The major features of
schizoaffective disorder which clearly delineate it from schizophrenia are marked
symptoms of schizophrenia coupled with major depressive episode or manic
episode. Both schizoaffective disorder and schizophrenia are primary psychotic
disorders.
Answer:
The correct answer is Glycocalyx, ribosome and cell wall.
Explanation:
Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.
Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.
Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.
So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
When you want to either touch something to figure out whether or not it might be harmful or not. And we also use our sense of touch when we might be looking for an object, when you touch the object immediately your brain knows what it is.
Answer:
Mannitol is a drug that temporarily disrupts tight junctions. This drug is often added to medications that need to get into the extra-cellular fluid of the brain because it will make the capillaries of the <u>blood-brain barrier </u>more permeable to larger molecules.
Explanation:
The blood-brain barrier's components are endothelial cells, basement membrane, pericytes, and astrocyte endfeet. The gaps between endothelial cells are small. As a consequence, they form tight junctions that allow the passage of specific and small molecules. In this way, the barrier stops any pathogen from entering the brain. That is to say, that the blood-brain barrier is extremely selective; therefore, medications will not pass through it, so to allow the medicine to enter the brain extracellular fluid, the tight junctions of the endothelial tissue must be disrupted with mannitol.
<span><em>Hyponatremia</em> is a condition that occurs when the concentration of sodium in the blood is too low. Sodium is critical in homeostasis because it maintains the fluid balance. In other words, it helps control the amount of water that circulates in the body. When sodium levels are low it becomes diluted and as a result, the body will have an excess of water, specifically extracellular fluid.
The excess fluid will have nowhere to go, so it goes into the cell. When this happens, it causes the cells to swell, which can lead to several health problems and some of them are life-threatening like cerebral edema. </span>
