Smoking
weakens anti-clotting effect of aspirin
NEW YORK, Oct 3: By increasing the activity
of platelets, blood cells that help clot the
blood, smoking may weaken the anti-clotting
effect of aspirin, new research suggests.
A
small daily dose of aspirin is usually
recommended for patients who have had a heart
attack or stroke to prevent platelets from
building up and blocking critical blood vessels.
''Aspirin
and other antiplatelet treatments are central to
the prevention of heart attack and stroke,'' Dr.
Michael Domanski told Reuters Health. ''A clearer
understanding of how to best predict the level of
protection provided in a specific individual is a
research question of potentially great public
health importance.''
As
they report in the American Journal of
Cardiology, Domanski of the National Heart, Lung
and Blood Institute in Bethesda, Maryland and
colleagues conducted a study to determine which
factors predict a poor anti-clotting response to
aspirin.
About
one third of the 123 patients in the study were
smokers. Their ages ranged from 21 to 95 years.
About half of the subjects were women and most
had high blood pressure, as well as heart
disease.
Sixty-six
patients were taking low-dose aspirin at 81
milligrams per day, and tests showed that eight
of them did not respond to the drug. When the
dose was increased to 325 mg per day, only one
remained resistant.
In
the other 57 patients, who were taking 325 mg of
aspirin per day, three were resistant. When they
were given a dose of clopidogrel (Plavix),
another anti-platelet drug, and tested 4 hours
later, two had become responders.
In
the final analysis, smokers were nearly 12-times
more likely to be resistant to aspirin than were
non-smokers. Thus, the researchers conclude, the
finding ''adds still more weight to the
importance of abstinence from smoking.''

India attacks
Security Council for failing to meet obligations
UNITED
NATIONS, Oct 3: India has lambasted the 15-member
Security Council for failing to meet its
obligations of maintaining international peace
and security, saying it is the result of its
"un-representative" character and
consequent lack of political will.
In a sharp
criticism of the Councils inaction as the
"tragic events" unfolded in Lebanon
recently and the Mideast peace process was
derailed, Indian Ambassador Nirupam Sen likened
the Council to Emperor Nero who was fiddling
while Rome was burning.
"The main
problem that beset peacekeeping are not lack of
resources or even personnel, but an
un-representative Security Council which lacks
the political will to act and when it does, does
so in a manner that is entirely inadequate,"
he told the United Nations General Assembly.
Asking the Council
members to shore up their participation in the
peacekeeping operations, Sen said it is a
"distressing reflection" on their
willingness to share the burden of maintaining
international peace and security when
overwhelming number of troops in the peacekeeping
operations are contributed by the developing
nations.
Stressing that
reform of the United Nations, which the major
power are demanding, would be incomplete without
the expansion of the 15-member Council, he said
it needs to be made more representative and
effective if it is to satisfactorily perform the
role mandated to it by the Charter.
It is imperative,
Sen said, that any expansion and restructuring of
the Council must include developing countries in
both permanent and non permanent categories.

In
locked-down Baghdad, city life moves
online
BAGHDAD, Oct 3: In the endless
daily battle against the fear and
isolation of life under lock-down, the
people of Baghdad have found a way to
keep their city alive: moving it online.
Instead of
enjoying an outdoor meal at one of the
fish restaurants along the Tigris
embankment, 28-year-old housewife Dunya
Saad spends her evenings at the computer
in her living room, chatting with her
friends on Yahoo! Messenger.
Most of
her relatives and friends live on the far
side of the Tigris, and seeing them in
person is nearly impossible.
''It's sad
not to see your friends like in the good
old days,'' she sighed. ''But online
chatting has made things better.''
Since the
February bombing of a Shi'ite shrine in
Samarra sparked a wave of sectarian
bloodshed, the Internet has gone from
being a hobby for tech-savvy enthusiasts
to a mass replacement for the daily
interactions of city life.
In
Baghdad, shops close early. Cars are not
permitted on the streets after 9:00 p.M.
Many parts of the city are completely
deserted by sunset.
Hundreds
of thousands of people have been forced
to move to parts of the city where they
do not know the neighbours.
''I only
go out on emergencies like attending a
funeral or visiting a doctor,'' said
Zainab, 35, an office secretary who asked
to be identified by her first name.
''Honestly, the outside craziness freaks
me out.''
She has
not seen her friends for months. Instead,
she meets them over online
video-conferences.
''Most of
the time we talk about the security
situation. Who had been killed,
kidnapped, or recently fled the
country.''
BUSINESS
OPPORTUNITY
Moving
Baghdad into cyberspace has been a feat
of free- market ingenuity.
Perhaps
the hardest part is electricity. Much of
Baghdad had electricity for 12-18 hours a
day before the U.S.-led invasion in 2003.
Most neighbourhoods now get electricity
from the grid for just four to six hours
a day.
It means
ordinary people have to know their ohms
from their amperes and their megabits
from their kilohertz.
Most
middle class households now have cables
snaking down the street to a
neighbourhood ''generator man'' who gives
them diesel-generated power for a monthly
fee of about 10 dollars per ampere. Six
or seven amperes are usually enough for a
computer, a TV and a fridge. An air
conditioner costs more.
A
neighbourhood Internet cafe will sell a
subscription for wireless Wi-Fi access to
its satellite broadband hookup for about
40 dollars a month.
Most
Iraqis have only experienced the Internet
since the fall of Saddam Hussein in 2003.
The ousted
leader officially linked Iraq to the Web
when his government set up the State
Company for Internet Services in 2000.
But private connections were banned and
the only legal provider blocked access to
e-mail and chat sites.
Companies
have today sprung up around Baghdad,
taking advantage of new broadband
satellite connections that make it
possible to establish a mini internet
service provider without relying on any
centralised infrastructure at all.
Ali
Youssif, whose company Infozone runs four
Internet providers in different parts of
Baghdad, says he subscribes to satellite
broadband connections from firms in
Kuwait and the United Arab Emirates.
One of his
providers has a two-megabit-per-second
connection -- a similar speed to a single
home's broadband link in most Western
countries -- which costs about 7,000
dollars a month over satellite.
It sells
access to 200 subscribers across three
Baghdad neighbourhoods, earning a total
of about 8,000 dollars in revenue.
Private
generators power the Wi-Fi hotspots
during the day, with batteries offering
up to 200 amperes of power to keep them
running without interruption through the
night.
LOVE
ONLINE
For
freelance journalist Ammar Ali, 30, the
Internet is a place to find love in a
city where flirting with a woman can get
a man kidnapped or killed.
He has
only been online for about a year, but he
already has a long list of ''female
friends'' with whom he keeps in touch on
a nearly daily basis. Some live in other
neighbourhoods, some in other countries.
''It's not
like reality. But I enjoy it,'' he says.
''It's a good means to escape our
miserable reality. At least, until a new
morning comes.''(AGENCIES)

China
set to curtail TV serials showing
extramarital affairs
BEIJING,
Oct 3: China, witnessing soaring
divorces, may restrict the number of soap
operas and TV dramas depicting
extramarital affairs, the state media
reported today.
The State
Administration of Radio, Film and
Television, is planning restrictions,
although no timetable has been set,
Beijing-based Legal Evening
News reported.
Television
series featuring crime and soap operas
showing ancient China or marriage and
family life used to be the focus of TV
popular culture.
However,
as it was believed that soap operas about
crime could have a negative impact on
young people, the government decided in
2004 to withdraw such TV series from
prime time slots on major stations.
More soap
operas focused on extramarital affairs
because the producers thought they would
have a larger audience than before,
China Daily reported.
But some
scholars hit back, saying the market
should decide what is suitable content
for a TV series, not the government.
An arts
professor at Peking University, Zhang
Yiwu said that although soap operas on
marriage issues have many shortcomings,
the government should deal with the issue
prudently.
"Many
people love to watch such television
series. Such operas also give warnings
not to break the law," he said.
Quoting
the findings of an online survey, the
paper said that over half the people
questioned said soap operas showing
extramarital affairs would have a
negative impact on the stability of
marriage and affect the development of
young people. (PTI)

Indonesian
Muslims axe 100-year-old tree
JAKARTA, Oct 3: Muslim hard-liners
chopped up a 100-year-old banyan tree in
Jakarta to halt a rumour about its
special powers from spreading among
superstitious locals, prompting city
authorities to report the attackers to
police, officials said today.
Islam is a
strongly monotheistic religion, and
believing in any power other than God is
considered a grave sin. Hard-liners in
Indonesia often criticise other Muslims
for still practicing Hindu, Buddhist and
animist rituals that predate Islam's
arrival in the archipelago.
The
sprawling tree's branches were hacked
away Sunday, leaving just its trunk, said
Sarwo Handayani, head of the city's park
agency.
Earlier,
rumours had spread that cutting down the
tree would bring bad luck because it was
spared during a tree-felling drive to
make way for a new bus lane in central
Jakarta, Handayani said.
He said
the rumours gained strength after
unidentified people left offerings at the
tree's base.
Handayani
dismissed the rumours of supernatural
involvement as nonsense, saying officials
did not fell the tree because the bus
lane could be routed around it.
"This
was an outrageous act," he said of
the damage to the tree, adding that he
had reported it to police on Sunday as an
act of vandalism. (AP)

Japan
PM to visit China, Korea on Oct 8,9-NHK
TOKYO, Oct 3: Japanese Prime
Minister Shinzo Abe, who took office last
week, will visit China on October 8 and
South Korea on October 9 for
fence-mending summits, public broadcaster
NHK said on Tuesday.
Leaders of
the two countries, where bitter memories
of Japan's wartime aggression run deep,
had refused to meet Abe's predecessor,
Junichiro Koizumi, because of his visits
to a Tokyo war shrine seen by many as a
symbol of Japan's militaristic past.
A Foreign
Ministry spokesman said he could not
confirm the dates reported, while
Japanese media said the government was
likely to make an official announcement
tomorrow.
Deputy
Chief Cabinet Secretary Hakubun Shimomura
told a news conference that negotiations
were being made with both nations for
summits.
''On the
question of the Japan-China summit, both
sides are making efforts to bring it
about quickly. Japan always has its door
open,'' he said, adding that dates were
being negotiated for a Japan-South Korea
summit.
A
spokeswoman for the Chinese Foreign
Ministry, when asked about the NHK
report, said: ''We don't have information
about that.''
Abe, who
took over as prime minister last week,
has supported Koizumi's visits to
Yasukuni Shrine but has declined to say
if he would pay his respects there while
in office. An adviser to Abe has said he
went to Yasukuni last April, when he was
a cabinet minister, but Abe has neither
confirmed nor denied that.
''I'd like
to continue to pray for those who
sacrificed their lives for the nation and
to have a feeling of reverence for
them,'' Abe reiterated to parliament
today.
Government
officials have said Japan and its Asian
neighbours were trying to find a way out
of the diplomatic deadlock due largely to
differing views of their wartime past,
which has chilled relations and
threatened to disrupt vital economic
ties.
Abe also
referred again to a historic 1995
Japanese government statement in which
then-Prime Minister Tomiichi Murayama
apologised for suffering Japan caused in
Asia with its military aggression in the
1930s and 1940s.
China and
Japan have not held a summit since April
last year, and the South Korean and
Japanese leaders have not met formally
since last November.(AGENCIES)

Spain
official rapped for parliament video
stunt
MADRID, Oct 3: A Spanish official
has been disciplined for allowing four
pranksters to sneak into parliament and
video themselves pretending to steal the

about a spoof video posted on the
Internet, which showed four hooded
figures stealing the chair Prime Minister
Jose Luis Zapatero sits on during
debates, it said in a news release
yesterday.
''The

the parliament said, adding that it had
disciplined one of its own officials for
letting in the pranksters, who had been
identified..
A group
calling itself Four Cats posted the video
on the Internet at

Well-preserved
ancient kilns unearthed in
southwest China
BEIJING, Oct
3: Chinese
archaeologists have unearthed a
well-preserved cluster of rare
kilns dating back to the Eastern
Han Dynasty (25 AD to 220 AD) in
southwest China's Guizhou
Province, a report said today.
The six kilns cover
an area of about 500 square
metres on a hillside plateau near
the Wujiang River in Hongdu Town.
Plate and arched
tiles, oblong bricks and pieces
of pottery were unearthed at the
site. The style of the bricks
indicated the site was built
during the Eastern Han Dynasty,
an associate research fellow with
the Guizhou Cultural Relics and
Archaeology Institute, Zhang
Herong said.
Adjacent to the
kilns were a number of tombs made
of similar bricks, indicating the
kilns mainly made bricks and
pottery figurines for tombs.
The find would help
in the study of the production
procedures of kilns in the
Eastern Han Dynasty and contacts
between Wujiang River communities
by analysing the distribution of
the bricks. (PTI)

Asians
seek to break western literary
stranglehold
UBUD, INDONESIA, Oct
3: Indonesian author Vira
Safitri is only 18, but already has two
novels under her belt.
In a world
where awareness of eastern culture often
stops at Jackie Chan and Zhang Ziyi, a
new breed of Asian writer is aiming to
turn pages with writing inspired by
distinctly Asian issues: such as the
repression of women, the politics of the
hijab, political dissidence and eastern
mythology.
Asked how
long it took to write her first novel,
''Secret Admirer'', a giggling Safitri
said: ''Four days and three nights.''
''And in
another week's time I had a publisher,''
she added.
Her two
books, which touch on issues such as
romance and child abuse from a teenage
perspective, have jointly sold 9,000
copies and she is hoping they will be
translated from her native Indonesian to
English to get wider coverage.
Safitri is
one a growing breed of Asian authors
writing in a uniquely eastern idiom who
were at a writers' festival in the
Balinese resort town of Ubud seeking to
make themselves heard above the western
literary clamour.
''Around
two-third of the world's population lives
in Asia while 90 per cent of the world's
culture is western. That's a huge anomaly
and anomalies have a habit of correcting
themselves,'' Hong Kong-based writer Nury
Vittachi told Reuters.
''It's
already happening. There are literary
festivals in Hong Hong, Ubud and
Shanghai. Publishers are coming here. At
one time there were no literary agents
here, but now it's opening up,'' said the
shaven-headed author who has written more
than 20 books, including a successful
series about a Feng Shui detective, C.F
Wong.
With
literary agents and publishers heading
there, not surprisingly the Asian
equivalent of the Booker prize is going
to be launched this year.(AGENCIES)

Older
insomniacs helped by brief behavior
therapy
NEW YORK, Oct 3: Older adults who
suffer from insomnia may find it easier
to drift off to sleep following brief
behavioral therapy in which they learn
about mechanisms that regulate sleep,
factors that influence sleep, and
behaviors that promote or interfere with
sleep.
Sleep
specialists from Pennsylvania found that
12 of 17 elderly insomniacs (17 per cent)
who participated in a single behavioral
therapy session and a booster session
slept better and had less anxiety and
depression. Nine participants (53 per
cent) met criteria for remission of
insomnia following treatment.
By
contrast, only 7 of 18 insomniacs (39
percent) assigned to an
''information-only'' control group saw
improvements in sleep and reductions in
anxiety and depression and just three (17
per cent) met criteria for remission of
their insomnia.
Insomnia
is a ''chronic and prevalent'' problem in
adults older than 65 years, note Dr.
Daniel J. Buysse and colleagues from the
University of Pittsburgh School of
Medicine in the Journal of Clinical Sleep
Medicine. Hypnotics can help but these
medications ''raise safety concerns'' in
older adults and standard behavioral
therapy is time consuming, with standard
programs given over 6 to 8 weeks.
The brief
behavioral therapy intervention (BBTI)
the Pittsburgh team developed comprises a
single, 45-minute educational session
with a follow up 30-minute booster
session two weeks later.
During the
sessions, a trained nurse provides
individually tailored advice on getting
to sleep and staying asleep. For example,
subjects are encouraged not to do to bed
until sleepy and not to stay in bed
unless asleep and to get up at the same
time each day.
''We
tried,'' Buysse said, ''to identify the
active elements from treatments that have
been previously described and kind of
boil them down into just the basics so
that we could present a treatment to
people quickly, give them specific
recommendations on how they might change
their behavior to improve their sleep and
it seems to be promising.''
According
to the researchers, the ''BBTI group
showed large improvements in overall
sleep quality, sleep latency, wake time
after sleep onset, and sleep efficiency
as well as marked reductions in
depression and small changes in anxiety,
whereas the information-only control
group did not.''
The
magnitude of the sleep improvements with
BBTI were comparable with those reported
for traditional longer behavioral and
cognitive-behavioral interventions for
insomnia, they also note. (AGENCIES)

Cured
lepers still live in "colonies"
in China
PANYU, CHINA, Oct 3:
The old men hunched over a
board game looked like any other
pensioners playing chess, until they
lifted their heads to welcome medical
staff approaching their table.
Scarred by
leprosy, some of the men have collapsed
noses and others have missing fingers,
easily visible as they held up their
hands to greet their doctors.
All of the
inhabitants at the Panyu leprosy village
in southern China have recovered from the
potentially debilitating skin disease and
are no longer infectious.
But many
are badly disfigured and blind and are
utterly incapable of rebuilding their
lives after being forcibly
institutionalised for decades, far away
from their families.
Panyu is
one of hundreds of ''leprosy villages''
in China, a legacy from the 1950s when
very little was known about leprosy, or
Hansen's disease.
Mistaken
as a very infectious or even incurable
disease, those diagnosed with leprosy
were exiled to remote villages and
forgotten.
Ou Feng
was diagnosed with leprosy at the age of
18 and sent to live on Panyu, a tiny
island in southern Guangdong province.
Now 78,
she is excited to greet visitors,
grasping their extended hands and holding
them for a long time.
''We have
lunch ready for you. Please eat now, we
are so happy when you come,'' said Ou.
Until
recently leprosy sufferers were shunned
due to an incorrect belief their illness
was highly infectious. Lepers were turned
into outcasts and often sequestered in
''leper colonies''. (AGENCIES)

Viagra
may aggravate severe apnea
NEW YORK,
Oct 3: Viagra (sildenafil) taken at
bedtime may worsen breathing problems in
patients with severe obstructive sleep
apnea, results of a study published in
the Archives of Internal Medicine
suggest.
Obstructive
sleep apnea is a common problem that
occurs when the soft tissues at the back
of the throat collapse and close off the
airway during sleep, resulting in brief
moments in which breathing stops.
Impotence,
also known as erectile dysfunction, is
highly prevalent in patients with
obstructive sleep apnea, note Dr. Suely
Roizenblatt, of Federal University of Sao
Paulo, Brazil, and colleagues. However,
sildenafil prolongs the action of nitric
oxide, which promotes upper airway
congestion.
The
researchers therefore examined the
effects of a single 50-mg dose of
sildenafil on the sleep of 14 men
(average age, 53.1 years) with severe
obstructive sleep apnea.
The
subjects were randomly assigned to
receive sildenafil or a placebo (''sugar
pill'') before they participated in an
all-night sleep study, which included at
least 7 hours of recording time). The
subjects switched treatments and process
was repeated the next night.
Compared
with placebo, sildenafil led to a
significantly increased desaturation
index, the number of episodes of oxygen
reduction per hour of recording time
(30.3 events per hour versus 18.5 events
per hour). There was also a significant
increase in the percentage of total sleep
time with an oxygen saturation of less
than 90 per cent (15.6 per cent versus
7.9 per cent) and a significant increase
in the maximal duration of a desaturation
event (72.5 s versus 48.1 seconds).
Sleep
structure was also altered by sildenafil
use, with in increase in stage 2
non-rapid eye movement sleep compared
with placebo and a decrease in deep sleep
compared with the start of the study and
placebo, Dr. Roizenblatt's team reports.
Because of
the small sample size, the results should
not be extrapolated to all obstructive
sleep apnea patients. ''Nevertheless,''
they say, ''sildenafil should be used
with caution for treating erectile
dysfunction in individuals with a
sleep-related breathing
disorder.''(AGENCIES)
