Place / Kuakata Sea Beach in Bangladesh
« on: July 10, 2013, 08:52:58 PM »
FASCINATING KUAKATA

Cooing Kuakata, the lowland lass of Latachapli in the sea-facing south of Bangladesh is 70 km. from Patuakhali District Headquarters and 320 km. from the Capital City of Dhaka. Here on the Bay, nature left to nature is the up and coming tourist hamlet of Kuakata with cool and kind holidaying kiss.
kuakata sea beach beautiful bangladesh
Fascinating name Kua (well), Kata (dug) was perhaps given to it by the earliest Rakhyne settlers from Kingdom of Arakan who landmarked the place by digging a well. Fabled curative qualities of well-waters of Kuakata is still a matter of “willing suspension of disbelief”. Fascinating still more is the sight of the sun at dawn rising from the depths of the sea and sinking into the same at dusk which can be glanced from the same point.

TOURIST ATTRACTIONS

Heritage/Culture / Ahsan Manzil
« on: July 10, 2013, 08:51:36 PM »
Built in 1872 and standing on the river Buriganga, this stately building offers the visitors a feeling of the life-style of the Nawabs of Dhaka. Sometimes known as the Pink Palace, this building now houses a splendid museum. Basically, it was the residence of the Nawabs. Nawab Abdul Gani renovated this building in the year 1872  and named it after his son Khaza Ahasanullah. On the bank of river Buriganga in Dhaka the Pink majestic, Ahsan Manjil has been renovated and turned into a museum recently. It is an epitome of the nation’s rich cultural heritage.Based on an access of 1 meter, two-story alcazar measures 125.4m by 28.75m. The acme of the arena attic is 5 meters, and the aboriginal attic of 5.8 meters. There are columns of the acme of the arena floor, both arctic and south ancillary of the castle. A ample accessible stairway bottomward from the south portico, boarded the river through the advanced yard.
Ahsan Manzil information,Dhaka

Ahsan Manzil, an architectural gem, is attestant to abounding actual contest of Bangladesh. The aftermost allotment of the 19th aeon until the aboriginal years of Pakistan, Muslim leaders of East Bengal emerged from the palace. Nawabs of Dhaka acclimated to do business actuality in cloister as arch of the Panchayet (village council) every day. Abounding anti-Congress affairs were captivated in the Nawab of Ahsanullah condescension, a allegiant apostle of the Muslim identity. Almost all the viceroys, governors and abettor governors of British India visited Dhaka spent some time at the Ahsan Manzil.
Constraction of the architecture was started in 1859 and ends at 1872. Abdul Ghani called it Ahsan Manzil afterwards his son Nawab Khwaja Ahsanullah. The anew congenital alcazar aboriginal came to be accepted as the Rang Mahal. On April 7, 1888, a tornado acquired astringent accident to Ahsan Manzil — Andar Mahal, the earlier allotment of the palace, was absolutely devastated. During the about-face of the Andar Mahal a acceptable allotment of the alcazar was overhauled and repaired, and the admirable arch of the present Rang Mahal was added. Ahsan Manzil was afresh damaged by an convulsion in 12 June 1897 and afresh repaired by the Nawab Ahsanullah.
Location:
Ahsan Manzil is Kumartoli, Shakara Waiz Ghat Bazar Old Dhaka. And ‘Sutrapur Thana under Dhaka City Corporation. Ahsan Manzil palace was the residence of the Nawabs but is now a museum. An influential family in the old Dhaka Nawabs lived for many years. They built a magnificent building, a living wage. Ahsan Manzil is one of them.

Person / ASCLEPIUS
« on: July 10, 2013, 11:38:49 AM »
In the Iliad, the writer Homer mentions Asclepius only asa skillful physician and the father of two Greek doctors at Troy, Machaon and Podalirius. In later times, however, he was honoured as a hero, and eventually worshiped as a god. Asclepius (Greek: Asklepios, Latin: Aesculapius), the son of Apollo (god of healing, truth, and prophecy) and the mortal princess Coronis, became the Greco-Roman god of medicine. Legend has it that the Centaur Chiron, who was famous for his wisdom and knowledge of medicine, taught Asclepius the art of healing. At length Zeus, the king of the gods, afraid that Asclepius might render all men immortal, slew him with a thunderbolt. Apollo slew
the Cyclopes who had made the thunderbolt and was then forced by Zeus to serve Admetus.
Asclepius’s cult began in Thessaly but spread to many parts of Greece. Because it was supposed that Asclepius effected cures of the sick in dreams, the practice of sleeping in his temples in Epidaurus in South Greece became common. This practice is often described as Asclepian incubation. In 293 BCE his cult spread to Rome, where he was worshiped as Aesculapius.
Asclepius was frequently represented standing, dressed in a long cloak, with bare breast; his usual attribute was a staff with a serpent coiled around it. This staff is the only true symbol of medicine. A similar but unrelated emblem, the caduceus, with its winged staff and intertwined serpents, is frequently used as a medical emblem but is without medical relevance since it represents the magic wand of Hermes, or Mercury, the messenger of the gods and the patron of trade. However, its similarity to the staff of Asclepius resulted in modern times in the adoption of the caduceus as a symbol of the physician and as the emblem of the U.S. Army Medical Corp. The plant genus Asclepias, which contains various species of milkweed, was named for Asclepius. Many of these plants possess some degree of medicinal value.

Solar / NASA telescope to probe solar mystery
« on: July 10, 2013, 11:22:56 AM »
The study is far from academic. Solar activity directly impacts Earth's climate and the space environment beyond the planet's atmosphere. Solar storms can knock out power grids, disrupt radio signals and interfere with communications, navigation and other satellites in orbit.

"We live in a very complex society and the sun has a role to play in it," said physicist Alan Title, with Lockheed Martin Space Systems Advanced Technology Center in Palo Alto, California, which designed and built the telescope.

Scientists have been trying to unravel the mechanisms that drive the sun for decades but one fundamental mystery endures: How it manages to release energy from its relatively cool, 10,000 degree Fahrenheit (5,500 degree Celsius) surface into an atmosphere that can reach up to 5 million degrees Fahrenheit (2.8 million Celsius).

At its core, the sun is essentially a giant fusion engine that melds hydrogen atoms into helium. As expected, temperatures cool as energy travels outward through the layers. But then in the lower atmosphere, known as the chromosphere, temperatures heat up again.

Pictures and data relayed by the Interface Region Imaging Spectrograph, or IRIS, telescope may finally provide some answers about how that happens.

The 4-foot (1.2-meter) long, 450-pound (204-kg) observatory will be watching the sun from a vantage point about 400 miles above Earth. It is designed to capture detailed images of light moving from the sun's surface, known as the photosphere, into the chromosphere. Temperatures peak in the sun's outer atmosphere, the corona.

All that energy fuels a continuous release of charged particles from the sun into what is known as the solar wind, a pressure bubble that fills and defines the boundaries of the solar system.

"Every time we look at the sun in more detail, it opens up a new window for us," said Jeffrey Newmark, IRIS program scientist at NASA headquarters in Washington, DC.

The telescope was launched aboard an Orbital Sciences Corp Pegasus rocket at 10:27pm EDT Thursday (0227 GMT Friday). Pegasus is an air-launched system that is carried aloft by a modified L-1011 aircraft that took off from Vandenberg Air Force Base in California about 57 minutes before launch.

The rocket was released from beneath the belly of the plane at an altitude of about 39,000 feet before it ignited to carry the telescope into orbit.

IRIS, which cost about $145 million including the launch service, is designed to last for two years.

Solar / Solar plane on journey across US
« on: July 10, 2013, 11:20:32 AM »
The Solar Impulse landed at Dulles International Airport outside Washington at 12:15 a.m. EDT, organizers said in a statement. It will remain in the US capital until it takes off for New York in early July for the last leg of its historic trip.

If the spindly experimental aircraft completes the journey as planned, it will be the first solar-powered plane capable of operating day and night to fly across the United States.

"It proves the reliability and potential of clean technologies, and this is crucial in pushing our message forward," Swiss pilot Bertrand Piccard said in the statement. Piccard founded the Solar Impulse project with fellow pilot Andre Borschberg.

With the wingspan of a jumbo jet and the weight of a small car, the Solar Impulse is a test model for a more advanced aircraft the team plans to build to fly around the world in 2015.

The plane completed the first leg of the journey from San Francisco to Phoenix in early May and flew later that month from Phoenix to Dallas.

In early June, the Solar Impulse made the trip from Dallas to St. Louis. It flew to Washington in nearly 30 hours of flying over two days.

The project began in 2003 with a 10-year budget of 90 million euros ($112 million). It has involved engineers from Swiss escalator maker Schindler and research aid from Belgian chemicals group Solvay.

The plane made its first intercontinental flight, from Spain to Morocco, in June 2012.

The aircraft is propelled by energy collected from 12,000 solar cells in its wings that simultaneously recharge batteries for night use.

Cancer / Tamoxifen for fight against breast cancer
« on: July 10, 2013, 11:13:33 AM »
The study was a component of a larger international trial, for which similar results were announced last year.

"I think it's huge because it's the second trial to show a benefit for 10 years versus five years," said Dr. Sandra Swain, medical director of the Cancer Institute at Washington Hospital Center and president of the American Society of Clinical Oncology, or ASCO. "It is important not only in the US, but for the world. It is a very inexpensive drug."

Tamoxifen, available as a low-cost generic, has long been used for younger, premenopausal, women with early-stage breast cancer that responds to estrogen. Most start taking the estrogen-blocking drug immediately after completing their initial surgery or chemotherapy.

Around 70 percent of breast cancers are estrogen-receptor positive, meaning they are fueled by the hormone.

ASCO guidelines now call for women at increased risk of breast cancer to take tamoxifen for five years. For postmenopausal women, the guidelines say raloxifene, an estrogen receptor modulator sold by Eli Lilly under the brand name Evista, may also be considered.

The latest findings, presented at the annual ASCO meeting in Chicago this weekend, found that side effects increased with longer tamoxifen use, but concluded that overall benefits outweigh those risks.

Researchers estimated that, compared with taking no tamoxifen, 10 years of the drug reduces breast cancer death rates by a third in the first 10 years and by half after that.

"Until now, there have been doubts whether continuing tamoxifen beyond five years is worthwhile," said lead study author Richard Gray, professor of medical statistics at the University of Oxford.

Between 1991 and 2005, 6,953 women in the United Kingdom who had been taking tamoxifen for five years were randomly assigned to continue treatment or to stop immediately.

Breast cancer recurred in 16.7 percent of the 10-year group, compared with 19.3 percent in the five-year group.

Longer treatment also reduced the risk of dying from breast cancer. The women who continued tamoxifen treatment had a 25 percent lower recurrence rate and a 23 percent lower breast cancer mortality rate than the women who had been allocated to stop after only five years.

The results were called "practice changing for premenopausal women with hormone receptor-positive breast cancer," by Dr. Sylvia Adams, associate professor New York University School of Medicine.

In the United States, postmenopausal women at high risk of breast cancer are usually offered drugs in a newer class known as aromatase inhibitors, such as Arimidex, sold by AstraZeneca.

"For pre-menopausal women the standard of care will likely include 10 years of tamoxifen," Dr. Adams said. "For women who enter menopause during that period, AIs are still an option. Tamoxifen will also be an option."

Rare but serious side effects of tamoxifen include increased risk of endometrial cancer (cancer of the lining of the uterus), blood clots and stroke.

The British researchers said they observed no excess incidence of stroke with 10 years of tamoxifen therapy, although the endometrial cancer risk was higher. They estimated that for every endometrial cancer death that occurs as a side effect of long-term tamoxifen, 30 deaths from breast cancer would be prevented.

Health Tips / Urine odour test for bladder cancer
« on: July 10, 2013, 11:10:47 AM »
It uses a sensor to detect gaseous chemicals that are given off if cancer cells are present.

Early trials show the tests gives accurate results more than nine times in 10, its inventors told PLoS One journal.

But experts say more studies are needed to perfect the test before it can become widely available.

Each year around 10,000 people in the UK are diagnosed with bladder cancer.
Doctors have been searching for ways to spot this cancer at an earlier stage when it is more treatable.

And many have been interested in odors in urine, since past work suggests dogs can be trained to recognize the scent of cancer.

Prof Chris Probert, from Liverpool University, and Prof Norman Ratcliffe, of the University of the West of England, say their new device can read cancer smells.

"It reads the gases that chemicals in the urine can give off when the sample is heated," said Prof Ratcliffe.

To test their device, they used 98 samples of urine - 24 from men known to have bladder cancer and 74 from men with bladder-related problems but no cancer.

Prof Probert said the results were very encouraging but added: "We now need to look at larger samples of patients to test the device further before it can be used in hospitals."

Dr Sarah Hazell, senior science communication officer at Cancer Research UK, said: "It would be great to be able to detect the 'smell' of cancer in a robust and practical way but, promising though this work is, we're not there yet.

"This latest method is still at an early stage of development, and needs to be tried out on a much larger set of samples, including samples from both women and men.

"The researchers say that the test would be around 96% accurate in practice and their findings are only based on a relatively small number of samples, taken only from men. But it is another promising step towards detecting bladder cancer from urine samples, something that would ultimately provide a less invasive means of diagnosing the disease."

Health Tips / Muscle power truths' revealed
« on: July 10, 2013, 11:08:46 AM »
Bulging biceps get their power from a mesh arrangement of cells rather than long ropes, detailed studies reveal.

As muscles flex, tugging filaments fan out in a lattice, say the University of Washington team who made the breakthrough.

This generates force in multiple directions, not just up and down the muscle, Proceedings B journal reports.

And it's not just biceps that use this force - all muscles, including the heart appear to do it.

Prof Thomas Daniel, one of the researchers, said: "This aspect of muscle force generation has flown under the radar for decades and is now becoming a critical feature of our understanding of normal and pathological aspects of muscle."

The basics of how muscle generates power remain the same - filaments of myosin tug on filaments of actin to shorten or contract the muscle.

But myosin doesn't tug in one direction, as previously thought. Instead, it pulls at angles and this gives radial force.

The news will be of interest to bodybuilders who strive to max their muscle power, but could also help doctors treating heart problems.

Co-author Michael Regnier said: "In the heart especially, because the muscle surrounds the chambers that fill with blood, being able to account for forces that are generated in several directions during muscle contraction allows for much more accurate and realistic study of how pressure is generated to eject blood from the heart.

"The radial and long axis forces that are generated may be differentially compromised in cardiac diseases and these new, detailed models allow this to be studied at a molecular level for the first time."

Health Tips / Air pollution 'harmful for those with failing hearts
« on: July 10, 2013, 11:05:57 AM »
The British Heart Foundation, which funded The Lancet work, says the UK must clean up its air - many of its cities often exceed safe levels set by the European Union.

The government has already admitted that in 15 regions, air quality will breach EU limits until 2020.

But Defra says it is committed to improving air quality and that most parts of the UK meet EU air quality limits for all pollutants.

Air pollution, largely from traffic fumes, has previously been linked to heart attacks but not heart failure.

This happens when the heart muscle becomes weak and less good at its job of pumping blood around the body. It is often the consequence of a heart attack and affects more than 750,000 people in the UK.
Deep into lungs

The Lancet research looked at 35 studies with data for thousands of patients in 12 countries, including the UK, the US and China.

The strongest link was found with gases such as carbon monoxide and nitrogen dioxide, as well as fine particulate air pollution - fumes from buses, taxis and lorries that can get deep into the lungs and, from there, into the bloodstream.

People with already weakened hearts who were exposed to high levels, by living near to or travelling along busy roads, for example, were particularly susceptible.

And the increased risk seems to be strongest on the day of exposure.

Dr Anoop Shah and colleagues who carried out the work say moderate reductions in air pollution could avoid 8,000 US hospital admissions for heart failure each year.

"There's no reason why the impact wouldn't be similar in the UK."

Alan Andrews of the lobby group Client Earth said: "The UK has a big problem with air pollution, particularly from road traffic, and the government response sadly has been worse than useless."

He said people should be alerted when pollution levels are high so that they can take measures to protect themselves, by staying indoors when possible and avoiding busy roads.

According to the World Health Organization, air pollution in towns and cities kills 1.3 million people globally each year.

UK estimates suggest nearly 30,000 people die prematurely each year as a direct result of exposure to air pollution. Air pollution has been linked to asthma and other lung diseases, including cancer, as well as heart problems.

The Chief Medical Officer recently highlighted the impact of air pollution in her first annual report on the state of the nation's health - air pollution was highlighted among the top 10 causes of mortality in the UK.
