CoMPARA: Collaborative Modeling Project for Androgen Receptor ActivityKamel Mansouri
In order to protect human health from chemicals that can mimic natural hormones, the U. S. Congress mandated the U.S. EPA to screen chemicals for their potential to be endocrine disruptors through the Endocrine Disruptor Screening Program (EDSP). However, the number of chemicals to which humans are exposed is too large (tens of thousands) to be accommodated by the EDSP Tier 1 battery, so combinations of in vitro high-throughput screening (HTS) assays and computational models are being developed to help prioritize chemicals for more detailed testing. Previously, CERAPP (Collaborative Estrogen Receptor Activity Prediction Project) demonstrated the effectiveness of combining many QSAR models trained on HTS data to prioritize a large chemical list for estrogen receptor activity. The limitations of single models were overcome by combining all models built by the consortium into consensus predictions. CoMPARA is a larger scale collaboration between 35 international groups, following the steps of CERAPP to model androgen receptor activity using a common training set of 1746 compounds provided by U.S. EPA. Eleven HTS ToxCast/Tox21 in vitro assays were integrated into a computational network model to detect true AR activity. Bootstrap uncertainty quantification was used to remove potential false positives/negatives. Reference chemicals (158) from the literature were used to validate the model, which showed 95.2% and 97.5% balanced accuracies for AR agonists and antagonists respectively. A library of ~80k chemical structure, including ~11k chemicals curated from PubChem literature data using ScrubChem tools was integrated with CoMPARA’s consensus predictions that combined several structure-based and QSAR modeling approaches. The results of this project will be used to prioritize a large set of more than 50k chemicals for further testing over the next phases of ToxCast/Tox21, among other projects. This work does not reflect the official policy of any federal agency.

Major Project (B. Pharm) OPIUM POPPY PROJECT.pdfRAHUL PAL
Opium cultivation, an ancient practice rooted in regions like the Golden Triangle and Golden Crescent, involves a meticulous process blending nature and human intervention. Picture a serene landscape with gently rolling hills blanketed in lush greenery. Amidst this verdant tapestry stand tall, slender opium poppy plants, their delicate petals shimmering in hues of pink and white. These plants exude an air of mystique, their bulbous seed pods containing the coveted opium latex. Skilled farmers nurture these plants with utmost care, tending to their needs for water, nutrients, and protection from pests. The cultivation cycle begins with sowing the poppy seeds during specific seasons conducive to their growth. As the plants mature, they blossom into exquisite flowers, each harboring the potential for opium production. The farmers deftly slit the seed pods at just the right moment, allowing the milky sap to seep out and gradually solidify into opium. This labor-intensive process demands precision and patience, as any misstep can impact the potency and quality of the opium yield. Despite its allure, opium cultivation is not without controversy and challenges. Legal restrictions, environmental concerns, and the socioeconomic impacts on communities underscore the complex nature of this age-old practice. However, for those entrenched in the art of opium cultivation, it remains a delicate dance between tradition, livelihood, and the ever-evolving dynamics of global demand and supply.
Niosomes are nanosized vesicles composed of nonionic surfactants and cholesterol that form when these compounds are dispersed in an aqueous medium. These lipid-based structures are similar to liposomes but differ in their composition, as niosomes use nonionic surfactants instead of phospholipids. The unique characteristic of niosomes lies in their ability to encapsulate both hydrophilic and hydrophobic drugs within their bilayer membrane. This feature makes them promising candidates for drug delivery systems, as they can protect the encapsulated drug from degradation, prolong its release, and enhance its bioavailability. Additionally, niosomes offer advantages such as biocompatibility, stability, and ease of preparation, making them a versatile platform for targeted drug delivery and other biomedical applications.
Niosome An Non-Ionic Surfactant Vesicles.pptxRAHUL PAL
Niosomes are novel drug delivery systems that have garnered significant interest in the pharmaceutical field.

Targeted drug delivery systems are employed to administer pharmaceutical medication,
facilitating the precise delivery of drugs to specific diseased areas. Several drug delivery
systems utilise carriers such as antibodies, transdermal patches, biodegradable polymers,
nanoparticles (NPs), liposomes, niosomes, and microspheres. Niosomes, on the other hand,
represent a promising and innovative category of vesicular systems. Niosomes are vesicles
formed by hydrating a combination of nonionic surfactants and cholesterol. These non-ionic
surfactant vesicles serve as carriers for both amphiphilic and lipophilic drugs. In the drug
delivery system using niosomes, the medication is enclosed within a vesicle. Niosomes in
tuberculosis (TB) possess biodegradable and biocompatible properties, are non-immunogenic,
and demonstrate versatility in their structural composition. It’s a serious and potentially deadly
infectious disease caused by a bacteria called Mycobacterium tuberculosis. In the recent
update, WHO still estimates 9.9 million new TB cases in 2022 at the latest. Involvement of
niosomes improves the treatment of TB with much more advanced technology and an advanced
drug nanocarrier with better treatment. The main highlights of this review paper are to
summarise the structure, compositions, preparation methods, and ICH stability guidelines for
the formulation of niosomes and their applications in TB with their several stages of treatment

Determination of Partition coefficient of Known and Unknown drug.pdfRAHUL PAL
Partition coefficient, often denoted as P or P_oct, is a measure of how a solute distributes between two immiscible (unmixable) solvents. It is commonly used in chemistry, biochemistry, and pharmacology to understand the distribution of a compound between different phases, such as between a hydrophobic organic solvent and water. In experimental settings, the partition coefficient is determined by measuring the concentrations of the solute in each phase. The values obtained provide insights into the solute's behavior and can guide decisions in various scientific and industrial processes.
A pharmaceutical suspension is a heterogeneous system in which finely divided solid particles are dispersed in a liquid medium. Unlike solutions, where solutes are completely dissolved, suspensions involve particles that are only partially soluble or insoluble in the liquid. These suspensions are commonly used in the pharmaceutical industry to deliver medications that may be poorly soluble or unstable in their pure form. The solid particles, often in the form of powders or crystals, are dispersed throughout the liquid phase, creating a stable mixture through the use of suspending agents or stabilizers. These agents prevent the settling of particles, ensuring uniform distribution and ease of redispersion upon shaking before administration. Pharmaceutical suspensions offer advantages in terms of flexibility in dosing and formulation, enabling the delivery of therapeutic agents in various forms such as oral liquids, injectables, or topical preparations, enhancing patient compliance and therapeutic efficacy. The formulation and stability of pharmaceutical suspensions require careful consideration of factors such as particle size, density, and the choice of stabilizers to maintain a consistent and reliable product.

Composition: They are solid, bullet-shaped or cone-shaped dosage forms that contain medication in a base that melts or dissolves at body temperature.
Rectal Suppositories: Commonly used for medications that need to bypass the digestive system or when a patient cannot take medications orally. They are inserted into the rectum.
Vaginal Suppositories: Often used for localized treatment of gynecological conditions, such as yeast infections or hormonal therapy. They are inserted into the vagina.
Pessaries:
Usage: Pessaries are specifically designed for vaginal administration.
Composition: They are solid, oval-shaped or ring-shaped devices made of various materials such as silicone, rubber, or plastic.
Indications: Pessaries are mainly used to support the uterus, bladder, or rectum in cases of pelvic organ prolapse. However, they can also be used for the controlled release of medication into the vagina for the treatment of local conditions.
Maintenance: Pessaries need to be fitted by a healthcare professional and should be cleaned and reinserted regularly.
Partition Coefficient Determination (Pharmaceutics Practical).pptxRAHUL PAL
Partition coefficients are a fascinating and important concept in many fields, from chemistry and environmental science to medicine and pharmacology. They tell us about how a substance will distribute itself between two immiscible phases, like how a drug might move between your blood and tissues, or how a pollutant might spread through soil and water.
A partition coefficient, denoted as P or log P, describes the ratio of the concentration of a compound in one phase (usually organic) to its concentration in another phase (often water) at equilibrium.
Higher values of P indicate a greater preference for the organic phase, meaning the compound is more lipophilic (fat-loving).
Lower values of P suggest a higher affinity for the aqueous phase, implying the compound is more hydrophilic (water-loving).

Ethical guidelines and regulations also play a significant role in addressing and preventing these conflicts in medical research.
Research Article Published: "Optimization and formulation of dox loaded lipos...RAHUL PAL
Doxorubicin (DOX) is a potent anticancer drug, but it is also associated with significant side effects, such as cardiotoxicity. Liposomal encapsulation of DOX can help to reduce these side effects and improve the drug's efficacy.
There are a number of different factors that can affect the optimization and formulation of DOX-loaded liposomes, including:
Lipid composition: The type and ratio of lipids used to form the liposomes can affect their size, stability, and drug encapsulation efficiency. Some commonly used lipids for DOX liposomes include hydrogenated soy phosphatidylcholine (HSPC), cholesterol, and distearoylphosphatidylglycerol (DSPG).
Drug loading method: There are a number of different methods for loading DOX into liposomes. Some common methods include the ammonium sulfate gradient method, the remote loading method, and the ethanol injection method. The choice of loading method can affect the drug encapsulation efficiency and stability of the liposomes.
Liposome size: The size of the liposomes can affect their circulation time in the body and their ability to target specific tissues. Smaller liposomes tend to have a longer circulation time and are better able to penetrate tumors.
Surface modification: Liposomes can be surface-modified with various ligands to improve their targeting and delivery properties. For example, liposomes can be conjugated with antibodies to target specific cancer cells.
The optimization of DOX-loaded liposomes is typically carried out using a quality by design (QbD) approach. QbD is a systematic approach to drug development that focuses on identifying and controlling the critical quality attributes (CQAs) of the drug product. The CQAs of DOX-loaded liposomes may include particle size, drug encapsulation efficiency, stability, and in vitro and in vivo performance.

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.

02) Selecting the appropriate pk/pd model: The type of pk/pd selected depends on the drug and the data
have. Some common model as follows:
- One compartment Model
- Two compartment Model
- Michaelis-Menten Model
- Emax. Model.
03) Fitting the model to data: WinNonlin uses variety of methods to fit the models to data, including
least squares methods & the maximum likelihood methods.
04) Evaluating the model fit: When fit the model to data, need to evaluate the model fit. This done by
locking at the residual plots and the R-squared values.
05) Calculating the pk/pd parameter: When evaluation had done of model fit, then calculate the pk/pd
parameters. These parameters tell the drug how much absorbed, distribute, metabolized and
eliminated.
06) Generating the reports: WinNonlin can generate a variety of reports in tables, graphs 7 figure. These
reports can use to communicate the result of analysis to others.
EXPERIMENTAL PROCEDURE: The procedure to determine the PK/PD in the software as following:
01. Import the Data: Open WinNonlin, click on the “file” menu & select the “import Data”.
- Select the “table” option & click on the “next button”.
- Select the CSV file that contains your data & click on the
“open” button.
- The data will be imported into the WinNonlin in a table.

02. Selecting the appropriate pk/pd model:
One compartment model: ADME of drug are rapidly absorbed & distributed throughout the body.
Two compartment model: ADME of drug are slowly absorbed & distributed throughout the body.
Michaelis Menten Model: The Relation between the drug conc. & response. It describes the rate of
enzymatic reaction.
Emax. Model: Similar to the Michaelis equation, describes the max. response that drug achieved.
Drug Type Appropriate pk/Pd Model Example
Rapidly
absorption/distribution
One compartmental model Aminoglycosides. Warfarin,
propranolol, insulin
Slowly
absorption/distribution
Two compartmental model Digoxin, phenytoin, theophylline
Drug with a clear dose
response relationship
Michaelis Menten equation Warfarin, penicillin,
acetylcholinesterase
Drug with an all-or-
none response
Emax. Aspirin, chlorpheniramine,
epinephrine and nifedipine
03. Fitting the Appropriate Model to data: Here some of the steps as follows:
a) Open WinNonlin software & create the new project: Go to “File”>New>Project. In the project
dialog box, select the modeling project type & click Ok.
b) Import the plasma conc. & time data into WinNonlin Software: Go to “File > Import. In the
import dialog box, select the one compartment model type & click Ok.
c) Create the One compartment model in WinNonlin Software: Go to Model > New Model. In
the new model dialog box., select the one compartment model & click Ok.
d) Fill the model to the using data the Non-Linear Regression tools in WinNonlin Software: Go
to model>, in the fit dialog bx, select the non-linear regression tab. In the model field, select the
one compartment model that, created in step. 3. In the data field, select the plasma conc. data that
you imported in step. 2, click Ok.
e) Evaluate the fit of model to data: Go to “View> Fit result, Fit the results the dialog box will
show you the result of non-linear regression fit. Evaluate the fit of model to data.

f) Save the model & result.
04. Evaluating the Model Fit:
- Residual plots: Good randomly scattered around the line of zero.
- R- Squared Value: A high R2
Value (closer to 1) indicate- Good Fit.
- Low R2 Value (closer to 0) indicate – Poor fit.
- AIC/BIC: Lowest AIC/BIC mean best fit.
- Visual Inspection: Smooth Curve.
05. Calculating the PK/PD parameters:
- Cl = Dose/AUC
- Vd= AUC/Cmax. – AUC calculate by the go to.
- T1/2 = 1H (2)/Cl – “View> Area Under Curve”. The area under curve dialog box show
AUC for the fitted model.
06. Generating Reports: The reports generate d of Pk reports includes ADME of drug.
- PD reports for relationship between the drug plasma conc. & effect on blood
pressure.
- Safety reports.
Result: The PK/PD of given beta-blocker propranolol drug has been calculated & graph will plot carefully.
