OleMash [197]

Those pores and skin spots and growths are due to melanocyte cells inside the pores and skin. Melanocytes are the cells that produce melanin, the substance that offers coloration (pigment) to the pores and skin cancers

A visual self-exam by using the affected person and a scientific examination by way of the health care company may be used to screen for pores and skin cancers. all through a pores and skin examination a health practitioner or nurse tests the skin for moles, birthmarks, or other pigmented areas that look bizarre in color, length, form, or texture.

Communicate with your health practitioner in case you observe modifications in your pores and skin which include a brand new growth, a sore that doesn't heal, an exchange in a vintage boom, or any of the A-B-C-D-Es of melanoma. A trade to your skin is the most not unusual signal of skin cancer. this will be a brand new increase, a sore that does not heal, or an alternate in a mole.

Which of the following reactions with covalently closed, circular DNA (cccDNA) does NOT result in a new linking number? A. incub
alisha [4.7K]

Answer:

Okay

Explanation:

Human topoisomerase I plays an important role in removing positive DNA supercoils that accumulate ahead of replication forks. It also is the target for camptothecin-based anticancer drugs that act by increasing levels of topoisomerase I-mediated DNA scission. Evidence suggests that cleavage events most likely to generate permanent genomic damage are those that occur ahead of DNA tracking systems. Therefore, it is important to characterize the ability of topoisomerase I to cleave positively supercoiled DNA. Results confirm that the human enzyme maintains higher levels of cleavage with positively as opposed to negatively supercoiled substrates in the absence or presence of anticancer drugs. Enhanced drug efficacy on positively supercoiled DNA is due primarily to an increase in baseline levels of cleavage. Sites of topoisomerase I-mediated DNA cleavage do not appear to be affected by supercoil geometry. However, rates of ligation are slower with positively supercoiled substrates. Finally, intercalators enhance topoisomerase I-mediated cleavage of negatively supercoiled substrates but not positively supercoiled or linear DNA. We suggest that these compounds act by altering the perceived topological state of the double helix, making underwound DNA appear to be overwound to the enzyme, and propose that these compounds be referred to as ‘topological poisons of topoisomerase I’

adoni [48]

Flow rate needed to deliver the dose 250 ml bag of NS with 1g of Kefzol is 41.6gtt/min.

What is kefzol?

Cefazolin or kefzol is an antibiotic used to treat a wide variety of bacterial infections. It may also be used before and during certain surgeries to help prevent infection. This medication is known as a cephalosporin antibiotic. It works by stopping the growth of bacteria.

Given data:

Volume = 250ml

time = 60 mins

drop factor = 10gtt/min

Volume (mL)/ Time (min)x Drop Factor = Y (Flow Rate)

250ml/60 mins×10gtt/min = Y

Y = 41.6 gtts/min
