...evocatively grotesque, notably in the instance of the diseased mendicants on the streets of Nairobi; “Most were maimed. Lepers with truncated arms and legs were a common sight; but even more numerous than the lepers were victims of severe bone malformation, the result of calcium deficiency. This affliction ravages the human frame, reducing it to tangled wreckage of atrophied limbs.”The prose is not merely precise but elegant and memorable, full of acerbic wit and unusual metaphor. The writing illuminates not only the landscape and the people in general, but also a succession...
Floating around in space isn't as relaxing as it might sound. Astronauts expend a lot of energy and endure extreme stresses on their bodies. Their dietary requirements are therefore different from those of their gravity-bound counterparts on Earth. For example, they need extra calcium to compensate for bone loss. (Bones tend to regenerate slower in space, and the loss of mass begins almost immediately after takeoff). A low-sodium diet helps slow the process, but according to Kloeris, that's easier said than done. "There are no refrigerators in space, and salt is often used to help preserve...
...girls (why that's so is still not clear), and the authors suggest it plays a role in boys' increased risk of the developmental disorder. CACNA1G, which sits on chromosome 17, amid other genes that have been previously linked to autism, is responsible for regulating the flow of calcium into and out of cells. Nerve cells in the brain rely on calcium to become activated, and research suggests that imbalances in the mineral can result in the overstimulation of neural connections and create developmental problems, such as autism and even epilepsy, which is also a common feature of autism...
...dangerous to demonize dairy, which is absolutely essential for our health. You cannot replace it with vegetables or soya. The French board for nutrition and health advises the consumption of three helpings of dairy products a day, and four for children, adolescents and the elderly. Indeed, dairy contains the calcium, proteins and vitamin D our body needs, especially at certain times of life. It is dangerous to make people believe that they can do without them, for the specious reason that it could hurt the planet. Anne-Sarah Bouglé, BAYEUX, FRANCE
...reaching effects of the disease as well as possible therapeutic targets. Astrocytes are star-shaped cells that make up almost half the volume of the brain, and were traditionally thought to be support cells. It is now known that they can transmit signals through transient increases in calcium levels. “Astrocytes are often thought to play second fiddle to neurons but they play an ever increasing role in maintenance of the brain,” said Brian J. Bacskai, an associate professor of neurology at Harvard Medical School and one of the authors of the study. The researchers...
