El trasplante de células embrionarias regenera parcialmente el sistema nervioso de ratas

La combinación de distintas terapias, incluido el injerto de células madre obtenidas de embriones de roedores, permite restaurar parcialmente el sistema nervioso de ratas paralíticas. Así lo asegura un nuevo estudio recibido por los especialistas con satisfacción pero con prudencia.

El trabajo, publicado en 'Annals of Neurology' y dirigido por Douglas Kerr, de la Facultad de Medicina de la Universidad Johns Hopkins (EEUU), es el primero que muestra que el trasplante de neuronas, obtenidas de células embrionarias, puede formar conexiones funcionales con el sistema nervioso de un mamífero adulto, según los investigadores.

En el estudio, ratas paralíticas tratadas con una combinación de varias terapias pudieron recuperar parcialmente el movimiento de sus patas traseras.

Curiosamente, vi essa notícia num canal de tv por cabo cá da terra, e fiquei, que diria contente. Há alguns meses tinha lido a propósito de células estaminais na National Geographic, sobre o efeito sque estas poderiam ter no tratamento de doenças/lesões graves. Felizmente o prognóstico vai-se confirmando.

Stephen Halliwell GREEK LAUGHTER A study of cultural psychology from Homer to early Christianity In the third century BC, when Roman ambassadors were negotiating with the Greek city of Tarentum, an ill-judged laugh put paid to any hope of peace. Ancient writers disagree about the exact cause of the mirth, but they agree that Greek laughter was the final straw in driving the Romans to war. One account points the finger at the bad Greek of the leading Roman ambassador, Postumius. It was so ungrammatical and strangely accented that the Tarentines could not conceal their amusement. The historian Dio Cassius, by contrast, laid the blame on the Romans’ national dress. “So far from receiving them decently”, he wrote, “the Tarentines laughed at the Roman toga among other things. It was the city garb, which we use in the Forum. And the envoys had put this on, whether to make a suitably dignified impression or out of fear – thinking that it would make the Tarentines respect them. But in fact g...

The Pill, a short history

Imagem
( this in Britain ) It was the first lifestyle drug, launched against fierce opposition from the moral right, which revolutionised social and sexual attitudes and helped define the 1960s. Now, almost 50 years on, it is to be made available over the counter without a prescription. Another milestone in the history of the contraceptive pill was signalled last week with the disclosure that, from the New Year, pilot schemes in two south-London primary care trusts, Southwark and Lambeth, will, for the first time, allow pharmacists and nurses to provide it to women over the age of 16. The aim is to test whether making the Pill more easily accessible reduces unwanted pregnancies. Pharmacies are open for longer hours than GP surgeries and do not require an appointment or have long waits. The Family Planning Association said that it received scores of calls from women who had run out of the Pill and didn't know where to go to rep...
