'Shivakumar eyeing Karnataka Congress president post'

Belagavi, Mar 10: Around 6,000 chickens were buried alive by some poultry farm owners here as the rate of flesh in the market dropped even below the cost price due to Coronavirus scare.

The poultry farm who buried the chickens on Monday evening belonged to Lolasuru village in Gokak Taluk of the district.

One of the owners, Nazir Makandar, said that there was no demand for chicken because of threat of Coronavirus.

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, Feb 2: The monthlong budget session beginning on Monday, which will mark BS Yediyurappa’s maiden budget in his fourth term as chief minister, is expected to be a fiery one.

The opposition JD(S) and Congress have already threatened to stall proceeding until BJP legislator Basangouda Patil Yatnal apologises for his controversial remarks against freedom fighter and centenarian HS Doreswamy. Yatnal had called him a fake and a Pakistani agent.

Disruptions are also likely to pose a threat to speaker Vishweshwar Hegde Kageri’s novel idea of having a two-day discussion on the Constitution of India to commemorate 70 years of the country’s Independence.

Both opposition parties have scheduled legislature party meetings early on Monday and they could coordinate on issues on the floor of the house to put the BJP — especially Yediyurappa — on the backfoot.

Yatnal is not known as a “hardliner”, but his attack on Doreswamy has garnered support from several ministers including CT Ravi, KS Eshwarappa and V Somanna. Yediyurappa may have a hard time defending his party’s line.

The BJP is yet to schedule its legislature party meeting, but MLAs suggest the party will allow the issue to be raised and debated in the legislature. “Both have expressed their point of view. Let there be a discussion on the matter, but not allowing the house to function will only be a waste of the state’s time and money,” said deputy chief minister CN Ashwath Narayan.

Besides the Doreswamy issue, Yediyurappa will also deliver his reply — postponed from February 20 — to the debate on the governor’s address. The issue of student Amulya Leona Narona’s arrest on a charge of sedition, the Bidar sedition case involving a parent of a school student, pro-Pakistan writings on walls in places in north Karnataka, introduction of NPR and the anti-CAA stir is also likely to feature during the lengthy session.
