Answer:
RNA interference
Explanation:
The RNA interference (RNAi) pathway is a naturally occurring mechanism in which regulatory non-coding RNAs (ncRNAs) suppress gene expression by targeting messenger RNAs (mRNAs). The RNAi technique is used in molecular biology laboratories and biotechnology applications to reduce the expression of target genes by delivering small interfering RNA (siRNA) molecules targeting a gene of interest. These siRNAs are artificially synthesized to bind by complementarity to the target mRNAs, thereby they can be used for transient gene silencing. This technique does not require genetic modification of the cells, since RNAi can be achieved by direct exogenous delivery of siRNAs.
The nurse must intervene to the patient by persuading him to stop smoking.
The cigarettes are responsible for this ischemia
*Smoking reduces the amount of oxygen in the blood, causing shortness of breath and impaired muscle function.
*Smoking hurts the arteries, causing life-threatening spasms.
*Smoking affects the blood clotting, promoting, among other things, the formation of clots and therefore the potential trigger of an infarct, phlebitis or stroke.
*Smoking causes inflammation of the blood vessels, which also causes clots to form.
*Smoking lowers the level of good cholesterol, which is a long-term risk factor for the cardiovascular system.
The implication of alcohol consumption in lower limb ischemia is still debated
A Trombe wall (Trombe rhymes with prom, by the way) is a wall that warms trapped air, and then circulates it to help heat a house. Trombe walls are ideally made out of a material with a fairly high thermal mass materials (like bricks or concrete), and are often painted black to improve heat conduction
CHON is a mnemonic acronym for the four most common elements in living organisms: carbon, hydrogen, oxygen, and nitrogen.
