Un grupo integrado por científicos de Brasil y del Reino Unido se encuentra abocado a la búsqueda de maneras de aumentar la durabilidad del baipás, el procedimiento quirúrgico que consiste en utilizar parte de una vena de la pierna para efectuar la revascularización del corazón cuando el mismo padece una merma del flujo sanguíneo, una condición que puede llevar al infarto de no tratársela. Una de las claves para evitar que la vena [...]

Electric eels are naked-back knifefishes (Gymnotidae) and are more closely related to catfish and carp than to other eel families. The study, published in Nature Communications, not only provides new knowledge about the animal more than 250 years after it was first described but also opens up new avenues of research into the origin and production of strong electric discharges in other fish species. Gymnotiformes, the knifefish family to which Gymnotidae belong, are native to Mexico and South [...]

An international group of researchers has proven that a molecule called TCMDC-135051 can selectively inhibit a protein that is essential to the lifecycle of Plasmodium falciparum, one of the parasites that causes malaria. The results of the study, just published in the journal Science, pave the way for the development of a new antimalarial drug. Malaria kills nearly 500,000 people per year, and more than 200 million new cases of the disease are reported annually. One of the obstacles to [...]

Oxide plays a key role in cardiovascular and neurodegenerative diseases as well as cancer; experiments reveal a hitherto unknown mechanism underlying the formation of nitroso thiols Ever since three US-based researchers working independently unveiled the role of nitric oxide in mediating blood vessel dilation, endothelial cell contraction and smooth muscle relaxation, their discoveries have served as a basis for novel treatments for high blood pressure and erectile dysfunction, among other [...]
