be averted. After some experiments provided questionable results, I was given the task of confrming that the viruses we were working with had been packaged and identifed correctly. I spent weeks running DNA gels, looking for specifc genes in each virus, but my results were inconsistent. I was frustrated, but instead of giving up on my assignment, I was even more determined to fnd an explanation. I considered every aspect of the experiment, working backwards until I reached the…

An example of this is the 1918 influenza pandemic, strain H1N1 which was identified to have originated in birds and killed between 40-50 million people2. The influenza A virus (IAV) is a member of the orthomyxoviridae family and has a negative sense, single stranded RNA genome split into 8 segments, containing 11 genes. The virus possesses a lipid envelope which is produced from the host cell. Spikes protrude from this membrane which consist of hemagglutinin (HA), which facilitates receptor…

the export of RNPs by producing nuclear export signals and binding with RNP to form a complex that can be exported (Paterson and Fodor, 2012). M proteins also plays crucial role when the new virus buds off. It blocks the nuclear pores to stop re-entry of the newly formed RNAs and allows assembly of the new virus. M proteins can bind the phospholipid tail of the cell membrane with the viral envelope of the glycoproteins around the encapsidated RNA and bud off the host cell (Figure 1)…

Scabies is a parasitic STD, and can be spread by skin to skin contact with a person that has scabies. Scabies is quite common, around 1 million people get infected with scabies each year. Some symptoms of scabies can be intense itching usually at night, small bumps or rashes, on fingers, butt, breasts, wrist, and thighs. http://www.mayoclinic.org/diseases-conditions/scabies/basics/definition/con-20023488 Your doctor can test for scabies by using a microscope or sometimes taking a biopsy of the…

get genital herpes. You get genital herpes by having vaginal, anal, or oral sex with someone who has the disease. Fluids found in a herpes sore carry the virus and contact with those fluids can cause infection. You can also get herpes from an infected partner who does not have a visible sore or who may not know he or she is infected because the virus can be released through your skin and spread the infection to your partner. The only way to avoid STDs is to not have vaginal, anal, or oral sex.…

What is Herpes? Herpes simplex virus (HSV) is a viral infection that is caused by multiple herpes viruses. They can produce cold sores, genital inflammation or even conjunctivitis. There are two types of herpes simplex viruses, HSV-1 and HSV-2. HSV-1 is also known as oral herpes. It can cause cold sores and fever blisters around your mouth and/or on your face. HSV-1 is less contagious than . While as HSV-2 generally is responsible for genital herpes outbreaks. What is Zosters?…

Recent study reveals cat-scratch disease is rising among adults Say goodbye to regular cuddle sessions with your beloved kitty, because their claws could harm you. According to a recent study by the Center for Disease Control and Prevention (CDC), there has been an increase in cat-scratch disease (CSD) patients. The study revealed that 13,273 people were diagnosed with CSD during 2005-2013, and 538 of the diagnosed patients were later hospitalized. CSD is a bartonella bacterial infection…

By Jonas Wilson, Ing. Med. Lichen striatus Lichen striatus (LS), also known as Blaschko linear acquired inflammatory skin eruption or linear lichenoid dermatosis, is a benign, rare and self-limiting inflammatory skin condition. It primarily affects children between the ages of 5 to 15 years. LS initially presents as pinkish-red or flesh colored spots that coalesce over a two-week period (or less) to form a dull and scaly linear band. Lesions associated with LS tend to occur more frequently…

may be altered to treat a disease, it won't change the chance that the disease will be passed on to the patient's children. This is the more common form of gene therapy being done.” (Gene Therapy and Kids.) This type involves attaching the gene to a virus called a vector. The other type is germline. Kids Health says, “(Germline gene therapy)Involves modifying the genes in egg or sperm cells, which will then pass any genetic changes to future generations. Experimenting with this type of therapy,…
