Cient\u00edficos brit\u00e1nicos descubrieron en un an\u00e1lisis de laboratorio que la plata es tan efectiva para matar c\u00e9lulas cancerosas como la quimioterapia. Pero a diferencia del f\u00e1rmaco, el metal no provoca los perjudiciales efectos secundarios en el tejido sano del paciente.<\/p>\n
Seg\u00fan los investigadores de las universidades de Leeds y Bradford, Inglaterra, ciertos compuestos espec\u00edficos de la plata podr\u00edan utilizarse para tratar algunos tipos de c\u00e1ncer.<\/p>\n
Todav\u00eda, sin embargo, ser\u00e1 necesario llevar a cabo m\u00e1s estudios para conocer c\u00f3mo act\u00faa el metal en las c\u00e9lulas.<\/p>\n
Toxicidad<\/strong> Este medicamento se usa para tratar varios tipos de c\u00e1ncer, incluido pulmonar, de mama, vejiga, test\u00edculos, cabeza y cuello y ovarios.<\/p>\n Se conoce, sin embargo, que el cisplatin, igual que otros f\u00e1rmacos de quimioterapia, provoca severos efectos secundarios como v\u00f3mito y n\u00e1usea, fallo renal y supresi\u00f3n del sistema inmune.<\/p>\n Por eso muchos equipos cient\u00edficos en todo el mundo est\u00e1n buscando una alternativa que sea igualmente efectiva que la quimioterapia para matar c\u00e9lulas cancerosas pero sin tener efectos perjudiciales en las c\u00e9lulas sanas del paciente.<\/p>\n La doctora Charlotte Willans y su equipo analizaron en el laboratorio diferentes compuestos qu\u00edmicos basados en mol\u00e9culas de plata y los expusieron a c\u00e9lulas cancerosas de mama y colon.<\/p>\n Los cient\u00edficos expusieron las c\u00e9lulas a los compuestos durante per\u00edodos de seis d\u00edas y posteriormente compararon sus efectos con los del Cisplatin. Los resultados aparecen publicados en la revista Dalton Transactions.<\/p>\n *Nota de dailymail.com.uk Silver can kill some cancers as effectively as chemotherapy and with potentially fewer side effects, new research claims. British researchers now say that silver compounds are as effective at killing certain cancer cells as a leading chemotherapy drug, but with potentially far fewer side-effects.<\/p>\n They compared it to Cisplatin, currently used to treat a wide variety of cancers, but known to have harsh side effects including nausea, vomiting and even kidney damage.<\/p>\n Silver is used already in everyday products such as deodorant with no known side-effects, and could make for a potentially cheaper alternative to platinum-based Cisplatin. <\/p>\n Researchers from the University of Leeds conducted lab tests which exposed breast and colon cancer cells to various silver-based chemicals over a six day period. Results, published in journal Dalton Transactions, showed that these silver-compounds were \u2018as effective as Cisplatin\u2019 at killing cancer with potentially fewer side effects.<\/p>\n While the team are still unsure about how exactly silver battles cancer, they think its effectiveness may be caused by the structure surrounding silver atoms, known as its ligand. <\/p>\n They think this may help release the silver ion into cells when it enters the body, killing any cancer.<\/p>\n Study author Dr Charlotte Willans plans to spend the next year looking closely at what effect silver has on both cancerous and healthy cells, and whether it could be a safe and effective new anti-cancer drug. ‘Getting these results also gives us the opportunity we need to apply for funding to take the research further. ‘This could lead to a cheaper, less toxic alternative to current treatments for cancer.’<\/p>\n Explaining the research in greater detail, Dr Willans added: ‘As many are unfortunately aware, chemotherapy can be a very gruelling experience for the patient.<\/p>\n ‘Finding effective, yet non-toxic drugs is an ongoing problem, but these preliminary results are an important step in solving it.<\/p>\n ‘Our research has looked at the structure which surrounds a central silver atom. This \u00abshrubbery\u00bb is what determines how reactive it is and what it will interact with.’Our research has used different types of these ligands to see which is the most effective against cancer cells.’<\/p>\n","protected":false},"excerpt":{"rendered":" Cient\u00edficos brit\u00e1nicos descubrieron en un an\u00e1lisis de laboratorio que la plata es tan efectiva para matar c\u00e9lulas cancerosas como la quimioterapia.

\nActualmente, uno de los principales f\u00e1rmacos de quimioterapia contra el c\u00e1ncer, el cisplatin, est\u00e1 basado en compuestos de platino.<\/p>\n
\nSilver bullet for cancer: Metal can kill some tumours better than chemotherapy with fewer side effects<\/p>\n
\nScientists say that old wives tales about the precious metal being a \u2018silver bullet\u2019 to beat the Big C could be true.
\nThe metal already has a wide range of medicinal uses and is a common antiseptic, antibiotic and means of purifying water in the third world. <\/p>\n
\nShe said: ‘It\u2019s certainly an exciting discovery, although I think we have a lot of work to do in the future. It opens the doors in terms of what we can do and investigate.<\/p>\n
