Scientists map melting history of Greenland’s ice sheet

September 17, 2009 By admin Leave a Comment

Washington, September 17 (ANI): Researchers from the Niels Bohr Institute at the University of Copenhagen have mapped the history of the melting of the Greenland ice sheet.

Numerous drillings have been made through both Greenland’s ice sheet and small ice caps near the coast.

By analyzing every single annual layer in the kilometres long ice cores, researchers can get detailed information about the climate of the past.

But now, the Danish researcher Bo Vinther and colleagues from the Centre for Ice and Climate at the Niels Bohr Institute, University of Copenhagen, in collaboration with researchers from Canada, France and Russia, have found an entirely new way of interpreting the information from the ice core drillings.

“Ice cores from different drillings show different climate histories. This could be because they were drilled at very different places on and near Greenland, but it could also be due to changes in the elevation of the ice sheet, because the elevation itself causes different temperatures,” explained Bo Vinther about the theory.

Today, the ice sheet is more than three kilometres thick at its highest point and thinning out towards the coast.

Four of the drillings analyzed are from the central ice sheet, while two of the drillings are from small ice caps outside of the ice sheet itself.

By comparing the Oxygen-18 content in all of the annual layers from the four drillings through the ice sheet with the Oxygen-18 content of the same annual layers in the small ice caps, Bo Vinther has calculated the elevation course through 11,700 years.

Just after the ice age the elevation of the ice sheet rose slightly because when the climate transitions from ice age to warm age, there is a rapid increase in precipitation.

But at the same time, the areas lying near the coast begin to decrease in size, because the ice is melting at the edge.

When the ice melts at the edge, it slowly causes the entire ice sheet to ‘collapse’ and become lower.

The calculations show that in the course of about 3,000 years, the elevation changed and became up to 600 meters lower in the coastal areas.

But in the middle, it was a slow process, where the elevation decreased around 150 meters in the course of around 6,000 years.

It then stabilized.

The new results show the evolution of elevation of the ice sheet throughout 11,700 years and they show that the ice sheet is very sensitive to the temperature.

The results can be used to make new calculations for models predicting future consequences of climate changes. (ANI)

‘Two for one’ breast boosting technique not as viable as it seems

September 17, 2009 By admin Leave a Comment

London, Sep 16 (ANI): A technology that was claimed as the ultimate solution to give a boost to women’s breasts by using fat removed from thighs is not viable as it seems, say experts.

Mel Graham, chairman of the Harley Medical Group, recently claimed that the “two for one” procedure could extract excess fat from where it was not wanted – the belly, hips or thighs – and relocate it to the bust.

However, rival cosmetic surgeons criticised the “hype” surrounding the new operation, insisting that it was “premature”.

“(This) is setting consumers up for disappointment and there are many reasons for vigilance,” the Independent quoted Dai Davies, of Plastic Surgery Partners in Harley Street, as saying.

He said that doctors have long been experimenting with innumerable aids to give women larger busts, including using body fat as a procedure.

The technique of removing fat by liposuction, and then injecting it into the chest has been tried for almost 20 years but with limited success, said Davies.

“Where you are injecting small amounts of fat into the face, which has a good blood supply, there is good evidence that it works. Most plastic surgeons would agree there is a place for it. But this involves injecting a large blob of fat into the breast area. Fat consists of living cells and living cells must have a blood supply, otherwise they die,” he explained.

In a Japanese study last year, 230 women underwent fat transfer, and it was found that, on average, half the fat injected was lost and all the women needed a second procedure after a year.

There are also fears that dying fat cells could cause micro-calcification in the breast leading to difficulties in breast screening and an increase in biopsies – an invasive procedure to remove tissue to check for cancer.

“I don’t think we should be a testing ground for all these techniques. You are feeding on a susceptible group of people. There should be controls but, sadly, the Government has decided it won’t implement regulation,” said Davies.

Professor David Sharpe, a plastic surgeon in Yorkshire and the founding chairman of the breast special interest group of BAAPS, said: “This sounds like another example of creative marketing. Breast implants are a well-tried and tested method. At the moment, I would stick with that.”

Mel Braham, chairman of the Harley Medical Group, said results of a US trial to be presented next month would demonstrate the success of the operation.

“The results will be assessed by our medical board and, if approved, the operation will be introduced next year. I don’t take risks with patients. I am confident this is a safe procedure,” he said. (ANI)

Changes in humidity, temperature may trigger asthma among kids

September 15, 2009 By admin Leave a Comment

Washington, September 15 (ANI): Changes in humidity and temperature may trigger asthma among kids, suggests a report.

Published in the journal Annals of Allergy, Asthma and Immunology, the report says that such weather changes have been found to result in a rise in Emergency Department (ED) visits for paediatric asthma exacerbations.

“We found a strong relationship between temperature and humidity fluctuations with pediatric asthma exacerbations, but not barometric pressure,” said Dr. Nana A. Mireku, an allergist at Dallas Allergy Immunology private practice in Dallas, formerly at Children’s Hospital of Michigan, Wayne State University School of Medicine, Detroit.

“To our knowledge, this is the first study that demonstrated these correlations after controlling for levels of airborne pollutants and common aeroallergens.

“Our study is also one of the few to examine the possibility that the weather one or two days before the asthma exacerbation may be as important as that on the day of admission, as the additional ED visits occur one to two days after the fluctuation,” she added.

The authors of the report write that patients experiencing an asthma attack often complain that weather fluctuations are a major trigger.

Dr. Mireku said: “the latest National Institutes of Health guidelines list ‘change in weather’ as a possible precipitating factor for asthma, but no previous studies have really examined this potential trigger in a rigorous fashion.”

According to the report, the retrospective 2-year study was performed at a large urban hospital of 25,401 children visiting the ED for an asthma exacerbation.

The researchers collected data on climactic factors, pollutants and aeroallergens on a daily basis.

They used time series analysis to evaluate the relationship of daily or between-day changes in climactic factors and asthma ED visits, controlling for seasonality, air pollution and aeroallergen exposure.

The effects of climactic factors were evaluated on the day of admission and up to five days before admission.

The researchers found that a 10 percent daily increase in humidity on a day or two before admission was associated with approximately one additional ED visit for asthma.

The authors write that between-day changes in humidity from two to three days prior to admission were also associated with more ED visits.

Daily changes in temperature on the day of or the day before admission increased ED visits, with a 10 degree F increase being association with 1.8 additional visits.

“Asthma is the most common chronic illness in childhood. Allergists have long known that weather conditions such as extremely dry, wet or windy weather can affect asthma symptoms. This study further defines the role of temperature and humidity on children’s asthma and confirms the importance of working with patients to identify the source of their symptoms and develop treatment plans that help prevent them,” said allergist Richard G. Gower, president of the American College of Allergy, Asthma and Immunology (ACAAI). (ANI)

Your bathroom showers are hazardous to health

September 15, 2009 By admin Leave a Comment

Washington, September 15 (ANI): That invigorating relief and good cleansing from daily bathroom showers may bring along a face full of potentially pathogenic bacteria, warn researchers at the University of Colorado at Boulder.

Using high-tech instruments and lab methods, the researchers analysed roughly 50 showerheads from nine cities in seven states that included New York City, Chicago and Denver.

CU-Boulder Distinguished Professor Norman Pace, lead study author, says that about 30 percent of the devices were found to harbour significant levels of Mycobacterium avium, a pathogen linked to pulmonary disease that most often infects people with compromised immune systems, but which can occasionally infect healthy people.

The study showed that some M. avium and related pathogens were clumped together in slimy “biofilms” that clung to the inside of showerheads at more than 100 times the “background” levels of municipal water.

“If you are getting a face full of water when you first turn your shower on, that means you are probably getting a particularly high load of Mycobacterium avium, which may not be too healthy,” Pace said.

He pointed out that research at National Jewish Hospital in Denver indicated that increases in pulmonary infections in the US in recent decades from so-called “non-tuberculosis” mycobacteria species, such as M. avium, could be attributed to people taking more showers and fewer baths.

He said that water spurting from showerheads could distribute pathogen-filled droplets that suspend themselves in the air, and could easily be inhaled into the deepest parts of the lungs.

“There have been some precedents for concern regarding pathogens and showerheads. But until this study we did not know just how much concern,” said Pace.

In Denver, according to the researcher, one showerhead with high loads of Mycobacterium gordonae was cleaned with a bleach solution in an attempt to eradicate it, but tests conducted several months later showed that the bleach treatment ironically caused a three-fold increase in the pathogen, indicating a general resistance of mycobacteria species to chlorine.

Ask Pace whether it is dangerous to take showers, and he says: “Probably not, if your immune system is not compromised in some way. But it’s like anything else-there is a risk associated with it.”

He stresses that plastic showerheads appear to “load up” with more pathogen-enriched biofilms, and thus metal showerheads may be a good alternative.

“There are lessons to be learned here in terms of how we handle and monitor water. Water monitoring in this country is frankly archaic. The tools now exist to monitor it far more accurately and far less expensively that what is routinely being done today,” said Pace.

A research article on his study has been published in the online edition of the Proceedings of the National Academy of Sciences. (ANI)

Faster, simpler Facebook Lite site available in India, US

September 12, 2009 By admin Leave a Comment

London, Sep 12 (ANI): Social networking site Facebook has launched a slimmed-down version of its site for people with slow or poor Internet connections, and it is currently available only in India and the US.

Facebook’s Lite site, which will be faster and simpler because it offers fewer services than the main site, had initially been meant to support users in developing countries, where bandwidth constraints make the current version too slow to use.

The company said around 70 percent of its more than 250 million users were from outside America, with countries in Southeast Asia and Europe seeing a massive increase in growth where fast Internet connections are more common.

News about Facebook testing the Lite site first leaked out in August, with its options said to be limited to letting users write on their wall, post photos and videos, view events and browse other people’s profiles.

“It appears, at a quick glance, to be a better site for Facebook newbies or for anyone who finds the current site overwhelming and noisy,” the BBC quoted Rafe Needleman at technology website Cnet as saying.

“The new layout feels almost Twitter-like,” he said.

Terence O’Brien at Switched.com gave the slimmed-down version of what he called “ol’ blue” the thumbs-up because it “strips away distractions”.

“The simple site loads noticeably faster, is easier to navigate, and is much easier on the eyes thanks to the lack of people sending you ‘virtual booze’ or asking you to join their ‘vampire fraternity’,” he said.

“The new layout seems like a direct challenge to Twitter, which can attribute much of its success to is simplicity and portability,” he stated.

Many industry watchers said they believed that even users with good Internet connections might well flock to Facebook Lite because of its new look and ease of use.

“That is what some US users are planning to do,” Eric Eldon of InsideFacebook.com said.

“Indeed the reaction from US users has prompted Facebook to release it intentionally for US users, something it hadn’t previously planned on doing,” he added.

Eldon also said he believed a “worldwide rollout doesn’t seem too far away”.

Facebook has acknowledged this is a possibility in a statement on the site, which said the firm was “working on translating Lite into other languages”.

Anyone who switches to Facebook Lite and does not like it can switch back to the fuller version of the site. (ANI)

Taliban now terrorise 80% of Afghanistan after eight years of war: Report

September 12, 2009 By admin Leave a Comment

Kabul, Sep. 11 (ANI): Almost eight years after the war began in Afghanistan in the aftermath of the 9/11 carnage, the Taliban insurgency has spread across 80 percent of the country.

The violent incidents this week have drawn attention to the deteriorating security situation of northern Afghanistan, which had largely remained peaceful so far, the Christian Science Monitor reports.

The northern provinces are facing difficult times as heavy insurgent activity has spread to 80 percent of the country – up from 54 percent two years ago, the report says.

The militants’ focus has shifted to northern parts following continuous pressure from their Pakistani counterparts to attack NATO’s second supply route situated here, it adds.

“[Militants] have been trying to widen the ground for the insurgency in Afghanistan and now they have got momentum. The militants are eager to target this route to prevent a smooth supply chain from northern Afghanistan,” the report quoted Waliullah Rahmani, executive director of the Kabul Center for Strategic Studies, as saying.

Last week’s airstrike targeted two fuel tankers headed to supply NATO troops in Kabul that had been hijacked by the Taliban.

Although the increase in violence is only a recent phenomenon, the conditions had worsened long ago, the report says.

The violence can be linked to districts with large Pashtun populations, whose grievances the government has failed to address – making them sympathetic to the Taliban, who share their ethnicity and language, it adds.

“The districts which are turning violent are those which have had a very recent history of abuses against the Pashtuns.

The government has allowed these conditions to go unaddressed and this is now being addressed by the population by giving shelter to the Taliban and other insurgents,”the report quoted Prakhar Sharma, the head of research at the Center for Conflict and Peace Studies, as saying.(ANI)

Exposure to second-hand tobacco smoke linked to liver disease

September 12, 2009 By admin Leave a Comment

Washington, September 11 (ANI): People can develop liver disease even when they are exposed to second-hand tobacco smoke, according to a study.

Scientists at the University of California, Riverside (UCR) have found that exposure to second-hand tobacco smoke can lead to non-alcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury wherein fat accumulates in the liver of people who drink little or no alcohol.

For their study, the researchers exposed some mice to second-hand cigarette smoke for a year in the lab, and observed fat build-up in their liver cells, a sign of NAFLD that eventually leads to liver dysfunction.

The researchers focused on two key regulators of lipid (fat) metabolism that are found in many human cells as well: SREBP (sterol regulatory element-binding protein) that stimulates synthesis of fatty acids in the liver, and AMPK (adenosine monophosphate kinase) that turns SREBP on and off.

They found that second-hand smoke exposure inhibits AMPK activity, which, in turn, causes an increase in activity of SREBP.

More active SREBP results in more fatty acids getting synthesized, they say.

The result is NAFLD induced by second-hand smoke, according to the researchers.

“Our study provides compelling experimental evidence in support of tobacco smoke exposure playing a major role in NAFLD development,” said Manuela Martins-Green, a professor of cell biology, who led the study.

“Our work points to SREBP and AMPK as new molecular targets for drug therapy that can reverse NAFLD development resulting from second-hand smoke. Drugs could now be developed that stimulate AMPK activity, and thereby inhibit SREBP, leading to reduced fatty acid production in the liver,” Martins-Green added.

A research article describing the study has been published in the Journal of Hepatology. (ANI)

With lifestyle diseases on the rise, healthcare should be future focus: Ansari

September 10, 2009 By admin Leave a Comment

Ranchi (Jharkhand), Sep.10 (ANI): Vice President M Hamid Ansari on Thursday said with the number of lifestyle diseases increasing, healthcare facilities should be strengthened to meet future demands of the country.

“The facilities we have is sufficient for now, but not sufficient for future,” Ansari said while dedicating the new HCG Curie-Abdur Razzaque Ansari Cancer Institute (C-ARACI) to the nation.

He said there has been huge progress in healthcare in the country, but the increase in new diseases has also kept in tandem with the improving system.

“There weren’t too many diseases 50 years ago. But now there has been an increase (in diseases) following changing lifestyles and diagnosis of new diseases,” he added.

Ansari said development of the health sector was crucial in maintaining the happiness index.

“A healthy person is a happy person. An ailing person, howsoever rich, is an unhappy person,” Ansari said while lauding the contribution of non-governmental institutes like Ranchi’s C-ARACI in developing health care facilities. (ANI)

Here’s why sugar in green tea is a healthy idea

September 10, 2009 By admin Leave a Comment

Washington, Sept 10 (ANI): A new study has shown that adding ascorbic acid and sugar to green tea can help the body easily absorb helpful compounds that help fight health problems.

Mario Ferruzzi, lead researcher and associate professor of food science and nutrition at Purdue University, insists that adding ascorbic acid to green tea would increase the absorbability of catechins found in the tea.

Catechins, a class of polyphenols common in tea, cocoa and grape, are antioxidants thought to fight heart disease, stroke, cancer, diabetes and other health problems.

Ascorbic acid, sucrose or both together increase by as much as three times the amount of catechins that can be absorbed into the bloodstream.

According to Ferruzzi, Elsa Janle, a Purdue associate research professor of foods and nutrition, and Catrina Peters, the new study also demonstrates the effectiveness of a model that could reduce the number of animals needed for these types of studies.

The model charts how the digestive stability, solubility and absorption of polyphenols changes based on modifications to a beverage’s formula.

Ferruzzi said testing with the model could allow researchers to predict how a new product formula might change the product’s properties, reducing the number of animals needed for testing to only products that showed desired characteristics in the model.

The study backed up the model study that showed adding sugar and vitamin C to green tea enhanced the body’s ability to absorb polyphenols.

Ferruzzi said that adding lemon juice or other citrus juice to tea would do the trick, or consumers could look for ready-to-drink products that contain 100 percent of the recommended amount of vitamin C or ascorbic acid on the ingredient list.

“Having that vitamin C seems to do it,” Ferruzzi said. “And if you don’t want to squeeze a lemon into your cup, just have a glass of juice with your green tea.”

The study appears in journal Food Research International. (ANI)

Assam’s Orang National Park to have anti-poaching camps

September 10, 2009 By admin Leave a Comment

Guwahati (Assam), Sep 9(ANI): The Assam Government on Wednesday said that it would set up five anti-poaching camps in the Orang National Park in order to prevent the poaching of the endangered one-horned rhinos.

The decision came in the wake of a stark increase in the number of poaching incidents that were reported from the park.

Earlier, Assam Forest Minister Rockybul Hussain had ordered a high-level probe. Several administrative officials, including Chief Conservator of Forest B S Bonal, had visited the park in order to prepare a report.

According to reports, along with the five anti-poaching camps, there will be two floating camps in the river. Meanwhile, twenty armed home guards and one assistant conservator of forest would be deployed to supervise the measures. (ANI)

Novel biosensor can detect typhoid bacteria instantly

September 10, 2009 By admin Leave a Comment

Washington, Sept 9 (ANI): Scientists from Rovira i Virgili University (URV) in Tarragona have come up with a novel biosensor that can instantly detect Salmonella typhi, the bacteria that causes typhoid fever.

The technique uses carbon nanotubes and synthetic DNA fragments that activate an electric signal when they link up with the pathogen.

“We have developed a new biosensor that can detect extremely low concentrations of bacteria immediately, easily and reliably”, F. Xavier Rius, lead author of the study and a professor in the Chemometrics, Qualimetrics and Nanosensors research group in the Analytical Chemistry and Organic Chemistry Department of the URV, told SINC.

The new biosensor functions using a method, which involves carbon nanotubes with inbuilt aptamers providing electrochemical readings.

According to the researchers, the aptamers are small fragments of artificial DNA or RNA designed to attach themselves specifically to a particular molecule, cell or micro organism, in this case Salmonella.

If the bacteria are not present, the aptamers remain on the walls of the carbon nanotubes.

However, if they detect bacteria, they become activated and stick to it, and the carbon nanotubes generate an electric signal that is picked up by a simple potentiometer connected to the biosensor.

“The presence of the bacteria sparks a change in the interaction between the aptamers and the nanotubes, which takes place in a few seconds and creates an increase in the voltage of the electrode”, said Ruis, who led the research along with researcher Jordi Riu.

“This technique means small quantities of micro organisms can be detected simply and practically in real time, just the same as measuring the pH of water”, Ruis added.

The study appears in the scientific journal Angewandte Chemie International Edition. (ANI)

Older Oz women going online to meet new sexual partners

September 7, 2009 By admin Leave a Comment

Sydney, Sept 7 (ANI): Women aged 40 and above are just as likely as younger women to meet new sexual partners on the internet, according to a new Australian survey.

Nearly 45 per cent of the middle aged women agreed to snaring at least one new lover in a year.

According to study leader Deborah Bateson, a senior medical coordinator at Family Planning NSW, the internet “seems to be a very useful place for them … It’s great that older women are out there meeting new partners.”

She conducted the research to see whether 40-pluses were able to negotiate safe sex as effectively as their younger counterparts.

“Three-quarters [of sexually transmitted infections] are detected in people aged under 29, but there’s also an increase in women aged 40 and above … entering or re-entering the dating market, perhaps after the end of a long-term relationship,” the Sydney Morning Herald quoted Bateson as saying.

For the survey, an online dating site RSVP, owned by the Herald’s publisher, Fairfax Media, sent an email to female participants, directing them to Bateson’s survey site.

The findings revealed that older women were more forthright in insisting on knowing a new partner’s sexual history.

Nearly 59 per cent of the over-40s would ask about previous partners, versus 43 per cent of the younger women, with a similar discrepancy in willingness to ask about intravenous drug use.

“The older women seemed to benefit from the maturity of years and asked those potentially tricky questions,” said Bateson.

However, 37 per cent of the older women were more likely to agree to sex without a condom, compared to 28 per cent of younger women.

The findings were presented at 2009 Australasian Sexual Health Conference in Brisbane. (ANI)

London Mayor blasted for asking Brits to fast like Muslims during Ramadan

September 5, 2009 By admin Leave a Comment

London, Sep 5 (ANI): The Mayor of London, Boris Johnson, has been criticized for asking Brits to fast for a day so they would know what it is like to be a Muslim.

Johnson said people should starve themselves from dawn until dusk during Ramadan and then end their fast during a visit to their local mosque.

Steve Uncles, South East chairman of the English Democrats, blasted Johnson’s comments.

He said: “The indigenous culture of this country is based on Christianity and Paganism. Of course, as an open and tolerant society, if people want to practise other religions then good luck to them. But the state should not be funding them because otherwise we will lose our culture.”

Johnson, 45, was visiting the East London Mosque and London Muslim Centre when he made these comments, the Daily Star reported.

“Whether it’s in theatre, comedy, sports, music or politics, Muslims are challenging the traditional stereotypes and showing that they are, and want to be, a part of the mainstream community.

“That’s why I urge people, particularly during Ramadan, to find out more about Islam, increase your understanding and learning, even fast for a day with your Muslim neighbour and break your fast at the local mosque,” Johnson said.

He added: “There are valuable lessons that people of all backgrounds can learn from Islam, such as the importance of community spirit, family ties, compassion and helping those less fortunate, all of which lie at the heart of the teachings of Ramadan.” (ANI)

How economic recessions affect public health

September 1, 2009 By admin Leave a Comment

Washington, September 1 (ANI): A new study suggests that mortality rates during economic recessions in developed countries decline rather than increase.

Publihsed in the Canadian Medical Association Journal (CMAJ), the study also suggests that in poor countries where GDP per capita is less than 5,000 dollars, economic growth appears to improve health by increasing access to food, clean water, shelter, and basic health services.

“In terms of business cycles, mortality is procyclical, meaning it goes up with economic expansions and down with contractions, and not countercyclical (the opposite), as expected,” writes Dr. Stephen Bezruchka, from the School of Public Health, University of Washington in Seattle, USA.

The author points out that studies on wealthy countries show that greater national wealth does not equate with better health for its citizens.

“The United States, with the highest GNP per capita in the world, has a lower life expectancy than nearly all the other rich countries and a few poor ones, despite spending half of the world’s health care bill,” he states.

It also has the highest poverty levels of any wealthy country, with large health disparities and poor health outcomes.

Countries like Sweden, which have strong social safety nets and strong labour protection, see smaller changes in the health of its citizens during recessions.

Bezruchka says that studies have shown that unemployment can be bad for people’s health, yet smoking, excessive alcohol consumption and overeating decline during recessions with beneficial impacts on health.

Perhaps even more importantly, adds Bezruchka, when unemployment rates soar, people have more time for friends, family, and children.

That, according to him, results in lower mortality.

“If we recognize that economic growth may not be good for our health, then we can consider means of reining in the excess wealth… and of redistributing national resources through social spending for the common good,” concludes Dr. Bezruchka. (ANI)

Tata Motors suffer Q1 loss, but confident of improvement

September 1, 2009 By admin Leave a Comment

Mumbai, Sep 1 (ANI): Tata Motors, India’s largest vehicle maker have posted a consolidated loss for its fiscal first quarter, but remained confident about the prospects of its loss-making Jaguar and Land Rover (JLR) unit.

This was disclosed by the C Ramakrishnan, Chief Financial Officer at a press conference that was also addressed by Ravi Kant, Vice Chairman and Prakash Telang, Managing Director of the company here on Monday.

The company, which controls about 60 percent of the world’s fifth-biggest truck and bus market, said that increased borrowing to support investments and new product development caused an increase in depreciation and interest costs.

It said JLR unit’s sales fell about 52 percent in the quarter from a year ago due to adverse global market conditions.

The company is eyeing some support from the commercial banks to meet the crisis.

“We are working on to tie up our working facilities with commercial banks for Jaguar and Land Rover (JLR)…this has been put in place, some work is still going on which would be finalise in next few weeks,” said Ramakrishnan.

The company reported 3.29 billion rupees consolidated loss for April-June.

In the year-ago quarter, Tata Motors posted a net profit of 7.2 billion rupees, but said the figures were not comparable as the previous period contained JLR numbers only for June 2-30. Tata said JLR made a loss before tax of 62 million pounds during the fiscal first quarter. JLR sold 35,900 units during the quarter, up from 32,600 in the March quarter.

In July, Tata Motors reported a standalone net profit of 5.14 billion rupees for its Indian operations. But officials hoped that market would recover despite a weal monsoon.

“I can say that things would have been better, but the monsoon has not been so good that caution optimism but we still believe that things would be slightly better in coming time,” said Prakash Telang, Managing Director, Tata Motors.

Auto sales in India have been rising on an improving economy, easier finance and new launches, including Tata Motor’s Nano, the world’s cheapest car, which hit the roads in July.

The company’s consolidated debt at the end of June stood at 240 billion rupees. The company has said it would look at capital raising at an appropriate time to deleverage its balance sheet. (ANI)

Obese kids aged 12 showing early signs of heart disease: EU study

September 1, 2009 By admin Leave a Comment

London, Sept 1 (ANI): Overweight and obese kids as young as 12 are showing early signs of heart disease, warn Spanish researchers.

During a study, scientists in Barcelona analysed 80 obese and overweight kids with an average age of 12 and compared them with 60 lean youngsters.

They found that larger kids had higher cholesterol and blood pressure, as well as more signs of pre-diabetes.

The researchers are now looking into “endothelial dysfunction” – a thickening of the arteries associated with heart problems.

By studying how easily the forearm relaxes, scientists are able to monitor the degree of the dysfunction.

They discovered the overweight and obese children had a similar level of the condition to adults with chronic heart disease.

“Endothelium-dependent relaxation of forearm arteries is already impaired by the same as in adults with chronic heart failure, and this in our 12-year old obese children,” the Scotsman quoted the researchers as saying.

“Primary or secondary prevention strategies starting early in childhood should aim at reversing current increase in childhood obesity.

“These strategies can be initiated at home and in preschool institutions, schools or after-school care services to influence diet and physical activity in the entire children population. However, further research needs to explore the most effective strategies to prevent and treat obesity.

“Already in early childhood, overweight and obesity are associated with the risk factors for the development of cardiovascular diseases like diabetes, high blood pressure or high cholesterol levels,” they added.

The findings were presented at European Society of Cardiology. (ANI)

Carbon monoxide exposure may up heart problem risk for the elderly

September 1, 2009 By admin Leave a Comment

Washington, Sep 1 (ANI): Carbon monoxide exposure has been found to elevate the risk of hospitalisation for the elderly with heart problems in an American study.

The nationwide study of 126 urban communities has shown that an increase in carbon monoxide of 1 part per million in the maximum daily one-hour exposure is linked with a 0.96 percent increase in the risk of hospitalisation from cardiovascular disease among people over the age of 65.

The connection remains even when carbon monoxide levels are less than 1 part per million, which is well below the Environmental Protection Agency’s (EPA) National Ambient Air Quality Standard of 35 parts per million.

The finding has indicated that an under-recognized health risk to seniors.

Presently, the EPA is evaluating the scientific evidence on the link between carbon monoxide and health to determine whether the health-based standard should be modified.

“This evidence indicates that exposure to current carbon monoxide levels may still pose a public health threat. Higher levels of carbon monoxide were associated with higher risk of hospitalisations for cardiovascular heart disease,” said Michelle Bell, the study’s lead investigator.

Working in collaboration with experts from the Johns Hopkins Bloomberg School of Public Health and the University of Southern California’s Keck School of Medicine, Bell analysed hospital records for 9.3 million Medicare recipients and data on air pollution levels and weather, gathered between 1999 and 2005.

The analysis considered the health effects of other traffic-related pollutants, including nitrogen dioxide, fine particles, and elemental carbon.

“We found a positive and statistically significant association between same-day carbon monoxide levels and an increased risk of hospitalisation for cardiovascular disease in general, as well as for multiple, specific cardiovascular disease outcomes, including ischemic heart disease, heart rhythm disturbances, heart failure and cerebrovascular disease,” said Bell.

Carbon monoxide is a tasteless, odourless gas that is a component of automobile exhaust.

The researchers stressed the need for additional research to investigate whether carbon monoxide or a combination of it and other traffic-related pollutants could result in increased cardiovascular hospitalisations in the elderly.

Their most recent findings have been detailed in a research article published in Circulation: Journal of the American Heart Association. (ANI)

CCEA reviews prices of essential commodities

September 1, 2009 By admin Leave a Comment

New Delhi, Aug 31(ANI): The Cabinet Committee on Economic Affairs (CCEA) on Monday reviewed the prices of essential commodities and observed that the major areas of concern were prices of pulses and sugar.

The CCEA has said that several steps have been taken to increase the availability of pulses and sugar, which would help in controlling the price increase.

The need to enforce stock limits, carry out de-hoarding operations and use the powers available under the Essential Commodities Act and the Prevention of Black-marketing and Maintenance of Supplies of Essential Commodities Act have also been emphasised. (ANI)

Beefed-up diets of Asia’s middle class may lead to chronic food shortages

August 30, 2009 By admin Leave a Comment

Washington, August 30 (ANI): Scientists have said that the beefed-up diets of Asia’s expanding middle class could lead to chronic food shortages for the water-stressed region.

According to a report in National Geographic News, the threat was highlighted in a study by the International Water Management Institute (IWMI) and the UN Food and Agriculture Organization (FAO), which estimate that Asian demand for food and livestock fodder will double in 40 years.
Asia’s growing economy and appetite for meat will require a radical overhaul of farmland irrigation to feed a population expected to swell to 1.4 billion by 2050, scientists warned at Stockholm’s World Water Week recently.
At current crop yields, East Asia would need 47 percent more irrigated farmland and to find 70 percent more water, the study found.
South Asia would have to expand its irrigated crop areas by 30 percent and increase water use by 57 percent.
Given existing agriculture pressure on water resources and territory, that’s an impossible scenario, according to the study authors.

Scientists urge modernization of existing large-scale irrigation systems, most of which were installed in the 1970s and 1980s.
It’s estimated that India, the world’s largest consumer of underground water, has 19 million unregulated groundwater pumps.
Groundwater in northern India is receding by as much as a foot (0.3 meter) a year due to rampant water extraction, most of it for crop irrigation, according to a study.
More than 109 cubic kilometres of groundwater were drained from the region between 2002 and 2008, according to the satellite image-based study led by scientists with NASA’s Goddard Space Flight Center.
“Governments’ inability to regulate this practice is giving rise to scary scenarios of groundwater over-exploitation, which could lead to regional food crises and widespread social unrest,” said Tushaar Shah of IWMI.

As for China, the country’s per capita “water footprint” for food production has almost doubled since 1985, according to Junguo Liu of the Beijing Forestry University.
“A switch from traditional rice and noodles to a meatier diet is behind the change,” Liu said. “Changes in food consumption are the major cause of worsening water scarcity in China,” he added.
Total water requirements for food production in China are predicted to rise by 40 to 50 percent in the next 30 years, he further added.
“Where do you get such a big amount of water? It is a really big question and a big challenge,” he said.
“If other developing countries follow China toward a Western diet, the global water shortage becomes even more serious,” he added. (ANI)

Polluted Sutlaj River water causing skin disease

August 30, 2009 By admin Leave a Comment

Ropar (Punjab), Aug 30 (ANI): Hazardous industrial waste seeping into the Sutlaj River flowing through Ropar District in Punjab has contaminated the water to the extent that people are getting skin diseases and stomach ailments.

Environmentalists blamed cement and thermal factories along the Sutlaj River for polluting the water, apart from effluents released into the river from factories in Himachal Pradesh.

“The industrial effluents released from a thermal plant near Ghanoli in Ropar is going into the river and percolating into the ground water. When people draw the water from a hand pump or a well, it has lot of sulphur and other chemicals,” said Jaswant Singh, an environmentalist in Ropar.

People living in about 20 villages mainly use ground water, which has a high sulphur content. They say the water drawn from a well or hand pump looks yellow and tastes weird and it is inflicting skin diseases.

“We can’t work in this water for long. If you do, you get various skin diseases and it also upsets the stomach,” said Jaswant Singh, a patient.

There has been a sudden increase in the number of people visiting health centres due to various water-borne diseases.

“Contaminated water is the main problem here. We are getting lot of patients with skin disease, boils, diarrhea and cholera,” said Amandeep Kaur, a pharmacist at a local health centre.
