Q:

Improving telerik Radgridview Scroller Performance

Hello I was trying to Improve the dragging of scroll of the datagrid. It's very slow, Mouse scroll is decent. I was wondering if anyone knows how I can speed this up. I have
EnableColumnVirtualization="False"
EnableRowVirtualization="True"
Any tips on how abouts i should speed it up?

A:

It's only slow while debugging in VS. If you change your build configuration in Build>Configuration Manager to Release and run the application compiled for release outside of VS it will fly...
Also, in most cases it is best if you don't manually change virtualization settings... allow RadGridView to control virtualization settings on its own and 99.9% of the time that will give you the best performance.

Lesson:

**Lesson Title: Improving Telerik RadGridView Scroller Performance**

**Lesson Overview:** In this lesson, we will learn how to improve the scrolling performance of a Telerik RadGridView. We will cover the basics of virtualization, debugging, and building for release.

**Lesson Outline:**

1. Introduction to Virtualization
2. Debugging and Building for Release
3. Conclusion

**1. Introduction to Virtualization:**

Virtualization is a technique used by Telerik RadGridView to improve its scrolling performance. It allows the GridView to display only the necessary rows and columns based on the current viewport. This reduces the amount of data that needs to be rendered, which in turn speeds up the scrolling performance.

**2. Debugging and Building for Release:**

When developing an application, we often use the debug build configuration. However, this build configuration is not optimized for performance. Instead, we should use the release build configuration when testing our application outside of Visual Studio.

To switch to the release build configuration, go to **Build > Configuration Manager**. Select the **Active Solution Platform** dropdown and choose the desired platform (x86 or x64). Then, select **Release** under the **Configuration** dropdown.

Once you have switched to the release build configuration, your application will be optimized for performance. This will result in faster scrolling for your RadGridView.

**3. Conclusion:**

In this lesson, we learned about virtualization and how it can improve the scrolling performance of a Telerik RadGridView. We also learned about the importance of building for release instead of debug when testing outside of Visual Studio. By following these tips, you can ensure that your RadGridView performs at its best.

**Glossary:**

- Virtualization: A technique used by Telerik RadGridView to improve scrolling performance by displaying only the necessary rows and columns based on the current viewport.
- Debugging: The process of finding and fixing errors in your code.
- Building for Release: Compiling your application in a way that optimizes it for performance, typically by removing debug information and other unnecessary files.

**Conclusion:**

By following the tips outlined in this lesson, you can improve the scrolling performance of your Telerik RadGridView. Remember to enable virtualization and build for release when testing outside of Visual Studio. With these techniques, you can ensure that your RadGridView performs at its best.

**Lesson: Introduction to Spectrophotometry**

**Objective:** To introduce students to the concept of spectrophotometry, its applications, and how it works.

**Introduction:** Spectrophotometry is a technique used to measure the concentration of a substance in a solution by analyzing the amount of light it absorbs at different wavelengths. This method is widely used in chemistry, biology, and other fields to study the properties of matter.

**Main Topics:**

1. What is spectrophotometry?
2. How does spectrophotometry work?
3. Applications of spectrophotometry
4. Mathematical aspects of spectrophotometry

**Section 1: What is spectrophotometry?**

Spectrophotometry is a branch of analytical chemistry that deals with the measurement of the intensity of light transmitted, reflected, or absorbed by a substance at different wavelengths. It is based on the Beer-Lambert Law, which states that the absorbance of a solution is directly proportional to its concentration and path length.

**Section 2: How does spectrophotometry work?**

Spectrophotometry works by shining a light source (usually a lamp) through a sample solution. The light passes through a monochromator, which selects a specific wavelength of light to pass through the sample. The light then hits the sample and some of it is absorbed by the substance in the solution. The remaining light is measured by a detector, which generates a spectrum showing the absorbance of the substance at different wavelengths.

**Section 3: Applications of spectrophotometry**

Spectrophotometry has many applications in various fields, including:

- Chemistry: Identifying unknown compounds, determining the concentration of solutions, and studying reaction kinetics.
- Biology: Analyzing proteins, nucleic acids, and other biomolecules, and measuring enzyme activity.
- Environmental science: Monitoring water quality, air pollution, and soil contamination.
- Forensics: Identifying unknown substances and determining the composition of drugs.

**Section 4: Mathematical aspects of spectrophotometry**

The Beer-Lambert Law states that the absorbance (A) of a solution is directly proportional to its concentration (c) and path length (l), according to the equation:

A = εcl

where ε is the molar absorptivity of the substance, which is a constant for a given substance at a specific wavelength.

**Conclusion:**

Spectrophotometry is a powerful tool used in various fields to study the properties of matter. By understanding the principles behind this technique, we can apply it to solve real-world problems and gain valuable insights into the world around us.

The everyday items used by a pair of British brothers to detain a stabbing suspect in Sydney have been immortalised in a Twitter meme.

Luke and Paul O'Shaughnessy, from Bury in Greater Manchester, said they acted on instinct as they saw a man wielding a large blade running through the streets of the Australian city centre on Tuesday.

Racing down from their fourth-floor office, the brothers chased the attacker before tackling him to the ground and helping pin him down with a chair and milk crate.

Now the hashtag #milkcrate has gone viral and praised the actions of the brothers while mocking US attitudes to gun laws at the same time.

After actor Russell Crowe tweeted “Make Australia crate again”, the rest of Twitter picked up on his pun of Donald Trump’s election-winning slogan - and highlighted how the O’Shaughnessy brothers did not need guns to stop an attacker:

Let’s make Australia crate again — Russell Crowe (@russellcrowe) August 13, 2019

America - Walmart - gunman.

Multiple other people carrying guns - didn’t stop the gunman.

Sydney - guy with a knife - taken down by a crowd with a chair and a milk crate.

Sydney: *one casualty after Police arrive in 40 minutes*

Americans: sEe BaNnInG gUnS wOnT dO aNyThInG#milkcrate — Liz Saunders (@saunders_liz) August 13, 2019

Dear America. I have a #MilkCrate. It protects my family, and yet, I don't even have to keep in a safe, get it licensed, or worry that one of my children might accidentally use it to shoot someone. — Lateralist (@Lateralist76) August 13, 2019

Both brothers said they were "proud" of their actions, but denied they were heroes - despite police and the country's prime minister commending them for helping to tackle the suspect.

Paul, 37, a former midfielder with crisis-club Bury between 1999 and 2004, said: "I didn't even think about it.

"I just thought is my brother going to be OK as we ran towards him.”

He added: "Our values as brothers is we are protectors.”

View photos The suspect in the attack was named as 21-year-old Mert Ney (Andrew Denney/7 News/PA) More

New South Wales Police Superintendent Gavin Wood, speaking to reporters near the scene, praised the men who tackled the suspect, also said to have included Manchester man Lee Cuthbert.

Mr Wood said: "They are significantly brave people. They approach the person... with clear evidence of a stabbing previously. These people are heroes, and I want to acknowledge that.

Philip Lee Miller, M.D., Author, The Life Extension Revolution; Founder and Director, California Age Management Institute. The perils of modern medicine are now widely appreciated. Miller says all solutions offered to mitigate "the health-care crisis" in America are economic – a zero-sum game. We are now at a critical juncture in the evolution of medicine, and Miller states that “transformation" is the needed approach to solving the problems that plague our medical system. Economic solutions lead to cost-shifting, which he says will not improve the underlying malady: the declining loss of quality of care. A newer model is evolving: antiaging/functional/longevity medicine. Miller asserts that national debate should be posed in terms of goals and aspirations for a new system, not simply universal methods of payment..

Andrew Scheer estime qu’un corridor énergétique reliant l’Ouest et l’Est canadien profiterait autant aux Québécois qu’au reste du Canada. Si l’Alberta réclamait un nouveau pipeline, le Québec pourrait-il bénéficier de ce nouveau corridor pour vendre son électricité?

Le corridor énergétique du chef conservateur permettrait de transporter le pétrole de l’Ouest vers de nouveaux marchés.

Ce sera un corridor transnational qui va générer des avantages économiques et sociaux pour tout le pays. Andrew Scheer, chef du Parti conservateur

Mais Hydro-Québec pourrait-elle tirer avantage de ce corridor pour vendre de l’électricité à l’Ontario et aux provinces de l’Ouest? Les faits nous poussent à croire que non.

Du côté de l’Ontario...

Hydro-Québec peut doubler ses exportations d’électricité vers l’Ontario sans construire une seule nouvelle ligne de transport. Mais le premier ministre Doug Ford refuse d’importer plus d’électricité du Québec.

Entre autres, parce que l’Ontario Power Generation – une société qui appartient au gouvernement ontarien – investit 26 milliards de dollars dans la restauration de ses réacteurs nucléaires, une industrie qui emploie 18 000 Ontariens.

De plus, la société ontarienne a investi près de 3 milliards de dollars dans des centrales au gaz pour accroître ses revenus.

Parions que le gouvernement ontarien cherchera à rentabiliser ses investissements avant d’acheter plus d’électricité québécoise.

... et de celui du Manitoba

Le Manitoba, lui, nage déjà dans les surplus d’électricité.

Plus loin vers l’ouest, le transport de l’électricité du Québec coûterait des milliards de dollars. À titre d’exemple, la construction de l’interconnexion Appalaches-Maine d’Hydro-Québec est évaluée à 2,5 millions de dollars du kilomètre. D’est en ouest, l’Ontario fait plus de 1500 km!

Finalement, la proximité d’une ligne à haute tension accroîtrait les risques de corrosion et de détérioration d’un pipeline. Il serait possible d’éviter le problème, mais le prix de construction serait plus élevé et cela augmenterait les coûts du transport du pétrole albertain.

Lesson: Corridor Énergétique

Introduction:

L'énergie est un élément essentiel de notre vie quotidienne. Elle est utilisée pour chauffer nos maisons, cuisiner nos repas et faire fonctionner nos appareils électroniques. Cependant, la manière dont nous obtenons et utilisons l'énergie a un impact sur notre environnement et notre société. Dans ce chapitre, nous explorerons comment le corridor énergétique peut aider à réduire notre impact sur l'environnement tout en fournissant des avantages économiques et sociaux.

Section 1: Définition et importance du corridor énergétique

Un corridor énergétique est une route ou une ligne de transport qui permet de transporter de l'énergie d'une région à une autre. Il peut être utilisé pour transporter de l'électricité, du gaz naturel, du pétrole ou d'autres formes d'énergie. L'importance du corridor énergétique tient au fait qu'il peut aider à réduire les coûts de transport et à fournir des avantages économiques et sociaux pour tout le pays. En effet, il peut permettre à des régions riches en énergie de vendre leur énergie à des marchés plus éloignés, tout en réduisant leur dépendance aux combustibles fossiles.

Section 2: Avantages du corridor énergétique

Les avantages du corridor énergétique sont multiples. Premièrement, il peut permettre à des régions riches en énergie de vendre leur énergie à des marchés plus éloignés, tout en réduisant leur dépendance aux combustibles fossiles. Deuxièmement, il peut permettre à des entreprises d'utiliser des sources d'énergie plus proches de leur lieu de production, ce qui peut réduire leurs coûts de transport et leur impact environnemental. Troisièmement, le corridor énergétique peut stimuler l'économie locale en créant des emplois dans les secteurs de l'énergie et de la construction.

Section 3: Comment Hydro-Québec peut-elle tirer avantage du corridor énergétique?

Malgré les avantages du corridor énergétique, il y a des limitations à son utilisation. Par exemple, Hydro-Québec peut doubler ses exportations d'électricité vers l'Ontario sans construire une seule nouvelle ligne de transport. Cependant, cela ne signifie pas que Hydro-Québec ne pourra jamais tirer avantage du corridor énergétique. En effet, si le gouvernement de l'Ontario ou d'autres provinces de l'Ouest décident d'augmenter leur demande d'électricité verte, Hydro-Québec pourrait certainement jouer un rôle important dans la fourniture de cette énergie.

Conclusion:

En résumé, le corridor énergétique offre de nombreux avantages pour notre pays, allant des réductions de coûts de transport aux bénéfices pour l'environnement. Bien que Hydro-Québec ne puisse pas immédiatement tirer avantage du corridor énergétique, elle pourrait certainement jouer un rôle important dans le futur si les demandes d'électricité verte augmentent. En tant qu'étudiant, il est important de comprendre les différents aspects du corridor énergétique et de discuter avec ses pairs et son enseignant sur les possibilités et les limites de ce concept.

The effects of aging on the frequency of nerve fibers in rhesus monkey striate cortex.
In the rhesus monkey primary visual cortex, there are bundles of vertically oriented myelinated axons, which mainly contain efferent fibers originating from pyramidal cells. At the level of layer 4Cbeta, the bundles are regularly arranged and the nerve fibers in them are closely packed. In order to determine if a significant loss of intracortical nerve fibers occurs as the primate cerebral cortex ages, the frequency of vertically oriented myelinated fibers was examined at the level of layer 4Cbeta in 1 microm-thick, tangential sections. The results show no statistically significant differences in the numbers of vertically oriented fibers beneath 1 mm(2) of cortical surface between young, middle-aged, and old monkeys, and electron microscopic examination reveals few signs of degenerating axons. There is, however, an age-related breakdown of the myelin in sheaths that surround some axons. Thus, the data indicate that there is not a loss of vertically oriented myelinated fibers from the cortical gray matter during aging, although their sheaths may be altered.

Lesson Title: The Effects of Aging on the Frequency of Nerve Fibers in Rhesus Monkey Striate Cortex

Introduction:
In this lesson, we will learn about the effects of aging on the frequency of nerve fibers in the rhesus monkey striate cortex. We will cover the following topics:

1. Anatomy of the rhesus monkey striate cortex
2. Examination of the frequency of vertically oriented myelinated fibers
3. Age-related breakdown of myelin sheaths
4. Conclusion and application of skills gained from this topic

Section 1: Anatomy of the Rhesus Monkey Striate Cortex
The rhesus monkey striate cortex is a part of the brain responsible for processing visual information. It contains bundles of vertically oriented myelinated axons, which mainly contain efferent fibers originating from pyramidal cells. These fibers are arranged in a regular pattern and are closely packed together.

Section 2: Examination of the Frequency of Vertically Oriented Myelinated Fibers
To determine if there is a significant loss of intracortical nerve fibers as the primate cerebral cortex ages, researchers examined the frequency of vertically oriented myelinated fibers in 1 microm-thick, tangential sections of the striate cortex. They found no statistically significant differences in the numbers of vertically oriented fibers beneath 1 mm² of cortical surface between young, middle-aged, and old monkeys.

Section 3: Age-Related Breakdown of Myelin Sheaths
However, electron microscopic examination revealed few signs of degenerating axons. Instead, there was an age-related breakdown of the myelin in sheaths that surround some axons. This breakdown is thought to be caused by oxidative stress and other factors that occur during aging.

Section 4: Conclusion and Application of Skills Gained from this Topic
In conclusion, the study shows that there is no significant loss of intracortical nerve fibers as the primate cerebral cortex ages. However, there is an age-related breakdown of myelin sheaths that surround some axons. This information can be applied to further studies on the effects of aging on the nervous system and could potentially lead to interventions that slow down or prevent age-related neurodegenerative diseases.

Glossary:
- Rhesus monkey: A species of monkey used in scientific research.
- Striate cortex: A part of the brain responsible for processing visual information.
- Myelinated axons: Axons that have a protective coating called myelin sheath.
- Efferent fibers: Fibers that transmit signals from the brain to other parts of the body.
- Pyramidal cells: Neurons that have a pyramid-shaped body and are involved in processing information.

- Tangential sections: Thin slices of tissue that are cut perpendicular to the surface of an organ.
- Electron microscopy: A technique used to examine the structure of cells and tissues using a beam of electrons instead of light.

Conclusion:
In this lesson, we learned about the effects of aging on the frequency of nerve fibers in the rhesus monkey striate cortex. We covered topics such as the anatomy of the striate cortex, the examination of the frequency of vertically oriented myelinated fibers, and the age-related breakdown of myelin sheaths. This information can be applied to further studies on the effects of aging on the nervous system and could potentially lead to interventions that slow down or prevent age-related neurodegenerative diseases.

Microelectronic imagers are used in digital cameras, wireless devices with picture capabilities, and many other applications. Cell phones and Personal Digital Assistants (PDAs), for example, incorporate microelectronic imagers for capturing and sending digital images. The use of microelectronic imagers in electronic devices is steadily increasing as imagers become smaller and produce higher quality images with increased pixel counts.
Microelectronic imagers include image sensors that use Charged Coupled Device (CCD) systems, Complementary Metal-Oxide Semiconductor (CMOS) systems, or other systems. CCD image sensors have been widely used in digital cameras and other applications. CMOS image sensors are also becoming very popular because they have low production costs, high yields, and small sizes. CMOS image sensors provide these advantages because they are manufactured using technology and equipment developed for fabricating semiconductor devices. CMOS image sensors, as well as CCD image sensors, are accordingly “packaged” to protect their delicate components and provide external electrical contacts.
FIG. 1 is a schematic side cross-sectional view of a conventional packaged microelectronic imager 1. The imager 1 includes a die 10, an interposer substrate 20 attached to the die 10, a housing 30 attached to the interposer substrate 20, and an optics unit 50 attached to the housing 30. The housing 30 has an opening 32 over the die 10 and a transparent cover 40 in the opening 32. The optics unit 50 can include a lens 54 and other optical elements' to direct light through the opening 32 and toward the die 10.
The die 10 includes an image sensor 12 and a plurality of bond-pads 14 electrically coupled to the image sensor 12. The interposer substrate 20 is a dielectric member having a plurality of interior pads 22, a plurality of ball-pads 24, and a plurality of traces 26 electrically coupling the interior pads 22 to corresponding ball-pads 24. The ball-pads 24 are arranged in an array for surface mounting the imager 1 to a board or module of another device. The bond-pads 14 on the die 10 are electrically coupled to corresponding interior pads 22 on the interposer substrate 20 by a plurality of wire-bonds 28 to provide electrical pathways between the bond-pads 14 and the ball-pads 24.
One problem with conventional packaged microelectronic imagers is that they have relatively large footprints and occupy a significant amount of vertical space (i.e., high profiles). For example, the footprint of the imager 1 in FIG. 1 is the surface area of the bottom of the interposer substrate 20, which is significantly larger than the surface area of the die 10. Accordingly, the footprint of conventional packaged microelectronic imagers can be a limiting factor in the design and marketability of picture cell phones or PDAs because these devices are continually shrinking to be more portable. Therefore, there is a need to provide microelectronic imagers with smaller footprints and lower vertical profiles.
Another problem with conventional microelectronic imagers is the manufacturing costs for packaging the dies. For example, forming the wire-bonds 28 on the imager 1 shown in FIG. 1 is complex and expensive because it requires connecting an individual wire between each bond-pad 14 on the die 10 and a corresponding interior pad 22 on the interposer substrate 20. In addition, it may not be feasible to form wire-bonds for the high-density, fine-pitch arrays of some high-performance devices. Therefore, there is a significant need to enhance the efficiency and reliability of packaging microelectronic imagers.

## Lesson: Microelectronic Imagers
### Section 1: Introduction
Microelectronic imagers are devices that capture and convert light into electrical signals. These signals are then processed by a computer to create digital images. Microelectronic imagers are used in digital cameras, wireless devices with picture capabilities, and many other applications. Cell phones and Personal Digital Assistants (PDAs), for example, incorporate microelectronic imagers for capturing and sending digital images.
### Section 2: Types of Microelectronic Imagers
There are three types of microelectronic imagers: CCD, CMOS, and other systems. CCD image sensors have been widely used in digital cameras and other applications. CMOS image sensors are also becoming very popular because they have low production costs, high yields, and small sizes. CMOS image sensors provide these advantages because they are manufactured using technology and equipment developed for fabricating semiconductor devices. CMOS image sensors are also more energy-efficient than CCD image sensors. Other systems of microelectronic imagers include infrared imagers, X-ray imagers, and ultrasonic imagers.
### Section 3: How Microelectronic Imagers Work
Microelectronic imagers work by capturing light and converting it into electrical signals. This is done by an array of photodiodes that are covered by a color filter. When light hits the photodiodes, it is absorbed and generates an electrical charge. This charge is then converted into a digital signal by an analog-to-digital converter. The digital signal is then processed by a computer to create a digital image.
### Section 4: Applications of Microelectronic Imagers
Microelectronic imagers are used in many different applications, including digital cameras, wireless devices with picture capabilities, medical imaging, security systems, and automotive imaging. They are also used in scientific research and space exploration.
### Section 5: Conclusion
Microelectronic imagers are essential components of modern electronic devices. They allow us to capture and share images with others quickly and easily. By understanding how microelectronic imagers work and their different types, we can appreciate their importance in our daily lives.

Lesson: Introduction to Music Production

## Section 1: Theoretical Concepts

In this lesson, we will learn about music production and its role in creating and recording music. Music production is the process of creating, recording, and editing music. It involves several steps, including composing, arranging, recording, mixing, and mastering.

## Section 2: Practical Examples

Let's take a look at an example of music production. Imagine you are producing a song for a pop artist. You start by composing the melody and chords on a piano or keyboard. Then, you arrange the song by adding different instruments such as drums, bass, and guitar. Next, you record the instruments using a digital audio workstation (DAW) such as Ableton Live or Logic Pro. After recording, you mix the song by adjusting the levels of each instrument and adding effects such as reverb and compression. Finally, you master the song by ensuring it sounds good on all playback systems.

## Section 3: Real-World Scenarios

Now let's apply what we've learned to a real-world scenario. Suppose you are producing a song for a band. You start by recording the band's performance live in a studio. Then, you edit the recording by removing mistakes and improving the overall sound quality. Next, you add effects such as reverb and delay to enhance the song's atmosphere. After mixing, you master the song to ensure it sounds good on all playback systems. Finally, you release the song on streaming platforms such as Spotify or Apple Music.

Lesson: Vaginal Rejuvenation - Understanding the Basics

Introduction:
Vaginal rejuvenation is a cosmetic procedure that aims to tighten and rejuvenate the vaginal area. This procedure is becoming increasingly popular among women who want to improve their sexual health and overall well-being. In this lesson, we will explore the basics of vaginal rejuvenation, including what it is, how it works, and what to expect during the procedure.

What is Vaginal Rejuvenation?

Vaginal rejuvenation is a cosmetic procedure that involves the use of lasers to tighten and rejuvenate the vaginal area. This procedure can help improve sexual function, reduce urinary incontinence, and enhance overall vaginal health. The procedure is typically performed on an outpatient basis under local or general anesthesia.

How does Vaginal Rejuvenation work?

Vaginal rejuvenation works by using laser energy to heat up the collagen and elastin fibers in the vaginal wall. This heat causes the fibers to contract, which in turn tightens the vaginal area. The procedure also stimulates the production of new collagen and elastin fibers, which further improves the overall health of the vaginal tissue.

What to expect during the procedure?

During the procedure, you will be asked to lie down on a table and will be given medication to help you relax.

[The expression and significance of microtubule - driven protein KIF2A in epithelial ovarian cancer].
Objective: To investigate the protein and mRNA expression of KIF2A in ovarian cancer, and to investigate the migration and invasion ability changes in ovarian cancer cell line HO-8910 transfected by KIF2A-siRNA. Methods: Immunohistochemical method was used to detect the expression of KIF2A in 30 cases of ovarian cancer and 20 cases of ovarian normal tissues. The expression of KIF2A mRNA was detected by RT-PCR. The mRNA and protein expression of KIF2A in cell line HO-8910 was detected by RT-PCR and Western blot after transfected by KIF2A-siRNA in vitro. After the transfection, the cell migration and invasion ability were observed by scratch test and transwell experiments. Result: The expression of KIF2A mRNA and protein in HO-8910 was significantly lower than that in normal ovarian tissue (P<0.05). The capacities of migration and invasion of HO-8910 was suppressed notably after the knockdown of KIF2A (P<0.05). Conclusion: KIF2A gene expression was increased in ovarian cancer, and knockdown of KIF2A gene can inhibit the migration and invasion of ovarian cancer cells. It suggested that KIF2A gene may be a new target for the development of ovarian cancer.

Lesson: Understanding Microtubules and their Role in Cancer Cell Migration and Invasion

Introduction: Microtubules are dynamic, filamentous structures composed of tubulin proteins that play a crucial role in maintaining cell shape, intracellular transport, and cell division. They are also involved in cell migration and invasion, which are essential processes during tumor metastasis. In this lesson, we will explore the role of microtubules in cancer cell migration and invasion, with a specific focus on the protein KIF2A, which is a motor protein that interacts with microtubules to facilitate cell movement.

Section 1: Microtubules and their Functions

Topic 1: Composition and Structure of Microtubules
- Microtubules are composed of tubulin proteins (α-tubulin and β-tubulin) that polymerize to form long, cylindrical structures.
- Microtubules have a hollow, cylindrical structure with a diameter of about 25 nm.

Topic 2: Functions of Microtubules
- Microtubules play a vital role in maintaining cell shape and providing structural support.
- They also serve as tracks for motor proteins, such as KIF2A, to move along and transport organelles and vesicles within the cell.
- Microtubules are essential for cell division, as they form the mitotic spindle during mitosis.

Section 2: KIF2A and its Role in Cancer Cell Migration and Invasion

Topic 1: KIF2A and Its Interaction with Microtubules
- KIF2A is a motor protein that interacts with microtubules to facilitate cell movement.
- KIF2A moves along the microtubules by using energy from ATP hydrolysis to change its conformation, which allows it to "walk" along the microtubules.

Topic 2: KIF2A Expression in Ovarian Cancer
- Studies have shown that KIF2A is overexpressed in ovarian cancer cells compared to normal ovarian cells.
- This overexpression is associated with increased cell migration and invasion, which are hallmarks of metastatic cancer cells.

Section 3: Experimental Evidence for the Role of KIF2A in Cancer Cell Migration and Invasion

Topic 1: Knockdown of KIF2A Suppresses Migration and Invasion in Ovarian Cancer Cells
- By using KIF2A-specific siRNA, researchers have successfully knocked down KIF2A expression in ovarian cancer cells.
- This knockdown resulted in a significant decrease in cell migration and invasion, as observed by wound healing assays and transwell assays.

Topic 2: KIF2A Interacts with Actin Filaments to Facilitate Cell Movement
- KIF2A has been shown to interact with actin filaments, which are essential components of the cytoskeleton involved in cell movement.
- This interaction suggests that KIF2A may play a role in coordinating microtubule and actin dynamics during cell migration and invasion.

Conclusion: Understanding the role of microtubules and their associated proteins, such as KIF2A, in cancer cell migration and invasion is crucial for developing targeted therapies to prevent or treat metastatic cancer. By understanding the molecular mechanisms underlying these processes, researchers can identify potential targets for therapeutic intervention and develop strategies to disrupt the migration and invasion of cancer cells.

Glossary:
- Microtubules: Dynamic, filamentous structures composed of tubulin proteins that play a crucial role in maintaining cell shape, intracellular transport, and cell division.
- KIF2A: A motor protein that interacts with microtubules to facilitate cell movement.
- Overexpression: The presence of an abnormally high amount of a specific gene product, often resulting from genetic mutations or chromosomal rearrangements.
- Metastasis: The process by which cancer cells spread from the primary tumor to other parts of the body, often leading to the formation of secondary tumors.
- Cytoskeleton: A network of protein filaments that provides structural support and helps maintain cell shape, as well as playing a role in cell movement and division.

Pulmonary hypertension in congenital diaphragmatic hernia patients: Prognostic markers and long-term outcomes.
Prenatal observed/expected lung-to-head ratio (O/E LHR) by ultrasound correlates with postnatal mortality for congenital diaphragmatic hernia (CDH) patients. The aim of this study is to determine if O/E LHR correlates with pulmonary hypertension (PH) outcomes for CDH patients. A single center retrospective chart review was performed for CDH neonates from January 1, 2006, to December 31, 2015, (REB #1000053124) to include prenatal O/E LHR, liver position, first arterial blood gas, repair type, echocardiogram (ECHO), and lung perfusion scan (LPS) results up to 5years of age. Of 153 newborns, 123 survived (80.4%), 58 (37.9%) had prenatal O/E LHR, and 42 (27.5%) had postnatal ECHO results. High mortality risk neonates (O/E LHR ≤45%) correlated with higher right ventricular systolic pressure (RVsp) at birth. Generally PH resolved by age 5years. LPS results did not change over time (p>0.05) regardless of initial PH severity, suggesting that PH resolution did not correlate with increased ipsilateral lung perfusion to offload the right ventricle. Prenatal prognostic markers correlated with initial PH severity for CDH newborns, but PH resolved over time despite fixed perfusion bias to the lungs. These results suggest favorable PH outcomes for CDH patients who survive beyond infancy. Retrospective Cohort Study. 3b.

Lesson: Introduction to Pulmonary Hypertension in Congenital Diaphragmatic Hernia Patients
Objective: To introduce the concept of pulmonary hypertension (PH) in congenital diaphragmatic hernia (CDH) patients and its prognostic markers and long-term outcomes.
Overview: Pulmonary hypertension is a condition where the blood pressure in the lungs is abnormally high. This can occur in congenital diaphragmatic hernia patients due to lung hypoplasia or other factors. In this lesson, we will explore the prognostic markers and long-term outcomes of PH in CDH patients.
Section 1: Introduction to Pulmonary Hypertension
- Definition: Pulmonary hypertension is a condition where the blood pressure in the lungs is abnormally high.
- Causes: Pulmonary hypertension can be caused by various factors such as lung disease, heart disease, or other medical conditions.
- Symptoms: Symptoms of pulmonary hypertension may include shortness of breath, fatigue, chest pain, and fainting.
Section 2: Prognostic Markers for Pulmonary Hypertension in CDH Patients
- Prenatal Observed/Expected Lung-to-Head Ratio (O/E LHR): Prenatal O/E LHR by ultrasound correlates with postnatal mortality for CDH patients.
- Liver Position: The position of the liver can also be a prognostic marker for PH in CDH patients.
- First Arterial Blood Gas: This test measures the oxygen and carbon dioxide levels in the blood and can help determine the severity of PH.
- Repair Type: The type of repair performed on the CDH patient can also be a prognostic marker for PH.
- Echocardiogram (ECHO): An echocardiogram can help determine the pressure in the right ventricle, which can be a prognostic marker for PH.
- Lung Perfusion Scan (LPS): This test can help determine the blood flow to the lungs and can be a prognostic marker for PH.
Section 3: Long-Term Outcomes of Pulmonary Hypertension in CDH Patients
- Generally, PH resolves by age 5 years in CDH patients.
- However, some patients may experience long-term complications such as heart failure or other lung-related issues.
Section 4: Conclusion
- Pulmonary hypertension can be a serious complication for CDH patients, but with proper monitoring and treatment, most patients can recover well.
- Understanding the prognostic markers and long-term outcomes of PH in CDH patients can help healthcare providers make informed decisions about treatment and care.
