People who look young for their age ‘live longer’

Filed under: Health — @ 12:31 am

People blessed with youthful faces are more likely to live to a ripe old age than those who look more than their years, work shows.

Danish scientists say appearance alone can predict survival, after they studied 387 pairs of twins.

The researchers asked nurses, trainee teachers and peers to guess the age of the twins from mug shots.

Those rated younger-looking tended to outlive their older-looking sibling, the British Medical Journal reports.

Survival advantage

The researchers also found a plausible biological explanation for their results.

Key pieces of DNA called telomeres, which indicate the ability of cells to replicate, are also linked to how young a person looks.


Perceived age, which is widely used by clinicians as a general indication of a patient’s health, is a robust biomarker of ageing that predicts survival among those aged over 70

The report authors

A telomere of shorter length is thought to signify faster ageing and has been linked with a number of diseases.

In the study, the people who looked younger had longer telomeres.

All of the twins were in their 70s, 80s or 90s when they were photographed.

Over a seven-year follow-up the researchers, led by Professor Kaare Christensen of the University of Southern Denmark, found that the bigger the difference in perceived age within a pair, the more likely it was that the older-looking twin died first.

Pavos Nocturnus

Filed under: Health — @ 7:02 pm

A night terror, also known as a sleep terror or pavor nocturnus, is a parasomnia disorder characterized by extreme terror and a temporary inability to regain full consciousness. The subject wakes abruptly from slow-wave sleep,
with waking usually accompanied by gasping, moaning, or screaming. It
is often impossible to awaken the person fully, and after the episode
the subject normally settles back to sleep without waking. A night
terror can rarely be recalled by the subject. They typically occur
during non-rapid eye movement sleep

The lack of a dream itself leaves those awakened from a night
terror in a state of disorientation much more severe than that caused
by a normal nightmare. This can include a short period of amnesia
during which the subjects may be unable to recall their names,
locations, ages, or any other identifying features of themselves.

In children

Children from age two to six are most prone to night terrors, and they affect about fifteen percent of all children,[1] although people of any age may experience them. Episodes may recur for a couple of weeks then suddenly disappear.[citation needed] The symptoms also tend to be different, like the child being able to recall the experience, and while nearly arisen, hallucinate.[citation needed] Strong evidence has shown that a predisposition to night terrors and other parasomniac disorders can be passed genetically.[citation needed]
Though there are a multitude of triggers, emotional stress during the
previous day and a high fever are thought to precipitate most episodes.[citation needed]
Ensuring the right amount of sleep is an important factor. Night
terrors may also be caused by stress and constipation and other
irregular bowel movements or lack thereof.[citation needed] Special consideration must be used when the subject suffers from narcolepsy, as there may be a link.[citation needed]

Common elements

A typical night terror episode usually occurs in the first hour of sleep. The child sits up in bed and screams, appearing awake but is confused, disoriented, and unresponsive to stimuli. Although the child seems to be awake, the child does not seem to be aware of the parents’ presence and usually does not talk. The child may thrash around in bed and does not respond to comforting by the parents. The child’s heart rate can escalate during the terror, along with sweating and harsh breathing. [1]

Most episodes last only a few minutes, but they may last up to 3 hours before the child relaxes and returns to normal sleep.

In some cases the night terror could be recalled by the person, depending on age and the nature of the episode.

Treatment

Since night terrors are most commonly triggered by being overtired, sometimes no treatment is necessary except for a bedtime schedule that ensures proper sleep. If the night terrors are more frequent, however, it has been suggested that the sufferer should be awakened from sleep just before the time when the terrors occur most to interrupt the sleep cycle.

When a drug patent<br />expires, makers of generics often rush to the forefront and capture<br />business from the original drugmaker.  However, this has not happened<br />yet due to an interesting court case begun by Cephalon.  Four<br />companies applied to the US FDA for approval to market generic<br />versions of Provigil and they were all granted approval to make the<br />generics.  Cephalon filed suit against all these companies for patent<br />infringement and the companies all settled out of court, in what some<br />have seen as a form of blackmail.<br /><br />United Senior Action<br />"Help Challenge Drug Industry Attempts to Keep Generics off the Market"<br /><a href="http://www.usaindiana.org/challenge.cfm">http://www.usaindiana.org/challenge.cfm</a><br /><br />"The case, which was filed in June 2006, claims that Cephalon, the<br />brand name manufacturer of Provigil, conspired with generic drugmakers<br />Teva, Ranbaxy, Barr and Mylan to keep generic versions of Provigil off<br />the market. The case alleges that when Cephalon's exclusive marketing<br />rights were set to expire, the generic companies applied for FDA<br />approval to market generic versions of the drug. Although the FDA<br />determined that each company had developed safe, effective and<br />bioequivalent generic versions of Provigil, they could not begin<br />marketing the drugs because Cephalon filed patent infringement<br />lawsuits against them.<br /><br />Although they had strong arguments for invalidating Cephalon's patent<br />for Provigil, all four generic companies settled their cases with<br />Cephalon. Under these settlement agreements, each generic company<br />agreed to keep their generic versions of Provigil off the market until<br />2011 or 2012, in exchange for cash payments. The three payments to<br />Teva, Ranbaxy and Barr alone totaled up to $136 million."<br /><br />Apotex, another generic drugmaker, has sued all the parties involved<br />alleging monopolistic practices.<br /><br />"Apotex Accuses Cephalon and Four Generic Drug Companies of<br />Monopolizing the U.S. Market for Provigil"<br /><a href="http://www.orangebookblog.com/2006/07/apotex_accuses_.html">http://www.orangebookblog.com/2006/07/apotex_accuses_.html</a><br /><br />-----------<br /><br />Provigil's sales (Cephalon)<br />2005-- $500 million<br />2004-- $289 million<br />2003-- $200 million<br />2002-- $150 million<br />2001-- $75 million<br /><br />More than a million people have been prescribed Provigil in the United<br />States; since it is primarily approved for narcolepsy and there are<br />only 150,000-200,000 narcoleptics in the US, people are not just<br />taking it for narcolepsy but to remedy other sleep disorders.

How do they buy it? <br /><br />Most people who take modafinil have a prescription.  Ninety percent of<br />the prescriptions are for off-label usage-- to combat sleep<br />deprivation and other ailments.  With a prescription, modafinil can be<br />readily obtained from any pharmacy or chemists'.   Like any<br />prescription drug, it can also be bought at online pharmacies, which<br />may or may not have more competitive prices.  Provigil is expensive.<br /><br />If you are in the United States, Provigil is a Schedule IV controlled<br />substance, which means it's illegal to import it from a foreign<br />source.  In other countries, it is not considered a controlled<br />substance and is not illegal to buy from other sources.<br /><br />One thing a buyer of modafinil will find is that Provigil is more<br />expensive than Alertec or Modalert, the foreign forms of the drug.<br />This is because, while the different formulations are chemically the<br />same, Canadian and Indian manufacturers of the drug use different pill<br />shapes and formulas that are not covered under Cephalon's US patent.<br />Because they are "generics," although not official generics, Alertec<br />and Modalert are generally less expensive than Provigil.<br /><br />Here are some places from which people have bought Provigil<br />successfully (with the recommendations I found):<br /><br />Good Health Pharmacy<br /><a href="http://www.goodhealthpharmacy.com/new/catalog/product_info.php?ref=1&products_id=618&affiliate_banner_id=1">http://www.goodhealthpharmacy.com/new/catalog/product_info.php?ref=1&products_id=618&affiliate_banner_id=1</a><br /><br />from:<br />"Modalert/Provigil CHEAP!"<br />topix.net<br /><a href="http://www.topix.net/forum/health/narcolepsy/T5G91I20L8QQNE68F">http://www.topix.net/forum/health/narcolepsy/T5G91I20L8QQNE68F</a><br /><br />Quality Health-- UK<br /><a href="http://www.qhi.co.uk/list.asp">http://www.qhi.co.uk/list.asp</a><br /><br />Biogenesis--<br />sells three different forms of modafinil<br /><a href="http://www.biogenesis-antiaging.com/advanced_search_result.php?search_in_description=1&keywords=modafinil&osCsid=6e324d4476e5bdd256f25eee7f9f3492&x=0&y=0">http://www.biogenesis-antiaging.com/advanced_search_result.php?search_in_description=1&keywords=modafinil&osCsid=6e324d4476e5bdd256f25eee7f9f3492&x=0&y=0</a><br /><br />Modalert at Jan Drugs<br /><a href="http://www.jandrugs.com/momex/NavCode/drugs/DrugName/Provigil">http://www.jandrugs.com/momex/NavCode/drugs/DrugName/Provigil</a><br /><br />Other recommendations from the Imminst.org thread are:<br />Freedom Pharmacy (Modalert)<br /><a href="http://freedom-pharmacy.com/Products2.asp?Brand=MODALERT+%28Modafinil%2CProvigil%29&T=m">http://freedom-pharmacy.com/Products2.asp?Brand=MODALERT+%28Modafinil%2CProvigil%29&T=m</a><br /><br />Pharma-Orders<br /><a href="http://www.pharma-orders.com/advanced_search_result.php?osCsid=8612ccc28983aaef6d530636d20a1cb6&keywords=modafinil&osCsid=8612ccc28983aaef6d530636d20a1cb6&x=0&y=0">http://www.pharma-orders.com/advanced_search_result.php?osCsid=8612ccc28983aaef6d530636d20a1cb6&keywords=modafinil&osCsid=8612ccc28983aaef6d530636d20a1cb6&x=0&y=0</a><br /><br />Sun Pharma-- Modalert<br /><a href="http://www.sunpharma.com/sunpharma-products/sunpharma-formulation/spopup13.php">http://www.sunpharma.com/sunpharma-products/sunpharma-formulation/spopup13.php</a><br />
