Top 100+ Biotechnology Interview Questions And Answers

Question 1. Do You Know How The Dose For Children Is Being Estimated Based On Preclinical Data?

Answer :

           There are a number of methods of estimating children's doses from preclinical (grownup) statistics - frequently relies upon on the healing index of the drug in question (the broader the therapeutic window the much less correct the kid's dose desires to be). Sometimes directly weight-basis i.E. 7kg baby receives 1/10 dose of 70kg person.
           More correct (so that they say) is a dose based on frame floor area (baby's floor vicinity is greater in proportion to its frame weight than an adult is). There are normograms to calculate surface region from weight and peak of infant.
          All of those can be wrong if clearance of drug in infant is considerably exceptional from adult e.G. Special metabolism or specific direction of clearance.

Question 2. What Is The Definition Of “biomedical”? What Topics Cover The Study Of Biomedical Sciences?

Answer :

The time period "biomedical" covers a giant range of subjects - the whole lot that relates biology to medicinal drug. This can range from the obvious like Anatomy, Biochemistry, Physiology, Microbiology, Pharmacology, Genetics to the less obvious like Botany (maximum capsules have been firstly derived from plants and, as a consequence, those is a huge technological know-how called Phytopharmacology).

Bio Interview Questions
Question 3. Is Phenoxyethanol Harmful?

Answer :

Phenoxyethanol is dangerous and can be absorbed via the pores and skin - legitimate web sites for toxicity facts, however, show little toxicity in guy and a few toxicity (inflammation) with excessive doses in animals. Phenoxyethanol is in cosmetics as a bactericide (kills micro organism).

Question four. Why Is Buprenorphine Less Addictive Than Other Opioids (like Fentanyl) - Is It Explainable By Its Strength Of Binding To The Common Receptor, Or?

Answer :

Buprenorphine is what is known as a partial agonist - i.E. It binds to the receptor but even at its most can't supply as a great deal of an effect as a complete agonist (along with morphine) - it's far, thus, additionally a partial antagonist (partially inhibits the actions of full agonists).
          As addiction is in all likelihood to be linked to electricity of the effect of the drug, buprenorphine has less effect and, consequently, much less addiction.

Question 5. How Is The Concentration Of Drugs In Human Plasma Defined?

Answer :

Some tablets bind drastically to plasma proteins (Warfarin binds 99%) whereas others have really no binding.
Extraction depends on the sort of drug - there are one of a kind trendy techniques for acidic, basic, and impartial tablets - and, indeed, some pills want specific extraction techniques.
It is crucial for you doing bioequivalence research to recognise precisely the proportion of drug extracted however such controls are once more specific for each drug and use precise marker compounds.

Nursing Interview Questions
Question 6. How Is The Calculation Derived For A Drug To Be Bio Equivalent With Other? On Which Base The Limit Is Fixed As 80-120% For A Drug To Be Bio Equivalent. What Is Meant By ninety% Confidential Interval?

Answer :

To be "bioequivalent"  arrangements or capsules need to present the identical organic effect.
The standard "experimental mistakes" put on that is 20% - as a result, 80-a hundred and twenty% is taken into consideration "bioequivalent.”
90 percentage self assurance c language way that statistically it is ninety% sure that the outcomes are equal.

Question 7. When We Do Liquid Extraction, What Is The Effect Of Adding 10%acid Or Any Base And How Do We Know Which Has To Be Added And Up To Which Concentration Or Micro Litre Level Can We Add Such Buffers? If Any Gel Formation Occurs At The Time Of Extraction, How Will It Affect The Analysis? Shall We Continue The Extraction With The Same Or Should We Drop That Method?

Answer :

The idea of including acid/base is to alternate the lipid (and consequently organic solvent) solubility of the additives you want to extract.
For example, a fatty acid is more soluble in water as a salt (and, hence, in basic situations) while it is essentially insoluble in water in its uncharged kingdom (in acid conditions). So adding acid to the solution of fatty acid salt in water will render it water-insoluble and, for this reason, circulate it from the water to the organic solvent.
This is a trendy extraction technique for natural acids and bases. Also, observe that specific concentrations of acid/base want to be calibrated for every extraction.
Gel formation is hard to deal with, as you can't make certain of the extraction (difficult to mix and separate). We could advise converting the method except you can display a first rate extraction or the outline of the method says to count on a gel formation.

Question 23. Explain In Brief About Leukotrienes And Prostaglandins?

Answer :

Leukotrienes and prostaglandins are fashioned simplest whilst the mast cellular undergo degranulation and enzymatic destroy down of phospholipids within the plasma membrane.

The consequences produced with the aid of them are extra reported and durable than histamine. Leukotrienes mediate mucous production and bronchoconstriction. Prostaglandin D2 reasons bronchoconstriction.

Question 24. Explain In Brief About Cytokines?

Answer :

Cytokines prompt inflammatory cells such as neutrophils and eosnophils.IL-5 is vital in activation of eosnophils, IL-four increases IgE production via B-cells. IL-4, Il-5, IL-6, TNF-a has been secreted with the aid of human mast cells.
