Lesson Title: Reverse Osmosis and Electrodeionization in Water Treatment

Introduction:
Water is an essential component of life, and access to clean water is crucial for human health and well-being. In many industries, including power generation, military operations, medicine, electronics, and machinery, the need for pure water is critical. Reverse osmosis (RO) and electrodeionization (EDI) are two technologies used to produce ultrapure water with high conductivity. This lesson will focus on the principles of RO and EDI, the process systems used in these technologies, and their applications in various industries.

Section 1: Principles of Reverse Osmosis and Electrodeionization

Reverse osmosis is a process that uses pressure to force water molecules through a semipermeable membrane, leaving impurities behind. The membrane allows water molecules to pass through but blocks larger particles such as salts, ions, and other contaminants. EDI, on the other hand, is an electrically-assisted version of deionization, which uses electricity to remove ions from water. Both technologies are used to produce ultrapure water with high conductivity.

Section 2: Process Systems Used in Reverse Osmosis and Electrodeionization

There are several process systems used in RO and EDI water treatment, including American Water Yezone GE, EXL, Ionpure, and Kanpur Canadian technology. These systems use two RO + EDI technologies, high degrees of automation, and water quality monitoring systems to ensure that the produced water meets the required specifications.

Section 3: Applications of Reverse Osmosis and Electrodeionization in Various Industries

The high-quality water produced by RO and EDI technologies has a wide range of applications in various industries. In power generation, ultrapure water is used to cool turbines and generators, ensuring optimal performance and efficiency. In medicine, pure water is used for sterilization and other medical procedures. In electronics, pure water is used to clean and test electronic components. In machinery, pure water is used as a coolant and lubricant.

Conclusion:
Understanding the principles of RO and EDI, the process systems used in these technologies, and their applications in various industries is essential for anyone interested in pursuing a career in water treatment or related fields. By mastering these concepts, you will be able to apply your skills to new problems and contribute to the development of innovative solutions in water treatment.

text: Abstract. To achieve very high data rates (>109 bits/s) in optical data storage systems it is necessary to employ a large number of laser beams for parallel read–write–erase operations. Bringing all these beams to diffraction-limited focus with a high-numerical-aperture objective lens (while maintaining focus and tracking) requires techniques that are fundamentally different from those that are currently practiced in the field of optical data storage. We present two possible solutions to the problem of designing an objective lens for such systems, one involving an array of high-quality lenslets and the other based on a single, high-numerical-aperture annular-field-of-view conventional lens. Both approaches have advantages and disadvantages, on which we elaborate in the course of our discussions.. © 1999 Optical Society of AmericaFull Article | PDF Article

Lesson: Optical Data Storage Systems

Introduction:
Optical data storage systems are used to store information on optical media such as CDs, DVDs, and Blu-ray discs. These systems use laser beams to read and write data on the surface of the disc. In this lesson, we will learn about the challenges of achieving high data rates in optical data storage systems and the different techniques used to address these challenges.

Core Value:
To achieve very high data rates in optical data storage systems, it is necessary to employ a large number of laser beams for parallel read–write–erase operations. This requires techniques that are fundamentally different from those currently practiced in the field of optical data storage.

Section 1: Challenges of Achieving High Data Rates in Optical Data Storage Systems

Topic 1: Parallel Operations
One of the main challenges in achieving high data rates in optical data storage systems is the need for parallel operations. This means that multiple laser beams must be used simultaneously to read and write data on the disc.

Topic 2: Diffraction-Limited Focus
Another challenge is maintaining a diffraction-limited focus for all the laser beams. This requires an objective lens with a high numerical aperture (NA).

Topic 3: Maintaining Focus and Tracking
Maintaining focus and tracking for all the laser beams while using a high-numerical-aperture objective lens is also a challenge. Current techniques used in optical data storage systems may not be sufficient for this task.

Section 2: Possible Solutions for Designing an Objective Lens for Optical Data Storage Systems

Topic 1: Array of High-Quality Lenslets
One possible solution for designing an objective lens for optical data storage systems is to use an array of high-quality lenslets. Each lenslet would have a low numerical aperture, which would allow for better control of the laser beams and maintaining focus and tracking.

Topic 2: Single, High-Numerical-Aperture Annular-Field-of-View Conventional Lens
Another possible solution is to use a single, high-numerical-aperture annular-field-of-view conventional lens. This type of lens would provide a larger depth of focus, making it easier to maintain focus and tracking for all the laser beams.

Section 3: Advantages and Disadvantages of the Two Approaches

Advantages of Using an Array of High-Quality Lenslets:
- Better control of laser beams
- Improved maintaining focus and tracking
- Lower cost compared to using a single high-numerical-aperture lens

Disadvantages of Using an Array of High-Quality Lenslets:
- More complex design and manufacturing process
- Increased chance of alignment errors
- Potential for increased chromatic aberration

Advantages of Using a Single, High-Numerical-Aperture Annular-Field-of-View Conventional Lens:
- Simpler design and manufacturing process
- Reduced chance of alignment errors
- Lower chromatic aberration

Disadvantages of Using a Single, High-Numerical-Aperture Annular-Field-of-View Conventional Lens:
- Larger depth of focus, which may make maintaining focus and tracking more difficult
- Higher cost compared to using an array of high-quality lenslets

Conclusion:
In this lesson, we learned about the challenges of achieving high data rates in optical data storage systems and the different techniques used to address these challenges. We also explored the advantages and disadvantages of using an array of high-quality lenslets versus a single, high-numerical-aperture annular-field-of-view conventional lens for designing an objective lens for optical data storage systems. By understanding these techniques, we can apply them to other areas of science and technology to improve data storage and retrieval systems.

Lesson: Introduction to Photography

## Section 1: Theoretical Concepts

Photography is the art and science of creating images using light and other electromagnetic radiation, either electronically or chemically on light-sensitive materials. It is a method of recording and capturing moments, memories, and experiences visually. In this lesson, we will explore the basic principles of photography, including exposure, composition, and lighting.

Exposure refers to the amount of light that reaches the camera's sensor or film. The three elements that control exposure are shutter speed, aperture, and ISO. Shutter speed determines how long the camera's shutter is open, allowing light to enter the camera. Aperture refers to the size of the opening in the lens that allows light to pass through. ISO is a measure of how sensitive the camera's sensor or film is to light.

Composition is the arrangement of visual elements in a photograph. It involves the placement of subjects, colors, and shapes within the frame to create a balanced and visually appealing image. Good composition includes the rule of thirds, leading lines, and symmetry.

Lighting is the use of light to enhance or alter the appearance of an object or scene. It can be natural or artificial and can create different moods and emotions in a photograph. Good lighting can make a subject look more attractive, interesting, or dramatic.

## Section 2: Practical Examples

Now that we understand the basic principles of photography, let's apply them to some real-world scenarios.

Scenario 1: You are taking a photo of a friend in a park during a sunny day. To ensure proper exposure, set your camera's ISO to 100, aperture to f/8, and shutter speed to 1/500th of a second. This will allow enough light to enter the camera while avoiding overexposure. Use the rule of thirds to compose the image, placing your friend off-center and aligning them with natural elements in the background. Use the sun as your key light, positioning it behind you to create a silhouette effect.

Scenario 2: You are taking a portrait of a professional model in a studio. Set your camera's ISO to 100, aperture to f/2.8, and shutter speed to 1/200th of a second. Use a softbox as your main light source, positioning it above and slightly to the side of the model. Use a reflector or secondary light source to fill in shadows and create catchlights in the model's eyes. Use the rule of thirds to compose the image, placing the model's eyes or hands on the intersection points.

## Section 3: Self-Debating Discussions

What are some ways to improve your photography skills? How do different types of lighting affect the mood of a photograph? What are some common mistakes beginners make when composing an image?

## Glossary
- Exposure: The amount of light that reaches the camera's sensor or film.
- Composition: The arrangement of visual elements in a photograph.
- Lighting: The use of light to enhance or alter the appearance of an object or scene.

## Conclusion

In this lesson, we explored the basic principles of photography, including exposure, composition, and lighting. We then applied these principles to real-world scenarios and engaged in self-debating discussions to further our understanding. By mastering these concepts, we can improve our photography skills and capture stunning images that tell a story.

Lesson: Investing in Stocks

### Introduction
Investing in stocks is a great way to grow your money over time. In this lesson, we will learn about different types of stocks and how to invest in them. We will also explore the benefits and risks associated with investing in stocks.

### Section 1: What are Stocks?
Stocks represent ownership in a company. When you buy a stock, you are essentially buying a small piece of the company. This means that you become a part-owner of the company and are entitled to a share of its profits. Companies issue stocks to raise money to fund their operations. In return, they offer a portion of their future earnings to investors in the form of dividends.

There are two main types of stocks: common and preferred. Common stocks give shareholders voting rights and the potential for dividends. Preferred stocks do not have voting rights, but they usually pay out a fixed dividend.

### Section 2: How to Invest in Stocks
To invest in stocks, you will need to open a brokerage account. A brokerage account is a type of account that allows you to buy and sell stocks. There are many different brokerage firms to choose from, so it's important to research and compare them before opening an account.

Once you have opened a brokerage account, you can start investing in stocks. Here are some steps to follow:

1. Research the company: Before investing in a company, you should research it to understand its business model, financial health, and competitive position. You can find this information in the company's annual report, 10-K filing, and other financial statements.

2. Determine your investment goals: Your investment goals will help guide your decision-making process. Are you looking for long-term growth or income? Do you want to invest in stable, well-established companies or take on more risk for potentially higher returns?

3. Choose your investments: Based on your research and investment goals, you can now choose which stocks to invest in. Some investors prefer to buy individual stocks, while others choose to invest in mutual funds or exchange-traded funds (ETFs) that hold a diversified portfolio of stocks.

4. Monitor your investments: It's important to monitor your investments regularly to ensure that they are performing as expected. Keep an eye on the company's financial performance, news, and industry trends.

### Section 3: Benefits and Risks of Investing in Stocks
There are several benefits to investing in stocks, including:

1. Potential for high returns: Over long periods of time, stocks have historically provided higher returns than other investments like bonds or savings accounts.

2. Diversification: Investing in stocks allows you to diversify your investment portfolio, reducing your overall risk.

3. Ownership: When you invest in stocks, you become a part-owner of the company and may be entitled to a share of its profits through dividends.

However, there are also risks associated with investing in stocks, including:

1. Market risk: Stock prices can fluctuate due to factors such as economic conditions, changes in interest rates, and investor sentiment.

2. Company risk: Even successful companies can experience setbacks, such as poor management decisions, legal issues, or changes in the market.

3. Liquidity risk: If you need to sell your stocks quickly, you may not be able to get the full value of your investment.

### Glossary
- Brokerage account: An account that allows you to buy and sell stocks.
- Dividends: A payment made by a company to its shareholders.
- Mutual funds: Investment vehicles that pool money from many investors to purchase a diversified portfolio of stocks, bonds, or other assets.
- Exchange-traded funds (ETFs): Similar to mutual funds, ETFs hold a basket of securities and trade like individual stocks on an exchange.

### Conclusion
Investing in stocks can be a great way to grow your wealth over time.

Lesson: How to Count Objects

Introduction:
Counting objects is an essential skill in mathematics. In this lesson, we will learn how to count objects using different methods, such as visual counting, counting by groups, and using mathematical equations.

Section 1: Visual Counting
Objective: To understand the concept of visual counting and practice counting objects.

Theory: Visual counting is a method of counting objects by looking at them. We can use our eyes to count the number of objects in a group. For example, if we have ten apples in a basket, we can count them one by one to find out how many there are.

Practice: Let's try some examples of visual counting:

1. How many stars are there in the flag of the United States? (Answer: 50)
2. How many legs does a spider have? (Answer: 8)
3. How many sides does a triangle have? (Answer: 3)

Discussion: Why is visual counting important? How does it help us in our daily lives?

Section 2: Counting by Groups
Objective: To understand the concept of counting by groups and practice counting objects.

Theory: Counting by groups is a method of counting objects by dividing them into smaller groups. For example, if we have twenty pencils and we want to count them, we can divide them into groups of five and count each group separately.

Practice: Let's try some examples of counting by groups:

1. If we have 24 apples and we want to count them, how can we do it? (Answer: We can divide them into groups of 4 and count each group separately.)
2. If we have 72 candies and we want to count them, how can we do it? (Answer: We can divide them into groups of 9 and count each group separately.)

Discussion: Why is counting by groups important? How does it help us in our daily lives?

Section 3: Using Mathematical Equations
Objective: To understand the concept of using mathematical equations to count objects.

Theory: We can use mathematical equations to count objects. For example, if we have x number of objects and we want to know how many more objects we need to reach a total of 100, we can use the equation: x + y = 100, where y represents the number of additional objects we need.

Practice: Let's try some examples of using mathematical equations to count objects:

1. If we have 56 objects and we want to know how many more objects we need to reach a total of 100, what is the value of y? (Answer: We can use the equation x + y = 100, where x = 56. Solving for y, we get y = 100 - 56 = 44.)
2. If we have 38 objects and we want to know how many more objects we need to reach a total of 70, what is the value of y? (Answer: We can use the equation x + y = 70, where x = 38. Solving for y, we get y = 70 - 38 = 32.)

Discussion: Why is using mathematical equations important? How does it help us in our daily lives?

Conclusion: Counting objects is an essential skill in mathematics that helps us in our daily lives. By using different methods such as visual counting, counting by groups, and using mathematical equations, we can easily count objects and solve problems related to counting.

Lesson: Introduction to Traditional Chinese Medicine (TCM)

#### Section 1: Introduction to Traditional Chinese Medicine (TCM)

Traditional Chinese Medicine (TCM) is a system of medicine that has been practiced in China for over 2,000 years. It is based on the concept of Qi (pronounced "chee"), which is the vital energy that flows through the body along meridians or channels. TCM aims to restore the balance of Qi in the body by using various therapies such as acupuncture, herbal medicine, massage, and dietary changes.

In this lesson, we will learn about the basic principles of TCM, including the concept of Qi, the five elements, and the meridians. We will also explore how TCM is used to diagnose and treat various health conditions.

#### Section 2: The Concept of Qi

Qi is the central concept in TCM. It is the vital energy that flows through the body along meridians or channels. There are twelve main meridians, each corresponding to a specific organ. When the Qi is balanced and flowing freely, the body is healthy. However, when there is an imbalance or blockage in the Qi, illness can result.

The following questions and answers will help you understand the concept of Qi:

**Question:** What is Qi?
**Answer:** Qi is the vital energy that flows through the body along meridians or channels.

**Question:** What happens when the Qi is imbalanced or blocked?
**Answer:** When the Qi is imbalanced or blocked, illness can result.

**Question:** How does TCM aim to restore the balance of Qi in the body?
**Answer:** TCM aims to restore the balance of Qi in the body by using various therapies such as acupuncture, herbal medicine, massage, and dietary changes.

#### Section 3: The Five Elements

The five elements in TCM are wood, fire, earth, metal, and water. These elements represent different aspects of the natural world and are believed to be present in all things. When the elements are in balance, the body is healthy. However, when one element becomes too dominant, it can lead to illness.

The following questions and answers will help you understand the five elements in TCM:

**Question:** What are the five elements in TCM?
**Answer:** The five elements in TCM are wood, fire, earth, metal, and water.

**Question:** How do the five elements relate to health?

#### Section 4: Diagnosing and Treating Illness with TCM

In TCM, illness is believed to result from an imbalance or blockage in the Qi. A practitioner will diagnose the patient by taking their pulse, looking at their tongue, and asking them questions about their symptoms. Once the diagnosis is made, the practitioner will prescribe a treatment plan that may include acupuncture, herbal medicine, massage, or dietary changes.

The following questions and answers will help you understand how TCM is used to diagnose and treat illness:

**Question:** How does a TCM practitioner diagnose illness?
**Answer:** A TCM practitioner diagnoses illness by taking the patient's pulse, looking at their tongue, and asking them questions about their symptoms.

**Question:** What types of treatments does a TCM practitioner use?

Lesson: How to Analyze Customer Sentiment on Social Media

Introduction:
In today's digital age, social media has become an essential tool for businesses to connect with their customers. However, it also presents a challenge for companies to monitor and analyze customer sentiment. In this lesson, we will learn how to analyze customer sentiment on social media using data analysis techniques.

Section 1: Understanding Customer Sentiment
- Customer sentiment refers to the emotional tone or attitude expressed by customers towards a company or its products/services.
- It can be positive, negative, or neutral.
- Analyzing customer sentiment helps businesses understand how their customers feel about their brand, products, and services.

Section 2: Collecting Data
- To analyze customer sentiment, we need to collect data from social media platforms where customers interact with the company.
- This data can be collected using social media monitoring tools that track mentions of the company, its products/services, and related keywords.
- The data collected should include the text of the posts, the user's profile information, and the number of likes/retweets/shares.

Section 3: Analyzing Data
- Once the data is collected, we need to analyze it to determine the sentiment expressed by customers.
- This can be done manually by reading each post and categorizing it as positive, negative, or neutral.
- Alternatively, businesses can use data analysis tools that use natural language processing (NLP) algorithms to automatically classify posts based on their sentiment.
- These tools can also provide additional insights, such as the most common issues customers are complaining about and the overall sentiment trend over time.

Section 4: Interpreting Results
- After analyzing the data, we can interpret the results to understand how customers feel about the company and its products/services.
- For example, if the majority of posts are positive, it indicates that customers are generally satisfied with the company's offerings.
- On the other hand, if the majority of posts are negative, it suggests that there may be issues that need to be addressed.
- Businesses can use this information to identify areas for improvement and take steps to address customer concerns.

Section 5: Applying Skills Gained
- The skills gained from analyzing customer sentiment on social media can be applied to various scenarios.
- For example, businesses can use these skills to monitor and analyze customer sentiment for competitors, industry trends, or political issues.
- Additionally, these skills can be used to conduct market research and gather feedback on new product ideas.

Conclusion:
Analyzing customer sentiment on social media is an essential tool for businesses to understand how their customers feel about their brand, products, and services. By following the steps outlined in this lesson, businesses can collect and analyze data to gain valuable insights into customer sentiment.

Lesson Title: Understanding Hang Tags in the Clothing Industry

Introduction:
Hang tags are an essential part of the clothing industry. They provide information about the product, such as size, material, and brand name. In this lesson, we will learn about hang tags, their importance in the clothing industry, and how they can help us make informed purchasing decisions.

Section 1: What are Hang Tags?
Hang tags are small pieces of paper or fabric that are attached to clothing items. They contain important information about the product, such as the brand name, size, material, and care instructions. Hang tags are usually attached to the clothing item using a string or a loop.

Section 2: Why are Hang Tags Important?
Hang tags are important because they provide consumers with valuable information about the product. This information helps consumers make informed purchasing decisions. For example, if a consumer is looking for a cotton shirt, they can look for a hang tag that indicates the shirt is made of cotton. Additionally, hang tags help prevent confusion and miscommunication between the manufacturer and the consumer.

Section 3: Types of Hang Tags
There are several types of hang tags, including:

1. Barcode Hang Tags: These tags contain a barcode that can be scanned by a machine. The barcode contains information about the product, such as the price and quantity.

2. Custom Hang Tags: These tags are designed specifically for a particular product or brand. They may contain unique designs, logos, or slogans.

3. Recycled Hang Tags: These tags are made from recycled materials, such as paper or plastic. They are environmentally friendly and help reduce waste.

Section 4: How to Read Hang Tags
To read a hang tag, you need to know what information to look for. Here are some common pieces of information found on hang tags:

1. Brand Name: This is the name of the company that manufactured the product.

2. Size: This is the size of the clothing item, such as "small" or "medium."

3. Material: This is the type of material used to make the clothing item, such as "cotton" or "polyester."

4. Care Instructions: These are the instructions for washing, drying, and storing the clothing item.

Section 5: Practical Examples
Let's say you are shopping for a new pair of jeans. You find a pair that you like, but you are not sure what size to buy. By looking at the hang tag, you can see that the size medium fits true to size. This information helps you make an informed decision about which size to purchase.

Conclusion:
In conclusion, hang tags are an important part of the clothing industry. They provide valuable information about the product, such as the brand name, size, material, and care instructions. By understanding the importance of hang tags and how to read them, we can make informed purchasing decisions and choose products that meet our needs and preferences.


text: The distance between these two cities is around 770Kms, and can be reached in approximately 12hrs 50min.VRL Travels operates close to 2 buses from Haleangadi to Pune. You have buses starting from 05:40 PM, till 06:40 PM. Minimum fare for bus travel along this route is Rs.800, and the maximum fare is close to Rs.1050..

Lesson: How to Calculate Distance and Time Between Two Cities Using Public Transportation

## Section 1: Introduction

In this lesson, we will learn how to calculate the distance and time between two cities using public transportation. We will use the example of Haleangadi and Pune to demonstrate the process.

## Section 2: Calculating Distance and Time

To calculate the distance between two cities, we need to know their coordinates. The coordinates of Haleangadi are 13.7396° N and 74.7684° E, while the coordinates of Pune are 18.5194° N and 73.8556° E.

Using these coordinates, we can calculate the distance between the two cities using the Haversine formula:

distance = 2 * 3.14159 * (lat2 - lat1) * (cos(lat1) * sin(lon2) - cos(lat2) * sin(lon1) * cot(lat1))

where:
- distance is the distance between the two cities in kilometers
- lat1 and lat2 are the latitudes of Haleangadi and Pune, respectively
- lon1 and lon2 are the longitudes of Haleangadi and Pune, respectively
- cot(lat1) is the cosine of the latitude of Haleangadi

Using this formula, we can calculate the distance between Haleangadi and Pune to be approximately 770 km.

Next, we need to calculate the time it takes to travel between the two cities. To do this, we need to know the speed of the transportation being used. Let's assume that the bus traveling between Haleangadi and Pune has an average speed of 50 km/h.

Using this speed, we can calculate the time it takes to travel between the two cities as follows:

time = distance / speed

where:
- time is the time it takes to travel between the two cities in hours
- distance is the distance between the two cities in kilometers
- speed is the speed of the transportation being used

Using this formula, we can calculate the time it takes to travel between Haleangadi and Pune to be approximately 12.5 hours.

## Section 3: Practical Examples

Let's apply the concepts we learned in the previous section to a real-world scenario. Suppose you want to travel from Haleangadi to Pune by bus. You can use the VRL Travels website or app to book a ticket. The website or app will display the available buses and their schedules.

You can choose a bus that departs at 05:40 PM and arrives in Pune at 06:40 PM. The minimum fare for this bus is Rs.800, and the maximum fare is close to Rs.1050.

Once you have booked your ticket, you can use the information we learned in the previous section to estimate the time of arrival in Pune. Since the bus has an average speed of 50 km/h, it will take approximately 12.5 hours to travel between Haleangadi and Pune. This means that you will arrive in Pune at approximately 6:40 PM.

## Glossary

- Haversine formula: a formula used to calculate the great-circle distance between two points on a sphere, given their longitudes and latitudes
- cosine: the ratio of the adjacent side to the hypotenuse of a right triangle
- cotangent: the ratio of the hypotenuse to the adjacent side of a right triangle
- kilometers per hour: a unit of speed used to measure the speed of transportation

## Conclusion

In this lesson, we learned how to calculate the distance and time between two cities using public transportation. We applied this knowledge to a real-world scenario of traveling from Haleangadi to Pune by bus. By understanding the concepts and formulas involved, we can make informed decisions about our travel plans and estimate the time of arrival at our destination.

Risk of insulin-dependent diabetes mellitus in patients undergoing carotid endarterectomy.
There is conflicting evidence regarding the association of diabetes mellitus (DM) and insulin use with outcomes after carotid endarterectomy (CEA). Therefore, we sought to evaluate the risk of insulin-dependent DM (IDDM) and noninsulin-dependent DM (NIDDM) on 30-day outcomes after CEA. We identified patients undergoing CEA from the Targeted Vascular module of the National Surgical Quality Improvement Program (2011-2015) and stratified patients on the basis of their preprocedural symptom status. We compared 30-day outcomes between nondiabetics and patients with NIDDM or IDDM, with 30-day stroke/death as the primary end point. Of 16,739 CEA patients, 9784 (58%) were asymptomatic, of whom 6720 (69%) had no diagnosis of DM, 1109 (11%) had IDDM, and 1955 (20%) had NIDDM. Of the 6955 symptomatic patients, 4982 (72%) had no diagnosis of DM, 810 (12%) had IDDM, and 1163 (17%) had NIDDM. Among asymptomatic patients, patients with IDDM experienced higher rates of 30-day stroke/death compared with those without DM (3.4% vs 1.5%; P < .001), whereas those with NIDDM experienced rates similar to those of patients without DM (2.1% vs 1.5%; P = .1). Moreover, asymptomatic patients with IDDM and an anatomic high-risk criterion experienced a 30-day stroke/death rate of 6.6%. After adjustment, IDDM was associated with 30-day stroke/death in asymptomatic patients compared with patients without DM (odds ratio, 2.3; 95% confidence interval, 1.5-3.4; P < .001), but NIDDM was not (odds ratio, 1.4; 95% confidence interval, 1.0-2.1; P = .1). In comparison, among symptomatic patients, those with IDDM and NIDDM experienced similar rates of 30-day stroke/death as patients without DM (4.9% vs 3.6% and 4.0% vs 3.6%; both P > .1). After adjustment, neither IDDM nor NIDDM was associated with 30-day stroke/death in symptomatic patients compared with symptomatic patients without DM. Rates of 30-day stroke/death after CEA in asymptomatic patients with IDDM exceed international vascular societies' guideline thresholds for acceptable outcomes in asymptomatic patients, especially those with anatomic high-risk criteria. Thus, asymptomatic patients with IDDM may not benefit from CEA, although more data are needed about the natural history of carotid disease in this population.

New therapies for optic neuropathies: development in experimental models.
Experimental models of human diseases have affected the design and direction of both basic and clinical research into understanding the pathogenesis and treatments of demyelinating disease, stroke, and hereditary disorders of the central nervous system. However, in spite of major advances in molecular research that have linked Leber Hereditary Optic Neuropathy to mutations in mitochondrial DNA, there has been relatively little focus in applying basic scientific methodologies to optic neuropathies other than glaucoma. The relative absence of detailed scientific knowledge about the basic mechanisms involved in the pathogenesis of optic nerve injury has contributed to the use of empiric therapies for neuro-ophthalmic optic neuropathies. Over the past decade major clinical trials, such as the Optic Neuritis Treatment Trial and Ischemic Optic Neuropathy Decompression Trial, have proven that currently available treatment options for demyelinating and ischemic optic neuropathies are ineffective and can even be harmful. Although the pathogenesis of visual failure in demyelinating, ischemic, and hereditary optic neuropathies appears diverse, a final common pathway for irreparable optic nerve injury may exist. This article reviews several models of experimental optic neuropathies that may aid in the development of novel treatments for neuro-ophthalmic disorders of the optic nerve during the 21st century.
