Wearing Flip-Flops May Have Bad Repercussions on Your Feet



As the summer set in, most people want to feel as free as they can be when it comes to clothes and footwear. And what can be more comfortable during summer walks than flip-flops. However, according to a new study, flip-flops can be very bad for your feet and legs.
Researchers from Auburn University in Alabama recruited 39 college-age men and women and asked them to wear flip-flops or athletic shoes while walking on a special platform. The study found that when participants wore flip-flops, they took shorter strides and their heels hit the ground with less vertical forces than when they wore athletic shoes.
Therefore, wearing flip-flops can result in altering people’s gait, “which may explain why we see some lower leg and foot problems in people who wear these shoes a lot,” study author Justin Shroyer, a graduate student in Auburn’s department of kinesiology said, according to the New York Times.
The results of the study should not discourage people from wearing flip-flops, Shroyer said. However, he added that people should wear them for short periods of time, (especially people with pain in their legs and feet), as this kind of footwear is not designed to properly support the foot and ankle during all-day wear.

Boy Dies From Secondary Drowning In South Carolina


June 6 2008 - A 10 year old boy named Johnny Jackson has died just hours after leaving a swimming pool in his apartment complex in Goose Creek, and it is believed he died from secondary drowning.
He died several hours after exiting the pool, thus the theory is that he died from secondary drowning from taking in too much water while he was in the pool swimming.
According to the county coroner, Jackson died with water in his lungs resulting in his death via "asphyxiation by drowning."
Speaking with ABC news, his mother Cassandra Jackson said that her son seemed to be fine: "He seemed to be fine," she said. "I noticed nothing out of the ordinary, other than him taking a little bit of water in and coughing and then calming down."
"I rolled him over and his body was very limp and I realized he'd soiled himself again and was very purplish-blue looking," Jackson tells the network. "His
tongue was really swollen, too."
Jonny was reportedly autistic, but this in no shape or form contributed to his death.
His mother says that all mothers should check their children when they come out of the water after swimming: "Please check them when they get out of the pool. Just watch them like a hawk," she told a newspaper. "It tears me up inside. It's a heck of a sacrifice, but if this will help someone else, then it's all worth it."

Indian boffin uncovers vitamin B3’s role in maintaining good cholesterol


Washington, June 6 : A team led by an Indian researcher claim to have uncovered how niacin (vitamin B3) helps in maintaining good cholesterol levels, thus reducing the risk of developing heart disease.
Niacin can increase plasma HDL levels, however, the mechanism of how it works has been mysterious. Some researchers also believed that niacin does not actually increase HDL production.
The work also identifies a new drug target, as no other drug in currently known to raise HDL by inhibiting the surface expression of the beta chain of ATP synthase.
The new study has found that a component of ATP synthase (the protein that makes ATP) is present on the surface of liver cells, and this subunit known as the 'beta chain' can take up HDL.
The team led by researcher Moti Kashyap found that this beta chain is the basis of niacin's effect.
They added niacin to samples of human liver cells and found that treatment reduced the presence of Beta chain on the cell surface by ~27pct, and as a result HDL uptake was reduced by ~35pct.
This shows that niacin hinders the liver from removing HDL from the blood, thus maintaining high plasma HDL levels.
However, it does not affect another major pathway known as "Reverse Cholesterol Transport."
Therefore, it maintains HDL levels while still allowing the removal of other cholesterol types, explaining why niacin is especially beneficial.
