Every few months, it seems like there's a new threat in the media -- some new illness that's killing us. It wreaks havoc on our peace and raises our stress levels! Many parents wonder what specific steps they should take to avoid this one. But the truth is, if we take matters into our own hands and learn to support our immune systems everyday, we don't have to be afraid of everything that comes. We know we're already doing our best, and our families can stay healthy. This guide walks you through exactly how to do that, and how to use research and smart decisions to erase the fear that is so pervasive in the mainstream. In here, you'll find: Why you don't need to be terrified of monkeypox, COVID, polio, or other illnesses in the news Germ theory VS terrain theory What hurts your immune system How to support your immune system properly How and why detox plays a role in health The Immunity Tool Guide has 125 pages and 300+ citations -- giving you a place to start, options to do your own research, and peace of mind that you can take care of your family no matter what comes along. *Please note that this guide is a PDF digital download and not a printed book.
The Spaceillus News August 13, 2016 By Farhana Bajunid What happen to Ebola now? Image from: http://www.janssen.com/sites/www_janssen_com/files/multimedia/ebola_virus.jpg -Ebola virus Ebola outbreak has been confirmed causing 11,315 death from the disease in six countries; Liberia, Guinea, Sierra Leone, Nigeria, the US and Mali. An original outbreak of Ebola virus disease that begun in West Africa in December 2013 has caused many tragic deaths due to sporadic transmission causing infected people to have symptoms of Ebola haemorrhagic fever. This fever is a rare and deadly disease caused by infection with one of the Ebola virus species in the family Filoviridae, genus Ebolavirus. On 8th of August 2014, WHO had declared the Ebola epidemic in West Africa a Public Health Emergency of International Concern (PHEIC). The symptoms of Ebola infection include fever, fatigue, malaise, and weakness, reddened eyes, joint and muscle pain, headache, nausea and vomiting, abdominal (stomach) pain and unexplained haemorrhage (bleeding or bruising). Image from: http://www.africatopsuccess.com/wp-content/uploads/2014/08/Ebola.jpg - Haemorrhagic fever However, in the year of 2015 and 2016, WHO already declared that the Ebola outbreak has been ended. The WHO declared the end of Ebola transmission in Guinea on 29 December 2015, in Liberia on 14 January 2016, and in Sierra Leone on 17 March 2016. Though the countries are free from Ebola, WHO warned the countries for still being at risk for sporadic transmission of Ebola due to some people who survive from the infectious disease. They are potential to initiate the outbreak and as for that, strong surveillance and emergency response capacity must maintain to avoid any risk of Ebola disease to spread again.

El peligroso Zika también tiene cosas buenas El peligroso Zika también tiene cosas buenas El peligroso Zika también tiene cosas buenas 14/10/2017 Tecnología - Ciencia Por habana91 Científicos de un equipo internacional formado en Estados Unidos informaron en un estudio publicado que una mutación genética en virus del Zika es la causante de microcefalia. Para demostrar esta hipótesis, compararon cepas del virus Zika que circularon durante el 2015 y el 2016 en Brasil con una cepa que se vio en Camboya en el 2010 y las sometieron a análisis genéticos, señala el trabajo divulgado en la revista especializada en temas científicos Science. Como resultado, los expertos brasileños y chinos descubrieron varios cambios en esos años, pero notaron que había siete variantes entre los virus de una y otra época. Pero no todo lo relacionado con el virus es negativo, dijeron. Según argumentaron, esas variantes fueron inyectadas a ratones y observaron que solo una estaba directamente relacionada con anomalías cerebrales en los fetos. Esa mutación,llamada S139N, sustituyó a un aminoácido conocido como serina por otro nombrado arginina en la posición 139, y ese cambio se dio en una proteína estructural, la prM (proteína precursora de membrana, común en los virus), explicaron en el medio especializado. Esa proteína, añadieron está dentro de la capa protectora del patógeno, e hizo también al virus más letal para las neuronas humanas, en comparación con la forma ancestral. Los autores consideraron que esta investigación al aportar mejor comprensión del virus, podría contribuir al desarrollo futuro de medicamentos para contrarrestar ese mal, también asociado con el síndrome de Guillain-Barré (un trastorno autoinmune que afecta al sistema nervioso). Pero por otro lado, y de acuerdo al Instituto Nacional del Cáncer, el glioblastoma es el tumor cerebral más frecuente y agresivo. Puede verse a cualquier edad, pero por lo común afecta primeramente a adultos, con un pico de incidencia entre los 45 y los 70 años. Y al igual que todos los tumores cerebrales, excepto en casos muy raros, no se expande más allá de las estructuras del sistema nervioso central. Siendo uno de los tipos de cáncer cerebrales más mortales (que la mayoría de los pacientes mueren dentro de los dos años del diagnóstico), a la enorme dificultad que conlleva su extirpación dada su localización, se une su elevada resistencia a la quimioterapia y radioterapia. Además, tras su tratamiento inicial las recaídas son muy comunes y las opciones terapéuticas limitadas. En este contexto, la comunidad científica se aboca a hallar variantes terapéuticas. Y una de los más recientes pruebas encontró en el virus del Zika un posible -e inesperado- aliado para combatir la afección. Al menos, es la respuesta que observaron en ratones y cultivos, demostrando que ralentiza el crecimiento y aumenta la esperanza de vida Un trabajo en conjunto de especialistas de la Universidad de California y de Washington utilizaron el virus del Zika en roedores para infectar células madre de glioblastoma derivadas de pacientes. El ensayó resultó altamente positivo, ya que se aminoró el crecimiento del tumor y prolongó significativamente la vida de los animales. El abordaje estándar contra este cáncer incluye la cirugía, la quimioterapia y sesiones de radiación. El objetivo central es matar las células madre de glioblastoma para prevenir que surjan nuevos tumores después que el tumor original haya sido extirpado quirúrgicamente. Sin embargo, las variantes de tratamiento no logran evitar que la mayoría de los tumores se repliquen antes de seis meses, ya que estas células tienen capacidad de resistencia. Partiendo de allí, para eliminar a las células madre de glioblastoma, los científicos emplearon una cepa mutante de Zika, menos virulenta que las cepas naturales y más sensible a la respuesta inmune. "Hemos demostrado que el virus del Zika puede matar al tipo de células de glioblastoma que tienden a ser resistentes a los tratamientos actuales y conducir a la muerte", dijo Michael S. Diamond, catedrático de la Facultad de Medicina de la Universidad de Washington y coautor del estudio. En los resultados, publicados en The Journal of Experimental Medicine, se indicó además que el experimento tuvo mayor eficacia cuando se combinó con el fármaco de quimioterapia temozolomida, que generalmente tiene poco efecto sobre estas células. El próximo paso será realizar ensayos preclínicos para asegurarse que se trata de una opción eficaz y sin efectos secundarios adversos a corto o largo plazo. Milan G. Chheda, experto de la Universidad de Washington, comentó al respecto: "Vemos al Zika siendo empleado un día en combinación con las terapias existentes para erradicar el tumor por completo".

Ebola continues to spread in West Africa, but some countries are poised to declare victory over the deadly virus.
“Our country is facing another epidemic of the Ebola virus,” the country’s health ministry said.
The world is responding much sooner, and differently, to the latest virus than it did to the one that struck West Africa, health officials say.
