Pharmacogenomics
- Pharmacogenomics deals with how genetic variations influence individual responses to drugs in terms of efficacy and toxicity. It aims to identify individuals who are more or less likely to respond to drugs or require altered doses.
- Pharmacogenetics studies variations in targeted genes or related genes, while pharmacogenomics uses genetic information to guide individualized drug and dose choice.
- Genetic polymorphisms like SNPs can result in different amino acids, protein changes, or no effect. They influence drug metabolism and response.
- Pharmacogenomics offers advantages like personalized medicine but faces barriers like complexity, education needs, and drug company incentives. It is being applied in various stages of clinical trials from target identification to dosing.
Pharmacogenomics
Pharmacogenomics examines genetic variations that influence individual drug responses. Single nucleotide polymorphisms (SNPs) can predict good, bad, or no response to a drug. DNA microarrays efficiently identify SNPs to personalize treatment. This allows excluding non-responsive patients from trials, improving drug safety and efficacy. Currently, pharmacogenomics guides cancer treatment and medications metabolized by cytochrome P450 enzymes to prevent overdosing. Benefits include tailored therapy and safer drugs, though complexity challenges wide implementation.
Pharmacogenomics & its ethical issues
Humans are 99% similar to each other; but it is the 1% that is the cause of concern. This relatively small difference actually how a drug will effect our body. Pharmacogenomics is the study of how genes affect a person’s response to drugs. In order to prevent any unwanted reactions it has become necessary to consider one's genome while prescribing medicine. Thus pharmacogenomics is the starting point of personalized medicine.

It provides examples of how factors like age, gender, pregnancy, disease states, genetics, route of administration, and food can impact drug absorption, distribution, metabolism, and excretion. It also covers concepts like tolerance, tachyphylaxis, teratogenicity, and drug-drug interactions that can alter a drug's effects.
Introduction to Pharmacology.pptx pptttt
Pharmacology is the study of drugs, including what they do in the body, how they act, their uses and adverse effects. Throughout history, people have used plants and other substances to treat illnesses, and modern pharmacology developed through experimentation and clinical trials. Pharmacology involves understanding how drugs are absorbed, distributed, and eliminated from the body as well as their effects, mechanisms of action, and interactions with receptors and other proteins in the body.
[Final] Pharmacogenetics and Pharmacogenomics - WITH NOTES
This document summarizes a seminar presentation on the role of pharmacogenetics and pharmacogenomics in drug development and regulatory review. It discusses how genetic differences can impact how individuals metabolize and respond to drugs in terms of pharmacokinetics and pharmacodynamics. Factors like ethnicity, age, organ function, and genetics were presented as influencing a drug's effects. The role of metabolizing enzymes and transporters encoded by polymorphic genes in contributing to variability in drug responses and adverse events was emphasized. The importance of considering such genetic data during clinical trials and including relevant information in drug labels to allow for personalized dosing was also stressed.
1. Pharmacogenomics.pptx
Pharmacogenomics leads to more personalized drug therapy by understanding how an individual's genetics affects their response to medications. Variations in genes can impact drug receptors, metabolism, and other factors. Understanding these genetic differences could allow doctors to prescribe safer and more effective medications at the right dose for each patient.

ALL CHAPTERS OF PHARMACOLOGY.pptx
This document provides an overview of key concepts in pharmacology. It begins with definitions of pharmacology and drugs. It then discusses sources of drugs, routes of drug administration, pharmacokinetics including absorption, distribution, metabolism and excretion. Pharmacodynamics including mechanisms of drug action and receptor interactions are also covered. Principles of drug action such as stimulation, depression, irritation and replacement are defined. The document concludes with sections on half-life, onset/peak/duration, and concepts of synergism and antagonism when multiple drugs are administered.
Introduction to pharmacokinetics and pharmacodynamics 2022.doc
Studying pharmacology provides an understanding of drug interactions with living systems and their optimal medical use. Pharmacology deals with drugs obtained from natural, synthetic, and biotechnology sources. Drugs vary in properties like size, chemistry, and stereochemistry. They are named chemically, generically, and by proprietary names. Good drugs are selected based on effectiveness, safety, and other factors. A drug's clinical response depends on pharmacokinetic and pharmacodynamic variables. Adverse drug reactions can occur and are studied in toxicology. New drugs undergo extensive testing and regulatory approval processes. Pharmacodynamics concerns drug mechanisms of action through receptor interactions and relationships between drug concentrations and responses.
factors modifyng drug effcts
This document discusses factors that can cause variability in individual responses to drugs. It identifies two types of factors - quantitative factors that increase or decrease drug levels, and qualitative factors that alter the type of response. Some key factors discussed include body weight, age, sex, genetics, disease states, and environmental influences. Tolerance, drug interactions, and cumulative effects can also impact drug responses. Adjusting drug dosages based on these factors can help optimize treatment for each individual.

The book explores the immune system from its basic roles and evolution to cutting edge areas like immunotherapy and vaccine development. It aims to convey both the complexity of immunology and its tremendous impact on human health.
Algal-Biotechnology-and-its-Scope.pptx
Algal biotechnology uses microalgae in applications like food supplements, wastewater treatment, and biofuels. It provides sustainable resources as an alternative to petroleum. Benefits include reduced emissions, improved water quality, and new jobs. Applications include biofuel production, pharmaceuticals, and wastewater treatment. Challenges involve sustainability, costs, and regulations. Future prospects lie in genetic engineering, new algae species, biofuels, agriculture, and industry partnerships.
Microbial-Taxonomy-and-Tools.pptx
Microbial taxonomy is the classification and naming of microorganisms. It provides a systematic framework to categorize the incredible diversity of microscopic life. Traditional taxonomy methods used morphological and biochemical characteristics as well as genetic markers like DNA sequences to differentiate microorganisms. Modern tools like high-throughput sequencing and bioinformatics have revolutionized taxonomy by allowing analysis of microbial diversity at large scales. Microbial taxonomy contributes to understanding infectious diseases and developing therapies as well as assessing ecosystem health and enabling biotechnological advancements. Emerging trends like metagenomics and technological advances will continue shaping the future of microbial classification.
VECTORS.pptx
Vectors are molecules that can deliver foreign DNA into host cells. Common vectors include plasmids, bacteriophages, cosmids, BACs, and YACs. Vectors must be able to replicate autonomously in host cells and contain selectable markers like antibiotic resistance genes. Key vector features include an origin of replication for autonomous replication, cloning sites for inserting foreign DNA, and markers for identifying recombinant cells. Different vector types have varying maximum insert sizes, ranging from a few kilobases for plasmids to hundreds of kilobases for YACs. Vectors allow genetic material to be artificially introduced, expressed, and studied in host cells and organisms.
BASIC DNA REPAIR MECHANISMS.pptx
This document discusses several DNA repair mechanisms including photoreactivation, direct repair mechanisms like base excision repair and nucleotide excision repair, mismatch repair, recombination repair, and SOS repair. It provides details on how each repair mechanism works to identify and repair different types of DNA damage like thymine dimers, mismatches, gaps, and damage caused by environmental stress.
Gene regulation
Gene regulation ensures that the appropriate genes are expressed at the proper times and helps organisms respond to their environment. It involves mechanisms that increase or decrease production of gene products. The lac operon in E. coli regulates lactose metabolism genes in response to lactose and glucose levels. When lactose is present, it induces the operon by binding the repressor protein and allowing transcription. When glucose is high, cAMP levels are low and transcription is low. The lac operon precisely controls lactose gene expression through a repressor protein and RNA polymerase binding.
Antigen antibody reactions
Antigen-antibody reactions involve the binding between antigens and antibodies. This document discusses the properties, mechanisms, and types of antigen-antibody reactions. It describes how antigen-antibody complexes form through primary, secondary, and tertiary stages. Precipitation reactions are commonly used serological tests that form visible precipitates when antigens and antibodies bind. Immunodiffusion techniques like single and double diffusion tests in agar gels are also summarized.
Screening of industrial microorganisms
This document discusses screening techniques used to isolate microorganisms of interest from a population. It describes primary screening as an initial process to discard many non-useful microbes while detecting a small percentage that may have industrial applications. Secondary screening further tests the capabilities of these isolated microorganisms to determine their real potential value. Some primary screening techniques mentioned include using crowded plates, detecting organic acid production, and screening for antibiotic production. The document also discusses improving crowded plate techniques and the goals and approaches of secondary screening to evaluate a microorganism's potential for industrial use.
Vitamin
Vitamins are essential nutrients that our bodies cannot produce on their own. Many vitamins are produced through fermentation, a process where microorganisms break down or convert carbohydrates into acids, gases and/or alcohol. Common vitamins produced this way include vitamin B12, riboflavin, niacin, biotin and pantothenic acid.
Fermentation of wine
The fermentation process is essential for transforming grape juice into wine. Yeast is added to grape juice which feeds on the natural sugars and converts them to alcohol and carbon dioxide over several weeks. Through this process, the alcohol content increases while the sweetness of the grape juice decreases, creating the final wine product.
Yeasts
Yeasts have various applications in brewing and food production. Brewers yeast is used to produce beer through the fermentation of sugars into alcohol and carbon dioxide. Food yeast is used in baking to produce leavened bread and other baked goods through a similar fermentation process where yeast converts sugars into carbon dioxide gas which causes dough to rise.
Enzyme production
Enzymes are proteins that act as catalysts in biochemical reactions and are essential for life. Many industries produce enzymes at large scales for use in food processing, cleaning products, and other applications. Advances in biotechnology have enabled the production of enzymes through fermentation using genetically engineered microorganisms for high yields.
Biosynthesis of purine and pyrimidine
Purines and pyrimidines are organic nitrogenous bases that are essential components of nucleic acids like DNA and RNA. They are synthesized through complex metabolic pathways involving multiple enzymes and organic precursors within living cells. Disruptions to purine and pyrimidine biosynthesis can lead to various genetic disorders and diseases if not properly regulated.
Mutation
Mutations are changes to an organism's DNA sequence that can occur during cell division or DNA replication. These changes may include substitutions, insertions or deletions of genetic material. Mutations can be caused by errors during DNA replication or by exposure to mutagens like radiation or chemicals.
Genetic code
The genetic code is the set of rules by which information encoded in genetic material (DNA or mRNA sequences) is translated into proteins by living cells. The genetic code is highly similar across all Earth life forms and specifies how sequences of nucleotide bases in nucleic acids (DNA or RNA) correspond to amino acid sequences in proteins. The genetic code consists of three-letter "words" called codons formed from a sequence of three nucleotides, with some redundancy that allows some codons to specify the same amino acid.
Mapping of genome
Scientists have mapped the entire human genome, determining the precise sequence of DNA base pairs that make up human genes and chromosomes. This landmark achievement provides valuable insights into human evolution and holds promise for advances in medicine, as it allows researchers to pinpoint genetic variations that influence health and disease. The genome project is considered one of the great scientific accomplishments of all time and represents an important step toward understanding our genetic blueprint.
Genetic recombination
Genetic recombination is the process by which genetic material is exchanged between two organisms or between different parts of the same organism. It involves the breaking and rejoining of DNA strands. Recombination allows for new combinations of genes to arise, increasing genetic diversity in a population.
Fermentation of ABE and butanediol
Fermentation of ABE produces acetone, butanol and ethanol through fermentation. Fermentation of 2,3 butanediol has advantages and its production pathway involves converting pyruvate to 2,3 butanediol. Testing for 2,3 butanediol fermentation can be done using MR VP biochemical tests where MR VP positive organisms are able to produce 2,3 butanediol.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

- 2. WHY PHARMACOGENOMICS? • Medicine is personal: – We are all different. – Some of our differences translate into how we react to drugs as individuals. • This is personalized medicine. • The Goal of Personalized Medicine The Right Dose of The Right Drug for The Right Indication for The Right Patient at The Right Time.
- 3. SO, • Why does someone need twice the standard dose to be effective? • Why does this drug work for you but not me? • Why do I have side-effects and you don’t? • Why do some people get cancer and others don’t?
- 5. Pharmacogenetics: The role of genetics in drug responses. OR Study of individual gene-drug interactions, usually one or two genes that have dominant effect on a drug response.
- 6. Pharmacogenomics: The science that allows us to predict a response to drugs based on an individuals genetic makeup. OR Study of genomic influence on drug response, often using high-throughput data (sequencing, SNP chip, expression, proteomics- COMPLEX interactions).
- 7. WHAT IS PHARMACOGENOMICS? • Study of the role of genetics in drug response and • The influence of genetic variation on drug response in patients. • Correlate gene expression or single-nucleotide polymorphisms with drug absorption, distribution, metabolism and elimination. • As well as drug receptor target effects
- 8. • Aims to optimize drug therapy, with respect to the patients' genotype • Ensure maximum efficacy with minimal adverse effects. • Drugs are optimized for each individual’s genetic makeup. • To provide pharmacogenomic based recommendations for a given drug, two possible types of input can be used: – genotyping or exome or – whole genome sequencing.
- 9. It’s all about what makes YOUR genetic code UNIQUE!
- 10. Genetic Code: DNA DeoxyriboNucleic Acid (DNA) contains all the information necessary to make a complete. organism DNA is composed of a combination of 4 nucleotides A T C G Adenine Thymine Cytosine Guanine
- 11. DNA: A long double-stranded string of nucleotides that encode for many genes. Gene Protein: Proteins are composed amino acids. Amino acids are made from triplets of nucleotides called codons. Amino acid 1 Amino acid 2 Protein! RNA: A single-stranded copy of one gene. The Central Dogma: DNARNAProtein Codon 1 Codon 2
- 12. A small change in the gene sequence can result in a very different protein ATG GTG CTG TCT CCT Met Leu Ser Pro DNA: Amino Acids/Protein: Val Words: Tom and Sam are bad ATG GTG CTG TCT ACT Met Leu Ser Thr DNA: Amino Acids/Protein: Val Tom and Sam are sadWords: Changes in DNA are called variations or mutations Variations in the DNA (genotype) can cause observable changes (phenotype) in individuals
- 13. Variations in our DNA make us UNIQUE!
- 14. What are the reasons a person would react differently to drugs? 1. Having the receptor (protein) to recognize the drug 2. Other physiological traits that enable you to respond to a drug 3. How your body processes the drugs after receiving it
- 15. Having the receptor (protein) to recognize the drug
- 16. Drugs and Receptors Cell Drug (Ligand) Receptor (Protein)
- 17. Your DNA and Drugs Variation in genes can cause variation in receptors Cell Cell Cell Cell Cell Too Many (hypersensitive) Too Few (hyposensitive) Mutated (insensitive)
- 18. Other physiological traits that enable you to respond to a drug
- 19. The presence of receptors influence how we react to drugs like Tumoricide or chemicals like PTC Tumoricide Works! Tumoricide Does Not Work Her2- Her2+
- 20. Where are the PTC receptors? They are on your taste buds! If a person has more taste buds, then he/she may be able to taste the PTC more strongly.
- 21. How your body processes the drugs after receiving it
- 22. Drugs Life: • Absorption • Distribuition • Metabolism • Excretion
- 23. • Scientists have names for the four basic stages of a medicine's life in the body: absorption, distribution, metabolism, and excretion or ADME. • Medicines can be absorbed into the body in many different ways. – oral (swallowing an aspirin tablet), – inhalation (like an asthma medications), – intramuscular (getting a flu shot in an arm muscle), – subcutaneous (injecting insulin just under the skin), – intravenous (receiving chemotherapy through a vein), or – transdermal (wearing a skin patch).
- 24. • After that the drug is absorbed into the blood stream it is distributed throughout the body to the targeted organ. • Then it is broken down, or metabolized. This usually occurs in the body’s chemical processing and detoxifying plant – The liver – where chemicals are cut apart, stuck together, or transformed, making the substance easier to get rid of or excreted. • There are many proteins involved in each of these processes. You can imagine if a person had a genetic variation in a gene that affects one of these proteins then there may be a roadblock in the ADME process and a drug might not work the way it was intended.
