Drunk man hurls chocolate bomb' at Karnataka CM

Udupi, Jul 14: Abhijna Rao, a student of Vidyodaya PU College, Udupi, has emerged state topper in the science stream of II PUC. 

Abhijna has secured 596 marks in the II PUC examination-2020, the results of which were announced on Tuesday July 14. She scored a perfect 100 marks in Physics, Chemistry, Mathematics and Computer Science (PCMC). In Sanskrit and English she scored 100 and 96 marks respectively.

She had secured second position in the Karnataka SSLC examinations two years ago.

She is daughter of Asha Rao and Vittal Rao, a retired professor. Her sister Raksha Rao has completed Engineering from NITK Suratkal.

“After securing second rank in the state in SSLC, my target was to score more in PUC examinations. My parents and lecturers have supported me in my studies. All my teachers gave me proper guidance. Vidyodaya College also supported me. I was studying on a daily basis. The exams were easy and I had expected to score above 590. I am very happy to score 596," she said.

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.

Bengaluru, Jul 16: Aiming to forge a citizen-government partnership in combating the Covid pandemic, the Karnataka government is seeking plasma donations from survivors for a token appreciation of Rs 5,000, a minister said on Wednesday.

"I request all those who have recovered from Covid-19 to donate plasma and save lives. As a token of our appreciation, we will give Rs 5,000 to patients who come forward and donate their plasma," said Medical Education Minister K. Sudhakar.

He said the battle against the pandemic can only be won through citizen-government partnership.

On Wednesday, Covid cases swelled by 1,975 infections in Bengaluru, ground zero for the pandemic in the southern state, raising its total number of cases to 22,944, out of which 17,051 are active.

In the past 24 hours, the state as a whole registered a record 3,176 cases, raising Karnataka's tally to 47,253, even as 87 people succumbed to the virus.

Meanwhile, Sudhakar said 8,134 booth level workforce will conduct a house to house survey along with other Covid control measures in Bengaluru.

He said many locals and block level officers will be the members of the workforce.
