Answer:
Answer is option C.
"This drug sometimes provides a complete cure of inflammatory bowel disease.''
Explanation:
- Crohn’s disease is a type of inflammatory bowel disease (IBD) that is caused by autoimmune or genetic factors. It affects any part of the gastrointestinal tract (from the mouth to the anus) and causes abdominal pain, fever, diarrhea, weight loss, etc.
- There is no known cure for Crohn's disease, but therapies can bring about long-term remission by greatly reducing the symptoms. For patients who have not had success with other medical therapies, Infliximab (Remicade) is used.
- Infliximab is a chimeric monoclonal antibody that binds to and neutralizes a key biologic response mediator called tumor necrosis factor-alpha (TNF-α) on the cell membrane and blocks its activity by destroying TNF-α producing cell, thus decreasing inflammation.
- For Crohn’s Disease, the FDA approved dose for adults is 5 mg/kg IV at 0, 2 and 6 weeks, then every 8 weeks.
- The common adverse reactions include urinary tract infections, upper respiratory infections and infusion-related reactions such as headache, fevers, chills, abdominal pain, diarrhea, nausea, hives, rash, shortness of breath, hypotension or hypertension, anaphylaxis, pruritus, convulsions, etc.
- Patients treated with infliximab are at increased risk for developing serious infections such as tuberculosis, fungal infections (histoplasmosis, candidiasis, blastomycosis, pneumocystosis, etc), bacterial, viral and other infections due to pathogens like Legionella and Listeria.
Answer: Somatic nervous system
Explanation:
The voluntary nervous system or somatic nervous system the part of the PNS (peripheral nervous system) which is associated with the voluntary control of the body movements.
These movements are generally controlled by the skeletal muscles. It helps in various movements such as walking, bending, sitting, et cetera.
This nervous system consists of the efferent nerves and afferent nerves or we can say motor nerves that helps in controlling the movement of the body.
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA.
Explanation:
The G2 DNA damage checkpoint is an important cell cycle checkpoint in eukaryotic organisms that ensures that cells don't initiate mitosis until damaged or incompletely replicated DNA is sufficiently repaired. Cells that have a defective G2 checkpoint enter mitosis before repairing their DNA, leading to apoptosis or death after cell division.
