Part1
  • Bio-ethical Issues

4
Genetics and ethics
  • The release of individual genomic sequences could
    raise a number of ethical issues such as
  • Maintaining the confidentiality of genetic code
  • Insurance of individuals may be difficult
  • Employment avenues could get bleak
  • Selecting a life partner could be cumbersome

5
Problems with introduction of new technologies
  • Patenting
  • Intellectual property rights
  • Human psychology

6
To do or not to do??
  • One nucleotide mistake in the 8000 pairs in a
    gene can cause cancer such as BRCA1
  • Pre-plantation genetic diagnosis (PGD) is a
    technique wherein the genetic disease acquired
    from either parent could be detected much before
    the embryonic development takes place in the
    mothers womb
  • Whether to permit such diagnosis in future or not
    remains a big question as this could lead to
    production of test tube babies and clones in mass
    scale

7
People are divided on many issues
  • Right to screen the embryo genetically?
  • Genetics should be only for medical purposes?
  • When fertilization is done on petri dish through
    IVF then why not cloning?
  • Should stem cell research that provides lot of
    relief to patients (but can be catalytic for
    artificial organ development) be banned?

8
Designer babies and architect parents
  • Does the concept of designer babies seems
    logical?
  • This could lead to designer babies and instantly
    parents would become architects
  • Producing kids would become a commercial activity
    having more of engineered processes
  • Presently, people strongly disagree to this
  • Should we design children just as we
    design/customize cars and houses?
  • Shouldnt we leave to God to decide for Himself??

9
Cloning
  • The process of putting nucleus taken from any
    cell of body into an embryonic/egg cell
  • This is followed by a charged shock that joins
    the two (nucleus containing the genetic material
    and the nucleus in the egg)
  • Thereafter, cells starts multiplying through cell
    division, by mitosis, automatically
  • Dolly, the sheep, is the first ever clone, died
    prematurely
  • Cloning can leave a number of ethical questions
    unanswered in the 21st century

10
The West argued, the Africans died
  • The cloning scenario is only highlight of a world
    wide debate about genetic engineering of animals,
    vegetables and every thing except minerals
  • With religion, green fanaticism and trade
    interests getting involved, facts are hard to
    separate from agendas
  • The real biotech tragedy of 2002 Starvation
    deaths in Zambia because of an US-EU row over
    providing biotech (cloned) corn for famine relief

11
Part2
  • Bio-chemical Warfare

12
Biological warfare weapons
  • Anthrax
  • Cutaneous
  • Inhalation
  • Intestinal
  • Smallpox
  • Botulinum toxin
  • Bubonic plague

13
Chemical warfare weapons
  • Nerve gas agents
  • Sarin
  • Tabun
  • VX gas
  • Blistering agents
  • Lewsite gas
  • Mustard gas
  • Choking agents
  • Chlorine
  • Phosgene

14
Effects of bio-chemical warfare
  • Respiratory failure
  • Muscle contraction
  • Paralysis
  • Skin blisters and burns
  • Choking and cough leading to death
  • Formation of painless ulcers
  • Seizures
  • Abdominal pains, severe diarrhoea
  • Vomiting with blood
  • Rashes and boils
  • Flu like fever
  • Blurred double vision
  • Nausea
  • Fever, loss of appetite, vomiting

15
Part3
  • Patenting Problems

16
Issues with patenting
  • New localized law based on the acceptance of
    society/nation as well as the Govt.
  • Global scenario to be kept in view
  • Absurd ideas, techniques and material often
    obtain patents without difficulty
  • Patenting of BRCA1 (breast cancer) gene
  • Neem and neem based products
  • Basmati rice

17
Patent what??
  • Patenting cosmetics, drugs, technology, etc. is
    acceptable everywhere but not of diseases, genes,
    air, water, etc.
  • Especially the concept of patenting gene
    sequences is raising eyebrows as it is an absurd
    idea but a number of researchers and drug
    companies are doing it

18
Patenting in EU
  • The EU Biotech Directive
  • The French Bioethics Bill

19
Part4
Bio-sciences IPR issues
20
Patent vs. IPR
  • The issue of patenting and that of intellectual
    property rights should not be intermingled
    together, though both have a greater degree of
    overlapping meaning

21
Some right some wrong(kabhi ha kabni na)
  • The fight will always go on should the
    technology and ideas be protected under IPR or
    patenting
  • Some decisions will prove to be correct and will
    be acceptable, whereas some will not be accepted
    as happens with the introduction of every new
    technology or concept
  • Recall history of computers, space technology,
    cloning, etc. for more information

22
Part5
Genetically Modified Crops
23
Genetically modified cotton
  • Genetically modified (GM) Bt cotton contains Cry
    1 Ac gene
  • Higher number of bolls, reduced number of sprays
    for control of bollworms and higher yields
    harvested so far
  • Bt cotton is grown in Maharashtra, Gujarat, MP,
    AP, Tamil Nadu and Karnataka

24
Genetically modified mustard
  • If approved, Indian mustard will be the first
    genetically-modified edible crop in India
  • Packaging and labeling as per International
    standards is impossible in India since
  • Mustard leaves are sold as vegetables at every
    street corner
  • 90 percent of mustard oil is old loose in the
    country
  • Labeling and packaging will increase cost

25
How safe are the GM crops?
  • Critics say that inserting genes into plants is a
    new science and may have unforeseen side-effects
    on a plants biochemistry, such as destroying its
    natural qualities and creating natural imbalances
  • Cross pollination between GM crops and nature
    cause unwanted outcome
  • It will also lead to creation of super-weeds,
    which will be resistant to herbicides

26
Do we really need them?
  • Contamination of environment
  • Multinationals will hold monopoly on hybrid seeds
    in the future
  • Farmers will be forced to buy new seeds from big
    corporations every year
  • Even GM fodder/animal feed is in market

27
Terminator seeds
  • Seeds that do not germinate, which means they
    cannot be saved and planted again
  • Hybrid seeds function almost the same way

28
Gene jumping
  • It can result in transfer of genetically induced
    traits of one organism to related species like
    tomato, cabbage, radish, cauliflower
  • Genetically engineered or modified plants contain
    genes taken from bacteria, virus, other plants or
    animals
  • Examples
  • Corn scorpion Soyabean cow
  • Tomato pig virus Strawberry fish
  • Cabbage rat Rice human

29
Part6
Future Dark or Bright
30
What to do next
  • Present day focus is mainly on life style drugs
    and diseases like can cancer, AIDS, diabetes,
    etc.
  • There are numerous other areas and diseases
    waiting to be explored
  • Diabetes, cancer and heart disease has remained
    the biggest concerned of 20th century and a
    greatest challenge for 21st century

31
What is coming in near future
  • Development of specific organs such as eyes,
    heart, kidney, etc. is already around the corner
    and spare organs would be available in about
    5-6 years time
  • The human cloning activity is under process and
    very soon we may hear about its success, on lines
    similar to Dolly, the sheep

32
Future bio-computing or bioinformatics
  • Highly sophisticated software for
  • Mining genetic data of numerous species
  • Efficient analysis tools
  • Massive servers and cluster computers (clusters
    of 1000 and above computers)
  • High performance standalone computers
  • Massive storage devices (of the order of hundreds
    of TB)

33
Behold! The future is
  • Very soon a newly born baby shall be discharged
    from the hospital with a CD containing the DNA
    sequence for the entire genome
  • It would become possible to detect genetic
    disorders at any stage of life and checked
    whether they have any hereditary links or not
  • It is sure to find these concepts realized but it
    may take some time to bring them to reality
  • In another 30-40 years, people would be able to
    see and browse through their genomic sequence

34
Future risks
  • Difficulty in maintaining the confidentiality of
    genetic code as there would be lot of problems
    with publicly available DNA sequences of
    individuals
  • Insurance companies may ask for this unique
    code or at least a clear analysis report
    hereafter
  • Employment avenues may become much bleak if the
    code contains any damage, as resumes may contain
    a clear analysis report
  • Physically and mentally impaired persons may find
    it extremely difficult to function in a high
    competitive engineering environment

35
Future risks
  • Imparting and pursuing education would grow more
    difficult with bio-sciences and genomic sciences
    occupying compulsory position in the curriculum
  • Genetic based racism would increase due to the
    ability to cluster the people on the basis of
    genomic data
  • Bio-terrorism will also have a new chapter added
    to it in the form of genomic terrorism wherein it
    would be possible to manipulate with others
    genetic data or actual genes

36
Future risks
  • Selecting a life partner could be cumbersome as
    it would become possible to compare the sequences
    before marriage and properties of likes-dislikes
    could be easily established
  • Many states have already made matrimonial
    registration mandatory, which includes a HIV/AIDS
    clearance certificate of both partners

37
  • Scientific work bring forward both good and bad
    issues. They have to be dealt with by everyone
    keeping in view other dimensions such as logical,
    ethical and legal

38
It is a fact that
  • Till some stability is obtained, we have to take
    risks, only then we would know of the outcome or
    else how do we know about the outcome or how do
    the field grow
  • As long as it is not known as to what gene will
    do what, all medical treatments can not be assured

39
But still
  • Elders say that the future is perfect!!!
