Brain Vacuum Reverses Stroke Damage

A new tool developed by researchers, the Penumbra  System of Continuous Aspiration Thrombectomy,  vacuums out clots from blood vessels in the brain, and  can reverse the effects of stroke if used within in a few  hours of the incident.

The process involves threading a tiny catheter into a blood vessel up from the groin to the neck, at which point an even smaller catheter emerges and goes up into the brain.

The procedure only works on victims of massive strokes, so patients must receive a CT scan as soon as possible.

Sorsogon State College-studes find diode effective power saving device

by M Moraleda and D Deri/SSC/PIA Sorsogon

Sorsogon City (11 June) — In the light of crafting ways to minimize electric power consumption, the fifth year electrical engineering students of the Sorsogon State College here, have finished a research study on Light Emitting Diode (LED) as an alternative electronic component in designing a lighting device.

The design proposed by Zendy Dematera, Dyronne P. Ajas, Gissell C. Dogillo and Rusan James Freo was adjudged best among the six competing groups and was given credit by the SSC in its recognition ceremony last March.

Engr. Joselito S. Orticio, who handles the students, said that the study was one of the requisites in their subject as well seminars and field trips where the students were exposed to.

“The research is only limited to the utilization of white LED which can possibly be an efficient source to replace the usual lighting system for domestic use,” said Orticio.

The four researchers, after conducting the study, found out that it is possible to create a LED light bulb which can be directly connected to a 230V/.AC.

It was also proven to be energy-saving due to its low power consumption, producing a light output of 120.6 lumens and a power of 1.2 watts.

“It is also advantageous because its materials are more durable compared to the typical compact fluorescent lamps and bulbs which have fragile components. Furthermore, though costly, it has a longer lifespan and contains no mercury unlike other usual bulb designs,” said the researchers.

Since it has poor illumination, they recommended the use of an efficient reflector that will suit the design of the bulb. “It is also imperative to utilized high-powered LED to make it a more effective lighting device,” they also said. (SSC/PIA Sorsogon) [top]

Pay with your life for a younger hubby

Women who marry significantly younger men, or significantly older men, have a shorter life expectancy than women who wed males about their own age, according to new findings by German scientists.

Previous studies showed that men with younger wives live longer. For years, researchers thought that this data was true for both sexes.

They assumed that an effect called “health selection” was in play – those who select younger partners are able to do so because they are healthier and thus already have a higher life expectancy.

It was also thought that a younger spouse has a positive psychological and social effect on an older partner and can be a better caretaker in old age, thereby helping to extend the partner’s life.

In a new study, however, Dr Sven Drefahl of the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany, has shown that the same is not true for women.
The greater the age difference from the husband, the lower the wife’s life expectancy, regardless of whether the woman is younger or older than her spouse.

“These theories now have to be reconsidered,” Drefahl says. “The reasons for mortality differences due to the age gap of the spouses remain unclear.”
Using data from almost two million Danish couples, Drefahl was able to eliminate the statistical shortcomings of earlier research, and showed that the best choice for a woman is to marry a man of exactly the same age.

An older husband shortens her life, a younger one even more so. According to Drefahl’s study, published in the journal Demography, women marrying a partner seven to nine years younger increase their mortality risk by 20 percent. Hence, “health selection” can’t be true for women.

It is also doubtful that older wives benefit psychologically and socially from a younger husband. This effect only seems to work for men.

While many studies on mate selection show that women mostly prefer men the same age, most of them end up with an older husband.

“On average, men have fewer and lesser quality social contacts than those of women,” Drefahl says.

Thus, unlike the benefits of a younger wife, a younger husband wouldn’t help extend the life of his older wife by taking care of her, going for a walk with her and enjoying late life together. She already has friends for that. The older man, however, doesn’t.

The question that remains is why a younger partner would actually shorten a woman’s life. “One of the few possible explanations is that couples with younger husbands violate social norms and thus suffer from social sanctions,” Drefahl says.

Since marrying a younger husband deviates from what is regarded as usual, these couples could be considered outsiders and receive less social support. This could result in a less joyful and more stressful life, reduced health and finally, increased mortality.

While the new MPIDR study shows that marriage disadvantages most women when they are not the same age as their husband, it is not true that marriage in general is unfavorable.

Being married appears to raise the life expectancy of both men and women above those that are unmarried.
