Though the cells have been beneficial to the entire society, the way they were extracted, and the way they are being used has been criticized by many authors. Despite criticism, HeLA cells are still being used for every aspect in science today, and are being used to develop vaccinations that can fight the Ebola Virus, which has become a great threat to human beings.
“The Immortal life of Henrietta” by Rebecca Skloot highlights how HeLa cells have been beneficial to the entire world. On October, 4, 1951, Henrietta Lacks, a 31 year old woman, and a mother died of cervical cancer. As it was the norm to take biopsy samples from patients, doctors took her cancerous tumors to enhance their study. However, this was done without her knowledge. Doctors, George Gey and Mary Kubicek, overcame laboratory failures, and succeeded in keeping human cancer cells alive and growing forever. Since then, the HeLa cells have been used to develop important vaccines and cancer medicines. In Skloot’s book she writes that the cells are also being used in processes such as cloning, gene mapping, as well as in vitro fertilization (Skloot 369). Moreover, cancer survivors who were being treated alongside Henrietta were not aware until mid-1970s that the cells from Henrietta’s cancer have been used to save their lives. After this discovery, many medical researchers sought to know more about the cells, and why they are special. University of Minnesota scientists discovered that the cells could be infected with a virus that causes polio. With this knowledge the cells provided a quick way test of the usefulness of the Salk polio vaccine. It was discovered that if vaccinated patients produced antibodies that would prevent the disease, his or her blood plasma would prevent polio when it mixed with HeLa cells and poliovirus in laboratories. The research has been operated and funded by African-American researchers

The Ebola virus is a distinct, rod-shape virus in the family of Filoviridae. They produce acute hemorrhagic fever in mankind. Some of the clinical manifestations of the virus might be similar to the Lassa fever or yellow fever but if cluster of these cases occurs, one can identify the unique, approximately 6 days following bloody diarrhea, a maculopapular may appear accompanied by substantial bleeding at needle sites and bodily orifices characteristics of the Ebola virus.
This paper will discuss about the Ebola virus and its history. Also, Ebola has five different strains that each came from separate natural reservoirs. Next, how Ebola is transmitted and what is the natural host. Other ideas that will be touched on include the signs and symptoms of the disease and how it manifests itself.
The sports events and the authorities organizing them around the world do not support any form of doping because the persons using such drugs get an iniquitous edge over the other participants who do not use it. Lance Armstrong the American
The CDC estimates of Ebola virus reported that actual cases in Sierra Leon, Liberia and Guinea were two to three times higher than the officially reported statistics. Ebola virus epidemic in West Africa concurrently has caused a significant decline
Hence one of the best solutions relies mainly on prevention. Strictly implementing security procedures to lessen contact or interaction people and continuously updating the public of the epidemic’s status
ow, the average case fatality rate for the EVD is 50% though their rates has been shifting from 25% to around 90% for the past outbreaks as evidenced in the West Africa according to CDC (2014). EVD epidemics as reported by the National Notifiable Disease Surveillance System
Its endocytosis into macropinosomes occurs there. Fusion of viral membrane with vesicle membrane facilitates its penetration into the cell, and nucleocapsid generates into cytoplasm. Encapsidated negative-sense genomic ssRNA helps synthesize
More specifically, it is important to note that Ebola is caused by an infection that belongs to the family Filoviridae and genus Ebolavirus. Presently, four species of the identified Ebola virus directly affect humans with the remaining one affecting nonhuman
ference to the World Health Organization (WHO), the Ebola fatalities average to about ninety percent of all the infected persons (Peters and LeDuc ix). Despite the high fatality rates, the illness still lacks proper mechanisms of treatment. Ebola is found to be caused by the
