This document summarizes common circulatory and respiratory diseases. For circulatory diseases, it describes coronary artery disease where plaque builds up in the arteries supplying the heart, restricting blood flow and potentially causing angina, heart failure, or heart attack. It then focuses on heart attack, explaining it occurs when heart muscle dies from reduced blood supply due to blocked arteries from plaque or blood clots. For respiratory diseases, it outlines asthma where airways constrict during attacks, reducing airflow, and then bronchiectasis where damaged lung tissue leads to impaired structure and function from chronic infection and inflammation.

CHAPTER 12: Cardiovascular Disease, Diabetes, and
Cancer
Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood
vessels. Cardiovascular disease includes coronary artery diseases (CAD) such
as angina and myocardial infarction (commonly known as a heart attack). Other
CVDs include stroke, heart failure, hypertensive heart disease, rheumatic heart
disease, cardiomyopathy, heart arrhythmia, congenital heart disease, valvular heart
disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic
disease, and venous thrombosis.
The underlying mechanisms vary depending on the disease. Coronary artery
disease, stroke, and peripheral artery disease involve atherosclerosis, which is the
narrowing of the inside of an artery due to the build up of plaque. This may be
caused by high blood pressure, smoking, diabetes, lack of exercise, obesity, high
blood cholesterol, poor diet, and excessive alcohol consumption, among others. High
blood pressure results in 13% of CVD deaths, while tobacco results in 9%, diabetes
6%, lack of exercise 6% and obesity 5%. Rheumatic heart disease may follow
untreated strep throat. It is estimated that 90% of CVD is preventable.
Coronary heart disease (CHD), also commonly referred to as just heart disease, is a
common term for the buildup of plaque in the heart’s arteries that could lead to
heart attack. But is there a difference between coronary heart disease and coronary
artery disease? The short answer is often no — health professionals frequently use
the terms interchangeably. However, coronary heart disease, or CHD, is actually a
result of coronary artery disease, or CAD. With coronary artery disease, plaque first
grows within the walls of the coronary arteries until the blood flow to the heart’s
muscle is limited. View an illustration of coronary arteries below:
Coronary Arteries
The Coronary Arteries are the blood vessels that supply blood to your heart. They
branch off of the aorta at its base. The right coronary artery, the left main coronary, the
left anterior descending, and the left circumflex artery, are the four major coronary
arteries. Blockage of these arteries is a common cause of angina, heart disease, heart
attacks and heart failure.
This restriction of the blood supply to the tissues is also called ischemia. It may be
chronic, narrowing of the coronary artery over time and limiting of the blood supply
to part of the muscle. Or it can be acute, resulting from a sudden rupture of a plaque
and formation of a thrombus or blood clot.
Anatomy of the Cardiovascular System
To fully understand Cardiovascular Diseases, it may be helpful to understand the
anatomy of the cardiovascular system. It includes the following:
o Heart: the pump, divided into four chambers (R/L atria, R/L ventricles)
o Arteries: large vessels carrying oxygen-rich blood away from heart; have
thick, muscular wall
o Arterioles: smaller arteries
...
This presentation provides a knowledge about Ischemic heart Disease, Ischemia, Mechanism of Action, signs and symptoms, Causes of Ischemia, Ischemia in different body parts, Angina, Myocardial Infarction, Artherosclerosis, Drugs used to treat ischemia and recent discovery related to Cardiac ischemia. An assignment for the subject, Advanced Pharmacology-I, 1st year M.Pharm, 1st semester.
Myocardial infarction is the medical name of a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.Symptoms include tightness or pain in the chest, neck, back or arms, as well as fatigue, lightheadedness, abnormal heartbeat and anxiety. Women are more likely to have atypical symptoms than men.
Treatment ranges from lifestyle changes and cardiac rehabilitation to medication, stents, and bypass surgery.
heart failure otherwise called congestive heart failure. causes of this is diabetes Mellitus, hypertension, excess intake of fat, stress, prevention of this according to the doctor's order take the medicine, follow a diet plan, without sodium, alcohol, should be avoided.then we free from congestive heart failure .

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. • Coronary
Artery Disease
Occurs when a substance
called plaque builds up in
the arteries that supply
blood to the heart (called
coronary arteries). Plaque
is made up
of cholesterol deposits,
which can accumulate in
your arteries. When this
happens, your arteries can
narrow over time. This
process is called
atherosclerosis.
4. Plaque buildup can cause angina, the most common
symptom of CAD. This condition causes chest pain or
discomfort because the heart muscle doesn't get
enough blood. Over time, CAD can weaken the heart
muscle. This may lead to heart failure, a serious
condition where the heart can't pump blood the way
that it should. An irregular heartbeat, or arrhythmia,
can also develop.
For some people, the first sign of CAD is a heart
attack. A heart attack occurs when plaque totally
blocks an artery carrying blood to the heart. It also can
happen if a plaque deposit breaks off and clots a
coronary artery.
5. HEART ATTACK
• A heart attack, also called a
myocardial infarction, occurs
when a section of the heart
muscle dies or gets damaged
because of reduced blood
supply. Coronary Artery
Disease (CAD) is the main
cause of heart attack. A less
common cause is a severe
spasm of a coronary artery,
which also can prevent
blood supply from reaching
the heart.
6. • It is important to seek treatment for a
heart attack immediately. Otherwise,
further damage to the heart muscle can
occur and an irregular heart rhythm may
develop.
• Sudden cardiac arrest—the stopping of
the heart—occurs when the heart stops
completely. Unless treated, a person
whose heart has stopped can die within
minutes.
7. •Treatment
• People who experience a heart attack need emergency
care such as cardiopulmonary resuscitation (CPR) or
electrical shock (defibrillation). That's why you need to
act quickly once you notice the signs and symptoms of
heart attack.
• If you think you or someone you know is having a heart
attack, call 9-1-1 immediately. Bystanders who have
been trained to perform CPR or use a defibrillator may
be able to help the victim until emergency medical
personnel arrive. At the hospital, doctors can perform
tests to determine whether a heart attack is occurring
and decide on the best treatment.
9. ASTHMA
• Asthma is a serious condition in
which the small airways of the
affected person's lungs suddenly
constrict when they are exposed to
certain triggers, such as dust
mites,pollen, exercise, or even dry air.
During an asthma 'attack', the
person's airway lining rapidly
becomes inflamed and swollen, the
muscles around the airways tighten,
and excess mucus is produced as the
body reacts to the trigger. This
reaction causes reduced airflow into
and out of the lungs, and the person
has to gasp for breath.
10. BRONCHIECTASIS
• Bronchiectasis is a progressive lung
disease, affecting 600,000 people
worldwide. It is often mistaken for
asthma or pneumonia and misdiagnosis is
common.In this disease the airway walls
are chronically inflamed, with poor
clearing of the increased mucus
production. Chronic inflammation of the
walls of the airway is common to all types
of bronchiectasis. This is often a result of
a vicious cycle of bacterial infection, in
which damage to the lungs further
predisposes the lung to more infections.
The body repairs the damaged lung tissue
by forming tough,fibrous material, which
leads to changes that impair normal lung
structure and function
11. • Effects include:
• Reduced lung capacity;
• Poor gas-exchange;
• Changes of the organisation of blood vessels; and
• Overall increased blood flow through the lungs.
• These changes can ultimately lead to heart
failure. Recurrent lung infections commonly
reduce patients' quality of life; progressive
respiratory insufficiency is the most common
cause of death.Most cases of bronchiectasis
develop during childhood, and can be a result of
infections such as pneumonia or the inhalation of
noxious substances.
