Yondelis . Advances in Multidisciplinary Therapy for Meningiomas.

Neuro-Oncology, Volume 21, Issue Supplement_1, 14 January 2019, Pages i18–i31 .

Surgery has long been established as the first-line treatment for the majority of symptomatic and enlarging meningiomas, and evidence for its success is derived from retrospective case series.


 Despite surgical resection, a subset of meningiomas display aggressive behavior with early recurrences that are difficult to treat. 

The decision to radically resect meningiomas and involved structures is balanced against the risk for neurological injury in patients. 

Radiation therapy has largely been used as a complementary and safe therapeutic strategy in meningiomas with evidence primarily stemming from retrospective, single-institution reports. 

Two of the first cooperative group studies (RTOG 0539 and EORTC 22042) evaluating the outcomes of adjuvant radiation therapy in higher-risk meningiomas have shown promising preliminary results.

 Historically, systemic therapy has resulted in disappointing results in meningiomas. 

However, several clinical trials are under way evaluating the efficacy of chemotherapies, such as Trabectedin, and Novel molecular agents targeting Smoothened, AKT1, and focal adhesion kinase in patients with Recurrent Meningiomas.

Concise total syntheses of (–)-jorunnamycin A and (–)-jorumycin enabled by asymmetric catalysis .

Journey to Jorumycin.

Jorumycin is a structurally complex, pentacyclic organic compound produced by a marine mollusk. The success of a similar compound, trabectedin, in treating certain types of cancer has focused attention on exploring jorumycin's pharmaceutical properties. Welin et al. developed a succinct route to synthesizing jorumycin and the closely related jorunnamycin A that deliberately diverges from the putative biosynthetic pathway underlying prior chemical syntheses. This route, which hinges on a carefully optimized asymmetric catalytic hydrogenation, can be easily modified to introduce unnatural structural diversity for functional optimization in further drug discovery research.

¿Los tickets de la compra causan cáncer? .

Este miércoles se hizo público un estudio que afirma que los tickets de la compra en los que la tinta se borra pueden causar infertilidad y cáncer. Esta es la afirmación de un grupo de investigadores de la Universidad de Granada, que recomienda «no jugar con estos tickets, ni arrugarlos para tirarlos, escribir notas o guardarlos en el coche, el monedero o el bolso». ...
