The blood that is shed during menstruation by women can become a good source of stem cells that can be used to create numerous types of human cells. Scientists managed to grow nine different types of cells, including heart, liver and lung cells. picked by maxriter 11 months ago

Scientists have used embryonic stem cells to generate blood -- a feat that could eventually lead to endless supplies of type O-negative blood, a rare blood type prized by doctors for its versatility picked by bernardblack 2 months ago

For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo. This means it might be possible in the future to produce hESC lines at an earlier stage without destroying the embryo. picked by AutumnLotus 3 months ago

Stem cell researchers at UCLA were able to grow functioning cardiac cells using mouse skin cells that had been reprogrammed into cells with the same unlimited properties as embryonic stem cells. picked by AutumnLotus 5 months ago

The Human Genome Project revealed that only a small fraction of the 3 billion “letter” DNA code actually instructs cells to manufacture proteins, the workhorses of most life processes. This has raised the question of what the remaining part of the human genome does. How much of the rest performs other biological functions, and how much is merely residue of prior genetic events?

A highly sensitive microchip may help doctors detect rare traces of cancer circulating in the bloodstream.The device can isolate, count and analyze circulating tumor cells from a blood sample. These circulating tumor cells, or CTCs, are the tiniest fragments of tumors, which are carried in the blood. picked by 2manyusernames 10 months ago

Menstrual blood can be used to repair heart damage, Japanese researchers said today. Scientists obtained menstrual blood from nine women and cultivated it for about a month, focusing on a kind of cell that can act like stem cells. Some 20 per cent of the cells began beating spontaneously about three days after being put together in vitro with cells from the hearts of rats. picked by AutumnLotus 6 months ago

By blocking the action of angiotensin-converting enzyme (ACE) in mice, Australian researchers have influenced the behaviour of fat cells, causing the rodents to lose weight while simultaneously reducing blood pressure and reducing the risk of diabetes.

Human age is a simulation game / free virtual management game / rpg where you adopt a human being and help him or her through various ages of mankind, from prehistory to the 21st century, from learning how to use a club to your driver's license. picked by daftgretel 1 year ago

Blood donors typically get juice, a cookie and a thank you, but the local Red Cross has parked a new car outside a hospital to entice more people to help ease a blood shortage. The pearl white 2007 Lincoln MKX crossover vehicle has a sign that reads: "Win this car. Give Blood." picked by AutumnLotus 1 year ago

A toddler has had pioneering surgery to stop his heart pumping blood the wrong way around his body.

Alec Hutchinson, three, was born with a rare condition which meant the blood vessels in his heart were plumbed in back to front. picked by AutumnLotus 7 months ago

Scientists have developed an artificial plastic blood which could act as a substitute in emergencies.

Human-animal embryos(created by transferring the nuclei of human cells, such as skin cells, into animal eggs from which almost all the genetic information has been removed) are to be created in the UK after scientists today won approval for the practice from the fertility and embryo research watchdog...

One day soon patients may spit in a cup, instead of bracing for a needle prick, when being tested for cancer, heart disease or diabetes. A major step in that direction is the cataloging of the “complete” salivary proteome, a set of proteins in human ductal saliva. Replacing blood draws with saliva tests promises to make disease diagnosis, as well as the tracking of treatment efficacy, ... read full post picked by 2manyusernames 7 months ago

Scientists at the University of Bonn have discovered a new rare type of haemoglobin. The new haemoglobin type appears optically to be transporting little oxygen. Measurements of the blood oxygen level therefore present a similar picture to patients suffering from an inherited cardiac defect. After examining two patients, the scientists now understand that the new type of haemoglobin distorts the l... read full post picked by AutumnLotus 7 months ago

While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage. A group of scientists has investigated this less-studied idea, carrying out the first systematic computational analysis to identify long-established genes that have been lost across millions of years of evolution leading to the human species. picked by AutumnLotus 10 months ago
