A virus<span> is a small </span>infectious agent<span> that </span>replicates<span> only inside the living </span>cells<span> of other </span>organisms<span>. Viruses can infect all types of </span>life forms<span>, from </span>animals<span> and </span>plants<span> to </span>microorganisms<span>, including </span>bacteria<span> and </span><span>archaea
</span>While not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles. These viral particles<span>, also known as </span>virions<span>, consist of two or three parts: (i) the </span>genetic material<span> made from either </span>DNA<span> or </span>RNA<span>, long </span>molecules<span> that carry genetic information; (ii) a </span>protein<span> coat, called the </span>capsid<span>, which surrounds and protects the genetic material; and in some cases (iii) an </span>envelope<span> of </span>lipids<span> that surrounds the protein coat when they are outside a cell. The shapes of these virus particles range from simple </span>helical<span> and </span>icosahedral<span> forms for some virus species to more complex structures for others. Most virus species have virions that are too small to be seen with an </span>optical microscope<span>. The average virion is about one one-hundredth the size of the average </span>bacterium<span>.</span>
The care team would recognize that this patient faces the risk of ACUTE FULMINANT HEPATITIS.
Fulminant hepatic failure refers generally to the development of encephalopathy within 8 weeks of the onset of symptoms in a patient with a previously healthy liver. It results in severe impairment of the hepatic functions.
Out of the following
given choices;
a. Valine instead of glutamic acid in the
sixth position
b. Glutamic
acid replacing valine in the first position
c. Extensive
amino acid substitutions
d. Trinucleotide
repeats
e. Frameshift substitutions
The answer is A. this is caused by a mutation in the beta
thalassemia genes on one of the 46 human chromosomes (chromosome #11) of the individual.
The alpha subunit is normal in people with sickle cell disease. When sickle
hemoglobin releases oxygen in the peripheral tissues, the molecules tend to
stick together and form long chains or polymers. These rigid polymers distort
the cell and cause it to bend out of shape from
the normative disc shape.
Answer:
The implications are epidemies, risk factors and disease burden.
When it comes to Typhoid, the cronic earners are treated with prescribed antibiotics, changes in sanitary habits and blood testing.
When it comes to hepatitis b, the cronic earners are treated with prescribed antivirals, blood tests, liver ultrasound and biopsy.
Explanation:
<em>Epidemies can occur because the sick population, might not be aware and contaminate the other amount who is not infected. That is the reason why the chronic earners must take the prescribed antibiotics for as long as the physician has prescribed, they must incorporate healthy sanitary habits like washing their hands with soap after using the bathroom, not preparing or serving food to other people. Because these actions will prevent others from getting the illness. And finally, they must get tested so that the doctor can ensure that no Salmonella Typhi bacteria remain in their body. The best way to avoid Typhoid is by vaccine.</em>
<em>Hepatitis B epidemies, risk factors and disease burden happens when the chronic earner use illegal injected drugs and share the niddle, have unprotected sex with multiple partners, receive kidney dialysis or live with someone who has hepatitis B. So the best way of managing these patients is by lifetime treatment, which means that they will take antiviral medications, interferon injections or have a liver transplant. </em>
<em>The best way of preventing the hepatitis B is by vaccine, safe sex and no drugs.</em>
