Acupressure seen to calm children before surgery

Tuesday, September 30th, 2008

Acupressure helps calm anxious children right before they get anesthesia for surgery, without the nausea and other side-effects caused by sedatives, U.S. researchers reported on Tuesday.

Taping an acupressure bead between the eyebrows reduced anxiety noticeably in the children, compared to a similar sham treatment, Dr. Zeev Kain of the University of California Irvine and colleagues reported.

Anxiety in children before surgery is bad because of the emotional toll on the child and parents, and this anxiety can lead to prolonged recovery and the increased use of analgesics for postoperative pain,” Kain said in a statement.

“What’s great about the use of acupressure is that it costs very little and has no side effects.”

Acupressure and acupuncture both are based on the theory of lines of energy running through the body. With acupressure, a fingertip or a bead is used to press a specific pressure point, while needles are used in acupuncture.

Several studies have shown both treatments may stimulate the release of hormones known as endorphins, which can relieve stress, pain and nausea.

Kain’s team tested 52 children aged 8 to 17 who were about to have stomach surgery. Half got a bead taped to the Extra-1 acupoint — one of the points used to reduce stress in both acupuncture and acupressure therapy.

The other half got a similar patch on a spot above the left eyebrow that had no reported clinical effects.

After half an hour, the treated children were less anxious, while the young patients who got the sham treatment were clearly more anxious, Kain’s team reported in the journal Anesthesia & Analgesia.

“As anesthesiologists, we need to look at all therapeutic opportunities to make the surgical process less stressful for all patients,” Kain said. “We can’t assume that Western medical approaches are the only viable ones, and we have an obligation to look at integrative treatments like acupressure

Campus green spaces improve students’ quality of life, learning

Tuesday, September 30th, 2008

The more green spaces are there in a college campus, the better satisfied are students with their lives, says a new study.According to the research, campus green spaces can help students feel better about life and improve learning.

In the study led by L. McFarland, a graduate student in the Department of Agriculture at Texas State University, the researchers surveyed 373 undergraduates at the San Marcos campus.

The respondents were then ranked as “low users”, “medium users”, or “high users” of campus green spaces.

More than 90 percent of respondents were ranked as either high or medium users of green space. The students were also asked to rate their perception of quality of life.

A mean score of more than four (on a scale of 1 to 5) indicated that most students rated their quality of life as positive.

According to McFarland, the researchers were able to make a “statistically significant” correlation between green space users and those who gave a high rating to their quality of life.

“These findings indicated that those (students) who used campus green spaces more frequently rated their overall quality of life higher when compared with students who used the campus green spaces and arboretum less frequently”, said McFarland.

Moreover, students who spent greater time in green space also rated their cognitive ability to apply knowledge learned in college as higher compared to those students who spent less time.

The results are published in the April 2008 issue of the American Society for Horticultural Science’s journal, HortTechnology.

Snag in Adobe s/w allows free downloads

Tuesday, September 30th, 2008

A security hole in Adobe Systems Inc software, used to distribute movies and TV shows over the Internet, is giving users free access to record and copy from Amazon.com Inc’s video streaming service.

The problem exposes online video content to the rampant piracy that plagued the music industry during the Napster era and is undermining efforts by retailers, movie studios and television networks to cash in on a huge Web audience.

“It’s a fundamental flaw in the Adobe design. This was designed stupidly,” said Bruce Schneier, a security expert who is also the chief security technology officer at British Telecom.

The flaw rests in Adobe’s Flash video servers that are connected to the company’s players installed in nearly all of the world’s Web-connected computers.

The software doesn’t encrypt online content, but only orders sent to a video player such as start and stop play. To boost download speeds, Adobe dropped a stringent security feature that protects the connection between the Adobe software and its players.

“Adobe is committed to the security of all of our products, from our players to our server software. Adobe invests a considerable amount of ongoing effort to help protect users from potential vulnerabilities,” it said in a statement.

Adobe said it issued a security bulletin earlier this month about how best to protect online content and called on its customers to couple its software security with a feature that verifies the validity of its video player.

An Amazon spokesman said content on the company’s Video On Demand service, which offers as many as 40,000 movies and TV shows on its Web site, cannot be pirated using video stream catching software.

However, in tests, at least one program to record online video, the Replay Media Catcher from Applian Technologies, recorded movies from Amazon and other sites that use Adobe’s encryption technology together with its video player verification.

“Adobe’s (stream) is not really encrypted,” said Applian CEO Bill Dettering. “One of the downfalls with how they have architected the software is that people can capture the streams. I fully expect them to do something more robust in the near future.”

How it works

The free demo version of Replay Media Catcher allows anyone to watch 75 percent of anything recorded and 100 percent of YouTube videos. For USD a user can watch everything recorded.

One Web site — www.tvadfree.com — explains step-by-step how to use the video stream catching software.

Amazon.com’s Adobe-powered Video On Demand service allows viewers to watch the first two minutes of a movie or TV show for free. It charges up to $3.99 to rent a movie for 24 hours and up to USD 14.99 to download a movie permanently. Amazon starts to stream the entire movie during the free preview — even though it pauses the video on the Web browser after the first two minutes — so that users can start watching the rest of the video right away once they pay.

“It’s the traditional trade-off, convenience on the one hand and security on the other,” said Ray Valdes, analyst at research group Gartner.

However, even if a user doesn’t pay, the stream still sends the movie to the video catching software, but not the browser.

Amazon’s Video On Demand is the Web retailer’s answer to declining sales of packaged movies and TV shows and the growth in demand for digital content that can be viewed and stored on the Internet.

Unlike Amazon, videos from Hulu.com, NBC.com and CBS.com are already free although the TV programs are interrupted by commercials. However, the stream catching software separates the commercials and the program into two separate folders, so people can keep the programs without the advertising.

Hulu.com, a video Web site owned by News Corp’s Fox network and General Electric’s NBC Universal, was the big networks’ answer to YouTube, the popular video-sharing Web site where many users began uploading TV shows and other content owned by media companies.

The networks scrambled to post videos on their own sites in a bid to capture another stream of advertising revenue from a growing audience, but they have struggled with how best to show commercials which fund the programing when played on the Web.

YouTube, which started the online video boom before being bought by Google Inc for USD 1.65 billion in November 2006, has also struggled to cash in on its popularity even though its user base continues to mushroom.

Destroying Business Models

One possible solution would be to protect the video with a digital rights management (DRM) system. A Seattle-based company called Widevine Technologies has a DRM system that can encrypt online videos using Flash.

“The fundamental problem here is that Adobe’s lack of technology is not allowing the business models to be preserved,” said Widevine Chief Executive Brian Baker.

The lack of content protection, according to Baker, threatens all the business models used today to fund video on the Web.

Apple Inc, which sells movies and television shows at its online iTunes store, uses its own DRM technology called FairPlay, but it only works for video bought on iTunes.

Forrester analyst James McQuivey said he doesn’t believe the video stream catching technology will entirely derail the advertising-supported business model used by the networks for online video.

“It’s too complicated for most users,” said McQuivey, noting that file-sharing services like BitTorrent already exist but only a small percentage of people use them.

“People want something easy to find and easy to use.”

Smoking scenes in movies has Bollywood divided

Tuesday, September 30th, 2008

From Oct 2, the government will introduce its new no-smoking policy. Most Bollywood personalities like Saif Ali Khan, Shabana Azmi and Akhshaye Khanna welcome this move, but some feel it would be unfair to ban smoking in movies.Saif Ali Khan: Smoking should be banned indoors in public. But why ban it on screen? It’s just acting and everyone knows it.

Akshaye Khanna: Smoking should be banned in public places, but not in movies.

Shabana Azmi: Yes, smoking should be banned in public spaces, but not on screen. Because smoking could reveal a lot about a character especially if it’s a woman. And to me endorsement of cigarettes by celebrities is a big no. But banning isn’t the solution. We’ve to create enough awareness so that people would want to give it up on their own, as was the case in the US. Children should be so aware of the damage done by smoking that they should stop their parents from smoking.

Hema Malini: Yes, smoking should definitely be banned in both - public places and films.

Rakhi Sawant: I agree with Hemaji. Smoking should be banned, that’s all.

Irrfan Khan: In public places, yes! Smoking must be banned since it’s one of the primary sources of air pollution.

Lilette Dubey: I’m against banning smoking in open public places. To smoke is a personal choice, and we are a democracy. As long as we don’t offend someone by polluting his or her space there’s no harm in smoking. However, on screen it’s a different matter. There’s a huge impressionable audience. So smoking should definitely be banned on screen. If screen icons are shown smoking, it immediately becomes cool. We’ve to accept the fact that films wield a great influence.

Sudhir Mishra: I’ve just managed to quit smoking. But I think there should be enclosed spaces in public places for smokers.

Neil Mathur: There should be areas marked for smokers in public. But I see no reason to ban smoking from screen. If a script demands a character to smoke, why not? So many vices are depicted. Do we ban all of them?

Arshad Warsi: I can understand the need to ban smoking in public places. But ban smoking in films? No way! And if the government wants us to do what they want, why don’t they fulfil at least 10 percent of their promises?

Amrita Arora: Yeah, it’s better to ban smoking in public and in movies. It’s only fair to people who don’t smoke… not to mention the lungs of those who do.

Malaika Arora: It should be banned in public places. But on screen? I really don’t see the purpose.

Javed Akhtar: Public places? Yes, smoking should be banned. On the screen? No!

Anurag Kashyap: Banning smoking in public places is fine. Ban it by all means. But not in films. For that you’ll have to ban cigarettes altogether.

Kangana Ranaut: No I don’t think smoking should be banned. But no one should smoke in front of babies. As for the movies, we should be allowed to do what we want to within limits. Nothing should come in the way of our creativity. Smoking is not the only thing that’s injurious to health. What about noise pollution in pubs? We all have to leave our bodies one day anyway. Some sooner than others. No worries.

Prakash Jha: No I don’t think smoking should be banned, but definitely restricted and discouraged. And the same goes for the screen. Smoking should never be glorified. I am in principle against any kind of ban.

Madhur Bhandarkar: Of course, smoking should be banned in public places. Smoking is injurious to everyone especially children. But on screen I say no, no ban. That’s just acting.

Sex steroid DHEA does not help post-menopausal women

Tuesday, September 30th, 2008

A new trial by Monash University researchers has found that the much-hyped sex steroid DHEA does not provide any significant benefits to post-menopausal women.The 12-month trial, by associate professor Susan Davis and PhD student Mary Panjari, investigated the impact of DHEA or dehydroexpiandrosterone, on the sexual desire, menopausal symptoms, mood and well-being of 93 postmenopausal women.

‘The hype surrounding DHEA far exceeds any health benefits,’ Susan Davis said, according to a release of Monash University.

‘DHEA occurs naturally in the body and can also be taken in supplement form. It is increasingly prescribed to post-menopausal women to help improve their wellbeing and boost libido. However, our study showed no significant improvement in any of these areas.’

DHEA is a sex steroid or hormone secreted by the adrenal glands. It is the most abundant hormone in women aged in their mid-20s but levels decline dramatically from this age and are almost halved in many women by the age of 40 years.

Co-investigator of the Women’s Health Program study, Robin Bell said between 30 and 40 per cent of post-menopausal women report low sexual desire. About 50 per cent of women experience significant menopausal symptoms, the most common of which is hot flushes, and about 35 per cent of women experience moderate symptoms.

‘DHEA is converted to both oestrogen and testosterone in the body, so theoretically it has the potential to reduce hot flushes and other symptoms and increase a woman’s sexual function and general well-being. It was thought that by restoring the steroid levels to those found in younger women, that an anti-ageing effect would result in an all-round improvement to well-being. However, in our study none of these effects were achieved,’ Bell said.

Side effects reported in the study included increased acne, excess body hair, and a small reduction in HDL cholesterol.

Bell said based on their research findings, it was safe to say that women who were taking DHEA were receiving very little benefit — if any at all.

‘While we found no immediate safety risks, the claims to fame of DHEA are simply not supported by the science,’ Bell said.

Mars lander finds minerals suggesting past water

Tuesday, September 30th, 2008

NASA’s Phoenix spacecraft has discovered evidence of past water at its Martian landing site and spotted falling snow for the first time, scientists reported Monday. Soil experiments revealed the presence of two minerals known to be formed in liquid water. Scientists identified the minerals as calcium carbonate, found in limestone and chalk, and sheet silicate.

But exactly how that happened remains a mystery.

“It’s really kind of all up in the air,” said William Boynton, a mission scientist at the University of Arizona at Tucson.

A laser aboard the Phoenix recently detected snow falling from clouds more than two miles above its home in the northern arctic plains. The snow disappeared before reaching the ground.

Phoenix landed in the Martian arctic plains in May on a three-month mission to study whether the environment could be friendly to microbial life. One of its biggest discoveries so far is confirming the presence of ice on the planet.

Scientists long suspected frozen water was buried in the northern plains based on measurements from an orbiting spacecraft. The lander also found that the soil was slightly alkaline and contained important nutrients and minerals.

Scientists think there could have been standing water at the site in the past or the ice could have melted and interacted with the minerals.

“Is this a habitable zone on Mars? I think we’re approaching that hypothesis,” said chief scientist Peter Smith of the University of Arizona. “We understand, though, that Mars has many surprises for us and we have not finished our investigation.”

Mars today is frigid and dry with no sign of water on the surface, but researchers believe the planet once was warmer and wetter.

NASA extended the three-month mission through the end of the year if Phoenix can survive that long. With summer waning, less sunlight is reaching the spacecraft’s solar panels.

Phoenix will be out of touch with ground controllers briefly in November when the sun is between Earth and Mars, blocking communications.

Scientists are racing to use the remaining four of Phoenix’s eight tiny test ovens before the lander dies. The ovens are designed to sniff for traces of organic, or carbon-based compounds, that are considered the building blocks of life. Experiments so far has failed to turn up definitive evidence of organics.

Australian woman unable to open eyes three days a week: report

Monday, September 29th, 2008

An Australian woman is blind three days out of every six because her eyes involuntarily shut and she can’t open them — a mysterious medical condition that has puzzled doctors, a report said Sunday.

Natalie Adler, who experts believe may be the only person in the world with this condition, said she has had this medical predicament since she was 17.

“I woke one Sunday and my eyes were swollen. It was the day before an English exam,” the 21-year-old told Melbourne’s Herald Sun.

“My eyes started closing intermittently, really randomly, but within a few weeks they were closing for three days (at a time),” said Adler.

Doctors from the Royal Victoria Eye and Ear Hospital said Adler’s condition was baffling.

“She’s a one-off and we don’t have a diagnosis,” said Professor Justin O’Day of the hospital’s neuro-ophthalmology department.

“It’s unusual to see somebody with this degree of spasming and eyelid closure, especially at this age. There is no known cause.”

O’Day said the medical condition blepharospasm, which causes an involuntary closing of the eyes, could be used as a reference but that it did not explain why Adler’s eyes closed according to a routine.

When Adler’s eyes are closed, she can’t see at all except through a small slit in her left eye. On the days when they are open, she can see clearly but her left eyelid droops.

For almost two years, doctors treated her by injecting Botox around her eyes, allowing her to see for five days out of six.

But the treatment no longer works for Adler, who also suffers from fatigue and nausea, and she is now hopeful that electrical stimulation tests around her eyes might help.

Adler plans her life around her condition, but still misses some important dates. “On my 18th birthday, my eyes were closed, but on my 21st they were open, so I had a party,” she said.

“Not being able to go to the football or seeing my friends as much is what I miss the most.”

SpaceX launches 1st commercial rocket into orbit

Monday, September 29th, 2008

An Internet entrepreneur’s latest effort to make space launch more affordable paid off Sunday when his commercial rocket, carrying a dummy payload, was lofted into orbit from the South Pacific.

It was the fourth attempt by Space Exploration Technologies, or SpaceX, to launch its two-stage Falcon 1 rocket into orbit.

“Fourth time’s a charm,” said Elon Musk, the multimillionaire who started up SpaceX after making his fortune as the co-founder of PayPal Inc., the electronic payment system.

The rocket carried a 364-pound dummy payload designed and built by SpaceX for the launch.

“This really means a lot,” Musk told a crowd of whooping employees. “There’s only a handful of countries on Earth that have done this. It’s usually a country thing, not a company thing. We did it.”

Musk pledged to continue getting rockets into orbit, saying the company has resolved design issues that plagued previous attempts.

Last month, SpaceX lost three government satellites and human ashes including the remains of astronaut Gordon Cooper and “Star Trek” actor James Doohan after its third rocket was lost en route to space. The company blamed a timing error for the failure that caused the rocket’s first stage to bump into the second stage after separation.

SpaceX’s maiden launch in 2006 failed because of a fuel line leak. Last year, another rocket reached about 180 miles above Earth, but its second stage prematurely shut off.

Falcon 1, a 70-foot-long rocket powered by liquid oxygen and kerosene, is the first in a family of low-cost launch vehicles priced at $7.9 million each.

Besides the Falcon 1, SpaceX is developing for NASA a larger launch vehicle, Falcon 9, capable of flying to the international space station when the current space shuttle fleet retires in 2010.

A toast to a decade

Monday, September 29th, 2008

Some posed happily, others tried to dodge the camera, still others stood close to those sought out by photographers. Lots of well-known faces in the city’s social circuit were seen at the party hosted at Le Meridien by Amway India to mark the completion of 10 years in the business.

William S Pinckney, managing director and CEO, stood at the door throughout, welcoming and seeing guests off with a “I’m glad everyone came on time.” Present there were Christian M Schlaga, minister and deputy chief of mission, embassy of Germany; Vijay Jolly, BJP MLA, with wife Rashmi; Manoj Arora, treasurer, Delhi Study Group, with wife Alka; Gabriele Annis, first secretary, embassy of Italy with Graziella; Madhav Nepal; Rajeev Shukla; Pradeep Jain, chairman of Parsvnath Developers; and Malaysian high commissioner Dato’ Tan Seng Sung.

‘Eagle Eye’ soars to No. 1 at box office with $29M, CA

Monday, September 29th, 2008

Shia LaBeouf’s conspiracy thriller “Eagle Eye” debuted at the top of the weekend box office with $29.2 million, according to studio estimates Sunday. The Paramount-DreamWorks release was the second No. 1 premiere for LaBeouf and director D.J. Caruso, who also teamed on 2007’s hit “Disturbia.” Opening in second-place with $13.6 million was another reunion, the Warner Bros.

romantic drama “Nights in Rodanthe,” featuring “The Cotton Club” and “Unfaithful” co-stars Richard Gere and Diane Lane. The previous weekend’s top flick, Sony’s thriller “Lakeview Terrace,” slipped to No.

3 with $7 million, raising its 10-day total to $25.7 million. The Samuel Goldwyn release “Fireproof,” a Christian drama starring Kirk Cameron as a firefighter who turns to God to help save his marriage, premiered in fourth-place with $6.5 million.

“Eagle Eye” helped pull Hollywood out of the box-office doldrums that have lingered the last two months. The top-12 movies took in $87.8 million, up 15 percent from the same weekend last year.

“You put a summer-style movie in the heart of the fall, and you can take advantage of the marketplace,” said Paul Dergarabedian, president of box-office tracker Media By Numbers. Spike Lee’s World War II drama “Miracle at St.

Anna” opened weakly with $3.5 million, coming in at No. 9.

The Disney release features Derek Luke in a saga of four soldiers from an all-black unit stuck behind enemy lines in Italy. Two other movies, Fox Searchlight’s “Choke” and Lionsgate’s “The Lucky Ones,” opened in narrower release of about 400 theaters each, compared to 3,510 cinemas for “Eagle Eye.

” “Choke,” starring Sam Rockwell and Anjelica Huston in a quirky tale of a sex addict who feigns choking in restaurants to get money for his mom’s psychiatric care, opened outside the top-10 with $1.3 million. “The Lucky Ones,” a road trip tale among three Iraq War veterans (Tim Robbins, Michael Pena and Rachel McAdams), bombed with just $208,000.

“Eagle Eye” stars LaBeouf and Michelle Monaghan as strangers hurled together in an escalating series of politically motivated adventures, their lives controlled by a mysterious female voice directing their actions through technology. “The conceit of the film is intriguing to all,” said DreamWorks spokesman Chip Sullivan.

“Between GPS, employee codes, bank PIN numbers, this could conceivably be within the realm of possibility within a few years.” The movie secures LaBeouf’s position as a steady box-office draw.

His other credits include “Indiana Jones and the Kingdom of the Crystal Skull” and “Transformers,” along with the latter’s upcoming sequel. “Nights in Rodanthe” features Gere and Lane as strangers who fall for each other over a weekend at a secluded inn as a hurricane approaches.

The romance made for good counterprogramming to the action-oriented “Eagle Eye,” said Warner Bros. general sales manager Jeff Goldstein.

Female movie-goers made up three-fourths of the audience for “Nights in Rodanthe,” he said. Estimated ticket sales for Friday through Sunday at U.S. and Canadian theaters, according to Media By Numbers LLC. Final figures will be released Monday.

1. “Eagle Eye,” $29.2 million.

2. “Nights in Rodanthe,” $13.6 million.

3. “Lakeview Terrace,” $7 million.

4. “Fireproof,” $6.5 million.

5. “Burn After Reading,” $6.2 million.

6. “Igor,” $5.5 million.

7. “Righteous Kill,” $3.803 million.

8. “My Best Friend’s Girl,” $3.8 million.

9. “Miracle at St.

Anna,” $3.5 million. 10.

“Tyler Perry’s the Family That Preys,” $3.2 million. ___ On the Net: http://www.
