Dengue virus turns on mosquito genes that make them hungrier

Friday, March 30, 2012

Researchers at the Johns Hopkins Bloomberg School of Public Health have, for the first time, shown that infection with dengue virus turns on mosquito genes that makes them hungrier and better feeders, and therefore possibly more likely to spread the disease to humans. Specifically, they found that dengue virus infection of the mosquito's salivary gland triggered a response that involved genes of the insect's immune system, feeding behavior and the mosquito's ability to sense odors. The researchers findings are published in the March 29 edition of PLoS Pathogens.

Dengue virus is primarily spread to people by the mosquito Aedes aegypti. Over 2.5 billion people live in areas where dengue fever is endemic. The World Health Organization estimates that there are between 50 million and 100 million dengue infections each year.

"Our study shows that the dengue virus infects mosquito organs, the salivary glands and antennae that are essential for finding and feeding on a human host. This infection induces odorant-binding protein genes, which enable the mosquito to sense odors. The virus may, therefore, facilitate the mosquito's host-seeking ability, and could?at least theoretically?increase transmission efficiency, although we don't fully understand the relationships between feeding efficiency and virus transmission," said George Dimopoulus, PhD, senior author of the study and professor with the Bloomberg School's Malaria Research Institute. "In other words, a hungrier mosquito with a better ability to sense food is more likely to spread dengue virus."

For the study, researchers performed a genome-wide microarray gene expression analysis of dengue-infected mosquitoes. Infection regulated 147 genes with predicted functions in various processes including virus transmission, immunity, blood-feeding and host-seeking. Further analysis of infected mosquitoes showed that silencing, or "switching off," two odorant-binding protein genes resulted in an overall reduction in the mosquito's blood-acquisition capacity from a single host by increasing the time it took the for mosquito to probe for a meal.

"We have, for the first time shown, that a human pathogen can modulate feeding-related genes and behavior of its vector mosquito, and the impact of this on transmission of disease could be significant," said Dimopoulos.

"Dengue virus infection of the Aedes aegypti salivary gland and chemosensory apparatus induces genes that modulate infection and blood-feeding behavior" was written by Shuzhen Sim, Jose L. Ramirez and George Dimopoulos.

Sunny Health & Fitness Pro Indoor Cycling Bike | Gain Muscle Size

Bodybuilding March 30th, 2012

I recently purchased the Sunny Health & Fitness Pro Indoor Cycling Bike. I?ve utilised it several times and I am just very happy which i went using this type of bike.

I can?t talk about other equivalent priced bikes available on the market ($250-$500 range), but I don?t think you can not work out using this bike if you?re not looking to invest over a new $1000 with a decent spinning bike.

I?m not really a hardcore rewriter, but I?ve gone to enough tuition at different gyms to learn that this bike performs just and also $1000+ ones I?ve made use of at industrial gyms. It?s got the very same feel since those bicycles, and that?s something MY SPOUSE AND I wasn?t guaranteed I?d be in a bike that charge far much less.

Here are some bullet points to the bike:

-Quick supply.

-box was a bit torn within the corners when i received that. I propose opening the idea up and checking in it?s issue. I truly sent back the initial one I received mainly because I sensed bent metal after i reached in the torn hole. However, I thought to open up cost-free one plus discovered that the bent sheet metal was a new ?protective piece? to avoid damage on the front with the bike. Just take care when people open it just in case there may be a problem and you should tape this box ? up ? and post back!

-I?m 5?11? as well as 190 fat and I?d no trouble adjusting the particular seat plus handle bars to get to a relaxed and correct riding situation.

-the wheel spins smoothly plus the resistance will be consistent along with ample. The busting lever works great at the same time. I bought a of our resistance bike a decade ago plus it?s currently dismantled and collecting airborne dirt and dust. If you will be undecided between the two, take it from myself, go considering the ?spin class? type bike! You do not need a calorie or maybe distance counter-top.

if you don?t feel just like you?re being employed or not really sweating, you are going to know it. If you require a coronary heart rate monitor, go with one of the watch kinds?they?re far more accurate than possessing a cardiovascular exercise machine?s handlebars to get a reading.

Overall, 5 beyond 5 with this bike. I?m sure more costly ones have more possibilities or gadgets that will be useful for that hardcore spinners, but in case you are like myself and in spinning however don?t need the extras and the added cost to receive them, then select this bike.

NAR: Low Real Estate Prices, Desire for Family Retreat Propel ...

AUSTIN, Texas, March 29, 2012 /PRNewswire/ ? In a sign of an emerging recovery in the real estate market, sales of vacation homes in 2011 reached a four-year high, powered by the lowest median sales price in eight years, low mortgage rates, and the desire for a family retreat, according to proprietary research commissioned by HomeAway, Inc. as part of the National Association of Realtor?s (NAR) 2012 Investment and Vacation Home Buyers Survey?.

The research found 33 percent of vacation home buyers purchased a vacation property last year primarily because of low real estate prices, while another 30 percent cited the desire for a family retreat. And 2011 proved an opportune time to buy, according to the NAR survey, with the median sales prices for vacation properties at $121,300, putting ownership within greater reach of more consumers.

Other vacation home buyers cited the following factors as the most important reason to take the plunge into vacation home ownership last year, according to HomeAway? research:

Low mortgage rates (13%)
For future retirement (11%)
Potential for price appreciation (8%)
Other (5%)

?The purchase of vacation homes is moving back into the mainstream for a greater number of Americans who are attracted by low prices, rental income potential, and use as a retreat for busy families to get together every year,? says Brian Sharples, chief executive officer of HomeAway. ?Although sales of vacation homes are not as high as historic levels, they are clearly showing signs of a sustained recovery.?

According to the NAR survey, 82 percent of buyers believe now is a good time to purchase real estate, and 39 percent say they are somewhat or very likely to buy vacation property within the next two years.

Vacation Home Owners Believe Rental Income Can Help Offset Mortgage on Second Home

Nearly all (91%) vacation home buyers say they plan to rent their property within the next 12 months to either long-term or short-term renters or a combination of the two. Of those buyers, 71 percent cited rental income potential as a factor in their purchase decision and nearly three-quarters (74.5%) of buyers believe they will make enough rental income to cover at least half of their mortgage.

According to Sharples, HomeAway research conducted in Q4 of 2011 of 4,905 owners listing their vacation homes on HomeAway?s U.S. sites show that 70 percent generate enough rental income to cover half or more of their mortgage, and 51 percent cover at least three-fourths of their mortgage.

Of those buyers intending to rent their property, about 40 percent plan to make their vacation homes available for rent between one and eight weeks over the course of the next year; 32 percent plan to rent their properties between nine and 26 weeks per year; and 27 percent plan to rent their homes between 27 and 52 weeks per year.

Vacation home buyers are willing to rent their property to more than one type of guest. The majority (70%) of people who plan to rent their property to short-term renters say they?ll rent the home to vacationers, while 37 percent plan to rent to business travelers and 24 percent plan to rent to other tenants, such as college students or people relocating to the area.

By the Numbers:

Highlights from the NAR 2012 Investment and Vacation Home Buyers Survey

502,000 ? Number of vacation homes sold in 2011 $121,300 ? The median sales price of a vacation home in 2011, down 19% from 2010
38 ? Percentage of vacation home buyers under the age of 45 $88,600 ? Median household income of vacation home buyers
42 ? Percentage of vacation home buyers who paid cash for their property
69 ? Percentage of vacation home buyers who plan to own their property more than six years
33 ? Percentage of vacation home buyers saying they are very or somewhat likely to buy another property within the next two years

Jewellery That Lets You Create A Number Of Different Looks

The way that Nomination charm bracelets differ from other bracelets is that with traditional bracelets, charms will attach on the bracelets whereas the Nomination charms connect together to make the bracelet- they just clip in. Nomination bracelets can be begun by a starter bracelet which are made-up of lots of simple links connected together that are then replaced by the charms as you progressively buy them (this means that you don't have to purchase all your desired charms at once!).

Hammerhead shark twin discovery creates concern for species

The scalloped hammerhead shark has a twin, scientists have discovered. And that discovery may show that scalloped hammerheads are rarer than first thought.

Scientists recently confirmed that endangered scalloped hammerhead sharks have a fishy twin ? a newfound species, still unnamed, that is distinct, yet very closely resembles the threatened sharks.

Skip to next paragraph

The case of mistaken identity indicates that scalloped hammerhead sharks?are even more scarce than once thought, according to some researchers.

Since it's very hard to tell the two species apart ? only differences in their DNA and number of vertebrae reveal their true identities ? it's likely that previous assessments of scalloped hammerhead sharks exaggerated their numbers because the counts likely included the look-alike sharks.

"It's a classic case of long-standing species misidentification that not only casts further uncertainty on the status of the real scalloped hammerhead, but also raises concerns about the population status of this new species," Nova Southeastern University Oceanographic Center professor Mahmood Shivji said in a statement.

Shivji's team at the Florida university first discovered the new hammerhead species in 2005 when examining the DNA of sharks thought to be scalloped hammerheads based on their physical appearance. A research team from the University of South Carolina independently confirmed the existence of the new species in 2006.

Combined genetic assessments from both institutions show that at least 7 percent of the sharks in U.S. waters originally thought to be scalloped hammerheads turned out to be the newly identified species.?

Now, researchers have found the unnamed shark, a so-called "cryptic" species, swimming in waters off the coast of Brazil, thousands of miles from where the species was initially discovered. The find indicates the cryptic species is widespread, and may be facing similar pressure as its nearly identical cousin.

Shark populations around the world have declined precipitously in recent decades, with millions of the iconic fish falling victim to the grisly practice of finning.

Shark fins fetch a high price in China, where they are used for shark fin soup.

Shark finning is largely banned in the United States, and many individual states have banned the trade and possession of shark fins. However, evidence from around the world indicates that finning continues to claim millions of shark lives each year.
