This presentation discusses in vivo carcinogenicity studies, including their principles, methods, and procedures. Carcinogenicity studies involve administering test substances to experimental animals over their lifetimes to observe for evidence of cancer development. The presentation describes the study design, which involves exposing test animals to various doses of substances over their lifetime and monitoring for tumors. Key steps include selecting suitable animal models, administering the test substance via routes similar to human exposure, monitoring animals over their lifetimes, and performing detailed examinations to identify any potential cancers.
Toxicity is the science dealing with properties, action, toxicity, fatal dose detection or interpretation of result of toxicological analysis & treatment of poison.
Toxicity studies helps to avoid adverse effect and enhance the safety of drug.
This slide provides the information about toxicity screening on experimental animals.
Alternative methods to animals testing are the development and implementation of test method that avoid use of live animals or use of less animals in method.
The council directive on protection of animals used for experiments and scientific purpose in article 23
“The commission and member states should encourage
research into development and validation of alternative methods which could provide the same level of information as that obtained in experiment using animals but which involves less animal”.
Alternative methods able to do:
Reduce Refine Replace
collectively called as “The 3Rs Principle”.
Needs for alternative methods
Because in laboratory animals may be:
Poisoned.
Deprived of food water and sleep.
Applied with skin and eye irritants.
Subjected to psychological stress.
Deliberately infected with the infected disease.
This presentation provides a knowledge about Safety Pharmacology, It's aim & objectives, issues, consideration in selection and design of study and test study, duration of study, various studies involved in safety pharmacology, its guidelines, preclinical safety pharmacology. An assignment for the subject, Clinical Research and Pharmacovigilance, 1st year M.Pharm, 2nd semester.

Safety pharmacology is a branch of pharmacology with its aim to predict the potential clinical risk profile of new chemical entities (NCEs).
It has the ability to predict the potential off-target drug effects on major organ systems which are associated with exposure in the therapeutic range and above.
As an essential part of the spectrum of drug discovery and development, safety pharmacology studies are generally conducted to determine the relative drug effect on main organs, including respiratory system, central nervous system, and cardiovascular system.Safety pharmacology is an essential part of the drug development process that aims to identify and predict adverse effects prior to clinical trials.
SP studies are described in the international conference on harmonization (ICH) S7A and S7B Guidelines.
This presentation enlists all the studies which are required before submission of IND. It include IND introduction , time period of study ,flowchart showing preclinical studies...

Dermal Irritation and Dermal Toxicity Studies Dinesh Gangoda
Dermal irritation and Corrosion test guidelines 204.
Dermal irritation is the production of reversible damage of the skin following the application of a test chemical for up to 4 hours.
Corrosive reactions are typified by ulcers, bleeding, bloody scabs, and, by the end of observation at 14 days, by discolouration due to blanching of the skin, complete areas of alopecia, and scars. Histopathology should be considered to evaluate questionable lesions. [1]
Dermal corrosion is the production of irreversible damage of the skin; namely, visible necrosis through the epidermis and into the dermis, following the application of a test chemical for up to four hours.[2]

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
