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

2. Tips for an Effective Scientific Presentation
• Know your audience
• appropriate introduction- clinical references great!
• appropriate amount of explanation and detail
• “Tell them what you are going to tell them, tell them,
tell them what you told them.”
• Can use outline, but only if necessary and helpful
• Hit on a few major points- CRUCIAL
• Title every slide with the point you are making! (ie the RESULT,
not the “effect of”)
3. Tips for an Effective Scientific Presentation
• Use high quality charts
• few words
• never less than size 18 font – know your room! (this is 22)
• large figures with readable axes and legends – know your room!
• avoid “overproduced” effects like fancy PowerPoint backgrounds
and distracting movement
• appropriate use of colors - use color for emphasis or clarity only
• use easily-seen colors such as red, blue and green: and test them on
the screen first (not the computer).
• Consider red/green color-blindness
4. Tips for an Effective Scientific Presentation
• Be aware of your actions
• don’t block screen in small room;
• don’t move constantly
• don’t speak with your back to audience – look at them, especially
at the key people (like your boss!)
• use a microphone if available – it will always help – if not, talk
loudly and forcefully
• don’t use a laser pointer, unless you can hold it very still: don’t
play with it!
5. Tips for an Effective Scientific Presentation
• Always stay within your allotted time- wrap up
immediately when the chairman indicates it is time to do so
• Answering questions
• be respectful, regardless of the tone of questioner – “That is a very
good question…”
• admit ignorance; avoid long rebuttals - “maybe we should discuss
it later”
• anticipate questions – have some extra slides for expected
questions
6. Tips for an Effective Scientific Presentation
• Speak from memory
• DO NOT read from overheads
• DO NOT read from a script
• Use a few notes to remind you of key words and transitions
between slides
• Practice repeatedly out loud; spend time working out the wording
on difficult sections and make sure timing is correct; re-order slides
if another order makes more sense
• Show energy and enthusiasm
• Try to minimize “uhs,” “ums,” and “likes”

Outline
1. Introduction
2. Experimental Methods
3. Results
4. Discussion
5. Conclusions
6. Future Work
(If you use this generic outline you will waste 45 s going through it and
aggravate your audience)
9. Ask Questions to Create Suspense
• First delineate the problem that arises (from other
people’s work or from your results)
• Then use a question slide: (“this led us to the
following question: what does x do to y?”)
• Only then show results (remember to explain the
method; if complicated, use another slide)
• Then confirmatory results
• Then a conclusion
• Talk should consist of several “story modules”
10. Always Provide a Rationale for
Your Experiments!
Do not show a “data collection”
11. 7B2 and ProSAAS Are Endogenous

• Then we did this
• I might add a diagram here if it makes the
method clearer
• So now you understand the general
approach to solving the question I posed

14. Conclusions
• This would be the place to write an
important take-home message
• Remember people’s attention span is limited
and if you put too much here they will
remember nothing
• Therefore, less is more
15. Furin as a Therapeutic Target
(rationale slide- why should the audience be interested in what I am going
to tell them?)
• Inhibition should destroy the biological function
of pathogenic substrates which require furin
processing for toxicity
• Inhibition should diminish activation of other
furin-activated enzymes (matrix metalloproteases)
• Inhibitors could be useful therapeutics in bacterial
disease and/or cancer
16. Testing D6R
(questions)
• Is D6R toxic?
• Is D6R efficiently transported into the cell?
• Can D6R affect furin-mediated processes in
a cellular setting?
– Pseudomonas exotoxin A (PEA) is cleaved by
furin in the endosomal pathway
– Cleavage by furin is required for PEA toxicity
– Can D6R block PEA toxicity?
17. Why Attempt to Find Other PC2
Inhibitors?
• PC2 is the enzyme responsible for the synthesis of
glucagon
• Glucagon acts in functional opposition to insulin
(whose synthesis is not PC2-dependent)
• Animals lacking PC2 have low blood sugar which
is raised by glucagon restoration
• Therefore, PC2-specific inhibitors might assist in
lowering blood sugar in diabetics
20. Use summary slides both within
the presentation and at the end
Limit the number of points you make!
21. Summary, Inhibitor Studies
•Both PC1 and PC2 possess potent
endogenous inhibitors; other convertases such
as furin are also likely to have endogenous
inhibitors
•The function of endogenous inhibitors may be
to control activity during intracellular transport
rather than during prohormone maturation
•Proprotein convertases- and in particular
furin- represent important therapeutic targets
22. Add human interest whenever
possible
•Create suspense by asking questions
•Describe any Eureka or unusual
moments you had while doing the
research
•Add humorous slides
•Relate your work to human disease

28. The 50 Minute Seminar vs the 10
Minute Meeting Talk
Rule of thumb is 1 min per slide (the
longer the talk, the more you can add
to this)
29. The Ten Minute Talk
• You must usually oversimplify
• You do not supply detailed information on
methods
• You show only about six pieces of actual
data
• All the standard elements (rationale, titling
of slides with findings, summary) are
present
30. NEVER- EVER!- go beyond 10
min or 50 min!
You will be perceived as 1) a bad
speaker; and 2) arrogant- why is your
time more important than the
audience’s?
32. General
• 200-300 words- MUST fit guidelines
• Persuades the reader that you did something
new and worthwhile
• Often the only published record of the work
(meetings) – until the paper appears
• Limit jargon and abbreviations; no citations
• Polished: elegant, clear sentences which are
error-free
33. Title
The title should be short, but descriptive. It
should indicate the relationship or question
you investigated.
– Effect of time spent on homework on student
performance in Physics
– Better yet- give the result: Increased homework
effort results in increased student performance
34. Author(s) and address
• Student A. Student, Department of Stuff,
So-and-So Medical Center, Yourcity, ST
35. Introduction
Write one sentence describing the general
topic to be investigated and/or why it is
important or what remains to be done
– It has been previously noted that the amount of
study time devoted to a particular subject can
influence student performance. However, the
relationship between student effort and
performance has not been systematically
investigated.
36. What you did
Write one or two sentences describing the
specific question you are addressing or
relationship you are investigating with this
investigation
– In the work reported here, we examined the
effect of time engaged in homework on overall
student performance (can continue sentence…
by…)
37. Method
Write one or two sentences describing how
you did the investigation. Do not attempt to
write a detailed procedure; instead, just give
a general idea of methods.
– Students self-reported the number of minutes
spent doing homework for physics each night
for four weeks. This number was averaged and
plotted against the average grade of the student
for all tests and quizzes during the same period.
38. Results
• Write one or two sentences explaining what
you found out. Be as specific as possible,
but state only your main point(s). Use the
past tense.
– We found a positive relationship between the
average number of hours/week spent doing
homework and the average grade for each
student. The correlation coefficient for the
entire class was 0.933.
39. Conclusion
• Summary of everything you found, in different
words
• What are the implications of the research?
• Usually do NOT say what remains to be done
(unlike a paper)
– Students can increase their performance in school by
increasing the amount of time they spend engaged in
homework. These findings are especially important for
those low-performing students who are on the verge of
flunking.
40. Tissue distribution and processing of proSAAS by proprotein convertases. M.
Sayah, Y. Fortenberry, A. Cameron, and I. Lindberg, Department of Biochemistry and
Molecular Biology, LSU Health Sciences Center, New Orleans, LA
The conversion of inactive precursor proteins into bioactive neuropeptides and peptide
hormones involves the proteolytic enzymes prohormone convertases PC1 and PC2. The
neuroendocrine protein 7B2 represents a specific binding protein for PC2, and the protein
proSAAS, which interacts with PC1, exhibits certain structural and functional homologies
with 7B2. With the intention of better understanding the physiological role of proSAAS and
its derived peptides, we investigated its tissue localization using a new radioimmunoassay
(RIA) to a carboxyl terminal proSAAS-derived peptide. Immunoreactivity corresponding to
this SAAS-derived peptide was mostly localized to the brain and the gut. Analysis of the
brain distribution of the proSAAS-derived peptides indicates that the hypothalamus and the
pituitary are the two richest areas, consistent with the previously described high expression
of PC1 in these two areas. In order to investigate the cleavages of proSAAS by
prohormone convertases, we incubated recombinant His-tagged proSAAS with
recombinant mouse proPC2 or furin, separated the cleavage products by HPGPC and
analyzed the products by RIA. Our results indicate that either PC2 or furin can accomplish
in vitro rapid removal and efficient internal processing of the carboxyl terminal peptide (CT
peptide), exposing the inhibitory hexapeptide to possible further digestion by
carboxypeptidases. Finally, we also studied proSAAS processing in the brains of wild type
and PC2 null mice and found that proSAAS is efficiently processed in vivo. Whereas the
CT peptide is mostly internally cleaved in wild type mouse brain, it is not processed as
efficiently in the brains of PC2 null mice, suggesting that PC2 is partially responsible for
this cleavage in vivo. These data support a complex interrelationship between the two
convertases and their inhibitors.
41. Embryonic Stem Cell-Derived Cardiomyocytes: Establishment of a Model System for
Studying Differentiation of Cardiac Pacemaking Myocytes. Steven M. White. Department of
Biochemistry and Molecular Biology, LSUHSC, New Orleans, LA 70112.
Embryonic stem (ES) cell-derived cardiomyocytes provide unique models for studying cardiac
development and differentiation in vitro. Our goal is to use genetic selection as a means to isolate
a pure population of cardiac myocytes that function as specialized pacemaking or conducting cells
from differentiating, genetically-altered murine ES cells. By using a cell-specific promoter
controlling expression of a drug-resistance gene and later applying that drug, we are able to
select a pure population of the cells of interest. By including the promoter/enhancer region of the
cardiac-specific a-myosin heavy chain (a -MHC) gene in a selection vector, we have isolated
pure populations of cardiomyocytes.
Endothelial-derived paracrine signaling molecules have been shown to induce
cardiomyocytes to differentiate into conducting cells. Preliminary results using the HL-1
cardiomyocyte line indicate that treatment of HL-1 cells with the endothelial-derived factors
endothelin-1 and neuregulin-1 induces expression of genes characteristic of conducting
cardiomyocytes. By following the expression of a genetic marker for the murine cardiac
conduction system, the potassium channel b subunit minK, we are currently attempting to isolate
conducting cardiomyocytes. Preliminary studies examining the developmental expression of
minK in differentiating ES cell aggregates (called embryoid bodies) using lacZ under control of the
endogenous minK promoter, show that minK expression begins between days 7 and 8 of
development within discrete regions of the embryoid bodies. The ability to isolate pure
populations of conducting cardiomyocytes will permit the development of model systems to study
cardiomyocyte differentiation, which should lead to new pharmaceutical agents and cellular
therapies to treat heart disease.
