Scientists detect probable genetic cause of some Parkinson's disease cases

...g in hands, arms, legs, jaw, and face; rigidity or stiffness ofthe limbs and trunk; bradykinesia, or slowness of movement; andpostural instability or impaired balance and coordination. Patients mayalso have difficulty walking, talking, or completing other simpletasks. The disease is both chronic and progressiv...

...reduction in body sway along with increased muscle stiffness following the unpleasant/mutilation block of pictures compared to the neutral pictures. The number of heartbeats per minute was also lower after viewing the mutilation pictures than after looking at the others. "This pattern resembles the 'freezing' ...

Results of world's first gene therapy trial for arthritis show approach safe, feasible

..., patients experience progressively worse pain and stiffness in their affected joints. To block this process, the team sought a way to prevent the main actor, IL-1, from binding to the synovial cells, and hence, setting off the destructive chain reaction that follows. In essence, they needed a way to plug up ...

...ngineering and Science. Love said, "The resulting stiffness and strength of the laminated structures has not been fully evaluated, but qualitative testing has shown that these structures are demonstrably stiffer than the current commercial devices already available." Love added that the new bracing system wi...

New molecule may aid in production of biofuels and fungi-resistant plants

... organisms. For example, chitin gives strength and stiffness to the shells/cuticles of shrimps and insects and to the cell walls of fungi. Because chitin is an abundant resource and, most importantly, because it occurs in several types of plague organisms and parasites, chitin degradation is of great interest ...

Carnegie Mellon researchers discover new cell properties

...s science and engineering, says that the increased stiffness of the lamina may be caused by mutant proteins self-organizing into ordered structures within the HGPS lamina. "This could make the lamina stiffer and cause fractures in the nuclei," Islam said. The healthy lamina remains disordered and therefore le...

3-D model reveals secrets of metastasis

...hat the cells become dramatically sensitive to the stiffness of the vines when the integrins are disabled and consequently tend to squeeze through the vines rather than pushing them aside. "Our findings help explain why two-dimensional assays for metastasis-inhibiting drugs do not effectively predict their e...

NIH announces phase III clinical trial of creatine for Parkinson's disease

... as progressive tremor, slowness of movements, and stiffness of muscles. It affects at least one million people in the United States. Although certain drugs, such as levodopa, can reduce the symptoms of PD, there are no proven treatments that can slow the progressive deterioration in function. Creatine is...
