State's first butterfly park opens in Belvai

Bengaluru, Jan 26: BJP state president Nalin Kumar Kateel has been served with a court notice asking him to personally appear before the special court for people’s representatives on February 24, in connection with a defamation suit filed by Congress MLA Rizwan Arshad.

Rizwan had lodged the defamation suit against Kateel and state BJP social media chief after the party, in a tweet during the 2019 Lok Sabha election, alleged Rizwan’s involvement in the manufacture of fake voter identity cards.

Apart from Kateel, head of the party’s social media unit has also been asked to appear in person at the above court on February 24.

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.

Mangaluru, Feb 5: ‘Forum for the justice of December 19 Mangaluru firing victims’ has demanded that the policemen who are responsible for the death of two innocent men in Mangaluru one-and-a-half months ago should be booked for homicide. 

49-year-old Abdul Jaleel Kandak, a father of two, and 23-year-old Nausheen Kudroli, were killed in an arbitrary and unwarranted police firing during a disturbance occurred due to police baton charge in the city on December 2019. 

Addressing a press conference, Forum’s convenor Abdul Jaleel Krishnapur said that a judicial inquiry commission should be set up to probe into the police firing which claimed two lives and injured many other innocent civilians.  

“Already a murder case should have been filed against the policemen who opened fire on the people.  Instead, false cases have been booked against many innocent people including the victims. This is a blot on the society,” he said. 

He urged the government to direct the police department to drop false charges registered against the victims and take necessary action against the culprits in khaki. 

He said that the Form demands Rs 25 lakh each compensation for the kin of the two men murdered by the police and Rs 15 lakh compensation for those who injured in police firing on December 19.
