These ceramic nanoparticles are surface functionalized with arginin-glycine-aspartic acid peptide ligands and radioiodine. They exhibit higher affinity and residence in tumours and peripherial blood fluids. What are they?

These ceramic nanoparticles are surface functionalized with arginin-glycine-aspartic acid peptide ligands and radioiodine. They exhibit higher affinity and residence in tumours and peripherial blood fluids. What are they? Correct Answer Multimodal silica nanoparticles

Multimodal silica nanoparticles are found to be effective markers in cancer diagnosis and imaging. They are surface functionalized with arginin-glycine-aspartic acid peptide ligands and radioiodine. They show higher affinity and residence in tumours and peripherial blood fluids.

Consider the following statements about the Open and Closed Blood Circulatory System:   A) Open blood circulatory system does not contain special blood vessels to carry oxygenated and deoxygenated blood, while in the closed blood circulatory system blood vessels are present. B) Oxygenated and Deoxygenated blood gets mixed in the closed blood circulatory system, while oxygenated and deoxygenated blood does not get mixed in the open blood circulatory system. Choose the correct statement.
In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
Analysis of a hexapeptide using enzymatic cleavage reveals the following result:
• Amino acid composition of the peptide is: 2R, A, V, S, Y
• Trypsin digestion yields two fragments and the compositions are: (R, A, V) and (R, S, Y)
• Chymotrypsin digestion yields two fragments and the compositions are: (A, R, V, Y) and (R, S)
• Digestion with carboxypeptidase A yields no cleavage product.
Given: Trypsin cleaves at carboxyl side of R. Chymotrypsin cleaves at carboxyl side of Y. Carboxypeptidase A cleaves at amino side of the C-terminal amino acid (except R and K) of the peptide.
The correct amino acid sequence of the peptide is:
In the following question, the first and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts and named P, Q, R, S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. S1. Blood donation refers to a practice where people donate their blood to people so it helps them with their health problems. P. It is also a sign of humanity that unites people irrespective of caste, creed, religion, and more. Q. If the body loses blood in excessive amounts, people to get deadly diseases and even die.  R. Blood is one of the most essential fluids of our body that helps in the smooth functioning of our body. S. Thus, we see how blood donation is literally life-saving which helps people. S6. To raise awareness about this life-saving procedure, the world observes 14th June as Blood Donor Day.

Consider the following statements regarding corrosion of ceramic material: 1. Ceramic materials are much better suited to withstand most of these environments for reasonable time periods than are metals. 2. Corrosion of ceramic materials generally involves simple chemical dissolution, in contrast to the electrochemical processes found in metals. 3. Ceramic materials are not frequently used because of their non-resistance to corrosion. Which of the above statements is/are correct?
Statement 1: For non-Newtonian fluids, another term called apparent viscosity is used as their viscosity changes with the change in the shear rate. Statement 2: For non-Newtonian fluids, between the transition region, the power number for non-Newtonian fluids is slightly higher than that for Newtonian fluids.
Under the ABO method, a person with an unknown blood group loses a lot of blood in a road accident and needs an immediate blood transfusion. A friend of his, who has a valid certificate of his blood group, requests for blood donation without any delay. The blood group of the blood donor is:
In a blood donation camp, 100 people donated blood. 37 of them had blood group ’A’, 31 had blood group ‘B’, 14 had blood group ‘O’ and rest had blood group ‘AB’. If a sample is chosen at random, what is the probability that the sample contains blood of group ‘AB’?
