ABSTRACT
In recent years, the use of stem cells for therapeutic purposes has received attention from research groups. In Mexico, the Mexican Official Standard 260-SSAI-2015 regarding the use of stem and progenitor cells for therapeutic and research purposes is in the process of authorization. Even when this has not been approved, an increasing number of establishments are offering medical services involving the use of stem cells for therapeutic purposes without official regulatory authorization. The Mexican Academy of Medicine of Mexico makes its position public in favor of regulating the use of stem cells and embryos for therapeutic and research purposes.
En años recientes, el uso de células troncales con fines terapéuticos ha recibido atención por grupos de investigación. En México está en proceso de autorización la Norma oficial mexicana 260-SSAI-2015, para la disposición de células troncales y progenitoras con fines terapéuticos y de investigación. Aun cuando esta no ha sido aprobada, cada vez más establecimientos ofrecen servicios médicos con la finalidad de usar células madres con fines terapéuticos sin contar con las autorizaciones sanitarias oficiales. La Academia Nacional de Medicina de México da a conocer su posición acerca de la regulación sobre el uso de células troncales y embriones para fines terapéuticos o de investigación.

In Mexico there is a proliferation of "centers for aesthetic medicine" that offer different treatments with laser beam, mesotherapy and hyaluronic acid and botulinum toxin injections. In numerous centers of this type, offered and performed by medical personnel that are neither trained or certified to ensure the quality of services. The National Academy of Medicine of Mexico and the National Normative Council for Medical Specialties (CONACEM) communicate their posture on this matter.
En México existe una proliferación de "centros de medicina estética" que ofrecen tratamientos diversos con rayos láser, mesoterapia, ácido hialurónico e inyecciones con toxina botulínica por personal médico que no está capacitado ni certificado para asegurar la calidad de los servicios. La Academia Nacional de Medicina y el Comité Normativo Nacional de Consejos de Especialidades Médicas (CONACEM) comunican su postura al respecto.

There are decisions at the end of life that currently are relevant as humanistic values. Respect for human life and dignity are part of human rights. The National Academy of Medicine of Mexico declares its posture about end-of-life decisions that include treatment refusal, limitation of the therapeutic effort, advance directives and palliative sedation, among others, with the purpose to favor a peaceful death.
Hay decisiones relacionadas con el final de la vida que actualmente son relevantes como valores humanísticos. El respeto y la dignidad de la vida humana están incluidos en los derechos humanos. La Academia Nacional de Medicina de México declara su postura acerca de las decisiones sobre el final de la vida que incluyen rechazo a un tratamiento, limitación del esfuerzo terapéutico, voluntad anticipada y sedación paliativa, entre otros, con la finalidad de propiciar una muerte en paz.

Ligands for the NKG2D stimulatory receptor are frequently upregulated on tumor lines, rendering them sensitive to natural killer (NK) cells, but the role of NKG2D in tumor surveillance has not been addressed in spontaneous cancer models. Here, we provided the first characterization of NKG2D-deficient mice, including evidence that NKG2D was not necessary for NK cell development but was critical for immunosurveillance of epithelial and lymphoid malignancies in two transgenic models of de novo tumorigenesis. In both models, we detected NKG2D ligands on the tumor cell surface ex vivo, providing needed evidence for ligand expression by primary tumors. In a prostate cancer model, aggressive tumors arising in NKG2D-deficient mice expressed higher amounts of NKG2D ligands than did similar tumors in wild-type mice, suggesting an NKG2D-dependent immunoediting of tumors in this model. These findings provide important genetic evidence for surveillance of primary tumors by an NK receptor.
