Question: Somewhere in harbourside Sydney, Australia, a family lives within a high-rise apartment building where the mother is preparing a meal and listening to the radio. Her fourteen year old daughter (Jenny Agutter) and six year old son (Luc Roeg) swim in the building's pool overlooking a view of the ocean while their father (John Meillon), deep in troubled thought, watches them from their balcony.One day, the father takes his children, still in their school uniforms, on a picnic into the Outback. He parks the car and reads while his daughter sets up a blanket with their lunch. Her brother plays nearby with his water gun and toy soldiers. Suddenly, and for reasons unclear to his children, the father announces it is time to go and brandishes a gun, firing several shots at them. The boy thinks it all to be a game but his sister understands the danger and shields her brother as they run from their mad father. She watches in horror as her father returns to the car and sets it on fire before seating himself within and putting a bullet into his head. Quickly, and keeping her brother's eyes averted, the girl retrieves their radio, a scarf, and what food she can carry before setting off into the wilderness with her brother.The siblings walk for hours under the hot sun, calmed by irrelevant radio broadcasts, and walking past a host of wild creatures. Come nightfall, they make a crude camp for themselves, much to the boy's delight. In the morning, the girl leads them up a rocky hillside where she hopes to find some bearings. However, she can see nothing but a broad spanse of wilderness. When they finish their lemonade, the girl opens a can of vegetables from which they drink the juice. Recalling an uncle's story of military training, the girl suggests they eat salt to retain water and surmises to her brother that they may spend some time in the desert. She remains stoic, but wary, while her brother is blissfully unaware of their situation, remaining entertained by the radio and his toys. Eventually, after becoming filthy and tired, they come upon a lone tree standing over a pool of water where parakeets flock and feast on fallen fruit. The boy puts on in his mouth and proclaims that it 'tastes lovely'. They wash in the water and the girl scolds her brother to take care of his clothes so they will last. When he asks if they are lost, the girl replies that they are not, trying to remain chipper. They sleep to the sounds of the radio as night animals stir around them.In the morning, the girl wakes to find that their water hole has dried up and the fruit has either been eaten or spoiled. The girl decides to remain where they are, hoping that the water will return. As they nap in the hot sun, the boy spots an aborigine youth (David Gulpilil) pursuing an animal for food. They make contact and the children attempt to communicate with the aborigine boy. However, he does not understand their language and merely stares at them with curiosity. The girl repeats their need for water but the word is incomprehensible to the aborigine. When her brother mimics drinking, the aborigine understands and shows them how to dig for water using a hollow tube to drink through. Assuming that he will lead them to civilization, the siblings accompany the aborigine, unaware that he is on a 'walkabout', a coming-of-age journey that every male aborigine youth must take alone in order to be initiated as an adult in his tribe.As they travel the Outback, the aborigine kills and harvests food for them, giving them all plenty to eat and drink. The move from the desert to greener pastures and forests where wildlife becomes plentiful. When the boy becomes sunburnt from going shirtless, the aborigine rubs pig fat on his back to alleviate the burn. While communication between them remains limited, the trio share food and play together, though cultural differences are evident; the boy attempts to share his toy soldiers with the aborigine, but he finds no use for them and tosses

Answer: What does the Aboriginal boy hunt down ?


Question: Young people frequently say that they want to exercise, but they just can't find the time. The solution just might be in-office interval training. Recent studies show that very short but intense exercise rapidly builds and maintains fitness and health, even when the workout is only a few minutes long. Work the stairs You can complete an excellent, effective -- and very brief -- workout in an office stairwell, says Martin Gibala, a professor of kinesiology at McMaster University in Canada and an expert on interval training. For a study that he and his colleagues presented earlier this year, they asked 12 out-of-shape women in their 20s to warm up for two minutes by slowly walking up and down stairs in a campus office building. They completed three of these abbreviated stair workouts per week for six weeks. By the end, their aerobic fitness had improved substantially, the researchers reported, by about as much as if they had been running or cycling each week for hours. Fidget your way to fitness. Parents and teachers may once have urged you to sit still, but wiggling, tapping your toes, standing briefly, and otherwise fidgeting as much as possible at your desk is in fact good for your body. In one recent study, college students showed healthier blood flow in their lower legs if they fidgeted than if they did not. Even better, a 2008 study found that among office workers, those who frequently fidgeted burned as many as 300 calories more each day than those who resolutely stayed still.

Question: Interleukin-1 (IL-1) is a proinflammatory cytokine that is implicated in many autoinflammatory disorders, but is also important in defense against pathogens. Thus, there is a need to safely and effectively modulate IL-1 activity to reduce pathology while maintaining function. Gevokizumab is a potent anti-IL-1 antibody being developed as a treatment for diseases in which IL-1 has been associated with pathogenesis. Previous data indicated that gevokizumab negatively modulates IL-1 signaling through an allosteric mechanism. Because IL-1 signaling is a complex, dynamic process involving multiple components, it is important to understand the kinetics of IL-1 signaling and the impact of gevokizumab on this process. In the present study, we measured the impact of gevokizumab on the IL-1 system using Schild analysis and surface plasmon resonance studies, both of which demonstrated that gevokizumab decreases the binding affinity of IL-1 for the IL-1 receptor type I (IL-1RI) signaling receptor, but not the IL-1 counter-regulatory decoy receptor (IL-1 receptor type II). Gevokizumab inhibits both the binding of IL-1 to IL-1RI and the subsequent recruitment of IL-1 accessory protein primarily by reducing the association rates of these interactions. Based on this information and recently published structural data, we propose that gevokizumab decreases the association rate for binding of IL-1 to its receptor by altering the electrostatic surface potential of IL-1, thus reducing the contribution of electrostatic steering to the rapid association rate. These data indicate, therefore, that gevokizumab is a unique inhibitor of IL-1 signaling that may offer an alternative to current therapies for IL-1-associated autoinflammatory diseases.
