D DOWN THE WEEKLY LANE OWN THE WEEKLY LANE SUNDAY 6 JANUARY 4 CHENNAI SPORTS STATE NATION WORLD CITY BUSINESS JAI ANJANEYA SCIENCE TODAY HEALTH TODAY CT scans, commonly used in medical imaging, may increase the risk of brain tumours, a study has found. The use of computed tomography (CT) scans has increased dramati- cally over the last two decades. CT scans greatly improve diagnostic capabilities, which in turn im- prove clinical outcomes. However, they deliver higher radiation doses, and can especially affect children who are more susceptible to radiation-related malignancies than adults, re- searchers said. The most common malignancies caused by radioactivity among children and young adults are leukaemia and brain tumours. Researchers from Netherlands Cancer Institute evaluated leu- kaemia and brain tumour risks following exposure to radiation from CT scans in childhood. For a group of 1.68 lakh Dutch children who received one or more CT scans between 1979 and 2012, researchers obtained cancer inci- dence and vital status by record linkage. They surveyed all Dutch hospi- tal-based radiology departments to ascertain eligibility and partici- pation. In the Netherlands, paedi- atric CT scans are only performed in hospitals. Overall cancer incidence was 1.5 times higher than expected. For all brain tumours combined, and for malignant and nonmalig- nant brain tumours separately, dose-response relationships were observed with radiation dose to the brain. Relative risks increased to be- tween two and four for the highest dose category. The researchers observed no association for leu- kaemia. Radiation doses to the bone marrow, where leukaemia originates, were low. They caution that this pattern of excess cancer risk may be partly due to confounding by indication because the incidence of brain tumours was higher in the cohort than in the general population. CT scans are sometimes used to identify conditions associated with an increased tumour risk; the reason these children had CT scans may be associated with their risk of developing cancer. ‘Epidemiological studies of can- cer risks from low doses of medical radiation are challenging,’ said the study’s principal investigator, Michael Hauptmann, from Neth- erlands Cancer Institute. ‘Our careful evaluation of the data and evidence from other studies indicate that CT-related radiation exposure increases brain tumour risk,’ said Hauptmann. An international team of sci- entists will begin the New Year hunting for microbes and other living specimens in an unexplored lake far beneath the surface of the Antarctic ice sheet. Led by polar scientist John Pr- iscu of Montana State University in the US, a team of 45 scientists, drillers and support staff will drill 4,000 feet to the bottom of the ice sheet that covers Mercer Subglacial Lake about 370 miles from the South Pole. The lake, which measures nearly 62 square miles, was discovered more than a decade ago through satellite images but has never before been explored. The expedition, known as SAL- SA (Subglacial Antarctic Lakes Scientific Access), hopes to shed light on what kind of life can sur- vive in such remote regions and serve as an on-Earth comparison for habitats deep inside Mars or on the ice-covered moons of Jupiter and Saturn. While Mercer will be the second subglacial lake that humans have sampled directly, Fox wrote, it will be the first time scientists will use a remote vehicle to roam beneath the ice sheet, which leads the scientists to wonder if the submersible’s three video cameras might capture images of animals that live in the dark water. This is the second such expedi- tion for Priscu. In 2013, he and other MSU researchers published the discovery of microscopic life in Subglacial Lake Whillans in the journal Nature and received worldwide attention. Djokovic crashes out of Qatar Open Novak Djokovic lost surprisingly in Doha on Friday, beaten in the Qatar Open semi-final by world number 24, Roberto Bautista Agut, 6-3, 6-7 (8/6), 6-4. The Serb fell to his first defeat of the season in a high-quality contest lasting more than two-and-a-half hours, which saw the Spaniard lose his first set of the week but come back to beat the world number one. ‘What happened? I lost the match. That’s it,’ a clearly frustrated Djokovic said in his post-match press conference. Agut took Djokovic’s serve in the second game of the final set for the decisive break and secured victory on his first match point. ‘I will remember this match for [the rest] of my life’ said the 30-year-old Spaniard. He will play the Czech Republic’s Tomas Berdych in Saturday’s final. Sachin pays tribute to his coach Achrekar ‘Cricket in heaven will be enriched with the presence of (Ramakant) Achrekar sir,’ said iconic former batsman Sachin Tendulkar as he paid an emotional tribute to his childhood coach who passed away Wednesday. Achrekar, 87, died in Mumbai due to age- related ailments. ‘Like many of his students, I learnt my ABCD of cricket under Sir’s guidance,’ the Dronacharya awardee’s most famous ward said in a state- ment. ‘His contribution to my life cannot be captured in words. He built the foundation that I stand on,’ he added. Tendulkar, unarguably the greatest batsman in modern cricket, was coached by Achrekar at the Shivaji Park in Mumbai’s Dadar as a child. The iconic cricketer, who is now retired, has been quite vocal about Achrekar’s contribution in shaping him.

Responding to a special attention seeking motion brought by the opposition parties in the Assembly, Palaniswami said the government has alloted Rs 2,000 crore for the rehabilation works ‘A total of 81,948 people were made to stay in 471 camps during the cyclone Gaja, which helped in saving a lot of lives. The relief package for people who lost their boats during cyclone Gaja will be increased from Rs 85,000 to 1.50 lakh,’ he stated. HC vacates stay on online sale of medicines The Madras High Court on Wednesday lifted the ban on online sale of medicines till statutory rules to regulate the trade were notified by the Un- ion government. A Division Bench comprising Justice M Sathyanaraynan and Justice P Rajamanickam stayed the operation of a 17 December single judge order, banning online sale of medicines. The Judges said if online trade was prohibited all of a sudden, it would affect the needy patients and those who have already placed orders for medicines. The Bench, pass- ing interim orders on a batch of writ pleas filed by e-pharma firms, said para 38 (relating to ban) of the single judge’s order shall remain stayed until the disposal of the appeals which were ordered to be listed for final hearing on 24 January. Jaya death: C Ve Shanmugam raises serious doubts ‘Why was Amma (former Chief Minister J Jayalalithaa) not given An- gioplasty? What stopped the doctors from giving treatment and who told them not to give Angio?’ These were some of the questions raised by Min- ister for Law, Courts and Prisons, C Ve Shanmugam, who expressed his doubts over the medical treatment given to the AIADMK supremo when she was hospitalised before her death in 2016. Speaking to reporters in Villupuram, the Minister said there was a mystery surrounding former Chief Minister’s death. He said, ‘If proper treatment was given to Puratchi Thalaivi, she was would have been alive today. Why wasn’t she taken abroad for better treatment?’ Targetting the Health Minister and top government officials, Shanmugam said, ‘Health Minister Vijaya Bhaskar, Health secretary Radhakrishnan and the then Chief Secretary Ram Mohan Rao should be taken into police custody and questioned for the truth to come out.’ Chennai Book Fair begins With at least 1.5 crore books for sale, the 42nd edi- tion of Chennai Book Fair got a kickstart in the city Friday evening. After inaugurating the event, Chief Minister Edappadi K Palaniswami asked all parents to start reading books so that they can cultivate the habit in their children. He was speaking at the fair organised by the Booksellers and Publishers Association of South India (BAPASI) at YMCA, Nandanam. The event will go on till January 20. There are 820 stalls and over 1.5 crore books across 12 lakh subjects. The fair will be open between 2 pm and 9 pm on weekdays and between 11 am and 9 pm on weekends and public holidays. Ayodhya case: SC’s important order 10 Jan The Supreme Court said an appropriate bench constituted by it will pass an order on 10 Janu- ary for fixing the date of hearing in the Ram Janmabhoomi-Babri Masjid land dispute title case at Ayodhya. ‘Further orders will be passed by an appropriate bench on January 10 for fixing the date of hearing the matter,’ a bench com- prising Chief Justice Ranjan Gogoi and Justice S K Kaul said. No sooner the matter came up, the CJI said it is the Ram Janmabhoomi- Babri Masjid case and went ahead with passing the order. Senior advocates Harish Salve and Rajeev Dhavan, appearing for different parties, did not even get the opportunity to make any submission. The hearing did not even last 30 seconds. Protests in Kerala after 2 women enter Ayyappa Shrine Two women in their 40s on Wednesday entered Kerala’s Sabarimala temple sparking violent clashes. It was the first time that women aged between 10 and 50 entered the Lord Ayyappa temple in Kerala since Supreme Court overturned a ban in September last year. The dramatic pre-dawn entry by the two women, Bindu and Kanaka Durga, helped by policemen wearing civilian clothes, led to angry reactions from opposition parties. Bindu and Kanaka Durga said they had ‘darshan’ at 3.30 am, away from the media glare. Protests erupted across Kerala soon after news of the women trekking to the hill shrine spread. The temple itself was closed for over an hour for purification. Coronation of Thai King in May An elaborate three-day coronation ceremony for Thailand’s King Maha Vajiralongkorn will be held in early May, more than two and half years after the death of his revered father Bhumibol Adulyadej. The 66-year-old ascended the throne following his father’s death in October 2016, which ended a tumultuous seven-decade reign over the Southeast Asian kingdom marked by coups and rounds of violent street protests. Maha Vajiralongkorn, formally known as Rama X of the Chakri dynasty, has since dramatically reorganised palace affairs. He has bolstered his own security detail and granted himself personal stewardship of the crown’s multi-billion dollar assets, which include swathes of prime real estate and major investments in banks and com- panies. Thailand’s monarchy one of the world’s richest ‘ is shielded from criticism by a harsh royal defamation law punishing any transgressors with up to 15 years per charge. Kim’s warning to USA Nuclear-armed North Korea wants good relations with the US but could consider a change of approach if Washington maintains its sanctions, leader Kim Jong Un warned in his New Year speech on Tuesday after 12 months of diplomatic rapprochement. At a summit with US President Donald Trump in Singapore in June the two signed a vaguely worded pledge on denuclearisation of the Korean peninsula. But progress has since stalled with Pyongyang and Washington arguing over what that means. If the US fails to carry out its promise to the world and remains unchanged in its sanctions and pressure upon the DPRK, Kim said Tuesday, ‘we might be compelled to explore a new path for defending the sovereignty of our country and supreme interests of our state’. He was willing to meet Trump again at any time, he added, ‘to produce results welcomed by the international community’. NSEL scam: Govt did not make any recommendation The government has said it has not made any recommendation to the NCLAT for declaring brokers involved in the payment crisis at the NSEL as ‘not fit and proper’, as such power lies with markets regulator Sebi. The Rs 5,600-crore National Spot Exchange Ltd (NSEL) payment scam came to light in 2013. ‘The Ministry of Corporate Affairs has not made any recommendation to the National Company Law Appellate Tribunal (NCLAT) for declaring brokers involved in the payment crisis at NSEL as not fit and proper,’ Minister of State for Finance, Pon Radhakrishnan, said in a written reply to the Lok Sabha. Such powers to declare not fit and proper lies with the Securities and Exchange Board of India (Sebi), he added. Birla Corp enters construction additives biz Birla Corporation, the flagship company of the M P Birla Group, has entered the construction chemicals and wall putty segments as additives, the company has said. Birla Corporation is one of Indias top cement makers, with an annual production capacity of 15.5 million tonnes. Sales of construction chemicals and additives in India are expected to grow at a compounded annual rate of around 15 per cent till 2025, the company said in a statement citing research. A wide variety of chemicals and ad- ditives are being developed and used in new age construction, and the market for these is expected to grow both vertically and horizontally, the company said. Special poojas and daily alankarams were performed for Bhaktha Anjaneya Swamy at Vaikundavasa Perumal Temple, Koyambedu for Hanumath Jayanthi, observed recently.
