Mysuru, Mar 18: Even though the migration season is coming to end and the winged visitors are set to fly back, the water bodies where most birds nest and breed are under close surveillance with the report about spread of bird flu in Mysuru as unusual death of birds can be a cause for worry and hence the authorities are on high alert.

At Karanji Lake, the birds are watched in detail twice – morning and evening. If any sick bird or dead bird is noticed, the Zoo Vets are alerted. So far, no such birds had been sighted. The surveillance data is maintained every day. Intensive surveillance and passive surveillance is done.

Zoo Authority of Karnataka (ZAK) Member Secretary B P Ravi said the birds are doing well and there is no cause for worry with their health monitored constantly along with tests on the bird droppings done every month at the National Institute of High-Security Animal Diseases in Bhopal.

Bengaluru, Feb 24: Fugitive underworld don Ravi Poojary, with more than 90 criminal charges pending against him, was brought to the city in the wee hours of Monday after he was arrested from Senegal in South Africa.

Police said that he was wanted in more than 92 criminal cases. In Bengaluru alone, he was involved in more than 39 cases, including double murder of Ravi and Shobana in 2007, an attempt to murder attack on Mantri developers 2009, extortion and other crimes etc. He had committed crimes in various parts of the state including Myusuru, Hubballi, he had involved in extortion, threatening builders, politicians, etc.

"Though Senegal police had nabbed him about six months back to get him to India it took more than six months since there was no agreement to deport criminals from that state to us. However, now all legal hurdles have been removed and we have succeeded in bringing him", a top police official told media.

A team of Bengaluru Police headed by Additional Director General of Police Amar Kumar Pandey, Joint Police Commissioner Sandeep Patil reached Senegal on Saturday and brought him to the city by Air France flight.

Ravi Poojari was wanted in cases of extortion and murder and was active in the Mumbai underworld. He was part of the underworld don Dawood Ibrahim's gang and later is said to have worked with 'Chota Rajan' for some time. Claiming to be an enemy of Dawood, Poojari reportedly finished off all his associates and anti-India elements in the country. His men were involved in a shootout on the Shabanam Developers office in Bengaluru in which a woman staffer was killed.

He is also said have been involved in the shootout case of Shahid Azmi, an advocate from Mumbai. There are cases against him in Kerala, Gujarat, and Maharashtra.

Washington D.C., May 8: The prime time for brain development in a child's life is the first year, where the infant spends most of the time asleep. It is the time when neural connections form and sensory memories are encoded.

However, when sleep is disrupted, as occurs more often among children with autism, brain development may be affected, too.

New research led by the University of Washington finds that sleep problems in a baby's first 12 months may not only precede an autism diagnosis but also may be associated with altered growth trajectory in a key part of the brain, the hippocampus.

The study, which was published in the American Journal of Psychiatry, researchers report that in a sample of more than 400 taken of 6- to 12-month-old infants, those who were later diagnosed with autism were more likely to have had difficulty falling asleep.

It also states that this sleep difficulty was associated with altered growth trajectories in the hippocampus.

"The hippocampus is critical for learning and memory, and changes in the size of the hippocampus have been associated with poor sleep in adults and older children.

As many as 80 per cent of the children with autism spectrum disorder have sleep problems," said Annette Estes, director of the UW Autism Center and senior author of the study.

"In our clinical experience, parents have a lot of concerns about their children's sleep, and in our work on early autism intervention, we observed that sleep problems were holding children and families back," added Estes, who is also a UW professor of speech and hearing sciences.

"It could be that altered sleep is part-and-parcel of autism for some children. One clue is that behavioural interventions to improve sleep don't work for all children with autism, even when their parents are doing everything just right. This suggests that there may be a biological component to sleep problems for some children with autism," said Estes.

To consider links among sleep, brain development, and autism, researchers at the IBIS Network looked at MRI scans of 432 infants, surveyed parents about sleep patterns, and measured cognitive functioning using a standardized assessment.

At the outset of the study, infants were classified according to their risk for developing autism: Those who were at higher risk of developing autism -- about two-thirds of the study sample -- had an older sibling who had already been diagnosed.

Infant siblings of children with autism have a 20 per cent chance of developing autism spectrum disorder -- a much higher risk than children in the general population.

In the current study, 127 of the 432 infants were identified as "low risk" at the time the MRI scans were taken because they had no family history of autism.

They later evaluated all the participants at 24 months of age to determine whether they had developed autism. Of the roughly 300 children originally considered "high familial risk," 71 were diagnosed with autism spectrum disorder at that age.

Problems with sleep were more common among the infants later diagnosed with an autism spectrum disorder, as were larger hippocampi. No other subcortical brain structures were affected, including the amygdala, which is responsible for certain emotions and aspects of memory, or the thalamus, a signal transmitter from the spinal cord to the cerebral cortex.

The authors note that while parents reported more sleep difficulties among infants who developed autism compared to those who did not, the differences were very subtle and only observed when looking at group averages across hundreds of infants.

Sleep patterns in the first years of life change rapidly as infants transition from sleeping around the clock to a more adult-like sleep/wake cycle. Until further research is completed, Estes said, it is not possible to interpret challenges with sleep as an early sign of increased risk for autism.
