Mitochondria : Our Biological Clocks

Tue, 19 Aug 2008 15:28:45 GMT

clipped by: bellapria

Why do we age? Can we stop or slow our aging? Can age-associated diseases such as Alzheimer’s, heart disease and cancer be prevented or their symptoms delayed? Only recently has science developed the tools to delve into the intricacies these questions raise.

Functions of Mitochondria

The mitochondria – the organelles within our cells, where energy, in the form of the chemical ATP, is produced - are a serious focus for scientists involved in aging research. Healthy, robust mitochondria are essential for a long healthy life. New research sheds more light on how the mitochondria affect our health and our lifespan. But first a little history of why these organelles are believed to play a role in aging and in the development of age-associated diseases.

New 'arsenic-breathing' bacteria found

clipper's remarks: While arsenic may be toxic because of the way it substitutes phosphorous in the process of burning energy, I don't recall boiling water being too healthy either.
When life on earth was just kicking off, there was little free oxygen, and plenty of boiling water. Arsenic based photosynthesis is likely to have been working long before the green/chlorophyll based photosynthesis evolved.

Scientists have found a new microbe that lives in hot springs and uses arsenic, a substance that is toxic to most life forms, instead of oxygen for photosynthesis.

The new organisms, found floating in Mono Lake in California, are reported in today's issue of the journal Science.

Since the 1990s, scientists have discovered about 20 species of bizarre bacteria that "breathe" arsenic.

"Just like you and I inhale oxygen and breathe out carbon dioxide, these bugs breathe in Arsenic (III) and breathe out Arsenic (V)," says researcher Ronald Oremland of the United States Geological Survey in Menlo Park, California.

Arsenic (III) is the most poisonous form of the element, because it acts much like phosphorous.

Arsenic can substitute for phosphorous and upset the ATP molecule

arsenic may have been an important nutrient

Photosynthesis may be the most important biochemical machine on the planet.

Nadal poised to become number one

Wimbledon champion Rafael Nadal ensured he will take the world number one spot after reaching the semi-finals of the Cincinnati Masters on Friday.

Federer's run of 235 consecutive weeks at the top of the ATP rankings was put in jeopardy when he was knocked out of the tournament on Thursday by 16th seed Ivo Karlovic.

Anaerobic Exercise

Wed, 02 Jul 2008 16:37:28 GMT

Clip Source: en.wikipedia.org

Anaerobic exercise is exercise intense enough to trigger anaerobic metabolism. It is used by athletes in non-endurance sports to build power and by body builders to build muscle mass. Muscles trained under anaerobic conditions develop differently, leading to greater performance in short duration, high intensity activities, which last up to about 2 minutes.^[1]

Aerobic exercise, on the other hand, includes lower intensity activities performed for longer periods of time. Such activities like walking, running, swimming, and cycling require a great deal of oxygen to generate the energy needed for prolonged exercise to keep you at a certain energy level.

There are two types of anaerobic energy systems, the ATP-CP energy system, which uses creatine phosphate as the main energy source, and the lactic acid (or anaerobic glycolysis) system that uses glucose (or glycogen) in the absence of oxygen.

Is Hoodia a Safe and Effective Supplement?

In a trial of 24 morbidly obese people where all that they could do was to read, watch television, interact with each other, and of course eat. Half the participants were given Hoodia Gordonii, and the other half a placebo. After 15 days the Hoodia Gordonii group had reduced their calorie intake by 1000 calories a day, despite taking no exercise and not being on any kind of weight loss diet.

Whole Hoodia powder contains fiber, antioxidants, and the only reported active ingredient P57, an oxypregnane steroidal glycoside. Studies at Brown University Medical School have demonstrated P57 to be a hypothalamic ATP modulator, increasing the content of ATP by 50-150%. ATP is the molecule that stores the energy that we need for every action that we perform in life. P57 informs the brain that blood glucose levels are high, thus fooling the brain into thinking it’s full. P57 contains zero calories, yet is 10, 000 times more potent than sugar in suppressing appetite.

SET 1

Darcis laat Baghdatis terugkomen van 30-0 tot 30-30. Dan twee punten voor onze landgenoot zodat het 2-2 wordt.

40-0 voor Baghdatis. Darcis pakt nog een puntje terug, maar daar blijft het bij: 2-1.

In zijn eerste opslagspel komt Darcis 0-30 achter, maar dan wint hij vier punten op rij: 1-1.

Baghdatis begint met serveren. De Cyprioot wint zonder problemen zijn opslagspel: 1-0.

VOORAF

Een lastige loting voor Steve Darcis in zijn eerste Wimbledon. Onze landgenoot, nummer 52 van de wereld, krijgt met Marcos Baghdatis een tegenstander voorgeschoteld die al prima resultaten op gras liet noteren. De Cyprioot staat 25ste op de ATP-ranglijst, maar is tiende reekshoofd in Londen. Vorig jaar haalde hij de kwartfinale op Wimbledon.

Paes/Bhupathi Make Winning Start

Second seeds Leander Paes and Mahesh Bhupathi (pictured) advanced to the quarterfinals of the Ordina Open in ‘s-Hertogenbosch after defeating Swiss/Argentine pairing Yves Allegro and Sebastian Prieto 6-3, 7-6(3).

Playing together in an ATP main draw for the first time in four years, the Indian three-time Grand Slam champions hit five aces and managed to convert on one of five break points to win after 1 hr., 11 min. Paes, who celebrated his 35th birthday today, is a two-time former champion at the event, winning in 1999 (w/Siemerink) and 2006 (w/Damm), while the 34-year-old Bhupathi is making his debut.

Sperm-powered Nanobots

The next wave in health care may include a brigade of medical nanobots, devices tiny enough to ride the flow of blood through the body's arteries to a problem area. The bots might arrive at a clot, for example, and then using an internal power system, obliterate the clot with a precisely targeted drug or therapy. Designing a power source to accomplish such a task has been a challenge, but from the College of Veterinary Medicine at Cornell University comes a possible answer. The same molecular power packs that fuel sperm in their journey through the uterus and to a fallopian tube might be copied and used to keep the nanomachines running once they reach their targets.

Ordinarily the ATP provides sperm with enough energy to bend and flex their tails as they swim to the unfertilized egg. Travis’s plan is to copy the design of the sperm’s engine by slightly modifying a 10-enzyme glycolysis chain embedded in the sperm’s tail, and then to install it in nanobots.

Why Does the Brain Need So Much Power?

Wed, 07 May 2008 11:06:21 GMT

Clip Source: www.sciam.com

It is well established that the brain uses more energy than any other human organ, accounting for up to 20 percent of the body's total haul. Until now, most scientists believed that it used the bulk of that energy to fuel electrical impulses that neurons employ to communicate with one another. Turns out, though, that is only part of the story.

A new study in Proceedings of the National Academy of Sciences USA indicates that two thirds of the brain's energy budget is used to help neurons or nerve cells "fire'' or send signals. The remaining third, however, is used for what study co-author Wei Chen, a radiologist at the University of Minnesota Medical School, refers to as "housekeeping," or cell-health maintenance.

Their goal: to determine whether ATP production is linked to brain activity by measuring the energy expended during different levels of consciousness.

Sure enough, ATP levels appeared to vary with brain activity
