We will blast store: Karachi Bakery’s Bengaluru outlet receives threat over name row

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 8: 15 police personnel from Bangalore's Whitefield division tested positive for COVID-19 on Wednesday.

Out of these, 12 are from the Hindustan Aeronautics Limited (HAL) police station, sources said.

A total of 27 police staff of the Whitefield division have tested positive so far and five have been discharged. The HAL police station closed on June 27 after one police staff tested COVID positive. All personnel of the police station were tested in the following days and 12 tests returned positive.

Istanbul: Mosques in Turkey reopened on Friday for mass prayers after more than two months as the government further eased strict restrictions to stop the spread of the new coronavirus.

Turkey has been shifting since May to a "new normal" by easing lockdown measures and opening shopping malls, barbershops and hair salons.

President Recep Tayyip Erdogan has said many other sites -- restaurants and cafes as well as libraries, parks and beaches -- will reopen from Monday.

Hundreds of worshippers wearing protective masks performed mass prayers outside Istanbul's historic Blue Mosque for the first time since mosques were shut down in March.

In the Ottoman-era Fatih mosque, worshippers prayed both inside and outside, with the municipality handing out disinfectants and disposable carpets.

"I have waited a lot for this, I have prayed a lot. I can say it's like a new birth, thanks to God, he has brought us back here," he said.

Another worshipper, Asum Tekif, 50, said: "It has a been a long time... we missed the mosques."

Turkey, a country of 83 million, has so far recorded 4,489 coronavirus-related deaths and 162,120 confirmed cases.

Prayers in Hagia Sophia

Muslim clerics on Friday recited prayers in the Hagia Sophia, the world famous Istanbul landmark which is now a museum after serving as a church and a mosque.

The prayers were held to celebrate the anniversary of the conquest of Constantinople, today's Istanbul, by the Ottomans in 1453.

"It is very important to commemorate the 567th anniversary of the conquest ... through prayers in the Hagia Sophia," said President Recep Tayyip Erdogan, who attended the ceremony via videoconference.

The stunning edifice was first built as a church in the sixth century under the Byzantine Empire as the centrepiece of its capital Constantinople.

After the Ottoman conquest, it was converted into a mosque before being turned into a museum during the rule of Mustafa Kemal Ataturk, the founder of modern Turkey, in the 1930s.

But there have been hints about reconverting the Hagia Sophia into a mosque. Last year, Erdogan himself mooted the possibility of turning Hagia Sofia museum into a mosque.

Such calls have sparked anger among Christians and raised tensions with neighbouring Greece.

In 2015, a Muslim cleric recited the Koran in the Hagia Sophia for the first time in 85 years to mark the opening of an exhibition.

After Friday prayers at the Blue Mosque, a small group of Muslim worshippers shouted: "Let the chains break and let the Hagia Sophia open".

The group was later dispersed by the police who stopped them from protesting near Hagia Sophia that sits immediately opposite the Blue Mosque.
