Cynthia, a 53-year-old female presented to the emergency room due to feeling constantly tired, hungry, thirsty, and with frequent urination. Her past medical history is significant for cirrhosis and end-stage kidney disease. Physical examination had revealed yellowish discoloration to the skin, multiple bruises, bilateral edema, and weakness lasting more than three weeks. Laboratory tests were ordered (results provided below) after which she was prescribed metformin and informed to contact a doctor if she starts experiencing nausea, vomiting, fast breathing, and/or lethargy, as metformin has been known to cause metabolic acidosis. Complete Blood Count (CBC) Sodium 126 mEq/L Glucose 220 mmol/L Calcium 7.1 mg/dl Red blood cell count 3.9 cells/ul Iron 40 mcg/dL Albumin 2.5 g/dl Vitals Blood pressure 92/64 mmHg Hormone Panel Renin Low ADH Elevated Aldosterone Low Vitamins Vit D Low Vit K Low Vit E Low Vit A Low Urine and Stool Sample Stool color Gray Stool content Increase fat content Urine color Clear Complete Blood Count (CBC) Glucose Present Answer the following questions regarding Cynthia’s case: What hormone is not functioning properly causing Cynthia’s glucose levels to be abnormal? Furthermore, explain in depth how this hormone regulates blood glucose levels. What other hormone(s) are responsible for maintaining normal glucose levels? Explain in depth how they work. Explain why Cynthia is presenting with excessive thirst (polydipsia), tiredness and hunger (polyphagia), and frequent urination (polyuria). Explain why Cynthia is experiencing hypotension. How does the body and its various organ systems bring the blood pressure back towards homeostasis? What do you expect Cynthia’s heart rate and end-diastolic volume (EDV) to be (elevated, normal, or low) and justify your expectation with cardiovascular formulas such as cardiac output (CO) and stroke volume (SV). What is the importance of iron in the body and the consequence of it being 40 mcg/dL? Explain in detail what gluconeogenesis is and where in the body it occurs? Knowing that gluconeogenesis helps maintain blood glucose level, what is the effect of metformin on the management of diabetes mellitus type 2? Looking at Cynthia’s albumin levels, what effect does it have on her (a) blood osmolarity (b) glomerular filtration rate (GFR) and (c) urine volume? Explain how glucose is normally reabsorbed by the kidneys? What is happening in Cynthia’s kidneys resulting in glucosuria and what effect does glucosuria have on her blood pressure? If Cynthia ends up developing metabolic acidosis, what would the levels of her pH, CO2, and HCO3 be in the blood? Furthermore, how would the body compensate and address both renal and respiratory compensation (optional: show the compensation via a flow chart)?

Assignment Instructions:
Let’s practice using the scientific method: I want to know which sunscreen is the best sunscreen to use to protect from harmful UV rays. I have 5 different types/brands to try. Thankfully, there are beads that I can purchase that react to UV light.  They are clear until exposed to UV light, then they turn bright colors.  In my experimental setup, I will have 6 groups. One group will be the control group and will consist of only beads and no sunscreen. The other 5 groups will consist of beads and one type of sunscreen applied to the beads.
To do:
Post to the Discussion Board and include the four components below:
Name the independent variable in my example UV bead experiment.
Name the dependent variable in my example UV bead experiment.
Name one controlled or standard variable in my example UV bead experiment.
Describe an experimental design and setup to test a product of your choice (and not the UV bead experiment).  Make sure to identify the independent, dependent, and standard variables.  Comment on one of your classmate’s experimental setup.  You can identify another control, standard variable, or possible improvement to their design.

j’aimerais que vous réalisez en français sans plagiat en 1 pages le résumé de mon mémoire de master, ensuite faites une interprétation et discussion de la partie résultat avec des références bibliographies récentes dans le texte et à la fin du document, en fin vous ferez une conclusion générale du projet de mémoire

Description of Pathology:
Start the paper on a new page.
In this section, you will describe the pathology (statistics about it, background information, etc.). Give as much information as you can about it but be sure it is relevant information and not just filler. It should be a comprehensive introductory section of the condition in one to two paragraphs.
Normal anatomy of the major body system affected: In this section, you will describe what is considered normal anatomy for your particular pathophysiology. For example, if you are discussing a disease related to the brain, explain what is normal for the brain from an anatomical standpoint. You should show comprehensive knowledge of the fundamental concepts and communicate information using scientific vocabulary. There should be little to no discussion of the condition itself in this section.
Normal physiology of the major body system affected: In this section, you will be discussing physiology. Keep in mind that when describing physiology, it isn’t enough to merely provide a list of functions of the body system (Ex: Neurons send signals throughout the body), instead, you need to be able to describe how it does it. The how is the physiology. There should be little to no discussion of the condition itself in this section
Mechanism of Pathophysiology: This section is likely going to be the most in-depth and longest section. In this section, you will explain your particular pathophysiology from a scientific standpoint. In the previous two sections, you explained what is considered normal, in this section, you should describe what the pathophysiology is doing that is causing these issues, how the normal anatomy & physiology is affected/different in a person with your condition. You should show a thorough understanding of the anatomical and physiological changes contributing to the disease. Some good keywords to search for when doing your research might be “Pathology of __________”, Pathophysiology of __________.”
Prevention: In this section, you will explain how your pathophysiology could be prevented. This should outline possible prevention protocols, or clearly indicate if none is available based on the current scientific literature.
Treatment: In this section, you will explain how your pathophysiology is commonly treated. Provide possible treatment protocols for the condition based on current scientific literature. Be sure to bring in nursing relevant information and how you might be involved in the treatment of the condition.
Conclusion: Finally you should summarize your findings. All good research papers should include a conclusion where you wrap up and summarize all of the important points made in your paper.
References:
As with the Title page, this should be a separate page by itself.
All references should be included in correct and complete APA format.
All references must be cited appropriately in the paper using APA-style in-text citations.
A minimum of three reputable sources are required for this assignment.

These are the instructions for this assignment
Step 1: Search for a news article on the Genetics of Behavior on ScienceDaily or ScienceNews. The article must have been published between January 2023 and May 2024. Summarize the article and tell us what caught your attention in it.
You can summarize the abstract in ChatGPT. If you do, you must include a screenshot of the prompt and the output and include an analysis of whether ChatGPT did a good job summarizing the main points.
If you summarize in your own words, you don’t need to do this.
However, if you say you summarized in your own words but didn’t (I’ve been pretty good at detecting this), I will give you a 10/100 on this assignment. You must include the reference in APA style.”
Reference in APA style:
AuthorLastName, A. A., & AuthorLastName, B. B. (Year). Title of the article. Journal Name, Volume(Issue), Page range. [Link to the article]
Analysis of ChatGPT’s summary:
[Insert analysis here]
[Insert screenshot of the prompt and the output here]
Step 2: Come back to find a peer who found an article on a similar topic as yours (e.g., sleep and genetics, addiction and genetics, autism and genetics, etc). Highlight similarities with the news article you found. If you post Step 1 on Friday, May 24, or Saturday, May 25, chances are that your peers might miss it. For this reason, you need to comment to four of your classmates.
Step 3: Answer the questions or reply to the comments you received.
Step 4: Thank your peer for answering the question or replying to your comment.

Research question: 
1.) How do mutations affecting nuclear envelope proteins contribute to diseases like laminopathies?
2.) How do mutations in the emerin nuclear protein cause Emery-Dreifuss Muscular Dystrophy?
one short paper but it’s due step by step. 

Before You Start:
To prepare for this assignment, I recommend that you:
Read these directions carefully.
Read the BIOL180 Mini-Presentation Grading Criteria.pdf. The grading criteria is a detailed evaluation that I will use to assess your performance. It also will help you understand what is expected of you as you prepare your assignment.
Use your own words (paraphrase). For help with paraphrasing, please review the ‘Quoting and Paraphrasing’ help in the Trefry Library Writing@APUS Center. 
Note that your Turnitin report similarity score should be under 20% (not including references) and free of paraphrasing issues. Review the color-flagged text on your report, fix any issues, and resubmit again before the deadline (this assignment is set to unlimited submissions until the deadline).
Note that less than 10% of your work should contain direct quotes.
Email me with any questions!
Assignment Instructions: The topic of your Course Project will be any one species of organism (e.g., a microorganism, plant, fungus, animal, etc.). Choose only one that interests you, as this will be the topic used for all Course Project steps and assessments throughout the term.
Keep the following in mind:
The topic of the course project will be any species native to your area or one that interests you. The organism should come from one of the four major kingdoms (Protist, Fungus, Plant, or Animal) and be indigenous to the area in which you reside. The organism should not be a domesticated pet, farm animal, houseplant, human, etc., but rather a wild species native to the local area where you live or one that you find interesting but may not be able to directly observe (e.g., great white shark). You will be researching details of your organism in the wild, not as a plant cultivar or as an animal may live as a pet or captive zoo inhabitant, as these conditions are not wild.  If possible, try to select a different species than your classmates. However, it is okay if more than one classmate selects the same organism; I want you to be interested and excited about what you will be researching!
Mini-Presentation requirements:
Your presentation will be submitted as an audio-narrated PowerPoint, narrated by you, the student. You cannot use “text-to-speech” programs or technologies that do the narration for you unless noted as an approved accommodation in a current DSA letter you have furnished to me. For instructions on how to create audio narration in PowerPoint, see the following link: Record a Slide Show With Narration. Audio narration is a requirement!
Familiarize yourself with the BIOL180 Course Project Guide.pdf.
Create a 3-4-slide audio-narrated PowerPoint presentation to include the following:
A title slide with your name, date, class name, instructor name, and project topic
Content slide(s) to include:
The common and scientific name of your organism. Please see this link to help with scientific names if needed: How To Write Scientific Names of Organisms
Where you observed your organism (country, state, park, zoo, etc.)
A brief discussion on why you chose your organism
If possible, a picture and/or video of you safely observing your species in the field. If not possible, search the Internet for an image (and remember to cite your source for the image) in a typical habitat.
Reference slide for all source material and images used within the mini-presentation
[Recall that Wikipedia is not considered a credible source for our purposes and should not be used in class.]
APA in-text citation and reference formatting is optional for this assignment. However, it will be required for subsequent assignments.
*Writing Expectations:  Apply scientific concepts and use scientific terminology correctly.  Utilize proper spelling, grammar, and punctuation. 
For help with pronunciation, see this link: Collins Online Dictionary.

For this order you need to write one short paper on Nucleus 
here is research question: 1.) How do mutations affecting nuclear envelope proteins contribute to diseases like laminopathies?
2.) How do mutations in the emerin nuclear protein cause Emery-Dreifuss Muscular Dystrophy?
But this paper has multiple mini-examples: First, you have to select the primary and review article, then need to make paper outline. so this paper is due step by step but it’s only one short paper. 
I will send you that step by step when it will come. I have done 1st part. I am going to attach the part 2 here, I will attach more as we go through. 
I also attached schedule to make it more clear.
