Evaluation of pharmacokinetic properties and anaesthetic effects of propofol in a new perfluorohexyloctane (F6H8) emulsion in rats--A comparative study.
Propofol (2,6-diisopropylphenol) is a safe and widely used anaesthetic, but due to low water solubility and high lipophilicity a difficult compound to formulate. The solubility of propofol in the semifluorinated alkane perfluorohexyloctane (F6H8) is very high (>300 mg/ml). In the present work we investigate if a F6H8-based emulsion could be used as a new intravenous drug delivery system for propofol from a pharmacokinetic, pharmacodynamic and safety point of view. The pharmacokinetic parameters were evaluated after an intravenous bolus injection of either Disoprivan(®) or a F6H8-based propofol emulsion in Wistar rats. The onset and end of sedation after multiple dosings (5, 10 and 15 mg/kg bw) were examined. Clinical chemistry and histology were assessed. No significant difference was found for any of the pharmacokinetic parameters. No differences in the onset nor the end of sedation in the tested dosages could be detected. Histology scores revealed no differences. A slightly increased alanine aminotransferase (ALT) was measured after multiple application of the F6H8-propofol emulsion. In conclusion, the F6H8-propofol emulsion showed no significant different pharmacokinetics and sedation properties, compared to a commercial soy-based propofol emulsion. Further, no toxic effects could be detected on the F6H8 emulsion indicating it was a safe excipient in rats.

Lesson: Introduction to Hemodialysis

## Section 1: What is Hemodialysis?
Hemodialysis is a process that removes waste products and excess fluids from the blood of patients with kidney disease. It is a form of renal replacement therapy that helps maintain the proper balance of electrolytes, blood pressure, and fluid in the body.

## Section 2: Why is Hemodialysis Important?
Hemodialysis is important because it can help patients with kidney disease live longer, healthier lives. When the kidneys are not functioning properly, waste products and excess fluids can build up in the body, leading to serious health problems. Hemodialysis helps remove these substances, allowing the patient to feel better and reducing the risk of complications.

## Section 3: How does Hemodialysis work?
Hemodialysis works by filtering the blood through a special machine called a dialyzer. The dialyzer has two parts: one side contains a solution that helps remove waste products and excess fluids, while the other side contains a membrane that allows only healthy blood cells to pass through. As blood flows through the dialyzer, waste products and excess fluids are removed, and clean blood is returned to the body.

## Section 4: Who needs Hemodialysis?
Hemodialysis is typically used for patients with kidney disease who are no longer able to function properly. This can be due to a variety of reasons, such as diabetes, high blood pressure, or glomerulonephritis. In some cases, hemodialysis may also be used as a temporary measure to support the kidneys while they recover from an illness or injury.

## Section 5: Types of Hemodialysis
There are two main types of hemodialysis: in-center and home. In-center hemodialysis is performed at a specialized clinic, while home hemodialysis is performed at home using a portable dialysis machine. Both types of hemodialysis have their advantages and disadvantages, and the best option will depend on the individual patient's needs and preferences.

## Section 6: Risks and Complications
While hemodialysis can be lifesaving for patients with kidney disease, there are also risks and complications associated with the procedure. Some common risks include low blood pressure, infection, and bleeding. It is important for patients to work closely with their healthcare providers to monitor and manage these risks.

## Conclusion:
Hemodialysis is an important treatment for patients with kidney disease. By removing waste products and excess fluids from the blood, hemodialysis can help patients live longer, healthier lives. Understanding the basics of hemodialysis, who needs it, and the potential risks and complications is essential for anyone considering this treatment option.

text: Pre-exposure prophylaxis (PrEP) is a highly efficacious HIV prevention tool for men who have sex with men (MSM). Although research has identified MSM most likely to benefit from PrEP, the intervention's impact on population HIV incidence during real-world implementation is unknown. Identifying novel strategies to evaluate PrEP implementation and maximize the intervention's influence on community HIV transmission rates is critical to improve the cost-effectiveness of this expensive HIV prevention strategy. To address these needs, we will develop a method to evaluate PrEP implementation and identify optimal PrEP prioritization strategies that: (1) maximize clinical benefit to most-at-risk MSM, (2) are highly cost-effective, and (3) bring community HIV transmission to low levels. An innovative aspect of the proposed work is the use of a novel microsimulation technique known as agent-based modeling to evaluate a real-world, statewide PrEP implementation program. Our primary aim is to determine the demographic and behavioral characteristics of MSM who, if prescribed PrEP, would produce the largest decreases in community HIV incidence. Our primary hypothesis is that PrEP strategies prioritizing potential core transmitters (individuals who bridge infectious persons with lower-risk MSM populations) will be more effective at reducing HIV incidence and achieve greater cost-effectiveness than allocation strategies informed by current CDC guidelines. Second, we aim to increase the impact of Rhode Island's (RIs) first and only PrEP implementation program on community HIV transmission. Using the population-based microsimulation, we will evaluate the extent to which adherence, retention in care, and risk compensation (increased risk behavior) influence the program's projected impact on HIV incidence. Finally, we will compare the cost-effectiveness of current versus optimal PrEP implementation strategies. Our multidisciplinary team (with expertise in infectious disease medicine, epidemiology, and mathematical modeling) will leverage unprecedented access to population-based data sources from the state health department, an HIV care provider serving over 80% of the HIV-infected population in RI, the state's publicly-funded sexually transmitted diseases clinic, and the statewide PrEP program to parameterize high resolution, individual-based models. Our results will improve public health decision-making and clinical risk stratification schemes for predicting which MSM should be prioritized for PrEP. Finally, this exploratory R21 project will lay the groundwork for a statewide intervention to identify, engage, and retain potential core transmitters (and other high- risk MSM) in a PrEP program.

Lesson: Introduction to Pre-Exposure Prophylaxis (PrEP)

### Section 1: What is Pre-Exposure Prophylaxis (PrEP)?

PrEP is a medication that can be taken by people who are at high risk of getting HIV. It is a way to prevent HIV from being transmitted to others. The medication is taken daily and can reduce the risk of getting HIV from sex by up to 99%.

### Section 2: Who should take PrEP?

PrEP is recommended for people who are at high risk of getting HIV. This includes people who:

- Have had unprotected sex with someone who has HIV
- Have had more than one sexual partner in the past 6 months
- Have been diagnosed with another sexually transmitted infection (STI) in the past 6 months
- Use drugs and share needles
- Are a transgender woman who has sex with men
- Have been prescribed PrEP by a healthcare provider

### Section 3: How does PrEP work?

PrEP works by preventing HIV from entering the body's cells. When the virus enters the body, it attaches to a protein called CCR5. The virus then uses this protein to enter the cell and start reproducing. PrEP works by blocking the CCR5 protein, so the virus cannot enter the cell. This prevents the virus from multiplying and spreading throughout the body.

### Section 4: How effective is PrEP?

PrEP is highly effective when taken correctly. When used consistently, PrEP can reduce the risk of getting HIV from sex by up to 99%. However, it is essential to take PrEP every day, as missing doses can reduce its effectiveness.

### Section 5: What are the side effects of PrEP?

Some people may experience side effects when taking PrEP. These can include:

- Nausea
- Stomach pain
- Headache
- Weight loss
- Depression
- Decreased bone density

These side effects are usually mild and go away after a few weeks. It is essential to talk to a healthcare provider if side effects become severe or do not go away.

### Section 6: Where can I get PrEP?

PrEP is available by prescription from a healthcare provider. It is essential to talk to a healthcare provider about whether PrEP is right for you and how to get a prescription. Some health insurance plans cover the cost of PrEP, while others do not. There may also be programs available to help people afford PrEP.

### Conclusion:

In conclusion, PrEP is an effective HIV prevention tool for people at high risk of getting HIV. It is essential to talk to a healthcare provider about whether PrEP is right for you and how to get a prescription. PrEP works by blocking the CCR5 protein, preventing the virus from entering the body's cells. When taken consistently, PrEP can reduce the risk of getting HIV from sex by up to 99%.

1. Why did a distinguished-looking dude of about 60 and wearing a suit that had to cost over $5,000, get on the elevator with me and a few other folks this morning, hunt and hunt and hunt … and hunt the number buttons on his side of the elevator for a good ten seconds, conclude that the number 30 was missing from this particular side of the elevator (it wasn’t), walk over to the OTHER side of the elevator, easily find the number 30 that was “missing” from the other side, and then punch it with satisfaction, never realizing that the rest of us on the elevator were holding in some serious laughter. How is it that someone that stupid can make enough money to afford to wear a suit like that? It’s not like the numbers are on there randomly. 30 is between 29 and 31. Lord.

2. Why are there lots of attractive, smart, successful, cool women in the world that have trouble finding husbands, yet THIS woman was married to four different men at one time, including the cartoonist for the Trib, Randy Bish? She would just go to Vegas and guys would marry her.

I’m not trying to be mean, but the question had to be asked. She’s no Wendy Bell. And perhaps Randy’s latest joke IRS 1040 was a bit of an outlet for him? (click for larger image).

3. Why don’t I care who gets the slots license? I mean, if you put the casino in Station Square you will have a traffic nightmare, and if you put a casino next to the Science Center, that’s just stupid, but I really don’t care that much. I certainly don’t care as much as these people.

Lesson: Understanding Elevators and Numbers

Introduction:
Elevators are a common feature in many buildings, and they are designed to transport people between floors quickly and efficiently. However, sometimes people can behave strangely when using elevators, as seen in the example provided. This lesson will teach you about elevators and numbers to help you understand how they work and how to use them effectively.

Section 1: Understanding Elevators

Topic 1: How Elevators Work
- Elevators use a combination of hydraulics, electricity, and mechanical systems to move between floors.
- They have a control system that determines which floor to go to and how fast to move.
- There are different types of elevators, such as passenger elevators, freight elevators, and service elevators.

Topic 2: Etiquette in Elevators
- When entering an elevator, face the direction of travel and enter without stopping the door.
- If the elevator is crowded, let others off before boarding.
- Do not block the elevator doors from closing.
- Hold the door open button only if necessary.
- Be polite and courteous to others in the elevator.

Section 2: Understanding Numbers

Topic 1: Basic Arithmetic Operations
- Addition: adding two or more numbers together to find the sum.
- Subtraction: taking away one number from another to find the difference.
- Multiplication: repeating addition of the same number.
- Division: splitting a number into equal parts.

Topic 2: Fractions
- A fraction is a part of a whole.
- It consists of a numerator (the top number) and a denominator (the bottom number).
- To add, subtract, multiply, or divide fractions, the same denominator is required.
- To convert a fraction to a decimal, divide the numerator by the denominator.

Section 3: Practical Examples

Example 1: If an elevator travels at a speed of 10 meters per second, how long does it take to reach the 10th floor of a building with 20 floors?
- First, convert the floor number to meters: 10 meters/floor x 10 floors = 100 meters.
- Next, calculate the time it takes to reach the 10th floor: 10 meters/second x 100 meters / 10,000 seconds = 0.1 seconds.
- Therefore, it takes 0.1 seconds to reach the 10th floor.

Example 2: If an elevator has a capacity of 2,000 kg and a weight of 75 kg gets on, how much weight can it carry now?
- First, subtract the weight of the person from the total capacity: 2,000 kg - 75 kg = 1,925 kg.
- Therefore, the elevator can carry 1,925 kg now.

Conclusion:
In conclusion, understanding elevators and numbers is essential for navigating the world around us. By learning about how elevators work and basic arithmetic operations, we can apply these concepts to solve practical problems. Remember to follow elevator etiquette to make everyone's experience more pleasant. With these skills, you can apply them to new problems and situations.

Assessment of HIV-1 screening test sensitivities using serially diluted positive sera can give misleading results.
Three FDA licensed HIV-1 viral lysate and two nonlicensed recombinant antigen assays were used to evaluate six serially diluted plasma samples and 2 highly characterized seroconversion series. The sensitivity as measured by serial dilution did not necessarily correlate with the sensitivity as measured by seroconversion performance with the lysate and the recombinant assays. It is concluded that national licensing agencies should arrange to share seroconversion panels to evaluate accurately the sensitivity of new HIV-1 screening tests.

textbook:
Lesson: Evaluating the Sensitivity of HIV-1 Screening Tests

**Introduction**:
In this lesson, we will learn about the importance of evaluating the sensitivity of HIV-1 screening tests and how to do it correctly. We will also explore the differences between licensed and non-licensed assays and why it is essential to use seroconversion panels when evaluating test sensitivity.

**Section 1: Theoretical Concepts**:
- Sensitivity is a measure of how well a test can detect a disease or condition. In the context of HIV-1 screening tests, sensitivity refers to the ability of the test to correctly identify individuals who are infected with the virus.
- A seroconversion panel is a group of blood samples that are used to evaluate the performance of a new diagnostic test. These panels typically include samples from individuals who have recently been infected with HIV-1 and are at different stages of the infection.

**Section 2: Practical Examples**:
- Let's say we have a new HIV-1 screening test that we want to evaluate. We could use a seroconversion panel to determine the sensitivity of the test. We would give the test to a group of individuals who have recently been infected with HIV-1 and are at different stages of the infection. We would then compare the results of the test to the actual stage of infection for each individual to determine how well the test can detect the virus.
- However, if we only use serially diluted positive sera to evaluate the test sensitivity, we may get misleading results. This is because the sensitivity as measured by serial dilution does not necessarily correlate with the sensitivity as measured by seroconversion performance with the lysate and the recombinant assays.

**Section 3: Self-Debating Discussions**:
- Why is it essential to use seroconversion panels when evaluating the sensitivity of HIV-1 screening tests?
- What are some potential sources of error when evaluating the sensitivity of a test using serially diluted positive sera?
- How do licensed and non-licensed assays differ in their performance and sensitivity?

**Glossary**:
- Sensitivity: The ability of a test to correctly identify individuals who are infected with a disease or condition.
- Seroconversion panel: A group of blood samples used to evaluate the performance of a new diagnostic test.
- Licensed assay: A diagnostic test that has been approved by a national licensing agency, such as the FDA.
- Non-licensed assay: A diagnostic test that has not been approved by a national licensing agency.

**Conclusion**:
In this lesson, we learned about the importance of evaluating the sensitivity of HIV-1 screening tests and how to do it correctly. We also explored the differences between licensed and non-licensed assays and why it is essential to use seroconversion panels when evaluating test sensitivity. By understanding these concepts, we can ensure that our HIV-1 screening tests are accurate and effective in identifying individuals who are infected with the virus.

**Lesson: Muscles 101**

**Introduction**

In this lesson, we will learn about muscles - what they are, how they work, and why they are important. We will cover the following topics:

1. What are muscles?
2. How do muscles work?
3. Types of muscles
4. Importance of muscles
5. How to take care of your muscles

**Section 1: What are muscles?**

Muscles are specialized tissues in our body that help us move, maintain balance, and perform other physical activities. They are made up of cells called muscle fibers that contract and relax to produce movement.

**Section 2: How do muscles work?**

Muscles work by contracting and relaxing in response to messages sent from our brain. When we decide to move, our brain sends a signal to the muscles involved, telling them to contract. This contraction is caused by the sliding filament theory, where the actin and myosin filaments slide past each other, pulling the muscle fibers closer together and causing the muscle to shorten.

**Section 3: Types of muscles**

There are three types of muscles in our body: skeletal, smooth, and cardiac.

- Skeletal muscles are attached to bones and are responsible for voluntary movements like walking, running, and jumping.
- Smooth muscles are found in internal organs like the stomach, intestines, and blood vessels, and are responsible for involuntary movements like digestion and blood flow.
- Cardiac muscles are found in the heart and are responsible for pumping blood throughout the body.

**Section 4: Importance of muscles**

Muscles are important for several reasons:

- They allow us to move and perform physical activities.
- They help maintain our posture and balance.
- They generate heat, which helps regulate our body temperature.
- They produce hormones that are important for growth and development.

**Section 5: How to take care of your muscles**

To keep our muscles healthy and strong, we need to exercise regularly and eat a balanced diet that includes protein. Exercise helps build and maintain muscle mass, while protein is essential for muscle growth and repair.

**Conclusion**

In conclusion, muscles are an important part of our body that allow us to move and perform physical activities. By taking care of our muscles through regular exercise and a balanced diet, we can keep them healthy and strong.

Lesson: Introduction to Scoliosis Screening

Overview:
In this lesson, we will learn about scoliosis, its symptoms, and how to screen for it using a baseline scoliometer. We will also discuss the importance of early detection and referral to medical professionals.

Section 1: What is Scoliosis?

Scoliosis is an abnormal curvature of the spine that occurs most often during the growth spurt just before puberty. It is a common condition that affects approximately 3% of the population. The severity of scoliosis can range from mild to severe, and it can affect people of all ages.

Section 2: Symptoms of Scoliosis

The symptoms of scoliosis can vary depending on the severity of the curve. Some common symptoms include:

- Uneven shoulders or hips
- One shoulder blade that appears more prominent than the other
- A prominent or protruding spine
- Difficulty breathing or shortness of breath
- Pain or discomfort in the back or legs

Section 3: Screening for Scoliosis using a Baseline Scoliometer

A baseline scoliometer is a tool used to measure the angle of the spinal curve. It is a simple and non-invasive way to screen for scoliosis. Here are the steps to use a baseline scoliometer:

1. Ask the person to stand straight and breathe normally.
2. Position the scoliometer on the person's back, with one end of the tool resting on the lowest part of the shoulder blade and the other end resting on the top of the hip.
3. Ensure that the person is standing straight and not leaning forward or backward.
4. Read the angle of the spinal curve on the scoliometer. If the angle is greater than 5 degrees, it is recommended to refer the person to a medical professional for further evaluation.

Section 4: Importance of Early Detection and Referral

Early detection of scoliosis is crucial for successful treatment. If left untreated, scoliosis can worsen and lead to chronic pain, reduced mobility, and other health complications. Therefore, it is essential to screen for scoliosis regularly, especially during periods of rapid growth.

Conclusion:

In this lesson, we learned about scoliosis, its symptoms, and how to screen for it using a baseline scoliometer. We also discussed the importance of early detection and referral to medical professionals. By understanding the basics of scoliosis screening, we can help ensure that those affected receive the necessary treatment and care.


text: New Liquor Guide Page: Fermentation. All alcoholic beverages begin with fermentation, wherein yeast eats sugar and turns it into booze. Yay! Of course, it's not as neat and tidy as that. It can only be certain types of yeast (the Saccharomyces genus is most common) and certain types of sugar (simple sugars). And then there's the other stuff that fermentation creates, carbon dioxide and "congeners", which is a catchall term of other chemical compounds and substances that supply all the flavor, the good, the bad and the ugly.. Visit the Fermentation Page!

textbook:
Lesson: Fermentation 101

### Section 1: Introduction to Fermentation
Fermentation is a process used to convert simple sugars into alcohol and other chemical compounds. This process is essential for making alcoholic beverages like beer, wine, and spirits. In this lesson, we will learn about the basics of fermentation, including what it is, how it works, and why it is important.

### Section 2: How Fermentation Works
Fermentation is a biological process that occurs when yeast consumes sugar and produces alcohol, carbon dioxide, and other chemical compounds called congeners. This process takes place in two stages: the first stage is called alcoholic fermentation, while the second stage is called malolactic fermentation.

During alcoholic fermentation, yeast converts simple sugars into alcohol and carbon dioxide. This process is crucial for making beer, wine, and spirits. Malolactic fermentation, on the other hand, is a secondary fermentation process that occurs in some wines and cheeses. During this process, bacteria convert malic acid into lactic acid, which gives the final product its characteristic taste and texture.

### Section 3: Why Fermentation Matters
Fermentation is essential for making alcoholic beverages, but it also has other applications. For example, it is used in the production of bread, yogurt, sauerkraut, and other foods. Fermentation is also used in the production of biofuels, such as ethanol, which can be used as an alternative to gasoline.

### Glossary
- Fermentation: A biological process that occurs when yeast consumes sugar and produces alcohol, carbon dioxide, and other chemical compounds called congeners.
- Saccharomyces: A genus of yeast that is commonly used in fermentation processes.
- Congeners: Chemical compounds and substances that are produced during fermentation and contribute to the flavor of alcoholic beverages.

### Conclusion
In conclusion, fermentation is a vital process that has many applications in the food and beverage industry. By understanding the basics of fermentation, we can appreciate the science behind our favorite drinks and foods.

Q:

Using em and media queries to set relative font size

I'm looking to create a responsive design that can be used across all devices
My css contains the following:
@media screen and (min-width: 200px) and (max-width: 400px) {
    html {
        font-size: 8px;
    }
}

@media screen and (min-width: 400px) and (max-width: 800px) {
    html {
        font-size: 12px;
    }
}

@media screen and (min-width: 800px) and (max-width: 1600px) {
    html {
        font-size: 16px;
    }
}

#banner h3 {
    font-size: 3.125em;
    letter-spacing: 0.3125em;
    font-weight: 900;
    text-shadow: black 0 0.0753125em 0;
}

My understanding was that if I set the font-size at html level for different media sizes, then using em will ensure that it will be adjusted accordingly for each element.
So on my desktop my #banner h3 displays in 50px (16px * 3.125).
However, when I minimize my browser to 700px I was expecting that the h3 would reduce in size, but this is not happening.
This is my website: http://ec2-52-0-228-105.compute-1.amazonaws.com/
What am I missing here?

A:

You have a font-size: 14px; on your body. The body is a child element of html, that is why the font-size of the html is overwritten.
em refers to the font size of the nearest parent element with a font size, and in your case that is the body.
It seems that the body style comes from a wordpress theme or something. If you don't want to change the corresponding css file, you can change your code to overwrite the body:
@media screen and (min-width: 200px) and (max-width: 400px) {
    body {
        font-size: 8px !important;
    }
}

@media screen and (min-width: 400px) and (max-width: 800px) {
    body {
        font-size: 12px !important;
    }
}

@media screen and (min-width: 800px) and (max-width: 1600px) {
    body {
        font-size: 16px !important;
    }
}

Another possibility is to use rem instead of em, which is not 100% browser compatible: http://caniuse.com/#feat=rem

textbook:
Lesson: Using Em and Media Queries to Set Relative Font Size

Introduction:
In this lesson, we will learn about using em and media queries to set relative font size in responsive web design. We will cover the following sections:

1. Theoretical Concepts
2. Practical Examples
3. Real-World Scenarios
4. Glossary

Theoretical Concepts:
- Em is a unit of length used in CSS to define the size of an element. It is based on the font size of the parent element.
- Media queries are used to apply different styles to an element based on its size or other properties.

Practical Examples:
Let's say we want to create a responsive design for a website that can be used across all devices. We can use em and media queries to set relative font size for different screen sizes. For example:

```css
@media screen and (min-width: 200px) and (max-width: 400px) {
    h1 {
        font-size: 2em;
    }
}
@media screen and (min-width: 400px) and (max-width: 800px) {
    h1 {
        font-size: 3em;
    }
}
@media screen and (min-width: 800px) and (max-width: 1600px) {
    h1 {
        font-size: 4em;
    }
}
```

In this example, we are setting the font size of the h1 element to be 2em when the screen size is between 200px and 400px, 3em when the screen size is between 400px and 800px, and 4em when the screen size is between 800px and 1600px.

Real-World Scenarios:
Let's say we have a website with a banner that has a heading in it. We want the heading to be larger than the rest of the text on the page, so we use em to set the font size of the heading to be larger than the rest of the text. We also use media queries to adjust the font size of the heading based on the screen size.

```css
#banner h3 {
    font-size: 2em;
    letter-spacing: 0.3125em;
    font-weight: 900;
    text-shadow: black 0 0.0753125em 0;
}
```

In this example, we are setting the font size of the h3 element to be 2em, and we are using letter-spacing and font-weight to make the text more prominent. We are also using text-shadow to add a subtle shadow effect to the text.

Glossary:
- Em: A unit of length used in CSS to define the size of an element. It is based on the font size of the parent element.
- Media queries: Used to apply different styles to an element based on its size or other properties.

Conclusion:
In this lesson, we learned about using em and media queries to set relative font size in responsive web design. We covered the theoretical concepts, practical examples, and real-world scenarios of using em and media queries to set relative font size. We also created a glossary to define key terms. By applying these concepts, we can create responsive designs that can be used across all devices.
