Background: The only technique that can produce noninvasive skin tightening is nonablative radiofrequency (NARF). However, a key drawback of this method is that it causes considerable discomfort throughout the treatment. to produce skin contraction leading to the lifting of eyebrows and/or improvement of lower face and neck skin laxity using fluences below pain levels.
A less painful option was evaluated using a novel nonablative medical device called Titan (Cutera, Inc., Brisbane, CA, USA), which can achieve fluences substantially lower than those available with NARF. 25 patients were treated, using the nonablative radiofrequency. Prior to the treatment, a few days, a few weeks, and up to 12 months later, standardized pictures were taken.
Results: 22 out of 25 patients had immediate changes after nonablative radiofrequency. Photos underwent analysis, and it was discovered that the initial improvement remained during the follow-up time.

Near [corrected] painless, nonablative, immediate skin contraction induced by low-fluence irradiation with new infrared device: a report of 25 patients
Answer:
The Harrison Act of 1914, passed by the United States Congress, made the distribution of nonmedical drugs a crime.
The current agency charged with enforcing this act is the Drug Enforcement Agency (DEA).
Explanation:
The agency currently charged with enforcing its provisions is Drug Enforcement Agency (DEA), which seeks to counteract illicit manufacture, possession, and consumption. Unlike other drug enforcement agencies, DEA does not pursue drug possession cases unless they involve DEA-protected nonmedical substances.
The Drug Enforcement Agency (DEA) is charged with enforcing this act, sometimes known as the “drug kingpin” statute. The Drug Enforcement Agency (DEA) is the enforcement arm of the US Department of Justice.

Answer:
-Because epinephrine can bind to different receptors and can activate different signalling pathways with varying responses.
Explanation:
Epinephrine is a hormone, synthezied and secreted by adrenal gland during stress conditions. Epinephrine leads to vasoconstriction of many blood vessels, while it leads to dilation of blood vessels in liver and skeletal muscle cells.
This is because epinephrine has ability to bind with both alpha- and beta-adrenergic receptors, which are present in different target cells or organs. As both receptors involve different signalling pathways which leads to generation of different responses on target organs or tissues.
Thus, epinephrine shows different responses in different target organs.
Answer:
Letter E
Explanation:
I truly wouldn't take this advice from me; I'm a high school freshman who's dream is to become a surgical nurse. However, letter E is the most logical. You wouldn't order an x-ray first. You definitely wouldn't prescribe pt. You wouldn't have the time to do the research if the patient is in pain and if it's limp. And if the leg is limp, then the patient might not be able to feel it. If they can, then the ortho specialist can ask questions about the pain.
Answer:
3432 Hz.
Explanation:
The resonant frequency of the canal can be calculated as follows:
f = v/ 4l
Here, f is frequency, v is velocity of sound and l is the pipe length.
l = 2.5 cm = 0.025m and v = 343.2m/s.
Put these values to find the resonant frequency
f = 343.2 / 4 * 0.025.
f = 3432 Hz.
Thus, the answer is 3432 Hz.
