Yeon-Kyun Shin, a biophysics
professor in the department of biochemistry, biophysics and molecular biology,
says the results of his study show that drugs that inhibit the liver from
making cholesterol may also keep the brain from making cholesterol, which is
vital to efficient brain function.
"If you deprive cholesterol
from the brain, then you directly affect the machinery that triggers the
release of neurotransmitters," said Shin. "Neurotransmitters affect
the data-processing and memory functions. In other words -- how smart you are
and how well you remember things."
Shin's findings will be
published in this month's edition of the journal Proceedings of the National Academy of Sciences.
Cholesterol is one of the
building blocks of cells and is made in the liver. Low-density lipoprotein (LDL)
-- often referred to as bad cholesterol -- is cholesterol in the bloodstream
from the liver on the way to cells in the body.
High-density lipoprotein (HDL) -- so-called good cholesterol -- is cholesterol
being removed from cells. Too much LDL going to cells and not enough being removed can lead to cholesterol deposits and
hardening of the cells.
"If you have too much
cholesterol, your internal machinery is not going to be able to take away
enough cholesterol from the cells," said Shin. "Then cells harden and
you can get these deposits."
Cholesterol-reducing statin
drugs are helpful because they keep the liver from synthesizing cholesterol so
less of the substance is carried to the cells. This lowers LDL cholesterol.
It is the function of reducing
the synthesis of cholesterol that Shin's study shows may also harm brain
function.
"If you try to lower the
cholesterol by taking medicine that is attacking the machinery of cholesterol
synthesis in the liver, that medicine goes to the
brain too. And then it reduces the synthesis of cholesterol which is necessary
in the brain," said Shin.
In his experiments, Shin tested
the activity of the neurotransmitter-release machinery from brain cells without
cholesterol present and measured how well the machinery functioned. He then
included cholesterol in the system and again measured the protein function.
Cholesterol increased protein function by five times.
"Our study shows there is a
direct link between cholesterol and the neurotransmitter release," said
Shin. "And we know exactly the molecular mechanics of what happens in the
cells. Cholesterol changes the shape of the protein to stimulate thinking and
memory."
While reducing the cholesterol
in the brain may make you have less memory and cognitive skills, more
cholesterol in the blood does not make people smarter. Because cholesterol in
the blood cannot get across the blood brain barrier, there is no connection to
the amount of cholesterol a person eats and brain function.
Shin says that for many people
taking cholesterol-lower statins can be very healthful and they should listen
to their doctor when taking medication.
Getting
busted for doing over 100 mph is a lot like getting kicked out of camp for
being in a girl's bunk after dark. Sure, you're pissed you got caught, but it's
also going to make for a pretty good story.
While we would never advocate extreme speeding, with the right combination of
car and road, sometimes it's inevitable. Just make sure you don't let your
speedometer approach triple digits if you are in the state of
After the jump, check out our list of celebrity speeders who were clocked at
the century mark but avoided jail time.
10. Al Gore Jr. at 100 mph -- Little Albert did his poppa proud when
he proved to skeptics that the environmentally friendly Prius could really
move.
9. Nick Hogan at 100 mph -- The reality TV star's triple-digit
speeding stop came months before he was involved in a tragic accident at a
lower speed.
8. LeBron James at 101 mph -- The $80 million man brushed off
his $150 ticket as "no big deal."
7. Steve Wozniak at 104 mph -- The Apple
inventor and American citizen actually pleaded metric-system confusion. The
judge didn't buy it, and fined him $700.
6. Matt Dillon at 106 mph -- Kevin's older brother was clocked
on the open roads of
5. Tashera Simpson at 106 mph -- While we've pegged DMX as
a sure-fire celebrity speeder, it was his wife who was caught doing triple
digits in the family Mercedes. (With four unbuckled kids in the back.)
4. Chris Tucker at 109 mph -- The "Rush Hour"
star was pulled over for reaching 109 back in 2005, and we haven't really heard
from him since.
3. Ben Affleck at 114 mph -- Top that, Damon.
2. Eric Clapton at 134 mph -- Slowhand has a
lead foot. And his top speed got him banned from driving in
1. Koenigsegg CC at 242 mph -- Not technically a person, but
the Swedish supercar which was allegedly pulled over for doing 242 on a Texas
freeway during the Gumball 3000 rally race. If true, it would be the largest
speeding ticket ever issued.
Caught
at 100 MPH: Now What?
Basketball phenom LeBron
James has one. As does actor Matt Dillon. So, famously, does politician Al
Gore's son. You may think it's a Bentley,
Benz or even a Prius,
or the latest celebrity accoutrement, but we're not talking about that. All of
these famous individuals have a speeding
ticket citation for allegedly driving above 100 mph. As the three drivers
were cited in three different states, they all face varying combinations of
penalty fines, courts fees and possible license suspensions. But even if a
prospective fine won't hit LeBron's oversized pocketbook too hard, it often
adds up to a pretty penny for the average motorist once an insurance adjustment -- or
policy cancellation -- is taken into account. What does it mean to get caught
going triple digits? We take a look.
When You Hear About It
Maybe you were driving
too fast on a straight section of freeway and heard that ominous siren that
means a hefty speeding fine
is on the way. Maybe you were opening your mail over a cup of morning coffee
and noticed a letter with a funny-looking city insignia on it. Or maybe you
were sitting watching TV when you noticed a police car pulling up
outside then heard a knock on the door. However the police got to you -- and it
varies by the state you live in - you've now been cited for driving above 100
mph.
Likely Police Method
Vince Ramirez of the California
Highway Patrol says a 100 mph-plus driver may be caught either by radar or by
cruiser (known as a "bumper piece"). He says: "Upon a stop, the
officer will issue a citation and then it goes to county, where a court
determines the fine. He says most offenders are caught on "the outskirts
of big cities, high desert areas or rural populations."
Know Your Rights
When you've been pulled
over, most attorneys will advise you to not admit guilt, as it may complicate
challenging a ticket later. Likely a police officer will ask you how fast you
thought you were going, but you are under no obligation to answer. Be polite
and do not challenge the ticket right there, as it may annoy the officer,
undermining your case. Do not offer a bribe, a felony offense. There's nothing
to stop you asking for a warning only but, at 100 mph or more, it's not likely
you'll get it.
Varying Ticket Penalties
Penalties vary across
states and jurisdictions. In
Reckless Driving?
Whether an infraction
becomes a reckless driving offense depends on road conditions, how you were
driving, the officer serving your ticket and the state in which you received
it. Factors include if you were seen making unsafe lane changes or had a
passenger in your car (even more so if it's a child). Reckless driving is
usually a misdemeanor criminal offense. In
What about insurance?
Raleigh Floyd at Allstate
says a citation "typically won't affect the insurance situation unless it
involved a crash." In terms of a policy cancellation or increase, Floyd
says it's impossible to determine as "more than 1,000 factors that go into
it, including age, past driving record and where you drive." He says that
the offense will appear on DMV
records and will be noted for new customers or a policy renewal. His advice?
"Slow down for your own safety.
You'll also save on gas."
Do you need a lawyer?
David Haenel, at
Repeat offenders
Most states will escalate
punishment when a second offense has occurred within a given time period --
often five years. In most states, license suspension becomes mandatory and jail
time also lengthens. In the case of a third offense, jail time could be
mandatory. Officer Ramirez of the CHP confirms that these offenses are known as
"significant abuses" and could merit jail time. Advice? If possible
avoid getting one in first place. And if you get a second or third, look out!
10
Ways to Avoid a Cop Giving You a Speeding Ticket
People who get speeding
tickets are often guilty of more than simply driving faster than the posted
limit. Their chief offense? It's getting noticed in the first place. That's the
first domino to fall in the ugly chain of events that leads to a piece of
"payin' paper."
Here are some common
sense ways to run under a cop's radar -- literally:
· Drive within 5-10 mph
of surrounding traffic. Cops are usually looking
for drivers who are going noticeably faster than the other cars on the road. If
you're within a pack of cars all going 5 to 10 mph over the limit, you've
automatically improved your odds of not being the one that gets pulled over for
a speeding ticket, even though you're all technically speeding. The cop has to pick
one car; if you go with the flow of traffic, it probably won't be
you. And it definitely won't be you if you don't speed in the first place.
· Try to stay in the
middle of the pack. If you're the lead car, logic says
you'll be the first car to run past any cop's radar trap up ahead and get a
speeding ticket. And if you're the last car, you'll be the one the police
officer rolls up behind. That means the safest place is in the middle -- just
like a gazelle fleeing a hungry lion by seeking safety in the middle of the herd.
· Find a
"rabbit." If you can't find a pack of cars
going the speed you'd like to maintain, the next best thing is to find yourself
a rabbit -- a solitary driver traveling the speed you'd like to drive that you
can follow discretely, about 50-100 yards back. If there's a cop using radar,
hopefully the rabbit will trip the trap and get a speeding ticket, not you. And
if he brakes suddenly, you
have just received your early warning in time to take defensive action.
· Do not change lanes
frequently, tailgate or otherwise drive aggressively.
In addition to being rude and dangerous, you're just asking for a trucker or
someone with a cell phone to call the cops and give them a description of your
vehicle and license plate number. Always use your signals and be courteous to
fellow drivers. It's safer, and it will help you fade into the background.
· Avoid the fast lane. Use the far left lane to pass when necessary, but try to stay in the
middle lanes when possible. Reason? If a cop is lurking in a cutout along the
median strip (or coming at you from the opposite direction on a divided
highway) the speeder in the far left lane is the one most likely to become the
target. Drivers who get nailed with speeding tickets are often the type who
rack it up to 10 or 15 over the limit and remain in the far left lane.
· Watch for cutouts and
modulate your speed accordingly. On many highways, there
are cutouts in the median strip every couple of miles. Usually, you can see
these in plenty of time to slow down a little bit in case there's a cop lurking
behind the bushes ready to give you a speeding ticket.
· Don't speed when you
are the only car on the road. If you ignore this
warning it's the equivalent of plastering a "ticket me!" bumper
sticker on your vehicle. Even if you're only doing five mph over the posted
limit, if there's a cop using radar, he's got nothing to look at but you.
Lonesome speeding is even more dangerous in small towns, where radar traps and
aggressive enforcement by cops can be common. And never speed late at night.
Drunk-driving patrols are heavy and cops are more inclined to pull you over for
any offense in order to check you for signs of alcohol. Don't give them a
reason.
· If it's OK legally, get
a radar detector. Yes, they're expensive (good ones,
anyhow). But a one-time hit of, say, $300 for a
decent radar detector is cheaper than even a single big speeding ticket and the
higher insurance costs that
will come with it. Radar detectors are legal in most states and well worth the
investment to avoid a
speeding ticket.
And Finally:
· If possible, drive a
nondescript vehicle. It may not be fair, but
it's human nature to notice things that stand out from the crowd.
Bright-colored cars, those with loud exhaust or other pimped-out enhancements
are the cars more likely to draw a cop's initial attention than
ordinary-looking, family-type cars. Since the cop has to single out one car,
which car do you suppose is the likely candidate for a speeding ticket? The
bright yellow Mustang
GT with 20-inch
chrome rims? Or the silver Taurus?
If you do get pulled over
while driving a fancy, high-profile car, your odds of getting a speeding ticket
versus a warning have probably gone up. If you're driving a fast-looking hot
rod, the cop is going to assume you use it and deserve a ticket more than the
guy in a family-looking ride whose plea that he "didn't realize he was
speeding, officer" comes off as more believable.
· Be aware that
appearances count. That is, your appearance. If your
appearance says, "Responsible member of the community," you're apt to
get a more friendly response than if you look and act like trouble.
The worst possible thing
you can do is combine all the no-no's listed above by driving a flashy car too
fast, late at night when you're the only car on the road while looking like you
just robbed a bank.
If you do that, expect a
speeding ticket. And expect no mercy.
5 Tips to Increase Printer Lifespan
If you take care of your printer, it can last for five to seven years -- and
possibly longer. Although the actual lifespan of any printer depends on how
sturdy it is, the way you use and maintain it will also impact the number of
years it will last.
Here are the do's and don'ts of printer maintenance to help extend its
lifespan and save you money.
Tip No. 1: Keep It Clean
Don't skip the cleaning! A dirty printer won't work as
well for as long.
Do keep your printer running with regular cleaning:
- If you have an inkjet printer and your cartridges have the print heads on
them, you should clean the print heads. Remove the cartridges and use a moist
cloth to wipe away the accumulated dry ink. Be sure to change the cartridges in
a timely manner and only use the highest-quality cartridges to avoid leaks.
- If you have a laser printer, clean the soft, rubber coating on the rollers
with a moist cloth. In addition, vacuum the inside of the printer to remove
toner particles.
Tip No. 2: Buy Quality Toner/Ink Cartridges
Don't be cheap by buying compatible, refilled or
remanufactured ink/toner cartridges. They cost less, but they don't work as
well or as long, and they can impair your printer's performance.
Do buy the toner/ink cartridges that are specifically recommended for your
printer. It's helpful to keep a spare cartridge on hand so you have a new one
immediately available when the old one needs to be replaced. Be sure to recycle
the used cartridge.
Tip
No. 3: Don't Use Force on a Paper Jam
Don't yank out the paper when it's jammed! Not only
can this rough action damage the printer, but also it can shred some of the
paper, leaving bits of paper inside that can cause damage later on.
Do look for the hatch on the back of the printer. This can easily be removed,
allowing you access to the paper wheels. You should be able to see the jammed
paper and gently extract it.
Tip No. 4: Print Judiciously
Don't print needlessly. Before you print, ask yourself
this question: "Do I really need to print this?"
Don't print unless you really need a paper document. After all, the less you
print, the longer your printer will last. Besides, it's the green thing to do,
since you'll use less paper and save a tree. One exception: If you have an
inkjet printer, you should print frequently enough to prevent the print heads
from clogging.
Do use the print preview function to see how a document will look when it's
printed so you can make necessary changes and print just once.
Tip No. 5: Turn Off the Printer Properly
Don't suddenly turn off the printer or pull the cord
out of the electrical outlet in the middle of a printing job.
Do use the printer's power button to turn off the machine when it's not in use
to prevent the ink from drying out and keep your printer functioning at its
best.
