Lesson: Understanding Carotid Endarterectomy

**Introduction:**

Carotid endarterectomy is a surgical procedure used to treat carotid artery disease, a condition in which plaque builds up in the arteries of the neck. This buildup can narrow the arteries, reducing blood flow to the brain and increasing the risk of stroke. In this lesson, we will learn about the procedure, its indications, and how it is performed.

**Section 1: What is Carotid Endarterectomy?**

Carotid endarterectomy is a surgical procedure used to remove plaque from the carotid arteries of the neck. These arteries are responsible for supplying blood to the brain. The procedure is typically performed on patients with carotid artery disease, a condition in which plaque builds up in the arteries, narrowing them and increasing the risk of stroke.

**Section 2: When is Carotid Endarterectomy Indicated?**

Carotid endarterectomy is indicated for patients with carotid artery disease who have symptoms such as transient ischemic attacks (TIAs) or strokes. It may also be recommended for patients who have significant plaque buildup in their carotid arteries but do not yet have symptoms, but are at high risk of developing them.

**Section 3: How is Carotid Endarterectomy Performed?**

Carotid endarterectomy is typically performed in a hospital under general or local anesthesia. The patient is placed on their back with their head elevated and supported by a specialized headrest. A small incision is made in the neck, just above the collarbone. The surgeon then makes an opening in the artery wall and removes the plaque using specialized instruments. The artery is then repaired, and the incision is closed with stitches.

**Section 4: Complications and Risks**

As with any surgical procedure, there are risks associated with carotid endarterectomy. These risks include bleeding, infection, and damage to the nerves in the neck. There is also a small risk of stroke or heart attack during the procedure. However, these risks are generally low when the procedure is performed by an experienced surgeon.

**Section 5: Conclusion**

In conclusion, carotid endarterectomy is a valuable procedure for treating carotid artery disease. By removing plaque from the carotid arteries, the procedure can improve blood flow to the brain and reduce the risk of stroke. This lesson has provided an overview of the procedure, its indications, and how it is performed. By understanding the basics of carotid endarterectomy, patients can make informed decisions about their treatment options.

text: On days like today when I have absolutely no time to write, I will post a random poem from my childhood. Here is a poem written by my father when I was in the fifth grade.. Monster. The monster was scary.. It had big, bloody claws.. It reached out toward Mary,. So I yelled, "Help us, Pa!". Pa came in running. With shotgun in tow.. He pointed it at the beast,. And boy, did it blow!. There were monster guts everywhere,. From ceiling to floor.. It took days just to clean up. The stuff off the door.. If I recall correctly, I began the first line of the poem and left to go to the bathroom or something, and when I returned, there was this in its stead. I think I was traumatized for months after this.. I will write something tomorrow. I will.

SUMO fusion system facilitates soluble expression and high production of bioactive human fibroblast growth factor 23 (FGF23).
As a key humoral regulator of phosphate homeostasis and its involvement in the pathogenesis of human disease, human fibroblast growth factor 23 (hFGF23) has become a particularly attractive therapeutic target. To prepare soluble and bioactive recombinant human FGF23 to meet the increasing demand in its pharmacological application, small ubiquitin-related modifier (SUMO)-FGF23 fusion gene and FGF23 non-fusion gene were amplified by standard PCR methods and cloned into vector pET-22b and pET-3c, then transformed into Escherichia coli Rosetta (DE3) and BL21 (DE3). The best combination of plasmid and host strain was screened, and only Rosetta (DE3)/pET-SUMO-FGF23 was screened for rhFGF23 protein expressed. The average bacterial yield and the soluble expression level of recombinant hFGF23 of three batches attained 687 ± 18 g and 30 ± 1.5%, respectively, after treatment with 0.4 mM isopropyl-thio-β-galactopyranoside for 19 h at 16 °C in a 30-L fermentor, after which it was purified by DEAE Sepharose FF and nickel nitrilotriacetic acid affinity chromatography. Once cleaved by the SUMO protease, the recombinant human FGF23 was released from the fusion protein. The purity of rFGF23 was shown by high performance liquid chromatography to be greater than 90% and the yield was 60 ± 1.5 mg/L. In vitro data showed that the purified rFGF23 can induce the phosphorylation of mitogen-activated protein kinases in the glioma U251 cell. The results of in vivo animal experiments also showed that rFGF23 could decrease the concentration in the plasma of normal rats fed with a fixed formula diet.

Proteins are essential macromolecules that perform various functions in living organisms. They are involved in metabolism, DNA replication, immune response, and many other biological processes. In this lesson, we will learn about protein expression and purification, which are crucial techniques used to produce large quantities of a specific protein for further study or application.

Section 1: Protein Expression

Topic 1: Gene Cloning and Amplification
- Definition: Gene cloning is the process of making multiple copies of a gene, while gene amplification is the process of increasing the number of copies of a gene.
- Example: In this study, the researchers used gene cloning to create a plasmid containing the SUMO-FGF23 fusion gene.

Topic 2: Host Strains and Expression Systems
- Definition: A host strain is a type of microorganism (e.g., bacteria, yeast, or insect cells) used to produce a specific protein. An expression system is a set of conditions that allow a host strain to produce a particular protein.
- Example: In this study, the researchers used E. coli Rosetta (DE3) as the host strain and pET-22b and pET-3c vectors as the expression systems.

Topic 3: Protein Solubility and Fusion Tags
- Definition: Solubility refers to the ability of a protein to dissolve in a solution, while fusion tags are short peptide sequences that can be added to a protein to improve its solubility and stability.
- Example: In this study, the researchers used a SUMO fusion tag to improve the solubility of the recombinant hFGF23 protein.

Section 2: Protein Purification

Topic 1: Chromatography Techniques
- Definition: Chromatography is a laboratory technique used to separate mixtures of compounds based on their properties. There are several types of chromatography, including ion exchange chromatography, affinity chromatography, and size exclusion chromatography.
- Example: In this study, the researchers used affinity chromatography to purify the recombinant hFGF23 protein.

Topic 2: Buffer Systems and pH Optimization
- Definition: A buffer system is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid, which resists changes in pH. pH optimization refers to adjusting the pH of a solution to optimize the activity of a protein.
- Example: In this study, the researchers optimized the pH of the buffer system to maximize the activity of the recombinant hFGF23 protein.

Conclusion:
In this lesson, we learned about protein expression and purification, two essential techniques used to produce large quantities of a specific protein for further study or application. We covered topics such as gene cloning and amplification, host strains and expression systems, protein solubility and fusion tags, chromatography techniques, buffer systems, and pH optimization.

**Lesson: How to Use Medical Databases**

**Introduction**

In this lesson, we will learn how to use medical databases to find information about diseases, treatments, and medications. We will use the example of the U.S. National Library of Medicine's database, which contains clinical and biomedical literature.

**Section 1: Understanding Medical Databases**

A medical database is a collection of information about medicine, health, and related fields. It can include articles from scientific journals, books, reports, and other sources. These databases are designed to help researchers, doctors, and other healthcare professionals find the information they need quickly and easily.

**Section 2: Searching Medical Databases**

To search a medical database, you need to know what you are looking for. Start by identifying the keywords that describe your topic. For example, if you are looking for information on diabetes, your keywords might include "diabetes," "insulin," "blood sugar," and "treatment."

Once you have identified your keywords, you can use the database's search function to find articles that contain those words. Most databases have a search box where you can enter your keywords. You can also use advanced search options to narrow down your results by publication date, language, and other criteria.

**Section 3: Evaluating Medical Databases**

Not all medical databases are created equal. Some are more comprehensive than others, and some focus on specific areas of medicine. To evaluate a database, you should consider the following factors:

- Coverage: Does the database cover the topic you are interested in?
- Sources: What types of sources does the database include? Are they reputable?
- Updates: How often is the database updated?
- Accessibility: Is the database available for free or do you need to pay for access?

**Section 4: Analyzing Medical Databases**

Once you have found articles that relate to your topic, you need to analyze them to determine their relevance and credibility. Here are some questions you can ask when analyzing an article:

- Who wrote the article? Are they an expert in the field?
- When was the article published? Is it up-to-date?
- What is the article's purpose? Is it to inform, persuade, or entertain?
- Are the sources cited in the article reliable?

**Section 5: Applying Skills to New Problems**

Now that you know how to use medical databases, you can apply these skills to other areas of your life. For example, you can use similar techniques to find information on other topics, such as politics, economics, or history. By learning how to critically evaluate sources and analyze information, you will become a better researcher and thinker.

**Conclusion**

In this lesson, we learned how to use medical databases to find information about diseases, treatments, and medications. We covered topics such as understanding medical databases, searching and evaluating medical databases, analyzing medical databases, and applying these skills to new problems. By following these steps, you can become a skilled researcher and find the information you need quickly and easily.

Most political junkies who have some gray in their hair can easily think of another Democratic presidential nominee who was one – Massaschusetts Gov. Michael Dukakis, who lost as an incumbent to Ed King in 1978, and was re-elected in 1982, and 1986. Perhaps his loss to George H.W. Bush in 1988 still smarts too much for the memory banks.. It’s also not true that “everyone figured Clinton was through” when he lost in 1980. He was 34, and Team Clinton wasn't about to let anyone shovel dirt on his ambition.

Lesson Title: Understanding the Predictors of Somatic BRAF Mutations in Colorectal Cancer

Introduction:
Colorectal cancer is a common type of cancer that affects the colon and rectum. It is estimated that about 1 in 20 people will develop colorectal cancer in their lifetime. In recent years, researchers have identified several genetic mutations that are associated with an increased risk of developing colorectal cancer. One such mutation is the BRAF gene, which is involved in cell growth and division. In this lesson, we will explore the predictors of somatic BRAF mutations in colorectal cancer, including smoking, gender, and ethnicity.

Section 1: Understanding Somatic Mutations

What are somatic mutations?
Somatic mutations are changes in the DNA that occur during a person's lifetime. These mutations can be inherited from our parents or acquired during our lifetime due to exposure to environmental factors, such as radiation or chemicals. In the context of colorectal cancer, somatic mutations refer to mutations that occur in the cells of the colon or rectum.

What is the BRAF gene?
The BRAF gene is a type of oncogene, which means it has the potential to cause cancer. The BRAF gene encodes a protein called the B-Raf proto-oncogene serine/threonine kinase. This protein is involved in regulating cell growth and division. When the BRAF gene is mutated, it can lead to uncontrolled cell growth and the development of cancer.

Section 2: Predictors of Somatic BRAF Mutations in Colorectal Cancer

What is the relationship between smoking and somatic BRAF mutations in colorectal cancer?
Smoking has been identified as a risk factor for the development of colorectal cancer. Studies have shown that smokers are more likely to develop colorectal cancer than non-smokers. Additionally, smoking has been linked to an increased risk of somatic BRAF mutations in colorectal cancer. This suggests that smoking may play a role in the development of these mutations.

What is the relationship between gender and somatic BRAF mutations in colorectal cancer?
Gender has also been found to be a predictor of somatic BRAF mutations in colorectal cancer. Men are more likely to develop colorectal cancer than women, and they are also more likely to have somatic BRAF mutations. This suggests that there may be differences in the way men and women respond to environmental factors that contribute to the development of colorectal cancer and somatic BRAF mutations.

What is the relationship between ethnicity and somatic BRAF mutations in colorectal cancer?
Ethnicity has been found to be another predictor of somatic BRAF mutations in colorectal cancer. African Americans are more likely to develop colorectal cancer than other ethnic groups, and they are also more likely to have somatic BRAF mutations. This suggests that there may be differences in the way different ethnic groups respond to environmental factors that contribute to the development of colorectal cancer and somatic BRAF mutations.

Section 3: Conclusion

In conclusion, smoking, gender, and ethnicity are all predictors of somatic BRAF mutations in colorectal cancer. Understanding these predictors can help us identify individuals who are at a higher risk of developing colorectal cancer and somatic BRAF mutations. This information can be used to develop targeted screening and prevention strategies to reduce the incidence of colorectal cancer and improve patient outcomes.

Glossary:
- Somatic mutations: Changes in the DNA that occur during a person's lifetime.
- Oncogene: A gene that has the potential to cause cancer.
- BRAF gene: A type of oncogene that encodes a protein involved in regulating cell growth and division.
- Somatic BRAF mutations: Mutations in the BRAF gene that occur in the cells of the colon or rectum.
- Colorectal cancer: A type of cancer that affects the colon and rectum.

Conclusion:
In this lesson, we have explored the predictors of somatic BRAF mutations in colorectal cancer, including smoking, gender, and ethnicity. We have learned that these factors can influence the development of colorectal cancer and somatic BRAF mutations. By understanding these predictors, we can develop targeted screening and prevention strategies to reduce the incidence of colorectal cancer and improve patient outcomes.

Classical Convert describes Ben's new discovery of classical music, having only started listening when he was 23. He also maintains a larger website with advice for newcomers to the classical world.. the search for artistry is Phil Giampietro's blog on (duh!) the search for artistry in music. He's also a euphonium player.. The Sibelian Conspiracy is a group blog by composers to promote their music. There is some discrepancy in the mission, since the subtitle of the blog is "about music, art, and literature.". 3 comments:. "...the search for artistry in music. He's also a euphonium player.". Somehow, that makes me smile!. :-). Thanks very much for the link :). it's less of a "search" and more of a "fumbling about in the dark," which would have been quite a long title.. glad to see that the euphonium makes someone smile ;-)

Lesson: Understanding Music Theory

Introduction:
Music theory is the study of how music works. It provides a framework for understanding the structure, harmony, and composition of music. In this lesson, we will explore the basic principles of music theory, including scales, chords, and intervals. We will also learn how to read sheet music and apply these principles to real-world scenarios.

Section 1: Scales
A scale is a set of notes that are played in a specific order. There are many different types of scales, but they all share some common characteristics.

The first thing to know about scales is that they have a root note. This is the note that determines the name of the scale. For example, if we start on the note C, we are playing a C major scale.

Scales also have a pattern of intervals, or distances between notes. A major scale, for example, has a pattern of two semitones, two tones, and one tone. This means that if we start on a note and count up two semitones, two tones, and one tone, we will end on the next note in the scale.

There are other types of scales as well, such as minor, pentatonic, and blues scales. These scales have different patterns of intervals, but they still follow the same basic rules.

Exercise: Play a major scale on your instrument. Make sure you start on the correct note and play the notes in the correct order.

Section 2: Chords
A chord is a group of notes that are played together. Just like scales, there are many different types of chords, but they all share some common characteristics.

The first thing to know about chords is that they have a root note. This is the note that determines the name of the chord. For example, if we play a C major chord, the root note is C.

Chords also have intervals, just like scales. A major chord, for example, has a pattern of two semitones, three tones, and one tone. This means that if we play a note and then add another note that is two semitones higher, followed by another note that is three tones higher, and finally another note that is four semitones higher, we will have played a C major chord.

There are other types of chords as well, such as minor, diminished, and augmented chords. These chords have different patterns of intervals, but they still follow the same basic rules.

Exercise: Play a major chord on your instrument. Make sure you play the notes in the correct order and that the root note is clear.

Section 3: Intervals
An interval is the distance between two notes. There are many different types of intervals, but they all share some common characteristics.

The first thing to know about intervals is that they have a number value. This value is determined by the number of semitones between the two notes. For example, if we play two notes that are two semitones apart, we have an interval of a second.

Intervals also have a quality, or type. There are three types of intervals: major, minor, and perfect. A major interval is one that is made up of two tones and one semitone. A minor interval is one that is made up of one tone and two semitones. A perfect interval is one that is made up of two tones and two semitones.

Exercise: Identify the intervals in the following sequence: C D E F G A B. Use the number value and quality to describe each interval.

Conclusion:
In this lesson, we learned about the basic principles of music theory, including scales, chords, and intervals. We learned how to read sheet music and apply these principles to real-world scenarios. By understanding these concepts, we can better appreciate and analyze the structure and harmony of music.

C/S Nexans Skagerrak Ready to put to Sea After Major Conversion and Upgrade Project

Nexans, global leader in cables and cabling solutions, has further
extended the subsea cable laying capabilities of the C/S Nexans Skagerrak,
already one of the world’s most advanced cable ships, following the
successful completion of a major conversion and upgrading project. It will
put to sea shortly from the Cammell Laird Shiprepairers and Shipbuilders
Limited dockyard in Birkenhead, England where the 8 million euro, two-month,
fast-track contract was carried out.

The conversion and upgrade has increased the C/S Nexans Skagerrak’s
capability to carry out even larger scale power cable and umbilical
installation projects, to meet the changing needs of customers in the subsea
interconnector and oil & gas sectors. It has also extended her service life
and increased her autonomy while at sea.

The major element in the project has been the insertion of a new 12.5
metre pre-fabricated hull section that has increased the ship’s overall
length to 112.25 metres. An additional accommodation module has also been
installed, taking the total number of single cabins on board to 60, together
with a new work deck, complete with cable-handling equipment, that has
increased on the on-deck storage capacity to around 2000 m2 (from 900 m2).
The upgrade has increased the ship’s deadweight from 7,886 tonnes to 9,373
tonnes.

“Owning and operating our own dedicated cable ship forms a vital part of
Nexans’ strategy to provide a comprehensive service for subsea projects, from
design, development and manufacture to installation”, says
Krister Granlie,
Managing Director of Nexans’ Umbilicals & Submarine High Voltage Business
Group. “This major upgrade and conversion of the C/S Skagerrak underlines our
commitment to the subsea sector, and ensures we are well prepared to handle
the growing market trend for ever longer cables and larger scale
installations.”

State-of-the-art cable laying ship

The C/S Nexans Skagerrak was the first purpose-built ship to be designed
specifically for the transport and installation of submarine high-voltage
power cables and umbilicals. To date, there are only two vessels of this kind
in the world. It features a 7,000 tonne capacity, 29 metre diameter
turntable, a computer based laying control system and a state-of-the-art
dynamic positioning system, and can also deploy Nexans’ specialist Capjet ROV
trenching systems for cable burial operations.

The ship can be fitted with additional cable handling equipment to
perform operations such as: cable repairs, including submarine cutting and
retrieval of damaged sections; simultaneous laying of two cables with
controlled separation; piggyback laying.

Past and future projects

Nexans operated the C/S Nexans Skagerrak on a long term charter basis for
many years, before purchasing her outright in 2006. She has been involved in
a variety of major submarine cable projects such as: both power links betweenSpain and Morocco (1997 and 2005); the Gemini project in the Gulf of Mexico
(1999); the Abu Safah project in Saudi Arabia (2004) and the NorNed link
(2008) between Norway and the Netherlands which, at 580 km, is the world’s
longest high-voltage submarine power link.

The first project for the C/S Nexans Skagerrak on leaving Birkenhead will
be the BP Valhall PFS (power from shore) project in the North Sea. This
involves the laying of 292 km of HVDC (high voltage direct current) cable, as
well as a separate optical fibre cable, to provide the Valhall offshore
platform with power generated onshore in Norway.

The Cammell Laird shipyard was selected for the C/S Nexans Skagerrak

text: The 1987 edition of the Ice Capades might have had great skaters like Torvill and Dean and Kitty and Peter Carruthers, but the real star of the show was a person in a costume playing the talking bear Teddy Ruxpin.. I did not see this version of the Ice Capades, but I did go to a few other ones and enjoyed them. The one part I always disliked is when they did the move, which you see in this commercial, where the one skater grabs their partner by the leg and whips them around, their head passing mere inches from the ice at high-speed. My Mother would always remark when seeing this on TV, “this is how people break their necks!” Since then just seeing this risky maneuver makes me anxious. All I can think about is the impending tragedy that will traumatize a generation of potential ice-based entertainment fans.. Less daredevils and more Teddy please!
