I-Day lie exposed: Village mentioned by PM Modi still without power!

Mandya, Jul 24: Pressing for a total ban on stone mining and quarrying in and around the villages surrounding Krishna Raja Sagar Dam in the District, many organisations have called for Mandya bandh on July 29.

The bandh has been supported by Raitha Sangha, Karunada Sevakara Sanghatane, Auto Drivers Association, Jaya Karnataka, Bharatiya Samvidhana Hitharakshana Vedike, Sugarcane Growers Association, Vokkaligara Seva Trust and Dalita Sangarsh Samiti (Krishnappa faction).

The activists said that the State Government must immediately take steps and permanently ban mining in 20 km radius around KRS as continuous blasting for stones is causing grave danger to the structure.

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.

Thrissur, Feb 11: The latest test result of the woman medical student, who arrived here from China's Wuhan region and was the first positive case from India for the novel Coronavirus (nCoV), has come out negative, health officials said on Monday.

Her condition was "stable", they said.

According to the state health department as of now, 31 people are in isolation wards across various hospitals in the state.

"The blood test result of the first patient from Thrissur, from the National Institute of Virology (NIV) testing centre at Alappuzha, shows a negative result.

But we need confirmation from the NIV at Pune," a senior medical officer told news agency.

After the first positive case was reported from Thrissur, two other Keralite students from Wuhan, the epicentre of the virus, had tested positive in Alappuzha and Kasaragod districts.

The health department had earlier said those in isolation wards of various hospitals in the state have come down to 34.

"A total of 3,367 are under observation across the state, of which 3,336 are under home quarantine," a release issued by the health department said.

The department has already sent at least 364 samples for testing at the NIV at Pune and so far 337 results have returned negative.

The ''state calamity'' alert, which was declared on February 3, was withdrawn on Friday after no new positive cases of infection were detected.
