3. St. Xavier's College, Kolkata

3. St. Xavier's College, Kolkata Moving two places up from last year is St. Xavier's College, Kolkata.
 
Named after St. Francis Xavier, a Jesuit saint of the 16th century, who travelled to India, St. Xavier's College was founded in 1860 with just 40 students.

It is an autonomous college affiliated to the University of Calcutta.

After gaining autonomous status in July 2006, it also came to be known as the first autonomous college of West Bengal, India.

The College offers UG and PG Courses under five faculties, namely Arts, Science, Commerce, Business Administration and Education and has close to 5000 students under its roll.

The college also owns the credit for having a commemorative stamp depicting the college campus issued by the Indian Post in its name.

4. Miranda House, New Delhi

4. Miranda House, New Delhi Fourth on the list is Miranda House, New Delhi which was on the eighth position last year.

A residential college for women, Miranda House is also regarded as one of the premier women's institutions of Delhi University.
It was founded in 1948 by the then Vice-Chancellor Sir Maurice Gwyer with a student strength of 33.

Today, the college offers undergraduate and post graduate courses across 16 academic departments in liberal arts and science to more than 2,500 students.

The college building which was designed by renowned architect Walter Sykes George was recently declared as a heritage building.

5. Fergusson College, Pune

5. Fergusson College, Pune Sharing the fifth spot this year is Fergusson College, Pune
 
The college got its name on January 2, 1885, to acknowledge the efforts of Sir James Fergusson, the first patron of the Deccan Education Society who strived towards the formation of the college. The college was inaugurated by William Wordsworth, the grandson of the famous English poet.

The Most Unforgettable Space Shuttle Pictures

When the space shuttle Atlantis lands on Thursday, it will wrap up STS-135, the final shuttle mission in the U.S. program's 30-year history.

Even with the tragic losses of Challenger and Columbia, the space shuttle has become an icon among U.S. science and technology achievements. During the past three decades, shuttles carried the first U.S. woman and the first African American into space, deployed famous satellites such as the Hubble Space Telescope, and delivered valuable parts and supplies to the International Space Station (ISS).

"The space shuttle has been with us at the heart and soul of the human spaceflight program for about 30 years, and it's a little sad to see it go away," STS-135 mission commander Christopher Ferguson recently told reporters in a televised interview from the ISS.

"It's going to be an emotional moment for a lot of people that dedicated their lives to the shuttle program for 30 years. But we're going to try to keep it upbeat ... We're going to try to make it a celebration of the tremendous crowning achievements that have occurred."

Scientists found new molecule that may lead to better drug for TB

Transitmycin was extracted from marine microorganism isolated from soil sample

Scientists at the Tuberculosis Research Centre (TRC) here have hit upon a new molecule with anti-bacterial and anti-viral properties that could potentially lead to a better drug for the treatment of TB and common HIV sub-types.

The team at TRC extracted the molecule, Transitmycin, from the marine microorganism Streptomyces sp. isolated from a soil sample off the Rameswaram coral reef.

The brominated and pigmented (yellow) antibiotic was found effective during in vitro tests against dormant and active forms of Mycobacterium tuberculosis — the pathogen that triggers one of the leading infectious diseases worldwide.

Another capability

The Transitmycin molecule also exhibited promising inhibiting capability against certain common HIV sub types such as clade B and C (HIV clade C is the most common HIV strain in India) and pathogens such as E. Coli and Staphylococcus aureus.

“The significance of the discovery of this molecule is that it comes at a time when there is very little to offer to patients developing multi-drug resistance to otherwise effective drugs in the regimen like Rifampicin and isoniazid,” said Vanaja Kumar, Head of Bacteriology at TRC, Chennai.

The combined resistance to Rifampicin and isoniazid has an adverse impact on the TB control programme. Compounding matters is the emergence of extensively drug resistant tuberculosis (XDR) involving resistance to fluoroquinolone and one of the three second-line injectibles (capreomycin, kanamycin or amikacin).

Simultaneous treatment

“Equally significantly, the molecule's dual anti-bacterial and anti-viral action could lead to a drug that could simultaneously treat patients co-infected with TB-HIV,” she said. Conventionally, Rifampicin (TB) and Nevirapine (HIV) cannot be used simultaneously.

“Given the antibiotic efficiency of the basic molecule, further refinement of the compound could improve potency by 10 to 20 times,” said Mukesh Doble, Professor, Department of Biotechnology, IIT-Madras.

Along with IIT-M, Periyar University, Salem also collaborated in the Rs.20-lakh project funded by the Department of Science and Technology.

Simple structure

Among all the compounds under testing, Transitmycin proved to be the best by virtue of its simple structure, status as a polar and water-soluble compound and minimal cyto toxicity, said Luke Elizabeth Hanna, TRC scientist.

However, despite all the promise at the laboratory-level, a Transitmycin drug could be far away — at least ten years — when it is put through the acid tests of animal trials and clinical trials. The project would also require funds to the tune of around Rs.300 crore from here on.

After filing for a patent in February, the scientists have also sent a 64-page proposal to the ICMR to push the case for funded research to take the project forward.

Animal trials

R. Balagurunathan, co-investigator and head of Microbiology, Periyar University, hoped that animal trials could soon be launched as the Indian Council of Medical Research had agreed to provide linkages with ICMR institutions with animal houses.

Scientists pointed out that while actinomycetes are the most valuable microorganisms capable of producing chemically diverse metabolites with wide-ranging biological applications, the rate of discovering new compounds from terrestrial actinomycetes has decreased in the recent past.

Transitmycin belongs to the family of marine actinomycetes that are becoming the promising source for secondary metabolites. And, if it paves the way for a drug, Transitmycin holds the advantage of having its coral reef origins sterilised from human interference — this extends the time cycle of humans developing resistance to a drug derived from this molecule.
