To write:

How cytomegalovirus subverts the ability of NK cell receptors to mediate immune responses.

Introduction:

NK cells are key modulators of immunity as they are involved in cytotoxicity. They are most important in viral infections as they produce interferon gamma (IFN-γ) against the viruses. They are said to holds some properties involving memory towards viral antigens which provides some degree of passive immunity. The cytomegalovirus downregulates NK cell receptors involved in the activation of NK cells.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
