Houston, Jul 29: Artificial light emitted from digital devices such smartphones and tablets could reduce the quality of your sleep, a study has warned.

The largest source of blue light is sunlight, but it is also found in most LED-based devices. Blue light boosts alertness and regulates our internal body clock, or circadian rhythm, that tells our bodies when to sleep.

This artificial light activates photoreceptors called intrinsically photosensitive retinal ganglion cells (ipRGCs), which suppresses melatonin, the hormone that signals your body that it is time to sleep.

"The most important takeaway is that blue light at night time really does decrease sleep quality. Sleep is very important for the regeneration of many functions in our body," said Lisa Ostrin, assistant professor at University of Houston in the US.

In the study, participants, aged between 17 and 42, wore short wavelength-blocking glasses three hours before bedtime for two weeks, while still performing their nightly digital routine.

Results showed about a 58 per cent increase in their night time melatonin levels.

"Those levels are even higher than increases from over- the-counter melatonin supplements," said Ostrin, who led the study published in Ophthalmic & Physiological Optics.

Wearing activity and sleep monitors 24 hours a day, the 22 study participants also reported sleeping better, falling asleep faster, and even increased their sleep duration by 24 minutes a night, according to Ostrin.

Ostrin recommends limiting screen time, applying screen filters, wearing computer glasses that block blue light, or use anti-reflective lenses to offset the effects of artificial light at nighttime.

Some devices even include night mode settings that limit blue light exposure.

"By using blue blocking glasses we are decreasing input to the photoreceptors, so we can improve sleep and still continue to use our devices.

That is nice, because we can still be productive at night," Ostrin added.

Jeddah, May 1: The government of India and its diplomatic missions in the Gulf Cooperation Council (GCC) States have begun elaborate preparations for the massive evacuation of their nationals stranded or needing to return once the lockdown travel restrictions are lifted.

The Indian missions in Saudi Arabia, the United Arab Emirates (UAE), Kuwait, Bahrain, Oman and Qatar have started registration for the return of their nationals. The move coincides with the directive of New Delhi to the Indian Air Force and Navy to get their big engines ready to bring back citizens stuck in the GCC states.

India’s External Affairs Minister S. Jaishankar has stated that the Indian missions in the GCC states have been liaising with local authorities for repatriation of Indians. More than eight millions Indians work and live in the Gulf countries.

The Indian Embassy in Saudi Arabia said that it has issued directives to their nationals who seek repatriation to India to fill an application form so as to facilitate their travel when the authorities lift the travel restrictions. Similar advisories have also been issued by the embassies in other Gulf States.

The Riyadh Embassy said in a press statement that the purpose is only to collect data and no decision has been taken yet regarding resumption of flights to India.

The Embassy will make an announcement with regard to repatriation of Indian nationals when the government of India takes a decision in this regard, the statement said, adding that separate forms have to be filled for each individual, including Indian worker or his or her family members.

The Embassy is in the process of working out the modalities of evacuation of stranded Indians in line with the directions of the government of India, the statement pointed out.

The Embassy and the Consulate General in Jeddah are closely monitoring the situation and are taking all the required measures to ensure the welfare of Indian citizens.

The missions have taken all the necessary measures for the supply of food, medicines and other emergency assistance to Indians in need and that is in coordination and cooperation with volunteers of major community organizations across the Kingdom.

These initiatives have been accelerated following the interactions of Ambassador Dr. Ausaf Sayeed with community volunteers and social workers from all parts of the Kingdom. The Embassy has also been in touch with all major companies in the Kingdom that employed Indian workers to carry out regular monitoring of the workers’ health, especially in labor camps, and take all other precautionary and preventive measures to ensure their health and safety.

According to the plan drawn up by the government of India, the first commercial flights from the Gulf could start after May 3, if the nationwide lockdown restrictions are not extended.

INS Jalashwa, an amphibious assault ship, and two Magar class tank-landing ships are being readied for the evacuation purposes, India’s IANS reported.

These ships, which have a total capacity of 2,000 people, have started making arrangements as per the standard protocols laid out to deal with suspected coronavirus cases like social distancing and sanitization.

The Indian Air Force has been evacuating citizens from coronavirus hit countries such as China, Japan, Iran, Italy and Kuwait since January. The force has stated that it has kept C-17 Globemaster and C-130s on standby which can be used whenever they are required.

Apart from them, Air India flights are also being kept on standby to pick up stranded Indians from the GCC countries.

15 Indian fatalities in western region

Speaking to Saudi Gazette, Indian Consul General Mohammed Noor Rahman Sheikh said that as of Thursday a total of 15 Indian coronavirus fatalities were reported in the western region.

These included seven cases in Makkah, six in Madinah and two in Jeddah. Around 140 Indians have tested positive in the region where most of the coronavirus cases in the Kingdom have been reported.

He said that permission was not accorded from the Ministry of Haj and Umrah to use the Indian Haj mission facility in Makkah as the center to assist the community members with regard to the coronavirus related cases.

“Our medical in charge is in Makkah and with the support of some other staffers, he has been actively involved in lending a helping hand to those Indian nationals who are in distress,” he said.

“We are in regular contact with the Ministry of Health officials in ensuring quick medical assistance to those who are tested positive.” He said preparations are under way for repatriation of Indians once permission is ready to take them home. “We are maintaining a database of all those who contacted the consulate with a request for their repatriation,” he added.

Meanwhile, the bodies of two Indians from the southern state of Kerala who succumbed to the pandemic were buried in Makkah. Naletil Muhammad from Ancharakkandi of Kannoor district, a restaurant worker in Makkah, gave samples at King Faisal Hospital a few days ago after developing symptoms of the disease.

When the hospital authorities advised him to remain in medical isolation, he reportedly preferred to remain in isolation at his residence where he succumbed to the pandemic after a few days.

Muhammad’s two sons, who are working in Riyadh, alerted his colleagues when they failed to contact him over phone. They found him dead at his residence on Monday. Eventually, Ministry of Health officials sent all his six colleagues to medical isolation.

Kottuwala Ippu Musliyar from Thennala, Vengara in Malappuram district, was a well-known social worker in Makkah. He died of coronavirus at Hira Hospital on Wednesday after undergoing treatment for a couple of days.

Mujeeb Pukkottoor, a prominent Indian social worker and general secretary of Makkah chapter of Kerala Muslim Cultural Center, was authorized by their spouses to carry out their burial procedures.

Accordingly Muhammad was buried on Wednesday and Ippu Musliyar on Thursday at the designated area for the coronavirus deceased persons at Sharaie Cemetery in Makkah.

New Delhi, Jan 30: Tension spiralled in Jamia Nagar on Thursday after a man fired a pistol at a group of anti-CAA protesters, injuring a Jamia Millia Islamia student before walking away while waving the firearm above his head and shouting "Yeh lo aazadi" amid heavy police presence in the area.

Massive protests erupted in the area after the incident with hundreds of agitated people gathering near the university, breaking barricades and clashing with police personnel.

The man, who identified himself as "Rambhakt Gopal", was subsequently overpowered by police and detained. He was taken into custody and was being interrogated, police said.

The entire drama, which triggered panic in the area, was captured by television cameras that showed the man in light coloured pants and a dark jacket, walking away on an empty road barricaded by police, turning around and shouting at the protesters in Hindi, "Here, take this freedom."

The gunman went live on Facebook before the brandishing the gun. Police said they were verifying whether it is his real name.

Before the attack, the man also put out messages on Facebook stating "Shaheen Bhag Khel Khatam" (Run Shaheen, the game is over). Another message stated, "Please wrap me in saffron in my last journey with slogans of Jai Shri Ram". His Facebook profile was deleted after screenshots of his posts were circulated widely on social media platforms.

Several students recapped how their peaceful march on Gandhi's death anniversary became violent.

"We were moving towards the Holy Family Hospital where the police had raised barricades. Suddenly, a gun-wielding man came out and opened fire. One bullet hit my friend's hand," Aamna Asif, a student of economics at the university, told PTI.

She said her friend, Shadab Farooq, a mass communication student, was trying to calm the attacker but he shot at him injuring his left hand.

Farooq, who belongs to Kashmir, was taken to the AIIMS Trauma Centre.

Ragibh Naushad, an LLB student at the university, said, "The Jamia Coordination Committee organised a march to pay homage to Gandhi ji on his death anniversary. It started at 12 noon from Gate number 7, but police denied the permission and stopped the march near the Holy Family hospital.

"A man named Gopal, came there and started brandishing a weapon and later shot a round. He was also chanting pro-CAA slogans."

The incident led to panic in the area.

Khalid Hassan, a JMI alumnus, said initially many were not sure whether it was a gunshot or a tyre burst.

There was heavy police and media presence when the incident took place.

The students were heading from Jamia to Mahatma Gandhi's memorial Rajghat. The march was stopped at the Holy Family Hospital near the university.

Chinmoy Biswal, DCP (southeast), said the students wanted to take out a march from Jamia to Rajghat but were denied permission.

"They were being repeatedly told that the protest should be carried out peacefully. We had barricaded the road just before the Holy Family hospital. Meanwhile, a person was seen in the crowd who waved something which appeared to be a weapon."

"We have detained him and are interrogating him. One person has also been injured," Biswal said.

High-protein diets may help people lose weight and build muscle, but there is a downside to it --a greater heart attack risk. Researchers now report that high-protein diets boost artery-clogging plaque.

The research in mice showed that high-protein diets spur unstable plaque -- the kind most prone to rupturing and causing blocked arteries.

More plaque buildup in the arteries, particularly if it's unstable, increases the risk of heart attack.

"There are clear weight-loss benefits to high-protein diets, which has boosted their popularity in recent years," said senior author Babak Razani, associate professor at Washington University School of Medicine in St. Louis, Missouri.

"But animal studies and some large epidemiological studies in people have linked high dietary protein to cardiovascular problems. We decided to take a look at whether there is truly a causal link between high dietary protein and poorer cardiovascular health," Razani added.

The researchers studied mice who were fed a high-fat diet to deliberately induce atherosclerosis, or plaque buildup in the arteries.

Some of the mice received a high-fat diet that was also high in protein. And others were fed a high-fat, low-protein diet for comparison.

The mice on the high-fat, high-protein diet developed worse atherosclerosis -- about 30 per cent more plaque in the arteries -- than mice on the high-fat, normal-protein diet, despite the fact that the mice eating more protein did not gain weight, unlike the mice on the high-fat, normal-protein diet.

"A couple of a scoop of protein powder in a milkshake or smoothie adds something like 40 grams of protein -- almost equivalent to the daily recommended intake," Razani said.

"To see if protein has an effect on cardiovascular health, we tripled the amount of protein that the mice receive in the high-fat, high-protein diet -- keeping the fat constant. Protein went from 15 per cent to 46 per cent of calories for these mice".

Plaque contains a mix of fat, cholesterol, calcium deposits and dead cells. Past work by Razani's team and other groups has shown that immune cells called macrophages work to clean up plaque in the arteries.

But the environment inside plaque can overwhelm these cells, and when such cells die, they make the problem worse, contributing to plaque buildup and increasing plaque complexity.

"In mice on the high-protein diet, their plaques were a macrophage graveyard," Razani informed.

To understand how high dietary protein might increase plaque complexity, Razani and his colleagues also studied the path protein takes after it has been digested -- broken down into its original building blocks, called amino acids.

"This study is not the first to show a telltale increase in plaque with high-protein diets, but it offers a deeper understanding of the impact of high protein with the detailed analysis of the plaques," said Razani.

"This work not only defines the critical processes underlying the cardiovascular risks of dietary protein but also lays the groundwork for targeting these pathways in treating heart disease," he added.
