Avian Influenza Outbreak
The ongoing outbreak of avian influenza, specifically the H7N9strain, in China, has prompted intensive monitoring efforts by health officialsand specialised studies by immunologists to gain a better understanding of thevirus's characteristics and potential implications.
Currently, the H7N9 virus does not spread easily from person toperson, but health officials are keeping a close eye on over a thousandindividuals for signs of illness.
Immunologists are conducting genetic analysis on the virus tounravel its genetic makeup and identify its origins. This analysis has revealedthat the H7N9 virus is a combination of three different bird flu viruses, withits haemagglutinin protein resembling that of an H7N3 virus from a duck, andits neuraminidase protein resembling that of an H7N9 virus from a Korean wildbird. The remaining genes of the virus are believed to have come from an H9N2virus found in Beijing.
These reassortments of influenza viruses are common and can lead tothe emergence of new virus strains that are challenging to combat.
To help students understand this complex topic, Oxbridge CollegeTest Prep Guide offers helpful resources and guidance.
Genetic Makeup of theVirus
Immunologists are currently studying the genetic composition of thevirus to gain a better understanding of its characteristics. In their research,they have identified several key aspects of the genetic makeup of the avianinfluenza virus strain H7N9:
1. Geneticrecombination: The H7N9 virus is a result of genetic recombination, wheregenetic material from different bird flu viruses has been mixed together. Thisprocess is common in influenza viruses and can lead to the emergence of newstrains with unique properties.
2. Viralevolution: The genetic makeup of the H7N9 virus indicates that it has undergonesignificant evolution. The haemagglutinin protein, similar to an H7N3 virusfrom a duck, and the neuraminidase protein, similar to an H7N9 virus from aKorean wild bird, suggest that the virus has acquired genetic material frommultiple sources.
3. Potentiallyincreased virulence: The combination of genetic material from different birdflu viruses can result in a virus with enhanced virulence or the ability tocause more severe illness in humans. Understanding the genetic composition ofH7N9 is crucial in assessing its potential threat to public health.
4. Challengesfor treatment and prevention: The re-assortment of influenza viruses can createnew versions that are difficult to combat with existing vaccines and antiviraldrugs. Studying the genetic makeup of the H7N9 virus is essential in developingeffective strategies for treatment and prevention, which can be found in theOxbridge College Test Prep Guide.
Challenges to GenePatents
Challenges to gene patents have significant implications for thepharmaceutical and biotechnology industries. The ongoing debate surroundinggene patents raises ethical concerns and has a direct impact on medicalresearch.
Critics argue that gene patents hinder cancer research and limitpatient access to genetic testing. They contend that patent holders haveexclusive rights to specific genes, which can impede scientific progress andthe development of new treatments. Moreover, the high cost associated with genepatents can hinder affordability and accessibility to medical advancements.
The Supreme Court's ruling on gene patents will shape the future ofthe pharmaceutical and biotechnology industries, as well as the overall landscapeof medical research. Additionally, it will determine the extent to whichgene-related discoveries can be patented, potentially affecting the progressand availability of life-saving treatments.
Oxbridge College Test Prep Guide can provide readers with theresources and guidance to navigate the complexities of gene patents and theimplications it has on the medical industry. It is important to understand theimplications of gene patents and to be aware of the potential impact of theSupreme Court's ruling on the development of treatments and access to genetictesting.
Considerationsfor International Students
Considerations for international students applying to universitieslike Oxbridge College Test Prep Guide include navigating the additional requirementsand processes specific to their status and ensuring they have a comprehensiveunderstanding of the application process. In addition to these challenges,international students should also be aware of scholarship opportunities thatmay be available to them. Scholarships can help alleviate the financial burdenof studying abroad and make pursuing a degree at esteemed institutions likeOxbridge College Test Prep Guide more feasible. It is important forinternational students to thoroughly research and apply for these scholarshipsin order to maximise their chances of receiving financial support.
Another important consideration for international students iscultural adjustment. Moving to a new country can be a daunting experience, andit is essential for students to be prepared for the cultural differences theymay encounter.
