Bengaluru, Jun 16: Karnataka Pradesh Congress Committee (KPCC) chief DK Shivakumar's daughter Aishwarya and Cafe Coffe Day founder late VG Siddhartha's son, Amarthya Hegde got engaged at SM Krishna Residence, Sadashivanagar in Bengaluru on Monday.
Only family members were present in the event. Amarthya Hegde is also the grandson of former Union Minister SM Krishna.
Last year in July, the body of Cafe Coffee Day (CCD) founder Siddhartha was unearthed on the banks of Netravati river.

Mangaluru, Feb 18: Within days after Kambala racer Srinivasa Gowda emerged a national hero, another Kambala racer Nishant Shetty has grabbed headlines. 

Nishant Shetty from Bajagoli Jogibettu reportedly broke Gowda’s record at the Venoor Kambala on Sunday. Shetty recorded 143m in 13.68 seconds. If calculated for 100m he clocks it in 9.51 seconds. His speed is faster than Gowda who clocked 9.55 seconds.

According to Kambala organisers, with Shetty’s feat, four participants have joined the elite club of racers who have completed the 100 metres in less than ten seconds.

They are Iruvathur Anand (9.57 secs), Akkeri Suresh Shetty (9.57 secs), Srinivas Gowda (9.55 secs) and Nishant Shetty (9.51 secs). Anand and Suresh Shetty had participated in the same Venoor Kambala where Nishant emerged first.

Kambala is an annual race held in Karnataka where people sprint 143m through paddy fields with the buffaloes. During the race, the racers try to bring the buffaloes under control by holding their reins tight and beating them, making it amply clear that the animal plays an equally important role in achieving the timing. Traditionally, it is sponsored by local Tuluva landlords and households in the coastal districts of Dakshina Kannada and Udupi.

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.
