Sir Joseph John Thomson
(Discoverer of Electron)
S
ir J.J. Thomson, a British scientist,
was studying discharge of electricity
through gases. He observed that when
an electric current is passed through the
tube, the negative electrode (cathode)
emits radiation, attracting a photographic
plate. These cathode rays are particles
and not electromagnetic radiation, since
they have mass. Thomson called them
corpuscles, and they later became known as electrons.
Thomson created electric and magnetic fields around the discharge tube
and studied how the rays bend. Using these methods, he determined the
ratio of charge to mass, from which he argued that electrons were sub-atomic
particles and negatively charged. If electrons were negatively charged subatomic particles, there must be an equivalent positive charge somewhere to
make the atom electrically neutral.
Thomson proposed that the atom could be like a watermelon. With positive
charge filling the volume of the melon and the negative charges (electrons)
embedded in it like the seeds! Now we know this to be an
erroneous concept of atomic structure. However, his
discovery of the electron, leading to the atomic structure
in terms of positive and negative charges, is a milestone
in science.
•
Born in Cheetham Hill, a suburb of Manchester on
December 18, 1856.
•
In 1876, Thomson won a scholarship at Trinity College,
one of the most prestigious of the colleges of
Cambridge University.
A simple cathode ray tube
•
In 1880 he completed graduation and stood second (behind Joseph Larmor).
•
Became Cavendish Professor for experimental physics at Cambridge in 1884. Young Thomson was the third Cavendish
Professor (following Maxwell and Lord Rayleigh). He held the post till 1919.
•
Awarded the Nobel Prize in physics in 1906 for his research on the conduction of electricity through gases.
•
Honoured Knighthood in 1908 - the highest honour in England.
•
He was President of Royal Society during 1916 – 1920.
•
In 1918 he was chosen Master of his old college, Trinity.
•
Died in Cambridge on August 30, 1940.

eems to be interesting, but true. As nevertheless to say,
today children are facing many problems in their daily life
due to the lack of nutrients. This deficiency of quality eating
can lead to blood pressure, beriberi, heart diseases etc at a
very young age.
According to one report by World Health Organisation,
about two thirds of strokes and half the incidence of heart
disease are attributable to raised blood pressure. Globally,
high blood pressure is estimated to cause 7.1 million deaths,
about 13 per cent of the total and about 4.4 per cent of the
total chronic disease burden. Results of this latest study, that
examined data gleaned from children aged between three and
six years old in 95 families over a period of eight years, showed
that children who ate a low-fat diet rich in dairy foods, fruits
and vegetables had better overall blood pressure.
Study author, Lynn Moore, associate professor of
medicine at Boston University School of Medicine commented:
“The findings support the idea that establishing a healthy eating
plan as early as preschool may have long-term health benefits.
Children with lower blood pressures in adolescence are less
likely to develop hypertension as young adults.”
These latest findings will fuel the already burgeoning
functional dairy market. Dairy foods are currently one of the
biggest contributors to the growing functional food market.
Together with cereals and spreads, yoghurts and yoghurt drinks
accounted for around 87 per cent of the UK market’s value
over the 12-month period, according to a recent Key Note report.
Recent innovations in the dairy sector in India include Tetra
Pak yoghurt drink, flavored milk, and various types of UHT
milk (Toned & Diet). While findings from a recent study on a
milk peptide developed by Dutch dairy ingredients firm DMV
International suggest the product reduced blood pressure in
people with hypertension. For the US study, researchers set
out to investigate if the DASH (Dietary Approaches to Stop
Hypertension) diet developed by the National Heart, Lung and
Blood Institute (NHLBI), would be as effective in children as it
is in adults in lowering blood pressure.
More than 15 per cent of school-aged children in the
US diagnosed as overweight and obese, and the risk of
developing chronic diseases including diabetes and high blood
pressure increases significantly. New blood pressure guidelines
for children set by NHLBI brought to light the strong correlation
between childhood obesity and the incidence of hypertension
within that population, and earmarked childhood hypertension
as a significant health issue.
We in India also need to take steps to address this
situation soon, else we are moving towards becoming a country
where young adults are plagued with diseases. So parents
should ensure that their child should take right dairy products
which provide the nutrients for their growth.

he treatment ffg
of cancer today is a multimodality treatment
where more than one modality of treatment is used. Almost
all cancers are treated with at least two modes of cancer
therapy while a fairly large number of patients receive three
or even more forms of treatment to fight cancer. Treatment of
cancer needs a close consultation between the surgical,
radiation and medical oncologists, who are the specialists of
surgical oncology (cancer surgery),chemotherapy and
radiotherapy respectively and the oncological pathologist.
Hence all patients should be seen by a team of oncologists
consisting of all these specialists to plan the treatment, before
starting the therapy.
T
The various modality of treatment of cancer are as follows
• Surgery
• Chemotherapy
• Radiotherapy
• Hormonal therapy
• Miscellaneous therapies
• Recent Advances
SURGERY
Surgery is the main mode of therapy in most of the
cancers, especially those affecting the solid organs of the body.
Surgery is the mainstay of treatment in the following organs
• Head and neck tumors
• Breast cancer
• Brain tumors
• Lung cancer
• Cancers of intestines
• Endocrine gland tumors
• Cancers of muscles and bones
• Genitiurinary tract tumors
It can be used in the following settings
•
Curative -where the complete disease is removed with
an intent to cure cancer
•
Debulking- here as much of the cancer is removed as
possible, to reduce tumor burden
•
Biopsy –surgery may be performed for biopsy and to
reach a diagnosis
•
Palliative -here surgery is done to combat the
complications caused by cancer or the treatment, like
in obstruction, severe infection or bleeding
Principles of Surgery
• To remove the complete cancerous part
• To remove a clear margin around it
• To remove the local lymph nodes along with the organ
or part of the organ being removed
• To ensure minimum handling of the tumor
VIPNET NEWS
•
To reconstruct the organ or limb operated to maintain
continuity or function
•
To ensure cosmesis with minimum functional disability
without compromise in the extent of clearance of
cancer
Contraindications for Surgery
Definitive major surgery should not be performed in the
following circumstances
•
Distant spread of disease
•
Poor general condition of the patient
•
Extensive local spread
•
Disease which cannot be reconstructed after excision
•
Where there would be extensive functional or cosmetic
defect
•
Where the survival of the patient is expected to be
very short
Organ Preserving Surgery
With advancement of surgical skill and the use of
chemotherapy and radiotherapy, extensive surgery is now a
days being replaced by procedures where the organ is being
preserved. This is especially being practiced in cancers of
breast, voice box (larynx) and the urinary bladder. Amputation
as the treatment of cancers of muscles and bones has been
replaced in most cases by limb preserving surgery where the
affected part including the joint is excised and replaced by
metallic prosthesis.
Minimal Access Surgery
Incision less or minimally invasive surgery is being
practiced for cancer treatment also these days. Commonly
called laproscopy, this is used in cancers of the intestine and
other abdominal organs, lung (thoracoscopy)and esophagus
(mediastenoscopy) .Here telescopes mounted with fibre-optic
lights are used to enter the body cavity while surgery is
performed under video monitoring. Here the incisions are very
small so the postoperative recovery is faster.
Reconstructive ( plastic )Surgery
Plastic surgery is often used in surgery of cancer. Common
sites of its use are head and neck tumors, and in cancers of
breast, larynx and muscles and bone. Common procedures
performed are to provide skin cover, loss of inner lining, bone
or muscles. Breast reconstruction is most commonly used
besides transfer of muscles in limb saving surgery.

Water Water everywhere, but not a drop to drink….says a
rhyme. The Ocean is full of water but is of no use to quench
thirst. In like manner, a rat living in a warehouse full of grains
to fill its stomach is not satisfied with what is available.
Scientists have wondered as to why rat venture out to seek
food when all the food is available in the warehouse. The
mechanism, recent studies have pointed out may, lie in its
brain and the reason is to ensure concoction of proteins.
The food that we eat is not just for taste or to quench
hunger; but is essential to maintain our bodily system. One of
the essential bodily needs is protein. Indeed after oxygen and
energy the third most important need of animals are protein!
Therefore it is obvious that the food that we eat must contain
those supplies the ingredients our body needs to make proteins.
These protein ingredients are called “amino acids.” We need
proteins to grow in size. Well actually we need protein to grow
our hair or even our fingernails! Proteins are also necessary
for a wide range of general body maintenance tasks, including
the replacement of worn out cells; without which we will
obviously die. Proteins are that important.
However, at times the meals that we have may not have
all the ingredients. For example corn does not provide all the
necessary protein-making ingredients- ‘amino acids’. What
happens in those disquieting cases? Scientists have found
out that evolution has construed a mechanism in our braineuphemistically called as ‘Protein Police’. The brain’s “protein
police” are on the look out for shortages of essential amino
acids. Some foods, including many animal products, contain
essential amino acids – and when the protein police detect
these amino acids, they are happy and keep quiet. Most plant
proteins, however, are missing at least one of kind of essential
amino acid. By combining the right plant foods - like when
humans eat beans with rice – you can get the right balance of
amino acids from plant sources.
But people with certain health problems, as well as
people who have access to a limited variety of foods, may
have their food urges influenced by the protein police in their
brains. In such occasion the brain’s protein police become
active and induce carving. On the other hand when we eat rice
and vegetables, such as beans, the “protein police” in our
brain is quite content and take no notice because we are eating
a meal that contain adequate amino acids.
In the new study, the scientists discovered that animals
and yeast use a similar technique to detect protein building
VIPNET NEWS
blocks and this may be the reason that rats are on the lookout
of varied food materials even though they may have access to
unlimited grains in the warehouse. These interesting
phenomena have come to light through a study that investigated
the biological chemistry behind the “protein police” in the brains
of mice and rats. If certain amino acids are missing from their
food, the rodents’ brains can detect the deficiencies 20 minutes
after they start eating. By studying wild and laboratory animals,
scientists are learning more about how the protein police
operate to try to avoid amino acid deficiencies. The fact that
many different creatures, from primitive yeast to humans, have
a similar ability to detect shortages in protein-making
ingredients highlights the importance of maintaining the ability
to build proteins.

It was the cold morning of 1st Dec 2045, Dr. Pavitra Bajpai a
senior researcher at All India institute of Para-Science New
Delhi, was shocked by the news from graveyard of district
Jaunpur in Uttar Pradesh about the missing of three dead
bodies of young students.
Such news about missing of dead or alive young intelligent
students were common during the decade of 2040’s and Dr.
Pavitra along with other scientists leading India for the mission
about missing people in collaboration with NASA department
of Para-Science to reveal the
mysteries about missing youngsters
from different parts of the world.
According to the statements of
eyewitness & media coverage it was
clear that some UFO (Unidentified
Flying Objects) like objects were
observed near the missing peoples
at the time of their disappearance
with a flash of white milky light.
Scientists/Researchers concluded
during their investigations that
some UFO like objects are capturing
youngsters alive or dead by Tele-transportation technique- an
ultra advanced modern technology to transport a body (mass)
by converting it into energy and again back to materialistic
body.
Prof. John D’souza, a senior scientist and researcher at
institute of Para-Science New York, introduced the concept of
Tele-Transportation but it was impractical for the present
scientific knowledge of mankind on earth, according to Prof.
D’souza when highly energized photons(unit of light) strikes a
body then their atoms convert into energy by absorbing extra
energy from photons.
During investigations Dr. Pavitra observed that on joining different
points on map from where news of missing youngsters were
reported, it was found that majority of lines joining targeted
places intersects over the region of Baramuda triangle – a
mysterious triangular region in Atlantic Ocean near Florida
state of USA, none of the ship or aircraft entered this region
was recovered till date, even electrical or electromagnetic signals
fails to return back from this region.
Now the mystery about the missing people was somewhat
clear that UFOs are capturing youngsters through Tele-
VIPNET NEWS
Transportation to examine their brain as the bodies recovered
from imprisonment of UFO were found lacking only the language
center of brain, may be UFO officials trying to communicate
but we cannot afford human lives for such communications
and Baramuda triangle is the main center for UFO, scientific
knowledge about Tele-Transportation is confined and nobody
knows further about Baramuda triangle except that air-ship or
water-ship could not pass through mysterious Baramuda
triangle as it engulfs any body which enters this region.
Thus around the globe scholars and
scientists are still watching telecast
of missing people stories but are
helpless to help them due to
limitations of scientific knowledge.
All were waiting for further scientific
development and investigations to
solve the mystery of missing
youngsters and stop it, as even the
most ultra advanced radars on earth
could not record the activities of
UFO due to inferior technology. No
audio or video signals transmitted
returns back from Baramuda region so the mission was mainly
centralized to Tele-Transportation technology.
Finally on Jan 16, 2048 NASA team of mission missing people
were succeeded in developing an electronic chip – a device
which utilize heat energy released by human body to charge
the compact semiconductor type cells which in turn produce
electro-magnetic field around a body capable to detect and
deflect the photons (energy packets of light) in this way not
allowing photons to fall on any human being having LPC on his
wrist, thus offering hindrance in Tele-Transportation of peoples
by UFOs for their examinations. It was made mandatory for
every human being around the globe to have life protection
chip (LPC) on their wrist to protect themselves from TeleTransportation by any UFO. In this way news regarding missing
people come to an end and people around the globe enjoyed
sigh of relaxation, LP chip was the biggest achievement for
the mission “Missing People” but the mission is still incomplete
and will proceed with 24 hour high-tech observation around
Baramuda triangle to seek dead bodies of missing people.
Mission Missing People is the long-term fight between UFO
officials and man on earth for their existence.
