(Press-News.org) Transient ischemic attack (TIA) is a temporary event, which portends a higher risk of a disabling stroke following the TIA. However, the evaluation and management of TIA vary worldwide and is debated and controversial. Dr. Mohamed Al-Khaled from University of Lübeck in Germany considered With the development of brain imaging, particularly diffusion weighted imaging-magnetic resonance imaging (DWI-MRI), the diagnosis of TIA changed from time-based definition to a tissue-based one. DWI-MRI became a mandatory tool in the TIA workup. The DWI-MRI provides not only the evidence to distinguish between TIA and acute ischemic stroke, furthermore it predicts TIA patients who are at higher risk of disabling stroke, which can be prevented by an immediate evaluation and treatment of TIA These findings, published in the Neural Regeneration Research (Vol. 9, No. 3, 2014).

Ligaments disruption: A new perspective in the prognosis of SCI
2014-07-31
Worldwide prevalence of Spinal Cord Injury (SCI) is ranging from 233 to 755 per million inhabitants, whereas reported incidence lies between 10.4 and 83 per million inhabitants per year. Thus, the socioeconomic impact of SCI associated with cervical trauma is high enough to be encountered within one of the most important worries in vast majority of developed countries.
The ability to predict recovery following SCI is of paramount importance to the physician's role in providing the best care and guidance to patients and families during the illness. Diagnosis of cervical ...
Brother of Hibiscus is found alive and well on Maui
2014-07-31
Most people are familiar with Hibiscus flowers- they are an iconic symbol of tropical resorts worldwide where they are commonly planted in the landscape. Some, like Hawaii's State Flower- Hibiscus brackenridgei- are endangered species.
Only a relatively few botanists and Hawaiian conservation workers, however, are aware of an equally beautiful and intriguing related group of plants known as Hibiscadelphus- literally "brother of Hibiscus".
Brother of Hibiscus species are in fact highly endangered. Until recently only one of the seven previously known species remained ...
Singing the same tune: Scientists develop novel ways of separating birdsong sources
2014-07-31
Researchers at the University of California, Los Angeles and the Chinese Academy of Sciences have pioneered a new study that could greatly improve current methods of localising birdsong data. Their findings, which ascertain the validity of using statistical algorithms to detect multiple-source signals in real time and in three-dimensional space, are of especial significance to modern warfare.
Recently published in the journal Unmanned Systems, the study demonstrates the validity of using approximate maximum likelihood (AML) algorithms to determine the direction of arrival ...
Gulf oil spill researcher: Bacteria ate some toxins, but worst remain
2014-07-31
TALLAHASSEE, Fla. — A Florida State University researcher found that bacteria in the Gulf of Mexico consumed many of the toxic components of the oil released during the Deepwater Horizon spill in the months after the spill, but not the most toxic contaminants.
In two new studies conducted in a deep sea plume, Assistant Professor Olivia Mason found a species of bacteria called Colwellia likely consumed gaseous hydrocarbons and perhaps benzene, toluene, ethylbenzene and xylene compounds that were released as part of the oil spill.
But, her research also showed that bacteria ...
Hope for the overweight
2014-07-31
White, brown and beige adipocytes, or fat cells, are inherently different. Each of these cell types has different functions and each plays its own role in metabolism. In the human body, white adipose tissue is by far the most prevalent. Its primary function is energy storage. On the other hand, brown adipocytes utilize available energy to generate heat but are only found in a few places in the adult human body. Beige adipocytes, which represent a special type of brown adipocytes, appear mixed with brown adipocytes in human brown adipose tissue or develop within the white ...
Privileged strategies for direct transformations of inert aliphatic carbon-hydrogen bonds
2014-07-31
Functional group transformations are central to organic synthesis. Traditionally, the functionalities used in such transformations are highly active organic groups such as halogens, ester groups and hydroxyl groups. Carbon–hydrogen bonds are ubiquitous structural motifs in organic compounds, but they are not considered to be functional groups because (1) in general, the bond dissociation energy of a C–H bond is high, and therefore, such bonds are thermodynamically hard to break; and (2) the selective activation of one C–H bond among many similar and different C–H bonds ...
Neutron tomography technique reveals phase fractions of crystalline materials in 3-dimensions
2014-07-31
The method overcomes limitations of existing techniques which are limited to the surface or small-sized specimens, and allows a 3-D representation of the phase fractions within the sample volume. The work has just been published in the journal "Advanced Materials".
"For many engineering applications it is of major importance to characterize the bulk of materials spatially, instead of only probing selected locations. The new method provides exactly that capability, and the HZB-UTK team has demonstrated it by using samples made from stainless steel that undergo a phase ...
Vision-correcting electronic displays could let users dispense with glasses
2014-07-31
Researchers at the MIT Media Laboratory and the University of California at Berkeley have developed a new display technology that automatically corrects for vision defects — no glasses (or contact lenses) required.
The technique could lead to dashboard-mounted GPS displays that farsighted drivers can consult without putting their glasses on, or electronic readers that eliminate the need for reading glasses, among other applications.
"The first spectacles were invented in the 13th century," says Gordon Wetzstein, a research scientist at the Media Lab and one of the display's ...
Vacuum treatment may limit damage after traumatic brain injury
2014-07-31
July 31, 2014 – Controlled application of vacuum pressure is a promising approach to limiting tissue damage after traumatic brain injury (TBI), suggests an experimental study in the August issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
"Mechanical tissue resuscitation"—consisting of vacuum pressure applied over the injured area of the brain—shows promise as a safe and effective treatment for TBI, according to the research report by Dr. Louis ...
UT Dallas study reveals effect of loud noises on brain
2014-07-31
Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists at The University of Texas at Dallas.
In a paper published this week in Ear and Hearing, researchers demonstrated for the first time how noise-induced hearing loss affects the brain's recognition of speech sounds.
Noise-induced hearing loss (NIHL) reaches all corners of the population, affecting an estimated 15 percent of Americans between the ages of 20 and 69, according to the National Institute ...
