Question
Chapter 37, Problem 3DAA
Summary Introduction
To determine: Whether is it possible to estimate from this graph the overall risk of cervical cancer that is associated with the infection of cancer-causing HPV of any type.
Concept introduction: The researchers in this study attempted to make a connection between the presence of various HPV viral infections and the incidence of cervical cancer. Cervical cancer is the cancer that arises from the cervix, which occurs due to the unusual growth of cells that have the capability to invade or spread to other body parts.

Immunology Case Study to study
A 34 week pregnant women called her obstetrician as she was worried after coming down with a fever and sore throat. The doctor ordered EBV testing and CMV antibody testing. EBV testing was negative, but the mother demonstrated a four fold increase in CMV IgG after a 14 day interval.1. What is the definitive testing to be done to confirm CMV infection in the mother?
2. What are the chances her newborn will be born with symptoms of congenital CMV?
3. Why are CMV screenings on all pregnant women not a part of routine prenatal care?
4. What antibody class (IgG or IgM) would point to CMV infection in newborn testing?
Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below.
The above graph is looking at the relative entry of SARS-CoV2 isolated spike proteins into human cells in culture at two times points: before introduction of the virus to the cell culture (0 minute) and 5 minutes after introduction of the virus to the cell culture. CHC stands for "clathrin heavy chain" and siRNA stands for small interfering RNA, which is often used in experiments as an easy method to stop expression of a certain gene. So in this case, the CHC siRNA would stop cellular production of CHC. The control siRNA introduces a small RNA fragment that does not match any gene as a negative control. From the above figure, you can conclude what about the process that allows the SARS CoV-2 virus entry into the cell?
Options:
The spike protein is not involved in cell entry, contrary to popular belief
This is evidence for clathrin-mediated endocytosis as the…

- Question 1 Nursing. Innate lymphoid cells reside primarily in tissues such as the lungs, the lining of the gastrointestinal tract, and the skin, because these sites represent the major routes of entry of pathogens into the body. Several different subsets of innate lymphoid cells exist, and each is specialized to respond to a category of pathogen (e.g., viruses, extracellular bacteria, helminthic parasites, etc). a) True b) Falsearrow_forwardPart B - Viral Classification: The Baltimore Scheme The Baltimore classification scheme is based on the relationship between the virus' genome and its mRNA. For the following choices, indicate which viruses would fall into each classification: 1) require reverse transcriptase to copy the information in their own genome to DNA; 2) can replicate and be transcribed in the same manner as the cell's own genetic material; and 3) a replicative form of DNA must be produced and is used for both replication and transcription. Drag and drop choices to the bins they describe. double-stranded DNA viruses Requires reverse transcriptase double-stranded RNA viruses retroviruses double-stranded DNA viruses that have an RNA intermediate Functions similarly to cell's own genetic material plus-strand RNA viruses minus-strand RNA viruses Reset Help plus-strand DNA viruses Uses a replicative form of DNAarrow_forwardFill in the blanks. The parentheses represent the choices for the blank. Scientists already knew that a special type of virus called a bacteriophage inserts genetic information into a bacterial cell in order to force the bacterial cell to make more bacteriophage viruses. What scientists did not know, however, was whether that genetic information is carried by the (proteins, DNA) covering the outside of the bacteriophage virus or by the (proteins, DNA) inside the bacteriophage virus.arrow_forward
- From: "Towards a universal flu vaccine" Each year, the flu vaccine includes antigens from two strains of Influenza A and two strains of Influenza B. These antigens are from the head of the H spikes an area that sticks out from the virus and so, is very easy for human immune cells to detect. However, the problem with using the head of the H spike as an antigen is... O The H spike head mutates very rapidly, so quickly changes to forms not recognized by human immune cells. O The H spike head is exposed on the surface of the virus for only a short period of time. Viruses quickly pull the H spikes back inside the virus, shiclding them from human immune cells. O The H spike head is often too big for the human immune cells to attack. O The H spike head is often too small for the human immune cells to bind to.arrow_forwardplease tell me how bacteriophage and animal viruses multiply. please add both lytic and lysogenic cycles for bacteriophage, all steps, and the outcomes of both.
