Migration capacity of human umbilical cord mesenchymal stem cells towards glioma in vivo

2013-09-10
(Press-News.org) Glioblastoma is the most common ma-lignant primary brain tumor in adults. The aggressive growth manner, characterized by marked angiogenesis and extensive tumor cell invasion into normal brain parenchyma with frequent formation of tumor microsatellites at distal sites, makes eradication impossible even after extensive microsurgical resection combined with current standard chemoradiation and adjuvant temozolomide. Thus, novel therapeutic strategies must to be investigated for the development of a more effective treatment strategy. Stem cell-based therapies are emerging as novel cell-based delivery vehicle for therapeutic agents. Prof. Qingjun Zhang and team from the Department of Neurosurgery, Peking University People's Hospital proposed that umbilical cord mesenchymal stem cells may have similar targeting capabilities for glioma. The researchers found that human umbilical cord mesenchymal stem cells demonstrated excellent glioma-specific targeting capacity in established rat glioma models after intratumoral injection or contralateral ventricular administration in vivo. These findings were published in the Neural Regeneration Research (Vol. 8, No. 22, 2013).

New techniques for cerebral white matter fiber tracing

2013-09-10
At present, fiber tracking algorithms are divided into deterministic tractography and probabilistic tractography. In deterministic algorithms, scholars proposed the fiber assignment by continuous tracking algorithm, the tensor deflection algorithm, the tensorline algorithm. Deterministic algorithms track fibers mainly depending on diffusion direction; however, they are susceptible to noise and partial volume effects, which result in the accumulation of tracking errors. Probabilistic algorithms can effectively reduce noise and partial volume effects, thus decreasing the ...

Stress protein expression in early phase spinal cord ischemia/reperfusion injury

2013-09-10
Spinal cord ischemia/reperfusion injury is a stress injury to the spinal cord. Therefore, research on the expression of stress-related protein in neurons could be of great significance for the pathological mechanism and control measures for spinal cord ischemia/reperfusion injury. Previous studies from Dr. Shanyong Zhang and colleagues from China-Japan Friendship Hospital of Jilin University identified 21 differentially expressed proteins in rabbits with spinal cord ischemia/reperfusion injury using differential proteomics. Of these proteins, stress-related proteins included ...

Oil industry and household stoves speed Arctic thaw

2013-09-10
The new study, published in the journal Atmospheric Chemistry and Physics by researchers at IIASA and in Norway, Finland, and Russia, finds that gas flaring from oil extraction in the Arctic accounts for 42% of the black carbon concentrations in the Arctic, with even higher levels during certain times of the year. In the month of March for example, the study showed that flaring accounts for more than half of black carbon concentrations near the surface. Globally, in contrast, gas flaring accounts for only 3% of black carbon emissions. The researchers also found that residential ...

3 out of every 4 cases of bladder cancer display mutations in the same gene

2013-09-10
Researchers from the Spanish National Cancer Research Centre (CNIO) have discovered that more than 70% of bladder tumours display somatic mutations in the TERT gene (telomerase reverse transcriptase). The TERT gene is involved in the protection of DNA and in cellular ageing processes and cancer. These results make this gene the most mutated in these tumours. The study was led by Francisco X. Real, head of the Epithelial Carcinogenesis Group at CNIO, together with Nuria Malats, the head of the Genetic & Molecular Epidemiology Group at CNIO, as well as other European groups, ...

Kids reduce stress in goat herds

2013-09-10
Dairy goats are usually separated from their mothers a few days to weeks after birth and reintroduced into the herd months later – on most farms either in the last months of first pregnancy or shortly after parturition/kidding. The practice is supposed to ensure stable milk production in the herd but it clearly causes stress to the goats. Problems arise because goat herds have a strictly hierarchical social structure and changes in herd composition may lead to serious rivalries and increased aggressive behaviour. Farmers are on the lookout for ways to keep the stress to ...

Life found in the sediments of an Antarctic subglacial lake for the first time

2013-09-10
Evidence of diverse life forms dating back nearly a hundred thousand years has been found in subglacial lake sediments by a group of British scientists. The possibility that extreme life forms might exist in the cold and dark lakes hidden kilometres beneath the Antarctic ice sheet has fascinated scientists for decades. However, direct sampling of these lakes in the interior of Antarctica continues to present major technological challenges. Recognising this, scientists from the British Antarctic Survey (BAS), and the Universities of Northumbria and Edinburgh have been ...

Motorized microscopic matchsticks move in water with sense of direction

2013-09-10
Chemists, physicists and computer scientists at the University of Warwick have come together to devise a new powerful and very versatile way of controlling the speed and direction of motion of microscopic structures in water using what they have dubbed chemically 'motorised microscopic matchsticks'. Before now most research seeking to influence the direction of motion of microscopic components have had to use outside influences such as a magnetic field or the application of light. The University of Warwick team have now found a way to do it by simply adding a chemical ...

Study reveals benefits of wishes on seriously ill children and their parents

2013-09-10
New research has shown that schemes that grant children with a life threatening illness a special wish have a positive impact on their and their family's wellbeing. The research also demonstrates that seeing the child experience their wish was positive for the parents, while often it provoked bittersweet feelings. The study, published in Acta Paediatrica and led by Dr Anne-Sophie Darlington, Senior Research Fellow at the University of Southampton, Professor Passchier and Dr Heule at the Erasmus Medical Centre in the Netherlands, interviewed and surveyed 235 parents ...

New magnetic semiconductor material holds promise for 'spintronics'

2013-09-10
Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor – meaning that it could be used to make "spintronic" devices, which rely on magnetic force to operate, rather than electrical currents. The researchers synthesized the new compound, strontium tin oxide (Sr3SnO), as an epitaxial thin film on a silicon chip. Epitaxial means the material is a single crystal. Because Sr3SnO is a dilute magnetic semiconductor, it could be used to create transistors that operate at room ...

Maya dismembered their enemies

2013-09-10
Researchers of the Department of Anthropology of the Americas at the University of Bonn have discovered a mass grave in an artificial cave in the historical Maya city of Uxul (Mexico). Marks on the bones indicate that the individuals buried in the cave were decapitated and dismembered around 1,400 years ago. The scientists assume that the victims were either prisoners of war or nobles from Uxul itself. For the last five years, archaeologists of the department of Anthropology of the Americas of the University of Bonn have been excavating in the historical Maya city of ...
