RNA virus

an acute transmittable disease caused by varicella zoster virus. [4] However, it is often times considered to be a relative mild childhood disease. Chickenpox is easily spread, and can be spread before symptoms are shown. It can be acquired when a person with the virus, sneezes or coughs. It enters the respiratory system, and the infection concentrates in the skin cells for about two weeks. [4] It can also be contracted by touching the virus particles that come from chickenpox blisters or from…

Daniel Noe Summary - Gene Transfer Properties and Structural Modeling of Human Stem Cell-Derived AAV The ability of adeno-associated virus (AAV) to establish latency without helper virus coinfection has made AAV useful as a gene therapy vector. In addition, AAV is able to maintain transgene expression in the absence of toxicity in vivo. AAV virus serotypes are abundant and novel genomes from primate tissues continue to be discovered. This has led to the creation of a variety of AAV vectors with…

“Chickenpox is caused by the varicella-zoster virus (VZV), chickenpox used to be a common illness among kids under the age of 12 (The Nemours Foundation, 2014).” An itchy rash of macules, papules, vesicles, pustules, and scabs appears with chickenpox, all stages are present on the body at the same time. “The incubation period is the time between the invasion by the pathogen and the onset of clinical manifestations, the incubation period for chickenpox is 2-3 weeks (Leifer, 2011).” An infected…

Would you change your unborn child if you had the chance? Would you want your child to have light or dark hair? Perhaps, blue eyes instead of brown or vice versa? How about his or her hobbies? What about their thought process concerning knowledge and intellect? Would you be a parent to take advantage of human gene editing to benefit your child? The purposely changing genes that are passed on to a child and future generations create genetically modified individuals. This gives the opportunity to…

As biotechnology continues to advance, a matter that interests both genetic and conservation scientists is the de-extinction of species, or the resurrection of lost species. The idea of Jurassic Park, a 1993 American film where genetic scientists created a wildlife park with cloned dinosaurs, is no longer science fiction. It is becoming an increasingly considered possibility, and with the present-day extinction rate of species higher than ever, scientists have commenced to ponder the prospect of…

caused by the Variola virus. This report explores the taxonomic classification, “life cycle”, and mechanism of replication of this pathogen, as well as discusses the virulence and treatment options for an infected human host. This member of the Orthopoxvirus genus is extremely virulent, and has a fatality rate of nearly 30%. While this virus only attacks a human host, similar members of the Voxviridae family produce similar infections in animals. Transmission of the variola virus requires…

search for a cure, but when told she could not speak to Dr. Jonathon Mann without an appointment, she broke down in tears. This, in my opinion, was one of the most emotional and effective moments in the film. It showed not only the effects of the virus on the individual itself, but loved ones around them as well. Dr. Mann enountered Irine and explained that even though there was no cure yet and that her husband would eventually die, there was a prejudice attatched to AIDS that they had to…

To correct the mutation in the gene that lead to the development of cystic fibrosis, a team of Yale researchers led by Dr. Peter Glazer (Chairman, therapeutic radiology), Mark Saltzman (Chairman, biomedical engineering), and Dr. Marie Egan (professor of paediatrics and of cellular and molecular physiology), the collaborative team operated certainartificial molecules identical to DNA known as Peptide Nucleic Acids (PNAs), as well as donor DNA, to recover the genetic abnormality.Professor Egan…

Varicella Zoster Virus (VZV) is a member of the Herpesviridae family, that causes two different infections: varicella and herpes zoster. This paper will include information on the history of Varicella Zoster Virus and how to treat it. Most people know varicella as chickenpox, which is a modified version of the previous term: chicken peas. It was previously called chicken peas because the red rash that appear resembles the vesicles of chickpeas (garbanzo beans) or chicken pecks. Red, itchy spots…

Cold sores are inflamed, fluid-filled blisters in or near the mouth caused by the herpes simplex virus. They range in all different sizes and shapes. Cold sores are caused by the herpes simplex virus strain HSV-1. People who get cold sores after having oral sex with someone who has genital herpes can cause a rare strain that is known as HSV-2. Cold sores can also be genetic. The Prodromal Stage is all of the symptoms that occur before the cold sore. Some symptoms may include, burning,…
