The fact that the H7N9 virus has only recently infected humans helps explain why

Answers

Answer 1

Answer:

Because the H7N9 avian virus acquired pathogenic mutations in order to infect mammalian hosts

Explanation:

H7N9 is a subtype of influenza avian viruses that has recently been reported to infect humans. Fortunately, H7N9 has also been reported to have a low pathogenic level; however, mutations might change this level to become more infectious for humans. Consequently, mutations in a given H7N9 strain might enable its adaptation and higher affinity to human-type receptors, being more aggressive to human cells, especially in lung cells, since this virus is characterized by rapid progression and respiratory failure.

what is drug metabolism

Answers

Answer:

Drug metabolism is the chemical alteration of a drug by the body.

Explanation:

Some drugs are chemically altered by the body (metabolized). The substances that result from metabolism (metabolites) may be inactive, or they may be similar to or different from the original drug in therapeutic activity or toxicity.

Answer:

Metabolism of drugs is the term used to describe the bio-transformation of pharmaceutical substances in the body so that they can be removed more conveniently. The large proportion of metabolic processes involving drugs are present in the liver, as enzymes that facilitate reactivity are focused there.

Explanation:

Drugs are metabolized by various reactions, such as:

OxidationReductionHydrolysisHydrationConjugationCondensationIsomerization

For certain instances, as a medication becomes metabolized, it is inactivated. However, the metabolites of some drugs are pharmacologically active and have an impact on the body. In fact, the active metabolite of some drugs is responsible for the entire action of the drug. In this scenario, the type of the medication is referred to as a pro-drug.

O Premature loss of the restorative material
O Premature contact on the restorative material
O Post-operative sensitivity and damage to the pulp
o Occlusal trauma

Answers

Answer:

Post-operative sensitivity and damage to the pulp

Explanation:

Protective bases are applied to the pulp during the process of dental operations. These protective bases are usually applied in a thickened manner. This helps to prevent post operative sensitivity to substances such as cold sensations. The pulp is also protected as a result of the application of protective bases.

This makes Protective bases being placed when it is necessary to protect the pulp before the restoration is placed in order to prevent Post-operative sensitivity and damage to the pulp valid.
