CCTV for Remote Location

From Copenhagen to Cochabamba, via the Amazon
On his way to the World Peoples’ Conference in Bolivia, a member of the Indigenous Environmental Network from the Six Nations in Ontario revisits the scenes of struggle to defend indigenous communities and rights in the Peruvian Amazon.

“The Amazon, it is often said, functions like the lungs of Mother Earth. The dense forest and undergrowth absorb much of the carbon dioxide that we manage to pump into the skies — an ever more important and taxing effort in light of the threats to our climate.
In December, countries around the world gathered in Copenhagen to reach an agreement to protect the climate, even if purely face-saving, and failed. With that sour taste gone, Bolivia has invited governments, social movements, Indigenous Peoples, politicians, really anyone who cares, to attend the so-called World Peoples’ Conference on Climate Change and the Rights of Mother Earth. The conference will be held the 19th-22nd in Cochabamba.
Ahead of that trip, I’ve flown into Lima, Peru to head back into the Amazon. It has been almost a year since the tragic day of June 5th, 2009 left over 30 people dead in the worst violence Peru has seen in modern history. The dispute was over a series of laws the government wanted to push through to open the Amazon to foreign companies, an effort linked to the Free Trade Agreement Peru’s President Alan Garcia signed with Canada and the United States.
Amazon Indigenous Peoples resisted the laws with a blockade outside the town of Bagua, on the outskirts of the Amazon, and the government’s decision to send in armed forces still reverberates here. You can see my coverage from Peru last year here.
Indigenous groups here and elsewhere have maintained that their role in protecting their lands, their resources, their ecologies is paramount, and also serves the rest of humanity. In this case, the Awajun and Wampis peoples were concerned about the entry of oil companies into their lands, ultimately polluting the waters, the flora, the fauna, everything, as has been the case so many times in other parts of the Amazon.
Bagua today is a much different place than in those tense days after June 5th, when military patrols roamed the streets, and a curfew kept people in hiding. Now, the only sense of tension was between teenage boys and girls in the plaza, whistling and blasting around on motorbikes. As they say, calm waters run deep, and the Amazon has a long memory.
I managed to catch up with Salomon Awananch, who since I ran into him [...]

Better Sleep, Better Learning? Obstructive sleep apnea can reduce a child’s IQ by 10 points
From Science Life Blog at the University of Chicago:
Pediatric obstructive sleep apnea, or OSA, can have long-term, detrimental effects on a child’s cardiovascular and respiratory health. But it can also create neurocognitive effects, such as a reduced ability to learn and retain information.
OSA can reduce a child’s IQ by as many as 10 points, while treatment in children with OSA can improve grades.

AGE Precursor Methylglyoxal Also an Issue?
Advanced glycation end-products (AGEs) seem to be important in aging, their buildup effectively a form of damage that harms cellular processes in a number of ways. Here, researchers suggest that an AGE precursor chemical is also problematic: “Oxidative stress is believed to be a very important factor in causing aging and age-related diseases. Oxidative stress is caused by an imbalance between oxidants such as reactive oxygen species (ROS) and antioxidants. ROS are produced from the mitochondrial electron transport chain and many oxidative reactions. Methylglyoxal (MG) is a highly reactive dicarbonyl metabolite formed during glucose, protein and fatty acid metabolism. MG levels are elevated in hyperglycemia and other conditions. An excess of MG formation can increase ROS production and cause oxidative stress. MG reacts with proteins, DNA and other biomolecules, and is a major precursor of advanced glycation end products (AGEs). AGEs are also associated with the aging process and age-related diseases such as cardiovascular complications of diabetes, neurodegenerative diseases and connective tissue disorders. AGEs also increase oxidative stress. In this review we discuss the potential role of MG in the aging process through increasing oxidative stress besides causing AGEs formation. Specific and effective scavengers and crosslink breakers of MG and AGEs are being developed and can become potential treatments to slow the aging process and prevent many diseases.”

On Calorie Restriction Research
This release via ScienceDaily summarizes the goals of present day calorie restriction research: “Organisms from yeast to rodents to humans all benefit from cutting calories. In less complex organisms, restricting calories can double or even triple lifespan. It’s not yet clear just how much longer calorie restriction might help humans live, but those who practice the strict diet hope to survive past 100 years old. … calorie restriction influences the same handful of molecular pathways related to aging in all the animals that have been studied. Aware of the profound influence of calorie restriction on animals, some people have cut their calorie intake by 25 percent or more in hopes of lengthening lifespan. [Researcher Luigi Fontana] is less interested in calorie restriction for longer life than in its ability to promote good health throughout life. … Right now, the average lifespan in Western countries is about 80, but there are too many people who are only healthy until about age 50. We want to use the discoveries about calorie restriction and other related genetic or pharmacological interventions to close that 30-year gap between lifespan and ‘healthspan.’ However, by extending healthy lifespan, average lifespan also could increase up to 100 years of age.”
