A UX Journey into the World of Early Drug DiscoveryJennifer Cham
Developing new medicines is an extremely challenging process with more than 50% of new medicines failing in late-stage development where the cost is the greatest. One of the main reasons for attrition is insufficient knowledge about the nature of the gene or protein (target) involved in a disease. Scientists in pharmaceutical research and development use diverse data and software applications to aid decision-making for drug target identification and validation.
We have been designing a new web portal to support researchers working within the pharmaceutical industry and academic organisations with the aim to make early drug target identification more efficient.
We will report on how we applied a range of participatory design methods including interviews, observations, sketching workshops, paper prototyping and usability testing to understand how experts carry out the very early stages of drug discovery. We will discuss the challenges of working in this domain and the extent to which standard UX approaches helped us understand what matters for our potential users so we could design and deliver solutions within an Agile framework. We also mention when popular UX methods didn't work in this complex environment and how we addressed these issues.
This work has been carried out via the Centre for Therapeutic Target Validation, a partnership between the European Bioinformatics Institute, the Wellcome Trust Sanger Institute and GlaxoSmithKline. See www.targetvalidation.org
Well-trained clinical research professionals are in high demand. The tremendous increase in medical technology and information in the last decade has resulted in an explosion of potential new drugs, devices and biologics that must be tested before being released for use by the public. The profession is constantly challenged to improve and streamline the clinical research programs in order to shorten the development timelines and control the cost for new product development

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.
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.

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

25. 3.Animal PK/PD-Lead Optimization
Animal pharmacokinetics (ADME) and
pharmacodynamics (PD) assess the general
pharmacology and mechanisms of action of
drugs..
Lead molecules are administered via different
routes: intravenous (iv), intraperitoneal (ip),
subcutaneous (sc), intramuscular (im), rectal,
intranasal (IN), inhalational, oral , trans
dermal, topical, etc
The main models used are rodents including
mouse and rat, but larger animals such as
dogs, pigs, and, more rarely, monkeys, are also
used under certain circumstances.
26. 3.Animal PK/PD-Parameters
• PK/PD studies rely heavily on analytical methods and
instrumentation. The recent innovation and progress in
mass spectroscopy, (whole-body) imaging, and
chromatography technology (HPLC, LC-MS, GC-MS) have
tremendously increased the quantity and quality of data
generated in PK/PD experiments.
A large number of parameters is assessed. Here is a
partial list:
(ADME); bioavailability (F) and protein binding; stability
and half-life (t1/2); maximum serum concentration
(Cmax); total exposure or area under the curve (AUC);
clearance (Cl); volume of distribution (Vd); drug drug
interactions; onset of drug action; multicompartmental
analysis of blood, liver, and other tissues.
28. 4.Toxicity-Lead Optimization
The toxicity is the degree to which a substance or mixture of substances can
harm human or animals.
Acute Toxicity
Acute toxicity involves harmful
effects in an organism through
a single or short-term
exposure.
Chronic Toxicity
Chronic toxicity is the ability of
a substance or mixture of
substances to cause harmful
effects over an extended
period.
32. Pre-Clinical Studies
Once the drug is designed it have to be tested

Secondary: To determine the minimum number of individual doses into which that maximum tolerated sub-chronic daily dose of drug must be divided, and to test whether the dose and schedule so determined can also be tolerated during a treatment period of seven days
Phase 2 studies are done in diseased individual to evaluate the safety and efficacy of the drug
It is also called as therapeutic exploratory studies
Done in a population size of 100-300
Phase 2 studies are of 2 types phase 2 A and Phase 2 B
The objective of phase 2A Studies is to evaluate dosing requirement
Phase 2B is to evaluate efficacy
Phase 3
Done in a large population- above 300
Evaluation of efficacy and safety profile (initial risk benefit assessment)
Identification of the disease sub types for which drug is effective.
Comparison with other standard drugs.
Pharmacokinetics with others drugs and Quality of life (depends) are evaluated.
Done in a large group of people around 300-3000
Done in a diseased individuals
Phase 3 trials are randomized controlled trial
It is also called as multicentre trial
It is a therapeutic confirmatory study
Clinical Trials are expanded controlled
and uncontrolled trials. They are carried
out on 500 to 3,000 patients in situations similar
to those of actual clinical practice—in clinics, outpatient
hospital facilities, and private practice.
These studies are performed after a drug’s efficacy
has been established, at least to some degree, and
are intended to gather additional evidence of drug
effectiveness, to discover rarer drug effects or effects
that develop after longer periods, and to better
define the frequency and severity of more common
effects as well as the proper use of the drug
Once the phase 3 trial shows greater benefits then risk the NDA application is filed with regulatory .NDA constitutes of administrative as well as data from the clinical trial. The review and approval process takes around 2-3 years
After the NDA is filed, a team of FDA reviewers
analyzes the sponsor’s summaries of the data
or, when needed, the actual data. The review team
includes a physician, who reviews the clinical test
results; a pharmacologist, who reviews the animal
test results; and a chemist, who reviews the chemical
data and manufacturing controls and processes;
supported by a biopharmaceutical specialist,
a biometrician, and, when applicable, a microbiologist.
The main objective of the process is to
ensure that the data from the clinical experiments
support the claims for the drug’s safety and efficacy
in the labeling the sponsor submitted.
NDAs may be presented for consideration to
advisory committees composed of experts (mostly
nongovernmental) in the various subspecialties of
medicine, in clinical pharmacology, and in biometrics.
The committees recommend whether or
not an NDA should be approved to market a drug
and, if the drug is approved, what wording should
appear in its labeling. They also may recommend
whether the sponsor should be requested to carry
out additional studies after the drug is marketed.
If the committees recommend against approval,
they identify deficiencies and may suggest new
studies that need to be done by the sponsor to further
investigate the drug’s safety and efficacy.
