THE THEORY OF MECHANISM OF DISEASE

ONE THEORY ON THE MECHANISM OF DISEASE
In recent years scientists have focused their attention on a disease that some attribute to an abnormal form of a protein called a PRION. The theory is that disease results when defective prions bind to normal prion proteins, causing the normal protein to misfold. The result is “a chain reaction that propagates the disease and generates new infectious material” says the journal Scientific American.

What may have been an instance of prion-based disease first came to public attention in the 1950’s in Papua New Guinea. Certain isolated tribes engaged in a form of cannibalism for religious reasons, and this led to a disease called KURU, with symptoms similar to those of Creutzfeldt-Jakob disease. Once the afflicted tribes gave up this religious ritual, the incidence of KURU rapidly declined, and it is now virtually unknown.

                                                         AMAZING DESIGN!

Happily, though, proteins are usually folded correctly and go about their tasks with amazing cooperation, efficiency, and fidelity. This is remarkable considering that there are over 100,000 different kinds of proteins in the human body, all complex chains arranged into thousands of types of folds.

The world of proteins is still largely uncharted. To learn more, researchers are now devising sophisticated computer programs that may predict the shape of proteins from their amino acid sequence. Still, even the little we know about proteins establishes clearly that these “chain of life” not only possess a high level of organization but also reflect a profound intelligence.

PLASTIC SURGERY; PROS AND CONS

-
“Prior to my nose operation, I suffered a lot because of teasing. I did not want a nose that was special, just one that suited me. I am very happy with the result, and I would do same thing all over again.”-Elea.” “Why should I submit to standardized ideas of good looks? With surgically altered body parts. I would feel like fake money. Not genuine.”-Matthew. “Everyone must decide for himself or herself. It is very difficult for someone else to judge.”-Imma “Whoever is prettier than I am must be wearing makeup.” In Germany, that humorous saying has long served as a sort of defense for people who worry that their looks are less than perfect. In some lands nowadays, though, the saying might well be updated to: “Whoever is prettier than I am must have gone under knife.” Indeed, cosmetic surgery is becoming commonplace. “The days are over when cosmetic surgery was reserved for the rich,” reports the Swiss newspaper Neue Zurcher Zeitung, adding: “Two trends have emerged: More and more me

THE HUMAN PERFECT BODY

-
OUR BODY: THE PERFECT MACHINE - When you reflect on the remarkable abilities of various animals, do you sometimes feel a twinge of envy? Perhaps you wish that you could soar like an albatross, swim like a dolphin, see like an eagle, or run like a cheetah. Yes, animals have some amazing abilities. But so do we! Indeed, the human body has been described as the perfect machine. Of course, we are much more than a machine. We have creativity, curiosity, imagination, and ingenuity –qualities that move us to devise machines that enable us to do virtually anything we set our minds to. https://mysticrealityfacts.blogspot.com/2014/12/the-magic-in-your-fingers.html We can fly, even beyond the speed of sound; navigate above or below the surface of vast oceans; gaze some 14 billion light-years into space; peer into the living cell; and design medicines, therapies, and technologies that help us diagnose and treat diseases. Even with little or no external assista

RUSSIAN BLINI

-
RUSSIAN BLINI The French have their CREPES, the Scots their BANNOCK, and the Americans their FLAPJACKS. So it comes as no surprise that Russians have their own version of the PANCAKE –the BLIN, which is a staple with a long history. The ancient Slavs used blini for food sacrifices in their pagan rituals and saw in blini an appropriate symbol of round, warm, golden sun. Women who had recently given birth were fed blini. These were also served at weddings and at funerals, so they figured in peoples’ lives from birth to death. Russians today usually make blini with wheat flour, but other flours can also be used. RECIPE FOR BUCKWHEAT BLINI INGREDIENTS 120 grams buckwheat flour 120 grams wheat flour 20 grams butter, melted 2 eggs 720 milliliters or so of milk 30 grams sugar Pinch of salt PREPARATION: Mix buckwheat flour with 240 milliliters of milk. Heat another 240 milliliters of milk, and add it to the batter,
