Final Blog Entry: Reflection

When I first enrolled in this course, I was not sure what to expect. After less than a week of being in Professor Greer’s class, I knew that I would learn an incredible amount. First and foremost, my favorite experiences in this class were the two labs that we did. Learning how to make aspirin and soap from scratch was very cool and insightful. I had no clue that soap was able to be made from simple fats and that aspirin requires such specificity while being created to ensure edibility. I felt like an actual scientist and I was able to learn that in the real world it can take hundreds of thousands of tries to figure out how to achieve a specific desired outcome.

While in the class, I found it difficult to work on two projects at the same time; however, towards the end, I felt incredibly accomplished. Luckily, the fact that these two projects were in groups made them a bit less stressful due to split responsibilities. The BioBlitz and Healthcare Innovation projects truly enabled me to learn how to do proper scientific research, create an experiment from scratch, work in groups for a prolonged period of time, and practice my presentation skills.

Additionally, I really appreciated and enjoyed the side-lectures that both Jake and Dr. Greer held throughout the course. Jake presented slideshows on doing scientific research, creating proper citations, writing lab reports, and creating abstracts, all of which were very useful. Meanwhile, Dr. Greer presented more fun slideshows and lab demonstrations, such as how certain drugs react to the human body.

This course was very insightful, fun, hands-on, and eye-opening. I learned things that I would have never expected to learn. Most importantly, I truly felt like a scientist through all of our projects and labs, and I was eager to participate each day due to the fact that Jake and Dr. Greer fostered such a strong and positive environment for learning. Thank you both very much!

Blog Post 2 – Aspirin Lab

I genuinely enjoyed doing the “Synthesis of Aspirin” lab. This was my first time creating a drug from scratch, which was a rather interesting experience. While Yina and I were working on the lab, we made sure that each measurement was absolutely perfect. Our goal was to see a beautiful orange color in the end with absolutely no trace of purple. Although we thought everything was incredibly accurate, our end result showed us that there was a super tiny bit of salicylic acid in our aspirin, which was evident by the small tint of purple in our solution.

This lab made me reflect on a couple of things we discussed throughout the semester – mainly experimental design, and how both trial & error and precise measurements are necessary in order to get proper end results. We spoke about how it took many years for the creation of aspirin to actually take place; there were numerous failed attempts, which is actually something that I witnessed myself. It’s crazy to think how scientists try over and over again until they get their desired outcome. I personally do not have the tenacity to restart an experiment hundreds of times, so I truly commend scientists for doing what they do. Overall, I would definitely try this lab a few more times, or at least until I get that perfect orange color to prove that I can create consumable aspirin.

According to the article, although 2/3 of the world’s population will live in urban areas by 2025, it is vital to keep biodiversity and plant life protected for the sake of our future generations to thrive on this planet.

 

HI Project Proposal – Refrigeration Cube

Group Members: Mark, Karishma, AJ

        Emergency rooms across America come face to face with limb amputations and cases with detached body parts caused by household accidents. While treatment of such cases has progressed due to evolving medical technology, a large factor in these cases is the handling of the detached body part from the site of the accident to the hospital. Many people are unaware of the right procedure to follow in such cases and thus, choose to ice the body part while waiting for appropriate medical care. However, this method actually damages the limb further and decreases the chances of successful reattachment. The best practice would be to first disinfect the limb and then cool it within measure, never putting it directly in contact with ice. Furthermore, when ambulances do arrive on the scene of the accident, they also lack best practices to handle the body part. Our proposed healthcare innovation is a refrigeration box that has two compartments: one to disinfect the body part and the other to keep it at an optimal temperature until appropriate medical care is available. The settings of the box would allow you to control the temperature of the box in order to adjust it for different body parts.

        Our group was inspired not only by our personal experiences with cases dealing with bad injuries, but also because we have done extensive research to come to the conclusion that the majority of everyday civilians don’t know what to do when confronted with this issue, and even worse, there hasn’t been enough developed technology to make this treatment process efficient yet safe. We also knew that the reattachment of limbs was greatly affected by the process of taking care of the severed appendages, arteries, and veins. As stated by Elana Glowatz, “No matter where surgeons attach an errant limb, the process involves restoring blood flow in the appendage by re-connecting the arteries, through which blood enters the body part, and the veins, through which it leaves.” (Glowatz 2018) Overall, we confirmed a lot about what we already knew on the background of our healthcare innovation, but also learned a lot of new interesting facts that enabled us to take into account the temperature we wanted to set inside our box, the different dimensions, as well as the different target groups we wanted to advertise too.

        With regards to the functionality of the product, as stated earlier, we plan for it to be a refrigeration cube that is divided into two sections: the disinfection side and the preservation side. The purpose of this cube is to enable the severed body part to maintain future functionality while being detached from the body. By using the refrigeration cube, there will potentially be a much higher success rate of attaching disjointed limbs, compared to the old method of separately disinfecting the body part, putting it in a bag, and then placing it on ice. Our target market for this product was originally predominantly for ambulances and hospitals. Although this is still our main avenue, we plan to market to the military as well. There are many cases of individuals losing limbs, and we believe our product will be able to help in the process of re-attaching those limbs more properly and efficiently.

        Overall, as we create 3D models of our product and do further research surrounding the technicals and necessity of this product, we are certain that we can create a useful refrigeration cube. With proper research and development, we will be able to find the ideal target market and turn our idea into a marketable, successful, and helpful product.

The Author of this popular article is Elizabeth Cohen, CNN’s Senior Medical Correspondent. Cohen is the lead reporter for CNN’s Health, Medical, and Wellness Unit. In addition to numerous articles, Cohen is also the author of several novels regarding medical advancements. This article touches upon the procedures one should follow in case of a freak-accident that led to a severed part of the body. Cohen ranges from fingers and toes to teeth and eyeballs. The main point of the article, which connects to our innovation, is that a severed finger or toe must never touch ice; it should be properly treated in order to stay intact and be capable of being reattached to the human body. This article will help us express both procedures that should and should not be done in the event of a freak-accident.

It also goes into detail about the common method of placing the amputated body part in a waterproof bag, then putting the bag in ice. Lastly, the author states that it is imperative to NOT allow the body part to touch ice or dry ice, as it can result in thermal necrosis.

BioBlitz Worksheet – Mark, Karishma, AJ

Group Members: Mark Kashani, Karishma Malhotra, AJ Johnson

1. What is the final version of the question you are interested in asking?

How does the variation of plant life in NYC Parks affect each respective environment?

2. List some keywords to use when searching for related scientific literature. Be specific!

Ecosystem, air quality, water quality (acidity), variation, germination, roots/taproots, chlorophyll, chloroplast

3. Where will your data come from? Do you need to collect new data? Please describe.

Our data will primarily come from the BioBlitz research that has been conducted over the past few years in the various NYC parks. The BioBlitz observations will enable us to understand what fauna and flora are found in the parks; however, we will be doing some outside research to figure out exactly how the specific plants found in these areas affect the surrounding environment.

4. What will you be measuring or comparing? What are the dependent and independent variables?

We will be measuring the characteristics of certain plants in different parks, then comparing those characteristics to see the effects on the surrounding environment. The independent variables will be the plants, and their characteristics, found throughout NYC Parks. Meanwhile, the dependent variables will be the surrounding air quality, water quality, animals, and insects with respect to plant life.

5. Please make a list of your methods. If you are using existing BioBlitz data, you do not need to describe those data collection methods on this worksheet, but you do need to describe how you are extracting the relevant data from the entire BioBlitz data set.

  1. Begin by analyzing our own plant observations from BioBlitz (which we have a picture of), and cross-reference them with other plant observations to find the most abundant species
  2. Then use previous BioBlitz data to collect information on plant life in other NYC Parks
  3. Organize our data to portray the 5 most abundant plant species in each park
  4. Then go back to the BioBlitz Data Base, including observations from this year, and write down observations about air quality, water quality, animal life, and insect life
  5. Lastly, use outside research to connect how these specific plants found in the parks impact their surrounding environment and lead to the outcomes shown by the dependent variables

6. Why is this question interesting to you? Why should others care about this topic?

This research question is of interest to our group because after visiting Inwood Hill Park, we realized the variation of plant life in each park across NYC and the major impact it had on each environment it was placed in. Others should share this same concern because they may live in many similar environments and there may be plant life in our experiment that can improve the quality of their environment.

Device that assists slowly developing infants with walking

My first cousin, who will be 3 years old in November, has been developing at an unusually slow rate. Her main issues are that she has had trouble walking and forming words. After almost a year of therapy, she finally began walking. I propose a device that will stimulate and encourage infants to begin walking as early as possible. This device will be interactive, easy to set up and use, and will help with both speaking and walking because of the innovative voice reinforcement that will be built into the product.

Blog Entry 1 – Mark Kashani

If I had to author a popular article based on a scientific journal, there would be quite a few things that I would be sure to include in order to make it appealing to the general audience while maintaining its scientific accuracy. First and foremost, I would absolutely make sure to include quotes from the author(s) of the scientific journal. Adding this enables the reader of the popular article to gain insight into what went on in the mind of the original author while conducting his or her experiment, and as a whole, I believe that it actually increases the credibility of the popular article. Second, I think it is important to make connections of the study at-hand to things of a light-hearted nature, such as pop culture. By doing this, the reader is able to relate more to the article, and the references may be able to help the reader understand the journal to a greater extent.

Something interesting I noticed is that a large sum of popular articles did not contain a single graph from their respective scientific journal – not even a simple one. This leads into my third point, which is that I would add a couple of simple graphs and images from the scientific journal in order to make the piece more colorful, and actually quantify some statistics from the journal. Lastly, and arguably most importantly, I would do my best to avoid any bias in my writing. Not only can taking a specific argumentative standpoint ruin the credibility of one’s piece, it can also make it unappealing due to lack of factual information, which may cause the reader to easily lose interest. All in all, the two most important questions to ask yourself while writing a popular article are “will the reader want to continue reading this?” And “Is everything 100% accurate?” With these questions in mind, a unique and credible popular article is sure to be produced!

EpiPens and School Nurses

Throughout the United States, one of the several major challenges that school nurses have to deal with is that each school district has a distinct action plan in case of emergency, which may contradict the health care provider’s plan for a given student; this plan set by health care providers may also conflict with the American Academy of Asthma, Allergy and Immunology Guidelines, which may expose the dangerous risk of anaphylaxis if the patient is not treated in a timely manner. Recently, numerous studies have shown that the inadequate treatment of these allergic reactions with epinephrine can be a safety concern (Boyce et al., 2010; Carlisle et al., 2010; Fleischer et al., 2012; Nowak-Wegrzyn, 2021b). Due to the fact that school nurses are in the position in which they have direct communication with both parents and health care providers, they have an increased potential to keep students safe under their care (Wahl et al. 2015, 97).
