Artificial Bone May Printed With 3-D Printer

Jakarta,  Various abnormalities or bone damage is now more easily overcome. The scientists succeeded in modifying the 3-dimensional printer, to be able to print the artificial bone to replace the original bone is broken or defective and can not be repaired.

This new breakthrough is believed to be very useful for orthopedic surgeons, dentists and people with osteoporosis or thinning of bone mass. Its main function is to develop an artificial bone tissue, and then shape it as closely as possible to the original bone.

“Doctors can get the desired bone shape through regular scan tool, then the data is connected to the printer,” says Prof. Susmita Bose of  Washington State University  who found such tools as quoted from  CBS News.

Artificial bone that is printed with this printer has been tested on rats and rabbits and the results published in the journal  Dental Materials . Human trials in a matter of time, and if successful then in the next few years these tools began to be marketed.

The workings of the bone printer is basically the same as 3-dimensional printer used to print metal materials. It’s just, ‘ink’ is replaced with calcium phosphate as in the original bone and mixed with dough zinc and silicon.

Section ejects ink will spray the dough on a kind of nucleus, whose size is no wider than a human hair. Bursts were carried out layer by layer until it reaches a certain thickness the size of an eraser.

Candidates for the eraser-sized bone was then removed from the printer, and then stored in a highly controlled conditions in the laboratory in order to grow as native bone. In recent weeks, the artificial bone that is printed with a printer that was to be grafted.

Healthy Habits Trasmitted Character of The Friends of Same

Jakarta,  As the saying goes, a good friend will lead to good things, as well as for healthy habits. People who have healthy habits will pass on healthy habits to his friends. However certain conditions, the friend should have the same characteristics with him.

Researchers at the Massachusetts Institute of Technology found that include people who have similar properties in the social network to improve physical fitness can merubahan become more healthy lifestyle.

People who are obese are more likely to commit new activity in healthy when grouped with other obese people, but not when grouped with people who are skinny.

According to the researchers, the social environment is the most effective increase of obese people desire to follow the behavior of others with similar health characteristics.

“You will see more weight loss programs are designed in the social network and as a result, I think the program will be more successful,” said Ray Browning, physiologist at Colorado State University who has studied health interventions and social networks, but not involved in this study.

In this study, researchers looked at 710 research participants. Most of them are women who have been enrolled in an online fitness program. Participants were divided into two groups. The first group was given the task of social networking groups at random. The second group was assigned to be given a “health friend” others by age, sex and BMI (body mass index) of the same.

Participants can view your friends profile of health and fitness activities are done like how much time is spent on exercise and whether his friend wrote down the food he has eaten in the “diet diary”.

Researchers target is actually this diary because I wanted to see whether the study participants will look after each other in the group. The researchers found that being in the same friendship network characteristics make people three times more likely to make healthy new habits.

“People are often blamed for obesity because of a lack of physical activity. Our study provides evidence that it’s not entirely true. It could be that it was highly influenced by their social networks. For example, if your friends go to bars and not exercising in her spare time, you will tend to go with them, rather than going to the gym alone, “Browning said as quoted by LiveScience.

According to researchers, behavior change will be easier if it brings new people into the group of friends who can bring good habits and activities that promote health, such as a personal trainer.
