BJP will be responsible for any untoward incident during Tipu Jayanti: Karnataka govt

Mangaluru, May 25: D V Sadananda Gowda, Union Minister for Chemical and Fertilizer, has once again written to the Ministry of External Affairs urging to take steps to operate more repatriation flights from Gulf countries to Karnataka. 

In his second letter in 10 days addressed to Subrahmanyam Jaishankar, Union Minister for External Affairs, expressed regret over not giving due priority for the repatriation of Kannadigas in the middle east during the extended second phase of Vande Bharat Mission. 

"I shall be grateful if you could personally intervene and instuct the concerned in arranging flights to Mangaluru and Bengaluru from Gulf countries in existing schedule itself," Mr Gowda urged Mr Jayashankar. 

Bengaluru, Jul 1: Karnataka Primary and Secondary Education Minister S Suresh Kumar on Wednesday played down reports about confusion regarding valuation of Second Pre- University and the Secondary School Leaving Certificate exam papers.

"Creating confusion has become a habit. There was confusion before the exam, during the exam and now confusion about the valuation of the exam papers," Kumar told reporters in Ramanagara when asked about the confusion over the valuation of answer sheets.

He had gone there to inspect a few centres where the SSLC or the 10th standard exams are underway.

The minister reminded people not to speak about the abilities of the students with contempt.

"Our students have toiled hard and are enthusiastically appearing for the examination. They are eligible for the marks they will score. So we should not speak about our children with disrespect," Kumar said.

The Education Minister said he had spoken to many leaders including former chief ministers Siddaramaiah and H D Kumaraswamy on conducting the examinations.

"Kumaraswamy had insisted on postponing the examination. I personally spoke to him and apprised him about the steps taken by us. I told him that we will work with more sincerity to ensure the safety of the children," Kumar said.

The SSLC exam was scheduled to take place from March 27 but due to the coronavirus-induced lockdown, it was postponed.

While the CBSE and a few other states either decided to give marks based on the students' performance in the previous examinations such as quarterly and half-yearly exams or gave general promotion to the students, Karnataka went ahead to hold the exam.

According to Karnataka Secondary Education Examination Board officials, around 8.5 lakh students have enrolled this year for the SSLC examination.

The exams are being held at 2,879 exam centres across the state.

Prior to the SSLC examination, the last exam of the Second PUC was also conducted on June 18, which was also put on hold due to the lockdown.

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.
