seek this proper rejoinder to ordeal sense that they are at a deeper level than the level of happiness and individual utility. They don't say, "Well, I'm feeling a lot of pain over the loss of my child. I should try to balance my hedonic account by going to a lot of parties and whooping it up."
The right response to this sort of pain is not pleasure. It's holiness. I don't even mean that in a purely religious sense. It means seeing life as a moral drama, placing the hard experiences in a moral context and trying to redeem something bad by turning it into something sacred. Parents who've lost a child start foundations. Lincoln sacrificed himself for the Union. Prisoners in the concentration camp with psychologist Viktor Frankl rededicated themselves to living up to the hopes and expectations of their loved ones, even though those loved ones might themselves already be dead.
Recovering from suffering is not like recovering from a disease. Many people don't come out healed; they come out different. They crash through the logic of individual utility and behave paradoxically. Instead of recoiling from the sorts of loving commitments that almost always involve suffering,they throw themselves more deeply into them. Even while experiencing the worst and most lacerating consequences, some people double down on vulnerability. They hurl themselves deeper and gratefully into their art, loved ones and commitments.
The suffering involved in their tasks becomes a fearful gift and very different than that equal and other gift, happiness, conventionally defined.
A version of this op-ed appears in print on April 8, 2014, on page A25 of the New York edition with the headline: What Suffering Does.
