(Press-News.org) After development of diffusion tensor tractography (DTT), which is derived from diffusion tensor imaging (DTI), three-dimensional reconstruction and estimation for three motor tracts, such as the corticospinal tract, the rubrospinal tract, and the corticoreticular pathway became possible. The corticospinal tract is known to be a major neural tract for motor function in the human brain. Several studies have reported on injury of the corticospinal tract by transtentorial herniation. In addition, some studies have demonstrated recovery of a corticospinal tract injured by transtentorial herniation. However, very little is known about injury and recovery of the corticospinal tract related to subfalcine herniation. Researchers at College of Medicine, Yeungnam University, Republic of Korea, led by Prof. Sung Ho Jang report on a 53-year-old, male patient with subdural hematoma in the right fronto-parietal-temporal lobe and subfalcine herniation patient who showed recovery of the corticospinal tract, which was injured by the effect of a subfalcine herniation, using DTT. The patient underwent decompressive craniectomy and removal of a hematoma at admission. At 6 weeks after onset, he was transferred to the rehabilitation department for rehabilitation. His weakness was recovered to a nearly normal state at 7 months after onset. DTT results showed that both corticospinal tracts were narrowed from the cerebral cortex to the subcorical white matter at 6 weeks after onset; however, thickenings of narrowed portions of both corticospinal tracts on 7-month DTT appear to indicate recovery of the injured corticospinal tracts. The recovery of the injured corticospinal tracts induced by subfalcine herniation may be a result of neurological remodeling under rehabilitation intervention. This article is released on the Neural Regeneration Research (Vol. 9, No. 12, 2014).

Bacteria manipulate salt to build shelters to hibernate
2014-07-25
For the first time, Spanish researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water and is left to dry, bacteria manipulate the sodium chloride crystallisation to create biomineralogical biosaline 3D morphologically complex formations, where they hibernate. Afterwards, simply by rehydrating the material, bacteria are revived. The discovery was made by chance with a home microscope, but it made the cover of the Astrobiology journal and may help to find signs of life on other ...
Breakthrough laser experiment reveals liquid-like motion of atoms in an ultra-cold cluster
2014-07-25
A new study by researchers from the University of Leicester has furthered our understanding of how tiny nanosystems function, unlocking the potential to create new materials using nanosized 'building blocks'.
The study, which has been published in the prestigious academic journal Physical Review Letters, used a novel laser technique to examine in rich detail the structure and internal atomic motion of a small cluster containing an acetylene molecule and a single helium atom.
The technique excited single clusters and generated rotational wavepackets, which are composed ...
Magnets for fusion energy: A revolutionary manufacturing method developed
2014-07-25
The National Institute for Fusion Science (NIFS), of the National Institutes of Natural Sciences (NINS) in Japan, has achieved an electrical current of 100,000 amperes, which is by far the highest in the world, by using the new idea of assembling the state-of-the-art yttrium-based high-temperature superconducting tapes to fabricate a large-scale magnet conductor.
NIFS is undertaking the development of a high-temperature superconducting coil that is appropriate for the fusion reactor magnet. Using the state-of-the-art yttrium-based high-temperature superconducting tapes ...
Physicists create tool to foresee language destruction impact and thus prevent it
2014-07-25
There have been numerous cases of cultural changes throughout history. Either by imposition or assimilation, cultural traits are transmitted between neighbouring regions and often one replaces the original cultural traits of the other. Physicists Joaquim Fort, from the University of Girona (UdG), and Neus Isern, from the Universitat Autònoma de Barcelona (UAB), are experts in modelling these phenomena by adequately representing a reality, as they have demonstrated with their previous projects.
In this occasion, the researchers applied their expertise to the area of language ...
Collecting just the right data
2014-07-25
Much artificial-intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon and Netflix.
But some types of data are harder to collect than online click histories —information about geological formations thousands of feet underground, for instance. And in other applications — such as trying to predict the path of a storm — there may just not be enough time to crunch all the available data.
Dan Levine, an MIT graduate student in aeronautics and astronautics, and ...
Could age of first period influence development of diseases in older women?
2014-07-25
BOSTON—A novel study shows that the age girls reach puberty is influenced by 'imprinted genes'—a subset of genes whose activity differs depending on which parent contributes the gene. This is the first evidence that imprinted genes can control the rate of development after birth and details of this study were published today in the journal Nature.
Age of the first period, known as menarche, is a marker for the timing of puberty in females. Medical evidence shows that the onset of menses varies between girls, is an inherited trait, and is linked to breast cancer, diabetes ...
It takes two to court
2014-07-25
KANSAS CITY, MO—Researchers at the Stowers Institute for Medical Research have identified the functions of two classes of pheromone receptors, and found pheromones crucial to triggering the mating process in mice.
They found one class of receptors helps a male mouse detect pheromones that indicate when a female is present. The other class of receptors lets him know if the female mouse is ovulating and ready to mate. Both sets of pheromones are critical to trigger mating. Stowers' researchers believe mice developed this system through evolution to maximize the chance of ...
Experiences at every stage of life contribute to cognitive abilities in old age
2014-07-25
Early life experiences, such as childhood socioeconomic status and literacy, may have greater influence on the risk of cognitive impairment late in life than such demographic characteristics as race and ethnicity, a large study by researchers with the UC Davis Alzheimer's Disease Center and the University of Victoria, Canada, has found.
"Declining cognitive function in older adults is a major personal and public health concern," said Bruce Reed, professor of neurology and associate director of the UC Davis Alzheimer's Disease Center.
"But not all people lose cognitive ...
Why do men prefer nice women?
2014-07-25
People's emotional reactions and desires in initial romantic encounters determine the fate of a potential relationship. Responsiveness may be one of those initial "sparks" necessary to fuel sexual desire and land a second date. However, it may not be a desirable trait for both men and women on a first date. Does responsiveness increase sexual desire in the other person? Do men perceive responsive women as more attractive, and does the same hold true for women's perceptions of men? A study published in Personality and Social Psychology Bulletin seeks to answer those questions. ...

Heart attack patients could be treated more quickly after Manchester research
Clinical judgement, combined with an electrocardiogram (ECG) and blood test on arrival, is effective in reducing unnecessary hospital admissions for chest pain, a new study shows.
The findings of a research group in Manchester, published in the Emergency Medicine Journal, could potentially make a huge difference to a large number of patients.
Chest pain is the most common reason for emergency hospital admission. In Manchester, the incidence of premature death due to heart disease and stroke ...
