5. What is (LMO) Living
Modified Organism?
Ans.Living Modified Organism means any living organism which contains genetical material in it by using modern bio technology. It could be sterile, injections or virus.
Usually in Bio-Technology interviews, applicants will be asked to handle a seminar about their main scientific subject.
In this scenario, applicant should check before with the HR as to who will be the audience and what the exact skill sets are they are looking for to fill this
position. This will help the applicant do a research on it before hand and can get fully prepared for a seminar. The applicant should make sure that the presentation

about their company and business press. Find out if they have any competitors and do research on them. You could talk about adopting their style of working for any
improvement in this company.

14. How is the concentration of drugs in human plasma defined?

specific marker compounds.

15. Why is buprenorphine less addictive than other opioids (like
fentanyl) – is it explainable by its strength of binding to the common
receptor, or?
Ans.Buprenorphine is what is referred to as a partial agonist – i.e. it binds to the receptor but even at its maximum cannot give as much of an effect as a full agonist
(such as morphine) – it is, thus, also a partial antagonist (partially inhibits the actions of full agonists).
As addiction is likely to be linked to strength of the effect of the drug, buprenorphine has less effect and, therefore, less addiction.

18. Do you know how the dose for children is being estimated
based on preclinical data?
Ans.There are a number of ways of estimating children’s doses from preclinical (adult) data – often depends on the therapeutic index of the drug in question (the wider the
therapeutic window the less accurate the child’s dose needs to be). Sometimes straight weight-basis i.e. 7kg child gets 1/10 dose of 70kg adult.
More accurate (so they say) is a dose based on body surface area (child’s surface area is greater in proportion to its body weight than an adult is). There are
normograms to calculate surface area from weight and height of child.
All of these may be wrong if clearance of drug in child is significantly different from adult e.g. different metabolism or different route of clearance.

Here is a great herbal doctor who cured me of Hepatitis B. his name is Dr. Imoloa. I suffered Hepatitis B for 11 years, I was very weak with pains all over my body my stomach was swollen and I could hardly eat. And one day my brother came with a herbal medicine from doctor Imoloa and asked me to drink and I drank hence there was no hope, and behold after 2 week of taking the medicine, I started feeling relief, my swollen stomach started shrinking down and the pains was gone. I became normal after the completion of the medication, I went to the hospital and I was tested negative which means I’m cured. He can also cure the following diseases with his herbal medicine...lupus, hay fever, dry cough, diabetics hepatitis A.B.C, mouth ulcer, mouth cancer, diarrhoea, liver/kidney inflammatory, eye cancer, skin cancer disease, malaria, chronic kidney disease, food poisoning, parkinson disease, bowel cancer, bone cancer, brain tumours, asthma, arthritis, epilepsy, cystic fibrosis, alzhemer's disease, acute myeloid leukaemia, acute pancreatitis, Addison's disease back acne, breast cancer, allergic bronchitis, Celia disease, bulimia, congenital heart disease, cirrhosis, constipation, fungal nail infection, fabromyalgia, (love spell) and many more. he is a great herbalist man. Contact him on email; drimolaherbalmademedicine@gmail.com. You can also reach him on whatssap- +2347081986098.
