It’s
sunny out there, ponds are drying.
And
the little tadpoles are in fear.
Moving
and jumping, waiting for the rain.
Poor!
I feel so sad, for them it’s too bad.
Nowhere
left to go, how helpless we are too.
Lastly,
poor little ones are going to die.
Being
the part of the Earth’s pie.
For
them the world seems dark.
Though
everywhere around is bright and green.
Is
there anything that we can do?
Do
they have to be in water?
Can
no one invent anything?
For
these dying poor little ones!

Empathy in psychiatry
By tcvselakuisciencedepartment September 14, 2018
Empathy in psychiatry
Tenzin Diki, XI
A Science
Psyciatry
is the medical speciality devoted to the diagnosis, prevention and treatment of
mental disorders. It has been described as an intermediary between the world
from a social contest and the world from the perspective of those who are
mentally ill. In its ongoing attempts to define, understand and categorise disorders
and determine the best treatments, the medical speciality of psychiatry is
always up against the protean complexity of our human brain.
Despite
evidence for the centrality of the doctor –patient relation in effective,
psychiatric treatment, the current research paradigm of psychiatry has paid
limited attention to the role of empathetic human understanding in routine
psychiatric treatments. There is increasing neurobiological evidence for the
importance of emotional and interpersonal aspects of treatment for patients
with mental health conditions. Inspite of the evidence for the importance of
these empathetic interpersonal aspects of psychiatric treatment, there has been
little recent discourse in the psychiatric literature about how empathy can be
effectively used in the day to day practice of clinical psychiatry.
It
is generally accepted that the modern English term ‘Empathy’ is derived from
the German word ‘Einfuhlung’ which is a term from aesthetics, approximately
meaning to ‘Feel into’ an object. According to NCBI, Carl Rogers is perhaps the
most well known for his description of empathy in mental health context. He defined
empathy as ‘To perceive the internal
frame of reference of another with accuracy and with emotional components which
pertain there to as if one were the other person, but without ever losing the ‘as
if’ condition.
Empathy
is widely endorsed as a desirable quality in doctors and is correlated with
better patient satisfactory outcomes and savings in the time and expense. It has
however proven challenging to measure empathy in medical practice or even defines
it satisfactorily.
In
general psychiatry, research attention to empathy has been very limited. A
recent qualitative study found that resonating with a person and being
available to understand them remains a key element of treatment according to
patients but other than a few extant anecdotal account, there has been very
little empirical work on empathy in general psychiatric practice, particularly
in terms of how empathy is enacted.
This
research gap is problematic, because empathy is especially important and
complex to utilize in general psychiatry without an understanding of how
empathy is enacted and used during the daily tasks of the psychiatrist empathy
remains an abstract concept rather than a practice that can be discussed,
improved and taught effectively.
Aging

Aging
Tenzin Choezin,
XI A Science
As
the time goes by a person looks in the mirror and see himself getting a
different and variety of look as the time goes. This is called aging. Aging is
the process of becoming older. As we grow old, we age and this brings a lot of
changes in person’s life.
According
to me, we grew old because of DNA oxidation. As the time passes, our bodies get
oxidized as we inhale oxygen during respiration. In this century we are not
able to find the real cause of aging. In some animals such as backward aging
jelly fish has found as way to cheat death by actually reversing its aging
process according to National Geographic. The jellyfish can return to its polyp
stage over a three day period, transforming its cell into a younger state that
will eventually grow into adulthood all over again.
Ancient remedies like Acupuncture and Herbal medication for treatment of diseases; connecting science to culture

Ancient remedies like Acupuncture and Herbal
medication for treatment of diseases; connecting science to culture
Youngzin Lhamo,
XI A Science
Treatments
for problems of the digestive system, muscle pains etc are dated long back in
the ancient times. As long ago as 25,000B.C, the Chinese treated various
digestive disorders with acupuncture. Acupuncture is a painful yet an
interesting treatment in which very thin needles are placed into the body at
key points. It is an ancient remedy, yet famous in all ways. For digestive
system, this treatment has been proven to control appetite and to reduce
stomach upset.
The
ancient Chinese also used plants to treat digestive disorders. Plants used in
this way are called herbs. The yellow underground stem of Chinese Rhubarb has
been used for more than 2,000 years to regulate digestion. Another herb used as
medicine since ancient time is garlic. The Chinese, Babylonians, Greeks,
Romans, Hindus and Egyptians all used garlic to treat various intestinal
disorders.
These
practices are healthy and cause no side effects during treatment. Acupuncture
is more popular in eastern Asian countries although it is practiced in other
countries too. Acupuncture has its own depth study especially about areas of
pinning points and its required technique. The practices of acupuncture and
herbs are visible in Tibetan communities too. All medicines provided in Tibetan
hospitals lead by Men-tsee-khang are herbal medicine. Since everything in the
world has its merit and demerit and limitations, afore mentioned practices also
has drawbacks. These treatment practices take quite along long time to heal any
curable diseases.
The
patients require lots of patience, faith and must be consistent especially in
taking the herbal medicines on time. The roots of patience are always a
fruitful result. The final outcomes are satisfactory with its root healing
power. These herbal medicines heals a disease from the root rather than curing
the symptoms like other effective dosage that heals us from the pain for a
short duration.
These
practices are convenient and beneficial. Nature is always healthy for our body.
There are many ways in which the traditional old practices edges over modern
high chemical input dosage which heals one and rises another disorder.
Hence,
believe in nature and healing power would be more stronger with your faithful
energy. I assume theses practices more significant and desirable. Look around
for some interesting news about people who has been cured from incurable
cancers and other benefits of traditional remedies for treatment of dieses.
Happiness –the childbirth

Happiness –the childbirth
Tenzin Tselha,
XI B Science
The
development of the baby since nine months or 38 weeks or 266 days passed. The
day has arrived, the gestation period. The long awaited moment of the family
arrived, filled with fear, excitement and multiple emotions. The pregnant
mother suffers the uterine contraction of the mother efforts fully for the
healthy delivery of the baby out of the comfort zone in fifteen minutes. The
process of this delivery is termed as parturition. The labour process of
childbirth comprises mainly of four stages.
Starting
witht the mother’s contraction and to the travelling of foetus down the birth
canal, expulsion and the delivery of the baby and it’s placenta. If the mother
of the baby proceeds the contraction normally, the moment of happiness and
ladoos begins for the family. But in case, the mother is not able to contract
week enough and unable to push the baby properly, labour techniques are needed.
While the contraction takes place, with each contraction, the mother should
relax for the foetus to receive oxygen. Without proper relaxation, the amount
of blood reaching the foetus becomes lesser.
Relaxation
and deep breathing will help the mother to reduce pain. The gynecologist will
even provide a mixture of half air, half nitrous oxide at the beginning of
contraction. During the delivery, the heart rate of the foetus is in between
120 to 160 beats per minute.
Normally,
the rate decreases with each contraction and comes back. If it does not return
to normal, this will be a problem which should be treated. Understand the
suffering of the mother and pay the love and care back.
Neurogenesis
By tcvselakuisciencedepartment September 05, 2018
Neurogenesis
Tenzing Thokmai,
XI A Science
The
term neurogenesis might sound like something out of science fictional movie or
something only the high educated professors would understand, however it is not
as complicated or futuristic as it may seem or sound. Neurogenesis is jut a
fancier term that simply means the creation of new nerve cells but this
creation of new nerve cell is controversial subject among the neuroscientists.
You may be wondering why? So, here is the answer.
Until
recently, most neuroscientist thought we were born with all the neurons that we
were ever going to have. It was considered that the numbers of neurons were
fixed and they did not replicate after the maturity of the brain. When we were
babies we tend to produce new neurons to help build the pathways called neural
circuits that acted as information highways between different parts of the
brain. But, the Scientists believed that the generation of new neurons during
the age of adult would disrupt the brain ability to learn and remember.
In
1962, scientist Joseph Altman was the first one who as able to provide evidence
of neurogenesis (the birth of neurons) in a region of an adult rat brain called
the hippocampus where the brain plays an important role in memory and spatial
navigation. Then in 1979, another scientist, Michael Kaplan confirmed Altman’s
finding in the rat brain after which in 1983, he found neural stem cells in the
forebrain of an adult monkey from which new neurons were formed and
regenerated.
These
discoveries about neurogenesis in the adult brain were surprising to other
researchers who did not believed that it could occur in humans. But, later in
early 1980s, scientist Fernando Nottebohm and his research team came to know
that the number of neurons in the forebrain of male canries dramatically
increased during the mating season. This was the time when the birds needed to
learn new songs to attract females. Nottebohm believed that these new neurons
helped them to remember and learn those new songs which gave rise to the idea
that the brains of mammals might too generate new neurons throughout their
lifespan.
So,
if new neurons are being formed in our so called brain then how can we
facilitate it in order to make our mind sharper and gain long lasting memory power?
Thus, many scientists say that it can be achieved through.
Exercise:
running, yoga and sports increases hormones such as testosterone which is
highly beneficial for neurogenesis and reduces stress.
Meditation:
It has been found that meditation leads to increase in grey matter density in
our brain including the hippocampus and you don’t have to be particularly
Buddhist to practice meditation. Anyone from any religion can practice it.
Nutrition:
As the saying goes “You become what you eat” is quite true because stuffs such
as blueberries and green tea are good for brain health and supportive of
neurognesis.
Rest
and No stress: It is said that stress can cause death of neurons so be careful
and just take a chill pill because you don’t want your brain to end up empty.
That’s
all for now but for some neuroscientist, neurognesis in the adult brain is
still an unproven theory. Bhut, others think the evidence offers intriguing
possibilities about the role of adult generated neurons in learning and memory.
So, this mystery will go on but my final question is “Do you believe it, or Not?”
A story of a cancer survivor
By tcvselakuisciencedepartment September 05, 2018
A story of a cancer survivor
Yangchen
Lhamo Drungtso, XI B Science
In
the United States in 2017, an estimated 10, 270 new cases of cancer wil be
diagnosed among children from birth to 14 years and about 1, 190 children are
expected to die from the disease. According to World Health Orgnaisation (WHO),
deadly disease ‘Cancer’ was defined as a generic term for a large group of
diseases characterized by the growth of abnormal cells beyond their usual
boundaries that then invade adjoining parts of the body and spread to other
organs . So, I don’t think that it is an alarming piece of news that whole
world needs to know so that we can address the issue soon.
Have
you ever thought in the same manner and talked about these issues with your
peers? Or have you ever dreamt of
becoming a life saver? For some, the answers may pop out to be a big fat “NO”.
But, for me, as an eleventh grader from TCV School Selakui, I have dreamt of
becoming a pediatric oncologist who could help children escape children from
the inevitability of death due to cancer.
One
fine morning, as I searched around my table to find my important research
paper, my eyes caught a s statement by the well known Indian oncologist
Siddhartha Mukerjee who talked in one of his interview in which she said, “Anyone
who has spent time the oncology clinic understands that it can be if you look
at it in a certain way a very depressing place. Perhaps the most striking sign
of that is when young residents and fellows say, “I don’t want to become an
oncologist because everyone dies. “It is absolutely not true”. And my eyes
drawn towards that e last sentence which brings a ray of hope that can
illuminate the lives of many cancer patients. Every year, 300, 000 families
around the world will hear, “Your child has cancer”. And I can’t just sit,
watching these heart wrecking news and ending up as a mere oncologist. It
carries a huge responsibility for a future oncologist like me to take the road
less travelled and to explore for an effective treatment.
Beside accidents, cancer stands for
the second leading cause of death in children youndger than 15 years of old. Children
having cancer treatment have to overcome unbearable treatments like radiation and chemotherapy that make life
unbearable to live. And parker is one of the children with cancer. This life threatening
moment happened at the age of six and half years. On the morning of March, 2013
he got an injury to his left hip but never knew that this small injury would
bring a huge loss and burden to his family. Over the following weeks the pain
grew intensely, his ability to walk became impaired, he developed diarrhea and
his eyes began to bulge out. Not only that, he woke up in the middle of the
night with low grade fever and his legs started hurting. So, he was sent back
home from his boarding school. They consulted many pediatricians and Parker
finally had an X-ray. After hours of observation and analysis, the pediatrician
came up with his X-ray explaining them that, his hip was normal but there were
some infections in his body. To get a CT scan for confirmation was going to
take a lot of the time to schedule.
On
the tenth day of April, 2013, before their morning alarm rang, they were
awakened by the shrill cry of Parker. They rushed him to the ER Labs at Rady
Children’s Hospital in SanDiego. Since, the labs were closed, there were no
patients in sight. Parker’s mother told the doctors about his symptoms and
handed the lab results. While waiting for the doctor, his mother craked jokes
and acted as if she wasn’t scared at all. Then the doctors came with her eyes
scarlet, swollen as if she had wept. She explained that there was a hught lump
on Parker’s left kidney but they were unable to know what the lump was. So, They
met with an oncologist and he explain to them that Parker had stage four
neuroblastoma. Among the top fiev pediatric cancers, neuroblastoma is a solid
tumor that arises from immature nerve cells in young children. It is found
primarily in children younger than the age of 5 years old. It mostly begins in
the adrenal glands and makes up 7 percent of childhood cancers in the U.S.
The neuroblastoma in Parker started
on his left adrenal glands and metastatised to his bone and 87% of his bone
morrow. Thought the chances for his survival were only about 20%, Parker fought
it fiercely as he endured then hours of tumor surgery, eight rounds of thermotherapy,
fourteen rounds of radiation, ten cycles of a painful mouse antibody, the so
called 3F8, and finally harvested 500 millions natural killer cells from this
father. Through many sacrifices, a seven year old child has survived. During
that time, a cancer survivor named Aiden who has once suffered from state four
neuroblastoma gave parker immense hope during his dark days and helped him to
get in touch with Memorial Sloan Kettering Cancer Center (MSKCC) in New York.
Now
the big question arises. “How can we help these cancer patients?” Even thought
we have treatments for this, we are still facing problems with intensive treatment
that carries many unwanted side effects and even present possibility of the
recurring tomor. Thus, the young future scientist and oncologist needs to
ponder over this situation and find new solution. Finding better ideas and
innovations to cure this deadly disease is the need of the hour. Besides this
its our responsibility to lift up the spirits of these innocent children by
nurture then with hope, helping them to tolerate with the situation and to give
then a new life.
“Support
the fighters
Admire
the survivors
Honor
the taken
Never,

My Life and NIPAH Virus
By tcvselakuisciencedepartment September 04, 2018
My Life and NIPAH Virus
Tenzin Lhadon
I
thought that i had the greatest family ever...
Actually
I had, until he came into my life...NIPHA VIRUS!.He was something that i can't
control, something unacceptable and something.... horrible!
I
lived in a village called Sungai Nipha in Malaysia with my parents and my
younger sister who is barely a year old. As for me, I am Gina, a ten years old
girl...I was everyone’s favourite and laughter. I use to help my father with
his farm and my mother with her animal husbandary..When i get free time i use
to help my uncle and aunt with their shops and i also use to spent time with
the grandparents listening to their folk tales....I had no friend that i could
play with because i was always busy helping the elder one accept for Ream,My
cute baby pig..She was all i have as a friend.
Everything
was going fine and happy...But one dreadful evening, my mother got sick. She
had very high fever and she coughed a lot..We showed her to doctor and they
said it will go away quickly..We gave her the medicine that doctor prescribed
and slept. Next morning, She was quite better than last night so she went to
work. We thought it was not that much serious as it happened to be.Day after
day,she keep having headache and high fever. She keeps coughing a lot and
somethimes she can't even breadth..We called our Uncle and aunt, they carried
her to the city for a better doctor.I was left with my Ream and aunt..I got so
worried and scared..Scared thinking that she will leave me alone and
forever..For the whole two weeks i had no one that could nurse me to sleep..My
aunt barely comes to me as she got super busy with her shop.All i had as my
parent and as my family was Ream..she was all i had.
After
two weeks, I hurried outside with joy and excitement to meet my mother once
again...I found my father and uncle crying and sobbing until they saw me and my
father came running towards me and hugged me..That time i didn't feel the
warmth of his body but the cold sorrow that he brought with him..And my first
greatest love and laughter was snatched away from me..
Along
with my father some of the nurses and doctors came for check up and took some sample of what my
mother use to have and wear..After some days they came again, and this time
they has the reason behind why my mother died, the newly found desease NIPHA
VIRUS!!.They told us that it was their first time knowing such kind of virus as
they never had such desease before..They said they don't have cure right now so
all we could do is to prevent it before anything gets wrong..They started
going all around the village in search
of infected people..Not many days after my mother died,Someone was also got by
that virus and then day after day many poeple got sick and we came to know that
this virus can spread though human to human through direct contact. ,many were
dead and many were scared..The doctors
can't do anything,they just gave hopes to those who were dying and created
awareness to those who were scared and was fully stranger to such kind of
desease...
Months
passed and the doctors and the researchers got to know more about the
virus..They found that the virus can spread among humans and to those who have
close contact with infected pigs thus they wanted all the pigs in our village
to be killed.Even my Ream...I told them
she was not infected and dangerouse..i told them she had nothing to do with
that virus..i told them i need her and I told them she is a part of my
family.But no one listened, even my father.They took away all the pigs and
killed them without a single mercy..And then
our village has became a cemetry with full of unburied dead body of
humans and pigs..people were scared about there unknowing death..They don't
want to be captured by that deadly desease and they they don't want to die
being a host of that virus..Most of them moved to city and so my uncle and aunt
did.They carried my little sister with them and promised my dad to take care of
her and raise her well..Our village were under big research and was also in
great danger..Half of our poeple were dead and one forth went to city.people
like me and my father were left helping the doctors and researcher.
I
once dreamed of my own family with my own parents.I once wish for my parents to
live long so that my children will have
someone they call as grandparents. I wished to have a wonderful and a happy
life.But now all those dreams and my wishes washed away with the endless blood
of my poor villagers and the animals.
My
father wants me to go with my aunt,but i
don't wanna let him die alone..i wanted
to take care of him until he take his last breath.Day after day my father got
worse and he was near his death.All i could do is watch him dying, suffering
and crying out in pain so much.I couldn't even guide my parents well to their death bed.I couldn't
get good time to give them a nice farewell and i couldn't get enough time to
tell them how much i love them and how much i will miss them..All i could do is
cry, cry and cry my lungs out.
People
sent by the government gave us food and shelter..They had been very nice to us,
specially Dr.Clay.He was with me when i was hopeless and crying endless after
my father's death."Thats enough!!"I shouted myself by the river under
the full moon."I had this enough of you...you took away all i had..All my
poor family and my friend..Now i had no one to rely upon and its all your
fault..What have i done to you that you could be so rude to me like
this..Why??"I cried talking to myself."Ahem..sorry to interrupt your
crying but can I join you??"This was the first time meeting with
Dr.Clay.He sat beside me.."This is nobody's fault...And if you really want
to blame someone.Then blame him."He pointed to a fruit bad hanging on a
tree.."We were first clueless about this dreadful desease..Nobody knows
until your mother came.You can't blame yourself or no one..And not only you but
most of the villager's lost there loving family..Some are orpan like you,some
lost there children..And some are not wanting this sad story of there life..Not
only you but all are struggling hard and wanting this to end fast....Listen,
you have to be strong and and never let that virus catch you.."He was
right after all...I have been only worring about myself and my family..I have
been so selfish...I couldn't waste my limited life crying and regreting what
happened in past..I have to feel lucky that i am still alive and have to make
the best out of it.."Can you please help me??"i asked.And he
nodded."I have to go to city...i have to go to my aunt and uncle..Can you
please do that for me??"I plead."What about coming with me and being
something that could help them...I am unmarried and have no family...You could
be a family..what do you say??"He suggested.."Thank you so much for
your kindness..I would love to do so.."i agreed and decided to spent my
life with him...
Year
passed and my village became smaller with healthy people but leaded by hundred
death of my poor villagers.That virus has spread among country to country by
the time..Thousand were died in Bangladesh, Singapore and India.We still hasn't
found any cure for that virus and still many people are dying around the
world..And recently there was an outbreak of Nipha virus in a place called
Kerela in India.
We
still can't stop and eliminate that virus forever.It keeps spreading and
spreading killing thousand of innocent poeple.Me and my group went to diffrent
part of the world where Nipha has attacked.We help as much as we could and
helped as much as we can..
"Dr.Gina,
our next visit is Kerela,India"My assistant told me.."Sure...Lets do
this thing!....We don't know how many people we will be able to save and how
many poeple will die infront of
us....But we still need to help them and do whatever we can to prevent it
because.."i shouted.."PREVENTION IS BETTER THEN CURE!!!"we all
shouted....
A disappearing paradise

A disappearing paradise
Tenzin Tsomo XI A
Rainforests since time reminiscent have
been a place of great wonder and curiosity. These places are known to have the
most diverse and vibrant forms of living species in the world as, these rich
biomes are the natural habitats of about three-fourths of known plant and
animal species in the world. Mostly found in Latin America( One fourth in
Brazil), Southeast Asia, Africa, and in some Pacific islands, tropical
rainforests as well as temperate rainforests found in some continents near the
pacific are the most fascinating places of extensive research and adventure for
zoologists around the world.
We humans, rely on rainforests for the
production and direct consumption of a large variety of organic products. Also
a large number of vegetables and staple crops which are prevalent in our daily
diet are originally from the rainforests. One of the main attractions in the
rainforest resources is the exotic amount and variety of wood found in these
places. This accounts to the great demand for logging of rainforest trees for
commercial purposes. Other than that rainforests are major contributors to the
terrestrial global carbon pool or to put
it more simply the carbon cycle. They are beneficiary for not only humans but
for every living organism surviving till now.
Sadly, the human greed for the
rainforest resources are causing great changes and are rapidly taking toll on
the animals and plant species living in them. In the ancient times these biomes
were cleared/or in more literal meaning, ’razed to the ground for farming
purposes through the method of shifting cultivation. This practice has
destroyed great tracts of rainforest areas.
But the shift to the modern twenty first century has posed a surprising
and an even greater threat for the rainforests. Such type of threats, which may
eventually lead to the extinction of these great natural habitats.
With reference to the conservation groups, it
is estimated that globally, the equivalent of two football fields of
rainforests (about 2.5 acres or 1 acre )
is destroyed in a passing second and each day amounts to an area larger than
New York City or about 214,000 acres of rainforest area! . The destruction is
paving the way to the extinction of more than 100 species a day and about 20
percent of the surviving species within a generation. The countermeasures for
protecting the rainforests can be performed but if we belittle the action plan,
the chances of saving these natural paradise is simply ‘zero’.
It is in our
hands, whether we choose to wait and watch or, do something today that our
future world will thank you for.
