National Symposium On Immunobiotechnology at Nainital

National Symposium
On
Immunobiotechnology
December 17-19, 2010
Venue: Institute of Biotechnology
(G.B. Pant University of Agri. & Tech.)
Patwadangar -263 128 (Nainital)
Uttarakhand, India

Introduction
Immunity is the resistance of body against extraneous etiological factors of disease, which is afforded by the interaction of chemical, humoral and cellular reactions in the body. This is an integral part of the body without which one cannot think of life. During the process of evolution, nature has provided this defence mechanism in the body of all living creatures particularly of higher animals and man that protects them from physical, chemical and biological insults. It can be classified as natural or
paraspecific and acquired or specific immunity. Due to increase resistance in bacteria, the efficacy of antibacterial drugs is reduced, in such circumstances immunomodulation with an aim to increase the immune power of body remains only alternative to control the infections.

Various types of immunomodulatory products are described including physiological products, chemicals, microbial products, herbal products etc. of which herbal immunomodulators based on ancient Indial Ayurveda System of medicine were more effective without causing any side effects or drug related problem.immunomodulation is one of the most important alternatives in order to control the diseases with additional advantages of amplifying specific responses to vaccines. The immunomodulatory compounds also offer the prospects of reversing immunosuppression caused by stress, viruses or environmental pollution. The convention aims to bring researchers, scientists and students together to exchange
and share their experiences, new ideas and the research outcome through the presentation and discussion of papers of all possible aspects of Immunobiotechnology.

Society for Immunology and Immunopathology

The Society for Immunology and Immunopathology (SIIP) was established with the aim to provide a forum for its members to participate in conventions/symposia/workshops/ training etc. and to provide a recent updated literature in the form of journal/newsletter.

100 Facts About DNA

Did you know….

1. DNA stands for deoxyribonucleic acid.
2. DNA is part of our definition of a living organism.
3. DNA is found in all living things.
4. DNA was first isolated in 1869 by Friedrich Miescher.
5. James Watson and Francis Crick figured out the structure of DNA.
6. DNA is a double helix.
7. The structure of DNA can be likened to a twisted ladder.
8. The rungs of the ladder are made up of "bases"
9. Adenine (A) is a base.
10. Thymine (T) is a base.
11. Cytosine (C) is a base
12. Guanine (G) is a base.
13. A always pairs with T in DNA.
14. C also pairs with G in DNA.
15. The amount of A is equal to the amount of T, same for C and G.
16. A+T = T+G
17. Hydrogen bonds hold the bases together.
18. The sides of the DNA ladder is made of sugars and phosphate atoms.
19. Bases attached to a sugar; this complex is called a nucleoside.
20. Sugar + phosphate + base = nucleotide.
21. The DNA ladder usually twists to the right.
22. There are many conformations of DNA: A-DNA, B-DNA, and Z-DNA are the only ones found
in nature.
23. Every single cell in our body has DNA.
24. DNA is the "blueprint" of life.
25. Chromosomal or nuclear DNA is DNA found in the nucleus of cells.
26. Humans have 46 chromosomes.
27. Autosomal DNA is part of chromosomal DNA but does not include the two sex chromsomes -
X and Y.
28. One chromosome can have as little as 50 million base pairs or as much as 250 million base
pairs.
29. Mitochondrial DNA (mtDNA) is found in the mitochondria.
30. mtDNA is only passed from the mother to the child because only eggs have mitochondria, not
sperm.

53. In 2003, the final draft of the human genome was completed.
54. The human genome sequence generated by the private genomics company Celera was based
on DNA samples collected from five donors who identified themselves only by race and sex.
55. If all the DNA in your body was put end to end, it would reach to the sun and back over 600
times (100 trillion times six feet divided by 92 million miles).
56. It would take a person typing 60 words per minute, eight hours a day, around 50 years to type
the human genome.

Lets Unite Bio Sciences Professionals | We are under threat

Dear Friends,

Today we are forced to write this!!

Yes!! We are under threat

Our Bio Sciences Community is being constantly lured by the high paying jobs available in other sectors such as IT. Many of the talented professionals from our field are making a switch to the IT/Alied sector. And we cannot sit back and do nothing. All those who have a myth that Other sectors pay you higher then they must know that there you get a Job and not a career. That is you may get a job but there will be no growth, no professional achievement. All your life you will be treated as an underdog.

In a recent survey of a IT Company's Bio Sciences staff we found that 90% professionls again wanted to come back to BioSciences field since there was no career growth in IT sector for them.

Our Younger Generation is Lacking Awareness about this field !!

Friends, we all need to create awareness that Bio Sciences is a very important field and this world may not have existed if Bio Sciences was not there. Bio Sciences is the mother of Pharmaceutical siences and BioTechnology. Be it Botany, Zoology, Biotech, Microbio, Biochem, Mol Bio, immunology, Bioinformatics, every field is very important. Bio Sciences is not a field which is opted by people who are scared of mathematics rather its a bunch of bio engineers who make life simpler & healthier for the rest of the population.

Are BioSciences jobs scarce?

If some one says you that BioSciences gives you lesser job opportunities then the actual fact is BioSciences is a knowledge based science. No one with just 6 months training can do it. It requires passion and dedication.

Some stats:

• Every Month BioTecNika posts: 600+ JRF/SRF vacancies
• That means 7200+ JRF Vacancies/year
• Every Month We post 100+ Company Jobs which means 1200+ jobs in various Companies

That means 8400+ jobs are up for grabs every year. All you need is passion, dedication and continued efforts to counter every situation.

Is Entpreneurship an Answer?

The Answer is Yes. One of the Most Important ways to Overcome this scarcity of jobs is through Entrepreneurship. So if any one among you are planning to open up your own Biotech/ Agri Biotech Company then do let us know and we will do our best to assist you.

Are the Posts Fixed?

we have come across many of complaints where the post was fixed or the under talented candidate was appointed due to red tapism.

How to fix this issue?

Friends all this is happening because we are not united! Not united against this corruption! Not comitted towards our very own field.

Lets Get United!!

Yes we need to get united no mater what!! So we urge every one of you to invite all your friends to BioTecNika and helps us expand this community. Once we are united we can make things possible.

Chemistry Of Cooking - - - A Biochemist Explains The Chemistry Of Cooking

A biochemist and cook explains that cooking is all about chemistry and knowing some facts can help chefs understand why recipes go wrong. Because cooking is essentially a series of chemical reactions, it is helpful to know some basics. For example, plunging asparagus into boiling water causes the cells to pop and result in a brighter green. Longer cooking, however, causes the plant's cell walls to shrink and releases an acid. This turns the asparagus an unappetizing shade of grey.
 

You love to cook, but have you whipped up some disasters? Even the best recipes can sometimes go terribly wrong. A nationally recognized scientist and chef says knowing a little chemistry could help.

Long before she was a cook, Shirley Corriher was a biochemist. She says science is the key to understanding what goes right and wrong in the kitchen.

"Cooking is chemistry," said Corriher. "It's essentially chemical reactions."

This kind of chemistry happens when you put chopped red cabbage into a hot pan. Heat breaks down the red anthocyanine pigment, changing it from an acid to alkaline and causing the color change. Add some vinegar to increase the acidity, and the cabbage is red again. Baking soda will change it back to blue.

Cooking vegetables like asparagus causes a different kind of reaction when tiny air cells on the surface hit boiling water.

"If we plunge them into boiling water, we pop these cells, and they suddenly become much brighter green," Corriher said.

Longer cooking is not so good. It causes the plant's cell walls to shrink and release acid.

"So as it starts gushing out of the cells, and with acid in the water, it turns cooked green vegetables into [a] yucky army drab," Corriher said.

And that pretty fruit bowl on your counter? "Literally, overnight you can go from [a] nice green banana to an overripe banana," Corriher said.

The culprit here is ethylene gas. Given off by apples and even the bananas themselves, it can ruin your perfect fruit bowl -- but put an apple in a paper bag with an unripe avocado, and ethylene gas will work for you overnight.

"We use this as a quick way to ripen," Corriher said. Corriher says understanding a little chemistry can help any cook.

"You may still mess up, but you know why," she said. When it works, this kind of chemistry can be downright delicious.

WHAT ARE ACIDS AND BASES? An acid is defined as a solution with more positive hydrogen ions than negative hydroxyl ions, which are made of one atom of oxygen and one of hydrogen. Acidity and basicity are measured on a scale called the pH scale. The value of freshly distilled water is seven, which indicates a neutral solution. A value of less than seven indicates an acid, and a value of more than seven indicates a base. Common acids include lemon juice and coffee, while common bases include ammonia and bleach.

WHY DOES FOOD SPOIL? Processing and improper storage practices can expose food items to heat or oxygen, which causes deterioration. In ancient times, salt was used to cure meats and fish to preserve them longer, while sugar was added to fruits to prevent spoilage. Certain herbs, spices and vinegar can also be used as preservatives, along with anti-oxidants, most notably Vitamins C and E. In processed foods, certain FDA-approved chemical additives also help extend shelf life.

Younger Brains Are Easier to Rewire -- Brain Regions Can Switch Functions

Younger Brains Are Easier to Rewire -- Brain Regions Can Switch Functions
A new paper from MIT neuroscientists, in collaboration with Alvaro Pascual-Leone at Beth Israel Deaconess Medical Center, offers evidence that it is easier to rewire the brain early in life. The researchers found that a small part of the brain's visual cortex that processes motion became reorganized only in the brains of subjects who had been born blind, not those who became blind later in life.

The new findings, described in the Oct. 14 issue of the journal Current Biology, shed light on how the brain wires itself during the first few years of life, and could help scientists understand how to optimize the brain's ability to be rewired later in life. That could become increasingly important as medical advances make it possible for congenitally blind people to have

Cleaning Infected Blood - Biologists Develop Machine To Remove Viruses From Blood

infectious disease experts designed a machine called the hemopurifier. It works much like a dialysis machine, using thin fibers to capture and remove viruses from the blood it filters. The machine requires the drawing of blood through an artery, which is sent through a tube into the machine, then back into the body. It can treat a number of illnesses.

Every day, 14,000 people are infected with HIV, the virus that leads to AIDs. There's no cure, but now a breakthrough -- a machine that could clean blood, keeping more and more people alive longer.

"I remember lying in bed thinking, 'I am going to die. I'm going to die. I feel so sick.' And I remember thinking laying in that bed, 'And I know exactly what it is,'" HIV patient John Paul Womble, told Ivanhoe. HIV could kill Womble. He watched his father die from the virus and now he is living

Mumbai Boy won a reality TV show to fund his dream stem cell research

Caezaan Keshvani is currently enrolled in university in New York, USA. Before he began his PhD programme at SUNY Upstate Medical University in Syracuse, he studied at University of Sheffield, UK. What made this all possible for this bright young man who had all but given up hope of ever studying abroad? Winning a reality television show.

Raised in Mumbai, Caezaan's story is a little different from the thousands of Indian students who head abroad each year. After completing his CIE A levels, he planned to head abroad to study. As he planned his next step, tragedy struck. His father, a doctor, was seriously injured in the train bomb blasts in Mumbai in 2006 and most of the family savings were used up for the multiple surgeries he had to undergo. As his study abroad hopes gradually dwindled, Caezaan learned of a reality show that offered the winner a 100-per cent
