Kamaladevi participated in the freedom movement

On Tuesday, Google celebrated the 115th birth anniversary of the multi-faceted freedom fighter, activist and promoter of the arts, Kamaladevi Chattopadhyay, with a doodle.

Kamaladevi, who bagged the Padma Vibhushan in 1987 (a year before her death), was a woman of many firsts. She was an active participant in the freedom movement, championed women’s rights, founded the All-India Womens Conference (AIWC), led the renaissance of Indian handicrafts and handlooms, and worked for the development of the performing arts in India.

Born in Mangalore in 1903, Kamaladevi was widowed at 16. She married Harindranath Chattopadhyay when she was 20 and then headed to London where she graduated with a diploma in Sociology. She joined the freedom movement when she returned to India and she eventually became the first woman to run for a legislative seat in India, when she ran for the Madras Provincial Legislative Assembly.

She then founded the AIWC, which did a lot of work for social reform. She was credited for persuading Mahatma Gandhi to encourage more women to march with him during the freedom struggle. In 1930, Kamaladevi was part of Gandhi’s salt satyagraha team and she was later arrested for entering the Bombay Stock Exchange to sell packets of contraband salt.

Post independence, she worked for the rehabilitation of refugees. She then dedicated her life to the promotion of Indian indigenous arts and crafts and theatre. Thanks to her work behind the scenes, several renowned institutions, including the National School of Drama, Central Cottage Industries Emporium, and the Crafts Council of India, came into existence. She later headed the Sangeet Natak Akademi and in 1974 was awarded the Sangeet Natak Akademi Fellowship.

The doodle, created by Finland-based artist Parvati Pillai, salutes Kamaladevi’s contribution to the creative fields. It depicts the various fields she promoted, including the sitar, sarangi, Karthak dance, embroidery and basket weaving.

It is strange that the city of Bengaluru which we all accept today as a single city was not a single city at all until recently. Before Bengaluru was welded into a single city under a common corporation in 1949, it existed as a twin city. There were two portions to the city. The civil and the military portions were separate entities with a separate municipality and a separate collector. The job of the collector was to look after the revenue and the law and order problems of the city. He was functioning under the Resident. The Collector was also the Municipal President. The Bangalore city agglomeration had a population of 29,21,751 and the corporation area had a population of 24,76,355 in 1981. The city’s population recorded a growth of over 70% between 1971 and 1981.

The site of the present city had many prehistoric settlements. Neolithic tools have been located at the race course and Jalahalli. Byrasandra was also a prehistoric site. Dr Shikaripura Ranganatha Rao, an eminent archaeologist feels that the attractive site of the bugle rock at Basavangudi could have been a prehistoric habitat. Roman coins have been unearthed at Yeshwantpur and Jalahalli.

The name Bangalore is as old as the ninth century and the name is found in a Kannada inscription found near the Begur temple. A long record of circa 890 AD and the name appears to have a floral origin, derived from the tree Benga (Venga or Pterocarpus marsupium or the Indian Kino).

The explanation that the name was derived from Benda kala ooru, or the village of boiled beans as described by the Hoysala King Ballala when he was hungry during his visit to the place (when he was hunting) becomes irrelevant as the above name was much older that King Ballala of the Hoysala dynasty. Benda kala ooru or the place full of granite rocks is another explanation to a place name but granite is neither Bangalore’s exclusive speciality nor the old form, thousand years, found in the record indicates the place name being anyway connected to Benachu kallu. The place mentioned as Bengaluru in the Ganga record is originally a hamlet, even now called as Hale Bengaluru near Kodigehalli, not far away from Hebbal. It is said that Kempe Gowda I when he built the new capital town in 1537 called it Bangalore as his mother and wife belonged to the hamlet Bangalore, now Hale Bengaluru. In literary works, Bangalore is also called Kalyana Nagare or the ‘City Auspicious’. Though the fort built by Kempe Gowda then has totally vanished, the spots like the Yelahanka Bagalu (Mysore Bank Square) and Halsur Bagalu still exist. Halsur Bagalu or gate, now a police station is named after it. The gate proper even now remains hidden. The old remains of the ramparts and the moats were completely demolished during the nineteenth century. The town was conquered by the Bijapur sultans in 1638 and Shaji Bhonsle secured the town and its surroundings as a Jagir in 1638. The testimony to 50 years of Maratha rule is in the form of an inscription of Ekoji, Shaji’s son near the Kadu Malleshwara temple. Bangalore was conquered by the Mughals in 1686. The mosque at Taramandalpet is a notable vestige of Mughal rule. The city was leased to the Mysore ruler, Chikkadeva Wodeyar by the Mughals in 1689 and Chikkadeva Wodeyar expanded the fort to the south and built the Venkatramana temple in this fort area. This new fort in granite was strengthened by Haider Ali who secured Bangalore as a Jagir in1759. The British conquered the city in 1799 after defeating Tipu Sultan.

The original Bangalore city was clustered around the fort and city market and covered the area until the present Mysore bank square. Today, there is a bus stop at the place where the Dharmabudi tank existed earlier. The old city had areas like Cottonpet, Sunkalpet, Kumbharpet and the Balepet areas. The medieval character of the city’s old settlements typical of any old village is indicated by the names of these areas.

Every community or professional caste had its own street or streets in every village or town of ancient times. Sigebeli is the settlements of Brahmins, reminiscent of old Agrahara or Brahmapuri. Kempapura Agrahara was another settlement of the Brahmins created by Kempe Gowda II towards the Magadi road area beyond the Brahmabudi tank. Parts of Gandhi Nagar area appear to have been reclaimed from the Dharmabudi tank during the early part of the nineteenth century.

The Cantonment area grew as a separate township after the British shifted their troops to the place in 1806 and the first camp was located at the present Air Force Hospital in 1808. The present cantonment also consists of many old villages like Halasur, Blackpally, Doddakunte and Akkithimmanahalli. It was no part of the old Bangalore pettahs. At Domlur on the periphery of the old cantonment, the Chokkanatha temple built by the Cholas still remains. At Blackpally or Shivaji Nagar, there existed a Catholic church which later took some shape of the 18th century and now its is the St Marys Basilica. The cantonment area also saw the construction of some of the beautiful buildings of the European Renaissance style. Both churches and secular buildings which were mostly government offices during the 19th century.

New extensions were added to the town in Chamrajpet and Seshadripuram. Chamrajpet was named after Chamraja Wodeyar in 1892, the latter named after Dewan Seshadri Iyer. The visit of a plague in 1898 caused the creation of two bigger extensions in 1898. These were Basavangudi named after Basaveshwara temple or the Bull Temple in Sukenahalli village and Malleshwaram named after the Kadu Malleshwara temple in old Mallapura village. The area in both the places was full of fields.

The next time you think of Bengaluru as the city of Bengaluru, you would do well to remember its origins. There are several people alive today who remember the two distinct facets to the city; the pettahs and the cantonment. These portions were welded and expanded to make the beautiful city we live in.

Genetic diversity can prevent rapid spread of infectious diseases

Choice of pandemic: The models are best suited to study airborne diseases such as H1N1, say Nagasuma Chandra (left) and Narmada Sambataru.

The team studied how susceptibility sub-populations affect the spread of the disease

An infectious disease can spread at different rates in different countries. This phenomenon has been observed in many cases, for instance in the 2009 H1N1 influenza pandemic. An International group of researchers including those at Indian Institute of Science (IISc), Bengaluru, and The Institute of Mathematical Sciences (IMSc), Chennai, looks at genetics as a way to explain this phenomenon. They find that the greater the genetic diversity in immune response, the stronger is the barrier to the spread of the disease. The results have recently been published in PLOS Computational Biology.

Nagasuma Chandra’s team at IISc chose to study H1N1 as modelling it had some advantages.

“There is a lot of work on H1N1 and a lot of data including clinical and epidemiological. These models are also best suited to study airborne diseases. As H1N1 spreads through air, choosing it made a lot of sense,” says Dr. Chandra.

Pandemic H1N1 virus

The pandemic H1N1 2009 influenza A virus was different from other influenza viruses encountered until then. According to the WHO, this is because it originated from animal influenza viruses and is unrelated to the human seasonal H1N1 viruses that have been in circulation among people formany years In fact, this virus is thought to have arisen from a mixture of two viruses: a North American virus that jumped from birds to swine and humans and a Eurasian swine virus that had circulated in pigs for about a decade before entering humans. Clinically also the virus’s effect was very different from that of other flu viruses in that younger people were more severely affected than older ones.

Narmada Sambataru and Sumanta Mukherjee who were at Dr Chandra’s lab, and Martin Lopez-Garcia from the University of Leeds, UK, spent nearly a year building up the model. Their research led them to establish how an individual’s genetic makeup can influence his or her susceptibility to the infection.

The immune system has both innate and adaptive response types to infections, in general. In the case of H1N1 infection, the adaptive immune system can recognise the presence of a virus within the cell and respond to it only if a molecule called the human leukocyte antigen (HLA) binds to some fragment of the viral protein (epitope) and ‘presents’ it to the environment outside the cell. Dr Chandra’s group has described the details of this aspect of H1N1 in an earlier paper published in the journal Clinical and Translational Immunology.

Immune response

“The main take-away from our work is that understanding how the immune response of different individuals leads to a spread of susceptibilities in a population is vital to figuring out how diseases spread,” says Gautam Menon of The Institute of Mathematical Sciences, a co-author of the paper. “This problem, of how to go from what we know about how individuals can vary in their susceptibility to understanding how epidemics spread across entire populations, has been identified recently as one of the major challenges in the study of epidemics.”

Having worked out how the genetic makeup of an individual can affect their susceptibility to the disease, the individuals can be grouped according to their susceptibility. Using a mathematical model called the SIR (Susceptible-Infected-Recovered) model, the researchers study how the presence of susceptibility sub-populations affect the spread of the disease. “In this model, individuals are initially susceptible but not infected.

“When an infection is introduced, individuals become infected at a rate determined by their estimated susceptibility to the pathogen, estimated using genetic information about the host as well as the pathogen. Infected individuals then proceed to recover,” says Dr Chandra.

Trends

The work captures the qualitative features of well-known trends of influenza spread in various parts of the world. “This work uses publicly available information about HLA class-I genes and their prevalence in populations around the world. Unfortunately, there is a significant shortage of this information for Indian populations,” she says.

The group is planning to propose a detailed study of this for Indian populations. “Once this information becomes available, we can do far more to predict disease spread in India. These predictions can be used to inform public policy and make better decisions. This is the real utility of such modeling methods, that we can explore different situations and ask what responses might be most effective in the context of specific diseases,” says Dr Menon.
