London, June 27 (IANS) Men -- more often than women -- need passion to succeed at things. It is because they secrete more dopamine, often called the "happy hormone", suggests a study.At the same time, the hormone may also be responsible for increased incidences of autism spectrum in boys than girls.Dopamine is a neurotransmitter that is released in the brain. It can contribute to a feeling of satisfaction. The effects of dopamine are linked to learning, attention and our ability to focus."This is interesting. Research shows a more active dopamine system in most men" than in women, said Hermundur Sigmundsson, Professor at the Norwegian University of Science and Technology's (NTNU) Department of Psychology.The study, published in the journal New Ideas in Psychology, tested 917 people (502 women and 415 men) aged 14 to 77, to understand men and women's differing activity in the dopamine system."We looked at gender differences around passion, self-discipline and positive attitude," Sigmundsson said. The study refers to these qualities as passion, grit and mindset.The results for the women, however, are somewhat more ambiguous than men's strong need to burn for something, and this study found no such gender difference, the researchers said.While the dopamine system has earlier been associated with different conditions, such as ADHD, psychoses, manias and Parkinson's disease, the new study found it may be also linked to a certain form of autistic behaviour.Some individuals with autism may become very interested in certain topics, which can be a bit unusual, or even strange, for most people. People on the autism spectrum can focus intensely on these topics or pursuits, at least for a while. Dopamine may play a role."Other research in neuroscience has shown hyperactivity in the dopamine system in individuals with autism, and boys make up four out of five children on the autism spectrum. This, and dopamine's relationship to passion, might be a mechanism that helps to explain this behaviour," Sigmundsson noted.--IANSrvt/sdr/
New Delhi, June 3 (IANS) The Supreme Court on Thursday said, it is happy that the board exams have been cancelled and emphasized that the interest of students will be protected, as it asked the Centre to submit the objective criteria to assess Class XII students in two weeks.At the beginning of the hearing, the Attorney General K.K. Venugopal submitted he had circulated a letter by the government in the matter. A bench comprising Justices A.M. Khanwilkar and Dinesh Maheshwari told the AG, "We are happy with the Centre's decision to cancel the board exam (CBSE and ICSE boards). But what is the objective standard principle you will apply? The criteria have not been given in the letter."The AG replied to the bench that the objective criteria will be determined by CBSE and sought time to place it on record before the court. The AG submitted the petition seeking cancellation of board exams may be disposed and an application could be filed in the matter. The bench replied that it will only dispose of the matter after the objective criteria is placed on record. The ICSE board counsel sought four weeks' time to place the objective criteria on record.Declining to give four weeks to both CBSE and ICSE, the bench said: "If you want you can do overnight, but we are giving you two weeks. All interactions are happening online, do it in two weeks. You should act overnight."Justice Maheshwari said: "Last year they have taken the decision, why they are asking for more time." The bench said the decision in the matter has to be taken early, as there are many students who want to take admission in foreign universities. Declining to give four weeks' time, the bench reiterated: "it will delay, urgent decision should be taken."Petitioner advocate Mamta Sharma pointed out that some state boards are still going ahead with the exams. Asking the lawyer to be patient, the bench replied: "We have interest of the students in our minds, irrespective of the board. Let this be resolved first and then we will consider the other state board exams."--IANSss/skp/

New York- If your teenage child has memories of a happy childhood, they are less likely to indulge in drinking or substance abuse and enjoy learning, a new study suggests.
The findings, published in the journal Addiction Research and Theory, indicated that positive attitudes towards the past, present and future put adolescents at lower risk of alcohol use, binge drinking and marijuana.
"Many teenagers also aren't engaging with online learning during Covid-19 or have lower engagement levels," said researcher John Mark Froiland from Purdue University in Indiana, US.
"But they are more likely to be enthusiastic learners and not use drink and drugs if teachers take time to build more positive relationships with them. They can help students see that everything they are learning is truly valuable. Parents have a role to play too," Froiland added.
For the study, the team assessed 1,961 students at a high school and half (53 per cent) of the pupils included in the study were female.
The researchers looked at responses from pupils where they rated how nostalgic they were of their childhood, current happiness levels in life and how much they look forward to future happiness.
They also analysed marijuana and alcohol habits over the past 30 days including binge drinking, and average academic grades. They analysed motivation levels, and behaviour in lessons such as how much teenagers paid attention and listened.
Statistical techniques were used by the researchers to assess the associations between all these different factors and establish the key predictors for alcohol and marijuana misuse.
The researchers are calling on teachers and parents to help students develop more positive mindsets and become motivated to learn so they are less likely to binge drink or use marijuana.
The aim of this study was to establish how substance misuse and behaviour towards learning are affected by students' feelings about the past, present and future. (Agency)
Noting that the prevalence of spine problems has increased manifold during the COVID-19 lockdown, a senior Delhi-based doctor says that looking at the increasing number of spine-related cases, it would not be an overstatement to say that there is a silent epidemic building up.
The associated factor is the forced sedentary lifestyle, and prolonged sitting, lack of exercise and poor activity. Poor understanding of spine ergonomics leads to improper posturing and is also contributory, explains Dr. Samir K Kalra, Consultant, Department of Neurosurgery, Sir Ganga Ram Hospital.
"Spine related consultations have increased and the reason is the primarily sedentary lifestyle that has been forced upon us by the disease. There has been a significant change in daily routine activities in almost everyone's lifestyle in this lockdown period. Backache is considered amongst the most common occupational disorders leading to work-related absenteeism. Neck pain is equally distressing and appalling. They cause a huge economic burden and could become a major constraint in our already weakened economy" Dr. Kalra told IANSlife.
Asked which demographic is most at risk, the doctor points to the elderly among the subsets of people who have been affected more in this period.
"The fact that they already have compromised and weak spinal musculatures along with forced inactivity leading to increased spinal load. The main support for the spine comes from the muscles and it is important to keep them supple and strong. It is difficult for the elderly to do so."
Another subset is professionals working from home, the doctor explains. "Working from home and on laptops for long periods has resulted in a lot of back and neck related issues. This includes not only professionals but also teachers and students who suddenly have been forced to sit for hours and work on screens.
The women of the house are another subset affected due to the additional housework due to lack of domestic help. This coupled with additional stress and anxiety due to the COVID pandemic which is common to all affected people causes a compounding effect."
5 Preventive Tips for Spine Problems
One has to understand that spine mechanics are different for each individual. While there are certain common preventive ways, each person has to understand and make their own adjustments.
This would include individualized height adjustments for everyone during sitting and ambulation based on height, weight, spine length, limb length, and neck angulations. This is easily done and can be preventive of a major morbid situation.
Periodic breaks and stretches also are required to reduce spinal strain.
Attention to posture while sleeping is also important essentially including the correct pillows and mattresses. The spine is a complex system with a limited shelf life, and only by good care, we can keep it healthy and functioning.
It is not the amount of work or the load it bears which causes wear and tear but more so the work is done in the wrong positions which lead to damage.
New Delhi, Dec 31 (IANS) As India awaits with bated breath for a silver bullet against coronavirus, the Drug Controller General of India (DCGI) on Thursday hinted at the approval of vaccine and said the country will have a 'happy new year with something in hand.'The drug regulator is currently analysing the data submitted by Serum Institute of India, which is manufacturing Oxford-AstraZeneca vaccine and Bharat Biotech, which is making indigenous vaccine in collaboration with ICMR. The expert panel will convene a meeting on January 1 on this."The industry and research organisation have stood the test of time. It has been a very wonderful experience. Probably, we will have a happy new year with something in hand. That is what I can hint at," Drug Controller General of India (DCGI) V.G. Somani said.On Wednesday, the Subject Expert Committee (SEC) of the Central Drugs Standard Control Organisation (CDSCO) had met to consider the Emergency Use Authorisation (EUA) request of Pfizer, Serum Institute of India and Bharat Biotech Private Limited.Further time was, however, requested on behalf of Pfizer. Additional data and information presented by SII and Bharat Biotech was then perused and analysed by the expert panel. The analysis of the additional data and information is going on and it will convene again on January 1, the Centre had said in a statement.America's Pfizer was the first one to apply for the accelerated approval on December 4, followed by Serum and Bharat Biotech who applied on December 6 and 7, respectively. Pfizer had, however, requested more time to make a presentation before the committee.On December 9, the Subject Expert Committee asked Serum Institute of India and Bharat Biotech to submit more data and information to get approval.The expert panel had then recommended Serum to submit the outcome of the assessment of the UK-MHRA for grant of emergency use approval, the updated safety data of the Phase II/III clinical trial and immunogenicity data from the clinical trial in the UK and India.Bharat Biotech was recommended to present the safety and efficacy data from the ongoing Phase III clinical trial in the country for further consideration.Their applications were reviewed again on Wednesday hours after the UK accepted the recommendation of the Medicines and Healthcare Regulatory Agency (MHRA) to authorise Oxford University-AstraZeneca's Covid-19 vaccine, named Covishield, for emergency use.The authorisation was significant for India as the Pune-based Serum Institute of India had tied up with the company to conduct clinical trials and manufacture vaccine.The Central government plans to vaccinate nearly 30 crore people in the first phase of drive. It will be offered to one crore healthcare workers, along with two crore frontline and essential workers and 27 crore elderly, mostly above the age of 50 years with comorbidities.As many as eight Covid-19 vaccine candidates are under different stages of clinical trials which could be ready for authorisation in near future, including three indigenous vaccines.It includes AstraZeneca and Oxford university developed and Serum Institute of India manufactured Covishield, Covaxin by Bharat Biotech Limited, ZyCoV-D by Zydus Cadila and Russian vaccine candidate Sputnik-V.The list also contains NVX-CoV2373 by SII, HGCO19 by Geneva, and two unlabelled vaccines-Recombinant Protein Antigen based vaccine by Biological E Limited-and Inactivated rabies vector platform by Bharat Biotech.--IANSaka/dpb
