A glass of orange juice a day, can keep the recurrence of kidney stones away, researchers at UT Southwestern Medical Center have discovered.
According to the findings of the study, orange juice can help prevent the recurrence of kidney stones better than other citrus fruit juices including lemonade.
People assume that all citrus fruit juices help prevent the formation of kidney stones, not all have the same effect. If the recurrence of kidney stones has to be medically treated, it requires dietary and lifestyle changes.
It also requires treatment including the addition of potassium citrate, which has been shown to lower the rate of new stone formation in patients with kidney stones.
However, since some patients can't tolerate potassium citrate because of gastrointestinal side effect, dietary sources of citrate including orange juice may be considered as an alternative to pharmacological drugs.

Smoking could ruin your sex life
The new study says, Smoking could ruin your sex life as it can increase the risk of erectile dysfunction among men.
And the more cigarettes smoked, the greater the risk, found the research that studied 7,684 men between the ages of 35-74.
The study found that there was a significant statistical link between the number of cigarettes that men smoked and the likelihood of them experiencing erectile dysfunction.
Indian doctor develops enzyme that can destroy HIV
Dr Indrani Sarkar has has every reason to be excited. Her PhD thesis, which started in 2002 at the Max Planck Institute in Dresden, Germany, has thrown open the doors for developing enzymes that can destroy the dreaded Human Immuno-deficiency Virus or HIV within infected cells permanently.
Indrani and a team of scientists have developed an enzyme called Tre. Tre is a custom enzyme capable of detecting, recognising and destroying HIV, much like a pair of molecular scissors.
"In laymans terms, it's an engineered enzyme which recognises sequences in the HIV genome that is duplicated, integrated virus and by the process of recombination, it cuts out the virus from the genome," says she.
The biggest challenge with treating HIV today is that the virus becomes dormant and often develops resistance to HIV drugs.
The only way then to cure HIV is to get rid of the virus completely and Tre, the enzyme that Indrani constructed after a year and its 126 "cycles of mutation" totally deplete HIV in the human genome in three months in laboratory conditions.
"It's a beautiful approach, but like any other drug, this one too will take a few years to reach clinics — anywhere between five and 20 years actually. A lot of research has to be done because since one is working with a novel enzyme, one has to engineer the enzyme," says she

Sleepless Nights Make for Grumpier Brains
A new study finds that a lack of sleep causes the brain's emotional centers to dramatically overreact to negative experiences.
A shutdown of the prefrontal lobe -- a brain region that normally keeps emotions under control -- is the reason for heightened emotional response in sleep-deprived people.
Reporting in the Oct. 23 issue of the journal Current Biology, the team said its study is the first to determine, at the neural level, why lack of sleep can lead to emotionally irrational behavior and may help improve understanding of the link between sleep disruptions and psychiatric disorders.
"This adds to the critical list of sleep's benefits," Matthew Walker of the University of California, Berkeley, said in a prepared statement. "Sleep appears to restore our emotional brain circuits, and, in doing so, prepares us for the next day's challenges and social interactions. Most importantly, this study demonstrates the dangers of not sleeping enough. Sleep deprivation fractures the brain mechanisms that regulate key aspects of our mental health."

Alappuzha Boating
With the Arabian Sea on the west and a vast network of lakes, lagoons and fresh water rivers crisscrossing it, Alappuzha is a district of immense natural beauty in Kerala.Referred to as the Venice of the East by travellers from across the world, this backwaters country is also home to diverse animal and bird life.
By virtue of its proximity to the sea, the town has always enjoyed a unique place in the maritime history of Kerala. Today, Alappuzha has grown in importance as a backwater tourist centre, attracting several thousands of foreign tourists each year.
Alappuzha is also famous for its boat races, houseboat holidays, beaches, marine products and coir industry. A singular characteristic of this land is the region called Kuttanad.
