- In what ways can you use aseptic technique principles in your daily life to preserve a healthy lifestyle, particularly in light of the CoVID-19 pandemic? Explain in four to five sentences.A COVID-19 test, which produce result in 10 minutes, has the following test characteristics. The test has a 95% sensitivity and a 95% specificity. The State of Massachusetts is in dilemma whether to test symptomatic individuals or the entire residents to decrease the spread of infection as depicted in the following two scenarios. Scenario A. The State of Massachusetts wants to administer the test on 40,000 individuals who will develop cough, fever and shortness of breath in the next 10 days to identify COVID-19 infected individuals and institute public health measures. The estimated prevalence of COVID-19 in this population is 750 per 1,000 population using a gold-standard test. Scenario B. The State of Massachusetts wants to administer the test to its entire COVID-19 uninfected population (6,750,000). The estimated prevalence of COVID-19 in this population is 5 per 1,000 population using a gold-standard test. Please help the State of Massachusetts by responding to the…Nicotinamide Adenine Dinucleotide (NAD) Assay (SIGMA Kit MAK037) analysis of tissue samples initially requires: centrifugation at 13,000g for 10min to homogenise tissue. centrifugation of 20mg of tissue at 2,000rpm with Extraction Buffer. freezing and thawing for 2 cycles of 20min before addition of Extraction Buffer. homogenization of PBS washed tissue with Extraction Buffer.
- Since molecular testing is the gold standard for detecting SARS-CoV-2 ,the causative agent of COVID-19, what do you think are special requirements of a COVID-19 testing laboratory aside from those required in a clinical laboratoryThe Covid-19 pandemic is a scalar problem. DiscussDescribe and explain the difference in results if the serial dilution step of the T4 bacteriophage suspension inour experiment was skipped (i.e., all of Step #3 of the procedures was skipped)? _________________________Current EventsThe Johnson and Johnson COVID-19 vaccine consists of inactivated adenovirus that has been altered to containgenetic information encoding SARS-CoV-2 surface spike proteins. The virus targets and delivers this geneticinformation to the cells of our respiratory tract, which produce benign SARS-CoV-2 surface spike proteins butare effective for training our immune system to defend us against SARS-CoV-2.Based on this information and your knowledge of viruses in general, could T4 bacteriophage be used in place of
- discuss the adoption (recommended or required) of the use of wearing a mask during this COVID-19 pandemic environment.Choose a range of ODe00 from the data set that can assure a good correlation of viable cell 600 count with optical density. CFU/mL OD. 600 1 X 103 1х 108 0.1 1.75 X 108 0.2 1.9 x 108 0.4 4 x 108 0.7 9 x 108 0.71 Best OD600 range: Correlation coefficient (best fit): Regression equation (best fit):It has been found that blood types (ABO) affect the COVID-19 infection rate and the disease severity. Blood type A individuals are more likely to be infected and more likely to suffer from severe disease. Blood type O individuals seem to be less affected. Outline possible reasons for this. Note: So far, no studies have been published to conclusively answer this question, so there are no "wrong" answers here. The point is to come up with some ideas/hypotheses based on your knowledge about the molecular basis of blood types and what the consequences might be in relation to viral infections.
- explain the most likely steps of what might happen inside a MDA-MB-231 cell after it is exposed to UV light.One of the causes of morbidity for the Zika Virus is Guillain-Barré Syndrome, an immune attack of nerve cells. One possible mechanism for this is the virus's interference with normal immune function. In HIV the virus uses the CD4 receptor to enter T-cells. To assess if this might be a possibility in Zika infections BLAST the CD4 Reference Sequence (NG 027688.1) against the Zika Virus (taxid:64320) choosing "blastn" under Program Selection (select all that apply): O None of the recovered sequences have identities of greater than 80%. O Multiple Zika virus isolates are observed to have E-values of less than 0.02. O High scoring BLAST hits are observed in Zika virus isolates from humans, mosquitoes, and monkeys. O The BLAST hits return a partial cds collected in Uganda in 1947 - isolate Uganda1947.In what ways can you apply the principles of aseptic technique in your everyday life tomaintain a healthy lifestyle, especially in this time of CoVID-19 pandemic?
