Clonación de células embrionales humanas
Human Embryonic Stem Cells Derived by Somatic Cell Nuclear Transfer
Aquí les facilito el "abstract" de una investigación fundamental llevada a cabo por un nutrido grupo de estudiosos. Hasta ahora todos los intentos de clonar células humanas habían sido infructuosos. De modo muy siplificado lo que hacen los científicos es reprogramar células ya diferenciadas, es decir somáticas, con una determinada función, en células pluripotenciales, aptas para asumir nuevas funciones. La técnica pasa por la transferencia nuclear (ver esquema). Es un paso significativo para lograr terapias individuales (el paciente recibe sus propias células). Esperemos que una correcta información a los ciudadanos/as conjure los fantasmas retrógrados que ven una amenaza en cualquier avance científico. El presente experimento no va contra la dignidad del ser humano. Ni vulnera su integridad.Masahito Tachibana1, Paula Amato2, Michelle Sparman1, Nuria Marti Gutierrez1, Rebecca Tippner-Hedges1, Hong Ma1, Eunju Kang1, Alimujiang Fulati1, Hyo-Sang Lee1, 6, Hathaitip Sritanaudomchai3, Keith Masterson2, Janine Larson2, Deborah Eaton2, Karen Sadler-Fredd2, David Battaglia2, David Lee2, Diana Wu2, Jeffrey Jensen1, 4, Phillip Patton2, Sumita Gokhale5, Richard L.

Summary
- Reprogramming somatic cells into pluripotent embryonic stem cells (ESCs) by somatic cell nuclear transfer (SCNT) has been envisioned as an approach for generating patient-matched nuclear transfer (NT)-ESCs for studies of disease mechanisms and for developing specific therapies. Past attempts to produce human NT-ESCs have failed secondary to early embryonic arrest of SCNT embryos. Here, we identified premature exit from meiosis in human oocytes and suboptimal activation as key factors that are responsible for these outcomes. Optimized SCNT approaches designed to circumvent these limitations allowed derivation of human NT-ESCs. When applied to premium quality human oocytes, NT-ESC lines were derived from as few as two oocytes. NT-ESCs displayed normal diploid karyotypes and inherited their nuclear genome exclusively from parental somatic cells. Gene expression and differentiation profiles in human NT-ESCs were similar to embryo-derived ESCs, suggesting efficient reprogramming of somatic cells to a pluripotent state.

Sabiduría psicópata
El problema es que,
en opinión del psicólogo Kevin Dutton,
autor de los libros “Split-second persuasión” y “The wisdom
of psychopaths”, los rasgos psicopáticos pueden aparecer en
distinto grado en cada individuo. Y es el nivel y la combinación de
los que se presentan lo que determina si se trata o no de una
psicopatía patológica.
“Los psicópatas carecen
de miedo, están seguros de si mismos, son carismáticos, despiadados
y centrados. Pero, en contra de la creencia popular, no
necesariamente violentos”, explica Dutton, psicólogo investigador
en el Centro de Investigación Calleva para la Evolución y las
Ciencias Humanas del Colegio Magdalen, en Oxford.
Al parecer los
atributos psicopáticos pueden ser de utilidad a la hora de
desempeñar determinadas profesiones. Y Dutton menciona el caso del
neurocirujano al que designaremos como GX, un reconocido profesional del Reino
Unido cuyas palabras tal vez provoquen escalofríos: “”No tengo
compasión por aquellos a los que opero. Es un lujo que no me puedo
permitir. En el quirófano renazco como una máquina fría y sin
corazón, totalmente aunado con el bisturí, taladro y la sierra.
Cuando te dejas llevar y burlas a la muerte en los confines del
cerebro, los sentimientos no sirven para nada. La emoción es
entropía y no sirve para el negocio. Le he dado caza hasta
conseguir extinguirla con los años”.
La verdad es que lo
comprendo bien. Me he subido a una moto de gran
cilindrada y viajado a velocidades vertiginosas. Nunca lo hubiera hecho de no
ser el conductor un experto, pero además un sujeto muy frío, que desconoce el miedo, con
gran capacidad de concentración y bastante poco empático.
El asunto es complejo, como todo lo que tiene que ver con las neurociencias y se ha comenzado a estudiar
vinculado al cerebro físico. Resulta, y es una simplificación, que
el cerebro “normal” demuestra actividad en ciertas zonas cuando se
somete al sujeto a una disyuntiva moral. Esa misma resonancia
magnética funcional en el psicópata arroja una oscuridad
sintomática de que allí no ocurre nada.
Puestos a
discriminar, algunos atributos psicopáticos aparecen con mayor
frecuencia en líderes empresariales antes que en los perturbados
criminales. Por ejemplo los distantes y calculadores financieros pueden
ser superficialmente encantadores, al tiempo que egocéntricos,
persuasivos y ojo, carentes de empatía.

Guantánamo ya ha fracasado
Death is Preferable to Life at Obama’s Guantanamo
By Marjorie Cohn
Marjorie Cohn is a professor at Thomas Jefferson School of Law and former president of the National Lawyers Guild. Her most recent book is The United States and Torture: Interrogation, Incarceration, and Abuse. See www.marjoriecohn.com.

El centro de detención militar establecido por Estados Unidos en la base naval de Guantánamo (Cuba) para intentar combatir el terrorismo islámico es un fracaso prolongado. Eso es lo que parece deducirse de las exiguas informaciones obtenidas de reclusos que llevan allí años en condiciones cuando menos de dudosa legalidad. Ni las torturas cotidianas, ni el aislamiento han doblegado a hombres que, con toda probabilidad, se blindan en sus creencias religiosas.
El presidente Obama expresó sus buenas intenciones de clausurar Guantánamo. En la práctica el asunto se le ha ido de las manos. Luchar contra el terrorismo islámico es una tarea muy difícil.
Me viene a la memoria una novela de Frederik Forsyth titulada "El afgano", en la que un oficial de inteligencia británico suplanta a un fiero dirigente yihaidista a fin de conocer los planes de ciertos grupos implicados en lo que puede ser un gran atentado. La trama, apasionante, ayuda a situarse en la variopinta estructura del presunto enemigo: clanes, tribus, familias, por encima de ejércitos convencionales o de guerrillas. Multitud de lenguas, variaciones dialectales, y usos y costumbres diferentes. Se me ocurre, desde mi profunda ignorancia, que la mejor manera de combatirlos es con muchísima inteligencia. El artículo de Cohn pone en contexto el asunto.

More than 100 of the 166 detainees at Guantanamo are starving themselves to death. Twenty-three of them are being force-fed. “They strap you to a chair, tie up your wrists, your legs, your forehead and tightly around the waist,” Fayiz Al-Kandari told his lawyer, Lt. Col. Barry Wingard. Al-Kandari, a Kuwaiti held at Guantanamo for 11 years, has never been charged with a crime. “The tube makes his eyes water excessively and blood begins to trickle from the nose. Once the tube passes his throat the gag reflex kicks in. Warm liquid is poured into the body for 45 minutes to two hours. He feels like his body is going to convulse and often vomits,” Wingard added.
The United Nations Human Rights Council concluded that force-feeding amounts to torture. The American Medical Association says that force-feeding violates medical ethics. “Every competent patient has the right to refuse medical intervention, including life-sustaining interventions,” AMA President Jeremy Lazarus wrote to Defense Secretary Chuck Hagel. Yet President Barack Obama continues the tortuous Bush policy of force-feeding hunger strikers.
Although a few days after his first inauguration, Obama promised to shutter Guantanamo, it remains open. “I continue to believe that we’ve got to close Guantanamo,” Obama declared in his April 30 press conference. But, he added, “Congress determined that they would not let us close it.” Obama signed a bill that Congress passed which erected barriers to closure. According to a Los Angeles Times editorial, “Obama has refused to expend political capital on closing Guantanamo. Rather than veto the defense authorization bills that have limited his ability to transfer inmates, he has signed them while raising questions about whether they intruded on his constitutional authority.”
“I don’t want these individuals to die,” Obama told reporters. In fact, Obama has the power to save the hunger strikers’ lives without torturing them. Eighty-six – more than half – of the detainees remaining at Guantanamo have been cleared for release for the past three years. Section 1028(d) of the 2013 National Defense Authorization Act empowers the Secretary of Defense to approve transfers of detainees when it is in the national security interest of the United States. Fifty-six of the 86 cleared detainees are from Yemen. Yet Obama imposed a ban on releasing any of them following the foiled 2009 Christmas bomb plot by a Nigerian man who was recruited in Yemen. Obama must begin signing these certifications and waivers at once.
Indeed, Obama said in his press conference, “I think – well, you know, I think it is critical for us to understand that Guantanamo is not necessary to keep America safe . . . It hurts us in terms of our international standing . . . It is a recruitment tool for extremists. It needs to be closed.”
In addition, Obama’s March 7, 2011 Executive Order 13567 provides for additional administrative review of detainees’ cases. The Periodic Review Board (PRB) would provide an opportunity for a detainee to challenge his continued detention. Yet Obama has delayed by more than a year PRB hearings at which other detainees could be cleared for release. Despite a requirement that the PRB begin review within one year, no PRB has yet been created. Obama should appoint an official to oversee the closure of Guantanamo and commence periodic reviews immediately so that detainees can challenge their designations and additional detainees can be approved for transfer.
Moreover, as suggested by Lt. Col. David Frakt, who represented Guantanamo detainees before the military commissions and in federal habeas corpus proceedings, Obama should direct the attorney general to inform the D.C. Circuit Court of Appeals that the Department of Justice no longer considers the cleared detainees to be detainable. Obama has blocked the release of eight cleared detainees by opposing their habeas corpus petitions. “[W]hen the Obama administration really wants to transfer a detainee, they are quite capable of doing so,” Frakt wrote in Jurist.
The Constitution Project’s Task Force on Detainee Treatment, which includes two former senior U.S. generals, and a Republican former congressman and lawyer, Asa Hutchinson, issued a report that concluded the treatment and indefinite detention of the Guantanamo detainees is “abhorrent and intolerable.” It called for the closure of the prison camp by next year.
Twenty-five former Guantanamo detainees issued a statement recommending that the American medical profession stop its complicity with abuse force-feeding techniques; conditions on confinement for detainees be improved immediately; all detainees who have not been charged be released; and the military commissions process be ended and all those be charged tried in line with the Geneva Conventions.
The detainees who are refusing food have been stripped of all possessions, including a sleeping mat and soap, and are made to sleep on concrete floors in freezing solitary cells. “It is possible that I may die in here,” said Shaker Aamer through his lawyer, Clive Stafford Smith. “I hope not, but if I do die, please tell my children that I loved them above all else, but that I had to stand up for the principle that they cannot just keep holding people without a trial, especially when they have been cleared for release.” Aamer, a British father of four, was approved for release more than five years ago.
Col. Morris Davis, who served as Chief Prosecutor for the Terrorism Trials at Guantanamo, personally charged Osama bin Laden’s driver Salim Hamdan, Australian David Hicks, and Canadian teen Omar Khadr. All three were convicted and have been released from Guantanamo. “There is something fundamentally wrong with a system where not being charged with a war crime keeps you locked away indefinitely and a war crime conviction is your ticket home,” Davis wrote to Obama.

Gimnasia anticrisis
| Aquí les dejo a mis visitantes una propuesta para realizar unos 7 minutos de ejercicios. Iba a escribir sobre el día de Europa, que la verdad no le importa a nadie una chaise, sobre el parón de Tribunal Constitucional a la propuesta soberanista catalana (derecho a decidir), pero al final he decidido incluir algo fresquito contra el mal rollo imperante. Por si les interesa, existe una "Liga de los Optimistas", con profesores estadounidenses, empresarios de postín, y señoras cultas que sueltan trolas sobre la "felicidad del consumidor", y la necesidad y oportunidad del pensamiento positivo en medio de la crisis. Vamos, son gente muy del sistema tan bueno y perfecto en que vivimos (el mejor de los mundos, sin dudas). Si usted es un parado/a de larga duración, tipo alimento verdoso caducado, ellos serán "empáticos" con su caso, pero a renglón seguido le recomendarán que mueva el esqueleto, y se busque la vida, eso sí, siempre sonriendo. Y si va a pedir un crédito al banco, pues que acuda con una avalancha de buenas vibraciones que aseguran, se transmitirán al gestor de la entidad financiera, quien le propinará la patada en el trasero, pero con amabilidad. Bueno, hoy en España hay huelga en la educación para padres, maestros y chavales. Mejor practiquen los ejercicios mínimos que he pirateado para vuestras mercedes a mi querido NYT. |

Exploración del genoma fetal
Ya existe un procedimiento no invasivo que podría detectar miles de dolencias en el genoma de los fetos. Se puede obtener el retrato genético de un feto (su genoma completo) utilizando una muestra de sangre de la madre. Sin necesidad de tomar líquido amniótico. Se abre así un camino para detectar de forma segura trastornos que dependen de un solo gen (fibrosis quística, enfermedad de Tay-Sachs o síndrome del cromosoma X frágil). Un diagnóstico más que precoz que permite tomar decisiones: los médicos pueden aplicar un tratamiento en caso que exista, o se puede valorar una interrupción del embarazo si así lo deciden los futuros padres ante una malformación incurable. Pero hay que resaltar que gracias al cribado pueden abordarse tratamientos correctores.
